摘　　要：以燃油消耗最小为目标,在Matlab/Simulink中搭建一种混联式混合动力汽车的动力系统模型,基于逻辑门限值的能量管理策略分别在城市和市郊两种道路工况下进行仿真。仿真结果表明,整车需求转矩可以进行有效分配,维持了电池荷电状态的平衡,城市道路工况百公里油耗为4.8 L,市郊道路工况百公里油耗为1.596 L;与传统的燃油车进行相比,城市道路工况下百公里油耗降低率达到了37.4%,高速道路工况下达到了71%。To acquire the minimum fuel consumption,a model of parallel-series hybrid vehicle in Matlab/Simulink was developed using the energy management strategy on the logic threshold,and simulations in urban circulation and suburban circulation conducted respectively.The results show that the vehicle engine torque can be effectively assigned that SOC keeps the balance at 4.8 L consumed per 100 kilometers on urban roads and 1.596 L on suburban roads.Compared with the traditional fuel consuming vehicle,the new model is much more fuel economic,whose fuel consumption per 100 kilometers is 37.4%less on urban roads and 71%less on expressways
