摘  要:
推导了车轮抱死过程中的轮角速度特征,通过小波分析的方法,利用轮角速度信号导数的间断特性,获取最佳滑移率的发生时刻,从而得到最佳滑移率,通过1/4车辆模型仿真验证了该方法的正确性。

摘  要:
The characteristic of wheel speed during locking was derived.By the means of wavelet,using the discontinuity of the derivative of wheel angle speed,the time when the optimal slip ratio comes into being was obtained.Thus we can get the optimal slip ratio.The method was proved using a 1/4 vehicle model.
