A control system comprises a clutch for limiting a differential action between left and right drive wheels or varying a driving torque distribution between front and rear drive axles of a four wheel drive vehicle, a sensor group and a controller for controlling an engagement force of the clutch to control the differential limiting force or the torque distribution. The sensor group senses a decelerating condition of the vehicle, a vehicle lateral acceleration and a vehicle speed. The controller increases the clutch engagement force, so as to restrain tack-in, in accordance with the lateral acceleration when the vehicle is in a decelerating operation and the lateral acceleration is high. When the vehicle speed increases, the controller increases a rate of increase of the clutch engagement force with respect to the lateral acceleration to improve both of a high speed cornering stability and a low speed steering response.
