Description

串联混合动力机动车
技术领域
本公开涉及可在各种行驶模式下行驶的串联混合动力机动车。
背景技术
作为混合动力机动车，已知串联混合动力机动车和并联混合动力机动车。串联混合动力机动车仅在发电时使用发动机，并联混合动力机动车在行驶时也利用发动机的驱动力。
在串联混合动力机动车中，由于不将发动机的驱动力直接用于行驶，所以，与并联混合动力机动车相比，行驶模式被限定。
在专利文献1中示出了：进行发电控制，以使得串联混合动力机动车的2次电池的目标SOC值在高速行驶时与低速行驶时相比成为高值。由此，从即使在连续的高负荷下也确保能行驶的能量这样的观点出发，在高速行驶时也能够得到充分的驱动力。

专利文献1：日本特开2010－143310号公报
在此，高车速高负荷时需要高功率，所以，驱动用电机需要相应地增大。另外，控制大输出的驱动用电机的变换器(inverter)也被大输出化，从而成为成本提高的主要原因。
发明内容
本公开是搭载发动机、第1电动发电机和第2电动发电机的串联混合动力机动车，该串联混合动力机动车具有：接合发动机和第1电动发电机的第1动力传递机构；接合第1电动发电机和车辆驱动轴的第2动力传递机构；离合器，该离合器能切换地接合第1电动发电机与第1动力传递机构和第2动力传递机构的任一方；以及变速器，该变速器切换变速比地接合第2电动发电机和车辆驱动轴。
而且，还具有通过切换离合器和变速器的接合状态来改变行驶模式的控制装置；作为行驶模式，包括：采用第1电动发电机和第2电动发电机的任一方来行驶的EV行驶模式1；采用第1电动发电机和第2电动发电机双方来行驶的EV行驶模式2；用发动机和第1电动发电机发电并由第2电动发电机来行驶的发动机发电模式；以及用第1电动发电机和第2电动发电机的一方或双方来再生的再生模式。
根据本公开，在串联混合动力机动车中，通过采用多个电动发电机来实现各种行驶模式，能够使电动发电机为较低输出。

具体实施方式
以下，基于附图，对本公开的实施方式进行说明。此外，本公开并非限于在此记载的实施方式。
“构成”
图1示出了本实施方式的串联混合动力机动车10的构成。蓄电池12是锂离子电池、镍氢电池等二次电池，是高输出高容量的蓄电池。
第1变换器(INV1)14和第2变换器(INV2)16与蓄电池12电连接。第1变换器14和第2变换器16将来自蓄电池12的直流电力转换成所希望的交流电力。例如，具有在与蓄电池12的正极和负极相连的正负母线之间配置了2个开关元件的3根桥壁，控制6个开关元件的开关而从3个桥壁的中点得到3相输出。另外，通过开关元件的开关的控制，能够将从3个桥壁的中点输入的交流电力转换成直流电力而供给到蓄电池12。
第1电动发电机(MG1)18与第1变换器14电连接。因此，通过第1变换器14的控制，能够驱动第1电动发电机18来输出动力，并能够将第1电动发电机18的发电电力供给到蓄电池12。
作为第1动力传递机构的第1减速器20与第1电动发电机18的驱动轴相连，发动机(EG)22的驱动轴与该第1减速器20相连。因此，通过驱动发动机22，能够经由第1减速器20而驱动第1电动发电机18来发电，能够将发电电力经由第1变换器14而供给到蓄电池12来对蓄电池12充电。此外，也可以断开第1电动发电机18和发动机22的机械连接。
作为第2动力传递机构的第2减速器26经由离合器24而与第1电动发电机18的驱动轴相连。并且，第2减速器26与车辆驱动轴28相连。因此，通过连接离合器24，能够将第1电动发电机18的驱动力经由第2减速器26而传递到车辆驱动轴28。另外，通过将来自车辆驱动轴28的动力传递到第1电动发电机18，能够在第1电动发电机18发电。此外，车轮32经由差速齿轮30而与车辆驱动轴28相连，通过车辆驱动轴28的驱动力而使车轮32旋转，从而串联混合动力机动车(车辆)10行驶。另外，通过利用车轮32的旋转所带来的车辆驱动轴28的动力进行发电，对串联混合动力机动车10进行再生制动。
第2电动发电机(MG2)34与第2变换器16电连接。因此，通过第2变换器16的控制，能够驱动第2电动发电机34来输出动力，并能够将第2电动发电机34的发电电力供给到蓄电池12。
