Claims

[Scope of utility model registration request]

A rear wheel steering control device for a vehicle, comprising a power cylinder controlled by the operation of a hydraulic pressure adjustment valve based on steering of a steering wheel, and an actuator that steers the rear wheels using power steering pressure oil acting on the power cylinder, A switching valve is provided in a hydraulic circuit that supplies the power steering pressure oil to the actuator, and the switching valve has a neutral position that cuts off the supply of the power steering pressure oil to the actuator, and a neutral position that cuts off the supply of the power steering pressure oil to the actuator. A pressure sensor is provided which has an operating position for supplying oil and detects a pressure difference of the power steering pressure oil flowing through the hydraulic circuit between the switching valve and the power cylinder, A rear wheel steering control device for a vehicle, characterized in that the rear wheel steering control device is configured to switch the switching valve to steer the rear wheels in a direction opposite to the steering direction of the steering wheel.
