| The drive system of Hybrid Electric Vehicle is composited of gas engine and electric engine. Compared of previous vehicle, Hybrid Electric Vehicle can privode the run power, but also can help resove energy scarcity and environment pollution, So it has a bright future.This paper's analysis is based on A Hybrid Elctric Vehicle. I bring forward Intergrity-Vehicle hybrid electirc drive ISG parallel connection distribution method, and I have designed engine, electric engine, dirve batteries and other technology mathing parameters.According to all assemblies' parameters in preliminary scheme, I established mathematic models of all assemblies and intergrity-vehicle, and puted forward energy assignation control strategy aimed at A Hybrid Electirc Vehicle's control objects and main technology targetsI analysized the drive system parameters using MATLAB/SIMULINK emluator, and the results indicates that the power and Economic characters are accordant to Hybrid Electric Vehicle's standards.Up on the Hybrid Electric Vehicle platform, I took the experiments of engine, electric engine assembilies, Hybrid electric system, parallel drive and engine drive. I also took the experiments of vehicle on outside road, in order to check the economic characteristics. The experiments results indicate: The Vehicle'power is up to the mustard and the economic characteristics of vehicle has been improved much more, and also experiments evidences proved the rationality of the Hybrid Electric Vehicle configuration and control system.At the end of the paper, the conclusions of the research and the innovation points are presented, and expectation on further research and development is also put forward.
