技术方案二：
一种混合动力汽车驱动传动系统的工作方法，其工作模式包括纯电动模式、串联模式、并联模式以及功率分流模式；根据车辆的工况需求，选择不同工作模式来满足车辆的需求，同时使混合动力动力系统以及发动机处于高效的工作区域；其中，纯电模式，提供一种在发动机不提供动力时，依靠电池提供电能驱动电机单独工作，并通过变速机构实现车辆的正常行驶；其中，并联模式，发动机单独工作时，变速器结构正常传递动力，驱动车辆整车行驶，同时也已采用电机调节发动机的扭矩提高发动机的效率；其中，功率分流模式，应用发动机和电机同时工作，驱动车辆正常行驶，通过控制电机工作，调节发动机的转速以及扭矩工况点，降低发动机油耗；在车辆行驶过程中，以上几种工作模式的进行切换。
进一步地：所述纯电动模式具体工作方式如下：
纯电动模式1档：B1制动器工作结合；车辆的动力由EM1电机工作提供；动力流经路径为，EM1电机与S2太阳轮固定连接，与C2行星架上的行星齿轮进行齿轮啮合，动力传递到C2行星架和输出主动齿轮，再经齿轮啮合传递输出轴以及差速器，然后到达车辆处；根据车辆的车速与扭矩需求，调节EM1电机的工况点以满足车辆需求；EM1电机本身具备正反转的运转特性，根据车辆需求情况，实现车辆的前进档和倒挡功能；
纯电动模式2档：C1离合器和C2离合器都工作结合；车辆的动力可以由EM1电机和EM2电机共同工作提供，也可以由EM1电机或者EM2电机单独工作提供；C1离合器工作结合，将A1外齿圈和C2行星架固定连接；C2离合器工作结合，将S1太阳轮和S2太阳轮固定连接；
根据行星排运转特性，EM2电机动力经S1太阳轮及行星排轮系直驱到输出主动齿轮；EM1电机动力经S2太阳轮及行星排轮系直驱到输出主动齿轮；再经齿轮啮合传递输出轴以及差速器，然后到达车辆处。

B1制动器工作结合；车辆的动力由EM1电机工作提供；动力流经路径为，EM1电机与S2太阳轮固定连接，与C2行星架上的行星齿轮进行齿轮啮合，动力传递到C2行星架和输出主动齿轮，再经齿轮啮合传递输出轴以及差速器，然后到达车辆处。同时发动机工作，并通过EM2电机工作进行发电；发动机的动力路径为，发动机与A1外齿圈固定连接，经过行星轮系动力到S1太阳轮及EM2电机。
进一步地：所述并联工作模式具体工作方式如下：
并联模式1档：B1制定器和C2离合器都工作结合；车辆的动力主要由发动机工作提供，EM1电机和EM2电机根据整车需求以及发动机所处工况，选择驱动或者发电，对发动机的工况进行调节，让发动机处于较优的燃油消耗区；根据行星排运转特性，发动机动力经过A1外齿圈，由于B1制动器工作结合，C1行星架被固定连接，动力传递到S1太阳轮经C2离合器传递到S2太阳轮；再经过S2太阳轮与C2行星架上齿轮啮合，动力传递到C2行星架处；再经齿轮啮合传递输出轴以及差速器，然后到达车辆处。
并联模式2档：C1离合器和C2离合器都工作结合；车辆的动力主要由发动机工作提供，EM1电机和EM2电机根据整车需求以及发动机所处工况，选择驱动或者发电，对发动机的工况进行调节，让发动机处于较优的燃油消耗区；根据行星排运转特性，发动机动力分别经过A1外齿圈和C1离合器；其一部分动力经A1外齿圈进入S1太阳轮、C1行星架、A1外齿圈的行星排，再经过A2外齿圈和C2离合器传递到C2行星架；发动机另一部分动力经C1离合器直接到C2行星架；再经齿轮啮合传递输出轴以及差速器，然后到达车辆处。
进一步地：所述功率分流工作模式具体工作方式如下：

具体实施方式
为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本发明公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在申请文件中仅仅示出了与根据本发明的方案密切相关的装置结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
