The present invention relates to an engine output control device capable of operating an engine with engine output, an engine output control method, and an engine output control program.

  Conventionally, there has been disclosed an example of control for limiting engine output when a brake pedal and an accelerator pedal are operated simultaneously in an automobile.

  For example, in Patent Document 1, in a vehicle equipped with an automatic transmission, the brake and the accelerator are intentionally operated simultaneously on the basis of information indicating the state of the brake operation, information on the speed of the vehicle, and information on the accelerator opening. Throttle control that adjusts the throttle opening so that the engine speed becomes a speed that does not give a load to the drive system of the vehicle when it is determined whether or not it is in a stalled state.

Japanese Patent Laid-Open No. 11-182274 (paragraphs 0007-0010, FIG. 1) Japanese Utility Model Publication No. 64-47439 (page 3-6, Fig. 1)

  By the way, in a vehicle equipped with a manual transmission, for example, when traveling on a circuit course, the driver is decelerating by operating a brake pedal in order to reduce the speed of the vehicle before the circuit course curve. When exiting a curve, in order to obtain an appropriate driving force from the engine, it is necessary to operate the shift lever to switch to a gear suitable for the speed at the time of exiting the curve.

  At this time, in order to ensure the running stability of the vehicle, the operator operates the accelerator pedal with the heel of the right foot while operating the brake pedal with the toe of the right foot to decelerate the vehicle and adjusts the engine speed. There is a case where a so-called heel and toe operation is performed in which the speed is increased to a predetermined rotational speed at which no impact is caused by the speed change. To explain the procedure of this heel and toe operation,

(A1) Operate the clutch pedal to disengage the clutch.
(A2) The accelerator pedal is operated to match the engine speed corresponding to the vehicle speed of the gear desired to be changed.
(A3) The shift lever is operated to shift to a desired gear.
(A4) Operate the clutch pedal to engage the clutch.
The above procedure (a1) to procedure (a4) are performed while operating the brake pedal and decelerating the vehicle.

  Also, for the same purpose as the heel and toe operation, the operator must engage the clutch in the neutral position during deceleration and synchronize the rotation speed of the main shaft inside the manual transmission with the rotation speed of the engine. Thus, there is a case where a so-called double clutch operation is performed to suppress an impact caused by a shift. The procedure of this double clutch operation is explained as follows:

(B1) Operate the clutch pedal to disengage the clutch.
(B2) Operate the shift lever to set the manual transmission to the neutral position.
(B3) The clutch pedal is operated to engage the clutch.
(B4) The accelerator pedal is operated to match the engine speed corresponding to the vehicle speed of the gear desired to be changed.
(B5) Operate the clutch pedal to disengage the clutch.
(B6) Operate the shift lever to shift to the desired gear.
(B7) The clutch pedal is operated to engage the clutch.
The above procedure (b1) to procedure (b7) are performed while operating the brake pedal and decelerating the vehicle.

  However, when the engine output control means described in Patent Document 1 or Patent Document 2 is applied to a vehicle equipped with a manual transmission, if the heel and toe operation or the double clutch operation described above is performed on a circuit course or the like, In step (a2) and step (b4), since the accelerator pedal and the brake pedal are operated simultaneously, the engine output is limited, and the engine speed cannot be increased to a desired value. This causes a problem that the heel and toe operation and the double clutch operation cannot be performed.

  Accordingly, an object of the present invention is to provide an accelerator pedal and a brake under a predetermined condition in a vehicle with a manual transmission having an engine output control means for limiting engine output when the accelerator pedal and the brake pedal are operated simultaneously. It is to provide an engine output control means capable of increasing the engine output when the pedal is operated simultaneously.

Then, this predetermined output is increased.

  According to the first aspect of the present invention, when the accelerator pedal and the brake pedal are operated at the same time, when the operation amount of the clutch is detected, the engine output is increased. The engine output can be increased to the engine speed desired by the operator, and when the amount of clutch operation is not detected, the output of the engine is limited and the influence on the braking force can be suppressed. Consumption can be suppressed.

  Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(First embodiment)
The first embodiment of the present invention is provided with a manual transmission, and in a vehicle having engine output control means for limiting engine output when the accelerator pedal and the clutch pedal are operated simultaneously, for example, when a heel and toe operation is performed Furthermore, in order to operate the engine up to a desired engine speed, the engine output control is performed based on the operation amount of the clutch pedal.

