在混合动力驱动模式时，闭合第一离合器使发动机输出的动力通过输入轴传递至行星架，此时动力系统以动力分流工作模式运行，作为主要的混合动力模式。在该模式下，通过控制第一电机的工作转速，调节发动机的工作点，使得发动机能够稳定在高效区间，此时第一电机处于发电状态，电能存入电池或供给第二电机使用。动力分流模式能够使发动机转速与车速解耦，发动机能够长时间工作在最优区间，而且还能通过电机的转速控制实现整车无级变速，即E-CVT功能，这也是动力分流混合动力系统的方案优势。
在混合动力高车速行驶时，发动机自身可以工作在高效区间，此时再闭合第二离合器，动力系统实现固定传动比驱动模式，此时发动机单独驱动或同时与两个电机或与其中一个电机共同驱动车辆。
在混合动力传动装置的基础上，通过去除与发动机连接的输入轴、第一离合器，能够形成一种纯电动传动装置，可以根据需要进行不同速比的调整，同时采用单电机或者双电机工作模式，以满足不同的工况需求；另外，在产品进行批量化生产过程中，纯电动传动装置与混合动力传动装置，其零部件通用度高，能够节省大量的制造成本，有助于实现产品的系列化开发。
通过以上分析，本发明提供的混合动力的传动装置，能够实现两挡纯电动驱动模式，能够满足低速大扭矩和高车速的使用要求，尤其适用于插电混合动力系统；在混合动力驱动模式下，中低速时采用动力分流模式，实现良好的燃 油经济性；高车速时采用固定速比驱动模式，充分利用发动机自身的高效运行区间；本发明所提供的纯电动传动装置，能够用于两挡纯电动变速箱，结合混合动力传动装置和纯电动传动装置来看，能够实现产品的平台化和系列化。
而且，本发明提供的传动装置结构简单，且无需通过大功率高扭矩的驱动电机来满足动力需求，从而降低传动装置的成本。

注：○——表示打开状态；●——表示闭合状态
依据上表对本实施例提供的传动装置的工作模式作进一步的说明：
一、纯电动驱动模式：
在纯电动驱动模式下，结合表1，将制动器B1闭合，第一离合器C2和第二离合器C1开启，此时：
(ⅰ)第一电机单独工作时，能够带动所述第一电机轴13进行转动，通过第一电机轴13能够驱动第一减速齿轮副进行转动，从而将动力传递至套轴6上，由于套轴6与太阳轮3相连接，通过套轴6能够将动力传递至太阳轮3，又由于制动器B1与行星架2相连接，利用制动器B1能够锁止行星架2，从而使动力传递至齿圈5，进而传递至于齿圈5相连接的连轴7，通过连轴7传递至于其相连接的输出轴上；
(ⅱ)第二电机单独工作时，能够带动第二电机轴14进行转动，将动力通过第二电机轴14传递至第三减速小齿轮12，进而传递至与第三减速小齿轮12相啮合的第二减速大齿轮11，由于所述连轴7与第二减速大齿轮11相连接，因此动力能够传递至连轴7，从而通过连轴7传递至输出轴20上；
(ⅲ)结合(ⅰ)和(ⅱ)两种情况，通过第一电机和第二电机共同工作，能够带动连轴7进行转动，进而驱动输出轴进行转动。
通过以上三种情况中的任一情况，能够形成第一固定的传动比，形成电机模式1，需要说明的是，当所述第一电机和所述第二电机同时工作时，能够输出较大的驱动扭矩，充分满足纯电动的动力性需求。
在第一电机与第二电机同时工作时，当车速增加的情形下，为了防止第一电机转速过高，此时打开制动器B1，调节第一电机的转速，使第一电机的转速接近或者等同第二电机的转速，然后闭合第一离合器C1，此时，第一电机通过第一电机轴13能够带动第二减速齿轮副进行转动，从而驱动连轴7进行转动，连轴7将动力传递至输出轴，此时能够形成第二固定的传动比。
另外，通过设置第一减速齿轮副传动比与第二减速齿轮副传动比相同，当第一离合器C2闭合时，太阳轮3的转速和齿圈5的转速将同速运行，及行星排的各元件之间没有相对转速，这样能够降低行星排运行的机械损失。
二、混合动力驱动模式：
在混合动力驱动模式下，结合上表，打开制动器B1和第一离合器C2，闭合第二离合器C1，当第一电机工作时，通过第一电机能够带动第一电机轴13转动，驱动第一减速齿轮副进行转动，第一减速齿轮副能够将动力传递至太阳轮3，由于制动器处于打开状态，第二离合器C1处于闭合状态，太阳轮3将动力传递至行星轮4，进而通过行星架2将动力传递至发动机，能够带动发动机启动，同时调节发动机的工作点，实现发动机转速与车速解耦；
发动机在工作状态下，通过第一输入轴1能够将动力传递至第二输入轴19，由于制动器B1处于打开状态，且第二输入轴19与行星架2相连接，通过利用第二输入轴19能够带动齿圈5和太阳轮3分别进行转动，通过齿圈5的转动能够驱动连轴7进行转动，从而使输出轴20进行转动。
需要说明的是，当发动机进行工作时，能够带动太阳轮3转动，从而通过第一减速齿轮副带动第一电机轴13进行转动，此时，第一电机能够从发动机获得部分功率，第一电机处于发电状态，能够将电能存入电池或供给第二电机使用，形成完整的电功率传递路径，发动机的其余功率将通过行星排机构的机械路径传递至输出轴。
第二电机通过驱动第二电机轴14能够驱动第三减速齿轮副进行运转，带动连轴7进行转动，从而将动力传递至输出轴20，与发动机共同提供动力输出。
在此模式中，发动机的输出功率经过电功率传递路径和机械传递路径传递，实现了动力分流工作模式，该动力分流的工作模式优化了发动机的工作区间，使得动力系统整体获得受益，具有良好的燃油经济性。
当车辆处于高速行驶时，由于发动机自身可以工作在高效区间，此时闭合第一离合器C2和第二离合器C1，打开制动器B1，动力系统能够实现固定的传动比驱动模式，即通过利用发动机单独驱动，或者发动机与第一电机共同驱动，或者发动机与第二电机共同驱动，或者发动机与第一电机、第二电机共同驱动，即能够形成该固定的传动比驱动模式。
由上可知，本发明提供的传动装置，可根据车辆不同工况智能化切换不同运行模式，在满足整车驱动要求的前提下保证整车的经济性和排放性，发动机时刻处于高效率运行状态，车辆经济性和排放性处于最佳状态；起步阶段，双电机纯电行驶，低速阶段双电机纯电驱动、中低速阶段行星排混动行驶，高速阶段，并联混动模式，怠速阶段发动机停机，制动阶段能量回馈
