具体地，电机总成4包括：电机4-1及减速器4-2。
减速器4-2的第一端与电机4-1连接，减速器4-2的第二端与第二输入轴2连接。
电机4-1的动力可通过减速器4-2传递给第二输入轴2，利用电机扭矩补偿可以填充发动机扭矩掉坑，保证整车加速度的连续平稳，提高换挡舒适性。
当需要倒车时，电机4-1反转，将动力传递给第二输入轴2，第二输入轴2通过二档主动齿轮5将动力传递给二档从动齿轮9，二档从动齿轮9与输出轴3结合，将动力传递给输出轴3，实现倒车。
具体地，混合动力变速器还包括：离合装置16。
离合装置16包括：第一离合器16-1及第二离合器16-2。
第一离合器16-1与第一输入轴1连接。
第二离合器16-2与第二输入轴2连接，且，第二输入轴2设置在第一输入轴1内，第二输入轴2与第一输入轴1同轴，第二离合器16-2控制一档、三档和五档；第一离合器16-1控制二档，四档和六档，实现双离合器结构。
电机总成4与第二输入轴2连接，即电机总成4与双离合器结构组合产生P2.5混动结构，可以实现发动机直驱，启动，能量回收，纯电起步，驻车发电，纯电行驶，并联行驶。双离合器结构和P2.5混动结构可以实现并联加速助力，提高动力性；混动模式可以实现纯电启动，制动能量回收，提高燃油经济性；双离合器换挡过程中，电机可以进行扭矩补偿，提高驾驶舒适性和动力响应性。
双离合器结构配合P2.5的构型，可以实现7种混动模式，见表1。7种混动模式可以丰富整车控制策略的选择。通过整车能量管理策略能够找到最优的控制策略，以降低车辆油耗，提高车辆燃油经济型性；除优化燃油经济性外，7种混动模式的助力模式能提升整车动力性；升档过程中的电机扭矩填充功能可以保证加速度连续，提升驶舒适性。

表1：混动动力功能实现途径
参见图4，当进行驻车固定速比充电时，第二离合器16-2将动力传递给第二输入轴2，第二输入轴2通过电机总成4的减速器4-2将动力传递给电机4-1，对电机4-1进行充电。参见图5，当进行驻车增速充电时，第一离合器16-1将动力传递给第一输入轴1，第一输入轴1带动四档主动齿轮7动作，四档主动齿轮7将动力传递给四档从动齿轮11，四档从动齿轮11与三档从动齿轮10结合，将动力通过三档从动齿轮10传递给三档主动齿轮6，三档主动齿轮6达到第二输入轴2动作，第二输入轴2通过电机总成4的减速器4-2将动力传递给电机4-1，对电机4-1进行充电。
加速助力和制动能量回收工作原理：双离合器变速箱为了实现无动力中断换挡，开发控制策略上有预选档策略，例如第二离合器16-2传递力矩，三档为行驶档，双离合器换挡控制策略会预选二档或者四档。双离合器变速箱的预选档控制策略会同时挂上2个档位(1个奇数档，1个偶数档)，所有档位共用一个输出轴3。输出轴3在转动的时候，第一输入轴1与第二输入轴2会一起转动。无论是奇数档在档，还是偶数档是当前行驶档位，第一输入轴1与第二输入轴2都会转动。电机总成4的电机4-1通过减速器4-2与第二输入轴2(奇数档)连接，随时可以提供助力或者制动能量回收。电机加速助力和制动能量回收都不需要换挡，执行性好，回收效果好。
例如车辆以4档行驶，即4档在档行驶，预挂3档工况。参见图6，四档加速助力，即：电机总成4的电机4-1通过减速器4-2将动力传递给第二输入轴2，第二输入轴2通过三档主动齿轮6带动三档从动齿轮10，三档从动齿轮10与输出轴3结合，将动力传递给输出轴3，同时，第一离合器16-1将动力传递给动力传递给第一输入轴1，第一输入轴1通过四档主动齿轮7将动力传递给四档从动齿轮11，四档从动齿轮11与输出轴3结合，将动力传递给输出轴3。参见图7，四档能量回收，即：轮端能量传递给输出轴3，输出轴3与三档从动齿轮10结合，三档从动齿轮10将动力传递给三档主动齿轮6，三档主动齿轮6带动第二输入轴2动作，第二输入轴2通过电机总成4的减速器4-2将动力传递给电机4-1，实现能量回收。
具体地，混合动力变速器还包括：差速器17。
差速器17与输出轴3连接，用于接收输出轴3传递的动力。
具体地，混合动力变速器还包括：箱体。
第一输入轴1、第二输入轴2、输出轴3、电机总成4、二档主动齿轮5、三档主动齿轮6、四档主动齿轮7、五档主动齿轮8、二档从动齿轮9、三档从动齿轮10、四档从动齿轮11及五档从动齿轮12均设置在箱体内，通过箱体容纳第一输入轴1、第二输入轴2、输出轴3、电机总成4、二档主动齿轮5、三档主动齿轮6、四档主动齿轮7、五档主动齿轮8、二档从动齿轮9、三档从动齿轮10、四档从动齿轮11及五档从动齿轮12，保证安全。
