摘　　要：介绍了串联型增程式电动汽车的基本结构和工作模式,给出了选配电动汽车发动机和评价整车燃油经济性的方法.利用Cruise/Simulink联合仿真平台对整车进行建模与仿真,引入基于规则的发动机定点和最优曲线能量控制策略.典型工况下的仿真结果表明:发动机最优点能量控制策略能够使发动机和发电机工作在效率最高点,其燃油经济性优于最优曲线能量控制策略;在增程模式下,当采用发动机最优曲线能量控制策略时,增程式电动汽车获得了较好的燃油经济性和控制效果,且该策略有利于发动机的最小化.The basic configuration and operation modes of the series extended-range electric vehicle were analyzed and a novel method for engine choice and fuel economy evaluation was proposed. A co-simulation platform was set up using Cruise and Matlab/Simulink to evaluate the rule based engine on off and optimal operation line control strategies. The simulation results with typical driving cycles illustrate that, first, the engine on off control strategy makes the engine and generator operate at their best efficiency points, and its fuel economy is better than that of the optimal operation line control strategy; secondly, when the optimal operation line control strategy is adopted in the extended-range mode, the engine downsizing will be benefi cial and the extended range electric vehicte（E-REV） will achieve a better fuel economy and control effect.
