ABSTRACT:
An electric power steering apparatus comprises a control unit which controls a motor drive for driving an electric motor on the basis of an steering torque signal. The control unit has an assist inhibitor for inhibiting the feed of an assist torque by the motor to a steering system under given conditions. The assist inhibitor inhibits the generation of the assist torque by the motor when the direction of a manual steering torque and the direction of the assit torque are inconsistent for more than a predetermined time period. As a result, it becomes possible to exhibit desired damper effect during the predetermined time period and to inhibit the feed of the assist torque by the motor to the steering system after lapsing of the predetermined time period.
