Description

用于运行机动车的方法和控制器
技术领域
本发明涉及一种用于运行机动车的传动系的方法。此外，本发明还涉及一种用于执行该方法的控制器。
背景技术
混合动力车辆的驱动机组包括内燃发动机和电机。燃料在内燃发动机中燃烧，以便经由内燃发动机向混合动力车辆的输出装置提供驱动功率。而电机将存储在混合动力车辆的被构造为牵引电池的电能存储器中的电能转换成用于输出装置的驱动功率。在驱动机组与输出装置之间接连有传动机构。传动机构转换转速和转矩，并且因此将驱动机组的牵引力供应施予给输出装置。在电机发动机式运行中，电能存储器较大程度地放电。在电机发电机式运行中，电能存储器较大程度地充电。电能存储器在此以如下方式进行放电和充电：使得电能存储器的荷电状态在下限值与上限值之间运动，以便确保针对电能存储器的尽可能长的使用寿命。
由实践所公知的混合动力车辆还具有排气后处理***。这种排气后处理***在此典型地具有颗粒过滤器。在颗粒过滤器中从废气中过滤出颗粒、如烟灰颗粒。在此重要的是，要不时地再生颗粒过滤器，以便可以尽可能有效地从废气中去除颗粒。因此，可以以由实践所公知的方式和方法来获知颗粒过滤器的当前的负载状态。如果当前的负载状态大于负载极限或达到该负载极限，则可以识别到颗粒过滤器的再生需求，并且随后让该颗粒过滤器经历再生。
但是，颗粒过滤器的再生需求也可以以其他方式和方法来获知，例如依赖于时间地、依赖于运行小时地或依赖于行驶里程地来获知。
由实践所公知的是，提高废气温度来让颗粒过滤器再生。通过提高废气温度，可以在颗粒过滤器中燃烧颗粒，以便因此降低颗粒过滤器的负载状态。
由DE 10 2016 200 972 A1公知有一种用于运行机动车的传动系的方法，其中，只有当内燃发动机在有利于再生的运行范围内工作时，才执行对排气后处理***的颗粒过滤器的再生。位于有利的运行范围之外的内燃发动机的运行点在执行再生时通过将电机作为发电机运行或作为发动机运行来改变到有利的运行范围中。即使当在没有改变的情况下出现的运行点已经处于有利的工作范围内时，运行范围也被改变。电机的运行在此以这样的方式进行，即，使得电能存储器的荷电状态相应于针对电能存储器的荷电状态的下限值与上限值之间的中间的目标值。
要求在于，机动车在颗粒过滤器的再生期间特别有效地运行。
发明内容
基于此，本发明的任务是：提供机动车的传动系的新颖的方法和控制器。
该任务通过根据权利要求1的用于运行机动车的传动系的方法来解决。
根据本发明，当识别到颗粒过滤器的再生需求时，为了准备让颗粒过滤器再生，通过发动机式地运行电机让电能存储器放电直到下限值之下的荷电状态。
随后，为了再生颗粒过滤器，让内燃发动机在限定的运行点中运行以用于在提高由内燃发动机提供的转矩的情况下提高废气温度，并且让电机发电机式地运行，其中，在此由电机产生的电能用于给电能存储器充电，并且/或者用于运行机动车的至少一个副耗电器。
由本发明首次提出的是，当识别到颗粒过滤器的再生需求时，将传动系准备用于对颗粒过滤器再生，更确切地说通过如下方式来进行，即，通过发动机式地运行电机让电能存储器放电直到下限值之下的荷电状态。在该准备工作之后才进行对排气后处理***的颗粒过滤器的实际再生。
为了让颗粒过滤器进行实际再生，然后让内燃发动机在限定的运行点中运行，用以在提升由内燃发动机提供的转矩的情况下提高废气温度。此外，与此同时让与内燃发动机联接的或与内燃发动机作用连接的电机发电机式地运行。在此由电机产生的电能用于给电能存储器充电，并且/或者用于运行机动车的至少一个副耗电器。由此，在排气后处理***的颗粒过滤器再生期间，使得机动车可以特别有效地运行。
根据一个有利的改进方案，在微粒过滤器再生期间，电能存储器被充电直到上限值之上的荷电状态。由此，在排气后处理***的颗粒过滤器再生期间，使得机动车的运动的效率可以更进一步提高。
