Moreover, at the time of safe driving evaluation after the end of the operation, weighted evaluation is possible according to the safety evaluation threshold in consideration of the traveling environment.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.
In the processing flow chart according to the embodiment of the present invention shown in FIG. 1, the operation manager as a client for managing the vehicle is information on a personal computer connected to the Internet installed in each management office branch. Connect to the host computer at the administration office headquarters using terminal equipment.

Then, a mode threshold value for judging a driving environment such as rain or daytime and a safe driving evaluation threshold value (reference value) for each mode can be inputted and set on the Web (step 11). Thereby, the vehicle manager can set conditions from the terminal even in a remote place.
These input data are once set in the host computer of the management office headquarters, and then transmitted to the track by wireless packet communication via the server (step 12). A wireless communication device is loaded on the truck, and the packet communication data is received by these wireless communication devices, and is input and set in the onboard safe driving diagnosis system (step 13).

At this time, the data such as the new safe driving evaluation threshold value received by the traveling truck becomes effective at the next operation. In other words, the set threshold value during the current travel is maintained and applied during the current travel, but becomes effective when the next operation starts after the operation ends.
On the other hand, in a truck, the rain that is the running environment during running is determined by detecting the presence or absence of wiper operation and the elapsed time from the operation (step 14), and determining the day and night by detecting the time data. By comparing (step 15), the mode is determined. In this embodiment, the mode is set to four modes by a combination of rain and day and night.

  The safe driving evaluation items, the safe driving evaluation threshold values for each item, and the mode threshold values for judging the driving environment such as clear rain and day / night must be set for each vehicle or for each of a plurality of vehicle groups. However, it is also possible to set all managed vehicles in a batch. For example, the day and night mode judgment threshold time can be set separately for trucks traveling in the Okinawa area and trucks traveling in the Hokkaido area. it can.

  Next, the safe driving evaluation item and the safe driving evaluation threshold value of each item set for each mode corresponding to the determined mode are selected (step 16), and the set threshold value is called. This threshold value is compared with detection data by a detector such as a speedometer or a tachometer mounted on the vehicle, so that the current driving is within or out of the safe driving evaluation threshold value range. It is determined whether or not the safe driving is performed (step 17).

  Further, the comparison judgment result is recorded in the storage device of the safe driving diagnosis system, and when it is outside the range of the safe driving evaluation threshold, a predetermined message is announced to the vehicle crew so that the vehicle crew To raise awareness of safe driving (step 17). When the operation is completed, the recorded data is read from the storage device mounted on the vehicle-mounted device, and a safe driving radar chart and a safe driving evaluation document are created based on this data (step 18).

Next, the vehicle-mounted device which is one embodiment of the present invention will be described in detail. In the vehicle-mounted device block diagram according to the embodiment of the present invention shown in FIG. 2, the safe driving evaluation items, the safe driving evaluation threshold value and the sunny day / night mode determination threshold value set from the client information terminal are the communication unit of the on-vehicle device 20. It is wirelessly received through 21 antennas 22.
After the data received by the communication unit 21 is received, the mode determination threshold value is stored in the first storage unit 23, and the safe driving evaluation item and the safe driving evaluation threshold value are stored in the second storage unit 24.

The mode determination threshold value of the driving environment stored in the first storage unit 23 is, for example, a clear rain determination standard or a day / night determination standard, and is a detection value detected by the sensor 26 of the first detection unit 25. The comparison unit (1) 27 performs comparison processing with the wiper operation presence / absence, operation time, time data, etc., so that one mode is changed from the four mode driving environment to the current driving environment. It is judged as.
The selection unit 28 selects a safe driving evaluation threshold corresponding to the traveling environment mode stored in the second storage unit 24 according to the determined traveling environment mode, and the speed provided in the second detection unit 29 By comparing the detected value of the sensor-2a such as a meter with the comparison unit (2) 2b, it is determined which stage of the 5-stage evaluation for each safe driving item.

  If it is judged that the comparison unit (2) 2b is outside the safe driving evaluation threshold range, the fact is recorded in the third storage unit 2d, and the alarm reporting unit 2c responds to the driver according to the stage. A voice alert is issued to reaffirm the awareness of safe driving. Here, although each memory | storage part and each comparison part are described independently for description, you may design so that it may process with memory | storage devices, such as a single memory.

  After the operation is completed, the data stored in the third storage unit 2d is received by the server of the management office by wireless communication from the communication unit 21 via the antenna 22, and is subjected to data processing. A safe driving diagnosis as shown in FIG. In determining the traveling environment, the data of GPS 2e and ETC 2f may be added to the determination material to help determine the traveling road environment such as highway traveling and mountain traveling.

  After the operation is completed, the data transfer method from the vehicle-mounted device to the server may use wireless communication as described above, and preferably a removable storage medium such as HD, flash memory, CF card. -It is also possible to load the data on the in-vehicle device, read the data at the office branch terminal after the operation is completed, and upload it to the server at the office headquarters via LAN etc. . Thereby, it can respond easily by providing the terminal which can read the general purpose memory in the management office branch after operation completion.

In addition, the communication unit 21 transmits data related to vehicle driving and safe driving stored in the third storage unit 2d to the server side at regular intervals, typically every few minutes. The management office can grasp and confirm the safe driving of the vehicle truck without delay.
Further, a server may not be provided for each shipping company, but may be provided in the management headquarters so that vehicle management of a plurality of shipping companies can be performed collectively. Thereby, operation management of a plurality of carriers can be efficiently performed with a single system at a lower cost.