  In the present embodiment, a sensor for detecting the operation amount of each pedal is installed in an accelerator pedal, a brake pedal, and a clutch pedal of a vehicle having a manual transmission (not shown), and the accelerator pedal, the brake pedal, Hereinafter, the operation amounts detected by the sensors installed on the clutch pedal are referred to as an accelerator operation amount Ac, a brake operation amount Br, and a clutch operation amount Cl, respectively. In this embodiment, engine output control is performed by adjusting a throttle valve control signal Sv that is a throttle valve control signal.

FIG. 1 is an example of a functional block diagram of the engine output control device of the present embodiment. The configuration and function of the engine output control device 1 will be described in detail with reference to FIG.
The engine output control device 1 according to this embodiment is mainly composed of a throttle control unit 2, a driving operation detection unit 3, and a throttle characteristic map 4. Next, each component of the engine output control device 1 will be described.

The throttle control unit 2 has a throttle control function that calculates the throttle opening degree Th according to the accelerator operation amount Ac by a predetermined algorithm and outputs a throttle valve control signal Sv to a throttle valve (not shown). Further, when the throttle control unit 2 obtains a predetermined signal from the driving operation detection unit 3, the throttle control unit 2 refers to the throttle characteristic map 4 and performs a throttle operation within the range of the maximum throttle opening degree Th _MAX corresponding to the brake operation amount Br. Control is performed to calculate the opening degree Th and output a throttle valve control signal Sv corresponding to the throttle opening degree Th to the throttle valve.

  When the accelerator operation amount Ac and the brake operation amount Br are detected at the same time, the driving operation detection unit 3 determines whether or not a predetermined clutch operation amount Cl has been detected, and provides information indicating the result to the throttle control unit 2. Output to.

The throttle characteristic map 4 is table data in which a correspondence relationship between the brake operation amount Br and the maximum throttle opening degree Th _MAX is recorded. Here, FIG. 2 is an example of the throttle characteristic map 4. As shown in FIG. 2, the throttle characteristic map 4 records a first throttle characteristic indicated by reference numeral 5 and a second throttle characteristic indicated by reference numeral 6. Here, the first throttle characteristic has a characteristic that the maximum throttle opening degree Th _MAX is suppressed with respect to the same brake operation amount Br as compared with the second throttle characteristic. For example, as shown in FIG. 2, when the brake operation amount Br is “B1”, “T1”, which is the maximum throttle opening Th _MAX in the first throttle characteristic, is the maximum throttle opening in the second throttle characteristic. It can be seen that the value is lower than 'T2' which is Th _MAX . 'T3' is the maximum value of the stall opening, and the second throttle characteristic is set between the first throttle characteristic and a straight line drawn horizontally from 'T3' shown by the broken line in FIG. The

  The engine output control apparatus 1 according to the present embodiment includes an engine stored in a ROM in a computer having a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an input / output interface, and the like. The throttle control map 4 is stored in the ROM, which is realized by developing and executing the output control program in the RAM.

  Next, the operation of the engine output control device 1 will be described with reference to the flowchart shown in FIG.

  First, in order to determine whether or not the accelerator pedal and the brake pedal are operated simultaneously, the driving operation detection unit 3 determines whether or not the accelerator operation amount Ac and the brake operation amount Br are detected simultaneously (step S101). . Here, the detection of the accelerator operation amount Ac and the brake operation amount Br is determined when each operation amount exceeds a predetermined threshold value, and this threshold value can be arbitrarily set.

  Here, when it is determined that the accelerator pedal and the brake pedal are not operated simultaneously (in the case of “No” in step S101), the driving operation detection unit 3 detects the accelerator operation amount Ac and the brake operation amount Br simultaneously. First operation detection information indicating that there has been no transmission is transmitted to the throttle control unit 2 (step S102). The throttle control unit 2 that has acquired the first operation detection information calculates the throttle opening degree Th based on the accelerator operation amount Ac by a predetermined algorithm (step S103), and performs throttle valve control according to the throttle opening degree Th. The signal Sv is output to the throttle valve (step S104).

