両の後輪舵角制御装置。[Scope of Claim for Utility Model Registration] 1. In a vehicle having a mechanism that steers the rear wheels according to the front wheel steering angle and vehicle speed, the rear wheels are steered from a rear wheel steered state to a non-steering state, or from a rear wheel non-steering state to a rear wheel steered state. A rear wheel steering angle control device for a vehicle, characterized in that when at least one state transition is made, the rear wheel steering angle is steered with a time constant set by a time constant means. 2. The time constant T1 of the rear wheel steering performed as the state changes depending on the vehicle speed is set larger than the time constant T2 of the rear wheel steering performed as the state changes with the front wheel steering angle condition. A rear wheel steering angle control device for a vehicle as claimed in Claim 1 of the Utility Model Registration Claim. 3. The rear wheel steering angle of the vehicle according to claims 1 and 2, wherein the time constants T 1 and T 2 are functions of the temporal change in vehicle speed and the rate of change of the front wheel steering angle, respectively. Control device.
