The invention discloses a brake signal fault detection system and method for a vehicle. The system comprises a vehicle control unit, a chassis controller and a brake pedal, wherein the vehicle controlunit and the chassis controller are connected through a CAN bus; the brake pedal comprises a first switch electrically connected to the chassis controller and a second switch electrically connected to the vehicle control unit, and the first switch and the second switch can independently generate a first brake signal and a second brake signal which represent the action of the brake pedal; the chassis controller can judge the state of the brake pedal and send the judgment result to the vehicle control unit; and the vehicle control unit can judge the state of the brake pedal, and send out a brake signal fault early warning when the judgment result of the vehicle control unit is different from the judgment result of the chassis controller and the lasting time reaches a preset duration. According to the brake signal fault detection system for the vehicle, the brake signals can be verified, and the fault of the brake signals can be reflected in time, so that the vehicle control unit can utilize the brake signals more securely.

    本发明公开了一种车辆的制动信号故障检测系统及方法,该系统包括整车控制器、底盘控制器和制动踏板,整车控制器和底盘控制器经由CAN总线连接,制动踏板包括电连接至底盘控制器的第一开关和电连接至整车控制器的第二开关,第一和第二开关能够相互独立地产生表征制动踏板的动作的第一和第二制动信号,底盘控制器能够判断制动踏板的状态并将判断结果发送至整车控制器,整车控制器能够判断制动踏板的状态,并在自身的判断结果与底盘控制器的判断结果不同且持续时长达到预设时长时发出制动信号故障预警。根据本发明的车辆的制动信号故障检测系统能够对制动信号进行校验并及时反映制动信号的故障,从而使得整车控制器得以更有保障地利用制动信号。
