混合动力车辆的故障判定装置及其故障判定方法
技术领域
本发明涉及判定在混合动力车辆中将油泵的喷出压原封不动地向离合器供给的普通MAX压故障的技术。
背景技术
在JP2010－155590A中公开有将发动机和电动机串联配置且在发动机与电动机之间配置有第一离合器，在电动机与驱动轮之间配置有第二离合器的混合动力车辆。
在这种构成的混合动力车辆中，若将第一离合器释放且将第二离合器联接，则成为仅利用电动机行驶的EV模式，若将第一离合器及第二离合器联接，则成为利用发动机及电动机行驶的HEV模式。
另外，在起步时或减速停车时，通过进行使第二离合器滑动的WSC(Wet StartClutch)控制，不借助液力变矩器而实现顺畅的起步及停车。
向上述第二离合器供给的油压以通过传递电动机的旋转而动作的油泵的喷出压为初始压，通过油压控制阀单元进行调压。
然而，如果油压控制阀单元发生动作不良(例如，对向第二离合器供给的油压进行调压的电磁阀的动作不良)，产生油泵的喷出压被原封不动地向第二离合器供给的普通MAX压故障的话，则在上述WSC控制时第二离合器的容量波动。产生第二离合器的波动的机理如下。
例如，如果在起步时发生普通MAX故障，则油泵的喷出压被原封不动地供给第二离合器，在第二离合器的容量大的状态下起步。
然而，如果第二离合器的容量大，则从驱动轮侧对电动机作用负荷，故而电动机的旋转下降，油泵的喷出压降低，作为结果，第二离合器的容量转向减少。
而且，如果第二离合器的容量下降，则第二离合器滑动，电动机从驱动轮释放，如果为这种状态，则电动机的旋转上升，油泵的喷出压上升，故而第二离合器的容量转向增大。
这样，若第二离合器的容量增大，则之后容量转向减少，相反地，若第二离合器的容量减少，则之后容量转向增大，因此，第二离合器的容量波动。在减速停车时进行WSC控制的情况也因同样的原因而使第二离合器的容量波动。
如果第二离合器的容量波动，则油压控制阀单元的调压值波动，故而第二离合器的容量增减，第二离合器无法正常发挥功能。
此外，未伴随WSC控制的起步离合器一般的技术为，基于选档时离合器从释放的状态到联接的状态的时间，检测正常或失常。这是因为MAX压故障的情况下，离合器从释放的状态至联接的状态的时间变短，故而能够检测失常。
进行WSC控制的起步离合器也同样，在选档时可检测失常，但如果失常的检测延迟，则导致换档质量、发动机失速等行驶性能恶化，具有在选档前的行驶状态，要急速进行失常检测的要求。

具体实施方式
以下，参照附图并对本发明的实施方式进行说明。
图1是混合动力车辆(以下称为车辆)100的整体构成图。车辆100具备发动机1、第一离合器2、电动发电机(以下称为MG)3、第一油泵4、第二油泵5、第二离合器6、无级变速器(以下称为CVT)7、驱动轮8、综合控制器50。
发动机1是以汽油、柴油等为燃料的内燃机，基于来自综合控制器50的指令控制转速、扭矩等。
第一离合器2是安装于发动机1与MG3之间的常开型的油压式离合器。第一离合器2基于来自综合控制器50的指令，通过以第一油泵4或第二油泵5的喷出压为初始压而由油压控制阀单元71调节的油压，控制联接、释放状态。作为第一离合器2，例如使用干式多板离合器。
MG3相对于发动机1串联配置，是在转子上埋设永久磁铁并在定子上卷绕有定子线圈的同步型旋转电机。MG3基于来自综合控制器50的指令，通过施加由变换器9制成的三相交流来控制。MG3能够作为接受来自蓄电池10的电力供给而旋转驱动的电动机进行动作。另外，MG3在转子从发动机1或驱动轮8接受旋转能量的情况下，作为在定子线圈的两端产生电动势的发电机发挥功能，能够对蓄电池10充电。
