The invention provides a vehicle suspension control method, a vehicle control unit and a vehicle, and the method comprises the steps: obtaining the vehicle body posture information of the vehicle, the driving speed in the driving direction, and the road information calculation data of the current driving road of the vehicle in real time; road information is determined according to the obtained road information calculation data and the vehicle body posture information, and the suspension target height difference of suspensions on the left side and the right side of the vehicle is determined according to the running speed of the vehicle in the running direction, the road information and the vehicle attribute information influencing the roll angle of the vehicle; generating an adjusting instruction for adjusting the heights of the suspensions according to the target height difference of the suspensions, and adjusting the height difference of the suspensions on the left side and the right side of the vehicle to be within the target adjusting range according to the adjusting instruction. According to the scheme, by controlling the heights of the suspensions on the left side and the right side of the vehicle, the vehicle can generate the component force which is counteracted with the centrifugal force of the vehicle and has the gravity in the horizontal direction, the calculation process is simple, and the influence caused by vehicle roll on passengers is reduced.

    本发明提供一种车辆悬架的控制方法、整车控制器及车辆,其中,方法包括:实时获取车辆的车身姿态信息、行进方向上的行驶速度、以及车辆当前行驶道路的道路信息计算数据;根据获取到的道路信息计算数据和车身姿态信息确定道路信息,并根据车辆在其行进方向上的行驶速度、道路信息、以及影响车辆侧倾角的车辆属性信息确定车辆左右两侧悬架的悬架目标高度差;根据悬架目标高度差生成调节悬架高度的调节指令,并根据调节指令调节车辆的左右两侧悬架的高度差处于目标调节范围内。本方案通过控制车辆的左右两侧悬架的高度,使车辆能够产生与车辆的离心力相抵消的、重力在水平方向上的分力,计算过程简单,也减少了乘员受到的车辆侧倾带来的影响。