实施例1：参见图1，本实施例所述的一种混合动力汽车驱动传动系统，包括一组双排行星轮系、一组单排行星轮系、两组离合器、一组B1制动器2、两个电机；所述一组双排行星轮系包括S1太阳轮7、C1行星架8、A1外齿圈9；所述一组单排行星轮系包括S2太阳轮10、C2行星架11、A2外齿圈12；所述两组离合器分别为C1离合器3、C2离合器4；所述两个电机分别是EM1电机5和EM2电机6；
其中，EM2电机6的定子与壳体固定连接，EM2电机6的转子与S1太阳轮7固定连接，并且与C2离合器4的外毂固定连接；发动机1与A1外齿圈9固定相连，并且与C1离合器3的外毂固定相连；
其中，B1制动器2的外毂与壳体固定连接或者在壳体上直接铸造，B1制动器2的内毂与C1行星架8固定连接，并且与A2外齿圈12固定连接；
其中，EM1电机5的定子与壳体固定连接，EM1电机5的转子与S2太阳轮10固定连接，并且与C2离合器4的内毂固定连接；C1离合器3的内毂与C2行星架11固定连接，并且与输出主动齿轮13固定连接。
实施例2：下面结合图1说明本实施例，本实施例所述的一种混合动力汽车驱动传动系统的工作方法，其工作模式包括纯电动模式、串联模式、并联模式以及功率分流模式；根据车辆的工况需求，选择不同工作模式来满足车辆的需求，同时使混合动力动力系统以及发动机处于高效的工作区域；其中，纯电模式，提供一种在发动机不提供动力时，依靠电池提供电能驱动电机单独工作，并通过变速机构实现车辆的正常行驶；其中，并联模式，发动机单独工作时，变速器结构正常传递动力，驱动车辆整车行驶，同时也已采用电机调节发动机的扭矩提高发动机的效率；其中，功率分流模式，应用发动机和电机同时工作，驱动车辆正常行驶，通过控制电机工作，调节发动机的转速以及扭矩工况点，降低发动机油耗；在车辆行驶过程中，以上几种工作模式的进行切换。
1、纯电动模式
纯电动模式1档：B1制动器2工作结合；车辆的动力由EM1电机5工作提供；动力流经路径为，EM1电机5与S2太阳轮10固定连接，与C2行星架11上的行星齿轮进行齿轮啮合，动力传递到C2行星架11和输出主动齿轮13，再经齿轮啮合传递输出轴15以及差速器16，然后到达车辆处。根据车辆的车速与扭矩需求，调节EM1电机5的工况点以满足车辆需求。此纯电模式，EM1电机5经过二级减速，降低电机设计的最高转速要求，并且能够提升汽车的动力性能。因EM1电机5本身具备正反转的运转特性，根据车辆需求情况，可以实现车辆的前进档和倒挡功能。
纯电动模式2档：C1离合器6和C2离合器7都工作结合；车辆的动力可以由EM1电机5和EM2电机6共同工作提供，也可以由EM1电机5或者EM2电机6单独工作提供。C1离合器3工作结合，将A1外齿圈9和C2行星架11固定连接；C2离合器4工作结合，将S1太阳轮7和S2太阳轮10固定连接。
根据行星排运转特性，EM2电机6动力经S1太阳轮7及行星排轮系直驱到输出主动齿轮13；EM1电机5动力经S2太阳轮10及行星排轮系直驱到输出主动齿轮13；再经齿轮啮合传递输出轴15以及差速器16，然后到达车辆处。
纯电模式1档和2档区别在于，纯电模式1档只能提供一个EM1电机5进行驱动车辆行驶，纯电模式2档可提供两个EM1电机5和EM2电机6共同驱动车辆行驶，提升车辆的动力性以及加速性。纯电模式2档时，发动机1处于被拖动运转，可以在发动机1与变速箱间增加一个离合器，将发动机转速解耦；或者此模式根据车辆需求及控制策略进行采用，可以避免发动机被拖动运转的能量损失。
2、串联工作模式
B1制动器2工作结合；车辆的动力由EM1电机5工作提供；动力流经路径为，EM1电机5与S2太阳轮10固定连接，与C2行星架11上的行星齿轮进行齿轮啮合，动力传递到C2行星架11和输出主动齿轮13，再经齿轮啮合传递输出轴15以及差速器16，然后到达车辆处。同时发动机1工作，并通过EM2电机6工作进行发电；发动机1的动力路径为，发动机1与A1外齿圈9固定连接，经过行星轮系动力到S1太阳轮7及EM2电机6。
