The invention discloses a method for monitoring the state of an automobile brake pedal. Two switch electric signals of the brake pedal and pressure signals of a brake master cylinder are detected in real time; the adhesion state of the brake pedal is judged according to the two-way switch electric signals; the braking state of the vehicle is judged according to the braking master cylinder pressure signal; a braking state of the brake pedal is determined based on the adhesion state of the brake pedal and a braking state of the vehicle. According to the invention, two paths of redundant brake pedal switching signals and brake master cylinder pressure signals are simultaneously used as the input of the brake state used by ECU calculation, so that the monitoring of the brake pedal state signals is realized; the braking state of the vehicle for driving control can still be kept in a safe state, and the threat of the signal fault of the brake pedal to the driving safety of the vehicle is avoided.

    本发明公开了一种汽车制动踏板状态监控方法,实时检测制动踏板的两路开关电信号及制动主缸压力信号;根据两路开关电信号判断制动踏板的粘连状态;根据制动主缸压力信号判断车辆的制动状态;基于制动踏板的粘连状态和车辆的制动状态确定制动踏板的制动状态。本发明通过两路冗余的制动踏板开关信号和制动主缸压力信号同时作为ECU计算使用的制动状态的输入,实现制动踏板状态信号的监控,该方案可在某些通道发生故障或信号传递失效时,仍能使车辆用于行驶控制的制动状态保持在较为安全的状态,避免制动踏板信号故障对车辆行驶安全的威胁。
