The invention provides a vehicle stability control method and system, and the method comprises the steps: obtaining the lateral offset of a mass center when the vehicle stability control system is inan activated state; when the absolute value of the centroid transverse offset is larger than a first threshold value, adjusting the damping force of shock absorbers on the left side and the right sideof the vehicle according to the centroid transverse offset and the difference value between the current left measured wheel pressure and the current right measured wheel pressure; when the absolute value of the centroid transverse offset is smaller than or equal to a first threshold value, obtaining a steering wheel rotating angle; and when the absolute value of the steering wheel rotation angleis larger than a preset rotation angle, adjusting the damping force of shock absorbers on the left side and the right side of the vehicle according to the steering wheel rotation angle, the vehicle speed and the difference value between the current left-side wheel pressure and the current right-side wheel pressure. By changing the damping force of the shock absorbers at the wheels, the steering comfort of the vehicle is improved, stable and comfortable steering driving of the vehicle is guaranteed, and the vehicle is effectively prevented from rolling over.

    本发明提供了一种车辆稳定控制方法及系统,车辆稳定控制方法包括:在车辆稳定控制系统处于激活状态时,获取质心横向偏移量;在所述质心横向偏移量的绝对值大于第一阈值时,根据所述质心横向偏移位量,以及当前左测车轮压力和右侧车轮压力差值,调整车辆左右两侧避震器的阻尼力;在所述质心横向偏移量的绝对值小于或等于第一阈值时,获取方向盘转角;在所述方向盘转角的绝对值大于预设转角时,根据所述方向盘转角、车速,以及当前左测车轮压力和右侧车轮压力差值,调整车辆左右两侧避震器的阻尼力。本发明通过改变各车轮处避震器的阻尼力,改善了车辆的转向舒适性,保证车辆稳定舒适的转向驾驶,有效的预防车辆发生翻滚。
