摘　　要：串联式液压混合动力车辆能够切断发动机与驱动桥之间的直接联系,是一种适合于中小型城市车辆的混合动力方式。基于AMESim-Stateflow联合仿真的平台,对串联式液压混合动力车辆进行建模,利用基于逻辑门限值的能量控制策略对车辆动力装置进行合理控制,采用1015工况作为模拟分析的循环工况。仿真结果表明,串联式液压混合动力车辆不仅能够满足车辆的动力性与制动性要求,而且有效地提高了车辆的燃油经济性。Series hydraulic hybrid vehicle can cut off the contact between the engine and the drive axle. It is a suitable hybrid mode for small-or medium-sized city vehicles. Based on AMESim-Stateftow co-simulation platform, hydraulic series hybrid vehicle is modeled, using logic threshold energy control strategy and 1015 driving cycle condition. The results show that series hydraulic hybrid vehicle can not only meet the requirements of the braking and dynamic of the vehicle, but also improve the fuel economy of the vehicle.
