The invention relates to the technical field of vehicles, and discloses a safety control method for a vehicle, a processor, a safety control device and the vehicle. The method comprises the steps that the mass center height of a vehicle in the state that axle load transfer does not occur is obtained; acquiring a first distance between the center of mass and the center line of a front axle and a second distance between the center of mass and the center line of a rear axle when the vehicle does not generate axle load transfer; acquiring a first gradient and an acceleration of the vehicle; according to the second distance, the centroid height and the first gradient, the maximum safe acceleration of the vehicle is determined; according to the first distance, the centroid height and the first gradient, the maximum safety deceleration of the vehicle is determined; and under the condition that the acceleration is larger than the maximum safe acceleration or smaller than the maximum safe deceleration, the vehicle is controlled to enter an active anti-rollover state. The vehicle rollover risk caused by too large vehicle acceleration and too large driving torque is avoided, the vehicle rollover risk caused by too large vehicle deceleration absolute value and too large braking torque is avoided, and the vehicle driving safety is improved.
本发明涉及车辆技术领域,公开了一种用于车辆的安全控制方法、处理器、安全控制装置及车辆。方法包括:获取车辆在未发生轴荷转移状态下的质心高度;获取车辆在未发生轴荷转移状态下质心与前轴中心线的第一距离及质心与后轴中心线的第二距离;获取车辆所处的第一坡度以及加速度;根据第二距离、质心高度以及第一坡度,确定车辆的最大安全加速度;根据第一距离、质心高度以及第一坡度,确定车辆的最大安全减速度;在加速度大于最大安全加速度或者小于最大安全减速度的情况下,控制车辆进入主动防倾翻状态。避免车辆加速度过大、驱动扭矩过大而导致车辆倾翻风险,避免车辆减速度绝对值过大、制动扭矩过大而导致车辆倾翻风险,提高车辆行驶的安全性。
