The invention relates to the technical field of vehicle driving safety control, and discloses an active roll vehicle anti-rollover control method. According to the adopted technical measures, in the vehicle driving process, the instantaneous speed, the yaw velocity and the yaw acceleration of a vehicle are dynamically read, the roll angle beta required for eliminating the curve driving centrifugalforce is calculated, the execution curve driving roll angle beta is calculated, and the vehicle rolls to guarantee the driving stability; in the high-speed running process of the vehicle, rear wheelsideslip, vehicle drifting and sudden change of yaw angular acceleration are caused by reduction of road adhesion, and by predicting the change rule of the yaw angular speed, the non-rollover safety roll angle beta n, the execution safety roll angle beta n and the vehicle roll-over elimination roll-over force of the vehicle are calculated, vehicle roll-over is prevented, and the high-speed runningsafety of the vehicle is guaranteed.
本发明涉及车辆行驶安全性控制技术领域,公开了一种主动侧倾车辆防侧翻控制方法,所采用的技术措施为:车辆行驶过程中,动态读取车辆瞬时速度、横摆角速度、横摆角加速度,计算消除弯道行驶离心力所需侧倾角β,执行弯道行驶侧倾角β,车辆侧倾保障行驶稳定性;车辆高速行驶过程中,路面附着力下降引起后轮侧滑、造成车辆甩尾,导致横摆角加速度突变,通过预测横摆角速度的变化规律,计算车辆不侧翻安全侧倾角βn,执行安全侧倾角βn,车辆侧倾消除侧翻力、防止车辆侧翻,保障车辆高速行驶安全性。
