ABSTRACT:
A yaw moment control system for a vehicle is provided to prevent the reduction of the turning performance during traveling of a vehicle at a low speed, which is designed, so that a driving force and a braking force are distributed to inner and outer wheels during turning of the vehicle in order to eliminate an over-steering tendency produced upon deceleration of the vehicle during turning thereof, thereby enhancing the stability during traveling of the vehicle at a high speed. A longitudinal acceleration Xg calculated in a longitudinal acceleration calculating circuit, a lateral acceleration Yg calculated in a lateral acceleration calculating circuit and a correcting factor Kv determined in a correcting factor determining circuit are multiplied by a control amount calculating circuit. Torque proportional to the resulting product is distributed to left and right wheels to eliminate the over-steering tendency produced upon deceleration of the vehicle during the turning thereof. When the vehicle is being decelerated and the vehicle speed V is smaller, the correcting factor Kv assumes a value smaller than 1.0, and at the other time, the correcting factor Kv assumes a value of 1.0. Therefore, when the vehicle is traveling at a low vehicle speed, an under-steering tendency can be prevented from being produced by the distribution of the torque, thereby preventing the reduction in turning performance.
