Abstract
Steering angle for rear wheels of a vehicle is controlled by determining a rear wheel steering angle in a preselected relation to a steered angle of a steering wheel. A correction factor for the rear wheel steering angle is based on a difference in rotational speed between front and rear wheels induced during turning. The correction factor for rear wheel steering angle is maintained at the value it had prior to braking to cancel the effect of braking slips on the determination of the rear wheel steering angle to improve steering stability.
