Motor-driven power steering apparatus
First Claim
1. A motor-driven power steering apparatus for converting rotation of an electric motor into a linear stroke of a rack shaft by a power transmission mechanism and steering a wheel coupled to the rack shaft, comprising:
- an automatic neutral restoring means for judging a vehicle stop and a manual steering rest, and for rotating the electric motor in such a manner as to restore a detected steering angle of a steering angle sensor to a neutral position so as to execute an automatic steering, when the steering angle is out of the neutral position.
