ABSTRACT:
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 axles of a 4WD 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 between the front and rear drive wheels. The sensor group includes an accelerator position sensor and a lateral acceleration sensor. The controller increases the clutch engagement force as the speed of increase of the accelerator opening degree increases, and increases the rate of increase of the clutch engagement force with respect to the increasing speed of the accelerator opening degree when the lateral acceleration increases.
