Abstract
A system for controlling a steering angle for the rear wheels of a vehicle is provided. This system includes generally, a torque sensor for detect torque of driven wheel, an angle sensor for sensing a steered angle of front wheels, a steering controller for determining a rear wheel target steering angle, and an actuator for steering the rear wheels by the rear wheel target steering angle. The steering controller first determines a rear wheel steering angle based on the steered angle of the front wheels and then calculates a correction for the rear wheel steering angle according to variation in the torque of the driven wheels during running to determine the proper rear wheel target steering angle.
