The Parameters Matching And Performance Simulation Of Series Hybrid Electric Vehicle Powertrain

The auto industry as a significant role in promoting the economic development ofcountries,but also causes gurat threat to the worled’s energy of energy-saving and newenergy vehicles to the National Strategic.In view of the low battery energy density of pureelectric vehicle,the short driving range of one charge,hybrid electeric vehicles have becomethe mainstream of the world countries main direction and commercialization.due to its hightransport effciency,low transportation costs and other characteristics.Heavy commercialvehicles have become the darling of the road transportation.With the rise of theinternational oil prices,as well as the implementation of the state IV emission standards. Thehybrid heavy commercial vehicles are gainning more importance.Based on santana2000to design a prototype, by redesigning the power drive systemwill become a series hybrid electric vehicle, the design of the application of the hybridtechnology has made the thorough analysis and research, the main work of the series hybridelectric vehicle structure layout, power system main components selection, parameterdesign, matching, main component modeling, system performance simulation and some ofthe parameters of the optimization are analyzed and discussed. The specific researchcontents and steps are as follows:The structure scheme and the determination of controlstrategy. Comprehensive analysis and comparison of hybrid structure of vario us types andvarious coupling device structure features, advantages and disadvantages, and conditions ofuse, on the basis of determining this topic selected the series hybrid electric drive systemand control strategy of sorrowful solution type, and the specific scheme is introduced.Thedesign of the two main components selection and parameter matching. Research analyzesthe series hybrid electric vehicle drive system main components of operating characteristics,combined with hybrid power performance index to the main drive of the hybrid componentsselection and parameter design, finally it is concluded that the vehicle power system anddrive train parameters. In the ADVISOR based on MATLAB/SIMULINK environmentmodel and control strategy of main components of powertrain, and ADVISOR of thevehicle model is established. Analysis of the simulation calculation results. ADVISOR environment of vehicle performance and fuel economy index as the research target, theinput parameters and simulation analysis. Optimization of the parameters. In ADVISOR forthe transmission and control strategy of parameter optimization design, analysis andcomparison of different parameters with the simulation results, the best design parameters toget power performance and fuel economy.
