The embodiment of the invention discloses a vehicle mass center position determination method and device, equipment and a storage medium, and relates to a vehicle rollover prevention equipment technology, and the method comprises the steps: obtaining the current relative position variation between a vehicle body and a wheel when a triggering condition of a rollover prevention stability control system is met; calculating a lateral load transfer rate LTR according to the current relative position variation; and introducing the LTR, the lateral acceleration of the vehicle and the roll angle of the vehicle body into a roll kinetic equation, and calculating the vertical coordinate value of the mass center of the vehicle. According to the method of the invention, the control effect of an RSC (Roll Stabilization Control) strategy can be effectively improved, so that the rollover stability of the vehicle and the effectiveness of rollover prevention equipment of the vehicle are ensured.

    本发明实施例公开了一种车辆质心位置确定方法、装置、设备和存储介质,涉及车辆防侧翻装备技术,方法包括:在满足防侧翻稳定控制系统触发条件时,获取车身与车轮之间的当前相对位置变化量;根据所述当前相对位置变化量计算横向载荷转移率LTR;将所述LTR、车辆侧向加速度和车身侧倾角带入到侧倾动力学方程中,计算车辆质心的垂向坐标值。本发明实施例能够有效提升RSC(Roll Stability Control,防侧翻稳定控制系统)策略的控制效果,从而保证车辆侧翻稳定性,以及车辆防侧翻装备的有效性。
