电动汽车制动踏板诊断方法及装置
摘要：
一种电动汽车制动踏板诊断方法及装置，所述诊断方法包括：获取第一制动踏板开关状态和第二制动踏板开关状态；判断所述第一制动踏板开关状态与所述第二制动踏板开关状态是否相同；当所述第一制动踏板开关状态与所述第二制动踏板开关状态不同时，获取连续N次制动踏板操作过程中，对应的第一制动踏板开关状态以及第二制动踏板开关状态，一次制动踏板操作为一次踩下制动踏板后松开制动踏板的操作；当连续N次制动踏板操作过程中，对应的所述第一制动踏板开关状态与所述第二制动踏板开关状态均不完全相同时，判定所述制动踏板出现故障。采用所述方法及装置，可以有效地减少制动踏板故障误报，从而降低行车安全隐患。
摘要（英）：

The invention discloses an electric vehicle brake pedal diagnosing method and device. The diagnosing method comprises the steps that the on-off state of a first brake pedal and the on-off state of a second brake pedal are obtained; whether the on-off state of the first brake pedal and the on-off state of the second brake pedal are the same or not is judged; when the on-off state of the first brake pedal is different from the on-off state of the second brake pedal, the corresponding on-off state of the first brake pedal and the on-off state of the second brake pedal in a continuous N-time brake pedal operation process are obtained, and one time of brake pedal operation is once operation for treading the brake pedals and then loosening the brake pedals; and when the corresponding on-off state of the first brake pedal and the on-off state of the second brake pedal are not exactly the same in the N-time brake pedal operation process, the judgment that the brake pedals break down is made. By the adoption of the method and device, misinformation of brake pedal failure can be effectively reduced, so that traffic potential safety hazards are reduced.
