In the prior art, when the accident is serious and the emergency call eCall of the accident vehicle cannot be used, the accident vehicle cannot call for help, which leads to the problem that the rescue of the wounded in the accident vehicle is not timely.

Based on this, the embodiment of the present application provides a vehicle call for help system and method, by controlling the repeater to send a call for help signal when the emergency call of the accident vehicle cannot be used, so that other vehicles except the accident vehicle can receive the call for help signal It will be reported to the rescue center, thereby solving the technical problem that the accident vehicle cannot ask for help when the emergency call cannot be used, and achieves the technical effect of improving the probability of the accident vehicle being rescued. details as follows:

Please refer to FIG. 1 . FIG. 1 is an interaction diagram of a vehicle emergency call system provided by an embodiment of the present application. As shown in FIG. 1 , the vehicle emergency call system provided by the embodiment of the present application includes an accident vehicle and a target vehicle other than the accident vehicle.

S101: Determine whether the emergency call eCall is activated.

Specifically, after the accident, the vehicle in the accident displays the button corresponding to the emergency call eCall through the on-board display and records the display duration of the button to determine whether the display duration is greater than the preset display duration. If the display duration is greater than the preset display duration, control the eCall Start, that is, eCall sends a distress signal to the emergency center; if the display duration is less than or equal to the preset display duration, the emergency call button will be continuously displayed on the vehicle display screen and the display duration of the emergency call button will be recorded.

That is to say, when the display duration is longer than the preset display duration, the user in the accident vehicle cannot click the emergency call button within the preset display duration. The emergency call eCall is activated, and the distress signal is sent to the ambulance center.

After the accident, the emergency call button and the self-call button are displayed on the vehicle display screen; in response to the click instruction of the emergency call button, the eCall is controlled to start; or, in response to the click instruction of the self-call button, the eCall is not controlled to start And control the vehicle-mounted display screen not to display the emergency call button and the self-call button. That is to say, after the accident is sent, if it responds to the click instruction of the emergency call button, it is considered that the user in the accident vehicle can click the emergency call button to call for help; if it responds to the click instruction of the self-call button, it is considered that the accident vehicle Users within the system can call for help by themselves.

Determining whether the emergency call eCall is activated includes: determining whether the eCall sends a distress signal to the emergency call center; if the eCall does not send a distress signal to the emergency call center, then determining that the emergency call eCall is not activated.

S102: Control the repeater to send a distress signal.

If eCall is not activated, control the repeater to send a distress signal. Among them, the distress signal is used to describe the accident situation, and the accident situation includes the location of the accident and the information of the vehicle owner. The distress signal includes the accident vehicle identification, the location of the accident, and the owner information.

The range of the distress signal sent by the repeater is within a circular area with a radius of a preset kilometer centered on the accident site, wherein the value range of the preset kilometer is 2 to 6 kilometers. A repeater is a device that connects network lines and is often used for bidirectional forwarding of physical signals between two network nodes. Controlling the repeater to send a distress signal can be understood as controlling the repeater to send a distress signal at preset intervals.

Specifically, the accident vehicle is used to determine whether the emergency call eCall is activated. If the eCall is not activated, the repeater is controlled to send a distress signal, and the distress signal is used to describe the accident situation; if the eCall is activated, there is no need to control the repeater to send a distress signal.

The accident vehicle is also used to determine whether the Vehicular ad-hoc network (VANET) is available if the eCall is not activated, and to send a distress signal to the rescue center through the VANET if the VANET is available.

S103: Receive a distress signal through a radio receiver.

The target vehicle receives the distress signal via a radio receiver. That is to say, the target vehicle is equipped with a radio receiver, and the target vehicle is located within the range where the repeater of the accident vehicle sends the distress signal, so that the radio receiver of the target vehicle can receive the distress signal.

S104: Send a processing signal corresponding to the distress signal.

The target vehicle is also used to control the repeater to send the processing signal corresponding to the distress signal. The processing signal is used to describe that the user in the target vehicle has reported the accident to the rescue center.

The processed signal includes the identification of the accident vehicle in the distress signal corresponding to the processed signal.

S105: Determine whether the radio receiver receives the processing signal corresponding to the distress signal, if the radio receiver receives the processing signal corresponding to the distress signal, complete the distress call and control the repeater to stop sending the distress signal.

The accident vehicle is also used to determine whether the radio receiver has received the processing signal corresponding to the distress signal. If it is determined that the radio receiver has received the processing signal corresponding to the distress signal, the call for help is completed and the repeater is controlled to stop sending the distress signal. The accident vehicle is also used to continue to control the repeater to send the distress signal if the radio receiver does not receive the corresponding processing signal of the distress signal.

Specifically, before the accident vehicle is used to determine whether the radio receiver has received the corresponding processing signal of the distress signal, the accident vehicle is also used to determine whether the radio receiver has received the wireless signal; if the radio receiver does not receive the wireless signal, it is considered The radio receiver does not receive the processing signal corresponding to the distress signal, and continues to control the repeater to send the distress signal; if the radio receiver receives the wireless signal, it is determined that the radio receiver receives the accident vehicle identification and the distress signal in the wireless signal. If the radio receiver receives the same accident vehicle identification in the wireless signal and the accident vehicle identification in the distress signal, it is determined that the radio receiver receives the processing signal corresponding to the distress signal, and the repeater is controlled to stop sending Mayday.

