Abstract
In a vehicle steering system provided in a vehicle in which a high-voltage battery is provided, a clutch mechanism is mechanically disconnected and the intermediate shaft falls, after a collision of the vehicle is detected. An ECU detects the collision of the vehicle based on an acceleration that is input, and then detects contraction of the column shaft and disconnection of the clutch mechanism based on an ON signal of a microswitch. Thereafter, the ECU is able to continue to rotationally drive an electric motor based on a steering angle signal that is output from a steering angle sensor provided on the column shaft, and that is electrically insulated through a photo coupler, and thus the ECU causes the vehicle to travel and stop.
