Description

用于混合动力车辆的控制设备
技术领域
本发明涉及一种适用于混合动力车辆的控制设备，在所述混合动力车辆中设置有双离合器变速器并且电动机分别与该变速器的两个输入轴连接。
背景技术
已知一种双离合器变速器，其中在第一输入轴与输出系统之间和第二输入轴与输出系统之间分别设置有齿轮系并且这两个输入轴中的一个输入轴选择性地与内燃发动机连接。此外，已知一种混合动力车辆，在该混合动力车辆上装设有上述双离合器变速器并且电机分别与该变速器的输入轴连接(参看日本专利申请公报(No.2003-079005(JP 2003-079005 A))。在JP 2003-079005 A中所述的车辆中，当在车辆利用发动机的驱动力行驶时通过第一电机和第二电机中的一者来辅助发动机的驱动力时，与电机中的另一者相关地设置的传动齿轮的套筒全都被置于空档状态下。
在JP 2003-079005 A中所述的车辆中，在车辆利用发动机的驱动力行驶并且正通过一个电机来辅助驱动力的情况下，当制动踏板被踏压以要求涉及降档的必要性的减速时，与另一个电机相关的套筒在制动踏板已被踏压之后被致动。因此，降档所需的时间会延长。
发明内容
本发明提供了一种用于混合动力车辆的控制设备，其在提高燃料经济性的同时能够在减速时快速降档。
本发明的第一方面提供了一种用于混合动力车辆的控制设备。所述混合动力车辆包括：内燃发动机；双离合器变速器，所述双离合器变速器具有经由第一离合器与所述内燃发动机连接的第一输入轴、经由第二离合器与所述内燃发动机连接的第二输入轴、以能传递动力的方式与驱动轮连接的输出系统、具有介设在所述第一输入轴与所述输出系统之间的第一齿轮系和介设在所述第二输入轴与所述输出系统之间的第二齿轮系的多个齿轮系——所述第一齿轮系和所述第二齿轮系具有相互不同的变速比、构造成能在所述第一输入轴和所述输出系统之间的动力传递由介设在所述第一输入轴与所述输出系统之间的一个所述齿轮系建立的接合状态与所述第一输入轴和所述输出系统之间的动力传递被切断的空档状态之间切换的第一变速机构、以及构造成能在所述第二输入轴和所述输出系统之间的动力传递由介设在所述第二输入轴与所述输出系统之间的一个所述齿轮系建立的接合状态与所述第二输入轴和所述输出系统之间的动力传递被切断的空档状态之间切换的第二变速机构；以能传递动力的方式与所述第一输入轴连接的第一电动机；和以能传递动力的方式与所述第二输入轴连接的第二电动机。所述控制设备包括：控制装置，所述控制装置用于在所述车辆利用所述内燃发动机行驶时将所述第一离合器和所述第二离合器控制成使得所述第一输入轴和所述第二输入轴中的一者以能传递动力的方式与所述内燃发动机连结并且切断所述内燃发动机与所述第一输入轴和所述第二输入轴中的另一者之间的动力传递，所述控制装置当在所述车辆利用所述内燃发动机行驶时加速器踏板被踏压时将所述第一变速机构和所述第二变速机构之中控制所述输出系统与所述第一输入轴和所述第二输入轴中的所述另一者之间的动力传递的一者切换为所述空档状态，并且当在所述车辆利用所述内燃发动机行驶时所述加速器踏板的踏压被解除时将所述第一变速机构和所述第二变速机构中的所述一者切换为所述接合状态以使得所述输出系统与所述第一输入轴和所述第二输入轴中的所述另一者之间的动力传递由具有比正被用于所述内燃发动机与所述输出系统之间的动力传递的齿轮系的变速比大的变速比的齿轮系建立。
