The microcomputer included in the steering control unit calculates a basic assist component that is a component of the assist force, on the basis of the steering torque. The microcomputer calculates a damping compensation component that suppresses a sudden change in a rotation angle, on the basis of a rotational angular velocity that is a time rate of change of the rotation angle. The microcomputer calculates, independently of the damping compensation component, a return compensation component that suppresses influence of the damping compensation component, on the basis of the rotational angular velocity. The microcomputer compensates the basic assist component by using both the damping compensation component and the return compensation component, in a situation where the steering wheel comes back to the neutral position without a steering operation that a driver performs to return the steering wheel.
