车辆驱动装置的控制装置及插电式混合动力车辆
技术领域
本发明涉及一种混合动力车辆驱动装置的控制装置以及设有该控制装置的插电式(plug-in)混合动力车辆。更具体地，本发明涉及一种安装在具有由发动机输出轴驱动的油泵的混合动力车辆中的车辆驱动装置的控制装置，以及设有该控制装置的插电式混合动力车辆。
背景技术
如例如在专利文献1和2中公开的，混合动力车辆中设置的普通驱动装置包括诸如汽油发动机或柴油发动机的发动机以及诸如马达或马达/发电机的电动机。发动机和电动机以各种形式相结合，并且所使用的电动机的数量并不局限于一个；有时使用多个电动机。
专利文献1和2公开了使用两个电动机的混合动力车辆。在这些混合动力车辆中，发动机、第一马达/发电机和第二马达/发电机经由由行星齿轮机构构成的动力分配机构相互连接。该行星齿轮机构的齿圈的动力经由动力传递机构传递到驱动轮。因而，发动机和第二马达/发电机中的一个或两者的动力能够被输出到驱动轮。
在这种混合动力车辆中，通过基于各种条件控制发动机及马达/发电机的驱动和停止，可通过发动机行驶、EV行驶或者发动机/马达行驶来实现行驶，该发动机行驶是通过仅驱动发动机实现行驶的行驶模式，该EV行驶是通过仅驱动马达/发电机而不驱动发动机实现行驶的行驶模式，该发动机/马达行驶是通过驱动发动机和马达/发电机两者实现行驶的行驶模式。这些行驶模式之间的切换可自动执行，或者通过驾驶员的手动操作进行。
当从EV行驶切换到发动机/马达行驶时，由发动机启动控制装置执行停止的发动机的启动。此时，发动机启动控制装置通过向联接到发动机的第一马达/发电机供电来执行起转(cranking)。当发动机达到预定转数时，执行燃料喷射和点火以开始发动机的运转。
在混合动力车辆中，在行驶期间发动机的启动/停止反复进行。因此，为了确保驾乘舒适性，寻求平滑的发动机启动。为了实现平滑的发动机启动，在通过起转使发动机转数升高至接近自持运转的转数之后，执行燃料喷射和点火。此时，发动机转矩波动——特别是由发动机的初始点火导致的转矩波动——作为扭转振动经由曲轴被传递到各种动力传递机构例如由行星齿轮机构构成的动力分配机构。为了吸收此振动，在曲轴与输入轴之间设置吸收振动的阻尼器。此外，为了吸收不能被阻尼器吸收的传递到动力分配机构的振动，执行使得能够在从发动机到驱动轮的动力传递路径中进行动力传递的电动机(例如在专利文献1和2中公开的混合动力车辆中，第二马达/发电机对应于此电动机)的转矩控制，从而吸收已到达动力分配机构的振动。即，经由发动机控制装置和电动机控制装置控制发动机和电动机的驱动的混合动力控制用控制器执行如下的控制：由上述电动机的旋转位置信息、发动机转数信息、预编程的各部件的扭转刚度、惯性矩、滞后值等等计算最优的校正转矩值，并且校正所述电动机的转矩以使之增大或减小。因而，即使是已到达动力分配机构的由发动机初始点火等导致的较大的振动也被减小。结果，从动力分配机构传递到下游侧的差速器、驱动轴、车身等的振动也减小，从而可提高驾驶员的驾乘舒适性。
顺便提及，在混合动力车辆中常常设置有油润滑机构，其中通过发动机输出轴的旋转而使油泵工作，以将润滑油从该油泵供给到动力分配机构等。在EV行驶期间，发动机和油泵都停止，从而在EV行驶期间这种油润滑机构停止向动力分配机构供给润滑油。当这种状态持续长时间时，存在由于动力分配机构内的润滑不充分而导致发生热损害的危险。
因此，在专利文献2中公开的混合动力车辆中，在EV行驶期间，第一马达/发电机的旋转转矩在预定的定时被传递到用于使油泵工作的旋转轴，从而油泵***作预定的一段时间以将润滑油供给到动力分配机构等。通过此构造，即使在混合动力车辆的EV行驶期间，也在适当的定时在必要的时间段期间向动力分配机构供给润滑油，从而防止对在油泵的工作停止时润滑油的供给被停止的部位的热损害。

发明内容
发明要解决的问题
