The invention relates to the technical field of vehicle suspension control, in particular to a vehicle suspension vehicle body leveling control method and a vehicle controller. The vehicle body levelness can be efficiently adjusted in real time based on the road working condition, the method is efficient in operation and high in control accuracy, and the influence of ramps, protrusions and pits on the road surface on vehicle body posture leveling is effectively avoided; according to the method, the adjusting capacity of each wheel suspension is fully considered and utilized, and the height of each wheel suspension from each suspension to the leveling state can be accurately calculated within the adjusting capacity range of the vehicle suspension; if the vehicle body exceeds the suspension adjusting capacity range, the travel adjusting capacity of each wheel suspension can be utilized to the maximum extent, so that the vehicle body is close to the horizontal plane to the maximum extent; the final height of the suspension is all within the travel range of the suspension, overtravel work of the suspension is avoided, damage to the suspension is avoided, and the service life of the suspension is prolonged.

    本发明涉及车辆悬架控制技术领域,具体涉及一种车辆悬架车身调水平控制方法及车辆控制器。本发明能够基于路工况实时高效的调整车身水平性,方法运算高效、控制精确度高,有效避免了路面存在坡道、凸起、凹坑对车身姿态调平的影响;本发明充分考虑利用了各轮悬架的调整能力,在车辆悬架调整能力范围内,则可准确计算处各悬架至调平状态的各轮悬架高度;若超出悬架调整能力范围,则可最大程度的利用各车轮悬架的行程调整能力,使车身最大程度的靠近水平面;本发明最终悬架的高度全部在悬架的行程范围内,避免了悬架超行程工作,避免了悬架的损坏,提高了悬架的工作寿命。
