Description

用来运行用于机动车的混合动力总成系统的方法
技术领域
本发明涉及一种用来运行用于机动车的混合动力总成系统的方法，其中，该混合动力总成系统具有一个内燃机和一个电机作为驱动装置，其中，在该混合动力总成系统中设置有一个平行换档变速器，该平行换档变速器具有一个第一变速器输入轴、一个第二变速器输入轴和一个变速器输出轴，其中，该第一变速器输入轴可通过至少一个第一档位与该变速器输出轴相耦合并且该第二变速器输入轴可通过至少一个第二档位与该变速器输出轴相耦合，其中，该内燃机可通过一个第一离合器与该第一变速器输入轴作用连接并且可通过一个第二离合器与该第二变速器输入轴作用连接，其中，该电机与该第二变速器输入轴处于驱动连接。
背景技术
这种方法已由书籍“7.LuK Kolloquium 11./12.April 2002”(编者：LuKGmbH&Co.)的第252～254页公知。在此，为了启动机动车，首先在第一离合器和第二离合器打开的情况下在第一变速器输入轴上挂入档位“1”并且在第二变速器输入轴上预选择档位“2”。然后将第一离合器闭合，以便借助于内燃机将一个转矩传递给机动车的驱动车轮。附加地借助于电机通过第二变速器输入轴和预选择的档位“2”驱动所述驱动车轮(助推功能)。
作为对此的替换方案，可在第一离合器打开的情况下在第一变速器输入轴上挂入档位“1”并且使第二变速器输入轴的档位处于中性位置中。然后将第一离合器和第二离合器闭合，以便借助于内燃机和电机分别将一个转矩传递给机动车的驱动车轮。电机的力流在此通过第二变速器输入轴、第二离合器、内燃机的驱动轴、第一离合器、第一变速器输入轴和档位1延伸到变速器输出轴上。第二输入轴上的档位的预选择在行驶期间在该换档策略下进行。
在机动车达到了预给定的第一速度之后，内燃机从第一档位转换到档位“2”。为此，第二离合器闭合，而同时第一离合器打开并且机动车继续还被电机驱动。
现在在第一变速器输入轴上预选择档位“3”。在机动车达到了预给定的第二速度之后，内燃机从档位“2”转换到档位“3”。为此，第一离合器闭合，而同时第二离合器打开并且机动车继续通过仍挂入的档位“2”还被电机驱动。
现在在第二变速器输入轴上在第二离合器继续打开的情况下预选择档位“4”。在此，首先将电动机的转矩降低到零，然后使档位“2”处于中性位置中，然后将档位“4”挂入。然后，借助于电机重新产生一个转矩并且将其通过预选择的档位“4”传递给机动车的驱动车轮。
在机动车达到了预给定的第三速度之后，将内燃机从档位“3”转换到档位“4”。为此，将第二离合器闭合，而同时第一离合器打开并且机动车继续还被电机驱动。在机动车继续加速时，以相应的方式从档位“4”换档到档位“5”以及从档位“5”换档到档位“6”。
该方法具有缺点：当在第二变速器输入轴上变换档位时，即当从档位“2”转换到档位“4”以及从档位“4”转换到档位“6”时，没有转矩可由电机传递给驱动车轮，因为于是通过第二档位形成的子变速器短暂地处于中性位置中。随之而来的拉力损失被机动车使用者感觉为缺点。
发明内容
因此，本发明的任务在于，提供一种开头所述类型的方法，在该方法中，在电机事先接通的情况下在一个第二档位换档期间在很大程度上避免拉力损失。
该任务通过一种用来运行用于机动车的混合动力总成系统的方法来解决，其中，混合动力总成系统具有一个内燃机和一个电机作为驱动装置，其中，在混合动力总成系统中设置有一个平行换档变速器，该平行换档变速器具有一个第一变速器输入轴、一个第二变速器输入轴和一个变速器输出轴，其中，第一变速器输入轴可通过至少一个第一档位与变速器输出轴相耦合并且第二变速器输入轴可通过至少两个第二档位与变速器输出轴相耦合，其中，内燃机可通过一个第一离合器与第一变速器输入轴作用连接并且可通过一个第二离合器与第二变速器输入轴作用连接，其中，电机与第二变速器输入轴处于驱动连接，
-其中，将一个第一档位挂入并且借助于内燃机通过第一离合器将一个转矩施加给第一变速器输入轴，
