Abstract
The torque distribution for four wheels is controlled correspondingly to the turning state of a car. In this case, a target yaw rate is determined on the basis of a steering angle and a car speed so that the torque distribution ratio of right and left wheels is set. Consequently, the turning of the car can be improved. In addition, a quantity of drivers' steering can be prevented from being excessively increased during turning.