  FIG. 3 shows the system concept of the present invention. The track 30 to be managed includes an in-vehicle device 31 together with the in-vehicle device of the GPS 35. The vehicle-mounted device 31 is configured such that a client who is a cargo owner or a truck manager accesses the host server 34 of the management office via the Internet 33 from the terminal 32 to input the safe driving evaluation. A threshold is transmitted and stored.

  The traveling position of the truck 30 can be confirmed by the GPS 35, and is monitored by a GPS display device together with the map information. On the other hand, the determination threshold set in the vehicle-mounted device 31 has a plurality of modes for each traveling environment such as fine rain and a plurality of levels for each level, and a speedometer, accelerometer, By comparing with information such as inter-vehicle distance meter, time of day, wiper operation status, etc., the optimum selection judgment is made for the current traveling condition of the truck 30 and the surrounding environment condition at the time of traveling, and a sound warning relating to driving guidance is issued. .

Here, a GPS device (Global Positioning System) is a global positioning system, which is a satellite positioning system that can check a current position on the earth using a satellite, and a satellite radio wave receiving antenna. And a map information storage device, a comparison operation device, a display device, and the like.
In addition, as shown in the conceptual diagram of the four modes of fine rainy daytime and nighttime in FIG. 4, the ambient environment conditions are as follows: sunny-daytime 42, sunny-nighttime 44, rainy-daytime 43, -Four modes of night 45 are prepared, and in each mode, safe driving evaluation threshold values for judging the traveling state of the truck such as speed and acceleration are individually set for each stage.

In other words, since driving at nights 44 and 45 and rainy days 43 and 45 is more dangerous, a safe driving evaluation threshold is set on the safe side, and safety is severer than daytime 42 and 43 and sunny weather 42 and 44. The driving evaluation standard is set as a threshold value.
Whether or not it is night driving is set from the client terminal 32 by the night driving definition registration shown in FIG. 5, and is judged day and night by comparing with the time data in the vehicle-mounted device 31 based on the definition.

In the night driving definition registration 50 of FIG. 5, each client has a definition registration screen for the track to be managed, and a night start time 53 and a night end time 54 are input for each month 52. Thereby, the night driving for the track to be managed is set and defined as being from 17:00 to 6:00 in January, for example.
The definition data is set and inputted from the client terminal 32 to the host server 34 of the management office via the Internet 33, and then transmitted to the corresponding track 30 and set in the vehicle-mounted device 31.

The two factors of the state of day and night 41 and the state of clear rain 40 shown in FIG. 4 are typical examples of the ambient environment state. However, the ambient environment condition of the position where the vehicle is traveling is the weather condition, season, time The mode may be increased so as to include the traveling road environment such as a highway or a general road, a bad road or a paved road as a determination target.
The first detection device capable of detecting such an ambient environment state is a sensor or the like, and is stored as a wiper-operating switch ON / OFF for judging the rain 40 and a clock for judging the day / night 41. Therefore, it is possible to make a judgment such as day and night 41. The rain 40 can be detected by a raindrop sensor or the like, and the day and night 41 can be detected based on the light and darkness of the truck running environment by using a conlite using a photodiode. In addition, detection means such as an appropriate sensor can be used depending on the surrounding environment to be detected, such as an ETC signal detector, a vibrometer, or GPS data.

By comparing the driving environment mode judgment threshold set for the track 30 with the sensor detection value by the first detection means, it is possible to determine which of the four modes 42, 43, 44, 45 shown in FIG. Are selected, and a corresponding mode evaluation threshold is selected from the safe driving evaluation threshold set in the vehicle-mounted device 31 according to the mode.
As shown in the safe driving radar chart of FIG. 6, the safe driving evaluation items 62 include a maximum speed, a sudden start, a sudden acceleration, and the like. For each of the four modes 42, 43, 44, 45, It is set at the terminal 32 of the client, communicated and set to the vehicle-mounted device 31 via the host server 34 of the management office.

  FIG. 8 shows a safe driving reference value 80, which is a safe driving evaluation threshold and items set by the client information terminal. Here, each item 82 is ranked 84 in one to five stages, and the reference value 83, which is a safe driving evaluation threshold, is divided into daytime sunny weather 85, daytime rainy weather 86, nighttime sunny weather 87, and nighttime rainy weather 88. 84 is set for each stage. Further, a score of 89, an evaluation 8a, and a comment 8b can be set for each rank 84, and this becomes basic data for forming a safe driving diagnosis table.

For example, in the item of the maximum speed (general), in the daytime clear sky 85, it is 50km / h, comment 8b of "Safe driving", evaluation 8a is "A", score 89 is "20 points", rank 84 is "3" However, in the case of night rain 88, the same rank “3” is obtained at 40 km / h.
Even in sunny day 85, at 90km / h, the rank 84 is “5”, the rating 8a is “E”, the score 89 is “0”, and the comment 8b is “dangerous because of too much speed”. "

  The safe driving evaluation item is compared with the threshold value and the detected driving state of the vehicle, but the maximum speed on the highway from the start of driving, the maximum speed on the general road, the average speed on the highway, the general road Average speed, number of sudden starts / accelerations, number of sudden decelerations, continuous travel time, speed overtime on ordinary roads, speed overtime on highways, and an alarm on the distance between vehicles ahead The number of reports and the like, which is an item 82 for managing safe driving in the traveling state of the vehicle, is appropriately selected and set.

