舵制御装置。[Scope of Claim for Utility Model Registration] A rear wheel steering mechanism that steers the rear wheels in conjunction with the steering of the front wheels, a brake operation detection means that detects the operated state and non-operated state of the parking brake, and a brake operation detection means based on the brake operation detection means. The rear wheel steering mechanism is controlled in accordance with the detection of the operating state and the non-operating state of the parking brake, and in a first state, the rear wheel steering mechanism is set to a non-operating state, and in a second state, the rear wheel steering mechanism is set to an operating state. A rear wheel of a front and rear wheel steered vehicle, comprising a switching means, which sets the rear wheel steering mechanism to a non-operating state when a parking brake is operated, and sets the rear wheel steering mechanism to an active state when the parking brake is not operated. In the steering control device, the vehicle speed detection means detects the vehicle speed, and when the operation state of the parking brake is detected by the brake operation detection means, the vehicle speed detected by the vehicle speed detection means becomes larger than a predetermined first vehicle speed. a first switching control means for switching the switching means in the first state to a second state under the condition that when the operation of the parking brake is detected by the brake operation detection means, the vehicle speed detected by the vehicle speed detection means is and a second switching control means for switching the switching means in the second state to the first state on the condition that the vehicle speed becomes smaller than a second vehicle speed, which is smaller than the first vehicle speed. rear wheel steering control device.
