本发明一实施例中，如图1所示，混合动力驱动系统10，包括发电机1、发动机2、电动机3、同步器4、差速器5、减速器8和离合器单元7；
离合器单元7设置在发电机1与发动机2之间，离合器单元7还设置在发动机2与减速器8之间，电动机3与差速器5之间设有同步器4和减速器8，差速器5用于传输动力给两个车轮20；
离合器单元7包括离合器控制器73、第一离合器71和第二离合器72，第一离合器71与减速器8传动，第二离合器72与发电机1传动。
具体为，发动机2与扭矩减振器6连接，扭矩减振器6连接离合器单元7，离合器单元7包括了第一离合器71和第二离合器72，第二离合器72与发电机1传动，第一离合器71与减速器8传动，同步器4用于换挡减速器8，同步器4连接电动机3，减速器8连接差速器5，差速器5将动力传输给两个车轮20。
其中，离合器单元7还包括离合器控制器73，离合器控制器73用于控制第一离合器71和第二离合器72的结合和断开。
减速器8包括第二传动齿轮02、第三传动齿轮03、第六传动齿轮06和第七传动齿轮07。
增速器包括第四传动齿轮04和第五传动齿轮05。
第一离合器71通过第一传动齿轮01、第二传动齿轮02和第一传动轴11与同步器4连接；第二传动齿轮02与第三传动齿轮03传动，第三传动齿轮03与差速器5传动，差速器5将动力传输给两个车轮20。
第二离合器72通过第二传动轴12、第四传动齿轮04和第五传动齿轮05与发电机1传动。
同步器4通过第六传动齿轮06和第七传动齿轮07与电动机3传动，同步器4工作时可做档位切换。因此，第二离合器72能够实现发动机2与发电机1之间的连接或断开，第一离合器71能够实现发动机2与同步器4的连接或断开，进而实现与电动机3或差速器5的连接或断开。
本实施例中在发动机2与发电机1之间增加第二离合器72，当电池不需要充电发动机2参加驱动时，可以断开与发电机1的连接，避免能源浪费。并且双档结构设计，能够实现高速经济档与动力档，提升整车的动力性与经济性。
进一步地，如图1所示，混合动力驱动系统包括纯电模式，第一离合器71和第二离合72器均断开，发动机2和发电机1不工作，电动机3驱动差速器5带动车轮20转动。
图1中的空心箭头表示动力传输方向。
具体为，当第二离合器72断开时，发动机2与发电机1之间的连接断开；当第一离合器71断开时，发动机2与同步器4之间的连接断开。
因此，发动机2和发电机1均不工作，此时只有电动机3工作，电动机3的动力从第六传动齿轮06和第七传动齿轮07传递到同步器4，再从同步器4传递到第二传动齿轮02、第三传动齿轮03和差速器5处，最后从差速器5传递到两个车轮20上，实现纯电模式。
进一步地，如图2所示，混合动力驱动系统包括串联模式，第一离合器71断开，第二离合器72结合，发动机2与发电机1工作发电，电动机3驱动差速器5带动车轮20转动。
图2中的空心箭头表示动力的传递方向。
由于第一离合器71断开，因此发动机2与同步器4之间断开；第二离合器72结合，发动机2的动力通过第二离合器72传动到第二传动轴12、第四传动齿轮04和第五传动齿轮05，最后带动发电机1发电。
而电动机3的动力传输路径与纯电模式中相同，驱动车轮20转动。
此时，为混合动力驱动系统的串联模式。
进一步地，如图3所示，混合动力驱动系统包括并联模式，第一离合器71结合，发动机2与电动机3共同驱动差速器5带动车轮20转动。
由于第一离合器71结合，发动机2的动力通过第一离合器71、第一传动齿轮01、第二传动齿轮02和第三传动齿轮03传递到差速器5处；
同时电动机3的动力传输路径与纯电模式中相同。
发动机2和电动机3共同驱动差速器5带动车轮20转动。
进一步地，如图3所示，并联模式包括第一子模式和第二子模式；
第一子模式时，第二离合器72结合，发电机1与发动机2工作发电；
图3中的黑色实心箭头表示第一子模式下，发动机2带动发电机1发电的工作路径。
第二子模式时，第二离合器72断开，发电机1不工作。
第二子模式时，由于第二离合器72断开，发动机2与发电机1之间断开，发电机1不工作。图3中的黑色实心箭头的工作路径在第二子模式下不执行。
第二子模式时，由于发电机1不工作，没有发电端的拖拽，优化经济性与动力性，解决了发电机1消耗浪费发动机2动力的问题。
进一步地，如图4所示混合动力驱动系统包括发电模式，第一离合器71断开，第二离合器72结合，发电机1与发动机2工作发电。
由于第一离合器71断开，发动机2与同步器4之间断开；第二离合器72结合，发动机2通过第二离合器72、第二传动轴12、第四传动齿轮04和第五传动齿轮05带动发电机1发电。
此时，电动机3不工作，车轮20不转动。
进一步地，如图5所示，混合动力驱动系统包括动力补偿模式，第一离合器71结合，第二离合器72断开，电动机3调速空转做换档前准备，同步器5左右切换换挡，发动机2做动力补偿输出。
由于第二离合器72断开，发动机2与发电机1之间断开；
第一离合器71结合，发动机2的动力经过第一离合器71、第一传动齿轮01、第二传动齿轮02和第三传动齿轮03达到差速器5。
此时，电动机3调速空转做换档前准备，同步器5左右切换换挡，发动机2做动力补偿输出，解决了换挡时电动机动力中断造成的冲击问题。
进一步地，如图6所示，混合动力驱动系统包括发动机直驱模式，第一离合器71结合，第二离合器72断开，同步器4空挂，发电机1与电动机3不工作，发动机2直接驱动差速器5带动车轮20转动。
与动力补偿模式不同的是，同步器5空挂，电动机3不工作，发动机2直接驱动差速器5带动车轮20转动。通过同步器4的断开与电动机3的连接，解决了发动机2驱动时拖曳电动机3造成的能量损耗，优化经济性与动力性。
本发明另一实施例中，还包括总成壳体，第一离合器71、第二离合器72和减速器8均设置在总成壳体内，发动机2、发电机1和电动机3与总成壳体连接。
发动机2的传动轴通过减振器与离合器连接，防止拖曳发电机1，起到避免能源浪费的作用。另外，双离合器布置在同侧，轴向距离短，改善布置空间，结构紧凑。
本发明具有以下优点：
1.两档机构：改善经济性与动力性；
2.双离合器布置：同侧布置，轴向距离短，改善布置空间，结构紧凑；
