混合动力车辆以及用于运行混合动力车辆的方法
技术领域
本发明涉及一种混合动力车辆，其具有在动力传动系中作为驱动设备/驱动机的内燃机式驱动设备和电驱动设备，其中电驱动设备和为电驱动设备配设的高压电池连接到混合动力车辆的高压电网，其中混合动力车辆还具有至少一个带有空调压缩机的空调设施，为该空调压缩机配设用于由高压电网运行空调压缩机的电机。此外，本发明还涉及一种用于运行这种混合动力车辆的方法。
背景技术
混合动力车辆在现有技术中已知，并且其特征在于，混合动力车辆具有至少两个驱动设备，即常见的例如通过油箱的燃料运行的内燃机式驱动设备以及使用在高压电池中存储的电能来运行的电驱动设备。这种电驱动设备通常还以发电机模式运行，以便例如能够为高压电池充电(回收)。混合动力车辆例如能够分为所谓的轻度混合动力车辆和插电式混合动力车辆，在插电式混合动力车辆的情况下可以经由机动车内部充电设备为高压电池充电。
如果在这种混合动力车辆中使用空调压缩机，尤其作为空调设施的组成部分，则这些空调压缩机在传统上可以经由内燃机式驱动设备的皮带传动机构、即间接地经由内燃机式驱动设备运行，或作为与皮带传动机构分离的高压空调压缩机被自身的、由高压电网馈电的电机驱动。在所述第一种情况下，只有在内燃机式驱动设备也运行时，混合动力车辆才可以运行，而在第二种情况下如果高压电池的荷电状态太低，则始终存在问题。尤其还要担心高压电池的大范围放电，这对电力续航是不利的。换句话说，仅在高压电池足够充电的情况下第二变型才允许冷却内部空间。另一方面，尤其在机动车停止时处于怠速的情况下对高压电池的充电是不可能的，这是因为在该时间点电驱动设备通常是解耦的。
因此上述情况仅在内燃机式机运行时或当高压电池为空调压缩机的电机提供足够的功率时，才允许空调压缩机运行。
对于传统的机动车，例如在文献DE 10 2008 036 167 A1中提出一种用于机动车内燃机的附件设备，该附件设备在简单的结构下允许低燃料消耗。这里提出，在空调压缩机和起动发电机之间设置可切换的中间离合装置，利用该中间离合装置可以切断空调压缩机对起动发电机的反作用。此外在起动发电机和内燃机之间设置另一可切换的输入离合装置。文献DE 603 01 516 T2涉及一种车辆空调设施，其中压缩机与用于驱动车辆的电机连接，其中作为对所述电机停止的响应，断开在所述电机和所述压缩机之间的连接，并且作为对所述电机停止的响应，电机与所述压缩机连接以驱动所述压缩机。
发明内容
因此本发明的目的是，提供压缩机在混合动力车辆中改进的连接。
为了实现该目的，在根据本发明的开头所述类型的混合动力车辆中设置，构成附件设备的电机经由第一离合装置与空调压缩机，并且经由第二离合装置与内燃机式驱动设备的皮带传动机构连接，并且能为高压电池充电而运行，其中控制设备被设置用于根据机动车的当前运行状态至少驱控离合装置、尤其是驱控附件设备整体。
因此，构成的附件设备除了电机之外还包括第一离合装置、空调压缩机、第二离合装置和皮带传动机构。根据运行状态的驱控尤其是可以理解为，控制设备使用至少两个具有相应分配有使用标准的运行模式，其中在满足运行模式的使用标准后选择并使用分配的运行模式。使用标准可以评估混合动力车辆的描述机动车运行状态的至少一个运行参数，尤其是动力传动系和/或高压电网的至少一个运行参数、尤其是高压电池的至少一个运行参数、和/或空调设施的至少一个运行参数。尤其是，仅当需要空调压缩机实现期望的、尤其是使用者方面预设的空气调节作用时，才运行空调压缩机。控制设备优选被设计用于驱控附件设备整体，其中控制设备还可以用于驱控机动车的其他部件，例如可以至少部分控制空调设施的运行和/或至少部分控制高压电网以及连接的部件的运行。控制设备为此尤其也可以与机动车的其他控制设备、尤其是控制器通信，以便获得例如高压电网中关于空调压缩机和/或要执行的充电任务的信息。
通过将可以由高压电网运行的空调压缩机连接入内燃机式驱动设备的皮带传动机构，空调压缩机或者可以直接由内燃机式驱动设备运行，或者由高压电池经由电机运行。这意味着，空调压缩机可以理解为混合式空调压缩机。在这种局面下同样可以将空调压缩机电机用作发电机，并且尤其是在混合动力车辆到现在为止有问题的停止或怠速状态下对高压电池再次充电。附件设备相应地具有两个离合装置，即第一离合装置和第二离合装置，该第一离合装置实现电机与空调压缩机耦接，第二离合装置既可以将空调压缩机与皮带传动机构分离，又可以将电机与皮带传动机构分离。因此空调压缩机可以一方面仅与电机耦接以实现纯电气运行，从而仅第一离合装置接合，但第二离合装置断开。但第二离合装置也可以接合，从而空调压缩机由电机和内燃机式驱动设备运行，即，提供所谓补充的转矩。