变速器36与第2电动发电机34的驱动轴相连。该变速器36内置离合器36a，能够将变速比切换成减速比A、减速比B这2级。并且，变速器36与车辆驱动轴28相连。因此，通过将离合器36a与减速比A侧或减速比B侧相连，从而能够将第2电动发电机34的驱动力以减速比A或减速比B传递到车辆驱动轴28。另外，通过将来自车辆驱动轴28的动力传递到第2电动发电机34，能够在第2电动发电机34发电，从而能够对车辆进行再生制动。此外，离合器36a也能够设定为切断连接的中立状态。
并且，本实施方式的串联混合动力机动车10具有控制装置38，该控制装置38根据车辆的状况，为了实现各种行驶模式，控制离合器24、变速器36并且控制第1电动发电机18、第2电动发电机34、发动机22的驱动。
这样，在本实施方式中，作为动力源，具有(i)由内燃机和/或燃气轮机等构成的用于发电的发动机22、(ii)主要用发动机输出进行发电的第1电动发电机18、(iii)主要用于车辆的行驶的第2电动发电机34。另外，作为减速装置/变速装置，具有(i)以固定减速比将发动机22和第1电动发电机18接合的第1减速器20、(ii)以固定减速比将第1电动发电机18和车辆驱动轴28接合的第2减速器26、(iii)使将第1电动发电机18的驱动轴与第1减速器20和第2减速器26的某一个接合或者与哪一个都不接合(中立)这3个状态中的1个接合状态成立的离合器24、(iv)使第2电动发电机34的驱动轴以不同的2种以上的变速比与车辆驱动轴接合的变速器36。
在此，第1电动发电机18无法与车辆驱动轴28和发动机22这两者同时接合。另外，变速器36至少具有通常行驶用的减速器(减速比A)和高速行驶用的减速器(减速比B)这2种。
“行驶模式”
控制装置38通过控制动力装置、离合器、变速器的动作来实现各种行驶模式。表1示出了各模式和各种设备的状态。

在此，表1中的离合器24的“N”表示中立。另外，变速器的“减速比A”表示通常行驶用减速器，“减速比B”表示高速行驶用减速器。
＜EV行驶模式1＞
该EV行驶模式1是通常行驶模式，采用第1电动发电机18和第2电动发电机34中的任一个来行驶。
(i)图4：通常时(驱动第1电动发电机18)
离合器24将第1电动发电机18的输出轴经由减速器26而与车辆驱动轴28相连。变速器36不传递动力，所以，设为中立状态。发动机22、第2电动发电机34停止，用来自蓄电池12的电力驱动第1电动发电机18。蓄电池12成为放电状态。
如图4所示，来自蓄电池12的电力经由第1变换器14而被供给到第1电动发电机18，第1电动发电机18的驱动力被传递到车轮32。
(ii)图2：通常时(驱动第2电动发电机34：减速比A)
离合器24将第1电动发电机18的输出轴经由减速器20而与发动机22相连或设为中立状态。变速器36设为减速比大的减速比A，发动机22、第1电动发电机18停止，用来自蓄电池12的电力驱动第2电动发电机34。蓄电池12成为放电状态。
如图2所示，来自蓄电池12的电力经由第2变换器16而被供给到第2电动发电机34，第2电动发电机34的驱动力在变速器36以减速比A变速后被传递到车轮32。
(iii)图3：高速时(驱动第2电动发电机34：减速比B)
在此情况下，基本上与(ii)图2同样，但变速器36被设为比减速比小的减速比B。因此，如图3所示，通过第2电动发电机34的驱动力，可进行更高速的行驶。
在此，图11示出了由变速器36得到的车辆驱动轴28的转矩与车速的关系。将减速比A和减速比B下的车辆驱动轴转矩一致的车速设为V1，
·在车速小于V1的情况下采用减速比A，
·在车速为V1以上的情况下采用减速比B。
由此，与减速比为1个(减速比A或减速比B)的情况相比，可在所有的车速下增大驱动轴转矩，从而能够提高车辆的加速性能。
另外，在该例子中，第2电动发电机34的输出比第1电动发电机18的大。因此，在通常行驶的情况下，将第2电动发电机34用于驱动的情况居多。但是，在较低输出的状态持续的情况等下，与用第2电动发电机34驱动的情况相比，用第1电动发电机18驱动能够以高效率行驶。这样，可以根据哪一个能够进行高效率的行驶，来切换采用第1电动发电机18还是采用第2电动发电机34。
＜EV行驶模式2＞
图5：高速时(驱动第1电动发电机18和第2电动发电机34：减速比B)
在该EV行驶模式2下，采用第1电动发电机18和第2电动发电机34这两者来行驶。在加速要求高、要求输出转矩大的情况下、或在与用1个电动发电机行驶的情况相比能以高效率进行行驶的情况下，采用该模式。