-其中，在第二离合器打开的情况下将第一个第二档位挂入并且借助于电机通过第一变速器输入轴和第一个第二档位将一个转矩施加给变速器输出轴，
-其中，在第一离合器上建立离合器滑转，其方式是降低由第一离合器传递的转矩，而提高由电机施加的转矩，
-其中，此后将由电机施加的转矩大致降低到零并且将第二个第二档位挂入，而降低第一离合器上的滑转，其方式是提高通过第一离合器传递的转矩，以及
-其中，此后借助于电机通过第一变速器输入轴和第二个第二档位将一个转矩传递给变速器输出轴。
因此，在开始变换档位之前，通过第一离合器传递的转矩通过部分地打开第一离合器而降低。在此，内燃机的转速稍微上升，由此，附加的动能储存在内燃机中。通过第一离合器传递给变速器输出轴的总转矩的降低通过相应地提高电机的转矩来补偿。由此，尽管第一离合器的离合器力矩降低，机动车的加速也可大致保持恒定。一旦存在足够的滑转裕量(Schlupfreserve)，电机的转矩就降低到零。该降低通过相应地提高通过第一离合器传递的转矩来补偿。在此，第一离合器上的滑转降低。由此，尽管不存在电机的驱动力矩，机动车的加速也可保持恒定。在第二个第二档位挂入并且同步之后，借助于电机又将一个转矩传递给变速器输出轴。通过第一离合器以及必要时第二离合器由内燃机传递给变速器输出轴的转矩相应地降低。由此，在混合动力总成系统的助推工况中在换档过程期间保持无中断的完全的拉力。
此外，上述任务通过一种用来运行用于机动车的混合动力总成系统的方法来解决，其中，混合动力总成系统具有一个内燃机和一个电机作为驱动装置，其中，在混合动力总成系统中设置有一个平行换档变速器，该平行换档变速器具有一个第一变速器输入轴、一个第二变速器输入轴和一个变速器输出轴，其中，第一变速器输入轴可通过至少一个第一档位与变速器输出轴相耦合并且第二变速器输入轴可通过至少一个第二档位与变速器输出轴相耦合，其中，内燃机可通过一个第一离合器与第一变速器输入轴作用连接并且可通过一个第二离合器与第二变速器输入轴作用连接，其中，电机与第二变速器输入轴处于驱动连接，
-其中，将一个第一档位挂入并且借助于内燃机通过第一离合器将一个转矩施加给第一变速器输入轴，
-其中，在至少一个第二档位处于中性位置中时借助于电机通过第二变速器输入轴、第二离合器和第一离合器将一个转矩施加给第一变速器输入轴，
-其中，在第一离合器上建立离合器滑转，而提高由电机施加的转矩，
-其中，在第一离合器上建立离合器滑转，其方式是提高由电机施加的转矩，
-其中，此后降低第一离合器上的滑转，其方式是降低由电机施加的转矩，打开第二离合器并且挂入一个第二档位，以及
-其中，借助于电机通过第一变速器输入轴和第二档位将一个转矩传递给变速器输出轴。
通过电机产生的转矩也可通过第二离合器传递给内燃机并且从该内燃机通过第一离合器传递给第一变速器输入轴和变速器输出轴。在该解决方案中也可在变换档位之前在第一离合器上建立滑转，其方式是将由电机产生的转矩提高。一存在足够的滑转裕量，电机的转矩就降低，由此，第一离合器上的滑转减弱。在第二档位挂入并且同步之后，借助于电机又将一个转矩传递给变速器输出轴。由此，在该解决方案中在换档过程期间也保持无中断的完全的拉力。
有利的是，使电机的转矩这样地与第一离合器的离合器滑转相适配，使得通过第一离合器传递的转矩在离合器滑转的建立期间大致保持恒定。机动车于是仍可较均匀地加速。
优选这样地降低第一离合器的滑转，使得传递给变速器输出轴的转矩从由电机施加的转矩的降低开始直到第二离合器结束闭合大致保持恒定。通过该措施也可在换档过程期间实现机动车均匀地加速。
有利的是，将电机的转矩斜坡状地提高/或降低。第一离合器中的滑转于是可均匀地建立和减弱。

具体实施方式
用于机动车的在图1中用1标记的混合动力总成系统作为驱动装置具有一个内燃机2和一个电机3，该内燃机和该电机通过一个平行换档变速器与机动车的附图中未详细示出的驱动车轮相连接。