  Next, when it is determined that the accelerator pedal and the brake pedal are operated at the same time (in the case of “Yes” in step S101), the driving operation detector 3 determines whether or not the clutch pedal has been operated. It is determined whether the operation amount Cl is equal to or greater than a predetermined threshold (step S105). In this determination, even if the clutch operation amount Cl when the clutch pedal is fully depressed is set to “1” and the clutch operation amount Cl is set to “1”, for example, the clutch operation amount Cl is “0.6”. The half-clutch state can be used as a threshold for determination, and the threshold for determination of clutch operation can be arbitrarily determined. Further, the clutch operation amount Cl serving as a threshold value may be changed according to the vehicle speed or the accelerator operation amount Ac.

Next, when it is determined that the clutch pedal is not operated (in the case of “No” in Step S105), the driving operation detection unit 3 causes the throttle control unit 2 to simultaneously operate the brake pedal and the accelerator pedal. Is transmitted (step S106). The throttle control unit 2 that has acquired the second operation detection information uses the first throttle characteristic indicated by reference numeral 5 in the throttle characteristic map 4 to determine the maximum throttle opening degree Th _MAX corresponding to the brake operation amount Br. (Step S107).
Then, the throttle control unit 2 calculates the throttle opening degree Th based on the accelerator operation amount Ac within the range of the maximum throttle opening degree Th _MAX (step S108), and the throttle valve corresponding to the throttle opening degree Th The control signal Sv is output to the throttle valve (step S104).

If it is determined that the clutch pedal has been operated (in the case of “Yes” in step S105), the driving operation detection unit 3 causes the throttle control unit 2 to simultaneously operate the accelerator pedal, the brake pedal, and the clutch pedal. Is transmitted (step S109). The throttle control unit 2 that has acquired the third operation detection information uses the second throttle characteristic indicated by reference numeral 6 in the throttle characteristic map 4 to determine the maximum throttle opening degree Th _MAX corresponding to the brake operation amount Br. (Step S110).
Then, the throttle control unit 2 calculates the throttle opening degree Th based on the accelerator operation amount Ac within the range of the maximum throttle opening degree Th _MAX (step S108), and the throttle valve corresponding to the throttle opening degree Th The control signal Sv is output to the throttle valve (step S104).

As a result, the second throttle characteristic of the throttle characteristic map 4 has a larger maximum throttle opening degree Th _MAX with respect to the same brake operation amount Br than the first throttle characteristic. Can be operated.

  Note that the operation of the engine output control device 1 of the present embodiment shown in FIG. 3 is continuously executed as a engine output control program every predetermined time (for example, several milliseconds).

As described above, according to the present embodiment described above, when the operator operates the brake pedal and the accelerator pedal at the same time, when the clutch pedal is operated, control is performed to increase the maximum throttle opening degree Th _MAX and the clutch pedal is operated. If not, control is performed to limit the maximum throttle opening Th _MAX . Thus, for example, when the operator performs a heel and toe operation, the engine can be operated up to a desired engine speed, and in other cases, the braking force is limited by limiting the engine speed. Can be suppressed, and wasteful fuel consumption can be suppressed. Also, in the throttle characteristic map 4 shown in FIG. 2, when the second throttle characteristic indicated by reference numeral 6 and the straight line drawn horizontally from 'T3' overlap, the brake, accelerator and clutch are operated simultaneously. In addition, since the throttle opening is always set within a range equal to or smaller than the maximum value “T3” of the throttle opening regardless of the brake operation amount, it is agreed that the control for suppressing the throttle opening is not performed.

(Second Embodiment)
Here, considering the double clutch operation, in the above-described procedure (b3), once the manual transmission is in the neutral position and the clutch is once engaged, the clutch operation amount Cl becomes “0”. Then, the accelerator pedal and the brake pedal will be operated. When the manual transmission is in the neutral position, the clutch is temporarily engaged and the accelerator pedal is operated to raise the engine to the desired engine speed, and the speed of the main shaft inside the transmission is synchronized with the engine speed. The load on the synchro mechanism can be reduced in conjunction with the rotation of the gear.

For this reason, in the vehicle to which the engine output control method of the first embodiment described above is applied, when the double clutch operation is performed, it is determined that the accelerator pedal and the brake pedal are operated simultaneously, and the driver The accelerator operation may cause a problem that the engine speed cannot be increased to a desired engine speed.
Therefore, in the second embodiment of the present invention, this problem is solved by using information on the shift position of the automatic transmission instead of information on the clutch operation amount Cl.

