摘要
为研究纯电动汽车匹配自动变速器对整车经济性的影响,利用AVL-CRUISE软件建立前向仿真模型,以整车原地起步加速时间作为动力性约束,针对6种典型工况分别开展匹配单速比变速器和自动变速器对整车经济性影响的分析。结果表明,较单速比变速器,匹配自动变速器的纯电动汽车其电机可更多地工作在高效率区域,经济性能约提升4%。
To study the economy of electric vehicle matching automatic transmission, a forward simulation model based on the AVL-CRUISE software is built. Taking the vehicle standing start acceleration time as a bound, the economy effect analysis of electric vehicle matching single ratio transmission and automatic transmission has been developed with 6 typical cycles. The simulation result shows, compared with single ratio transmission, the e-motor of electric vehicle matching automatic transmission has more probability working on high efficiency area, and the economy can be promoted by 4%.
