摘　　要：应用仿真计算与样机测试相结合的方法研究了装备新型功率分流式无级变速器(PSCVT)的经济型轿车的燃油经济性。对变速器进行了数学建模并将其嵌入到汽车基本性能仿真软件ADVI-SOR的运行环境中,通过二次开发建立了装备该变速器的整车基本性能仿真模型。应用实测的原理样机性能数据,仿真计算了城市循环工况下的整车燃油消耗量,并与原车装备五挡手动变速器时的油耗进行了对比。结果表明:在动力性能保持不变的情况下,整车燃油消耗率得到了较大的降低。最后,对PSCVT的节能机理、控制策略以及与整车匹配的评价准则等进行了分析探讨。In view of the characteristics of （PSCVT）, an economical car fuel economy is the power split continuously variable transmission studied by means of combination of simulation calculation and prototyping test. A PSCVT mathematic model is established and embedded into the simulation software ADVISOR to finish the whole vehicle modeling. Fuel economy comparison between vehicle with PSCVT and traditional mechanical transmission is presented after fuel economy simulation based on the experiment data on the PSCVT prototype under urban dynamometer driving schedule （UDDS）, which indicates that the vehicle fuel consumption is reduced distinctly with the same power performance. The energy-saving scheme and control strategy of PSCVT as well as matching between PSCVT and the whole vehicle is discussed.