顺便提及，如果在EV行驶期间，发动机被强制启动且油泵工作一定的时间段，则解决了对通过油泵供给润滑油的部位的热损害以及发动机的滑动阻力的问题。但是，当在车辆处于高速度范围的EV行驶期间启动发动机时，难以使用用于在从发动机到驱动轮的动力传递路径中进行动力传递的电动机的转矩控制来吸收从发动机传递的转矩波动(扭转振动)。其原因在于，当在高速度范围中行驶时，电动机的转数高，从而增加或减小电动机转矩的校正可能从最优定时延迟，结果不能充分吸收上述振动。因此，被传递到在动力分配机构下游侧的差速器、驱动轴、车身等的振动不能被减小，从而驾乘舒适性变差。
另外，还存在如下的可能性，即，由于增加或减小电动机转矩的校正从最优定时延迟，因此电动机和发动机的旋转同步将出现偏移，从而在动力分配机构内的齿轮元件之间出现磨齿噪声。
鉴于这些问题提出了本发明，并且本发明的一个目的是在具有与发动机输出轴的旋转相连动地操作的油泵并且具有EV行驶作为行驶模式的插电式混合动力车辆中提供一种车辆驱动装置的控制装置，并且还提供一种具有该控制装置的插电式混合动力车辆，该控制装置通过在EV行驶期间在合适的定时启动发动机，增加抑制由发动机的转矩波动造成的振动和噪声的频度，除此之外还可在尽可能地确保由EV行驶实现的连续行驶距离的同时防止对通过油泵供给润滑油的部位的热损害。
解决问题的手段
作为解决上述问题的一种手段，本发明的车辆驱动装置的控制装置被以如下方式配置。即，本发明提供了一种车辆驱动装置的控制装置，所述车辆驱动装置具有用于将电动机的动力传递至驱动轮的动力传递装置和连接到所述动力传递装置的发动机，可实现EV行驶，所述EV行驶是在不驱动所述发动机的状态下仅利用所述电动机进行行驶的行驶模式，所述控制装置具有：存储装置，所述存储装置存储已根据车速被设定的车速影响值、所述车速影响值的和值的第一阈值、所述车速影响值的和值的低于所述第一阈值的第二阈值以及发动机启动基准车速；求和装置，当车辆的行驶模式为EV行驶时，所述求和装置对与所述车辆的车速对应的所述车速影响值进行逐时刻求和；发动机启动判断装置，所述发动机启动判断装置判断在EV行驶期间所述发动机的启动是否有必要；发动机启动装置，当所述发动机启动判断装置已判断出所述发动机的启动有必要时，所述发动机启动装置启动所述发动机；以及车速检测装置，所述车速检测装置检测车速。在由所述求和装置求和得出的和值不小于所述第一阈值的情况下，以及在由所述求和装置求和得出的和值不小于所述第二阈值并且由所述车速检测装置检测出的车速不大于所述发动机启动基准车速的情况下，所述发动机启动判断装置判断为有必要启动所述发动机，而在其他情况下所述发动机启动判断装置判断为不必启动所述发动机。
另外，由所述求和装置进行的对与所述车辆的车速对应的所述车速影响值的逐时刻求和可以是对与所述车辆的车速对应的所述车速影响值按固定时间间隔进行的求和。这里，车速可以是在固定时间间隔每次出现时的瞬时车速，或者在固定时间间隔每次出现时的平均车速。
当上述的车辆驱动装置的控制装置被安装在具有与发动机输出轴相连动地操作的油泵的混合动力车辆中时，当在EV行驶期间车速影响值的和值不小于第一阈值时，通过发动机启动判断装置和发动机启动装置，停止的发动机被启动，并且润滑油通过油泵被供给。因此，通过在考虑由油泵供给润滑油的部位的无润滑容许量的情况下设定与车速对应的车速影响值及第一阈值，可以在尽可能地确保利用EV行驶实现的连续行驶距离的同时防止对那些部位的热损害。另外，由于通过启动发动机来使油泵工作，因此不会发生由于发动机的滑动阻力引起的能量损失——而传统的混合动力车辆中可能发生这种情况。
此外，当在EV行驶期间车速影响值的和值不小于第二阈值，并且车速不大于发动机启动基准车速时，通过发动机启动判断装置和发动机启动装置，停止的发动机被启动，并且润滑油通过油泵被供给。因此，通过将发动机启动基准车速设定为略低，可以将启动发动机时的电动机转数抑制在低水平。例如，当上述的车辆驱动装置的控制装置被安装在执行在电动机侧吸收发动机转矩波动的控制的混合动力车辆中时，当在EV行驶期间启动发动机时电动机的转数低，从而在上述控制中不太可能发生延迟响应，并且易于充分吸收由于发动机的初始点火导致的甚至较大的转矩波动。另外，由于这种延迟响应不太可能发生，所以也不可能发生电动机和发动机的旋转同步偏移，从而几乎不可能在动力传递装置例如动力分配机构内的齿轮元件之间出现磨齿噪声。
