The invention relates to the technical field of automobiles, in particular to a vehicle stability control method and system, a vehicle and a storage medium. The vehicle stability control method includes the steps of: estimating a side slip angle and a yaw velocity of a vehicle according to a signal measured by a whole vehicle sensor to obtain a side slip angle estimated value and a yaw velocity estimated value of the vehicle, and identifying a side slip angle expected value beta d and a yaw velocity expected value gamma d expected by a driver at the current moment according to a longitudinal vehicle speed vx and a front wheel rotation angle delta; according to the difference value between the estimated value of the side slip angle and the expected value beta d of the side slip angle and the difference value between the estimated value of the yaw velocity and the expected value gamma d of the yaw velocity, obtaining an additional yaw moment Mz needed by vehicle stability control; and distributing the additional yawing moment Mz to obtain the wheel cylinder brake pressure required for controlling each wheel by the stability of the whole vehicle. The stability of vehicle control can be improved.

    本发明涉及汽车技术领域,尤其涉及一种车辆稳定性控制方法、系统、车辆和存储介质,车辆稳定性控制方法包括如下步骤:根据整车传感器测量得到的信号对车辆的质心侧偏角和横摆角速度进行估计得到车辆的质心侧偏角估计值和横摆角速度估计值根据纵向车速vx和前轮转角δ辨识当前时刻驾驶员期望的质心侧偏角期望值βd和横摆角速度期望值γd;根据所述质心侧偏角估计值与所述质心侧偏角期望值βd的差值,以及所述横摆角速度估计值与所述横摆角速度期望值γd的差值得到车辆稳定性控制所需的附加横摆力矩Mz;对附加横摆力矩Mz进行分配,得到整车稳定性控制各个车轮所需的轮缸制动压力。本发明能够提升车辆控制的稳定性。
