The invention discloses a fault diagnosis method and device for a vehicle brake switch and a vehicle. The method comprises the steps that a brake switch signal used for determining the state of a brake pedal and a brake depth signal used for determining the brake depth corresponding to the rotation angle of the brake pedal are obtained; wherein when the brake switch is normal, the state of the brake pedal and the brake depth meet the brake logic of the vehicle; and when the brake switch signal and the brake depth signal do not meet the brake logic of the vehicle, a brake switch fault is diagnosed. According to the invention, fault diagnosis of the brake switch is carried out through the coupled brake switch signal and the brake depth signal, so that the accuracy of fault diagnosis of the brake switch can be effectively improved.
本发明公开车辆制动开关的故障诊断方法、装置及车辆,其中方法包括:获取用于确定制动踏板状态的制动开关信号和用于确定制动踏板的转角对应的制动深度的制动深度信号;其中,制动开关正常时,制动踏板状态与制动深度满足车辆的制动逻辑;在所述制动开关信号与所述制动深度信号不满足车辆的制动逻辑时,诊断为制动开关故障。本发明通过耦合的制动开关信号和制动深度信号,进行制动开关的故障诊断,能够有效提高制动开关的故障诊断的准确性。