  Further, as shown in FIG. 8, the safe driving evaluation threshold values are the maximum speed (general), the maximum speed (high speed), the average speed (general), the average speed (high speed), the number of sudden starts and accelerations, the number of sudden decelerations, and continuous running. The vehicle driving conditions related to safe driving management items such as time, speed overtime, and numerical values are set in a five-step evaluation for each driving environment condition of daytime sunny weather, daytime rainy weather, nighttime sunny weather, and nighttime rainy weather. Designed to be able to.

Further, these items 82 for evaluating safe driving can be appropriately selected from the terminal 32 for input on the client side. In other words, by selecting the safe driving evaluation items individually according to the characteristics of the vehicle and the vehicle, such as the old and new vehicles, large and medium-sized, small, running area, and running time, a flexible evaluation according to the stage is made. Is possible.
Further, not only the safe driving evaluation items but also the determination threshold value and the mode determination threshold value that are the reference values for the safe driving evaluation are set in advance in the in-vehicle device 31 or through communication means such as a wireless LAN as predetermined determination threshold values. And compared with the value detected by the first detection device or the second detection device. This determination threshold can be set for any single or multiple vehicle units, such as for each vehicle or for each vehicle driver, for each sales office or for each region. Modes are prepared according to the stage.

In addition, safe driving evaluations are assigned from A to E according to each stage, and it is possible to set the evaluation score given for each evaluation. Furthermore, by inputting a comment in accordance with each stage, it is possible to define a comment content or the like for voice warning to the driver during traveling.
In the example shown in FIG. 8, for example, the maximum speed on a general road is 80 km / h or higher in daytime clear weather, the safety driving evaluation of evaluation E is the lowest, and the evaluation score given is 0. The comment at this time is defined as “It is dangerous because the speed is too high”, so if a speed of 80 km / h or more is detected on a general road during sunny daytime, this comment will alert the driver. It is reported.

On the other hand, even if the evaluation score is 0, it is set to correspond to 70 km / h or higher in daytime rainy weather or fine weather at night, and is set to correspond to this in 60 km / h or higher in night rainy weather. Yes. Of course, this set value can be set for each driver or for each vehicle.
This set value can be entered as a determination threshold value by accessing the host server 34 from the client terminal 32 personal computer via the Internet 33 via the Internet 33, and can be input from a distance, but it is an information terminal on the client side. The terminal 32 is an electronic arithmetic device such as a personal computer, a server, a workstation, a handy terminal, a mobile phone, a notebook personal computer, and the like. Since the barriers are disappearing, any information terminal device that can input / output, transmit / receive, store, store, and perform predetermined information, or a combination thereof may be used.

  The determination threshold value input from the terminal 32 is transmitted from the host server 34 to the traveling truck 30 by packet communication or the like. In each vehicle, the on-vehicle device 31 having a receiving device receives and sets and stores it in the storage device, and the vehicle running conditions that change from moment to moment, such as speedometer data during running and running environment data in fine rain While monitoring the vehicle driving environment condition, the driving situation is determined by comparing with the threshold value stored and stored, and an appropriate comment is given to the driver in real time.

In other words, regardless of certain uniform conditions, the optimum safe driving judgment criteria can be flexibly selected according to the environmental conditions that change from moment to moment, such as fine rain and day and night. Will be emitted.
Here, the receiving device of the vehicle-mounted device 31 used may be a satellite signal receiving device or the like in addition to a wireless receiving method including packet communication using a PHS or a mobile phone, and the transmitted information may be a radio wave, an optical signal, Any device can be used as long as it can receive a sound signal or the like.

Further, although the clear rain judgment is made based on whether or not the wiper is in operation, in this embodiment, the clear sky judgment is “sunny” 5 minutes after the wiper switch is turned off, and “rain” is 1 minute after the wiper switch is turned on. It was possible to perform good operation by setting the
This value is obtained statistically and empirically in consideration of the movement of rain clouds and the moving speed of the vehicle, but can be appropriately set according to the driver and vehicle characteristics.

Further, the determination of day and night can be set in advance on the client terminal side for each month as shown in FIG. Since the night start time and the night end time vary depending on the season and also on a monthly basis depending on the location, they are set on a monthly basis.
This determination threshold is also set at the client terminal, transmitted from the host server to the traveling vehicle via the Internet, and compared with the data of the clock mounted on the vehicle, and is determined day and night. Thus, a safe driving diagnosis threshold (such as a maximum speed) that is a safe driving management standard is individually selected.

In addition to this, the day / night judgment may be based on a light sensor or in conjunction with a headlight or positioning light. In this case, the night mode requires a more rigorous awareness of safe driving in daytime or in dimly lit clouds. Therefore, it is preferable because a safe driving standard for night mode can be applied after judgment.
The determination threshold and the detection value are stored in the storage device and used for safe driving evaluation after the operation is completed.
This storage device may be any device that can input and hold necessary information such as ROM, DVD-RW, CD-RW, MO, HD, and other flash memory, and can read it out as necessary. Moreover, since it will improve utility if it is detachable, it is preferable.

