The invention provides a brake switch fault diagnosis method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a stroke parameter of a brake switch; acquiring a switching signal generated based on the stroke parameter of the brake switch, wherein the switching signal comprises a first path of switching signal and a second path of switching signal; judging whether the current position of the brake switch is located in a preset interval range or not based on the stroke parameter; when the current position is located in the preset intervalrange and the first path of switching signal and the second path of switching signal are not synchronous, starting timing from entering the preset interval range, counting when timing exceeds a presetfirst timing threshold value, and when counting reaches a preset first counting threshold value, judging that the brake switch breaks down. The problems that when two paths of physical signals of thebrake switch are located in an on-off point switching area, due to the fact that a driver steps on a pedal habitually, on-off of the brake switch is not synchronous, the holding time is longer than the diagnosis time, and false alarm faults occur are solved.
本发明提供一种制动开关故障诊断方法、装置、电子设备和存储介质,方法包括:获取制动开关的行程参数;获取基于所述制动开关的行程参数所产生的开关信号,所述开关信号包括第一路开关信号和第二路开关信号;基于所述行程参数判断所述制动开关的当前位置是否位于预设区间范围内;当所述当前位置位于所述预设区间范围内且所述第一路开关信号和第二路开关信号不同步时,从进入所述预设区间范围开始计时,当所述计时超过预设第一计时阈值时计数,当所述计数达到预设第一计数阈值时,判定所述制动开关故障。本发明解决了制动开关两路物理信号处于通断点切换区域时,由于驾驶员习惯性踩下踏板,出现制动开关通断不同步且保持时间大于诊断时间的误报故障问题。
