Abstract

Abstract: Aiming at a single-motor hybrid electric vehicles, four standard cycles including congestion, city, suburb, highway which were chosen as the working condition of the power system design, and the parameter of the engine, motor, battery and transmission were matched. On the Matlab/Simulink platform, the mode was built to simulate dynamic and economic performance. Simulation results indicate that the fuel consumption per hundred kilometers have increased respectively by 17.5%, 32.0%, 14.5% comparing with conventional car under NEDC, UDDS, HWFET.

Key words: vehicle engineering, hybrid electric vehicle(HEV), standard cycle, dynamic and economic performance

摘要： 针对一款单电机混合动力汽车，选择拥堵、市区、市郊、高速等4种标准循环作为动力系统设计的特征工况，匹配了发动机、电机、电池以及变速器的参数;在MATLAB/Simulink仿真平台下建立模型进行了动力性能和经济性能仿真。结果表明:所设计的混合动力汽车能满足动力性指标要求，在NEDC，UDDS，HWFET循环工况下的百公里油耗比传统车分别降低了17.5%，32.0%， 14.5%。
