control a turning motor that generates a turning force for causing turning wheels, of which power transmission to and from a steering wheel is cut off, to turn;
change a steering angle ratio according to a vehicle speed through control of the turning motor, wherein the steering angle ratio is a ratio of a turning angle of the turning wheels to a steering angle of the steering wheel; and
change, when the steering wheel is being held at a constant steering angle with respect to a neutral position or when the vehicle is turning, a degree of change of the steering angle ratio with respect to the vehicle speed due to acceleration or deceleration of the vehicle.
