Abstract
A steering system includes a steering shaft; a motor configured to generate a torque applied to the steering shaft; and a control unit configured to control the motor. The control unit has a function of performing steering angle feedback control for causing a steering angle that is a rotation angle of a steering wheel to reach a target steering angle that is set based on a point of view of adjusting a rotational position of the steering wheel, as an adjustment process of adjusting the rotational position of the steering wheel. The control unit is configured to set a limit value for limiting a change range of the target steering angle with respect to the steering angle at each moment in a period in which automatic rotation of the steering wheel is hindered in a case where the automatic rotation is hindered while the adjustment process is being performed.
