Description
技术领域
本发明涉及用于检测混合动力车辆的性能的混合动力车辆检测系统和方法。更具体而言,本发明涉及能够检测包括用于混合动力车辆的驱动源(电动机)的驱动单元的性能并对性能较差的车辆指明性能较差的原因的混合动力车辆检测系统和方法。
背景技术
近年来,从低污染等观点,使用发动机和电动机作为动力源并在控制发动机和电动机的同时进行行驶的混合动力车辆得到了广泛关注。在这种混合动力车辆中,安装有用于将从电动机和发动机获得的动力经由变速器输出到驱动轴的动力传递单元(变速车轴,transaxle)。例如,在JP2001-164960A中揭示了此技术。
混合动力车辆需要具有高精度的转矩性能以实现平滑的行驶。例如,在JP2004-219354A和JP2005-140668A中揭示了用于检测混合动力车辆的技术。具体而言,JP2004-219354A揭示了用于检测电动机的性能并能够指明故障原因的技术。JP2005-140668A揭示了用于检测包括两个电动机和差动装置的变速车轴的性能并能够指明故障原因的技术。
但是,前述传统混合动力车辆检测技术具有以下问题。具体而言,JP2004-219354A和JP2005-140668A揭示的检测技术涉及单个电动机或单个变速车轴的检测,而不涉及在电动机或变速车轴与逆变器组合的状态下进行的检测。另一方面,当在作为最终产品形式的车辆状态下检测电动机时,不仅在电动机具有缺陷时,而且在逆变器具有缺陷时,均检测到电动机的异常输出性能。在此情况下,根据传统的检测技术,不能区分故障是由电动机自身的异常、驱动电动机的逆变器的故障还是两者的组合所引起。因此,在车辆状态下检测到故障(例如,即将装运之前的总测试时或使用时发生的故障)时,不能指明故障的区域是位于电动机自身还是与逆变器组合的部分中,由此不得不更换整个混合动力系统。
发明内容
本发明要解决的问题
已经作出本发明以解决以上问题,并且本发明的目的是提供一种混合动力车辆检测系统和方法,其能够检测电动机自身的性能,并对性能较差的电动机指明较差的性能是由电动机自身还是逆变器引起。
解决问题的手段
通过在一个或多个独立权利要求中阐述的特征的组合来实现以上目的,并且从属权利要求给出了本发明的其他有利实施方式。
具体而言,本发明的第一方面提供了一种混合动力车辆检测系统,其用于执行混合动力车辆的检测,在所述混合动力车辆中安装了包括第一电动机和第二电动机的驱动单元、包括用于所述第一电动机的第一逆变器电路和用于所述第二电动机的第二逆变器电路的逆变器单元、以及具有输出轴的发动机来作为动力源,使得在所述发动机、所述第一电动机和所述第二电动机之间允许动力传递,其中,所述检测系统包括用于将所述发动机的所述输出轴锁止的锁止机构,所述检测系统被配置成通过执行以下步骤来进行所述检测:由所述锁止机构将所述发动机锁止;在所述第一电动机连接到所述第一逆变器电路并且所述第二电动机连接到所述第二逆变器电路的第一模式下使所述第一和第二电动机运转,以获得在所述第一模式下运转的每个电动机的输出特性;在所述第一电动机连接到所述第二逆变器电路并且所述第二电动机连接到所述第一逆变器电路的第二模式下使所述第一和第二电动机运转,以获得在所述第二模式下运转的每个电动机的输出特性;以及判定每个电动机的输出特性是否正常。
具体而言,本发明的混合动力车辆检测系统是用于检测安装在混合动力车辆上的第一电动机和第二电动机以及驱动电动机的第一逆变器电路和第二逆变器电路中每个的系统。利用此检测系统,如下进行检测。首先,将被置于允许向/从每个电动机传递动力的发动机锁止(锁止步骤)。通过使发动机的输出轴(驱动单元的输入轴)的旋转锁止,仅允许第一和第二电动机运转,由此可靠地将电动机中的一个电动机的转矩传递到另一个电动机。然后,将第一电动机连接到第一逆变器电路(组合A)并同时将第二电动机连接到第二逆变器电路(组合B)。换言之,将驱动单元和逆变器单元置于第一连接模式(即,通常连接模式)下。