A target relative rotation angle of automatic steering is calculated; a target current for assist steering during automatic steering is calculated based on the sum of a torque that inhibits a reaction force of the automatic steering from acting on a steering wheel, a torque that cancels out torque that acts resulting from self-aligning torque of the steered wheels, and a torque according to a steering angle; a target current for assist steering to reduce a steering load on a driver is calculated; a weight of the target current is calculated to increase as the target relative rotation angle increases; and an electric power steering unit is controlled, with a weight sum of the target currents as a final target current.
