ABSTRACT:
A fail-safe steer angle control system includes a front auxiliary steering actuator for controlling a front wheel steering angle in response to a front control signal representing a front wheel auxiliary steering angle, a rear wheel steering actuator for controlling a rear wheel steering angle in response to a rear control signal, a steering angle sensor for sensing the steering wheel angle, and a controller which produces the front control signal based on the steering wheel angle in accordance with a predetermined first relationship, and produces the rear control signal based on the steering wheel angle in accordance with a predetermined second relationship. The controller has a fail-safe section which adjusts the first or second relationship when an abnormal condition is detected in either the front steering system or the rear steering system.