在此通常连接模式下,使第一电动机和第二电动机运转,并获得在该模式下每个电动机的输出特性(通常连接模式特性获得步骤)。例如,在通过转矩控制使动力源中的一个运转并通过转数控制使动力源中的另一个运转的同时,获得待检测电动机的输出特性(输出转矩、转数、电力消耗等)。此外,将第一电动机连接到第二逆变器电路(组合C)并同时将第二电动机连接到第一逆变器电路(组合D),这处于第二连接模式(即,互换连接模式)下。换言之,逆变器电路与电动机之间的连接关系与通常连接模式下的连接关系互换。在互换连接模式下,使第一电动机和第二电动机运转,并获得在该模式下每个电动机的输出特性(互换连接模式特性获得步骤)。此后,检查四种组合的每种组合下获得的输出特性(故障判定步骤)。基于检测结果的组合,可以指明第一电动机、第二电动机、第一逆变器电路和第二逆变器电路中具有缺陷的一个。具体而言,在电动机输出异常的情况下,如果同一个电动机的输出即使在将逆变器电路互换以连接到该电动机之后仍异常,则可以判定所涉及的电动机具有缺陷。另一方面,即使逆变器电路互换,如果连接到同一个逆变器电路的电动机的输出异常,则可以判定所涉及的逆变器电路具有缺陷。因此,本发明的检测系统允许电动机在驱动单元和逆变器单元的组合下进行检测,由此指明故障或具有缺陷的部分。
在本发明的检测系统中,在待检测的驱动单元和逆变器单元安装在混合动力车辆上的状态下,自动控制发动机和每个电动机的锁止和运转,并进一步将驱动单元的电动机和逆变器单元的逆变器电路互换成不同的连接组合,并测量每个电动机的输出特性。具体而言,在不将任何单元从车辆拆卸的情况下,测量安装在车辆上的每个电动机的输出特性,并指明具有缺陷的部分。因此,不仅在车辆制造期间,而且还在制造结束(初始状态)、使用期间(老化变化)以及故障发生时,可以在每个动力源与其他混合动力单元组合的状态下检测处于最终产品形式(车辆状态)的混合动力车辆中的每个动力源的性能。
此外,优选地,本发明的混合动力车辆检测系统包括将所述驱动单元与所述逆变器单元之间的电连接断开,并通过向所述逆变器单元的每个所述逆变器电路施加检测电压来判定所述逆变器是否正常。具体而言,将驱动单元与变器单元之间的电连接断开,并在以组合方式检测驱动单元和连接到驱动单元的逆变器单元之前,仅检测每个逆变器电路。

具体实施方式
现在将参考附图给出对本发明的优选实施方式的详细说明。在本实施方式中,本发明应用于用于安装有包括两个电动机的变速车轴的混合动力车辆的检测系统。
如图1所示,本实施方式的混合动力车辆100包括蓄电池1、逆变器2、变速车轴3、混合动力系统控制单元(HV系统控制单元)4、发动机5、发动机控制单元6、电动机控制单元7、输出轴8、制动器9、AC电力计10、DC电力计11、用于连接电动机电缆的电磁开关12(此后称为“开关”12)、以及发动机轴锁止机构13。例如,JP2001-164960A中描述了待检测的混合动力车辆的基本系统构造和基本工作的细节。
发动机5是使用汽油作为燃料的公知内燃机,并受到发动机控制单元6的诸如燃料喷射控制、点火控制和进气量调节控制之类的各种驱动控制。发动机控制单元6与HV系统控制单元4进行通信,并根据来自HV系统控制单元4的控制信号来控制发动机5的运转。根据需要,发动机控制单元6将与发动机5的运转状况相关的数据输出到HV系统控制单元4。
变速车轴3具有两个电动机MG1和MG2、动力传递部30、以及差速齿轮38,并且电动机MG1和MG2以及差速齿轮38被置于能够经由动力传递部30将动力传递给彼此。电动机MG1和MG2是用作发电机和电动机的公知同步电动发电机。电动机MG1和MG2经由开关12和逆变器2电耦合到蓄电池1。由电动机控制单元7来控制电动机MG1和MG2以运转。电动机控制单元7可以接收控制电动机MG1和MG2所需的信号,例如,来自用于检测电动机MG1和MG2的每个的转子的旋转位置的旋转位置传感器(未示出)的信号。电动机控制单元7可以将开关控制信号输出到逆变器2。电动机控制单元7被配置为与HV系统控制单元4通信并根据来自HV系统控制单元4的控制信号来控制电动机MG1和MG2。此外,根据需要,电动机控制单元7可以将与电动机MG1和MG2的运转状况相关的数据输出到HV系统控制单元4。