此外，在本发明的车辆驱动装置的控制装置中，在上述构型中，希望所述车速影响值被设定成在高速时比在低速时高。在一般的大齿轮元件、齿轮元件等中，随着车速增加即随着转数增加，无润滑油供给的容许时间变短。因此，根据本发明，可在更合适的定时使油泵工作。
本发明的插电式混合动力车辆具有上述车辆驱动装置的控制装置中的任一个；以及用于接收来自家用电源的电力供应并且为所述电动机的电池充电的充电装置。
此插电式混合动力车辆可通过接收来自合适的家用电源的电力供应仅利用EV行驶来连续行驶，从而当驾驶员主动选择EV行驶时，能够获得上述车辆驱动装置的控制装置的作用效果的机会增大。
发明的效果
通过将本发明应用于具有与发动机输出轴的旋转相连动地操作的油泵并且具有EV行驶作为行驶模式的混合动力车辆中，可以通过在合适的定时启动发动机，来增加抑制由发动机的转矩波动造成的振动和噪声的频度，除此之外还可以在尽可能地确保利用EV行驶实现的连续行驶距离的同时防止对通过油泵供给润滑油的部位的热损害。

具体实施方式
以下将参照附图描述根据本发明一实施例的车辆驱动装置的控制装置和具有该控制装置的插电式混合动力车辆。在本发明的此实施例中，作为示例，描述具有两个马达/发电机(电动机)并且被构造成FF(前置发动机前轮驱动)车辆的插电式混合动力车辆。根据本发明的此实施例的车辆驱动装置的控制装置主要具有如下文所述的ECU 31、马达控制器32、混合动力控制用控制器33等等。插电式混合动力车辆配备有用于给马达/发电机电池充电的充电装置，并且具有也可从家用电源充电的功能。下文中，插电式混合动力车辆被简称为混合动力车辆。
图1包括示意性地示出混合动力车辆的变速驱动桥1等的动力***的原理图。图2是详细示出图1中的变速驱动桥1的构造的横截面图。
如图1所示，混合动力车辆的变速驱动桥1被构造成包括主要用作发电机的马达/发电机MG1(下文还被称为“发电机MG1”)、主要用作电动机的马达/发电机MG2(下文还被称为“马达MG2”)、动力分配机构4、减速机构5以及差速器T4。发动机2经由曲轴2a(发动机2的输出轴等)连接到变速驱动桥1，并且变速驱动桥1用作用于将马达MG2和发动机2的动力传递至驱动轮3的动力传递装置。
动力分配机构4的行星齿轮机构具有太阳齿轮10、小齿轮11、齿圈12和行星架13，太阳齿轮10是在多个齿轮元件的中心自转的外部有齿的齿轮，小齿轮11是在与太阳齿轮10外部接触时在太阳齿轮10附近自转同时公转的外部有齿的齿轮，齿圈12是形成为空心环以便与小齿轮11啮合的内部有齿的齿轮，行星架13轴颈支承小齿轮11并且经由小齿轮11的公转而自转。动力分配机构4经由副轴主动齿轮T1、副轴从动齿轮T2、最终齿圈T3和差速器T4将从发动机2和马达MG2中的至少一个输出的动力传递给驱动轮3。
减速机构5的行星齿轮机构具有太阳齿轮10A、小齿轮11A和齿圈12A，太阳齿轮10A是在多个齿轮元件的中心自转的外部有齿的齿轮，小齿轮11A是被齿轮架C(变速驱动桥壳体)轴向支承的在与太阳齿轮10A外部接触时自转的外部有齿的齿轮，齿圈12A是形成为空心环以便与小齿轮11A啮合的内部有齿的齿轮。动力分配机构4的齿圈12、减速机构5的齿圈12A以及副轴主动齿轮T1结合成一体。减速机构5以适当的减速比减小从发动机2和马达MG2中的至少一个输出的动力，并且经由副轴主动齿轮T1、副轴从动齿轮T2、最终齿圈T3和差速器T4将减小后的动力传递给驱动轮3。
差速器T4是双小齿轮类型的差速器，并且通过必要时将从最终齿圈T3输入的动力分配给左侧和右侧车轮3来传递该动力。
