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.

Abstract: A vehicle turning control device mounted on a vehicle includes a control device that calculates a control yaw moment for increasing turning performance of the vehicle and uses a yaw moment generation device to generate the control yaw moment. A limit control yaw moment, which is an upper limit of an allowable range of the control yaw moment in which the vehicle does not spin, is a function of a lateral jerk equivalent and decreases as the lateral jerk equivalent increases. The control device calculates the limit control yaw moment based on the lateral jerk equivalent and the function, updates a hold control yaw moment with a latest value of the limit control yaw moment when the latest value is less than the hold control yaw moment, and determines the control yaw moment so as not to exceed the hold control yaw moment.
