A Study of Parameter Design of Power and Transmission System for Plug-in Hybrid Electric Vehicle

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.