第一油泵4是通过经由带4b传递MG3的旋转而进行动作的叶片泵。第一油泵4吸起在CVT7的油盘72贮存的动作油，向油压控制阀单元71供给油压。
第二油泵5是从蓄电池10接受电力供给而进行动作的电动油泵。第二油泵5基于来自综合控制器50的指令，在仅利用第一油泵4油量不足的情况下被驱动，与第一油泵4同样地，吸起在CVT7的油盘72贮存的动作油，向油压控制阀单元71供给油压。
第二离合器6安装在MG3与CVT7及驱动轮8之间。第二离合器基于来自综合控制器50的指令，通过以第一油泵4或第二油泵5的喷出压为初始压由油压控制阀单元71调节的油压，控制联接、释放。作为第二离合器6，例如使用常开型的湿式多板离合器。
CVT7配置在MG3的下游，能够根据车速及加速踏板开度等无级地变更变速比。CVT7具备初级带轮、次级带轮、卷挂于两带轮的带。以来自第一油泵4及第二油泵5的喷出压为初始压，通过油压控制阀单元71制成初级带轮压和次级带轮压，通过带轮压使初级带轮的可动带轮和次级带轮的可动带轮沿轴向移动，使带的带轮接触半径变化，由此无级地变更变速比。
CVT7的输出轴经由未图示的终端减速齿轮机构与差速器12连接，差速器12经由驱动轴13连接驱动轮8。
向综合控制器50输入来自检测发动机1的转速的转速传感器51、检测第二离合器6的输出转速(＝CVT7的输入转速)的转速传感器52、检测加速踏板开度的加速踏板开度传感器53、检测CVT7的选档位置(切换前进、后退、空档及停车的选档杆或选档开关的状态)的档位开关54、检测车速的车速传感器55等的信号。综合控制器50基于输入的这些信号，进行对发动机1、MG3(变换器9)、CVT7的各种控制。
另外，综合控制器50参照图2所示的模式切换映像图，作为车辆100的运转模式，切换EV模式和HEV模式。
EV模式是释放第一离合器2，仅以MG3作为驱动源行驶的模式。在要求驱动力低，蓄电池10的充电量充分时选择EV模式。
HEV模式是联接第一离合器2，以发动机1和MG3为驱动源行驶的模式。在要求驱动力高时或蓄电池10的充电量不足时选择HEV模式。
此外，从EV模式向HEV模式的切换线以EV模式和HEV模式的切换不波动的方式设定在比从HEV模式向EV模式的切换线靠高车速侧且加速踏板开度大侧。
另外，车辆100不具备液力变矩器，故而在图2所示的WSC区域(起步和减速停车时使用的车速为VSP1以下的低车速区域，VSP1例如为10km/h)，综合控制器50进行一边使第二离合器6滑动一边起步及停止的WSC控制。
具体而言，在CVT7的选档位置从非行驶位置(N、P等)切换到行驶位置(D、R等)而使车辆100起步的情况下，综合控制器50使向第二离合器6供给的油压逐渐增大，一边使第二离合器6滑动一边缓缓地联接。而且，若车速达到VSP1，则综合控制器50将第二离合器6完全联接，结束WSC控制。
另外，车辆100在CVT7的选档位置为行驶位置(D、R等)行驶，车辆100减速，车速降低至VSP1的情况下，综合控制器50使向第二离合器6供给的油压逐渐降低，一边使第二离合器6滑动一边缓缓地释放。而且，若车辆100停车，则综合控制器50将第二离合器6完全释放，结束WSC控制。
这样，WSC控制以第二离合器6滑动的方式细微地控制向第二离合器6供给的油压，油压控制阀单元71需要正常地发挥功能。
因此，如果产生油压控制阀单元71的动作不良(例如，对向第二离合器6供给的油压进行调压的电磁阀动作不良)，发生将第一油泵4的喷出压原封不动地向第二离合器6供给的普通MAX压故障的话，则如在发明要解决的课题栏中所说明地，第二离合器6的容量波动。