Specifically, after the target vehicle receives the distress signal, it is also used to display the processing button and the ignore button corresponding to the distress signal on the vehicle display screen, and in response to the click instruction on the processing button, control the repeater to send the processing signal, or, respond Based on the instruction of clicking the ignore button, the repeater is controlled to send a distress signal.

While the target vehicle displays the processing button and ignore button corresponding to the distress signal on the vehicle display screen, it can also broadcast the accident situation such as the accident vehicle logo, accident location and owner information in the distress signal through the voice broadcast device to remind the target users in the vehicle.

That is to say, after the processing button and the ignore button corresponding to the distress signal are displayed on the vehicle-mounted display screen in the target vehicle, the target vehicle receives the user's click instruction on the processing button in the target vehicle, and displays the location of the accident, the owner's location, and the location of the accident on the vehicle-mounted display screen. The accident situation in the distress signal such as information, so that the user in the target vehicle can report the accident information to the rescue center. Or, if the target vehicle receives an instruction to click the ignore button from the user in the target vehicle, the repeater is controlled to send a distress signal. That is to say, the user in the target vehicle cannot report the accident situation to the rescue center in time, so the repeater will also be controlled to continuously send a distress signal to the surroundings during the driving process of the target vehicle, so that the repeater located in the target vehicle can send a distress call. More vehicles within the range of the signal will report the accident information to the rescue center after receiving the distress signal.

After the target vehicle controls the repeater to send the distress signal, the target vehicle is also used to determine whether the radio receiver receives the wireless signal; if it is determined that the radio receiver receives the wireless signal, then determine whether the radio receiver receives the wireless signal is the distress The processing signal corresponding to the signal; if it is determined that the radio receiver has received the processing signal corresponding to the distress signal, then controlling the repeater to send the processing signal corresponding to the distress signal. Control the repeater to send the processing signal so that the wireless repeater of the accident vehicle receives the processing signal and stop the control repeater from sending the distress signal; if the accident vehicle identification in the wireless signal is compared with the accident vehicle identification in the distress signal If the results are inconsistent, it is determined that the radio receiver has not received the processing signal corresponding to the distress signal, and continues to control the repeater to send the distress signal.

If the target vehicle receives the processing signal corresponding to the distress signal, that is to say, users in other vehicles other than the target vehicle report the accident situation to the rescue center, then the above-mentioned other vehicles send the corresponding processing signal of the distress signal through the repeater signal, the target vehicle is located within the range of the repeater of the above-mentioned other vehicles to send processing signals, so that the target vehicle receives the processing signal corresponding to the distress signal, and the target vehicle sends the processing signal corresponding to the distress signal to the accident vehicle, so that the target vehicle and The accident vehicles all control their respective repeaters to stop sending distress signals.

After the target vehicle responds to the click instruction of the ignore button, the target vehicle is also used to record the receiving time of the distress call signal containing the accident vehicle identification; determine whether within the preset time range after the latest recorded receiving time The distress signal is received; if the distress signal is not received within a preset time range after the latest recorded receiving time, the repeater is controlled to stop sending the distress signal.

The preset time range may be to determine the time interval for receiving the distress signal according to the recorded receiving time of the distress signal including the identification of the vehicle in the accident.

The target vehicle determines whether the distress signal is received within the preset time range after the latest recorded receiving time. It can also be said that the target vehicle determines whether the distress signal can be continuously received; if the distress signal is continuously received, it is considered to have received the distress signal. The user in the vehicle of the distress signal clicked the ignore button. If the distress signal is not continuously received, the target vehicle considers that the accident vehicle has received the processed signal and no longer sends the distress signal. That is, if the distress signal is not continuously received, the target vehicle is not sending the distress signal.

Specifically, after the target vehicle receives the distress signal containing the accident vehicle label for the first time, if the target vehicle receives the distress signal again, the target vehicle may no longer display the processing button and ignore button corresponding to the distress signal through the display screen.

The vehicle emergency system also includes: a roadside unit.

The target vehicle is also used to determine if the radio receiver has not received the processing signal corresponding to the distress signal, then determine whether the sending duration of the distress signal is longer than the preset duration, and if the sending duration of the distress signal is longer than the preset duration, then determine the location of the accident. Whether there is a roadside unit (Road Side Unit, RSU) within the preset range of the accident location, if there is a roadside unit within the preset range corresponding to the accident location, the target vehicle will transmit the distress signal through its own on board unit (OBU) Send to the roadside unit and control the repeater to stop sending the distress signal.

The target vehicle can determine the duration of sending the distress signal in the following ways: start timing from the first time the target vehicle repeater sends the distress signal, and use the timing as the duration of sending the distress signal, or, the target vehicle receives the distress signal for the first time The signal starts timing, and the timing is used as the sending duration of the distress signal.

The roadside unit is used to report the accident situation to the rescue center; the roadside unit is also used to send the location of the accident to the electronic map corresponding to the roadside unit, so that the place where the accident was sent is displayed on the electronic map.

Specifically, the roadside unit can send the location of the accident to the electronic map server corresponding to the roadside unit, so that the accident location is marked on the electronic map, so that other users who use the electronic map can view the accident location and thereby bypass.
