Study On Parameters Design And Control Strategy For Powertrain System Of Extented-range Electric Vehicle

As the rapid development of automobile industry and growth of vehicle population,resources and environment are facing tough challenges in our country. Electric vehicles (EVs)seem to be an important way to protect our energy security and transform economy to aLow-Carbon Economy. However, the challenges that remain for modern EVs are limitationsin driving distance, system costs, short battery lifespan and limited customer benefits. As anElectric Vehicle which can extend range, Extended-Range Electric Vehicles are the ElectricVehicle product which is most likely to be industrialization and enter the common family inthis phase. So Extended-Range Electric Vehicles have been the focus research anddevelopment products at the present time.The paper search and read the available literatures to analyses the present technologyLevel of Extended-Range Electric Vehicles. Discusses the definition and the status ofdevelopment research of Extended-Range Electric Vehicles. According to performance targetsand structure characteristics of the vehicle, the key components of the powertrain are selectedand parameter matching are carried out. The operating mode of the Extended-Range ElectricVehicles is analyzed. According to its mode of operation, the control strategies of generalseries hybrid electric vehicles and Extended-Range Electric Vehicles were studied todetermine the control strategy in line with Extended-Range Electric Vehicles run mode.Use oftheoretical analysis and mathematical modeling methods to built vehicle simulation modeland control strategy model in ADVISOR software. The matching results of parameters andpowertrain control strategies were developed simulation. Under the premise of improving thefuel economy of the control strategy parameters were optimized and the optimal controlstrategy parameter are determined, the optimized results has improved the fuel economy andhas practical value.