  Next, the safe driving evaluation after the vehicle travel is completed will be described. The data of the vehicle traveling state and the vehicle traveling environment accumulated during traveling are transferred from the vehicle terminal to the information processing terminal (server, etc.) after the traveling is completed, and the safe driving radar as shown in FIG. Create chart 62. In this safe driving radar chart 62, each of the safety driving evaluation items is represented by a five-level evaluation from A to E, and it is possible to clearly grasp the excess or deficiency of the safe driving characteristics in a series of driving of the driver and give it. A comprehensive evaluation 63 from A to E is given by the comprehensive evaluation point obtained by adding the respective evaluation points, and a safe driving diagnosis 61 is performed.

Further, as shown in FIG. 7, for each safe driving evaluation item 72 subjected to statistical processing, a comment 76 linked with the evaluation 75 of A to E is given, and the improvement of the driver's safety driving awareness and the reflection of past driving are given. It helps to recognize the strengths and deficiencies of your own safe driving skills and use them for improvement.
For example, in the item of the number of rapid decelerations 77 in FIG. 7, the actual measurement value 73 is “1”, the score 74 is “100”, the evaluation 75 is “A”, and the comment 76 is “your smooth”. Driving is excellent ”is displayed.

In addition to this embodiment, by detecting snowy roads and frozen road surfaces in conjunction with ABS (anti-lock brake system) as conditions for the surrounding environment of the vehicle, safe driving management for snowy roads and frozen road surfaces A value may be set and advice for snow roads etc. may be issued and instructed.
The second detection device is a means for detecting the running state of the vehicle, and a speedometer, an accelerometer, a computing device, a storage device, an inter-vehicle distance meter, etc. are used as appropriate. Depending on the object, other suitable sensors may be used.

  The network referred to in the present invention is typically a global network based on the Internet, but is used between group companies such as a wireless LAN and a wired LAN, and between offices. It may be a closed network. Preferably, it is easier to manage security if the network is managed by ID, password, etc., and its use and login access are restricted to a specific person. It is safe.

The ability to set a safe driving evaluation threshold for each vehicle from a remote site via the network is not limited to the carrier that manages and manages the vehicle and safe driving evaluation diagnosis, for example, It is also preferable for the cargo owner himself to manage the details finely and accurately.
Further, the safe driving reference value referred to in the present invention is typically a score in, for example, a five-step evaluation for each safe driving evaluation item such as maximum speed (general, high speed), average speed, number of sudden starts, number of sudden accelerations, etc. It is also associated with driving index comments at each evaluation stage.

This judgment element has a mode of each driving environment according to various driving environments, and in particular, a four-pattern mode (day-sunny, day-rain, night-sunny, (Night-Rain) is preferable because it enables appropriate evaluation according to more detailed driving environment conditions.
In addition, the judgment threshold set on a monthly basis depending on the season is different from the length and time of day and night depending on the season. Sets the time.

In addition, since the length and time of day and night are different in regions where the latitude is different from the determination threshold set according to the region, it is preferable that it can be set for each certain region such as a narrower sales office region or each latitude region. .
In addition, wireless communication that can communicate with the outside even during movement such as PHS, mobile phone, satellite communication, and transceiver is used.

Further, when the wiper operation / non-operation is used as a reference signal, the wiper operation / non-operation may be immediately followed, or, for example, after a certain period of time has elapsed since the wiper operation / non-operation detection. It is also possible to emit a trigger.
For example, in the operation management apparatus shown in FIG. 9, an in-vehicle device 92 of an operation management system is mounted on a vehicle 91, and an arithmetic processing device (server or the like) 94 disposed in the management office 93 uses each in-vehicle device 92. The recorded operation management data is aggregated, and the vehicle 91 and business management can be performed.

The in-vehicle device 92 includes a sensor 95 that detects a vehicle state signal such as a vehicle speed, an engine speed, and a direction of the vehicle 91, an input terminal 97 that inputs work contents by a crew member 96, and a storage medium 98 that records these various data. Have In the arithmetic processing unit 94, the operation management data read from the storage medium 98 is analyzed and output.
The output data will be used for proper management of the operation status in order to allow the crew 96 to carry out economic driving and to promote safe driving due to the recent increase in awareness of global environmental protection and fuel cost savings. Therefore, it can be used as a driving history.

Furthermore, a warning device provided in the in-vehicle device 92 can issue a warning for dangerous driving and non-economic driving of the crew member 96. For example, a predetermined threshold is set for the engine speed and vehicle acceleration. By setting or detecting a steep handle or the like, a warning is set when a predetermined threshold is exceeded.
In addition, since highway driving is performed at a higher speed than ordinary road driving, the conditions for proper driving are different, so the highway driving is recognized by input from the crew 96 or GPS position data. It is designed to issue a warning determined at the evaluation threshold set for the expressway mode.
(Second embodiment)
A second embodiment of the present invention will be described with reference to FIG.
The vehicle (truck) 30 includes a wireless communication terminal that can communicate with the vehicle-mounted device 31 and the GPS 35.

  This vehicle-mounted device 31 includes a removable storage medium, and vehicle operation information (time information, wiper operation state information, general road / highway information, actual vehicle / empty vehicle information, vehicle speed information, position information, sudden start related to vehicle operation.・ Sudden acceleration information, sudden deceleration information, overspeed information, inter-vehicle distance abnormality information) is collected and stored in a storage medium in time series. In addition, a part of the vehicle operation information is configured to be transmitted / received to / from the server 34 via the wireless communication terminal.

