Abstract
A system for controlling a steering angle of a vehicle, such as a steering angle of a rear steering wheel, the system having a yaw rate sensor for detecting a yaw rate of the vehicle, an actuator electrically controlled to change the steering angle of the vehicle, and a controller for controlling the actuator to control the steering angle on the basis of an input which includes at least a component derived from the detected yaw rate. The controller includes a detector for detecting an abnormality of a value of the yaw rate detected by the yaw rate sensor, and a limiter for limiting an amount of change in the steering angle to within a predetermined tolerable range when the abnormality is detected.
