A control steered angle calculation unit includes: an end position determination unit that determines whether a rack shaft is located at either one of right and left rack end positions; a motor absolute angle calculation unit that detects a motor absolute angle; an end position-corresponding motor angle setting unit that, when the rack shaft is determined to be located at either one of the right and left rack end positions, sets the detected motor absolute angle as an end position-corresponding motor angle corresponding to the one of the right and left rack end positions; and a control steered angle origin setting unit that calculates an average value of right and left end position-corresponding motor angles as an offset angle, and sets an angle obtained by subtracting the offset angle from the detected motor absolute angle as an origin of the control steered angle represented by the motor ab solute angle.
