摘　　要：为了减少车辆控制系统的研发成本,近年来虚拟仿真技术在车辆控制系统的开发研究中得到了广泛的应用.以某皮卡车为研究对象,运用ADAMS/view软件建立了包括前后悬架、轮胎、车身、转向系和人椅系统等在内的整车多刚体动力学模型,并对建模中的若干关键问题进行了详细的论述.利用ADAMS/view中的控制工具箱设计了基于PID控制策略的主动悬架控制系统,对其进行闭环系统仿真,通过不断修正控制参数直至得到满意的控制效果.将采用主动悬架系统得到的仿真结果与采用被动悬架系统得到的仿真结果进行了性能对比,结果表明,主动悬架系统有效地改善了车辆的行驶性能.An ASS combined simulation model is presented based on the co-simulation technology. Based on ADAMS/view software package , a multi-body dynamic model of a pickup vehicle is established, in which suspensions, tires, vehicle body, steering system and person-chair system are considered. Some key problems in establishing model are discussed. Using control toolkit, a PID control system is designed for active suspension system. Simulation has been performed repeatedly until satisfactory control parameters are achieved. Compared with a conventional passive system, simulation results show that the proposed active suspension has considerably improved the running performance of the vehicle.
