目前销售的大多数混合动力电动车辆（HEV）是功率分流式HEV，其使用单个、双个或偶尔甚至多个行星齿轮（PG）组来连接其动力传动系元件。添加PG组可以提供更大的设计灵活性;但是，它也会增加系统复杂性和成本。本文提出了一种比较研究的混合动力系统与不同数量的PG集，我们术语的配置。定性和定量地研究了不同构型类型的分析。在定性分析中，不同配置的操作模式的性能进行了比较，在模式数，归一化效率，和最大输出转矩。定量方法比较不同配置的设计;所有上级设计的燃油经济性和加速性能进行评估，使比较标志性。结果表明，与双PG混合动力车相比，三PG混合动力车的燃油经济性没有显着提高，但它们在加速性能方面取得了显着改善;这对运动型多用途车（SUV），轻型卡车和公共汽车是有益的。出于成本考虑，建议乘用汽车采用双PG混合动力系统。
Most hybrid electric vehicles (HEVs) currently sold are power-split HEVs that use single, double or occasionally even multiple planetary gear (PG) sets to connect their powertrain elements. Adding PG sets can provide more design flexibility; however, it also increases system complexity and cost. This paper presents a comparative study of hybrid powertrains with different numbers of PG sets, which we term configurations. The analysis of different configuration types is investigated both qualitatively and quantitatively. In the qualitative analysis, the performances of operating modes for different configurations are compared, in terms of mode number, normalized efficiency, and maximum output torque. The quantitative approach compares the designs of different configurations; the fuel economy and acceleration performance of all superior designs are evaluated to make the comparison iconic. The results show that triple-PG hybrids do not have significant fuel economy improvement compared with double-PG hybrids, but they achieve a dramatic improvement in acceleration performance; this can be beneficial for sport utility vehicles (SUVs), light trucks, and buses. For cost consideration, it is suggested that passenger cars adopt double-PG hybrid powertrains.
