Abstract
It is a purpose of the present invention to connect the operation of the driving-force distributing device with the operation of the driving-force reducing device at an appropriate timing to insure a stable performance of the vehicle. When a slip rate exceeds a predetermined value, a driving-force distributing device which includes a variable differential operation limiting device is first operated so as to hold a differential operation limiting torque at a predetermined value. If the slip rate further increases, a driving-force reducing device which includes a traction control device is operated so as to hold the engine output at a predetermined value. At that time, if slip rates of both racing inner wheel and racing outer wheel are further increased, the driving-force reducing device is operated to reduce the engine output.
