摘要
以某插电式串联混合动力轿车为例,在整车性能指标和系统结构确定的基础上,对电驱动系统、储能系统和辅助动力单元进行选型和优化匹配,确定了发动机的最优工作点。对所建的整车仿真模型,分别采用国家标准规定的UDC和NEDC循环工况、轻型车循环工况和等速行驶工况,进行整车动力性、经济性的仿真验证。结果表明,在3种工况下,所确定的动力系统方案都能很好地满足整车动力性和经济性的要求。
Taking a plug-in series hybrid electric car as example,based on definite vehicle performance and system architecture,the type selection and optimization matching for its electric drive system,energy storage system and auxiliary power unit are conducted and the optimal working points of engine are determined.By adopting UDC and NEDC driving cycle defined in national standard,driving cycle for light vehicles and constant speed driving cycle respectively,verification simulations on vehicle performance and fuel economy are carried out based on the simulation model built.The results show that with all three driving cycles,the power system scheme determined can well meet the requirements of vehicle performance and fuel economy.
