The invention relates to the technical field of vehicle control, and provides an anti-rollover method and device and a vehicle. The method comprises the steps that center-of-gravity shift information of the vehicle is obtained, and the center-of-gravity shift information is used for determining the center-of-gravity shift direction and the corresponding center-of-gravity offset; and if the center-of-gravity offset in the current time period is smaller than a set threshold value and the center-of-gravity offset has an increasing change trend in the corresponding center-of-gravity offset direction, determining a target action for limiting the vehicle in the center-of-gravity offset direction corresponding to the center-of-gravity offset. Thus, the problem that tipping early warning is not timely is solved, if the gravity center offset in the current time period is smaller than the set threshold value and the gravity center offset has an increasing change trend in the corresponding gravity center offset direction, it is indicated that the vehicle has a tipping trend, and the tipping early warning is not timely. The target action of the vehicle in the center-of-gravity shift direction corresponding to the center-of-gravity offset can be actively and adaptively limited in advance, the center-of-gravity offset is prevented from continuing to increase in the center-of-gravity shift direction, and effective anti-rollover early warning of the vehicle is achieved.
本发明涉及车辆控制技术领域,提供一种防倾翻方法、装置及车辆,其中方法包括:获取车辆的重心偏移信息,重心偏移信息用于确定重心偏移方向及对应的重心偏移量;若当前时间段内重心偏移量小于设定阈值且重心偏移量在对应的重心偏移方向上呈增大的变化趋势,确定限制车辆在重心偏移量对应的重心偏移方向的目标动作。如此,解决了倾翻预警不及时的问题,若当前时间段内重心偏移量小于设定阈值且重心偏移量在对应的重心偏移方向上呈增大的变化趋势,表明车辆存在发生倾翻的趋势,可以主动提前自适应限制车辆在重心偏移量对应的重心偏移方向的目标动作,阻止重心偏移量在重心偏移方向上继续增大,实现了车辆的防倾翻有效预警。
