ABSTRACT:
A four wheel drive system of a vehicle including a power plant for producing driving force, has a front wheel driving mechanism for transmitting the driving force to drive a right and left front wheels and rear wheel driving mechanism for transmitting the driving force to drive right and left rear wheels. Right and left wheel clutches provided in one of the driving mechanisms for control the amount of the driving force transmitted to the wheels, and steering angle detecting device detects a steering angle of a steering wheel. A control device increases torque distribution for the rear wheel driving mechanism in a cornering condition of the vehicle as a steering angle change rate is increased. The system provides the vehicle with a desirable torque distribution during a cornering operation so that improved cornering property is obtained.
