混合动力电动汽车的设计和仿真研究

摘要

以大众POLO原型车为基础，对其动力系统关键总成进行了重新设计，确定了其参数并与之与匹配，在MATLAB／Simulink环境下完成了混合动力电动汽车整车建模，并通过在 CYC＿UDDS和 CYC＿ECE＿EUDC循环工况下进行整车的性能仿真模拟，验证了模型的正确性。结果表明，设计车辆动力总成性能参数匹配合理。%In this study,we selected the VW POLO prototype vehicle,and redesigned the key assembly of its power system and carried out the matching analysis of the parameters.A model of the hybrid electric vehicle was built using MATLAB/Simulink software package,and the simulation performance was tested under the conditions of CYC_UDDS and CYC_ECE_EUDC driving cycles.The results showed that the selection of powertrain parame-ters was sound.