对于上述控制设备，当在车辆利用内燃发动机行驶时加速器踏板被踏压时，控制输出系统与第一输入轴和第二输入轴中的所述另一者之间的动力传递的一个变速机构切换为空档状态，因此能使第一输入轴和第二输入轴中的所述另一者与内燃发动机和输出系统分离。因而，能防止与第一输入轴和第二输入轴中的所述另一者连接的电动机的共同旋转，因此能防止内燃发动机的动力的不经济消耗。因而，能提高内燃发动机的燃料经济性。另一方面，当加速器踏板的踏压被解除时，所述一个变速机构切换为接合状态以使得输出系统与第一输入轴和第二输入轴中的所述另一者之间的动力传递由具有比此时正被用于动力传递的齿轮系的变速比大的变速比的齿轮系——也就是位于低速档侧的齿轮系——建立。因此，当制动踏板被踏压时，能仅通过切换第一离合器的状态和第二离合器的状态来降档。因而，能在减速时快速降档。此外，通过这样快速降档，能快速实现比降档之前的发动机制动更强的发动机制动。
上述控制设备还可包括车速判定装置，所述车速判定装置用于判定在制动踏板被踏压时所述车辆的速度是否处于有必要进行降档以从当前档位切换为比当前档位低的档位的预定降档范围内，其中所述控制装置可构造成，当在所述车辆利用所述内燃发动机行驶时所述车速判定装置判定为所述车辆的速度处于所述降档范围内且所述加速器踏板的踏压被解除时，将所述第一变速机构和所述第二变速机构中的所述一者切换为所述接合状态以使得所述输出系统与所述第一输入轴和所述第二输入轴中的所述另一者之间的动力传递由具有比正被用于所述内燃发动机与所述输出系统之间的动力传递的齿轮系的变速比大的变速比的齿轮系建立。这种情况下，当车辆的速度(车速)处于降档范围之外时，即使当加速器踏板的踏压被解除时，所述一个变速机构也维持在空档状态下。因此，能进一步抑制内燃发动机的动力消耗，因此能进一步提高燃料经济性。
如上所述，对于上述控制设备，当加速器踏板被踏压时，控制输出系统与第一输入轴和第二输入轴中的所述另一者之间的动力传递的一个变速机构切换为空档状态。因而，能提高内燃发动机的燃料经济性。另一方面，当加速器踏板的踏压被解除时，所述一个变速机构切换为接合状态以使得输出系统与第一输入轴和第二输入轴中的所述另一者之间的动力传递由位于低速档侧的齿轮系建立。因此，能在减速时快速降档。
附图说明
下面将参照附图说明本发明的示例性实施例的特征、优点以及技术和工业意义，在附图中相似的附图标记表示相似的要素，并且其中：
图1是示出了根据本发明一个实施例的控制设备组装在其上的车辆的示意图；
图2是示出了变速线图的一个示例的视图；以及
图3是示出了由车辆控制设备执行的换档前控制例程的流程图。
具体实施方式
图1示意性地示出了根据本发明一个实施例的控制设备组装在其上的车辆。车辆1包括内燃发动机(在下文中称为发动机)2、第一电动发电机(在下文中简称为第一MG)3和第二电动发电机(在下文中简称为第二MG)4。发动机2用作行驶用电力源。第一MG 3用作第一电动机。第二MG 4用作第二电动机。亦即，车辆1被构造为混合动力车辆。发动机2是具有多个(在图1中为四个)气缸的公知的火花点火式内燃发动机。此外，第一MG 3和第二MG 4各自被已知为装设在混合动力车辆上并且均起到电动机和发电机两种作用。因此，省略了对它们的详细说明。
在车辆1上装设有变速器10。变速器10能够在多个档位(1档至5档和倒档)之间变速。变速器10为双离合器变速器。变速器10包括输入系统11和输出系统12。输入系统11包括第一输入轴13和第二输入轴14。第一输入轴13经由第一离合器15与发动机2连接。第二输入轴14经由第二离合器16与发动机2连接。第一离合器15和第二离合器16各自为能够在接合状态与分离状态之间切换的公知的摩擦离合器。在接合状态下，在发动机2与输入轴13、14中的对应一者之间传递动力。在分离状态下，该动力传递被切断。
输出系统12包括第一输出轴17、第二输出轴18和驱动轴19。如图所示，在第一输出轴17上设置有第一输出齿轮20。在第二输出轴18上设置有第二输出齿轮21。在驱动轴19上设置有被驱动齿轮(从动齿轮)22。第一输出齿轮20和第二输出齿轮21各自与被驱动齿轮22啮合。驱动轴19以能传递动力的方式与差动机构5连接。差动机构5是向左右驱动轮6分配输入动力的公知的机构。
