摘要： 提出一种基于金属带式无级变速传动(Continuously variable transmission, CVT)与行星齿轮机构的新型功率分流式混合动力汽车动力传动系统方案，分析该系统所具有的各种工作模式，并针对长安某车型参数完成了动力系统和传动系的参数匹配设计。在MatLab/Simulink环境下建立基于该系统的整车性能仿真模型，进行整车动力性能及UDDS/10～15循环工况下的燃油经济性仿真计算分析，结果表明所提出的新型混合动力传动系统百公里加速时间仅为9.65 s，UDDS和10～15循环工况下的等效百公里油耗分别为4.32、3.74 L。

Abstract: A new type of power split hybrid transmission system based on metal belt-type continuously variable transmission (CVT) and planetary gear is provided. Different operation modes of the new type of hybrid transmission system are analyzed. The parameters related to power source and powertrain are designed. The vehicle performance simulation model is built under the Matlab/Simulink environment, the acceleration performance under motor driving and engine-motor combined driving as well as fuel economy under UDDS and 10～15 cycle are simulated. The simulation results show that the acceleration time is only 9.65 s from 0 to 100 km/h, and fuel consumption is 4.32 and 3.74 L under UDDS and 10～15 cyclic condition respectively.

Key words: CVT, Hybrid electric vehicle, Parameters design, Power split, Simulation