如图2所示,动力传递部30包括作为外齿轮的太阳轮31、与太阳轮31同心布置的作为内齿轮的齿圈32、与太阳轮31和齿圈32啮合的多个小齿轮33、以及保持小齿轮33使得小齿轮33能够自转和公转的行星轮架34。动力传递部30被构造为使用太阳轮31、齿圈32和行星轮架34作为旋转元件来差速运转的行星齿轮机构。在变速车轴3中,发动机5的曲轴51连接到行星轮架34,电动机MG1连接到太阳轮31,并且电动机MG2连接到齿圈32。齿圈32连接到用于取出动力的动力取出齿轮36。动力取出齿轮36经由链带37连接到传动齿轮35。因此在动力取出齿轮36与传动齿轮35之间传递动力。
逆变器2被配置为将蓄电池1的DC电流转换为AC电流,并将得到的AC电流作为电动机电流供应到变速车轴3的电动机MG1和MG2。逆变器2还包括用于电动机MG1的逆变器电路部分(此后,称为“逆变器电路Cmg1”)和用于电动机MG2的逆变器电路部分(此后,称为“逆变器电路Cmg2”),其由电动机控制单元7控制。
开关12被配置为在逆变器2与变速车轴3之间电连接/断开。具体而言,开关12被接通或关断以使逆变器电路Cmg1和Cmg2与电动机MG1和MG2之间的电连接建立或开路(断开)。开关12可以将逆变器电路Cmg1连接到电动机MG1和MG2中的任一个。类似地,开关12可以将逆变器电路Cmg2连接到电动机MG1和MG2中的任一个。这些连接组合或模式由HV系统控制单元4来控制。
HV系统控制单元4连接到发动机控制单元6、电动机控制单元7、蓄电池1和其他单元以向/从这些单元发送/接收各种控制信号。此外,HV系统控制单元4可以接收用于测量蓄电池1与逆变器2之间的DC电流和DC电压的DC电力计11的测量数据和用于测量逆变器2与变速车轴3之间的AC电流和AC电压的AC电力计10的测量数据。HV系统控制单元4不仅具有控制整个车辆系统的工作的功能,而且还具有控制检测操作、性能判定等的检测功能。
例如当在通常驱动状况下的混合动力车辆100中检测到某些异常工作时或者当在检测到异常工作之后将混合动力车辆100的工作状况切换到停止状态时,在车辆状态下执行HV系统控制单元4的检测功能。具体而言,混合动力车辆100的工作状况切换到停止状态,并且用于起动检测模式的检测开关等被操作,来起动检测功能。因此,自动执行对HV系统的检测。在执行了一系列检测之后,检测操作自动终止。通过打开异常灯、将数据传递到检测诊断工具等,来输出检测结果。
将描述用HV系统控制单元4来检测混合动力车辆100的方法。如图1所示,变速车轴3的电动机MG1和MG2通过电动机电缆连接到逆变器2。当电动机电流从逆变器2供应到每个电动机时,每个电动机产生转矩。电动机MG1和MG2如上所述电连接到逆变器2。因此,如果逆变器电路Cmg1或Cmg2出现故障或者发生电动机绕组的绝缘异常,则电流将不能正常流动,导致异常输出。通过首先单独检测逆变器2来检查逆变器2是否具有缺陷,然后将电动机MG1和MG2连接到逆变器电路Cmg1和Cmg2来检查电动机是否具有缺陷,来进行本实施例的检测。此外,进行检测来检查具有缺陷的部分是包括在电动机MG1和MG2中还是包括在逆变器电路Cmg1和Cmg2中。
具体而言,将电动机MG1连接到逆变器电路Cmg1(组合A)并且电动机MG2连接到逆变器电路Cmg2(组合B)的状态称为“通常连接模式”。将电动机MG1连接到逆变器电路Cmg2(组合C)并且电动机MG2连接到逆变器电路Cmg1(组合D)的状态称为“互换连接模式”。这些组合在图3中简单示出。在本实施方式的检测中,获得每种组合中电动机的输出特性,并基于得到的输出特性,指明逆变器电路Cmg1、逆变器电路Cmg2、电动机MG1或MG2中具有缺陷的部分。
