Abstract: In a steer by wire and idle stop vehicle, idle stop conditions for invoking an idle stop operation include that the traveling speed of the vehicle has fallen below a first value (10 km/h). When the vehicle speed is lower than the first value but higher than a second value (5 km/h), a steering actuator control unit 44 executes a position keep control whereby a steering motor 29 is electrically braked, and a reaction force actuator control unit 43 operates a reaction force motor 26 as a dynamic brake. When the vehicle speed has fallen below the second value in the idle stop operation, the steering motor control unit terminates the position keep control.
