车辆的控制装置及控制方法
技术领域
本发明涉及一种具备发动机及电动机作为动力源的车辆的控制。
背景技术
已知有一种混合动力车辆，其具备发动机、与无级变速器的初级带轮连接的电动机、以及将发动机和无级变速器的动力传递断开/连接的联接元件，可选择使用发动机的动力的发动机行驶模式和使用电动机的动力的电动行驶(下面，也称为EV行驶)模式。JP2000－71815A中公开有如下控制：在上述结构的混合动力车辆从EV行驶模式向发动机行驶模式转换时，抑制伴随模式切换的冲击。具体而言，公开有一种扭矩切换控制：在释放联接元件的状态下开始起动发动机，在发动机起动后限制发动机的扭矩，在将联接元件联接后，使发动机的扭矩递增，同时使电动机的扭矩递减，由此，抑制传递到驱动轮的扭矩的变动。
发明要解决的问题
在上述文献所记载的结构中，在发动机和无级变速器之间未配置液力变矩器，但从联接元件的联接、释放控制的简化或联接元件的耐久性提高等观点来看，也考虑设置液力变矩器。
但是，在设置有液力变矩器的情况下，如果在释放锁止离合器的状态下执行专利文献1的控制，则尽管在发动机起动后限制发动机的扭矩，液力变矩器的输出侧的扭矩在联接元件联接后通过液力变矩器的扭矩放大作用也会增大，可能发生冲击。
发明内容
于是，本发明的目的在于，在具备液力变矩器的结构中，抑制在释放锁止离合器的状态下从EV行驶模式向发动机行驶模式转换(过渡)时的冲击。
用于解决问题的技术方案
根据本发明的一方式，提供一种控制装置，其对车辆进行控制，该车辆具有：发动机；液力变矩器，其在动力传递路径中位于发动机的下游，且具有锁止离合器；联接元件，其在动力传递路径中位于液力变矩器的下游；驱动轴，其在动力传递路径中位于联接元件的下游；电动机，其在动力传递路径中位于联接元件的下游，且与驱动轴连接。该控制装置具备控制部，该控制部在进行从在释放锁止离合器的状态且释放联接元件的状态下使电动机旋转的电动行驶模式，向在释放锁止离合器的状态且联接联接元件的状态下使发动机旋转的发动机行驶模式的切换的情况下，在联接元件联接后使电动机的驱动扭矩减小，在电动机的驱动扭矩减小后，使发动机的驱动扭矩递增，同时使电动机的驱动扭矩递减。
另外，根据本发明的另一方式，提供一种控制车辆的方法，该车辆具有：发动机；液力变矩器，其在动力传递路径中位于发动机的下游，且具有锁止离合器；联接元件，其在动力传递路径中位于液力变矩器的下游；驱动轴，其在动力传递路径中位于联接元件的下游；电动机，其在动力传递路径中位于联接元件的下游，且与驱动轴连接。该控制方法在进行从在释放锁止离合器的状态且释放联接元件的状态下使电动机旋转的电动行驶模式，向在释放锁止离合器的状态且联接联接元件的状态下使发动机旋转的发动机行驶模式的切换的情况下，在联接元件联接后使电动机的驱动扭矩减小，在电动机的驱动扭矩减小后，使发动机的驱动扭矩递增，同时，使电动机的驱动扭矩递减。
根据上述方式，能够抑制在释放锁止离合器的状态下从EV行驶模式向发动机行驶模式转换时的冲击。

具体实施方式
下面，参照附图对本发明的实施方式进行说明。
图1是应用本实施方式的混合动力车辆(下面，也简称为“车辆”)的概略结构图。车辆具备发动机1、无级变速器***2、电动发电机(下面，也称为MG)3、电动油泵6、驱动轮8、控制器100。
发动机1是以汽油或柴油为燃料的内燃机，基于来自控制器100的指令对转速、扭矩等进行控制。
无级变速器***2具备液力变矩器9、作为联接元件的前进离合器10、变速机构11、末端传动齿轮装置13、油泵22。
液力变矩器9具备叶轮14、涡轮15、锁止离合器16。如果将锁止离合器16联接，则液力变矩器9的输入轴和输出轴成为直接连接状态，输入轴和输出轴以相同速度旋转。下面，也将锁止离合器16称为LU离合器16。后述将LU离合器16联接、释放的条件。
