ことを特徴とする４輪操舵車両の後輪操舵装置。 A front wheel steering angle sensor that detects at least a front wheel steering angle, a vehicle speed sensor that detects vehicle speed, and a control unit that performs rear wheel steering control based on the front wheel steering angle and vehicle speed detected by the front wheel steering angle sensor and the vehicle speed sensor, In a four-wheel steering vehicle having a rear wheel steering actuator, a means for detecting front wheel steering force or front wheel lateral force is provided, and rear wheel rotation is performed based on information that the front wheel steering force or front wheel lateral force detected by the means is almost zero. A rear wheel steering system for a four-wheel steering vehicle, characterized in that the control unit is provided with front wheel neutral point correction logic for determining the zero point of the front wheel turning angle at which the steering angle is zero.
