摘　　要：根据所采用发动机的万有特性曲线特征,为发动机制订一条转矩曲线下限,在任何情况下都限定发动机运行于转矩曲线下限之上的低油耗区域。基于Matlab/Simulink建立汽车后向仿真模型。在市区运行工况下运行仿真发现整个行驶期间发动机运行在效率较高的区域,百公里油耗仅为4.008L。最后又分别在市郊行驶工况与综合行驶工况中进行了仿真,百公里油耗量分别为4.518 3L、4.229 9L。验证了所制定能量管理策略在市郊工况与综合工况中同样表现出了较高的燃油经性。对比市区油耗、市郊油耗、综合油耗后发现,混合动力汽车的节油性在市区工况中体现的更加明显。The lowest engine torque curve was built according to engine universal characteristics curve,and the engine was restricted to work in the low fuel district above the lowest torque curve in any case.The vehicle backward simulation model was built based on Matlab/Simulink.It was found that engine worked in the high efficient district in the city driving condition all the time and its fuel consumption per hundred kilometers was just 4.008 L.In the end,it was also simulated in the suburb driving condition and compositive driving condition,and the fuel consumption per hundred kilometers were4.5183 Land 4.2299 Lrespectively.The energy management strategy was also testified high fuel economy in the suburb driving condition and compositive driving condition.Comparing the fuel consumption of city condition,suburb condition and compositive condition,the high fuel economy of hybrid electric vehicle was more evident in the city condition.