通过驱动发动机2而产生的旋转转矩经由曲轴2a和螺旋弹簧式变速驱动桥阻尼器14传递到输入轴16。油泵20经由中空轴17设置在输入轴16的轴线上，并且油泵20通过接收输入轴16的旋转转矩的供给而工作。余摆线型泵、齿轮状泵等可用作油泵20。油盘21充满润滑油，并且被油泵20抽吸出的润滑油被传递至诸如动力分配机构4的各个部位的动力***(动力传递装置)，然后在各个齿轮元件以及各个轴的旋转部和滑动部之中循环，从而润滑油起到冷却各个部位、减小摩擦阻力、防止腐蚀并且保持气密性的作用。
例如，在图2以及作为图2的部分放大视图的图2-1的示例中所示的变速驱动桥1中，为使油泵20工作而被旋转的中空轴17(用于使油泵20工作的旋转轴)花键配合到输入轴16，从而与输入轴16作为一体旋转。油泵20由于输入轴16和中空轴17与发动机2的曲轴2a一起旋转而工作。工作的油泵20抽吸出油盘21的润滑油，并且经由中空轴17以及在输入轴16中形成的中空部16a和喷射孔16b，将该润滑油传递到诸如动力分配机构4的各个部位的动力***。
关于动力分配机构4和减速机构5的各齿轮元件的连接构造，行星架13连接到输入轴16以与之形成一体，太阳齿轮10连接到下文所述的转子MG1R以与之形成一体，并且太阳齿轮10A连接到下文所述的转子MG2R以与之形成一体。
发电机MG1是交流同步发电机，其具有由可旋转地被输入轴16支承的永磁体构成的转子MG1R，和缠绕有三相绕组的定子MG1S。发电机MG1提供用于发电机MG1和马达MG2的电池7(下文，简称为“电池7”)的充电以及用于马达MG2的驱动的电力，并且通过控制发电量来改变转子MG1R的转数，从而实现变速驱动桥1的无级变速器功能。同样，马达MG2是交流同步发电机，其具有由可旋转地被中空轴17支承的永磁体构成的转子MG2R，和缠绕有三相绕组的定子MG2S。通过向三相绕组供给三相交流电，在马达内产生旋转磁场，从而输出预定的旋转转矩。马达MG2用作发动机2的辅助动力源，并且除了辅助平滑车辆启动和加速外，当执行再生制动操作时将车辆的运动能转换成电能，并为电池7充电。电池7具有的结构可以为单独的各电池模块适当地串联连接，以便提供必要的额定电压。
具有家用电源插头18的充电回路(充电装置)19连接到电池7。充电回路19经由家用电源插头18从家用电源接收电力供应，并为电池7充电。
作为控制上述动力***的***控制器，准备了以下部件：发动机电子控制单元(ECU)31，其基于未示出的曲柄位置传感器、凸轮位置传感器、节气门位置传感器等的各种传感器输出执行发动机2的燃料喷射控制、点火正时控制、可变气门正时控制等；车速传感器(车速检测装置)35；混合动力控制用控制器33，其基于车速传感器35、未示出的加速器开度传感器和档位传感器等的输出获得必要的发动机2的输出以及马达MG2以及发电机MG1的转矩，将要求值输出到ECU 31和下面的马达控制器32，并且执行动力***的控制；以及马达控制器32，其根据来自控制器33的驱动要求值经由逆变器6控制发电机MG1和马达MG2。
顺便提及，当在高输出下进行长距离行驶，并且发动机2上具有一定量的负荷时，发动机2的发动机效率良好，但是当发动机2上存在小负荷时例如当低速行驶时，发动机效率差。另一方面，马达MG2具有大的低速转矩，因此适合于车辆启动或者低速行驶为普遍情况的市内驾驶，但是马达MG2的行驶距离短。在混合动力车辆中，这些特性被用于根据行驶环境不同地灵巧地使用发动机2和马达MG2，并且通过在补偿发动机2和马达MG2的弱点的同时良好地使用它们各自的优点，实现了平滑的和反应迅速的动力性能，并且改进了燃料消耗。
例如，在车辆启动或者低速行驶期间，发动机2停止，并且从电池7接收到电力供应以通过仅驱动马达MG2来行驶(在本说明书中还被称为“EV行驶”)。因此，混合控制器33操作设置在电池7中的中继器34以向逆变器6提供直流高电压电力。用于马达MG2和发电机MG1中的各个的由六个功率晶体管构成的三相桥接电路设置在逆变器6中，并且在直流电和三相交流电之间切换。功率晶体管的控制由马达控制器32执行，并且电流控制所必需的信息例如输出电流值被从逆变器6发送至马达控制器32。逆变器6调节三相交流电的幅值和频率以便将马达MG2的输出转矩和转数调节至所希望的值，并且将它们供给到马达MG2。
