[0038] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0039] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The main solutions of the embodiments of the present application are: monitoring the vehicle's braking action signal and / or traction fault signal; judging whether the vehicle has a braking fault and / or traction fault based on the braking action signal and / or traction fault signal; in the event that the vehicle has a braking fault and / or traction fault, disconnecting the power supply of the vehicle's power control unit to cut off the vehicle's power output; wherein the power control unit includes an engine control unit and / or a motor control unit.

[0041] In the related art, the vehicle's brake system and traction system component failures can be monitored in real time through monitoring circuits installed on the vehicle, and a reminder message can be sent to the driver to remind the driver to brake in time. However, the above method only reminds the driver that the vehicle has a fault. In an emergency, the driver may find it difficult to react in time and take effective countermeasures, so the safety of the driving process is difficult to ensure.

[0042] The present application provides a solution that can monitor the brake action signal and traction fault signal during the operation of the vehicle in real time, so as to promptly determine whether the vehicle has a brake fault and a traction fault; thereby, when a vehicle fault occurs, the power supply of the vehicle's power control unit can be controlled to be disconnected, and the vehicle's power output can be cut off in time, so that the vehicle can be stopped safely and the driving safety of the driver can be guaranteed.

[0043] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, etc., or an electronic device capable of realizing the above functions, etc. The following takes a vehicle controller as an example to illustrate this embodiment and the following embodiments.

[0044] Based on this, the embodiment of the present application provides a vehicle control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle control method of the present application.

[0045] In this embodiment, the vehicle control method may include steps S100 to S300:

[0046] Step S100, monitoring the braking action signal and / or traction fault signal of the vehicle.

[0047] Step S200: Based on the brake action signal and / or the traction fault signal, determine whether the vehicle has a brake fault and / or a traction fault.

[0048] Step S300: When the vehicle has a braking failure and / or a traction failure, disconnect the power supply of the power control unit of the vehicle to cut off the power output of the vehicle.

[0049] The power control unit includes an engine control unit and / or a motor control unit.

[0050] Specifically, vehicles are generally equipped with two major systems: a braking system and a traction system. Among them, the braking system is a key system to ensure that the vehicle can decelerate to a stop normally, while the traction system is the vehicle's power transmission system, which can transfer the power generated by the engine or motor to the wheels to drive the vehicle forward. Therefore, whether the braking system and the traction system have faults is crucial to the normal operation of the vehicle. The braking system is usually equipped with equipment such as brake pressure sensors, brake pedal sensors, and wheel speed sensors, which can provide real-time feedback on the vehicle's braking action status; or the relevant monitoring circuits configured in the braking system can be used to monitor the action status of each component in the braking system to determine the vehicle's braking action status. The traction system is also equipped with relevant monitoring circuits and sensors, which can monitor whether the traction system has abnormalities in real time and output traction fault signals; for example, the wheel speed sensor can be used to determine whether the wheel is slipping, and then determine whether there is insufficient traction or loss of control.

[0051] The vehicle's braking system and traction system are both connected to the vehicle controller of the vehicle. The vehicle controller can monitor the received braking action signal output by the braking system and / or the traction fault signal output by the traction system in real time, and judge whether the current vehicle has a braking system fault and a traction fault based on the braking action signal and the traction fault signal; for example, the traction fault signal can be an engine fault signal or a motor fault signal, and the engine fault signal and the motor fault signal are in the form of a pulse signal (including two pulses, fault and normal); the braking action signal can also be in the form of a pulse signal (including a connection signal and a disconnection signal); the vehicle controller can monitor the changes in the braking action signal and the engine fault signal / motor fault signal in real time, and compare them with the first signal threshold corresponding to the disconnection detection program set in the memory and the second signal threshold corresponding to the fault detection program to determine whether the vehicle currently has a fault; when the braking action signal exceeds the first signal threshold, it can be determined that the vehicle has a braking fault; when the engine fault signal or the motor fault signal exceeds the second signal threshold, it can be determined that the vehicle has a traction fault.

[0052] When the vehicle controller determines that the vehicle has a brake fault and / or a traction fault, it can generate a fault alarm message to remind the driver that the vehicle's traction system has a fault and / or a brake system has a fault. In order to allow the driver to receive the fault alarm message more intuitively, the fault alarm message may include at least one of a sound alarm message, a light alarm message, and a text alarm message. For example, when the vehicle controller determines that the vehicle has a brake fault or a traction fault, it can output the fault alarm message to the vehicle's instrument panel. The instrument panel, as an alarm medium, can start the preset strong red alarm interface flashing, the buzzer beeps continuously, and the fault text display after receiving the above fault alarm message, and remind the driver in the form of sound and light text that the vehicle's brake system and / or traction system has a fault. When the vehicle is in a parking state or a restarting state, and there is no traction fault signal and brake action signal in these two states, the vehicle's fault alarm message can be cancelled until the next time the vehicle fails.

[0053] In order to avoid dangerous driving when the vehicle has a fault and to ensure the driving safety of the driver, when the vehicle has a brake fault and / or traction fault, the power supply of the vehicle's power control unit can be disconnected to cut off the vehicle's power output. The vehicle's power control unit is used to control the vehicle's power output, which varies with the type of vehicle. For example, the power control unit of a fuel vehicle is an engine control unit, the power control unit of an electric vehicle is a motor control unit, and the power control unit corresponding to a hybrid vehicle includes an engine control unit and a motor control unit. In a feasible implementation, refer to Figure 2 , Figure 2 is a detailed flow chart of step S300, such as Figure 2 As shown, step S300 may specifically include steps S310 to S320, which are used to confirm the power cut-off operation:

[0054] Step S310: when the vehicle has a braking failure and / or a traction failure, output a power cut-off prompt message.