优选地，当机动车具有至少一个副耗电器时，在颗粒过滤器再生期间由电机产生的电能优先用于让至少一个副耗电器在其允许的运行极限内运行，其中，额外产生的电能用于给电能存储器充电。本发明的这个方面基于如下认知，对于具有至少一个副耗电器的机动车而言有利的是，在颗粒过滤器再生期间使用由电机产生的电能首先直接用于运行机动车的至少一个副耗电器，也就是没有中间转换成存储在电能存储器中的电能。副耗电器可以是例如DCDC转换器、PTO驱动器、机动车的压缩空气***的空气压缩机的电动马达和/或机动车的空调***的或制冷***的空调压缩机的电动马达。
优选地，在机动车静止不动时执行颗粒过滤器的再生，其中，为此，驱动机组与输出装置脱联，并且由内燃发动机产生的转矩被发电机式运行的电机所取走。在机动车静止不动时，颗粒过滤器的再生可以特别有利地进行。
根据本发明的控制器在权利要求8中限定。
附图说明
优选的改进方案由从属权利要求和以下描述得出。结合附图更详细地阐述本发明的实施例，但不限于此。其中：
图1示出用于清楚说明本发明的机动车的传动系的框图。
具体实施方式
图1示出了机动车的传动系1的框图。传动系1包括具有内燃发动机3和电机4的驱动机组2。电机4与电能存储器5协同作用，该电能存储器也被称为牵引电池。
燃料在内燃发动机3中燃烧，以便提供驱动功率。当在电能存储器5较大程度上放电的情况下电机4发动机式地运行时，于是可以由电机4提供驱动功率。然而，在电机4发电机式地运行中，电能存储器5较大程度上被充电。
在传动系1的驱动机组2与输出装置6之间接有传动机构7。传动机构7转换转速和转矩，并且因此在输出装置6上提供了驱动机组2的牵引力供应。传动机构7优选是自动化的换挡传动机构或者是具有多个切换元件的自动的换挡传动机构，切换元件可以被实施为摩擦锁合(reibschlüssig)的切换元件和/或形状锁合(formschlüssig)的切换元件。此外，图1还示出了可选的分离离合器8，其被接在内燃发动机3与电机4之间。
内燃发动机3的运行由发动机控制器9控制和/或调节。传动机构7的运行由传动机构控制器10控制和/或调节。电机4和电能存储器5的运行由混合动力控制器11控制和/或调节，其中，混合动力控制器11也可以是传动机构控制器10的被整合的组成部分。根据图1的双虚线箭头，发动机控制器9与内燃发动机3、传动机构控制器10与传动机构7以及混合动力控制器11与电机4和电能存储器5交换数据。此外，控制器9、10和11还彼此交换数据。
图1的机动车还包括排气后处理***12。根据图1的点划线的箭头，在内燃发动机3中燃烧燃料时所产生的废气被输送给排气后处理***12以进行排气后处理。这种排气后处理***12可以包括不同的部件。排气后处理***12包括至少一个颗粒过滤器13，经由该颗粒过滤器可以将诸如烟灰颗粒的颗粒从废气过滤掉。排气后处理***12可以包括催化净化器作为另外的部件。催化净化器可以前置于或后置于颗粒过滤器13。在将内燃发动机3实施为柴油发动机的机动车中，催化净化器典型地实施为SCR催化净化器。在这种情况下，于是排气后处理***12包括作为另外的结构组件的装置，借助该装置可以将氨或氨前体物质
Figure BDA0002387084420000051
引入到SCR催化净化器的上游的废气中。
排气后处理***12的颗粒过滤器13用于从内燃发动机3的废气中滤出颗粒。颗粒过滤器13的有效性在此依赖于具有颗粒的颗粒过滤器所谓的负载状态。如果负载状态达到或超过负载极限，则存在颗粒过滤器13的再生需求，其中，于是随后可以让其经历再生。颗粒过滤器13的再生需求可以由排气后处理***12以本领域技术人员所公知的方式来获知并作为输入变量例如提供给发动机控制器9。