变速机构11具备初级带轮11A、次级带轮11B、带12。在变速机构11中，对向初级带轮11A供给的油压和向次级带轮11B供给的油压进行控制而变更各带轮11A、11B和带12的接触半径，由此，变更变速比。
前进离合器10配置于液力变矩器9和初级带轮11A之间。如果将前进离合器10联接，则发动机1的驱动扭矩经由驱动轴17、18向初级带轮11A传递。根据驾驶状态，通过控制器100对前进离合器10的联接、释放进行切换。此外，在本说明书中，驱动扭矩是指使驱动轮8旋转的扭矩(正扭矩)。因此，成为妨碍驱动轮8旋转的负荷的扭矩是指负扭矩。另外，在本说明书中，有时也将驱动扭矩简称为“扭矩”。
此外，在图1中，前进离合器10配置于液力变矩器9和初级带轮11A之间，但不限于此。设置前进离合器10的目的是将发动机1和驱动轮8之间的动力传递路径断开/连接，因此，前进离合器10例如也可以配置于次级带轮11B和末端传动齿轮装置13之间。
MG3经由由带及带轮构成的传递机构20与初级带轮11A的旋转轴连接。MG3是将永磁铁埋设于转子内且将定子线圈卷绕于定子上的同步旋转电机。MG3基于来自控制器100的指令，通过施加由逆变器4产生的三相交流电进行控制。MG3能够作为接收来自蓄电池5的电力的供给而进行旋转驱动的电动机进行动作。蓄电池5例如是48[V]的高压蓄电池。因此，MG3作为电动机进行动作而使EV行驶成为可能。另外，在转子从发动机1或驱动轮8接收旋转能量的情况下，MG3作为在定子线圈的两端产生电动势的发电机发挥作用，能够对蓄电池5进行充电。即，MG3能够以车辆的动能为电力进行再生。在车辆减速时等执行再生控制。
油泵22经由由带及带轮构成的传递机构21与发动机1的输出轴连接。就油泵22而言，被输入发动机1的旋转，利用发动机1的动力的一部分而进行驱动。将从油泵22排出的油向包含变速用回路的车辆的油压控制回路供给。
此外，除油泵22外，车辆也具备电动油泵6。电动油泵6基于来自控制器100的指令，通过施加由逆变器7产生的三相交流电进行控制。因此，电动油泵6在发动机1停止的情况下也可进行动作。从电动油泵6排出的油也被供给到油压控制回路。因此，无级变速器***2基于来自油泵22或电动油泵6中的至少任一个的供给油压进行控制。
将来自检测发动机转速Ne的发动机转速传感器25的信号、来自检测加速器开度APO的加速器开度传感器23的信号、来自检测基于制动器踏板的踩下量BPR的制动器踏板力的制动器传感器24的信号输入到控制器100。此外，除这些外，也将未图示的检测初级带轮11A的转速的传感器、检测次级带轮11B的转速的传感器等的各检测信号输入到控制器100。
控制器100由具备中央处理器(CPU)、只读存储器(ROM)、随机存取存储器(RAM)及输入输出接口(I/O接口)的微型计算机构成。控制器100也可以由多个微型计算机构成。
在上述结构中，由发动机1产生的动力经由液力变矩器9、驱动轴17、前进离合器10、驱动轴18、变速机构11、驱动轴19、末端传动齿轮装置13向驱动轮8传递。由MG3产生的动力经由变速机构11、驱动轴19、末端传动齿轮装置13向驱动轮8传递。
控制器100根据行驶状态对通过发动机1的动力进行行驶的发动机行驶模式和通过MG3的动力进行行驶的EV行驶模式进行切换。控制器100在发动机行驶模式下联接前进离合器10，在EV行驶模式下释放前进离合器10。
图2是表示对LU离合器16的联接和释放进行切换的锁止切换线、和发动机行驶区域与EV行驶区域的切换线的驾驶区域图。横轴为车速，纵轴为驱动力。此外，纵轴的驱动力也可以置换为加速器开度。
