DEVICE FOR CONTROLLING TORQUE DISTRIBUTION TO LEFT AND RIGHT WHEELS ON A VEHICLE

When a rear wheel total drive force TcLR is smaller than a rear wheel drive force difference TcLR and the rear wheel drive force difference TcLR cannot be accomplished by dividing the rear wheel total drive force TcLR between the left and right rear wheels, an inside wheel target drive force TcIN is not set to 0 and an outside wheel target drive force TcOUT is not set to TcLR. Instead, the inside wheel target drive force TcIN is set to a default drive force TcMIN that is a minimum value required to prevent a three-wheel drive state from occurring, and the outside wheel target drive force TcOUT is set a value equal to the sum of the default drive force TcMIN and the rear wheel drive force difference TcLR, which is a value with which the rear wheel drive force difference TcLR can be achieved under the condition of the inside wheel target drive force TcIN being equal to the default drive force TcMIN. As a result, even if the condition TcLR < TcLR exists, the vehicle will not enter a three-wheel drive state and the turning stability can be improved.