因此，综合控制器50进行以下说明的故障判定处理，进行是否在第二离合器6发生普通MAX压故障的判定。
图3是表示综合控制器50进行的故障判定处理的内容的流程图。参照此流程图对综合控制器50进行的故障判定处理进行说明。
首先，在S1中，综合控制器50判断是否发出了WSC过渡指示。判断输出了WSC过渡指示的情况下，处理进入S2。
WSC过渡指示在选档位置从非行驶位置切换到行驶位置时(起步时)或在行驶位置行驶中车辆100减速，车速降低至VSP1时(减速停车时)发出。
如果发出WSC过渡指示，则综合控制器50只要是起步时，就以使向第二离合器6供给的油压逐渐增大的方式，或只要是减速停车时，就以使向第二离合器6供给的油压逐渐减少的方式向油压控制阀单元71发出指示，由此，将第二离合器6控制为滑动状态。
在S2中，综合控制器50根据WSC过渡指示判断是否经过规定时间。根据WSC过渡指示判断为经过规定时间的情况下，处理进入S3。
这是用于防止在发出WSC过渡指示后实际上成为WSC状态为止具有延迟，实际上在成为WSC状态之前进行S3过渡的处理。发出WSC过渡指示后实际上成为WSC状态的延迟依赖于油温(动作油的粘度)，油温越低，延迟越大，故而规定时间以油温越低越长的方式设定。
在S3中，综合控制器50判断MG3的转速是否比失速判定值高，且是否比怠速转速低。失速判定值是判定发动机1是否失速的阈值。怠速转速是在未踏下加速踏板的状态下的MG3的目标转速。
在判定为MG3的转速比失速判定值高且比怠速转速低的情况下，处理进入S4。
在S4中，综合控制器50判断第二离合器6的旋转差、即输入侧转速(＝MG3的转速)和输出侧转速之差即旋转差的绝对值是否低于联接判定阈值。联接判定阈值是判断第二离合器6完全联接或接近完全联接的状态的阈值。
在判断为第二离合器6的旋转差低于联接判定阈值的情况下，处理进入S5。
在处理进入S5的情况下，在S3、S4中进行肯定的判断，发动机1未失速，MG3的旋转下降至低于怠速转速，且第二离合器6是完全联接或接近完全联接的状态，因此，发生第一油泵4的喷出压被原封不动地向第二离合器6供给的普通MAX压故障的可能性高。因此，在S5中，综合控制器50起动累积计时器，求出判断为在第二离合器6发生普通MAX压故障的可能性高的时间的累积值。
而且，在S6中，综合控制器50判断累积计时器的值是否比故障判定阈值大。在判断为累积计时器的值比故障判定阈值大的情况下，处理进入S7。
累积计时器在点火开关变为OFF的定时或点火开关变为ON的定时复位为零。因此，是否在第二离合器6发生普通MAX压故障基于一次行程(即从将键接通开始行驶到将键断开结束行驶的一次行驶)中的累积计时器的值判断。
在S7中，综合控制器50判定为在第二离合器6发生普通MAX压故障。
在S8中，综合控制器50判断是否发出了WSC结束指示。判断为发出了WSC结束指示的情况下，处理结束，在判断为未发出WSC结束指示的情况下，处理返回S3，反复进行S3～S9的处理直至发出WSC结束指示。
若为起步时，则在车速达到VSP1的情况下发出WSC结束指示，若为减速停车时，则在车辆100停车的情况下发出WSC结束指示。若发出WSC结束指示，则只要起步时，向第二离合器6供给的油压就提高至第二离合器6完全联接的油压，只要是减速停车时，就以第二离合器6释放的方式使向第二离合器6供给的油压变为零。
在S3中，判断为MG3的转速比失速判定值低的情况下，处理进入S9，停止累积计时器。这是因为，发动机1失速的情况下MG3的转速也低于怠速转速，故而防止弄错该情况而判断为在第二离合器6由普通MAX压故障引起的情况并更新累积计时器。