根据车辆的车速与扭矩需求，调节EM1电机5的工况点以满足车辆需求。发动机1通过EM2电机6进行发电，发电功率大于EM1电机5消耗功率时，可以将多余电量存储到电池中；发电功率小于EM1电机5消耗功率时，可以由电池补充需求功率或者提升发动机1的工况区域。发动机1与车速进行转速、扭矩解耦，可以将发动机选择在高效区进行工作，选择定点工作或者车辆扭矩跟随控制策略。
3、并联工作模式
并联模式1档：B1制定器2和C2离合器4都工作结合；车辆的动力主要由发动机1工作提供，EM1电机5和EM2电机6根据整车需求以及发动机1所处工况，选择驱动或者发电，对发动机1的工况进行调节，让发动机1处于较优的燃油消耗区。根据行星排运转特性，发动机1动力经过A1外齿圈9，由于B1制动器2工作结合，C1行星架8被固定连接，动力传递到S1太阳轮7经C2离合器4传递到S2太阳轮10；再经过S2太阳轮10与C2行星架11上齿轮啮合，动力传递到C2行星架11处。再经齿轮啮合传递输出轴15以及差速器16，然后到达车辆处。
并联模式2档：C1离合器3和C2离合器4都工作结合；车辆的动力主要由发动机1工作提供，EM1电机5和EM2电机6根据整车需求以及发动机1所处工况，选择驱动或者发电，对发动机1的工况进行调节，让发动机1处于较优的燃油消耗区。根据行星排运转特性，发动机1动力分别经过A1外齿圈9和C1离合器3；其一部分动力经A1外齿圈9进入S1太阳轮7、C1行星架8、A1外齿圈9的行星排，再经过A2外齿圈12和C2离合器4传递到C2行星架11。发动机1另一部分动力经C1离合器3直接到C2行星架11。再经齿轮啮合传递输出轴15以及差速器16，然后到达车辆处。
并联模式1档与2档的区别在于，发动机1的动力传递路径不同，并且发动机1到输出轴15处的速比不同。并联模式1档发动机1到输出主动齿轮13，经过两组行星排传递，变速比大于1；并联模式2档发动机1到输出主动齿轮13，经过两组行星排传递，速比等于1。
4、功率分流工作模式
C2离合器4工作结合，将S1太阳轮7与S2太阳轮10固定连接；发动机1、EM1电机8、EM2电机6都进行工作。关于转速，根据行星排运转特性，控制发动机1和EM2转速9，则EM1电机8转速即可知；或者控制发动机1和EM1转速8，则EM2电机6转速即可知。关于扭矩，根据行星排的特性，发动机1的扭矩会分配到S1太阳轮7和C1行星架8。其中一部分扭矩到S1太阳轮7和EM2电机6，经C2离合器4到S2太阳轮10和EM2电机6处，传递到C2行星架11。另一部分扭矩由C1行星架8和A2外齿圈12到C2行星架11处。由于发动机1的转速，由于受到EM1电机8或者EM2电机6转速的影响，发动机1与车辆车速的相对连续性关系，所以也称这种功率分流模式为ECVT模式。
关于功率分流模式即ECVT模式下，车辆需求与发动机1的转速、扭矩调节控制策略简述。一般情况EM1电机5作为驱动电机，EM2电机6作为发电电机；车辆的需求车速、需求扭矩作为输入量，对于各动力源的转速，可以计算EM1电机的8转速，发动机1的转速根据高效区进行预设，可以计算EM2电机6的转速。对于各动力源的扭矩，车辆需求扭矩由EM1电机5及发动机1发出扭矩构成，发动机1根据高效区预设扭矩，通过行星排传递到差速器13即车辆侧，EM1电机5发电后通过DC/DC转换器提供EM2电机6。
倒挡：本结构没有设置机械倒挡；纯电模式下，根据电机运转特性，控制电机工作的正反转用以实现车辆倒挡的功能。
虽然本发明所揭示的实施方式如上，其内容只是为了便于理解本发明的技术方案而采用的实施方式，并非用于限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所揭示的核心技术方案的前提下，可以在实施的形式和细节上做任何修改与变化，但本发明所限定的保护范围，仍须以所附的权利要求书限定的范围为准。
