基于循环工况的单电机混合动力系统参数匹配

Parameter Matching of Single-Motor Hybrid Electric Vehicle Based on Driving Cycles

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%。

Aiming at a single-motor hybrid electric vehicles, four standard cycles including congestion, city, suburb, high- way 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.