  In this embodiment, a sensor for detecting the operation amount of each pedal is installed in an accelerator pedal and a brake pedal of a vehicle including a manual transmission (not shown), and is installed in the accelerator pedal and the brake pedal. Hereinafter, the operation amounts detected by the sensors are referred to as an accelerator operation amount Ac and a brake operation amount Br, respectively. Further, the manual transmission is provided with a shift position sensor that detects at least the neutral position. In this embodiment, engine output control is performed by adjusting an injector control signal In that is a control signal for an injector that injects fuel into the engine.

Hereinafter, the second embodiment of the present invention will be described in detail.
Here, FIG. 4 is an example of a functional block diagram of the engine output control apparatus according to the present embodiment. The configuration and function of the engine output control device 11 will be described with reference to FIG. The engine output control device 11 of this embodiment is mainly composed of a fuel injection control unit 12, a driving operation detection unit 13, and a fuel injection characteristic map 14. Next, each component of the engine output control device 11 will be described.

The fuel injection control unit 12 calculates a fuel injection amount Fu from a signal such as an intake air amount, an engine speed, and a water temperature sensor so as to obtain an optimum air-fuel ratio for the engine by a predetermined algorithm (see FIG. 4). As a representative, only the engine speed and the intake air amount are displayed), and a fuel injection control function for outputting an injector control signal In to an injector that injects fuel into the engine. Further, when the fuel injection control unit 12 acquires a predetermined signal from the driving operation detection unit 13, the fuel injection control unit 12 refers to the fuel injection characteristic map 14, and the range of the maximum fuel injection amount Fu _MAX according to the brake operation amount Br. The control which outputs the injector control signal In corresponding to the fuel injection quantity Fu calculated in this to an injector is performed.

  When the accelerator operation amount Ac and the brake operation amount Br are detected at the same time, the driving operation detection unit 13 determines whether or not the shift position of the manual transmission is a neutral position, and displays information indicating the result as a fuel injection control unit. 12 is output.

The fuel injection characteristic map 14 is table data in which a correspondence relationship between the brake operation amount Br and the maximum fuel injection amount Fu _MAX is recorded. Here, FIG. 5 shows an example of the fuel injection characteristic map 14. As shown in FIG. 5, the fuel injection characteristic map 14 records a first fuel injection characteristic indicated by reference numeral 15 and a second fuel injection characteristic indicated by reference numeral 16. Here, the first fuel injection characteristic has a characteristic that the maximum fuel injection amount Fu _MAX is suppressed with respect to the same brake operation amount Br as compared to the second fuel injection characteristic. For example, as shown in FIG. 5, when the brake operation amount Br is “B1”, the maximum fuel injection amount Fu _MAX in the first fuel injection characteristic “P1” is the maximum fuel in the second fuel injection characteristic. It can be seen that the injection amount Fu _MAX is lower than “P2”. 'P3' is the maximum value of the fuel injection amount, and the second fuel injection characteristic is between the first fuel injection characteristic and a straight line drawn horizontally from 'P3' shown by the broken line in FIG. Is set.

  The engine output control device 11 of the present embodiment is embodied by developing and executing an engine output control program stored in the ROM on a RAM in a computer having a CPU, RAM, ROM, input / output interface, and the like. The fuel injection characteristic map 14 is stored in the ROM.

  Next, the operation of the engine output control device 11 will be described with reference to the flowchart shown in FIG.

  First, as in the first embodiment, in order to determine whether or not the accelerator pedal and the brake pedal are operated at the same time, has the driving operation detection unit 13 detected the accelerator operation amount Ac and the brake operation amount Br at the same time? It is determined whether or not (step S201).

  Here, when it is determined that the accelerator pedal and the brake pedal are not operated simultaneously (in the case of “No” in step S201), the driving operation detection unit 13 detects the accelerator operation amount Ac and the brake operation amount Br simultaneously. The fourth operation detection information indicating that there is no transmission is transmitted to the fuel injection control unit 12 (step S202). The fuel injection control unit 12 that has acquired the fourth operation detection information calculates the fuel injection amount Fu based on signals such as the intake air amount, the engine speed, and the water temperature sensor by a predetermined algorithm (step S203). An injector control signal In corresponding to the fuel injection amount Fu is output to the injector (step S204).

