The invention relates to the technical field of vehicle control, in particular to a vehicle stability control method and system, a domain controller and a medium. According to the method, when the current vehicle speed of a vehicle at the current moment is not smaller than a reference vehicle speed, according to the real-time yaw velocity, the steering angle of a steering wheel and the current vehicle speed of the vehicle at the current moment; obtaining the side slip angle of the vehicle and the steady-state yaw velocity of the vehicle; according to the angular velocity difference between the steady-state yaw velocity and the real-time yaw velocity, in combination with the side slip angle, a compensation value needed for stabilizing the vehicle is calculated; the vehicle is controlled to run stably according to the compensation value, the accuracy of obtaining the compensation value is improved, and the stability performance of the vehicle during steering is enhanced.
本发明涉及车辆控制技术领域,尤其涉及一种车辆稳定控制方法、系统、域控制器及介质,该方法当前时刻下车辆的当前车速不小于参考车速时,则根据当前时刻下车辆的实时横摆角速度、转向盘转角和当前车速,得到车辆的质心侧偏角和车辆的稳态横摆角速度;根据稳态横摆角速度和实时横摆角速度之间的角速度差异,结合质心侧偏角,计算得到稳定车辆所需的补偿值;根据补偿值控制车辆稳定行驶,提高了获取补偿值的准确性,增强了车辆转向时的稳定性能。