以下将参考图4和5的流程图来描述对逆变器2以及电动机MG1和MG2进行检测的检测过程。通过检测逆变器2(S1至S3)、在通常连接模式下检测电动机MG1和MG2(S4至S9)、在互换连接模式下检测电动机MG1和MG2(S10至S13)以及判定缺陷单元(S14至S17)来依次进行检测。可以首先进行通常连接模式和互换连接模式下的检测中的任一者。
对逆变器2单独进行电气异常检查检测。在此检测中,将开关12关断以断开变速车轴3与逆变器2之间的电连接,由此断开逆变器电路Cmg1和Cmg2与电动机MG1和MG2之间的电连接。
随后,在S2,为使逆变器电路Cmg1和Cmg2作,将电压以与逆变器电路连接到电动机的情况下的电压相等的电压水平施加到各个逆变器电路。在此状态下,监视每个逆变器电路中是否发生过电流或过电压状态。
在S3,检查在逆变器电路Cmg1和Cmg2中是否已经发生过电流或过电压。通过预先设定在预先指定的电路工作模式下的过电流和过电压的阈值并接着将监视获得的值与阈值比较,来进行该检查。
当在逆变器电路中的至少一个中已经发生了过电流或过电压状态(S3:“是”),则判定逆变器2具有电气缺陷,并且终止当前检测。当两个逆变器电路均正常工作并且尚未发生过电流或过电压状态时(S3:“否”),则处理进行到电动机MG1和MG2的检测。
接着,在以下过程进行电动机MG1和MG2的检测。首先,在S4,从预设检测点选择一个检测点(P_n)。检测点选择顺序是预设的,并且以预设顺序自动选择检测点。选择顺序的设定是任意的。或者,可以由检测者针对每次检测来任意设定选择顺序。表1示出了在检测点(P_n)设定的主要项目。
表1
目标转数 | 目标转矩 |
Nmg1*:电动机MG1的目标转数Nmg2*:电动机MG2的目标转数 | Tmg1*:电动机MG1的目标转矩Tmg2*:电动机MG2的目标转矩 |
接着,在要进行电动机MG1和MG2的检测时,将发动机5的输出轴锁止(S5)。例如,在检测电动机MG1时,电动机MG2在转数控制下运转,而电动机MG1在转矩控制下运转。此时,电动机MG1经由小齿轮33分别连接到发动机5和电动机MG2。因此,为了将电动机MG1的转矩输出到电动机MG2,如果不通过某些手段将发动机5的输出轴锁止,则转矩将传递到发动机5的输出轴,从而使得发动机5的输出轴空转,因此不能测量精确转矩。因此,在检测电动机MG1和MG2时,必须通过发动机轴锁止机构13将发动机5的输出轴锁止。
作为发动机轴锁止机构13,可以采用任意机构,只要其能够锁止将发动机5和变速车轴3连接的轴即可。例如,可以采用电磁制动结构或诸如停车制动机构之类的机械锁止方法。
随后,在S6,以通常连接模式将逆变器2连接到电动机MG1和MG2。具体而言,如图3所示,电动机MG1连接到逆变器电路Cmg1(组合A)并且电动机MG2连接到逆变器电路Cmg2(组合B)。
基于所选择的检测点(P_n)处的参数使电动机MG1和MG2运转,以获得各自的输出特性。为了获得输出特性,执行用于检测电动机MG1的输出特性的操作和用于检测电动机MG2的输出特性的操作。可以首先进行这两个操作中的任一个。
作为用于获得电动机MG1(要检查其输出特性)的转矩的操作,执行电动机MG2的转数控制和电动机MG1的转矩控制(S7-1)。具体而言,通过转矩控制使电动机MG1运转,使得转矩成为目标转矩Tmg1*。通过转数控制使电动机MG2运转,使得电动机MG1的转数成为“目标转数”Nmg1*。具体而言,通过以下算术表达式(1)来计算用于控制电动机MG2转数的转矩,以使电动机MG2加速或减速,从而调节电动机MG1的“转数”Nmg1。
Tmg2=(Nmg2*-Nmg2)×Kp+(Nmg2*-Nmg2)×Ki (1)其中,Tmg2表示电动机MG2的控制转矩,Nmg2*表示电动机MG2的目标转数,Nmg2表示电动机MG2的实际转数,Kp表示比例控制增益,Ki表示积分控制增益。
