双模混合动力整车仿真模型建立及分析

Establishment and Analysis of a Simulation Model for the Two-Mode Hybrid Electric Vehicle

以通用、戴姆勒-克莱斯勒和宝马联合开发的双模混合动力系统(Two Mode Hybrid,TMH)为研究对象,在Matlab/Simulink环境下,以ADVISOR中自带的丰田第一代Prius车型为基础,进行二次开发,完成车速计算模块、动力系统关键部件模型的搭建,建立双模混合动力汽车仿真分析平台.进而提出一种电力辅助式控制策略和模糊逻辑控制策略相结合的控制方法.选取美国城市道路循环工况和郊区道路循环工况,对双模混合动力系统和丰田THS系统作对比仿真,发现双模混合动力系统有着良好的燃油经济性和排放性.

The two-mode hybrid（TMH） system jointly developed by General Motors,Daimler-Chrysler and BMW companies was token as study object in this paper.By using Matlab/Simulink,secondary development was made based on the model of the first-generation Prius,which can be found in the simulation software ADVISOR.The model of vehicle speed calculation,as well as the model of the key component of the power system was built.Through this way,a simulation platform for the two-mode hybrid electric vehicle was created.An advanced control strategy,combined with electric assistant control and fuzzy logic control,was proposed.At last,the urban dynamometer driving schedule（UDDS） and city-suburban heavy vehicle route（CSHVR） were chosen as the testing driving cycle.With the comparison of the simulation results of the Toyota Prius,it is easily to find that two-mode hybrid vehicle has very good fuel economy while maintaining reasonable emission characters.