应指出，当车辆开始移动时或者当低速行驶时，EV行驶由混合动力控制用控制器33自动设定，但是混合动力控制用控制器33还可通过接收驾驶员的预定手动操作强行设定EV行驶，而不管混合动力车辆的行驶状态如何。
在通常行驶期间，通过驱动发动机2，发动机2的输出的一部分被传递至驱动轮3，并且通过使用剩余的部分来发电，发动机MG1获得的电力被用于驱动马达MG2(在本说明书中还被称为“通常HV行驶”)。在通常HV行驶期间，动力分配机构4中的动力分配被调整为使得发动机2在高转矩范围内以良好的燃料消耗率工作，从而辅助发动机2的输出。混合动力控制用控制器33由加速器踏板被下压的量和车速计算必要的发动机输出，并且从最优的燃料效率线计算发动机转数。此外，混合动力控制用控制器33通过执行电子节气门开度控制，并且从动力分配机构4的共线特性获得发电机MG1的转速，来控制发动机转数。同时，混合动力控制用控制器33由驱动轮3的必需的驱动力计算应当由马达MG2分担的转矩，并且向马达控制器32输出必要的要求值。
在高负荷行驶期间，例如当在以全开加速度行驶时或者当在爬坡时，除了上述通常行驶期间的驱动方法外，还存在这样的行驶，即从电池7接收电力供应以驱动马达MG2，并且增加马达MG2的输出转矩以辅助发动机2的输出(在此说明书中还被称为“高负荷HV行驶”)。可通过调整供给马达MG2的三相交流电的电流值来调节马达MG2的输出转矩。
在通常HV行驶或者高负荷HV行驶期间，车辆在发动机2运转的状态下行驶，从而油泵20通过发动机2的输出而工作。另一方面，在EV行驶期间，车辆在发动机2停止的状态下行驶，从而在EV行驶时不能使用发动机2的输出来使油泵20工作。当油泵20停止，并且润滑油没有被供给到诸如动力分配机构4的动力***的状态持续一定的一段时间时，会发生轴承、齿轮等的烧损和磨损，因此在此实施例中，执行强制启动发动机2的控制。
如图1所示，在混合动力控制用控制器33的存储器中设置寄存器41，在该寄存器41中与车辆的行驶模式相对应地设定标记。当车辆的行驶模式转换到EV行驶时，混合动力控制用控制器33的CPU在寄存器41中设定标记‘1’，并且当车辆的行驶模式转换到除EV行驶外的行驶模式(例如，通常HV行驶或高负荷HV行驶)时，混合动力控制用控制器33的CPU在寄存器41中设定标记‘0’。此外，第一图谱42和第二图谱43被存储在混合动力控制用控制器33的存储器中。另外，油温传感器44设置在动力分配机构4中，并且混合动力控制用控制器33被构造成能够检测动力分配机构4内的油温。
如图3所示，在第一图谱42中设定对应于车速的车速影响值。车速影响值被设定成在高速时比在低速时高。当车辆的行驶模式为EV行驶时，混合动力控制用控制器33对与车辆的车速相对应的车速影响值进行逐时刻求和。在此实施例中，混合动力控制用控制器33以固定的时间间隔(1分钟)计算平均车速，并且依次对在第一图谱42中已对应于此平均车速被设定的车速影响值进行求和。
如图4所示，在第二图谱43中设定EV连续行驶界线43a、发动机启动等待线43b以及发动机启动基准车速线43c。EV连续行驶界线43a是上述车速影响值的和值的阈值(第一阈值)。它是当可在油泵20不工作的情况下行驶时的车速影响值的和值，并且是通过实验、仿真等预先获得的值。此EV连续行驶界线43a优选地相对于上述获得值具有一些余量，从而可进行安全行驶而不会对由于油泵20停止而没有被供给润滑油的部位(例如，动力分配机构4等的齿轮元件10、11等)造成热损害。车辆启动等待线43b是上述车速影响值的和值的阈值(第二阈值)，并且被设定成小于第一阈值。例如，第二阈值被设定在第一阈值的50％-90％的范围内。发动机启动基准车速线43c是用作用于在上述车速影响值的和值已变得不小于第二阈值之后判断是否有必要启动发动机2的基准的车速。发动机启动基准车速线43c希望地是这样的车速，即在该车速下当在混合动力车辆进行EV行驶的情况下启动发动机时，可通过马达MG2的转矩控制来充分吸收从发动机传递至动力分配机构4的转矩波动。就是说，发动机启动基准车速线43c希望地是这样的车速，即在该车速下在马达MG2的转矩控制中几乎没有发生延迟响应。
