The invention discloses an automobile acceleration deviation control method. The method specifically comprises the steps that firstly, the rotating speed n1 of a left output shaft is collected from arotating speed sensor in real time; then the left and right front wheel height sensors are used for collecting the distance between the wheels and the vehicle body, the real-time positions of the wheels relative to the vehicle body are calculated, and therefore the real-time included angle alpha R between the short axis and the horizontal plane and the real-time included angle alpha L between thelong axis and the horizontal plane are calculated according to the lengths of the long axis and the short axis and installation position parameters; and finally, a motor rotating speed value is calculated according to a calculation formula of the motor output rotating speed v, after the rotating speed of the motor is adjusted to the calculated value by using the controller, the rotating speed andthe torque output to the long axis can be regulated and controlled. The torque difference between the left half shaft and the right half shaft on the original vehicle is eliminated, the problem of deviation during sudden acceleration during starting or driving of the vehicle is solved, and the driving safety is improved.

    本发明公开一种汽车加速跑偏控制方法,具体是需首先从从转速传感器实时采集左输出轴的转速n1;再利用左、右前轮高度传感器采集车轮相对于车身的间距,计算出实时的车轮相于车身的位置,从而根据长、短轴的长度及安装位置参数,计算出实时的短轴与水平面间的夹角αR以及长轴与水平面间的夹角αL;最后根据电机输出转速v的计算公式计算出电机转速值,利用控制器将电机转速调整至计算得出的值后,即可使得输出到长轴的转速、转矩得到调控,从而消除原车上左、右半轴之间的扭矩差,以解决汽车起步或行驶中突然加速时跑偏的问题,提升行车安全。
