Abstract
A yaw moment control apparatus for a vehicle which comprises a rear wheel driving torque transmission path that transmits the driving torque of a drive unit to left and right rear wheels, the path including a speed increasing device for increasing speed of the rear wheels relative to the front wheels, and clutches that change transmission capacities of driving torques to the left and right rear wheels, and a control unit for controlling fastening forces of the clutches. The control unit controls the fastening forces based on a lateral acceleration of the vehicle to impart a yaw moment by a driving torque difference between the wheels to the vehicle when traveling control of the vehicle by applying braking forces to the wheels is not being performed, and to impart no yaw moment by a driving torque difference to the vehicle when traveling control of the vehicle is being performed.
