Abstract
In a four wheel drive vehicle adapted to drive all of the four wheels, a braking force is applied to the wheel which causes slipping while the output torque of the engine is increased in accordance with brake operation. A braking pressure adjusting unit is preferably provided with each of the four wheels which is arranged so as to separately and individually brake the wheel which slips.
