In order to solve the technical problem that an existing dual-output transmission automatic transmission has high requirements for synchronous control precision of two motors, the invention provides adual-output transmission automatic transmission. A special transmission line is designed, as long as three planet rows meet a specific speed ratio relation, it can be guaranteed that the rotating speed of the first output shaft and the rotating speed of the third output shaft are the same in a straight moving mode, and the requirement for the synchronous control precision of the two driving motors is avoided; moreover, an internal combustion engine or a driving motor can be switched to provide power according to different working conditions, and when the power provided by the internal combustion engine is excessive, the first driving motor can be changed into a generator to convert and store excessive energy or provide the excessive energy to the second driving motor, so that the internalcombustion engine can always work at the position of the optimal efficiency point, and the fuel economy is ensured.

    为了解决现有双输出传动的自动变速器,对两个电机的同步控制精度要求较高的技术问题,本发明提供了一种双输出传动的自动变速器。本发明设计了特殊的传动路线,只要三个行星排满足特定的速比关系,则在直行模式下即可保证第一输出轴和第三输出轴的转速相同,对两个驱动电机的同步控制精度没有要求;并且,本发明可根据不同工况,切换内燃机或者驱动电机提供动力,当内燃机提供动力过剩时,第一驱动电机可变为发电机,将多余能量转换储存或提供给第二驱动电机,这样可以始终使内燃机工作在最佳效率点的位置,保证燃油经济性。