图5是示出在车辆行驶模式为EV行驶时，当混合动力控制用控制器33等启动发动机2并且使油泵20工作时的处理过程的流程图。
在步骤ST1中，混合动力控制用控制器33监视寄存器41中设定的标记，并且执行车辆的行驶模式是否已变换到EV行驶的检查。
在混合动力车辆中，执行***设计，使得当基于车辆行驶状况(例如车速、加速器开度、制动和变速位置)满足预定发动机停止条件时，发动机自动停止。因此，当满足发动机停止条件时，在寄存器41中设定‘1’。作为发动机停止条件，可设定诸如下列条件的条件：(1)自车辆开始移动以来还未达到预定的车速；(2)在一定的时间段中车速持续未超过预定车速；(3)从车速和制动操作信息判断为车辆处于减速或制动的状态；或(4)通过驾驶员的手动操作已将EV行驶选作车辆的行驶模式。
当在发动机2运转的状态下发动机停止条件成立时，混合动力控制用控制器33向ECU 31输出发动机停止请求信号以停止发动机2。当检测到寄存器41中设定‘1’时(步骤ST1；是)，混合动力控制用控制器33逐时刻地对基于从车速传感器35的输出获得的车速已在第一图谱42中设定的车速影响值进行求和(步骤ST2)。在此实施例中，混合动力控制用控制器33每隔一分钟计算平均车速，并且还基于第一图谱42计算对应于该平均车速的车速影响值，并依次对计算出的车速影响值求和。执行求和的时间间隔并不局限于上述时间间隔。此外，作为平均车速的替代，混合动力控制用控制器33可每隔预定的时间间隔计算瞬时车速，继而从第一图谱42获得对应于该瞬时车速的车速影响值，并且对那些车速影响值进行求和。
在步骤ST3中，混合动力控制用控制器33判断车速影响值的和值是否至少高达在第二图谱43中设定的发动机启动等待线43b(第二阈值)。
当步骤ST3中的判断结果为肯定时，在步骤ST4中，混合动力控制用控制器33判断车速是否不高于发动机启动基准车速线43c。另一方面，当步骤ST3中的判断结果为否定时，此例程被暂时省略。
当步骤ST4中的判断结果为肯定时，在步骤ST5中，混合动力控制用控制器33从油温计44的输出信号测量动力分配机构4内的油温，然后处理过程前进到步骤ST6。
在步骤ST6中，混合动力控制用控制器33经由ECU 31启动发动机2，根据在ST5中测量的动力分配机构4内的油温设定运转时间，并且使发动机2运转该设定的运转时间(一定时间)。即，由于在上述ST3中作出肯定判断并且在上述ST4中也作出肯定判断，混合动力控制用控制器33判断为发动机启动是必需的，并启动发动机2。当车速低于发动机启动基准车速线43c时，执行发动机2的启动。因此，马达MG2的转数也比较低，从而可通过马达MG2的转矩控制来充分吸收在启动发动机时从发动机2传递的转矩波动(扭转振动)、尤其是由于发动机2的初始点火导致的较大的转矩波动，并且也可抑制动力分配机构4、减速机构5等的齿轮元件的磨齿噪声。应指出，马达MG2的上述转矩控制是公知且惯用的技术，因此在此不再描述。
在发动机2的运转期间，曲轴2a的旋转动力经由螺旋弹簧式变速驱动桥阻尼器14、输入轴16、中空轴17等使油泵20工作，从而通过油泵20执行动力分配机构4内的油润滑。发动机2的运转时间(设定运转时间)是润滑所必需的时间。例如，在混合动力控制用控制器33中，使油泵20工作的泵工作转数以及与泵工作时间有关的信息被预先存储在存储器中，作为与动力分配机构4内的油温相关联的表信息。混合动力控制用控制器33根据上述油温设定发动机2的运转时间和转数。