平行换档变速器具有一个第一变速器输入轴4a，该第一变速器输入轴可通过一个第一离合器5a与驱动轴6、例如内燃机2的曲轴相连接。平行换档变速器的第二变速器输入轴4b可通过一个第二离合器5b与驱动轴6相连接。此外，电机3与第二变速器输入轴4b处于驱动连接。电机3可相对于第二变速器输入轴4b同轴心地设置或者与该第二变速器输入轴侧向间隔开并且通过一个链或类似传递装置与第二变速器输入轴4b相连接。
给第一变速器输入轴4a配置第一奇数档位1、3和5以及倒车档位。这些档位中的每一个各具有一个可借助于同步装置8无相对转动地与第二变速器输入轴4a相连接并且可与该第二变速器输入轴分开的变速器齿轮7a。档位1、3和5的变速器齿轮7a分别与一个与其相适配的、无相对转动地与变速器输出轴9相连接的齿轮10啮合。
给第二变速器输入轴4b配置第二偶数档位2、4和6。这些档位中的每一个各具有一个可借助于一个同步装置8无相对转动地与第一变速器输入轴4a相连接并且可与该第一变速器输入轴分开的变速器齿轮7a。档位1、3和5的变速器齿轮7b分别与一个与其相适配的、无相对转动地与变速器输出轴9相连接的齿轮10啮合。
在第一换档策略中，为了启动机动车，首先打开两个离合器5a、5b。在第一变速器输入轴4a上挂入档位“1”并且在第二变速器输入轴4b上预选择档位“2”。然后将第一离合器5a闭合，以便借助于内燃机2将一个转矩传递给第一变速器输入轴4a并且从该第一变速器输入轴通过档位“1”传递给变速器输出轴9。附加地借助于电机3产生一个转矩并且将其通过第二变速器输入轴4a和预选择的档位“2”传递给变速器输出轴9(助推功能)。
在机动车达到了预给定的第一速度之后，内燃机2从档位“1”转换到档位“2”。为此，第二离合器5b闭合，而同时第一离合器5a打开并且机动车继续还被电机驱动。
现在在第一变速器输入轴4a上预选择档位“3”。在机动车达到了预给定的第二速度之后，内燃机2从档位“2”转换到档位“3”。为此，第一离合器4a闭合，而同时第二离合器5b打开并且机动车继续通过仍挂入的档位“2”还被电机3驱动。
机动车一旦达到预给定的第三速度，第一离合器5a就稍微打开，以便产生滑转并且降低通过第一离合器5a传递的转矩11。在图3中可看到，通过降低转矩，内燃机2的转速12稍微上升。同时，由电机3施加的转矩13相应地提高，由此，总地传递给变速器输出轴9的转矩14大致保持恒定(参见图2至图4)。内燃机2的转矩在图3中用15标记。
在建立了足够的滑转之后，由电机3施加的转矩13斜坡状地降低，同时，通过第一离合器5a传递的转矩11提高，由此，第一离合器5a上的滑转降低。在图4可看到，内燃机2的转速12在此稍微下降。
在电机3的转矩12降低到零附近的值之后，在第二变速器输入轴4b上预选择档位“4”并且使其同步。在此，第二变速器输入轴4b的转速16下降。此后，借助于电机3重新产生一个转矩13并且将其通过第二变速器输入轴4a和预选择的档位“4”传递给变速器输出轴9。电机3的转矩13斜坡状地提高，而同时通过第一离合器5a传递的转矩11通过第一离合器5a的打开相应地降低，由此，总地传递给变速器输出轴9的转矩14大致保持恒定。第一变速器输入轴4a的转速在图4中用17标记。
机动车一旦达到预给定的第四速度，第一离合器5a就打开并且第二离合器5b闭合，由此，内燃机2于是通过第二离合器5b、第二变速器输入轴4b和档位“4”驱动变速器输出轴9。
在第二换档策略中，为了启动机动车，首先打开两个离合器5a、5b。在第一变速器输入轴4a上挂入档位“1”并且使第二变速器输入轴4b的档位“2”、“4”和“6”处于中性位置中。然后将第一离合器5a和第二离合器5b闭合，以便借助于内燃机2和电机3分别将一个转矩传递给机动车的驱动车轮。电机3的力流在此通过第二变速器输入轴4b、第二离合器5b、内燃机2的驱动轴6、第一离合器5a、第一变速器输入轴4a和档位“1”延伸到变速器输出轴9上。在行驶期间，电机3的转矩降低到零，第二离合器5b打开，以便此后在第二输入轴4b上预选择档位“2”。
在机动车达到了预给定的第一速度之后，内燃机2从档位“1”转换到档位“2”。为此，第二离合器5b闭合，而同时第一离合器5a打开。
