According to the vehicle suspension dynamic state observation method and the vehicle suspension dynamic state control method, the state quantity of a suspension system and the road elevation can be estimated only by utilizing a dynamic stroke (or dynamic speed) signal which is easy to measure, and the estimation method does not need sprung or unsprung mass acceleration signals needed by a traditional method, so that the estimation accuracy is improved. The cost of subsequent processing of signals of a sensor and a controller of the control system can be remarkably reduced, the problems caused by integral operation of measurement signals and adoption and processing of high-frequency signals are avoided, engineering implementation is facilitated, and the system reliability is improved; the state estimation method provided by the invention can be used for other control systems of vehicle chassis dynamics, namely, the engineering implementation of the control system needs to depend on the dynamic state of a vehicle suspension to carry out state feedback.
本发明提出了一种车辆悬架动力学状态观测方法及控制方法,仅利用容易测量的动行程(或动速度)信号,可对悬架系统的状态量以及路面高程进行估计,该估计方法不需要传统方法需要的簧上或簧下质量加速度信号,可以显著降低控制系统传感器及控制器信号后续处理的成本,避免了对测量信号的积分运算以及高频信号采用及处理带来的问题,更有利于工程实现及提升系统可靠性;本发明提出的状态估计方法可用于车辆底盘动力学其它的控制系统,即控制系统的工程实现需要依赖车辆悬架动力学状态进行状态反馈的控制方法。