On the other hand, the office terminal 32 of the transportation company, which is a management company of the vehicle (truck) 30, stores the stored vehicle operation information from the storage medium taken out from the vehicle-mounted device 31 through the storage medium reader after the operation ends. Reading and uploading vehicle operation information to the server 34 via the Internet 33.
The server 34 is set with a threshold value for analyzing the vehicle operation information transmitted from the office terminal 32 or the wireless communication terminal of the vehicle (truck) 30, and performs a safe driving evaluation based on this threshold value.

The threshold of the server 34 can be changed from the office terminal 32 via the Internet 33. A safe driving radar chart, which is a safe driving evaluation result analyzed by the server 34, can be downloaded to the office terminal 32 via the Internet 33.
The office terminal 32 is an information terminal such as a personal computer, and is not limited to one provided in the office, and may be a portable notebook computer or the like.

Next, the vehicle-mounted device 31 according to the second embodiment will be described in detail.
In the vehicle-mounted device block diagram according to the second embodiment shown in FIG. 10, the vehicle speed detecting means 104 for detecting the speed of the vehicle, the wiper operating state detecting means 105 for detecting the operation / non-operation of the wiper, and an abnormality in the inter-vehicle distance are detected. Each detecting means such as an inter-vehicle distance detecting means 106, a position information receiving means 107 for receiving GPS position information, and a wireless communication means 108 for transmitting / receiving information to / from an external device are connected to the CPU 101, respectively.

The vehicle-mounted device 100 includes a general road / highway switching SW 103 for switching whether the vehicle is traveling on a general road or a highway, and an end-of-business button 102 for performing a final work on the storage medium 109, and is connected to the CPU 101. The In addition, the CPU 101 is provided with time measuring means (not shown).
By adopting such a configuration, the vehicle operation information (time information, wiper operating state information, general road / highway information, actual / empty vehicle information, vehicle speed information, position information, sudden start / Acceleration information, sudden deceleration information, inter-vehicle distance abnormality information, speed over information).

The CPU 101 writes the collected vehicle operation information to the recording medium 109 and transmits it to an external server or the like via the wireless communication means 108. In addition, the CPU 101 performs transmission / reception of information with a server or the like via the wireless communication unit 108, and performs start-up processing and end-of-work processing to the storage medium 109.
Further, the storage processing in the storage medium 109 by the CPU 101 is as follows.
The CPU 101 determines a wiper operating state determination time (for example, 1 minute) for determining that the wiper is in an operating state, and a wiper non-operating state determination time (for example, 3 minutes) for determining that the wiper is inactive. When the change of the wiper operation switch from ON to OFF and OFF to ON is detected by the wiper-operating state detection means 105, the time after the change is measured is measured. It is determined whether or not the stored determination time of each operating state has been exceeded.

When the determination time is exceeded, it is determined that the wiper has been switched from the operating state to the non-operating state or from the non-operating state to the operating state. By providing the stored determination time, even when the wiper is temporarily switched to the non-operating state, it is possible to improve the reliability of the determination without making an erroneous rain detection.
Further, the CPU 101 stores, for example, “3.5 m / s ² ” as a sudden start / rapid acceleration threshold for detecting sudden start / rapid acceleration, and vehicle speed information and timing means by the vehicle speed detecting means 104 are stored. When the acceleration obtained from the time information or the travel distance by the vehicle exceeds the sudden start / rapid acceleration threshold, it is determined that the vehicle is suddenly started / accelerated, and the sudden start / accelerated acceleration information is stored in the storage medium 109.

Further, the CPU 101 stores, for example, “4.0 m / s ² ” as a rapid deceleration threshold for detecting that the vehicle is suddenly decelerated. The vehicle speed information by the vehicle speed detecting unit 104, the time information by the time measuring unit, and the travel distance are stored. When the deceleration obtained from the above becomes equal to or greater than the rapid deceleration threshold, it is determined that the deceleration is rapid, and the rapid deceleration information is stored in the storage medium 109.
Further, the CPU 101 stores, for example, a threshold as a function of the vehicle speed such as “when the vehicle speed is 70 km / h or more and the inter-vehicle distance is within 70 m” as the inter-vehicle distance abnormality threshold for detecting that the inter-vehicle distance is abnormal. If the detected inter-vehicle distance at the vehicle speed exceeds the inter-vehicle distance abnormality threshold based on the detected vehicle speed from the vehicle speed detecting means 104, it is determined that the inter-vehicle distance is abnormal and is stored in the storage medium 109.

The CPU 101 stores, for example, “the vehicle speed is 60 km / h for a general road and 80 km / h for a highway” as a speed over threshold for detecting that the vehicle is overspeed, and the vehicle speed detected by the vehicle speed detection unit 104 is stored. Is over the speed over threshold value, it is determined that the speed is over, and is stored in the storage medium 109.
Further, the wiper operation state determination time, wiper non-operation state determination time, sudden start / rapid acceleration threshold, sudden deceleration threshold, inter-vehicle distance abnormality threshold, and speed over threshold stored in the CPU 101 are changed in the in-vehicle device 100. By providing the means, the threshold can be changed from the vehicle-mounted device 100 or from an external information terminal.

The threshold can be changed at a time when the setting can be changed while driving. Preferably, the new threshold becomes effective after the next operation, that is, after the next latest start-up process is performed. It is set as the structure set so that it may become.
Further, by providing the vehicle-mounted device 100 with a voice guide means, at least one of a wiper operation state determination time, a wiper non-operation state determination time, a sudden start / rapid acceleration threshold, a sudden deceleration threshold, an inter-vehicle distance abnormality threshold, and a speed over threshold If the threshold value is exceeded, voice guidance may be performed in the driver's cab by this voice guidance means.

