摘要
外充电式混合动力汽车是电动汽车较好的技术路线,也是当前研究的热点。构建了一辆前轮发动机驱动、后轮电动机驱动的外充电式四驱混合动力汽车模型,进行了电机、电池和发动机参数设计,设计了发动机最优工作曲线能量控制策略和电能消耗型能量控制策略,并用Matlab和AVL Cruise软件对其进行了性能联合仿真。结果表明,所构建汽车模型可行,匹配动力系统参数设计达到预期目标,电能消耗型能量控制策略更有利于提高经济性。动力系统结构和能量控制策略易于产业化,可为样车开发提供借鉴。
Development of plug-in hybrid electric vehicle （HEV） is a good technical route and research focus for electric vehicles. A plug-in 4WD HEV was constructed which matched a front-wheel combustion engine driving system and a rear-wheel motor driving system. The motor parameters, battery parameters and engine parameters were designed for the HEV. The energy control strategy of the optimal engine work curve and of electric energy consumption were designed. Some simulations by using software Matlab and Cruise were conducted applying the two strategies. The results show that the structure of the proposed vehicle model is feasible, its design meets the target and the energy control strategy of electric energy consumption is more helpful to improve the economic perltwmance. The powertrain structure and energy control strategy are easy to be industrialized, which can provide a reference for prototype development.