如图示，EV行驶模式和发动机行驶模式主要根据请求驱动力进行切换。另外，LU离合器16的联接和释放主要根据车速进行切换。此外，在发动机行驶模式中也可以进行基于MG3的扭矩辅助。
在从EV行驶模式向发动机行驶模式的切换中有图中箭头所示的A～C三个模式。模式A是从LU离合器16为联接(接通)状态的EV行驶模式向LU离合器16为联接状态的发动机行驶模式的切换。模式B是从LU离合器16为联接状态的EV行驶模式向LU离合器16为释放(断开)状态的发动机行驶模式的切换。模式C是从LU离合器16为释放状态的EV行驶模式向LU离合器16为释放状态的发动机行驶模式的切换。
在从EV行驶模式向发动机行驶模式切换时，控制器100将前进离合器10从释放状态切换成联接状态。此时，为了抑制伴随前进离合器10联接的冲击，控制器100执行前进离合器10的同步旋转控制。在此所述的同步旋转控制是使前进离合器10的输入侧的转速和输出侧的转速之差小到不发生冲击或可允许的冲击的大小的控制。具体而言，通过使发动机转速上升，使前进离合器10的输入侧的驱动轴17的转速上升而接近前进离合器10的输出侧的驱动轴18的转速。
图3是进行模式A的切换的情况下的时序图。
如果在时刻T1踩下加速器，则控制器100确定从EV行驶模式向发动机行驶模式切换。控制器100在时刻T2使油压上升至待机油压，以备前进离合器10的联接，并且为了提高加速度而使MG3的扭矩增大。之后，控制器100为了使发动机1起动而开始转动曲轴。在时刻T3以后，如果发动机1起动，则控制器100为了同步旋转而提高发动机转速，同时通过点火时刻的延迟角等限制发动机1的扭矩。为了抑制联接前进离合器10时的顿挫感或冲击而进行该发动机1的扭矩限制。
在模式A下，LU离合器16为联接状态，因此，涡轮15的转速、即前进离合器10的输入侧的轴即驱动轴17的转速与发动机转速相同。另外，前进离合器10的输出侧的轴即驱动轴18的转速与MG3的转速相同。
在MG3的转速与涡轮15的转速之差小于阈值的时刻T4，控制器100开始前进离合器10的联接。而且，如果前进离合器10的联接在时刻T5结束，则控制器100从发动机1的扭矩限制结束的时刻T6开始使发动机1的扭矩递增，并且使MG3的扭矩递减。此时，对发动机1的扭矩及MG3的扭矩进行控制，以使发动机1的扭矩和MG3的扭矩相加后的扭矩(PRI合计扭矩)不发生变动。如果MG3的扭矩在时刻T7为零，则扭矩的切换控制结束。
图4是通过与模式A的情况同样的控制进行模式C的切换的情况下的时序图。在此，以与模式A的不同点为中心进行说明。
在模式C下，在EV行驶模式下LU离合器16为释放状态，因此，在时刻T3以后，涡轮15的转速比发动机转速更延迟地上升。而且，LU离合器16为释放状态，从而在前进离合器10的联接在时刻T5结束的时刻，涡轮的扭矩(图中的Tbn扭矩)相对于发动机1的扭矩(曲轴扭矩)增大液力变矩器9的扭矩放大量。因此，在时刻T5，PRI合计扭矩增大。
即，尽管进行了发动机1的扭矩限制，传递到驱动轮8的扭矩(PRI合计扭矩)通过扭矩放大作用也会增大，给驾驶员带来冲出感或冲击等不适感。
如上述，如果将适于LU离合器16为联接状态的模式A的控制应用于LU离合器16为释放状态的模式C，则会给驾驶员带来不适感。
另外，在模式B的情况下，根据释放LU离合器16的时刻，传递到驱动轮8的扭矩可能发生变动。例如，如果在从前进离合器10联接结束后到扭矩切换结束为止的期间释放LU离合器16，则发动机转速和涡轮15的转速存在差，扭矩变动也随之发生。
于是，在本实施方式中，为了抑制上述的伴随从EV行驶模式向发动机行驶模式的切换的扭矩变动，执行如下说明的控制。
