Abstract:
1. A vehicle behavior control device comprising: steering-wheel-angle detecting means configured to detect a steering-wheel angle; yaw-rate detecting means configured to detect a yaw rate; vehicle-speed calculating means configured to determine a vehicle speed; sideslip prevention controlling means configured to prevent a sideslip by controlling a vehicle; and driving-force-distribution controlling means configured to control driving-force distribution with respect to at least left and right driving wheels, wherein the driving-force-distribution controlling means includes additional-yaw-moment setting means configured to set an additional yaw moment to be added to the vehicle and to determine a polarity of the additional yaw moment on the basis of the steering-wheel angle, the yaw rate, and the vehicle speed, and left-right driving-force distribution controlling means configured to set the driving-force distribution with respect to the left and right driving wheels on the basis of the additional yaw moment and the polarity of the additional yaw moment set and determined by the additional-yaw-moment setting means, and to adjust the driving-force distribution when an operation signal for sideslip prevention is output from the sideslip prevention controlling means, the driving-force distribution being adjusted such that the polarity of the additional yaw moment is in the same direction as that of a yaw moment applied by the sideslip prevention controlling means.