离合器24将第1电动发电机18的驱动轴经由减速器26而与车辆驱动轴28相连。并且，将发动机22停止。另外，将第2电动发电机34的驱动轴经由变速器36而与车辆驱动轴28相连。并且，如图5所示，利用来自蓄电池12的电力来驱动第1电动发电机18、第2电动发电机34，从而利用两电动发电机的动力而使车辆行驶。蓄电池12为了得到需要的驱动力而成为放电状态。
此外，在图5中示出了在变速器36选择了减速比A的状态，但在通常时采用减速比A而在高速时采用减速比B。
＜发动机发电模式＞
图6：(用第1电动发电机18发电、用第2电动发电机34驱动)
在该发动机发电模式下，驱动发动机，在第1电动发电机18发电，用第2电动发电机34行驶。
离合器24将第1电动发电机18的驱动轴经由减速器20而与发动机22相连。驱动发动机22，通过第1电动发电机18进行发电。驱动第2电动发电机34，经由变速器36来驱动车辆驱动轴28。
在第1电动发电机18的发电量比第2电动发电机34所需的电力多的情况下，用剩余量对蓄电池12充电，在第1电动发电机18的发电量比第2电动发电机34所需的电力少的情况下，从蓄电池12放电。
此外，在图6中示出了在变速器36选择了减速比A的状态，但在通常时采用减速比A而在高速时采用减速比B。
＜再生模式＞
在该再生模式下，在车辆减速时进行再生制动，用发电电力对蓄电池12充电。作为发电机，能够利用第1电动发电机18、第2电动发电机34的哪个都行。于是，在采用第1电动发电机18、第2电动发电机34的任一方的情况下，从采用两者的情况中采用能够高效率再生的构成。在再生模式下，发动机22停止。
图7：(用第2电动发电机34再生)
在图7的构成中，将第2电动发电机34用于再生。第1电动发电机18停止，离合器24经由减速器20而与发动机22相连或者设为中立状态。变速器36选择减速比A和B中效率高的一方。因此，来自车轮32的动力经由车辆驱动轴28、变速器36而被输入到第2电动发电机34，第2电动发电机34的发电电力经由第2变换器16而被充电到蓄电池12。
图8：(用第1电动发电机18和第2电动发电机34再生)
在图8的构成中，将第1电动发电机18和第2电动发电机34双方用于再生。离合器24将第1电动发电机18的驱动轴经由减速器26而与车辆驱动轴28相连。变速器36选择减速比A和B中效率高的一方。因此，来自车轮32的动力经由车辆驱动轴28而被输入到变速器36、第2电动发电机34并且被输入到减速器26、第1电动发电机18。因此，来自第1电动发电机18和第2电动发电机34双方的发电电力被充电到蓄电池12。
图9：(用第1电动发电机18再生)
在图9的构成中，将第1电动发电机18用于再生。第2电动发电机34停止。离合器24将第1电动发电机18的驱动轴经由减速器26而与车辆驱动轴28相连。变速器36不进行动力传递，所以，设为中立状态。来自车轮32的动力经由车辆驱动轴28、减速器26而被输入到第1电动发电机18，第1电动发电机18的发电电力经由第1变换器14而被充电到蓄电池12。
图10：(用第2电动发电机34再生、在发动机22驱动下用第1电动发电机18发电)
在图10的构成中，将第2电动发电机34用于再生，并且，驱动发动机22，由离合器24来连接发动机22和第1电动发电机18的驱动轴，从而在第1电动发电机18发电，用得到的发电电力对蓄电池12充电。此外，关于驱动发动机22而在第1电动发电机18发电，与图6的构成同样。另外，在图10中，变速器36采用变速比A，但也可以采用变速比B。
＜其它＞
表1所示的并非所有的行驶模式，还有其它行驶模式。例如，在与EV行驶模式1的通常时同样的连接状态下，通过使正在驱动的第1电动发电机18或第2电动发电机34反向旋转，能够成为后退模式。另外，变速器36也可以不是2级而是3级以上。
＜实施方式的效果＞
在本实施方式中，控制装置38适当切换第1减速器20和第2减速器26、离合器24、变速器36，从而能够实现很多行驶模式。尤其是，通过切换离合器24来将第1电动发电机18的驱动力也用于车辆的驱动力，所以，在高速高负荷时能够利用第1电动发电机18和第2电动发电机34双方的驱动力。因此，能够将第2电动发电机34的输出设定得较小，从而也能够减小其体型。另外，也能使驱动第2电动发电机34所需的第2变换器16低输出化，而达到低成本化。而且，在低负荷时能够利用更高效率的电动发电机(例如第1电动发电机18)的驱动力，所以，也能够提高系统效率，削减电力消耗的提高、蓄电池容量。