图5是表示控制器100执行的控制程序的流程图。
在步骤S10中，控制器100判定有无从EV行驶模式向发动机行驶模式的切换请求。在有切换请求的情况下，执行步骤S20的处理，在没有的情况下，结束本程序。基于加速器开度及车速判定有无切换请求。具体而言，通过使用根据加速器开度确定的请求驱动力和当前的车速并对图2所示的图进行检索而判定。
在步骤S20中，控制器100开始发动机1的起动控制。在起动发动机后，控制器100根据点火时期延迟角等限制发动机扭矩，同时为了进行上述的同步旋转而使发动机转速上升。
此外，因为从发出发动机起动的指令到发动机1起动需要时间，所以在步骤S20中，也可以为了使车辆加速而使MG3的扭矩增大。
在步骤S30中，控制器100判定从发动机转速减去初级带轮11A的转速的值是否在阈值以下。该判定是对同步旋转是否结束，即前进离合器10的输入侧的转速和输出侧的转速是否同步进行的判定。
此外，如果出于同步旋转的目的，则理想的是基于涡轮15的转速与初级带轮11A的转速之差进行判断。但是，如果为了进行同步旋转而追加检测涡轮15的转速的传感器，则会导致成本增加。另外，就涡轮15的转速而言，如果LU离合器16联接，则与发动机转速相等，即使释放LU离合器16，通过考虑液力变矩器9中的转速的偏移也能够根据发动机转速进行推测。于是，预先研究液力变矩器9中的转速的偏移，在步骤S30中使用发动机转速判定是否同步旋转。
另外，将用于判定的阈值设定为，发动机转速与涡轮15的转速之差越大而越大的值。其原因在于，在LU离合器16为释放状态时涡轮15的转速比发动机转速更延迟地上升。即，例如，如果将阈值设为零，则在发动机转速和初级带轮11A的转速之差为零的时刻，涡轮15的转速不与初级带轮11A的转速相等，如果将前进离合器10联接，则会发生冲击。
控制器100在步骤S30的判定结果为是的情况下，执行步骤S40的处理，在否的情况下，反复进行步骤S30的判定。
在步骤S40中，控制器100使前进离合器10联接。此外，在联接之前，使前进离合器10的油压上升至待机油压。上升至待机油压的时刻例如与步骤S20中的发动机起动的时刻一致。
在步骤S50中，控制器100判定LU离合器16是否为联接状态，如果为联接状态，则在步骤S60中执行联接状态用(LU－接通用)控制，如果为释放状态，则在步骤S70中执行释放状态用(LU－断开用)控制。
步骤S60中执行的联接状态用控制如下。
首先，使MG3的扭矩递减至零，随之使发动机1的扭矩递增，以使PRI合计扭矩不发生变动。而且，如果MG3的扭矩为零，即如果扭矩的切换控制结束，则释放LU离合器16。在使LU离合器16从联接状态向释放状态过渡的情况下，如果在从前进离合器10联接后到扭矩的切换控制为止的期间释放LU离合器16，则会发生图4中说明的扭矩变动。
另外，如果在前进离合器10联接前释放LU离合器16，则会产生以下问题。第一，液力变矩器9的输出侧的扭矩，即涡轮15的扭矩的控制变得困难。第二，为了使液力变矩器9的输出侧的转速，即涡轮15的转速上升至初级带轮11A的转速，需要使发动机1的转速升高液力变矩器9中的偏移量，因此，会产生燃料的额外消耗或同步旋转结束所需的时间延长等问题。
于是，在联接状态用控制中，在扭矩的切换控制结束后释放LU离合器16。由此，能够解决上述问题。
就步骤S70中执行的释放状态用控制而言，首先，根据后述的方法推定联接前进离合器10时的涡轮15的扭矩和发动机1的扭矩之差，在联接前进离合器10时，使MG3的扭矩减小该扭矩的差量。之后，与联接状态用控制同样，使MG3的扭矩递减，同时使发动机1的扭矩递增。
