Abstract
A torque distribution control system for a four-wheel drive vehicle has an engine output controller which controls the output of the engine of the vehicle, a braking controller which separately controls the braking forces applied to the left wheels and the right wheels and/or the braking forces applied to the front wheels and the rear wheels. A torque distribution changing system determines the torque distribution to the wheels according to the running condition of the vehicle and controls the braking controller and the engine output controller to apply a braking force to one of the front wheels and the rear wheels or one of the left wheels and the right wheels and to increase the output of the engine by an amount substantially corresponding to the braking force applied to the one of the front wheels and the rear wheels or the one of the left wheels and the right wheels so that the torque distribution determined according to the running condition of the vehicle can be obtained.