  Next, when it is determined that the accelerator pedal and the brake pedal are operated simultaneously (in the case of “Yes” in Step S201), the driving operation detection unit 13 determines whether or not the shift position is a neutral position (Step S201). S205). Here, whether or not the shift position is the neutral position is determined based on information from a shift position sensor installed in the manual transmission.

Next, when it is determined that the position is not the neutral position (“No” in step S205), the driving operation detection unit 13 indicates to the fuel injection control unit 12 that the brake pedal and the accelerator pedal are operated simultaneously. The fifth operation detection information is transmitted (step S206). The fuel injection control unit 12 that has acquired the fifth operation detection information uses the first fuel injection characteristic indicated by reference numeral 15 in the fuel injection characteristic map 14, and uses the first fuel injection characteristic Fu _MAX corresponding to the brake operation quantity Br. Is determined (step S207).
Then, the fuel injection control unit 12 calculates a fuel injection amount Fu corresponding to the engine speed or the like within the range of the maximum fuel injection amount Fu _MAX (step S208), and an injector corresponding to the fuel injection amount Fu. The control signal In is output to the injector (step S204).

When it is determined that the manual transmission is in the neutral position (in the case of “Yes” in step S205), the driving operation detection unit 13 causes the fuel injection control unit 12 to operate the accelerator pedal and the brake pedal simultaneously, Sixth operation detection information indicating the neutral position is transmitted (step S209). The fuel injection control unit 12 that has acquired the sixth operation detection information uses the second fuel injection characteristic indicated by reference numeral 16 in the fuel injection characteristic map 14, and uses the second fuel injection characteristic Fu _MAX corresponding to the brake operation quantity Br. Is determined (step S210).
Then, the fuel injection control unit 12 calculates the fuel injection amount Fu according to the engine speed and the like within the range of the maximum fuel injection amount Fu _MAX (step S208), and the injector according to the fuel injection amount Fu. The control signal In is output to the injector (step S204).

  Note that the operation of the engine output control apparatus 11 of the present embodiment shown in FIG. 6 is continuously executed as an engine output control program every predetermined time.

As described above, according to the present embodiment described above, when the operator operates the brake pedal and the accelerator pedal at the same time, if the manual transmission is in the neutral position, control is performed to increase the maximum fuel injection amount Fu _MAX. If not, control is performed to limit the maximum fuel injection amount Fu _MAX . Thus, for example, when the driver performs a double clutch operation, the engine can be operated up to a desired engine speed, and in other cases, the fuel supply to the engine is limited. The influence on the braking force can be suppressed, and wasteful fuel consumption can be suppressed. In the fuel injection characteristic map 14 shown in FIG. 5, when the second fuel injection characteristic indicated by reference numeral 16 and the straight line drawn horizontally from “P3” overlap, the brake and the accelerator are operated simultaneously, When the shift position is neutral, the fuel injection amount is always set within the range of the maximum value 'P3' of the fuel injection amount regardless of the brake operation amount, so that control for suppressing the fuel injection amount is not performed. I agree.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made.
For example, in the first embodiment, the engine output control is performed based on the clutch operation amount Cl, and in the second embodiment, based on the shift position, the first embodiment and the second embodiment And engine output control may be performed based on either the clutch operation amount Cl or the shift position.

  Further, in the first embodiment, the throttle opening degree Th is controlled, and in the second embodiment, the engine output control is disclosed by controlling the fuel injection amount Fu. However, this is only an example, For example, the engine output can be controlled by using the ignition timing control of the engine so that the engine is not ignited under a predetermined condition. It can be implemented.

Further, for example, in the first embodiment, when the accelerator pedal and the brake pedal are simultaneously operated and the clutch pedal is operated, the third operation detection information is transmitted from the driving operation detection unit 3 to the throttle control unit 2. As a result, the maximum throttle opening degree Th _MAX is changed to the second throttle characteristic. However, if the accelerator pedal and the brake pedal are operated at the same time and the clutch pedal is operated or the shift position is in the neutral position, As in the case where the operation and the accelerator operation are not detected at the same time, the first operation detection information can be transmitted to the throttle control unit 2. In this case, the algorithm is simplified and the throttle characteristic map is also transmitted. 4 need not be stored.

  As described above, the present invention is not limited to the matters disclosed in the above-described embodiments, but is defined by the technical idea described in the claims.
