摘要
提出一种插电式四轮驱动混合动力汽车的结构,并对该结构进行详细分析。利用Cruise软件搭建该插电式四轮驱动混合动力汽车的整车仿真模型,利用Matlab/Simulink软件搭建整车控制策略。对该插电式四轮驱动混合动力汽车的主减速器传动比和动力电池SOC的上限值和下限值进行优化分析,得到最佳的主减速器传动比和SOC的上限值和下限值。根据优化结果可以显著改善该车的动力性和经济性。
The structure of a four-wheel-drive plug-in hybrid vehicle was proposed and analyzed in de-tail. The simulation model of the vehicle was constructed by Cruise software, the control strategy of thevehicle was constructed by Matlab / Simulink software. The gear ratio of the final drive and the upperlimit and lower limit of the battery＇s SOC were optimized to obtain optimal gear ratio of the final driveand the upper limit and the lower limit of the battery＇s SOC, which can significantly improve the vehi-cle＇s dynamical performance and fuel economy.
