插电式混合动力汽车动力系统参数研究

摘要

How to design transmission parameter in order to realize the optimal matching between engine and transmission system was very important in the primary design of a car. This paper studied a Plug - in Hybrid Electric Vehicle's transmission system, and integrated the automobile's power index with economy performance to put forward a new study method which combines the project with simulation. The new method was used to choose the main compoment of the transmission system and ascertained the parameters of the engine, the ISG motor, the main electromotor, the retarter and the battery. At last the Matlab/simulink and ADVISOR were used for simulation. The results showed that the parameters were suited for the design. Also the power performance and fuel consumption performed well. It gives a good matting for the future excogitation.%在研发一款新车的初期,如何设计动力系参数以达到与汽车发动机的合理匹配足设计中一个关键的问题.针对一种新型插电式混合动力汽车(Plug-in HEV,PHEV)的动力系统进行分析研究,综合汽车动力性评价指标和经济件评价指标为目标,提出了用工程分析与仿真校验相结合的方法对传动系统的主要部件进行了选型,确定了发动机、ISG电机、后驱动电机、主减速器、电池的参数,最后利用Matlabsimulink和ADVISOR软件对整车性能进行仿真计算,结果表明所确定的动力系统的参数基本达到了汽车的动力件和经济性的设计要求,为后期的研发工作起到了很好的铺垫作用.
