Abstract

In a method of controlling an electric power steering apparatus by controlling a drive force of a steering force assisting electric motor when a vehicle speed is lower than a predetermined speed and controlling a braking force of the electric motor when the vehicle speed exceeds the predetermined speed, a steering wheel forward or reverse turning state is determined in accordance with a change in steering torque when the vehicle speed exceeds the predetermined state. The braking force of the electric motor is controlled only when the steering wheel reverse turning state is detected.