第一至第五齿轮系G1至G5和倒档齿轮系GR介设在输入系统11与输出系统12之间。如图所示，第一齿轮系G1、第三齿轮系G3和第五齿轮系G5介设在第一输入轴13与第一输出轴17之间。第二齿轮系G2、第四齿轮系G4和倒档齿轮系GR介设在第二输入轴14与第二输出轴18之间。
第一齿轮系G1由相互啮合的第一驱动齿轮23和第一被驱动齿轮24构成。第二齿轮系G2由相互啮合的第二驱动齿轮25和第二被驱动齿轮26构成。第三齿轮系G3由相互啮合的第三驱动齿轮27和第三被驱动齿轮28构成。第四齿轮系G4由相互啮合的第四驱动齿轮29和第四被驱动齿轮30构成。第五齿轮系G5由相互啮合的第五驱动齿轮31和第五被驱动齿轮32构成。第一至第五齿轮系G1至G5各自设置成使得驱动齿轮和被驱动齿轮彼此常啮合。对齿轮系G1至G5分别设定相互不同的变速比。变速比以第一齿轮系G1、第二齿轮系G2、第三齿轮系G3、第四齿轮系G4和第五齿轮系G5的次序变得越来越小。倒档齿轮系GR由倒档驱动齿轮33、中间齿轮34和倒档被驱动齿轮35构成。
第一驱动齿轮23、第三驱动齿轮27和第五驱动齿轮31在第一输入轴13上被固定成与第一输入轴13一体地旋转。另一方面，第一被驱动齿轮24、第三被驱动齿轮28和第五被驱动齿轮32由第一输出轴17支承成可相对于第一输出轴17旋转。第二驱动齿轮25、第四驱动齿轮29和倒档驱动齿轮33在第二输入轴14上被固定成与第二输入轴14一体地旋转。另一方面，第二被驱动齿轮26、第四被驱动齿轮30和倒档被驱动齿轮35由第二输出轴18支承成可相对于第二输出轴18旋转。中间齿轮34由变速器10的外壳(未示出)可旋转地支承。如图所示，中间齿轮34与倒档驱动齿轮33和倒档被驱动齿轮35各自啮合。
在第一输出轴17上设置有第一套筒36、第三套筒38和第五套筒40。这些套筒36、38、40由第一输出轴17支承成与第一输出轴17一体地旋转并且可沿轴线方向移动。第一套筒36设置成可在接合位置与释放位置之间切换。在接合位置，第一套筒36与第一被驱动齿轮24啮合成使得第一输出轴17和第一被驱动齿轮24彼此一体地旋转。在释放位置，该啮合被解除。第三套筒38设置成可在接合位置与释放位置之间切换。在接合位置，第三套筒38与第三被驱动齿轮28啮合成使得第一输出轴17和第三被驱动齿轮28彼此一体地旋转。在释放位置，该啮合被解除。第五套筒40设置成可在接合位置与释放位置之间切换。在接合位置，第五套筒40与第五被驱动齿轮32啮合成使得第一输出轴17和第五被驱动齿轮32彼此一体地旋转。在释放位置，该啮合被解除。在下文中，第一套筒36、第三套筒38和第五套筒40全都切换到释放位置的情形可称为空档状态。通过这样控制第一输出轴17与各被驱动齿轮24、28、32之间的动力传递，第一套筒36、第三套筒38和第五套筒40起到根据本发明的第一变速机构的作用。第一套筒36切换到接合位置的情形、第三套筒38切换到接合位置的情形或第五套筒40切换到接合位置的情形起到根据本发明的接合状态的作用。
在第二输出轴18上设置有第二套筒37、第四套筒39和倒档套筒41。这些套筒37、39、41由第二输出轴18支承成与第二输出轴18一体地旋转并且可沿轴线方向移动。第二套筒37设置成可在接合位置与释放位置之间切换。在接合位置，第二套筒37与第二被驱动齿轮26啮合成使得第二输出轴18和第二被驱动齿轮26彼此一体地旋转。在分离状态下，该啮合被解除。第四套筒39设置成可在接合位置与释放位置之间切换。在接合位置，第四套筒39与第四被驱动齿轮30啮合成使得第二输出轴18和第四被驱动齿轮30彼此一体地旋转。在释放位置，该啮合被解除。倒档套筒41设置成可在接合位置与释放位置之间切换。在接合位置，倒档套筒41与倒档被驱动齿轮35啮合成使得第二输出轴18和倒档被驱动齿轮35彼此一体地旋转。在释放位置，该啮合被解除。在下文中，第二套筒37、第四套筒39和倒档套筒41全都切换到释放位置的情形可称为空档状态。通过控制第二输出轴18与各被驱动齿轮26、30、35之间的动力传递，第二套筒37、第四套筒39和倒档套筒41起到根据本发明的第二变速机构的作用。第二套筒37切换到接合位置的情形、第四套筒39切换到接合位置的情形或倒档套筒41切换到接合位置的情形起到根据本发明的接合状态的作用。
