A rear wheel steering control system is provided. This system includes a traction control system which is responsive to generation of a difference in rotational speeds between front and rear wheels to recover traction of driven wheels and a compensating system which corrects a rear wheel steering angle, determined in a preselected relation to vehicle speed and a steered angle of the front wheels, based on the difference in rotational speeds between the front and rear wheels to provide a proper rear wheel target steering angle. The system restricts operation of the compensating system during operation of a traction control system to prevent a hunting frequency thereof from affecting the operation of the compensating system.