如上已实施地，驱动机组2的电机4可以发动机式地以及发电机式地运行。在电机4处于发动机式的运行中时，电能存储器5较大程度地放电，而当电机4处于发电机式的运行中时，电能存储器较大程度地充电。这以如下方式进行，即，使电能存储器5的荷电状态在上限值与下限值之间运动。这尤其用于保护电能存储器5免于快速老化。
当识别到颗粒过滤器13的再生需求时，为了准备让颗粒过滤器13再生，通过发动机式地运行电机4让电能存储器5放电直到该下限值之下的荷电状态。只有在该准备工作之后才进行颗粒过滤器13的实际再生，更确切地说通过如下方式进行，即，让内燃发动机3在限定的运行点中运行以用于在提高由内燃发动机3提供的转矩的情况下提高废气温度。于此同时，让与内燃发动机3联接的电机4发电机式地运行。在电机4的发电机式的运行中所产生的电能用于给电能存储器5充电，并且/或者用于运行机动车的至少一个副电消耗器。
当机动车具有至少一个副耗电器时，则在颗粒过滤器13的再生期间由电机4所产生的电能优先用于让至少一个副耗电器在其允许的运行极限内运行。不是至少一个副耗电器所需的另外的电能然后用于给电能存储器5充电。副耗电器可以是机动车的压缩空气***的空气压缩机的电动马达。另外的副耗电器可以是机动车的空调***的或制冷***的空调压缩机的电动马达。由于在颗粒过滤器13的再生期间所产生的电能优先用于运行这种副消耗器，因此不存在将电能中间存储在电能存储器5中时的损耗。
当传动系不包括副耗电器时，则在颗粒过滤器13再生期间由发电机式地运行的电机4所产生的电能优先用于电能存储器5充电。
在本发明的一个特别有利的实施形式中设置的是，在微粒过滤器13再生期间，电能存储器5被充电直到上限值之上的荷电状态。因此，为了准备再生改变了用于储能器5的荷电状态的下限值，并且在再生期间改变了用于储能器5的荷电状态的上限值，以便使机动车的传动系在再生期间特别有效地运行。
上述方法优选在机动车静止不动的情况下执行。当机动车静止不动时，驱动机组2与输出装置6分离。这可以例如通过如下方式来进行，即，将传动机构7转换到空挡或非力锁合(nicht-kraftschlüssig)的滑行挡(Segelgang)。也可以在驱动机组2与传动机构7之间接有起动离合器，于是为了使驱动机组2与传动机构7脱联而断开该起动离合器。在这种静态再生期间由内燃发动机3所提供的转矩于是仅被发电机式地运行的电机4取走。如已实施地，该电能可以用于给电能存储器5充电并且/或者用于运行至少一个副耗电器。
也可行的是，在机动车行驶期间作为所谓的动态再生来执行颗粒过滤器13。为此，于是将驱动机组2与输出装置6联接。于是，在颗粒过滤器13的再生期间所产生的转矩一方面被发电机式地运行的电机4取走，以及另一方面被输出装置6取走。当在行驶期间进行颗粒过滤器13再生时，与没有进行再生的行驶状态相比，内燃发动机3的负载点提高，更确切地说以如下方式进行，即，在内燃发动机3中燃烧了更多的燃料，并且因此内燃发动机3产生了更大的转矩。该转矩被电机4转换成电能，该电能用于给电能存储器5充电并且/或者用于运行至少一个副耗电器。
本发明还涉及用于执行上述方法的控制器。该控制器可以例如是发动机控制器9。于是，当控制器识别到颗粒过滤器13的再生需求时，控制器准备让颗粒过滤器13再生，更确切地说通过如下方式进行，即，让电机4发动机式地运行，以便将电能存储器5放电直到下限值之下的荷电状态。随后，为了让颗粒过滤器13再生，控制器让内燃发动机3在限定的运行点中运行以用于在提高内燃发动机3所提供的转矩的情况下升高废气温度。与此同时地，控制器让与内燃发动机3耦接的电机4发电机式地运行，然后电机产生电能。电能用于给电能存储器5充电，并且/或者用于运行机动车的至少一个副耗电器。