涡轮15的扭矩和发动机1的扭矩之差的推定方法如下。
首先，基于发动机转速，推定联接前进离合器10时的发动机转速和涡轮15的转速之差(旋转差)。而且，基于所推定的旋转差推定扭矩放大作用量的扭矩。由此，所推定的扭矩是涡轮15的扭矩和发动机1的扭矩之差的推定值。因为扭矩放大作用根据液力变矩器9的特性而确定，所以预先研究所使用的液力变矩器的特性。
如上述，在本实施方式中，在从LU离合器16为释放状态且前进离合器10为释放状态的EV行驶模式，向LU离合器16为释放状态且前进离合器10为联接状态的发动机行驶模式切换时，控制器100在开始前进离合器10联接后使MG3的扭矩减小。而且，在MG3的扭矩减小后开始扭矩的切换控制。
接下来，对执行图5的控制程序的情况下的作用效果进行说明。
图6是执行图5的控制程序的情况下的时序图。从时刻0到时刻T4及时刻T6以后与图4同样，因此省略说明。
在本实施方式中，在前进离合器10联接结束的时刻T5，执行上述的释放状态用控制。即，在时刻T5，使MG3的扭矩减小发动机1的扭矩与涡轮15的扭矩的差量。由此，抑制图4中产生的时刻T5的PRI轴合计扭矩的增大。即，抑制伴随前进离合器10联接的顿挫感或冲击。
如上所述，在本实施方式中，提供一种车辆的控制装置，上述车辆具有：发动机1；液力变矩器9，其在动力传递路径中位于发动机1的下游，且具有LU离合器16；前进离合器10(联接元件)，其在动力传递路径中位于液力变矩器9的下游；驱动轴18，其在动力传递路径中位于前进离合器10的下游；MG(电动机)3，其在动力传递路径中位于前进离合器10的下游，且与驱动轴18连接。该控制装置具备控制器100(控制部)，上述控制器100(控制部)在进行从释放LU离合器16的状态且释放前进离合器10的状态下的EV行驶模式，向释放LU离合器16的状态且联接前进离合器10的状态下的发动机行驶模式的切换的情况下，在前进离合器10联接后使MG3的驱动扭矩减小，在MG3的驱动扭矩减小后，使发动机1的驱动扭矩递增，同时使MG3的驱动扭矩递减。
如上述，在前进离合器10联接后使MG3的驱动扭矩减小，由此，能够抑制前进离合器10联接后的PRI轴合计扭矩的变动，因此，能够抑制伴随前进离合器10联接的冲击。另外，在使MG3的驱动扭矩减小而在抑制冲击的同时将前进离合器10联接后，通过在使发动机1的驱动扭矩递增的同时使MG3的驱动扭矩递减，能够在抑制传递到驱动轮8的扭矩的变动的同时进行扭矩的切换。
在本实施方式中，控制器100将在前进离合器10联接后使MG3的驱动扭矩减小时的扭矩减小量设为，消除了前进离合器10联接结束时的液力变矩器9的扭矩放大作用导致的液力变矩器9的输出侧的扭矩的增大量的大小。由此，由于消除了前进离合器10联接后的液力变矩器9的输出侧的扭矩的增大，因此，能够将PRI轴合计扭矩维持一定而抑制伴随前进离合器10联接的冲击。
在本实施方式中，控制器100在进行从联接LU离合器16的状态且释放前进离合器10的状态下的电动行驶模式，向释放LU离合器16的状态且联接前进离合器10的状态下的发动机行驶模式的切换的情况下，在前进离合器10联接后，使发动机1的驱动扭矩递增，同时使MG3的驱动扭矩递减，之后释放LU离合器16。由此，能够抑制PRI轴合计扭矩的变动，同时进行扭矩的切换控制及LU离合器16的释放。
在本实施方式中，控制器100在进行从EV行驶模式向发动机行驶模式的切换的情况下，在前进离合器10同步旋转时联接前进离合器10。由此，能够抑制伴随前进离合器10联接的冲击。
如上所述，对本发明的实施方式进行了说明，但上述实施方式仅示出了本发明的应用例的一部分，并不旨在将本发明的技术范围限定于上述实施方式的具体结构中。
