The invention discloses a method and system for eliminating reverse electromotive force of a motor, and the method comprises the steps: judging whether an automobile deviates or not through a zero switch in the running process of the automobile; if the automobile is in the off-tracking state, the position of a real-time steering motor is obtained through a motor encoder; judging whether the steering angle of the wheel is greater than a set angle; and in a non-turning state in the running process of the automobile, zero position adjustment is performed at any time. The problem of driving deviation caused by inaccurate steering of the driving wheels is solved, the operation difficulty of driving straight lines through motor steering is greatly reduced, and real-time correction can be carried out in the automobile driving process. The method passes actual tests at present, and the effect is obvious.

    本发明公开了一种消除电机反向电动势的方法及系统,方法包括汽车行驶过程中,通过零位开关判断汽车是否跑偏;若汽车处于跑偏状态,通过电机编码器获得实时转向电机的位置;判断车轮的转向角度是否大于设定角度;在汽车行驶过程的非转弯状态下,时刻进行零位调整。本发明解决了驱动轮转向不准导致的行车偏差问题,极大降低了通过电机转向走直线的操作难度,且可以在汽车行驶过程中实时进行纠正。此方法目前已经通过实际测试,效果明显。
