摘要: 根据某型号纯电动汽车技术指标及设计要求,对动力性能及经济性能相关的主要参数进行了计算及选择,主要涉及电机及电池两部分。基于汽车仿真软件ADVISOR建立纯电动汽车整车模型,设置计算选择所得的相应参数进行仿真验证,分析匹配所得的各项参数是否满足汽车性能要求。在匹配满足要求的基础上建立了动力性能、成本价格及经济性能的多目标函数,通过萤火虫算法对该目标函数进行优化,优化后的参数使得整车的动力性能和经济性性能得到较大的提升,成本价格也有所下降,有效提高了纯电动汽车实用性。

Abstract: According to the design requirements and technical index of pure electric vehicle, the parameters of motor and battery related to power and economic performance are selected based on the computing results. Based on ADVISOR, a vehicle model of pure electric vehicle is established in MATLAB environment with the corresponding parameters validating the simulation results. On this basis, the multi-objective function is established, which includes the power performance, economic performance and cost price. This function is optimized by the firefly algorithm, which makes the dynamic parameters, the dynamic performance and economy performance of pure electric vehicle be improved significantly and the cost prices be declined. The practical performance of pure electric vehicle obtains the enhancement effectively.

Key words: electric vehicle, modeling and simulation, matching optimization, multi-objective function, firefly algorithm
