The invention relates to a clamping stagnation detection method and device for a vehicle accelerator pedal and a vehicle. The clamping stagnation detection method for the vehicle accelerator pedal comprises the steps that a first cache difference value of a first opening signal and a second cache difference value of a second opening signal of the vehicle accelerator pedal are obtained; wherein the pedal range corresponding to the first opening signal is smaller than the pedal range corresponding to the second opening signal, and the first cache difference value is the difference value between the first opening cache value at the first preset moment and the first opening cache value at the second preset moment; the second cache difference value is a difference value between a second opening cache value at a third preset moment and a second opening cache value at a fourth preset moment; and the clamping stagnation state of the first opening signal and the clamping stagnation state of the second opening signal are judged according to the ratio of the first cache difference value to the first threshold value and the ratio of the second cache difference value to the first threshold value. According to the technical scheme, the problem of false alarm of the two-way clamping stagnation state of the accelerator pedal is avoided, and the accuracy of clamping stagnation state detection is improved.
本公开涉及一种车辆加速踏板的卡滞检测方法、卡滞检测装置及车辆,车辆加速踏板的卡滞检测方法包括:获取车辆加速踏板的第一开度信号的第一缓存差值和第二开度信号的第二缓存差值;其中,第一开度信号对应的踏板量程小于第二开度信号对应的踏板量程,第一缓存差值为第一预设时刻的第一开度缓存值与第二预设时刻的第一开度缓存值的差值,第二缓存差值为第三预设时刻的第二开度缓存值与第四预设时刻的第二开度缓存值的差值;根据第一缓存差值与第一阈值的比值和第二缓存差值与第一阈值的比值判断第一开度信号的卡滞状态和第二开度信号的卡滞状态。通过本公开的技术方案,避免了加速踏板双路卡滞状态误报的问题,提高了对卡滞状态检测的准确性。
