本申请实施例提供的车辆混合动力总成，通过将两个电机与发动机结合，无需结合现有的发动机变速箱，第一变速机构601和第二变速机构602分别连接两个输入轴和中间轴10，第一同步器21可连接三档齿轮组17的三档从动轮171和中间轴10，结构简单，传动效率高。而且在车辆低速行驶时，可通过发动机3驱动车辆，为车辆提供较大的扭矩，避免造成电机过热，在车辆高速行驶时，可通过第二电机5驱动，两档齿轮组能够满足车辆的不同速度需求，在发动机3和两个电机同时工作时，发动机3可驱动第一电机4发电，进而在车辆行驶的过程中为蓄电池1充电，增加车辆的续航里程。本申请中的两个输出轴可以使车辆处于前驱状态或四驱状态，驾驶时可以根据需要调整车辆为前驱模式或四驱模式，满足不同的驾驶需求。
为使本申请的技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
如图1所示，该车辆混合动力总成包括蓄电池1、逆变器2、发动机3、第一电机4、第二电机5和变速箱6，其中第一电机4和第二电机5均与逆变器2电连接，逆变器2与蓄电池1电连接，蓄电池1通过逆变器2为第一电机4和第二电机5供电，或仅为第二电机5供电，发动机3、第一电机4和第二电机5与变速箱6相连。
具体地，参见图1-3，该变速箱6包括第一离合器61、第二离合器62、第 一输入轴8、第二输入轴9、中间轴10、第一输出轴25、第二输出轴26、后驱动轴27、第一变速机构601和第二变速机构602。其中，第一输入轴8与第二电机5相连，第一离合器61的第一部分611与发动机3相连，第一离合器61的第二部分612与第二输入轴9相连，第一离合器61的第二部分612被配置为第一电机4的转子，第二离合器62的第一部分621与中间轴10相连，第二离合器62的第二部分622与后驱动轴27相连。当第一离合器61被配置为接合状态时，发动机3输出的动力可传递至第二输入轴9，当第二离合器62被配置为接合状态时，中间轴10输出的动力可传递至后驱动轴27。第一输入轴8、第二输入轴9与中间轴10平行设置，第一输出轴25和第二输出轴26垂直于中间轴10。第一输入轴8通过第一变速机构601传动至中间轴10，第二输入轴9通过第二变速机构602传动至中间轴10。
在本申请的一些实施例中，如图1所示，第二变速机构602可包括一档齿轮组15和第二同步器22，一档齿轮组15的一档主动轮151与第二输入轴9同轴相连，一档齿轮组15的一档从动轮152和第二同步器22套设在中间轴10外，第二同步器22用于使一档齿轮组15的一档从动轮152和中间轴10相连或断开连接。
在本申请的一些实施例中，如图1和3所示，变速箱6还可包括第一螺旋伞齿轮组23和第二螺旋伞齿轮组24，中间轴10与第一输出轴25通过第一螺旋伞齿轮组23传动连接，后驱动轴27与第二输出轴26通过第二螺旋伞齿轮组24传动连接。
需要说明的是，第一电机4为发电电动机，第二电机5为电动机。当发动机3工作且第一离合器61的第一部分611与第二部分612接合时，第一离合器61的第二部分612旋转，同时第一离合器61的第二部分612被配置为第一电机4的转子。若第一电机4接入负载，则第一离合器61的第二部分612使第一电机4处于发电状态，其产生的电能可通过逆变器2储存至蓄电池1中。若第二电机5同时处于工作状态，第一电机4产生的电能可通过逆变器2直接传递给第二电机5，或通过逆变器2储存至蓄电池1中，蓄电池1再给第二电机5 供电。
当发动机3工作且第一离合器61的第一部分611与第二部分612接合时，发动机3产生的动力传递至第二输入轴9。若第一电机4不工作，即第一电机4未接入负载，第一电机4只产生极小的电能，进而只对发动机3施加极小的负载。
