为降低制造成本,并实现混合动力汽车节省燃油和降低排放,提出了一种采用行星齿轮机构的新型混合动力汽车动力传动系统方案,进行了该系统方案的工作模式分析和参数匹配设计。在MATLAB/Simulink环境下利用整车动力学理论建模与关键零部件（如发动机、ISG电机、电池、变速器以及行星齿轮）数值建模相结合的方法,建立了基于该系统方案和设计参数的混合动力汽车整车性能分析模型,进行了整车动力性能和ECE_EUDC循环工况下的燃油经济性仿真计算分析。结果表明所设计的新型混合动力汽车参数设计合理,具有良好的动力性,燃油消耗较传统车下降36.8%,这为该系统方案的实施提供了理论依据。

In order to reduce production cost and achieve lower fuel and emission,powertrain of a novel hybrid electric vehicle based on planetarygears was proposed.Operation modes and parameters of hybrid power system were analyzed and designed respectively by using a method of dynamic modeling theory combined with numerical model theory of crucial parts such as engine,ISG motor,battery,transmission as well as planetary gears.Performance analysis model of hybrid electric vehicle was built based on system scheme and design parameters,dynamic performance of whole vehicle as well as fuel economy under ECU_EUDC were simulated and analyzed.The simulation results show that the parameters of powertrain are reasonably matched,propulsion performances are excellent,fuel oil consumption is reduced by 36.8% comparing with that of conventional vehicle and it gives theoretical basis to carry out the system schema.
