A four-wheel drive vehicle has a transmission, main drive wheels operatively connected to an output shaft of the transmission, auxiliary drive wheels, and a transfer clutch for transmitting output of the transmission to the auxiliary drive wheels. A control system is provided with a detector for detecting the ratio of front-wheel speed to the rear-wheel speed and for producing a speed ratio signal, which represents steering operation of the vehicle and for producing a steering angle signal. A control unit is responsive to the steering angle signal for controlling torque of the transfer clutch so as to slip the transfer clutch in dependence on the steering angle signal. |