另一方面，当步骤ST4中的判断结果为否定时，在步骤ST7中，混合动力控制用控制器33判断车速影响值的和值是否至少高达在第二图谱43中设定的EV连续行驶界线43a。
当步骤ST7中的判断结果为肯定时，处理过程移动到步骤ST5。即，由于在步骤ST7中作出肯定判断，混合动力控制用控制器33判断为发动机启动是必需的，并且启动发动机2。另一方面，当步骤ST7中的判断结果为否定时，此例程被暂时省略。
在步骤ST6中启动发动机之后，在步骤ST8中，混合动力控制用控制器33清除车速影响值的和值以使之恢复为0值，并且此例程被暂时省略。应指出，当发动机2启动时，在寄存器41中设定标记‘0’，从而在发动机2的运转期间，在步骤ST1中作出否定判断，并且从步骤ST2以后的过程没有被执行。另一方面，当经过了上述设定运转时间时，发动机2的运转停止，并且车辆的行驶模式再次变为EV行驶，在寄存器41中设定标记‘1’，并且从步骤ST2以后的过程被执行。
根据上述混合动力车辆，当车辆在润滑油没有被供给到动力分配机构4的状态下行驶一段时间，并且车速影响值的和值至少高达EV连续行驶界线43a，或者车速影响值的和值至少高达发动机启动等待线43b并且车速不高于发动机启动基准车速线43c时，发动机2启动，并且与发动机相连动地操作的油泵20工作以将润滑油供给到动力分配机构4。因此，可防止动力分配机构4内的烧损。此外，由于油泵20因发动机2的运转而工作，所以不会发生由于发动机的滑动阻力造成的动力损失。
以下将说明两个具体示例，其中在安装有车辆驱动装置控制装置的上述混合动力车辆在EV行驶模式下行驶时执行上述处理过程。
将参照图6描述第一示例。在图6中，横轴指示行驶时间，纵轴指示平均车速或车辆影响值的和值。在此示例中，混合动力车辆已从停止状态转换到EV行驶模式并已开始行驶。当行驶模式转换到EV行驶模式时，在寄存器41中设定‘1’，从而混合动力控制用控制器33检测到在寄存器41中设定‘1’(步骤ST1：是)，并且逐时刻地对与车速相对应的车速影响值进行求和(步骤ST2)。
首先，当自开始对车速影响值进行求和以来已经过了一分钟时，混合动力控制用控制器33计算一分钟期间的平均车速。这里，平均车速为10km/h，并且基于第一图谱42计算对应于此平均车速的车速影响值。在第一图谱42中，1被设定为与平均车速10km/h相关联的车速影响值，从而在这里，计算出的车速影响值为1，并且执行将1与初始值0相加的求和处理。
此后，从开始求和直到已经过了12分钟，在图6的示例中，对于每一分钟的平均时速和车速影响值依次为(20km/h，2)，(10km/h，1)，(40km/h，3)，(50km/h，3)，(60km/h，5)，(60km/h，5)，(60km/h，5)，(70km/h，5)，(100km/h，6)，(100km/h，6)，(100km/h，6)，从而车速影响值的和值变为48。在此期间，步骤ST1到ST3的处理被重复执行。这里，括号中的第一个数字指示平均车速，第二个数字指示对应于该车速在第一图谱42中设定的车速影响值。下文同样如此。
此外，在又经过一分钟从而自开始求和以来已经过了13分钟的时间点，车速影响值的和值变为54，因此不小于在第二图谱43中设定的发动机启动等待线43b的值50(步骤ST3：是)。
此后，对于每分钟的平均时速和车速影响值依次为(80km/h，5)，(70km/h，5)和(60km/h，5)，并且在自开始对车速影响值求和以来已经过了16分钟的时间点，车速影响值的和值变为69。在此期间，车速总是大于发动机启动基准车速线43c的值40km/h，并且车速影响值的和值总是小于EV连续行驶界线43a的值80，从而步骤ST1到ST4以及步骤ST7的处理被重复执行。
