The invention relates to an anti-rollover control method and an anti-rollover control system, and the anti-rollover control method comprises the following steps: 1, based on a vehicle signal, obtaining a relation between a tire vertical load Fz of each wheel and a wheel slip rate s; step 2, acquiring the position of the mass center of the vehicle based on the relationship between the tire vertical load Fz of each wheel and the wheel slip rate s and the longitudinal acceleration ax of the vehicle; 3, evaluating the rollover state of the vehicle in real time based on the position of the mass center of the vehicle; and 4, in response to the situation that the rollover state of the vehicle does not meet the first preset condition, the speed and/or the turning radius of the vehicle are/is regulated and controlled in real time. On the basis of not additionally adding hardware, the real-time vehicle mass center position can be obtained, evaluation of the vehicle rollover state and regulation and control of the vehicle are more accurate and timely, in addition, a vehicle signal is measured by an existing sensor, an additional roll angle sensor for measuring the rollover angle does not need to be added, and the hardware cost is saved.

    本公开涉及一种防侧翻控制方法及防侧翻控制系统,防侧翻控制方法包括以下步骤:步骤1,基于车辆信号,获取各个车轮的轮胎垂直载荷Fz与车轮滑移率s的关系;步骤2,基于每个车轮的所述轮胎垂直载荷Fz与车轮滑移率s的关系及车辆纵向加速度ax,获取车辆质心位置;步骤3,基于所述车辆质心位置,实时评估车辆侧翻状态;步骤4,响应于所述车辆侧翻状态不满足第一预设条件,实时调控车辆的车速和/或转弯半径。在无需额外增加硬件的基础上,能够获取实时的车辆质心位置,使车辆侧翻状态的评估以及车辆的调控更加精准和及时,此外,车辆信号由已有的传感器测得,无需增加额外的测量侧翻角度的侧倾角传感器,节约硬件成本。
