Abstract
In a steering apparatus for a vehicle which has a steering mechanism for steering steerable road wheels by means of a steering wheel operated by a driver and an electrically controllable auxiliary steering angle superposition mechanism, and in which a target auxiliary steering angle is set in accordance with a steering wheel angle, and an electric motor of the auxiliary steering angle superposition mechanism is driven and controlled according to the target auxiliary steering angle, the rotation of the electric motoris inhibited without regard to the state of the driving control. A short-circuit relayis provided for short-circuiting opposite terminals of the electric motor, and the short-circuit relayis operated so as to short-circuit the opposite terminals of the electric motorthrough a short-circuit relay driving unitin accordance with the kind of a failure detected by a failure detection unit, whereby the rotation of the electric motoris inhibited. In addition, when a power supply to the steering apparatus for a vehicle is interrupted, the short-circuit relayoperates, without power supply, to short-circuit the opposite terminals of the electric motor