此外，在又经过一分钟从而自开始对车速影响值求和以来已经过了17分钟的时间点，车速变为40km/h，其不大于发动机启动基准车速线43c的值(步骤ST4：是)，因此在测量油温之后(步骤ST5)，启动发动机2(步骤ST6)，并且清除车速影响值的和值(步骤ST8)。发动机2运转设定的时间，从而与发动机2相连动地操作的油泵20工作，由此执行动力分配机构4内等的油润滑。
在发动机2的运转期间，在寄存器41中设定标记‘0’，从而在步骤ST1中作出否定判断，并且不执行步骤ST2中的行驶计数。此后，当发动机2停止因此行驶模式再次变为EV行驶时，在寄存器41中设定标记‘1’，从而在步骤ST1中作出肯定判断，并且再次执行从步骤ST2以后的处理过程。
将参照图7描述第二示例。在图7中，同样地，横轴指示行驶时间，纵轴指示平均车速或车速影响值的和值。在此示例中，混合动力车辆在从停止状态转换到EV行驶之后开始行驶。当行驶模式转换到EV行驶时，在寄存器41中设定‘1’，从而混合动力控制用控制器33检测到在寄存器41中设定‘1’(步骤ST1：是)，并且逐时刻地对与车速相对应的车速影响值进行求和(步骤ST2)。直到自开始对车速影响值进行求和以来已经过了16分钟的时间点，此示例与参照图6所描述的示例相同，从而这里将省略对其的描述。
从自开始对车速影响值进行求和以来已经过了16分钟的时间点起，当对于每分钟的平均时速和车速影响值依次为(70km/h，5)和(70km/h，5)时，在自开始对车速影响值进行求和以来已经过了18分钟的时间点，车速影响值的和值变为79。在此期间，步骤ST1-ST4以及步骤ST7：否的处理被重复执行。
此外，在又经过一分钟从而自开始对车速影响值进行求和以来已经过了19分钟时，车速影响值的和值变为84，因此不小于在第二图谱43中设定的EV行驶界线43a的值80(步骤ST7：是)，并且在测量油温之后(步骤ST5)，启动发动机2(步骤ST6)，且清除车速影响值的和值(步骤ST8)。发动机2运转设定的时间，并且如前文所述地，执行油润滑。而且，如前文所述，在发动机2的运转期间，在寄存器41中设定标记‘0’，从而在步骤ST1中作出否定判断，并且不执行步骤ST2中的行驶计数。此后，当发动机2停止从而行驶模式再次变为EV行驶时，在寄存器41中设定标记‘1’，因此在步骤ST1中作出肯定判断，并且再次执行从步骤ST2向前的处理过程。
上文中，作为示例，描述了具有两个电动机的混合动力车辆，但是，本发明还可应用于仅具有一个电动机的混合动力车辆。例如，本发明还可应用于具有如下构造的混合动力车辆：发动机、一个电动机和变速器依所述次序串联连接；发动机和电动机之间的连接经由离合器被切断或建立；并且油泵与相对于离合器处于发动机侧的旋转相连动地操作。在这种混合动力车辆中，通过释放离合器，可将行驶模式设定为EV行驶，并且通过例如接合离合器以启动发动机，可通过油泵供给润滑油。
在这种混合动力车辆中，同样，当在高速下在EV行驶期间启动发动机时，难以利用电动机的转矩控制吸收从发动机传递的转矩波动(扭转振动)。但是，如果应用本发明，则当车速影响值的和值不小于EV连续行驶界线的值时，或者当车速影响值的和值不小于发动机启动等待线的值并且车速不高于发动机启动基准车速线的值时，发动机启动，并且与发动机相连动地操作的油泵工作，从而易于利用电动机的转矩控制吸收当启动发动机时从发动机传递的转矩波动。另外，可防止在预定的部位发生烧损。
此外，如上所述，在此实施例中，本发明应用于插电式混合动力车辆，但是本发明并不局限于此；只要混合动力车辆具有EV行驶作为行驶模式就足够了，并且混合动力车辆可以是不包括用于为马达/发电机电池充电的充电装置的车辆。
本发明可以在不背离本发明的精神或本质特征的情况下以各种其他形式实施。此申请中公开的实施例在所有方面应被认为是示例性的而不是限制性的。本发明的范围由所附权利要求而不是由前述描述限定，并且在权利要求的等同含义和范围中的所有修改或改变应被包含在本发明中。
本申请要求2008年2月7日提交的日本专利申请第2008-027956号的优先权，该日本专利申请的全部内容通过引用被结合在此。
