Based On The Performance Of The CVT Hybrid Cars

Now the car has become one of the world’s most commonly used traffic tools people, with the automobile usage gradually increase, the car brought about environmental problems have become more and more large. Now the environment facing the biggest harm is the exhaust emissions contribute to global warming, and fuel combustion lead to global oil reserves face dry.Therefore, the use of new energy vehicles to replace the traditional energy automobile has become an important means of automotive production. With the development of hybrid vehicles is most rapid, and the technology is relatively mature.This paper takes a certain type of CVT hybrid electric vehicle as the research object, aiming at the control strategy and dynamic performance simulation analysis. The main contents of the thesis can be divided into the following several aspects:1. Introduces the types of hybrid cars and development prospect. At the same time, for the simulation of hybrid electric vehicle technology current development at home and abroad and hybrid electric vehicle control strategy are outlined.2. Taking a certain type of CVT hybrid electric vehicle as the research object. Collection the main parameters of transmission about CVT hybrid electric vehicle, the main parameters of the battery and the main parameters of the motor. Modeling analysis of the whole vehicle system and control strategy.3. Through the matlab/simulink® implementation CVT hybrid electric vehicle main performance and control strategy simulation and analyses the result.Overall, in this paper for the research of CVT hybrid electric vehicle with system, not only for the theory of hybrid electric vehicle are discussed, but also on the CVT hybrid car follow-up development laid a good foundation.
