Abstract
A four-wheel steer control device has an actuator for actuating a set of steerable rear wheels for controlling the positions of the rear wheels by the operation of the actuator. A slip control device for a differential has a clutch for supplying a variable slip limiting force to the differential to limit a differential action thereof variably. An integrated control system controls the four-wheel steer control device and the slip control device in such a way that the rear wheels are correctively steered in the direction opposite to that of the front wheels at the time of cornering of the vehicle and when the slip limiting force is larger than a predetermined value and a cornering outside driving wheel speed is faster than a cornering inside driving wheel speed.
