ABSTRACT:
Apparatus for controlling the steerable wheels of a power-assisted steering unit of a vehicle in which an angle detector is connected to the power assist unit and to a power controller. An abnormality detector is arranged between the steering shaft of the steering wheel and an output shaft of the angle detector to detect an abnormal state based on relative displacement of the steering shaft and the output shaft of the angle detector to produce a signal which is sent to the power controller. The steering shaft is controlled by the power controller to avoid the abnormal state based on the signal from the abnormality detector, a control signal from an electronic control unit based on steering angle of the wheels and a signal from a sensor detecting steering angle of the steering wheel.