在本申请的一些实施例中，如图2-3所示，该车辆混合动力总成还可包括前差速器13和后差速器14，第一输出轴25的输出端设置有前输出齿轮组19，第二输出轴26的输出端设置有后输出齿轮组20，第一输出轴25和第二输出轴26分别通过前输出齿轮组19和后输出齿轮组20传动至前差速器13和后差速器14，以带动前传动轴11和后传动轴12。其中前差速器13和后差速器14能够使其两侧的传动轴以不同的速度旋转，满足车辆曲线行驶时的需要。
具体地，如图1所示，第二变速机构602还可包括二档齿轮组16，二档齿轮组16的传动比不同于一档齿轮组15，如一档齿轮组15的传动比可小于二档齿轮组16。一档齿轮组15包括一档主动轮151和一档从动轮152，二档齿轮组16包括二档主动轮161和二档从动轮162，一档主动轮151和二档主动轮161分别与第二输入轴9同轴相连，一档从动轮152和二档从动轮162分别套设在中间轴10外。当第二输入轴9旋转时，一档主动轮151、一档从动轮152、二档主动轮161和二档从动轮162旋转，中间轴10可随一档从动轮152或二档从动轮162旋转。
在本申请的一些实施例中，如图1所示，第一变速机构601还可包括四档齿轮组18，四档齿轮组18的传动比不同于三挡齿轮组17，如三档齿轮组17的传动比可小于四档齿轮组18。三档齿轮组17包括三档主动轮172和三档从动轮171，四档齿轮组18包括四档主动轮182和四档从动轮181，三档主动轮172和四档主动轮182分别与第一输入轴8同轴相连，三档从动轮171和四档从动轮181分别套设在中间轴10外。当第一输入轴8旋转时，中间轴10可随三档从动轮171或四档从动轮181旋转。
可以理解的是，为实现变速箱6在不同传动比之间的切换，二档从动轮162 位于第二同步器22远离一档从动轮152的一侧，即一档从动轮152与二档从动轮162之间设置有第二同步器22，第二同步器22用于使一档从动轮152或二档从动轮162与中间轴10相连或断开连接，且一档从动轮152和二档从动轮162至多有一个与中间轴10相连。四档从动轮181位于第一同步器21靠近三挡从动轮171的一侧，即三档从动轮171与四档从动轮181之间设置有第一同步器21，第一同步器21用于使三档从动轮171或四档从动轮181与中间轴10相连或断开连接，且三档从动轮171和四档从动轮181至多有一个与中间轴10相连。当第二同步器22与一档从动轮152接合时，第二输入轴9通过一档齿轮组15将动力传递至中间轴10。当第二同步器22与二档从动轮162接合时，第二输入轴9通过二档齿轮组16将动力传递至中间轴10；当第一同步器21与三档从动轮171接合时，第一输入轴8通过三档齿轮组17将动力输出至中间轴10。当第一同步器21与四档从动轮181接合时，第一输入轴8通过四档齿轮组18将动力输出至中间轴10。当第二同步器22位于一档从动轮152与二档从动轮162之间，且第一同步器21位于三档从动轮171与四档从动轮181之间时，车辆处于空档状态。
需要说明的是，第一同步器21和第二同步器22由车辆的换档操纵机构控制，可使第二同步器22与一档从动轮152或二档从动轮162接合，或使第一同步器21与三档从动轮171或四档从动轮181接合。
第二方面，本申请实施例还提供了一种车辆混合动力总成控制方法，由整车控制器控制上述的车辆混合动力总成。该车辆混合动力总成控制方法包括：
将该车辆混合动力总成配置为发动机模式，在该模式下，发动机3工作，第一电机4和第二电机5不工作。
可选地，将该车辆混合动力总成配置为发动机模式可包括：控制第一离合器61的第一部分611与第二部分612接合，第二同步器22与一档从动轮152或二档从动轮162接合，第一同步器21处于中间位置。