当在运转过渡时段之后实现输出稳定状态时,电动机MG2的输出转矩Tmg2和作为到电动机MG2的负荷转矩的电动机MG1的电动机转矩Tmg1成为彼此相等。在此状态下的转矩控制值是电动机MG1的检测转矩。
随后,在输出该转矩的状态下,获得输出特性数据(S8-1)。在本实施方式中,获得电动机MG2的控制数据。具体而言,获得在S7-1的处理中使用的电动机MG2的控制转矩Tmg2,并记录在HV系统控制单元4中。作为电动机MG1的输出特性,可以使用电动机MG1的转数Nmg1或供应到电动机MG1的电力。
另一方面,作为用于获得电动机MG2(要检查其输出特性)的操作,执行电动机MG1的转数控制和电动机MG2的转矩控制(S7-2)。具体而言,通过转矩控制使电动机MG2运转,使得转矩成为目标转矩Tmg2*。通过转数控制使电动机MG1运转,使得电动机MG2的转数成为目标转数Nmg2*。具体而言,通过以下算术表达式(2)来计算用于控制电动机MG1转数的转矩,以使电动机MG1加速或减速,从而调节电动机MG2的“转数”Nmg2。
Tmg1=(Nmg1*-Nmg1)×Kp+(Nmg1*-Nmg1)×Ki (2)
其中,Tmg1表示电动机MG1的控制转矩,Nmg1*表示电动机MG1的目标转数,Nmg1表示电动机MG1的实际转数,Kp表示比例控制增益,Ki表示积分控制增益。
当在运转过渡时段之后实现输出稳定状态时,电动机MG1的输出转矩Tmg1和作为到电动机MG1的负荷转矩的电动机MG2的电动机转矩Tmg2成为彼此相等。在此状态下的转矩控制值是电动机MG2的检测转矩。
随后,在输出该转矩的状态下,获得输出特性数据(S8-2)。在本实施方式中,获得电动机MG1的控制数据。具体而言,获得在S7-2的处理中使用的电动机MG1的控制转矩Tmg1,并记录在HV系统控制单元4中。作为电动机MG2的输出特性数据,可以使用电动机MG2的转数Nmg2或供应到电动机MG2的电力。
接着,以互换连接模式将逆变器2连接到电动机MG1和MG2(S9)。具体而言,如图3所示,电动机MG1连接到逆变器电路Cmg2(组合C)并且电动机MG2连接到逆变器电路Cmg1(组合D)。
基于所选择的检测点(P_n)处的参数使电动机MG1和MG2运转,以获得各自的输出特性。为了获得输出特性,执行前述两个操作(一个用于获得电动机MG1的输出特性,另一个用于获得电动机MG2的输出特性)。可以首先进行这两个操作中的任一个。
具体而言,作为用于获得电动机MG1的输出特性的操作,执行电动机MG2的转数控制和电动机MG1的转矩控制(S10-1)。在输出该转矩的状态下,获得输出特性数据(S11-1)。在本实施例方式中,获得电动机MG2的控制数据。具体而言,获得在S10-1的处理中使用的电动机MG2的控制转矩Tmg2,并记录在HV系统控制单元4中。作为用于获得电动机MG2的输出特性数据,执行电动机MG1的转数控制和电动机MG2的转矩控制(S10-2)。在输出该转矩的状态下,获得输出特性数据(S11-2)。在本实施例方式中,获得电动机MG1的控制数据。具体而言,获得在S10-2的处理中使用的电动机MG1的控制转矩Tmg1,并记录在HV系统控制单元4中。
在完成用于检测电动机MG1和MG2的操作之后,解除发动机轴锁止机构13的锁止(S12)。因此,终止电动机MG1和MG2的检测,并且处理进行到检测缺陷单元的判定步骤。
基于由逆变器电路Cmg1和Cmg2与电动机MG1和MG2的组合的操作所检测到的输出特性,判定哪个单元具有缺陷。首先,为了判定组合A中的输出特性数据是否正常,在S13检查在S8-1的处理中获得的输出转矩Tmg2。具体而言,判定输出转矩Tmg2是否位于根据所选择的检测点(P_n)的参数预先设定的上限TmgAU和下限TmgAL之间的范围内。
