摘　　要：通过分析传统对称式汽车差速器的传递特性,建立了其作为动力耦合器的数学模型,开发了基于差速耦合的整车控制策略,并嵌入到ADVISOR与整车模型进行集成。以某混合动力轿车为例进行性能仿真,结果表明:应用此对称式锥齿轮差速器除具有节能优势外,取消变速器与离合器,并具有电控无级自动变速的功能(ECVT),从而达到了整车混联式传递灵活、多自由度可控制的目的。The transmission characteristic of the traditional symmetrical level gear differential was analyzed and it was modelled mathematically as a power coupler. A control strategy was developed for the differential coupling hybrid electric vehicle （HEV） and embedded into the ADVISOR vehicle model. Taking a certain hybrid electric car as an example, the performance simulation was performed. The results showed that the differential coupling parallel-series HEV can not only save fuel, but also abandon the use of the gearbox and the clutch. It possesses the function of the electronic continuously variable transmission with flexible transmission and multi-DoF controllability.
