Abstract:
A vehicle stability control system includes a signal collection sensor and a vehicle controller ( 10 ). The signal collection sensor is configured to collect a vehicle condition information parameter, and the vehicle controller ( 10 ) is configured to calculate a control yaw moment according to the vehicle condition information parameter. The control yaw moment is used to cancel a difference between an estimated yaw moment and an actual yaw moment. The vehicle controller ( 10 ) is further configured to determine according to the vehicle condition information parameter whether the vehicle ( 100 ) is in a stable region or a non-stable region in the case of tire blow-out, and allocate the control yaw moment to four wheels ( 101 ) according to a vehicle stability condition, thus implementing vehicle stability control. A vehicle stability control method and a vehicle ( 100 ) with the vehicle stability control system are also disclosed.

Claim (Index 16):
The vehicle stability control method according to  claim 15 , wherein if \u0394\u03b3\u2264\u03b31 and \u03b2\u2264\u03b21 are satisfied, the vehicle is in the stable region; if \u0394\u03b3\u2265\u03b31 or \u03b2\u2265\u03b21 is satisfied, the vehicle is in the non-stable region; in which \u0394\u03b3 is a difference between the yaw velocity and an estimated yaw velocity; and the estimated yaw velocity is calculated according to a formula of \u03b3 d = \u03b4 r \u22c6 v x / L 1 + K \u22c6 v x 2 ; where \u03b3 d  is the estimated yaw velocity, \u03b4 f  is a turning angle of front wheels of the vehicle and deduced from the steering wheel angle; v x  is a transverse speed of the vehicle and deduced from the wheel speed; L is a distance between a front shaft and a rear shaft of the vehicle; K is a stability factor, and K = m L 2 \ue89e ( l f k r - l r k f ) ; where m is the mass of the vehicle; l f  and l r  are distances from the front shaft and the rear shaft of the vehicle to the mass center of the vehicle respectively; k f  and k r  are cornering stiffness of the front shaft and the rear shaft of the vehicle respectively and deduced from the tire pressure; \u03b2 is a sideslip angle and deduced from the wheel speed; \u03b31 is a threshold of the yaw velocity difference, and \u03b21 is a threshold of the sideslip angle.