尽管在图中未示出，但对输出轴17、18上的各被驱动齿轮设置用于使各套筒36至41与对应的一个被驱动齿轮24、26、28、30、32、35啮合时的旋转同步的同步机构。这些同步机构均可以是用于通过摩擦结合来使旋转同步的同步机构和例如公知的键式同步啮合机构。因此，省略了对各同步机构的详细说明。
在第一输入轴13上设置有第一被驱动齿轮42。在第一MG 3的输出轴3上设置有与第一被驱动齿轮42啮合的第一驱动齿轮43。因而，第一MG 3以能传递动力的方式与第一输入轴13连接。第一驱动齿轮43与第一被驱动齿轮42之间的变速比被设定成使得第一MG 3的旋转减速并且然后传递到第一输入轴13。在第二输入轴14上设置有第二被驱动齿轮44。在第二MG 4的输出轴4a上设置有与第二被驱动齿轮44啮合的第二驱动齿轮45。因而，第二MG 4以能传递动力的方式与第二输入轴14连接。第二驱动齿轮45与第二被驱动齿轮44之间的变速比被设定成使得第二MG 4和第二输入轴14以基本上相同的旋转速度旋转。这样，第一驱动齿轮43与第二被驱动齿轮42之间的变速比和第二驱动齿轮45和第二被驱动齿轮44之间的变速比被设定成彼此不同。
第一离合器15、第二离合器16和套筒36至41的操作由车辆控制设备50控制。此外，发动机2、第一MG 3和第二MG 4的操作也由车辆控制设备50控制。车辆控制设备50被构造成包括微处理器和诸如RAM和ROM之类的周边设备的计算机单元。需要周边设备来操作微处理器。车辆控制设备50保持用于适当地使车辆1行驶的各种控制程序。车辆控制设备50通过执行这些程序来控制受控对象，例如发动机2和MG 3、4。各种用于获取与车辆1有关的信息的传感器与车辆控制设备50连接。例如，车速传感器51、加速器操作量传感器52等与车辆控制设备50连接。车速传感器51输出与车辆1的速度(车速)对应的信号。加速器操作量传感器52输出与加速器踏板的踏压量(也就是加速器操作量)对应的信号。此外，变速杆(未示出)也与车辆控制设备50连接。除上述外，各种传感器、开关等与车辆控制设备50连接；然而，省略了它们的图示。
车辆控制设备50基于车速和加速器操作量来改变变速器10的档位。车辆控制设备50的ROM存储表示车速、加速器操作量和档位之间的关系的变速线图，其一个示例在图2中示出。车辆控制设备50基于该变速线图以车辆1的当前行驶状态为依据来设定档位。套筒36至41的操作被控制成使得变速器10切换到所设定的档位。
车辆控制设备50基于车速等来切换车辆1的行驶用动力源。车辆控制设备50在车速低于预定的判定速度时利用第一MG 3或第二MG 4来驱动驱动轮6，而在车速高于或等于该判定速度时主要利用发动机2来驱动驱动轮6。当利用发动机2来驱动驱动轮6时，可通过第一MG 3或第二MG4来辅助驱动。当利用第一MG 3或第二MG 4来驱动驱动轮6时，第一离合器15和第二离合器16两者都切换到分离状态。利用与具有按照上述设定方法设定的档位的输入轴相关的MG来驱动驱动轮6。当利用发动机2来驱动驱动轮6时，第一离合器15和第二离合器16中与具有按照上述设定方法设定的档位的输入轴相关的一者切换到接合状态，而另一个离合器切换到分离状态。因而，发动机2的动力传递到驱动轮6。