如果组合A中的输出特性数据位于正常范围内(S13:“是”),则在S14检查S8-2的处理中获得的输出转矩Tmg1来判定组合B中的输出特性数据是否正常。具体而言,判定输出转矩Tmg1是否位于根据所选择的检测点(P_n)的参数预先设定的上限TmgBU和下限TmgBL之间的范围内。
如果组合B中的输出特性数据位于正常范围内(S14:“是”),则判定变速车轴3的电动机MG1和MG2两者均正常。换言之,没有单元被判定为具有缺陷,因此逆变器电路Cmg1和Cmg2以及电动机MG1和MG2均被判定为正常。
另一方面,如果组合A中的输出特性数据位于正常范围之外(S13:“否”),则检查S11-1的处理中获得的输出转矩Tmg2来判定组合C中的输出特性数据是否正常(S15)。具体而言,判定输出转矩Tmg2是否位于根据所选择的检测点(P_n)的参数预先设定的上限TmgCU和下限TmgCL之间的范围内。
如果组合C中的输出特性数据位于正常范围内(S15:“是”),表示逆变器电路Cmg1和逆变器电路Cmg2的互换导致了不同的判定结果,则将逆变器2的逆变器电路Cmg1判定为具有缺陷。相反,如果组合C中的输出特性数据位于正常范围之外(S15:“否”),表示即使在逆变器电路Cmg1和Cmg2互换以连接到电动机MG1之后输出特性数据仍异常,则将电动机MG1判定为具有缺陷。
如果组合B中的输出特性位于正常范围之外(S14:“否”),则检查S11-2的处理中获得的输出转矩Tmg1来判定组合D中的输出特性数据是否正常(S16)。具体而言,判定输出转矩Tmg1是否位于根据所选择的检测点(P_n)的参数预先设定的上限TmgDU和下限TmgDL之间的范围内。
如果组合D中的输出特性数据位于正常范围内(S16:“是”),表示逆变器电路Cmg1和逆变器电路Cmg2的互换导致了不同的判定结果,则将逆变器2的逆变器电路Cmg2判定为具有缺陷。相反,如果组合D中的输出特性数据位于正常范围之外(S16:“否”),表示即使在逆变器电路Cmg1和Cmg2互换之后输出特性数据仍异常,则将电动机MG2判定为具有缺陷。
如上详细解释的,本实施方式的检测系统以如下方式实现:以电动机MG1和MG2与逆变器电路Cmg1和Cmg2的一些组合将变速车轴3连接到逆变器2,并在每种组合下使电动机MG1和MG2运转,并测量每个电动机的输出特性。然后,电动机MG1和MG2到逆变器电路Cmg1和Cmg2的连接在通常连接模式和互换连接模式之间切换。因此在将电动机和逆变器电路组合的四种模式(组合A、B、C和D)的每个模式下进行检测。因而自动地判定每种组合下测量的输出特性是否位于目标范围内。基于检测结果的组合,可以检查哪种模式包括故障,并可以因此指明电动机和逆变器中具有缺陷的一个。具体而言,在电动机输出异常的情况下,如果同一个电动机的输出即使在将逆变器电路互换以连接到该电动机之后仍异常,则可以判定所涉及的电动机具有缺陷。另一方面,即使逆变器电路互换,如果连接到同一个逆变器电路的电动机的输出异常,则可以判定所涉及的逆变器电路具有缺陷。因此,本实施方式的混合动力车辆检测系统和方法可以检测电动机自身的性能,并针对具有较差性能的电动机,指明较差性能是由电动机自身还是逆变器引起。
本实施方式的检测以如下方式进行:将变速车轴3与逆变器2之间的电连接断开,并在电动机MG1和MG2的检测之前仅检测逆变器2。这允许较早地检测逆变器2自身的异常。
根据本实施方式的检测,允许以最终产品形式(以车辆状态)检测混合动力车辆100。因此,该检测不仅可以在车辆制造期间进行,而且还可以在制造结束期间(初始状态)、使用期间(老化变化)以及在故障发生时进行。
以上实施方式仅是示例,其并不限制本发明,并且本发明可以在不脱离其核心特征的情况下以其他具体形式来实施。例如,作为检测对象的混合动力车辆可以不一定处于最终产品形式。具体而言,混合动力车辆仅需要被构造为使得发动机5以及变速车轴3的电动机MG1和MG2被布置为彼此传递动力,并允许各个动力源被控制以运转和被锁止。