[0055] The power cut prompt information is used to remind the driver to perform the power cut confirmation operation.

[0056] Step S320, in response to the driver's power cut confirmation operation, disconnecting the power supply of the power control unit of the vehicle.

[0057] Specifically, when confirming that the vehicle has a brake fault and / or a traction fault, the vehicle controller can generate and output a power cut-off prompt message; the power cut-off prompt message can be output to the driver through the vehicle information system (such as the instrument panel, the driver display screen or the voice prompt, etc.), indicating that the driver currently has a potential safety hazard in the vehicle and needs to perform a power cut-off operation; the driver can perform a power cut-off confirmation operation according to the power cut-off prompt message, so that the vehicle controller can respond to the driver's power cut-off confirmation operation, disconnect the power supply of the vehicle's power control unit, and cut off the vehicle's power output, so that the vehicle can stop safely. It can be understood that the above design is a mechanism to ensure safety by enhancing user interaction, which can ensure that the power cut-off operation is clearly confirmed by the driver, avoiding the wrong cut-off operation caused by system misjudgment or fault prompts. Through this process, the driver is reminded and has the opportunity to confirm the power cut-off operation, and can also avoid the danger that may be caused by continuing to drive when a fault occurs. Once the driver confirms, the vehicle controller will disconnect the power supply of the power control unit to ensure that the power output stops to protect the safety of the driver.

[0058] The above-mentioned power cut confirmation operation can be a voice reply of the driver "turn on power cut", or the driver can directly click the confirmation button on the touch screen of the vehicle. Or as a feasible implementation, the power cut confirmation operation can also be a long press of the steering wheel confirmation key; under this implementation, step S320 can specifically include: when it is detected that the steering wheel confirmation key of the vehicle is pressed for a preset time, disconnecting the power supply of the power control unit. By long pressing the steering wheel confirmation key to confirm the power cut, the driver does not need to divert his sight or move his hand to other positions, thereby reducing the time distracted by looking for the confirmation button. In the event of an emergency such as a brake failure or traction failure in the vehicle, the confirmation button set on the steering wheel allows the driver to respond quickly to cut off the power, thereby reducing potential safety risks. For example, in one example, after the vehicle dashboard displays a fault text to remind the driver that the vehicle has a traction fault or a brake fault, the fault text display can be switched to a pop-up screen display of "Traction system / brake system fault, please long press the steering wheel confirmation key to cut off the vehicle power!"; in actual applications, after the vehicle controller determines that the vehicle has a fault, it can output a fault determination signal to the steering wheel confirmation key. The steering wheel confirmation key is used as an operation button. After receiving the fault determination signal (a prerequisite for long-pressing the power-cutting operation), the long-pressing operation signal can be calibrated as a power-cutting signal. At this time, the driver long-presses the steering wheel confirmation key to execute the power-cutting operation. The dedicated control circuit of the vehicle controller can determine that the power-cutting function needs to be executed after receiving the power-cutting signal input by the steering wheel. At this time, the dedicated control circuit of the vehicle controller will cut off the power supply of the engine control unit or the motor control unit, terminate the vehicle power output, and stop the vehicle safely.

[0059] It can be understood that the vehicle control method provided by the present application can monitor the braking action signal and traction fault signal during the operation of the vehicle in real time, so as to promptly determine whether the vehicle has a braking fault and a traction fault; thereby, when a vehicle fault occurs, the power supply of the vehicle's power control unit can be controlled to be disconnected, and the vehicle's power output can be cut off in time, so that the vehicle can be stopped safely and the driving safety of the driver can be ensured.

[0060] This application also provides a vehicle control device, please refer to Figure 3 , which can be configured in a vehicle controller, the vehicle control device includes:

[0061] A signal monitoring module 10, used to monitor a braking action signal and / or a traction failure signal of the vehicle;

[0062] A fault judgment module 20 judges whether the vehicle has a braking fault and / or a traction fault based on the braking action signal and / or the traction fault signal;

[0063] The power cut-off module 30 is used to disconnect the power supply of the power control unit of the vehicle to cut off the power output of the vehicle when the vehicle has a braking failure and / or a traction failure; wherein the power control unit includes an engine control unit and / or a motor control unit.

[0064] The vehicle control device provided by the present application adopts the vehicle control method in the above embodiment, which can solve the technical problem that the driver is unable to respond in time when the vehicle fails, causing the driving safety to be difficult to ensure. Compared with the relevant technology, the beneficial effects of the vehicle control device provided by the present application are the same as the beneficial effects of the vehicle control method provided by the above embodiment, and the other technical features in the above vehicle control device are the same as the features disclosed in the above embodiment method, which will not be repeated here.

The braking system is connected to the vehicle controller of the vehicle and can output a braking action signal to the vehicle controller. The braking system is generally equipped with relevant monitoring circuits to monitor the action status of each component in the braking system. For example, it can monitor the braking action signal (connection signal, disconnection signal) of the vehicle's brake parts and output the braking action signal to the vehicle controller.
