ABSTRACT:
A yaw moment control system is provided to eliminate an under-steering tendency generated due to the insufficiency of a cornering force of front driven wheels of a vehicle. More specifically, in place of a longitudinal acceleration Xg and a lateral acceleration Yg used for calculating the amount of torque distributed, a corrected longitudinal acceleration Xg' larger than the value directly proportional to the longitudinal acceleration Xg and a corrected lateral acceleration Yg' larger than the value directly proportional to the lateral acceleration Yg are used, thereby increasing the amount of torque distributed to between inner and outer wheels during turning of the vehicle. A yaw moment is generated which is directed inwards in the turning direction to prevent the under-steering tendency which is generated due to the insufficiency of the cornering force of the front wheels.
