背景技术
本节中的陈述仅提供与本公开相关的背景信息，并且可能不构成现有技术。
车辆的环境友好技术是控制未来汽车工业的生存的核心技术，并且先进的汽车制造商已经致力于开发环境友好的车辆以符合环境和燃料效率的规定。
利用电能的电动车辆(EV)或混合动力电动车辆(HEV)或改进传动装置的效率和便利性的双离合器变速器(DCT)可以是这种未来车辆技术的实例。

在这种前进第九速度中，行星齿轮组PG输出比前进第八速度进一步增加的速度。
在“发动机和并联模式”的以上描述中，仅将发动机ENG实例为动力源。然而，显然可理解，即使电动机/发电机MG被激活以形成并联模式并辅助发动机ENG，也可保持这种变速操作。
电动车辆模式EV模式与发动机和并联模式不同，仅在于发动机ENG在释放发动机离合器ECL时停止并且仅电动机/发电机MG用作唯一电源。可理解的是，这种差异不会影响上述变速操作，并且因此，在这种电动车辆模式EV模式中，前进第一速度FD1到前进第九速度FD9的一个后退速度REV和九个前进速度的相同变速档可通过相同的操作图获得。
根据本公开的示例性形式的用于车辆的动力传动装置通过将行星齿轮组和两个同步器应用于多个离合器传动设备来实现九个前进速度和一个后退速度的变速档，从而通过简化的布置实现多个变速档，改善可安装性并减小整体重量。
此外，本公开的示例性形式可从电动机/发电机以及发动机接收扭矩，使得车辆可以以电动车辆模式和并联混合动力模式行驶，从而改善燃料消耗。
虽然已经结合目前被认为是实用的示例性形式描述了本公开，但是应该理解，本公开不限于所公开的形式，而是相反地，旨在覆盖包括在本公开的精神和范围内的各种修改和等同布置。
