Hybrid vehicle modeling and virtual simulation

Abstract With the growing shortage of energy supply of oil，motor fuel increasingly serious environmental pollution, hybrid vehicles is the new energy vehicles to electric power as a driving force, by virtue of this new energy saving and environmental protection capacity in the international market,it has become noticeable vantage point。 Since the 1980s, many developed countries, international investment funds to research and developing electric vehicles, but due to the electric car battery problems that many environmental factors turning type of development with hybrid cars, electric cars have become as a key project。

Energysaving technology has become the new century's global theme,the growing shortage of energy requirements for the emergence of new power technology。 The principle and application status automotive hybrid technology is the main research to body the moment, analysis of the core technology of automotive hybrid and integrated to understand the key technical problems in hybrid vehicles that need to be addressed，it is the current challenges to face and opportunity。 This describes the various operating state of the hybrid vehicle, for modeling and simulation of energy conversion, the use of matlab software finish a simulation, with simulated images to represent cars in various states of operation。 Then use the simulink simulation, and the simulation results are analyzed in different operating environments to verify the accuracy, stability and effectiveness of the system。
