ABSTRACT:
In a vehicle including a torque distributing device for distributing the torque of an engine to left and right driving wheels, a feed-forward control system determines a lateral distribution torque T.sub.1 from an engine torque T.sub.E, a number Ne of revolutions of the engine, a vehicle speed V and a steering angle .theta., and a feed-back control system determines a feed-back torque T.sub.F from a target yaw rate Y determined from the vehicle speed V and the steering angle .theta. and an actual yaw rate Yaw. A final distribution torque T is determined by adding the lateral distribution torque T.sub.1 and the feed-back torque T.sub.D at a predetermined ratio, and an actuator is driven to distribute the engine torque to the left and right driving wheels on the basis of the final distribution torque T. Thus, it is possible to appropriately distribute the engine torque to the left and right driving wheels, and to allow the actual yaw rate of the vehicle to be matched with the target yaw rate to improve the steering characteristic.