  In addition, after the operation ends, the data transfer method from the vehicle-mounted device 100 to the server reads information from the HD, flash memory, CF card, etc., which is the removable storage medium 109 as described above, office terminal, etc. Uploading to a server via the Internet, or by providing wireless communication means capable of communicating with the outside even when the vehicle is moving, such as PHS, mobile phone, satellite communication, etc. It may be configured to be able to transmit data to the bar.

Moreover, the mode determination means 111 reads the mode determination threshold value memorize | stored in the mode determination threshold value memory | storage means 115, compares and processes vehicle operation information about each mode like FIG. 13, and makes it vehicle operation processing information.

The safe driving evaluation threshold value storage means 116 stores the safe driving evaluation threshold value of each mode corresponding to each selected mode for each safe driving evaluation item. The comparison unit 112 compares the safe driving evaluation threshold corresponding to each selected mode with the vehicle operation processing information obtained by processing the vehicle operation information according to the vehicle operation information and / or the safe driving evaluation item.
The threshold setting unit 117 sets or changes the mode determination threshold and the safe driving evaluation threshold stored in the mode determination threshold storage unit 115 and the safe driving evaluation threshold storage unit 116.

The mode determination threshold value includes time information for determining day and night in the present embodiment, and wiper operation state information for determining fine rain.

Next, it is determined whether or not the closing button 102 has been pressed (step 124). If it is determined that the end button 102 has not been pressed, step 123 is repeated. If it is determined that the end-of-business button has been pressed, the process proceeds to step 125 and the end-of-business process is performed on the storage medium 109.
Then, the storage medium 109 that has been subjected to the end-of-work process after the operation of the vehicle is removed from the vehicle-mounted device 100 and connected to the office terminal 32. The office terminal 32 reads the vehicle operation information from the storage medium 109 via the storage medium reading device, and uploads the vehicle operation information to the server 34 that is a safe driving evaluation device via the Internet 33.

Next, analysis processing relating to processing of vehicle operation information performed in the server 34 will be described below with reference to a server processing flowchart according to the second embodiment shown in FIG.
The vehicle operation information uploaded to the server 34 via the communication unit 110 is sent to the mode determination unit 111 (step 130).
Next, the vehicle operation information of each mode (daytime / sunny mode, daytime / rainy mode, night / sunny mode, night / rainy mode) is processed into information corresponding to the safe driving evaluation threshold. Then, the maximum speed of the general road in each mode is analyzed from the time information, the wiper operating state information, the vehicle speed information, and the general road / highway information (step 131a).

Further, the time information, wiper operation state information, and maximum speed of the highway in each mode are analyzed from the time information, wiper operation state information, vehicle speed information, and general road / highway information (step 131b).

Comprehensive evaluation is analyzed from the results analyzed in steps 131a to 131j (step 132).

Here, the continuous running time is the longest time among times when the vehicle speed is not zero continuously in time series, but the time when the vehicle speed continuous in time series is zero is a predetermined period (for example, 5 If it is less than (min), it is regarded as running and counted as continuous running time. Thereby, a temporary stop such as waiting for a signal or traffic jam can be regarded as traveling.
The comprehensive evaluation is a comprehensive evaluation based on the results of the five-step evaluation in steps 131a to 131j. As an evaluation method, for example, the evaluation is performed using the score 74, the evaluation 75, or the like in FIG.

  The vehicle operation information is processed for comparison with the safety evaluation threshold value stored in the safe driving evaluation threshold value storage means 116. The vehicle operation information collected by the vehicle-mounted device 100 is used as the office terminal 32 or the like. As information that can be compared with the safety evaluation threshold value in advance, for example, if it is processed into the maximum speed, average speed, etc. on a general road, the mode determination unit 111 only needs to perform mode determination on the processed information.

  Next, it is stored in the vehicle operation processing information and the safe driving evaluation threshold value storage means 116 for each mode (daytime / sunny mode, daytime / rainy mode, night / sunny mode, night / rainy mode) analyzed in steps 131a to 132. Safety driving evaluation thresholds (highway maximum speed threshold, highway maximum speed threshold, general road average speed threshold, highway average speed threshold, sudden start / acceleration count threshold, sudden deceleration count threshold, continuous travel time threshold, general road The speed over time ratio threshold, the expressway speed over time ratio threshold, the inter-vehicle distance abnormality frequency threshold, and the overall evaluation threshold) are compared, and a five-level evaluation is performed as described below.

That is, the vehicle operation processing information processed by the mode determination unit 111 is sent to the comparison unit 112. Then, in the evaluation flow chart of the comparison means 112 shown in FIG. 14, it is determined by comparing to which of the five stages the maximum speed of the general road in each mode belongs (step 140a).
It is determined by comparing to which of the five stages the maximum speed of the highway in each mode belongs (step 140b).

It is determined by comparing which of the five stages the speed over time ratio of the highway in each mode belongs (step 140f). A determination is made by comparing which of the five stages the continuous running time belongs to in each mode (step 140g).
It is determined by comparing which of the five stages the average number of sudden decelerations per hour in each mode belongs (step 140h). It is determined by comparing which of the five stages the average number of sudden starts / accelerations per hour in each mode belongs (step 140i). It is determined by comparing which of the five stages the number of abnormal distances between the vehicles in each mode belongs (step 140j).