车辆控制设备50在利用发动机2驱动驱动轮6时(换言之，在车辆1利用发动机2行驶时)将与动力传递不相关的输入轴上的套筒全都切换到释放位置。例如，当档位为3档并且第一输入轴13与动力传递相关时，第二输入轴14上的第二套筒37、第四套筒39和倒档套筒41全都切换到释放位置。然而，当加速器踏板的踏压被解除时，也就是当加速器关闭时，与动力传递不相关的输入轴上的套筒之中具有比当前档位大的变速比的档位的套筒、也就是档位较低的套筒切换到接合位置。例如，当加速器在档位为3档时关闭时，第二套筒37切换到接合位置。
图3示出了由车辆控制设备50执行以便这样控制套筒36至41的操作的换档前控制例程。该控制例程在车辆1行驶时以预定间隔反复执行。通过执行该控制例程，车辆控制设备50起到根据本发明的控制装置的作用。
在该控制例程中，车辆控制设备50首先在步骤S11中获取车辆1的状态。例如，获取车速、加速器操作量等作为车辆1的状态。在接下来的步骤S12中，车辆控制设备50判定发动机2是否停止。当判定为发动机2停止时，结束当前控制例程。
另一方面，当判定为发动机2处于运转中时，处理进行到步骤S13，并且车辆控制设备50判定当前车速是否处于在制动踏板被踏压的情况下需要降档的任何一个降档范围内。通过参照图2所示的变速线图来执行该判定。该图中的阴影线范围A1至A4被设定为降档范围。如从该曲线图明显可见，由各变速线L1至L4和通过对相应一个变速线L1至L4增加预定值而获得的速度围绕的预定范围被设定为降档范围。例如，当当前档位为3档时，车辆控制设备50判定车速是否处于降档范围A2内。通过执行该处理，车辆控制设备50起到根据本发明的车速判定装置的作用。
当判定为车速处于任何一个降档范围内时，处理进行到步骤S14，并且车辆控制设备50判定加速器是否关闭，也就是加速器踏板的踏压是否被解除。当判定为加速器关闭时，处理进行到步骤S15，并且车辆控制设备50执行换档前控制。在换档前控制中，如上所述，与动力传递不相关的输入轴上的套筒之中具有比当前档位大的变速比的档位的套筒切换到接合位置。例如，当当前档位为3档时，第二套筒37切换到接合位置。当既定套筒已经切换到接合位置时，维持该状态。此后，结束当前控制例程。
另一方面，当判定为车速处于降档范围之外或者当判定为加速器未关闭、也就是加速器踏板被踏压时，处理进行到步骤S16，并且车辆控制设备50执行空档控制。在空档控制中，如上所述，与动力传递不相关的输入轴上的套筒全都切换到释放位置。当既定套筒已经切换到释放位置时，维持该状态。此后，结束当前控制例程。
如上所述，在本发明中，当车辆利用发动机2行驶并且加速器踏板未被踏压时，与动力传递不相关的输入轴上的套筒全都切换到释放位置。因此，能将与动力传递不相关的输入轴与发动机2和输出系统12分离。这种情况下，能防止与输入轴连接的MG的共同旋转，因此能防止发动机2的动力的不经济消耗。因而，能提高发动机2的燃料经济性。
另一方面，在车辆利用发动机2行驶的情况下，当判定为车速处于任何一个降档范围内并且加速器关闭时，与动力传递不相关的输入轴上的套筒之中具有比当前档位大的变速比的档位的套筒切换到接合位置。因此，当制动踏板此后被踏压时，能仅通过切换第一离合器15的状态和第二离合器16的状态来执行换档。因而，能快速降档。此外，通过这样快速降档，能快速实现比降档之前的发动机制动更强的发动机制动。
执行换档前控制的条件不限于判定为车速处于任何一个降档范围内且加速器关闭的情形。当加速器在车速处于降档范围之外时关闭时，可执行换档前控制。
本发明不限于上述实施例，并且可采用各种形式来实施。例如，在上述实施例中，输入轴和电动发电机以能传递动力的方式分别经由齿轮连接；相反，电动发电机的输出轴可与对应的输入轴直接连接。本发明所应用的混合动力车辆的变速器不限于前进5档变速器，并且可以是前进4档变速器或前进6档或6档以上的变速器。
