Claims

[Scope of utility model registration request]

In a four-wheel steering vehicle capable of steering rear wheels in opposite phase and in phase, a front wheel and rear wheel steering angle detection means, a vehicle speed detection means, a yaw rate detection means, and a same/inverse phase switching means are provided, and when the rear wheels are in phase, the vehicle speed detection means, front wheel steering A rear wheel rudder for a vehicle, comprising a control means for calculating a rear wheel target steering angle so that the yaw rate becomes zero based on a signal from an angle detecting means and a vehicle model, and outputting the calculated value to a rear wheel drive actuator. Angle control device.
