摘　　要：以某小型增程式电动汽车为原型，提出了一种基于动力分布设计的新构型方案。在此基础上进行了参数匹配与设备选型，并提出了适合这一构型方案的控制策略。结合匹配结果和试验数据，使用AMESim和Matlab／Simulink联合仿真平台搭建了整车数学模型，并针对动力性、纯电动续驶里程、再生制动效率及增程模式能耗等方面进行了仿真分析。结果表明：基于动力分布设计的增程式电动汽车，在不降低动力性能的前提下，拥有较小的整备质量和较高的再生制动效率，可提高纯电动续驶里程30％以上、降低增程模式能耗3％～6％，具有节能潜力。This paper presents a new powertrain configuration based on power distribution design of an extended-range electric vehicle. First,the parameters match and equipment selection were studied and a control strategy was proposed. Then,combined with the matching results and test data,the mathematical model of the vehicle was built with AMESim and Matlab-Simulink software platform. The model was analyzed aimed at the dynamic performance,EV-mode mileage,regenerative braking efficiency and extended-range model fuel consumption. Results show that the extended-range electric vehicle with the power distribution design has a smaller curb weight and higher regenerative braking efficiency without compromising the dynamic performance. This configuration could improve the EV-mode mileage for more than 30%, reduce the extended-range model fuel consumption for 3% ~ 6%,and has ideal energy-saving potential.
