The invention belongs to the technical field of vehicle control, and provides a control method and system for preventing mistaken stepping of an accelerator pedal of a pure electric vehicle, when preset conditions are met for mistaken stepping prevention control, on the basis of judging that the opening degree and the opening degree change rate of the accelerator pedal reach the preset conditions, the single-side head rotation angle and the vehicle speed standard deviation of a driver are calculated; then, judging whether the driver has a lane changing overtaking intention or not according to the single-side head rotation angle of the driver and the vehicle speed standard deviation; if the driver has the lane-changing overtaking intention, judging that the driver is not stepped by mistake, and controlling the vehicle to execute power output, otherwise, judging that the driver is stepped by mistake, and controlling the vehicle not to execute power output; according to the method, the lane changing overtaking intention of the driver is added and judged, the non-mistaken stepping behavior of the driver is recognized, the problem of misjudgment caused by the influence of overtaking on the speed pedal opening degree and the opening degree change rate is solved, and the problem that behavior misjudgment is likely to be caused by the mode that only the pedal threshold value is set is solved.

    本发明属于车辆控制技术领域,提供了一种纯电动汽车加速踏板防误踩控制方法及系统,在满足预设条件进行防误踩控制时,在判断加速踏板开度及开度变化率达到预设条件基础上,计算驾驶员单侧头部转动角度及车速标准差;然后,依据驾驶员单侧头部转动角度及车速标准差判断驾驶员是否具备换道超车意图;如果驾驶员具备换道超车意图,判定为非误踩行为,控制车辆执行动力输出,否则,判定为误踩行为,控制车辆不执行动力输出;通过添加判断驾驶员的换道超车意图,对驾驶员非误踩行为进行了识别,解决了超车对速踏板开度与开度变化率影响造成的误判问题,以及解决了仅通过设置踏板阈值的方式容易造成行为误判的问题。
