A rear wheel steer angle control system for a vehicle includes a vehicle speed sensor, a steering wheel angle sensor and a controller for controlling a rear wheel steer angle delta r(s) with respect to a front wheel steer angle delta f(s) in accordance with delta r(s)/ delta f(s)=(K+Tls)/(1+T2s), where K, T1 and T2 are control parameters each of which is a function of the vehicle speed, and includes a quantity representing a distance of a zero sideslip angle position from a center of gravity of the vehicle. The quantity representing the distance of the zero sideslip angle position at which the sideslip angle is to be zero, may be fixed at a constant value, or may be adjusted in accordance with any one or more of the vehicle speed, the steering wheel angle and the time rate of change of the steering wheel angle.
