  • Patent number: 5053966
    Abstract: A motor control apparatus for an electric power steering system having a torsion torque sensor for detecting a torsion torque of the steering system of a vehicle, a command signal generating unit for generating a command signal in accordance with the torsion torque detected by the torque sensor, and a motor control unit for driving and controlling a motor of the electric power steering system in accordance with the command signal. The improvement of this invention is to assist steering force within the steering wheel correcting range. A steering speed detecting unit is provided for detecting the steering speed. The output signal from the steering speed range detecting unit is supplied to the steering wheel correction command unit which generates an assist correction signal. The assist correction signal has a characteristic that the absolute value thereof takes a predetermined value when a small steering angle range is detected.
