Abstract


Computer simulation as a practical technology for electric vehicles in the R \u0026 D process, before prototype testing of the design to conduct a comprehensive assessment, quickly and accurately predict vehicle performance, theory, technology, and design of electric vehicles greatly improve the capacity for foresight, effective shorten development cycles and reduce development costs, and provide a strong technical support for the rapid development of electric vehicles. In this paper, the current domestic and international electric vehicle simulation software features a single simulation accuracy is not high, the second development is difficult and can not meet the needs of the current situation in the research and development of electric vehicles in China, the simulation based on the study of electric vehicle simulation technology, developed a set of user-friendly, highly interactive, scalable migration pure electric vehicle simulation platform, to meet the demand for a pure electric vehicle research and development of simulation. Specifically, the main work of the thesis are: (1) draw on a variety of mature model vehicle parts, vehicle parts to the electric vehicle simulation software ADVISOR2002 model library based extract the right parts, in accordance with the design of the top-level structure of pure electric vehicles model, the completion of the simulation platform component model library design. (2) data exist for the pure electric vehicle simulation data volume, complex data types, data organization forms in accordance with the structure in the form of pure electric vehicle using the tree hierarchy to organize the simulation data and XML file simulation parameters in the form of storage, and data read and write operations. (3) The combined use of both VC and Matlab / Simulink development tools, development of the VC client program software interface design and business process, pure electric vehicle modeling and simulation by Matlab / Simulink, mixed programming, complete the development of an integrated simulation platform. (4) for single battery energy source of pure electric vehicles can not meet the performance disadvantage of commercial operation, designed battery - ultracapacitor dual energy source system and its fuzzy optimization of energy management strategies and pure electric vehicles for dual energy source simulation platform transplantation. (5) in selected models and road cycle conditions, the simulation results of the simulation platform comparative study on the basis of pure electric vehicle using fuzzy optimization control strategy of dual energy source vehicle simulation. The results show that the simulation platform high credibility to meet the requirements of pure electric vehicle simulation and fuzzy optimization control strategy of dual-energy source of pure electric vehicle power performance and economic performance has greatly improved.
