In the following description, suffixes such as "module", "part" or "unit" for representing elements are used only for facilitating the description of the present application, and have no specific meaning per se. Thus, "module," "component," or "unit" may be used in combination.

It should be noted that, the electric brake booster systems mentioned in the present application refer to NBS (Nissan Brake System) electric brake booster systems, which are generally implemented by cooperation of electronic control and various sensors, and are used for helping vehicles maintain safe driving speeds, reducing risks of drivers and passengers, and helping to improve driving safety. The manner in which the NBS electric brake assist system provides brake assistance to the vehicle may include:

First, the braking force is adjusted based on the vehicle speed and input signals from other sensors located in the electric brake booster system. Specifically, the braking force can be adjusted according to the difference between the current vehicle speed and the target vehicle speed, and when the difference between the current vehicle speed and the target vehicle speed is large, the NBS electronic brake booster system can increase the braking force to reduce the vehicle, so that the vehicle speed can reach the speed range of safe running in a short time.

Second, NBS electric brake assist systems are typically equipped with wheel speed sensors that can monitor the speed of the wheels, and by communicating the wheel speed sensors to the vehicle's electronic control unit, the NBS electric brake assist system can detect whether the wheels are rotating too fast and, when it is detected, take braking action to slow the vehicle.

In summary, the NBS electric brake booster system aims at improving the braking performance and driving safety of a vehicle, adapting to different driving conditions by electronically controlling and intelligently distributing braking forces, preventing wheel locking, providing better handling performance, helping a driver to maintain the stability of the vehicle in case of emergency, and the like. These functions help reduce the risk of accidents and improve driving comfort.

Referring to fig. 1, a vehicle control method according to an embodiment of the present application includes an electric brake booster system, where the electric brake booster system includes a displacement sensor; the vehicle control method may be executed by a vehicle control device provided by the embodiment of the present application, where the vehicle control device may be implemented in a software and/or hardware manner, for example, in an electronic device such as a vehicle-mounted terminal, a vehicle-mounted controller, etc., and the vehicle control method provided by the embodiment of the present application includes:

and step S1, acquiring state information of an accelerator pedal of the vehicle in response to detecting that a brake pedal switch and the displacement sensor of the vehicle are invalid.

Wherein, the displacement sensor is arranged in the electronic power-assisted braking system and can comprise at least one of the following components: brake pedal displacement sensor and brake booster displacement sensor. The brake pedal displacement sensor is arranged on the brake pedal and used for monitoring the operation of the brake pedal of a driver and determining the braking requirement of the driver according to the position and the movement state of the pedal. Brake booster displacement sensors are typically mounted on the brake booster for monitoring the position and movement of the booster input push rod to assist the system in providing proper brake assistance based on the needs of the driver.

Alternatively, the electronic device may detect the brake pedal switch and the displacement sensor of the vehicle in real time, periodically or sporadically to determine whether both the brake pedal switch and the displacement sensor of the vehicle are disabled. In one embodiment, the vehicle brake pedal switch and the displacement sensor are both disabled, comprising: the displacement sensor is in an open fault condition and the brake pedal switch condition is inactive.

It will be appreciated that when the displacement sensor has an open circuit fault due to a fault in itself, a wire connection or power supply, etc., i.e., the displacement sensor is in an open circuit fault condition, no effective electrical signal will be provided. While the displacement sensor is in an open circuit fault condition, the vehicle may not accurately monitor the position or motion of the brake components, which may affect the performance of the electric brake assist system and the safety of the vehicle. Similarly, an invalid brake pedal switch state may mean that the brake pedal switch is not functioning properly or providing a proper signal, which may be caused by a malfunction of the switch itself, a connection problem or a power supply problem, while an invalid brake pedal switch state may result in the electric brake assist system not accurately sensing the driver's brake operation, which may also negatively affect the performance and safety of the electric brake assist system.

And step S2, judging whether the vehicle has braking requirements or not according to the state information of the accelerator pedal.

Optionally, the determining whether the vehicle has a braking requirement according to the state information of the accelerator pedal may include: detecting whether the accelerator pedal switch signal is valid or not and whether the accelerator pedal switch signal is set or not when the accelerator pedal switch signal is valid; and if the accelerator pedal switch signal is valid and not set, determining that the vehicle has a braking requirement.

It will be appreciated that if the accelerator pedal switch signal is active, it may be determined that the accelerator pedal switch is activated, and when the accelerator pedal switch signal is active, the electric brake assist system will check whether a flag bit indicating the accelerator pedal switch signal has been set to indicate the validity of this signal. If the accelerator pedal switch signal is valid, but the flag bit is not set, i.e., not set, the electric brake booster system recognizes that the vehicle may be traveling at a relatively high speed, and the vehicle has a braking demand, so that the electric brake booster system is required to perform a speed-limiting braking operation when both the displacement sensor of the electric brake booster system and the brake pedal switch signal are disabled.

Optionally, the determining whether the vehicle has a braking requirement according to the state information of the accelerator pedal further includes: if the accelerator pedal switch signal is not valid, it is determined that the vehicle has no braking demand.

It will be appreciated that when the accelerator pedal switch signal is inactive, it means that the electronic brake assist system is not reading the accelerator pedal switch state information, and therefore the current running state of the vehicle cannot be determined, and in the case where the current running state of the vehicle is not clear, no brake assist is provided by the electronic brake assist system, and therefore in the case where the accelerator pedal switch state information is inactive, the vehicle is considered to have no brake demand.