It is determined by comparing which of the five stages the comprehensive evaluation threshold value in each mode belongs (step 140k). The comparison result storage unit 113 stores the information compared in steps 131a to 132 and steps 141a to 141k.
The comparison result is compared with the safe driving evaluation item, the safe driving evaluation threshold value, and the sunny day / night mode determination threshold value, and the determined information is stored in the comparison result storage unit 113. Then, the safe driving evaluation radar chart shown in FIGS. 6 and 7 is created by the creation unit 114, and can be downloaded to the office terminal 32 via the communication unit 110.

The comparison means 112 creates steps 140a to 140k and a safe driving evaluation radar chart, and stores information such as a safe driving evaluation radar chart that can be downloaded to the office terminal 32 in the comparison result storage means 113. May be.
In the threshold value setting flowchart according to the second embodiment of the present invention shown in FIG. 15, the administrator who manages the vehicle uses the office terminal 32 connected to the Internet 33 installed in the office to use the server 34. The mode determination threshold and the safe driving evaluation threshold set in the server 34 can be changed by accessing.

Hereinafter, the change of the threshold value in the server 34 will be described with reference to FIG.
First, it is determined whether there is information for changing the threshold (step 150). If it is determined that there is information for changing the threshold value, the process proceeds to step 151; otherwise, step 150 is repeated. In step 151, it is determined whether the information for changing the threshold value is a mode determination threshold value.

  If it is determined that the information for changing the threshold is the mode determination threshold, the process proceeds to step 153. If the information for changing the threshold is not determined to be the mode determination threshold, the process proceeds to step 152. In step 152, if there is change information on the mode determination threshold, the setting of the mode determination threshold (threshold for which a change request has been made among day / night determination threshold and clear rain determination threshold) stored in the mode determination threshold storage unit 115 is changed. (Step 153).

  When there is no change information of the safe driving evaluation threshold value in step 152, the process proceeds to the end. If there is change information of the safe driving evaluation threshold value in step 152, the safe driving evaluation threshold value stored in the safe driving evaluation threshold value storage means 116 (maximum speed on general road, maximum speed on highway, Average speed, average speed on highway, number of sudden starts / accelerations per hour, number of rapid decelerations per hour, continuous running time, speed overtime ratio per hour on ordinary roads, on highway The setting of the speed over time ratio per hour, the number of abnormal distances between the vehicles, and the threshold value requested to be changed among the comprehensive evaluations is changed (step 154).

Further, as shown in FIG. 4 as a conceptual diagram of four modes of fine rainy daytime and nighttime, the vehicle surrounding environment conditions are as follows. 43 and rainy-nighttime 45 modes are prepared, and in each mode, safe driving evaluation thresholds for judging the running state of the vehicle such as speed and acceleration are individually set for each stage. .
In other words, since driving at nights 44 and 45 and rainy days 43 and 45 is more dangerous, a safe driving evaluation threshold is set on the safe side, and safety is severer than daytime 42 and 43 and sunny weather 42 and 44. The driving evaluation standard is set as a threshold value.

Whether it is night driving is set from the office information terminal 32 by night driving definition registration shown in FIG. 5, and is judged day and night by comparing with time information of vehicle operation information based on the definition.
In the night driving definition registration 50 in FIG. 5, the company that manages the vehicle has a definition registration screen for the vehicle to be managed, and inputs a night start time 53 and a night end time 54 for each month 52. Thereby, the night driving for the management target vehicle is set and defined as being between 17:00 and 6:00 in January, for example.

  This definition data is set in the server 34 from the office terminal 32 via the Internet 33. The two factors of the state of day and night 41 and the state of clear rain 40 shown in FIG. 4 are typical examples of the ambient environment state. However, the ambient environment condition of the position where the vehicle is traveling is the weather condition, season, time The mode may be increased so as to include the traveling road environment such as a highway or a general road, a bad road or a paved road as a determination target.

As shown in the safe driving radar chart of FIG. 6, the safe driving evaluation items 62 include a maximum speed, a sudden start, a sudden acceleration, and the like. For each of the four modes 42, 43, 44, 45, It is set at the office terminal 32, communicated to the server 34, and set.
FIG. 8 shows a safe driving reference value 80, which is a safe driving evaluation threshold and items set by the client information terminal. Here, each item 82 is ranked 84 in 1 to 5 stages, and the reference value 83 which is a safe driving evaluation threshold is divided into fine weather-daytime 85, fine weather-rainy weather 86, nighttime-fine weather 87, and nighttime-rainy weather 88. Are set for each stage according to rank 84. Further, a score of 89, an evaluation 8a, and a comment 8b can be set for each rank 84, and this becomes basic data for forming a safe driving diagnosis table.

For example, in the item of the maximum speed (general), in the daytime clear sky 85, it is 50km / h, comment 8b of "Safe driving", evaluation 8a is "A", score 89 is "20 points", rank 84 is "3" However, in the case of night rain 88, the same rank “3” is obtained at 40 km / h.
Even in sunny day 85, at 90km / h, the rank 84 is “5”, the rating 8a is “E”, the score 89 is “0”, and the comment 8b is “dangerous because of too much speed”. "

  The safe driving evaluation item is compared with the threshold value and the detected driving state of the vehicle, but the maximum speed on the highway from the start of driving, the maximum speed on the general road, the average speed on the highway, the general road Average speed, number of sudden starts / accelerations, number of sudden decelerations, continuous travel time, speed overtime on ordinary roads, speed overtime on highways, and an alarm on the distance between vehicles ahead The number of reports and the like, which is an item 82 for managing safe driving in the traveling state of the vehicle, is appropriately selected and set.

