While a steering angle speed which represents a steering speed of the steering wheel is equal to or smaller than a predetermined speed, i.e., while the vehicle is making a steady turn with the steering wheel being held at a given angle or while the vehicle is running straight, when the rate of change of a rack load calculated by a rack load rate-of-change calculator becomes equal to or greater than a predetermined value, an EPS motor is supplied with a corrective current or which serves as a corrective signal for a drive signal in a direction to cancel out the rate of change of the rack load.
