A driving torque distribution control system for a four wheel drive vehicle includes a torque distributing clutch provided in a drive path for the front wheels, and a controller for controlling a driving torque transmitted to the front wheels through the clutch, in accordance with a corrected front and rear wheel speed difference which is a difference resulting from subtraction of a dead band from a sensed actual front and rear wheel speed difference. In order to improve the controllability near the cornering limits of the vehicle without deteriorating the driving ability in a low lateral acceleration cornering operation, the controller sets the dead band so that the dead band increases as the lateral acceleration of the vehicle increases.