  Further, as shown in FIG. 8, the safe driving evaluation threshold values are the maximum speed (general), the maximum speed (high speed), the average speed (general), the average speed (high speed), the number of sudden starts and accelerations, the number of sudden decelerations, and continuous running. The vehicle driving conditions related to safe driving management items such as time, speed overtime, and numerical values are set in a five-step evaluation for each driving environment condition of daytime sunny weather, daytime rainy weather, nighttime sunny weather, and nighttime rainy weather. Designed to be able to.

Furthermore, the items 82 for evaluating the safe driving can be appropriately selected from the office terminal 32. In other words, by selecting the safe driving evaluation items individually according to the vehicle type, large-sized, medium-sized, small-sized, traveling area, traveling time, etc., which are the characteristics of the driver and the truck 30, a flexible evaluation according to the stage is made. Is possible.
Further, not only the safe driving evaluation items, but also the determination threshold value and the mode determination threshold value that are the reference values for the safe driving evaluation are set as predetermined determination threshold values in advance in the server 34 or via communication means such as a wireless LAN. Is set. This determination threshold value can be set for any single or multiple vehicle units such as for each vehicle, for each driver, for each sales office, for each region, etc., and for a plurality of modes depending on the vehicle driving environment such as weather. -Does are prepared according to the stage.

In addition, safe driving evaluations are assigned from A to E according to each stage, and it is possible to set the evaluation score given for each evaluation. Furthermore, by inputting a comment according to each stage, it is displayed in the comment 76 of FIG.
On the other hand, even if the evaluation score is 0, it is set to correspond to 70 km / h or higher in daytime rainy weather or fine weather at night, and is set to correspond to this in 60 km / h or higher in night rainy weather. Yes. Of course, this set value can be set for each driver or for each vehicle.

  This set value can be entered as a determination threshold value from the remote terminal by accessing the server 34 from the office terminal 32 personal computer via the Internet 33. Is an electronic computing device such as a personal computer, server, workstation, handy terminal, mobile phone, notebook personal computer, etc. Since the barrier is disappearing, any information terminal device that can input / output, transmit / receive, store, store, and perform predetermined information, or a combination thereof may be used.

In addition, the clear rain judgment is performed based on whether or not the wiper is operated. In this embodiment, the clear sky judgment is “sunny” 5 minutes after the wiper switch is turned off, and “rain” is 1 minute after the wiper switch is turned on. It was possible to perform good operation by setting the
This value is obtained statistically and empirically in consideration of the movement of rain clouds and the moving speed of the vehicle, but can be appropriately set according to the driver and vehicle characteristics.

Further, the determination of day and night can be set in advance on the terminal 32 side for each month as shown in FIG. Since the night start time and the night end time vary depending on the season and also on a monthly basis depending on the location, they are set on a monthly basis.
This determination threshold is also set by the client terminal, and then transmitted from the server 34 to the traveling vehicle via the Internet.

In addition to this, the day / night judgment may be based on a light sensor or in conjunction with a headlight or positioning light. In this case, the night mode requires a more rigorous awareness of safe driving in daytime or in dimly lit clouds. Therefore, it is preferable because a safe driving standard for night mode can be applied after judgment.
Next, the safe driving evaluation after the vehicle travel is completed will be described. As shown in FIG. 6, the safe driving radar chart 62 obtained from the vehicle operation information is represented by a five-step evaluation from A to E for each safe driving evaluation item, and the safe driving in a series of driving of the driver. Whether the characteristic is excessive or insufficient can be grasped at a glance, and a comprehensive evaluation 63 from A to E is given by a comprehensive evaluation point including the given evaluation points, and a safe driving diagnosis 61 is performed.

Further, as shown in FIG. 7, for each safe driving evaluation item 72 subjected to statistical processing, a comment 76 linked with the evaluation 75 of A to E is given, and the improvement of the driver's safety driving awareness and the reflection of past driving are given. Encourage them to recognize the advantages and disadvantages of their safe driving skills and use them for improvement.
For example, in the item of the number of rapid decelerations 77 in FIG. 7, the actual measurement value 73 is “1”, the score 74 is “100”, the evaluation 75 is “A”, and the comment 76 is “your smooth”. Driving is excellent ”is displayed.

In addition to this embodiment, by detecting snowy roads and frozen road surfaces in conjunction with ABS (anti-lock brake system) as conditions for the surrounding environment of the vehicle, safe driving management for snowy roads and frozen road surfaces A value may be set and advice for snow roads etc. may be issued and instructed.
The network referred to in the present invention is typically a global network based on the Internet, but is used between group companies such as a wireless LAN and a wired LAN, and between offices. It may be a closed network. Preferably, it is easier to manage security if the network is managed by ID, password, etc., and its use and login access are restricted to a specific person. It is safe.

The ability to set a safe driving evaluation threshold for each vehicle from a remote site via the network is not limited to the carrier that manages and manages the vehicle and safe driving evaluation diagnosis, for example, It is also preferable for the cargo owner himself to manage the details finely and accurately.
Further, the safe driving reference value referred to in the present invention is typically a score in, for example, a five-step evaluation for each safe driving evaluation item such as maximum speed (general, high speed), average speed, number of sudden starts, number of sudden accelerations, etc. It is also associated with driving index comments at each evaluation stage.