在车辆起步或爬坡时，车辆需要较大的扭矩，整车控制器可将车辆混合动力总成配置为发动机模式，由发动机3为车辆提供动力，避免第一电机4或第 二电机5过热，影响车辆的整体性能和安全，提高电机的使用寿命。在车辆以相对较低的速度行驶时，整车控制器控制换档操纵机构使第二同步器22与一档从动轮152接合，中间轴10能够输出较大的扭矩和较低的转速；在车辆以相对较高的速度行驶时，整车控制器控制换档操纵机构使第二同步器22与二档从动轮162接合，中间轴10能够输出较小的扭矩和较高的转速。
需要说明的是，上述发动机模式还可包括控制第二离合器62的第一部分621与第二部分622接合。通过此方式，中间轴10输出的动力通过后驱动轴27传递至第二输出轴26，从而驱动车辆的后传动轴12，实现四轮驱动，进一步增加车辆的动力。并且，在发动机模式下，作为第一电机4的转子的第一离合器61的第二部分612在发动机3的作用下旋转，第一电机4不工作，即第一电机4未接入负载，转子的旋转不会增大发动机3的负载。
在本申请的一些实施例中，该车辆混合动力总成控制方法还可包括：
将车辆混合动力总成配置为纯电动模式，在该模式下，第二电机5工作，发动机3和第一电机4不工作。
可选地，将车辆混合动力总成配置为纯电动模式可包括：控制第一离合器61的第一部分611与第二部分612接合，第一同步器21与三档从动轮171或四档从动轮181接合，第二同步器22处于中间位置。
需要说明的是，上述纯电动模式还可包括控制第二离合器62的第一部分621与第二部分622接合。通过此方式，中间轴10输出的动力通过后驱动轴27传递至第二输出轴26，从而驱动车辆的后传动轴12，实现四轮驱动，进一步增加车辆的动力。
在本申请的一些实施例中，该车辆混合动力总成控制方法还可包括：
将车辆混合动力总成配置为第一混合动力模式，在该模式下，发动机3、第一电机4和第二发动机5工作。
可选地，将车辆混合动力总成配置为第一混合动力模式可包括：控制第一离合器61的第一部分611与第二部分612接合，第一同步器21与三档从动轮171或四档从动轮181接合，第二同步器22处于中间位置。
通过此方法，第二电机5输出的动力可传递至第一输出轴25，当车辆以相对较低的速度行驶时，整车控制器控制换档操纵机构使第一同步器21与三档从动轮171接合，中间轴10能够输出相对较低的转速。在车辆以相对较高的速度行驶时，整车控制器控制换档操纵机构使第一同步器21与四档从动轮181接合，中间轴10能够输出相对较高的转速。同时，第一离合器61的第二部分612旋转，使第一电机4处于发电状态，第一电机4产生的电能通过逆变器2储存在蓄电池1中。在蓄电池1剩余电能不充足的情况下，此方法可为蓄电池1补充电能，延长车辆的行驶里程，满足长途行驶的需要。
需要说明的是，上述第一混合动力模式还可包括控制第二离合器62的第一部分621与第二部分622接合。通过此方式，中间轴10输出的动力通过后驱动轴27传递至第二输出轴26，从而驱动车辆的后传动轴12，实现四轮驱动，进一步增加车辆的动力。
在本申请的一些实施例中，该车辆混合动力总成控制方法还可包括：
将车辆混合动力总成配置为第二混合动力模式，在该模式下，发动机3、第一电机4和第二发动机5工作。
可选地，将车辆混合动力总成配置为第二混合动力模式可包括：控制第一离合器61的第一部分611与第二部分612接合，第二同步器22与一档从动轮152且第一同步器21与三档从动轮171接合，或第二同步器22与二档从动轮162接合且第一同步器21与四档从动轮181接合。其中，一档从动轮152与三档从动轮171具有相同的转速，二档从动轮162与四档从动轮181具有相同的转速。
