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; when the ratio of the first cache difference value to a third threshold value is smaller than a numerical threshold value and the ratio of the second cache difference value to a second threshold value is larger than the numerical threshold value, it is judged that the first opening degree signal is in a clamping stagnation state; when the ratio of the first cache difference value to a first threshold value is larger than a numerical threshold value and the ratio of the second cache difference value to a third threshold value is smaller than the numerical threshold value, it is judged that the second opening degree signal is in a clamping stagnation state; wherein the second threshold value is larger than the first threshold value, and the third threshold value is smaller than the first threshold value. According to the technical scheme, the problem of false alarm of the 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;当所述第一缓存差值与第三阈值的比值小于数值阈值并且所述第二缓存差值与第二阈值的比值大于数值阈值判断所述第一开度信号为卡滞状态,以及当所述第一缓存差值与第一阈值的比值大于数值阈值并且所述第二缓存差值与第三阈值的比值小于数值阈值时,判断所述第二开度信号为卡滞状态;其中,第二阈值大于第一阈值,第三阈值小于第一阈值。通过本公开的技术方案,避免了加速踏板卡滞状态误报的问题,提高了对卡滞状态检测的准确性。