In some embodiments, the above method further comprises: an automatic high beam control (High Beam Control, HBC) function of the vehicle is activated to turn on the high beam for prompting. It will be appreciated that when either the accelerator pedal switch signal is active but not set, or the accelerator pedal switch signal is inactive, it is indicative that the driver's operation of the accelerator pedal is not properly interpreted or detected by the electric brake assist system, which generally means that the vehicle's electric brake assist system or monitoring system does not receive a normal signal to indicate the status or position of the accelerator pedal. In this case, the electric brake booster system of the vehicle may enter a specific failure mode or safety mode to ensure driving safety. Activating the automatic high beam control function may be a strategy for a failure mode or a safety mode, where the driver may lose control of the vehicle or may not be able to accurately control the speed of the vehicle when the accelerator pedal signal is active but not set or inactive. Therefore, activating the automatic high beam control function to turn on the high beam can secure the driving safety of the vehicle from the following aspects: (1) Better road illumination is provided, so that a driver can see clearly obstacles on the road, and potential hazards are reduced; (2) Prompting the driver that the current driving condition is possibly abnormal, and prompting the driver to take appropriate action to solve the current existing problem; (3) And sending a prompt to other vehicles or pedestrians to pay attention to avoiding the current vehicle.

Optionally, the determining whether the vehicle has a braking requirement according to the state information of the accelerator pedal further includes: if the accelerator pedal switch signal is active and set, it is determined that the vehicle has no braking demand.

It will be appreciated that the accelerator pedal switch is active, indicating that the status information of the accelerator pedal switch is correctly read by the electric brake assist system, and that the accelerator pedal switch is depressed, meaning that the user has the intention to increase the speed of the vehicle. When the electronic brake assistance system detects that the accelerator pedal signal is valid, the electronic brake assistance system checks whether a flag bit representing the accelerator pedal switch signal has been set to indicate the validity of this signal. If the accelerator pedal switch signal is active and the flag bit has been set, i.e., set, indicating that the electric brake assist system has noticed the user's intent, no immediate braking operation is required.

And step S3, providing braking assistance for the vehicle through the electronic braking assistance system when the vehicle is determined to have braking requirements.

Specifically, when it is determined that the vehicle has a braking demand, braking assistance is provided to the vehicle by the electric brake assistance system to assist in reducing the vehicle running speed.

In summary, in the method provided in this embodiment, when both the displacement sensor of the electric brake booster system of the vehicle and the brake pedal switch signal fail, the state of the accelerator pedal of the vehicle is detected to determine whether the vehicle has a brake demand, and if so, the electric brake booster system is used to perform brake boosting, so that when it is detected that both the displacement sensor of the electric brake booster system of the vehicle and the brake pedal fail and the vehicle has a brake demand, the brake boosting can be timely provided to improve the braking force of the whole vehicle, thereby improving the safety of the vehicle and reducing the operation level requirements on the driver.

Based on the same inventive concept as the previous embodiment, the previous embodiment will be described in detail by a specific embodiment, and referring to fig. 2, a schematic diagram of a vehicle control process according to an embodiment of the present invention is provided.

As shown in fig. 2, the NBS electric brake booster system includes a signal processing unit and a braking force control unit, and the signal processing unit is used to identify a brake pedal switch signal, a displacement sensor signal of the electric brake booster system and an accelerator pedal switch signal, but the identification process has a sequence. When the signal processing unit recognizes that the brake pedal switch signal is invalid and the displacement sensor of the electric brake booster system is in an open circuit fault, the signal processing unit can acquire and recognize the accelerator pedal switch signal.

Specifically, after the signal processing unit acquires the accelerator pedal switch signal, the signal processing unit identifies the accelerator pedal switch signal and sends the identification result to the braking force control unit, and the braking force control unit determines whether to provide braking assistance for the vehicle according to the identification result of the accelerator pedal switch signal. Wherein, aiming at the recognition result of the accelerator pedal switch signal, the corresponding processing mode of the braking force control unit is as follows:

1) The accelerator pedal switch signal is active and set, this state indicates that the state information of the accelerator pedal switch is correctly read by the NBS electric brake assist system and that the accelerator pedal switch is depressed, meaning that the user has an intention to increase the vehicle speed, and the flag bit has been set, indicating that the NBS electric brake assist system has noticed the user's intention and that no immediate braking operation is required, so this state does not require the NBS electric brake assist system to provide brake assist.

2) The accelerator pedal switch signal is active and not on, which indicates that the accelerator pedal switch is activated, but the NBS electric brake booster system cannot detect the actual running state of the vehicle, and the NBS electric brake booster system recognizes that the vehicle may be running at a large speed, and therefore, in this state, the NBS electric brake booster system is required to perform a speed-limiting brake operation. However, the NBS electronic brake booster system cannot detect the actual running state of the vehicle, and the automatic high beam control function can be activated while providing brake booster so as to prompt dangerous driving for a user.

3) The accelerator pedal switch signal is not valid, and this state indicates that the NBS electronic brake system cannot correctly recognize the accelerator pedal switch signal, so that the current running state of the vehicle cannot be determined, and in the case where the current running state of the vehicle is not clear, no brake assistance is provided by the NBS electronic brake assistance system, so that when the accelerator pedal switch state information is invalid, the vehicle is considered to have no brake demand. Similarly, the NBS electronic brake booster system cannot detect the current running state of the vehicle, so that the automatic high beam control function can be activated to prompt a user.

In summary, in the vehicle control method provided in the above embodiment, the braking intention of the driver is determined based on the NBS displacement sensor signal, the brake pedal switch state signal and the accelerator pedal state signal identified by the NBS electric brake booster system, and after the NBS displacement sensor and the brake pedal switch are deactivated, whether the driver has a braking requirement is determined through the accelerator pedal state, and an emergency braking force is provided when the driver has a braking requirement, so that the safety performance of the whole vehicle is improved.
