Abstract
A steering control device includes a control unit configured to control at least an operation of a steering-side motor. The control unit is configured to calculate a target reaction torque; calculate a difference axial force that is used to limit steering for turning the turning wheels in a predetermined direction, the difference axial force being reflected in the target reaction torque; and set a reference angle to one of a steering angle and a turning angle, set a converted angle to an angle obtained by converting another of the steering angle and the turning angle according to a steering angle ratio, and calculate the difference axial force based on a difference between the reference angle and the converted angle.
