The invention discloses an abnormality diagnosis method and device for a brake pedal, and the method comprises the steps: recognizing the signal change of a switch state sensor of the brake pedal in real time after a vehicle is started; when the signal change is identified, updating a signal jitter identification parameter of a current preset anomaly identification period based on a corresponding signal change feature; and whether the brake pedal is abnormal or not is judged based on the signal jitter identification parameters and the duration when all the signals of the switch state sensor are located at the same level. According to the method and the device, the abnormal condition of the brake pedal is identified based on the signal change condition of the on-off state sensor of the brake pedal, and the abnormal condition of the brake pedal without a brake pedal depth sensor can be accurately diagnosed.

    本申请公开了一种制动踏板的异常诊断方法和装置,其中方法包括:在车辆启动后,实时识别制动踏板的开关状态传感器的信号变化;当识别到所述信号变化时,基于相应的信号变化特征,更新当前预设异常识别周期的信号抖动识别参数;基于所述信号抖动识别参数和所述开关状态传感器的所有信号处于相同电平的持续时长,判断所述制动踏板是否发生异常。本申请,通过基于制动踏板的开关状态传感器的信号变化情况,识别制动踏板的异常情况,可以对没有配置制动踏板深度传感器的制动踏板,进行准确地异常诊断。
