汽车工业作为国民经济的重要支柱，近年来得到了快速发展。但同时也带来了能源消耗和环境污染等问题。机电式无级变速系统被认为是可行的解决方案之一。提出了一种双模式机电无级变速传动系统转速特性和双模式传动图的设计方法。根据电机四象限运行的运行特性和简单内外啮合单行星轮系的速度特性，设计了4种双模式机电传动系统方案。并对其中一种方案的速度、转矩和功率特性进行了分析。电动分流功率的大小是影响系统性能的重要因素，因此在参数匹配设计时，需要降低电机第一模式下的功率需求。电机、输出转速范围和模式切换点的位置与行星齿轮组的特性设计有关。该分析方法可为混合动力汽车的设计提供参考。由于所涉及的转速和转矩关系是传动系统各部分的自然联系，为系统规划和性能分析提供了理论依据。
Automotive industry, as an important pillar of the national economy, has been rapidly developing in recent years. But proplems such as energy comsumption and environmental pollution are posed at the same time. Electro-mechanical variable transmission system is considered one of avilable workarounds. It is brought forward a kind of design methods of dual-mode electro-mechanical variable transmission system rotational speed characteristics and dual-mode drive diagrams. With the motor operating behavior of running in four quadrants and the speed characteristics of the simple internal and external meshing single planetary gear train, four kinds of dual-mode electro-mechanical transmission system scheme are designed. And the velocity, torque and power characteristics of one of the programs are analyzed. The magnitude of the electric split-flow power is an important factor which influences the system performance, so in the parameters matching design, it needs to reduce the power needs under the first mode of the motor. The motor, output rotational speed range and the position of the mode switching point have relationships with the characteristics design of the planetary gear set. The analysis method is to provide a reference for hybrid vehicles’ design. As the involved rotational speed and torque relationships are the natural contact of every part of transmission system, a theory basis of system program and performance analysis is provided.
