The invention discloses a vehicle traveling leveling method based on suspension active control, which belongs to the technical field of suspension control, and comprises the following steps of: constructing a dynamic reference and a reference error by using physical quantities such as a dynamic travel, a pitch angle and a roll angle of a suspension which can be directly measured only by using a vehicle-mounted sensor; the dynamic reference can reflect the general trend of the overall fluctuation of the road surface, and ensures that the reference error needing to be adjusted does not exceed the effective stroke of the actuator. When the vehicle is static on the horizontal road surface, the dynamic reference returns to the zero position; the practical problem that an existing method depends on and is limited to the vertical height of a vehicle body is solved. According to the method, the design thought of the driving leveling system is clearer, the control method is easier to implement, the technical bottleneck of high dependence on the plumb of the vehicle body is broken through, and a new thought of vehicle driving leveling is developed.
本发明公开了一种基于悬架主动控制的车辆行车调平方法,属于悬架控制技术领域,包括只利用车载传感器可以直接测量的悬架动态行程及俯仰角和侧倾角等物理量,构建动态基准和基准误差。动态基准能够反映出路面整体起伏的大趋势,并确保需要调节的基准误差,不超出作动器的有效行程。当车辆静止于水平路面时,动态基准回归零位;解决现有方法对车身铅垂高依赖和限制的实际问题。本发明可使行车调平系统设计思路更加清晰,控制方法实现更加简单,并且突破了对车身铅垂高依赖的技术瓶颈,开拓了车辆行车调平新思路。