另外，在S3中判断为MG3的转速为怠速转速以上的情况及在S4中判断为第二离合器6的旋转差比联接判定阈值大的情况下，处理也进入S9，停止累积计时器。这是因为，不发生MG3的转速的下降，另外，只要是第二离合器6滑动的情况，则也不在第二离合器6发生普通MAX压故障，因此，这种情况下也不更新累积计时器。
接着，对进行上述故障判定处理的作用效果进行说明。
图4A是表示在第二离合器6未发生普通MAX压故障时进行上述故障判定处理的情形的时间图。
在该例中，在时刻t11发出WSC过渡指示，在时刻t12实际上为WSC状态。由于不在第二离合器6发生普通MAX压故障，故而通过WSC控制使向第二离合器6供给的油压逐渐提高，第二离合器6的容量逐渐提高，第二离合器6一边滑动一边缓缓联接。
由此，在第二离合器6的旋转差逐渐缩小，车速达到VSP1而脱离WSC状态的时刻t13，第二离合器6的旋转差为零，第二离合器6完全联接。
WSC控制中，MG3的转速不低于怠速转速，另外，在WSC状态下第二离合器6的旋转总是比零大，故而累积计时器不进行计时，判断为在第二离合器6未发生普通MAX压故障。
对此，图4B是表示在第二离合器6发生普通MAX压故障时进行上述故障判定处理的情形的时间图。
在时刻t21发出WSC过渡指示，但在第二离合器6发生普通MAX压故障，故而第二离合器6经过了延迟时间后，立即成为完全联接状态。该结果是，从驱动轮8侧对MG3施加负荷，第二离合器6的旋转差大致为零(时刻t22)。
时刻t22以后反复进行下述动作：MG3的转速降低，第一油泵4的喷出压下降，第二离合器6的容量转向减小的动作；接受第二离合器6的容量降低的影响，第二离合器6滑动，从驱动轮8释放的MG3的转速上升，第一油泵4的喷出压上升，第二离合器6的容量转向增大的动作，而使第二离合器6的容量波动。该波动持续到车速上升至与MG3的转速对应的车速的时刻t24继续。
这样，如果在第二离合器6发生普通MAX压故障，则第二离合器6的容量波动，但根据上述故障判定处理，判断为MG3的转速低于怠速转速，且第二离合器6的旋转差低于联接判定阈值的时间的累积值通过累积计时器求出。而且，在该例中，在时刻t23，累积值超过故障判定阈值，故而判定为在第二离合器6发生普通MAX压故障。
因此，根据上述故障判定处理，能够判定在第二离合器6发生普通MAX压故障。另外，在起步或减速停车时进行故障判定，故而能够充分确保故障判定的机会。
另外，如果MG3的转速低于怠速转速，且第二离合器6的旋转差低于联接判定阈值，则不立即判定为在第二离合器6发生普通MAX压故障，而在成为相同状态的时间的累积值超过故障判定阈值的情况下，判定为在第二离合器6发生普通MAX压故障。
由此，没有受到传感器检测值中包含的干扰及向第二离合器6的供给压暂时增高的情况而误判定，能够以高精度判定是否在第二离合器6发生普通MAX压故障。
另外，即使是通过驾驶者的运转特性及WSC控制的调整，在一次的起步或减速停车中判断为上述状态的时间缩短的情况，通过基于累积值进行判断，也能够判定是否在第二离合器6发生普通MAX压故障。
另外，发动机1失速的情况不使累积计时器计时。由此，能够防止在由于发动机1的失速而使MG3的转速低于怠速转速的情况下，误判断为在第二离合器6发生普通MAX压故障的情况。
以上，对于本发明的实施方式进行了说明，但上述实施方式只不过表示了本发明的应用例的一部分，不是将本发明的技术范围限定于上述实施方式的具体构成的意思。
