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.
