Description

technical field [0001] The invention relates to the field of hybrid vehicles, in particular to a dual-motor hybrid transmission device. Background technique [0002] With the increasing shortage of oil supply and the increasing environmental pollution, the development and utilization of new energy vehicles has gradually become a trend. Among them, the hybrid electric vehicle can be driven by the engine or the motor or the engine and the motor at the same time, and has a variety of driving modes, so that the engine and the motor can operate in the high efficiency range as much as possible, so as to have good fuel economy and low emissions. [0003] Currently known dual-motor systems are representative of SAIC EDU and hybrid power transmission systems such as Toyota's E-CVT. Toyota's E-CVT includes two motors and a planetary gear transmission. Its power transmission transmission route is: [0004] 1) Engine drive: engine-first motor-planetary gear set-outer ring gear-output s...