在车辆需要较大的动力时，可将车辆调整为第二混合动力模式，此时发动机3、第一电机4和第二电机5均将动力输出至中间轴10，当车辆以相对较低的速度行驶时，整车控制器控制换档操纵机构使第二同步器22与一档从动轮152接合，第一同步器21与三档同步器172接合，中间轴10能够输出相对较低的转速；在车辆以相对较高的速度行驶时，整车控制器控制换档操纵机构使第二同步器22与二档从动轮162接合，第一同步器21与四档从动轮181接合， 中间轴10能够输出相对较高的转速。此方法可为车辆提供更大动力，可以满足驾驶时对车辆较大的动力的需求。
需要说明的是，上述第二混合动力模式还可包括控制第二离合器62的第一部分621与第二部分622接合。通过此方式，中间轴10输出的动力通过后驱动轴27传递至第二输出轴26，从而驱动车辆的后传动轴12，实现四轮驱动，进一步增加车辆的动力。
第三方面，本申请实施例还提供了一种车辆，该车辆包括上述的车辆混合动力总成，并能够执行上述的车辆混合动力总成控制方法。
当该车辆处于行驶的起步阶段或爬坡时，整车控制器自动将车辆动力总成调整为发动机模式，为车辆提供更大的动力。并且随着车辆行驶速度的增加，整车控制器控制换档机构使第二同步器22与二档从动轮162接合，以提高车辆的行驶速度并降低发动机3的油耗。当该车辆在正常路况下行驶时，整车控制器可自动将车辆动力总成调整为纯电动模式或第一混合动力模式，以提高车辆的行驶速度并降低油耗。在车辆需要以较大的动力行驶时，整车控制器可将车辆动力总成调整为第二混合动力模式，发动机3、第一电机4和第二电机5共同驱动车辆，使车辆获得更大的加速度，满足驾驶需要。
需要说明的是，上述的“主动轮”相当于输入齿轮，“从动轮”相当于输出齿轮，“一档主动轮”相当于三级输入齿轮，“一档从动轮”相当于三级输出齿轮，“二档主动轮”相当于四级输入齿轮，“二档从动轮”相当于四级输出齿轮，“三档主动轮”相当于一级输入齿轮，“三档从动轮”相当于一级输出齿轮，“四档主动轮”相当于二级输入齿轮，“四档从动轮”相当于二级输出齿轮，“三档齿轮组”相当于一级齿轮组，“四档齿轮组”相当于二级齿轮组，“一档齿轮组”相当于三级齿轮组，“二档齿轮组”相当于四级齿轮组，“第一输出轴”相当于前输出轴，“第二输出轴”相当于后输出轴，“中间轴”相当于输出轴。
综上，本申请实施例提供的车辆混合动力总成，无需将电机结合到现有的变速箱中，具有更简单的结构，占用了更小的空间，降低了整车设计的难度。本申请实施例提供的车辆混合动力总成控制方法，可以将车辆混合动力总成配 置为发动机模式、纯电动模式、第一混合动力模式或第二混合动力模式，并能够根据车辆行驶情况或驾驶员的需要调整为相应的驾驶模式，节约电能，降低油耗，增加车辆的续航里程，为驾驶员带来更好的驾驶体验。在发动机模式下，车辆动力总成能够通过发动机3输出相对较大的扭矩，满足车辆起步或爬坡时动力需求，同时第一电机4和第二电机5不工作，避免了电机因负载过大而温度过高，提高车辆的性能和电机的使用寿命。在发动机模式、纯电动模式、第一混合动力模式或第二混合动力模式下，整车控制器均可控制第二离合器62接合，车辆的后传动轴12，实现四轮驱动，使车辆获得更大的动力，以满足不同情况下的驾驶需求。
在本申请中，术语“第一”和“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。术语“多个”指两个或两个以上，除非另有明确的限定。
以上所述，并非对本发明作任何形式上的限制，虽然本发明已通过实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
