Patent ID: 8087488

Claim:
A steering-by-wire-type steering apparatus for a vehicle, comprising: an input member connected to a steering wheel and displacing interlockedly with the steering wheel; an output member connected to turnable wheels and displacing interlockedly with the turnable wheels; a first electrical actuator connected to the input member and controlling displacement of the input member; a second electrical actuator connected to the output member and controlling displacement of the output member; a connecting-disconnecting device disposed between the input member and the output member, the connecting-disconnecting device operable in a disconnected state so as to separate the input member and the output member to thereby prevent power transmission therebetween, and in a connected state so as to connect the input member and the output member to thereby permit power transmission therebetween; and anomaly detection means for detecting an anomaly of the connecting-disconnecting device on the basis of a predetermined operation quantity which is input to the input member as a result of operation of the steering wheel by a driver, the operation quantity changing in accordance with the relation of relative displacement between the input member and the output member in each of the connected state and the disconnected state of the connecting-disconnecting device.