但同样可以设置，如果两个离合装置均接合，则空调压缩机仅经由内燃机式驱动设备运行，其中通过相应的驱控，可以将电机置入尽可能降低其制动作用的状态，即被跨接/桥接的状态。这例如可以通过将电机的绕组切换到高电阻状态来完成。以这种方式，可以将皮带传动机构仅用于运行空调压缩机。但是如还要更详细描述的，在这种两个离合装置接合的运行状态下也可以考虑，通过电机在发电机运行模式下产生功率，并将该功率用于对高压电池充电，从而即便空调压缩机运行，但是在混合动力车辆停止或在内燃机式驱动设备的怠速时也可以对高压电池充电。为了更加高效地实现这一点，可以在不需要空调压缩机时通过断开第一离合装置以及接合第二离合装置将功率全部用于对高压电池充电。
通过本发明，可以在混合动力车辆停止时以特别简单的方式方法仅用一个部件——即空调压缩机的电机——既允许对高压电池充电，也对机动车内部空间进行空气调节，另外也可以由高压电网运行空调压缩机。这比使用其他电机-发电机、多个空调压缩机等的方式成本明显更加低廉。皮带传动机构也可以格外简单地设计，因为最终仅需驱动附件设备，而不需要额外的发电机等。这反过来导致成本节省以及节约安装空间。
总而言之，通过不同的运行模式和相应地驱控附件设备可以示出不同运行状态，而无需其他发电机或内燃机式驱动设备的发电机。在该变型中也可以放弃使用传统空调压缩机。首先以简单集成的方式实现，即使在混合动力车辆停止时，即，当不能通过电驱动设备产生电功率时，也能对高压电池充电，并且即使高压电池处于低的荷电状态，也能运行空调压缩机，以在混合动力车辆的内部空间中产生舒适的温度。这尤其是在混合动力车辆经常停车的情况下，例如在堵车时或在具有交通灯的城市内交通的情况下出发不久后，以及在类似交通情况下是格外有利的。
在具体的设计方案中控制设备可以被设计用于针对如下运行模式驱控离合装置：
-第一运行模式，其中第一离合装置接合，并且第二离合装置断开，从而空调压缩机可以经由电机由高压电网运行，
-至少一个第二运行模式，其中第一离合装置且第二离合装置接合，从而空调压缩机可以通过皮带传动机构运行，以及
-至少一个第三运行模式，其中第一离合装置断开，并且第二离合装置接合，从而高压电池可以在空调压缩机不运行时通过皮带传动机构充电。
尤其是关于至少一个第二运行模式和至少一个第三运行模式，可以考虑不同的具体设计方案，如所看到的，例如通过在至少一个可以称作混合式运行模式的第二运行模式中的至少一个，可以将皮带传动机构获得的功率同时用于对高压电池充电以及用于运行空调压缩机，或者在至少一个第二运行模式中的至少一个中，通过内燃机式驱动设备以及由高压电网运行空调压缩机。类似地适用于至少一个第三运行模式，例如在至少一个第三运行模式中的至少一个中，附件设备的电机不必以发电机模式运行，而是以便例如提供助力(Boost)，也可以支持性地有助于驱动机动车。
适宜地，控制设备可以被设计用于在内燃机不运行时和/或在高压电池的荷电状态超过阈值时使用第一运行模式。相应地，控制设备可以被设计用于在内燃机式驱动设备运行时，尤其在怠速下和/或在混合动力车辆停止时使用至少一个第二运行模式和/或至少一个第三运行模式。在此如上所述在混合动力车辆停止时，至少使用第二运行模式和第三运行模式的为高压电池充电的设计方案，则可以被评价为格外有利的。
如已经提到的，本发明的特别有利的改进方案提出，控制设备设计为用于，在第一离合装置和第二离合装置接合的混合式运行模式中，尤其在至少一个第二运行模式的至少一个中运行附件设备，从而将由皮带传动机构获得的能量同时地既通过电机以发电机模式运行来为高压电池充电，又运行空调压缩机。这也实现了，在混合动力车辆停止时在混合动力车辆中运行空调压缩机以及再次为高压电池充电，如果要实现或保持高压电池的特定荷电状态，即使在机动车经常停止的运行阶段，即电驱动设备不提供发电机功率，这尤其在混合动力车辆没有从电网充电的可能性(所谓的轻度混合动力车辆)时是格外有利的。如所示，另外还可以考虑另一第二运行模式，其中电机和皮带传动机构两者有助于运行空调压缩机，这例如在空调设施的可以被相应确定为机动车运行状态的高负荷状态下是有利的。
此外在本发明的范围中有利的是，控制设备被设计用于，在转矩增强模式下在第二离合装置接合并且尤其是第一离合装置断开时，使电机以马达模式运行来提供用于驱动混合动力车辆的增强转矩。这意味着，由于提出的特殊配置，得出另一有利的可用运行模式，尤其是作为混合动力车辆的至少一个第三运行模式中的至少一个，其中通过空调压缩机的电机允许支持对机动车的驱动，尤其是空调压缩机本身不起阻碍作用。
这里需要注意的是，最后可以任意实施第一离合装置和第二离合装置，尤其是实施为机械离合装置或优选实施为电磁离合装置。例如第一离合装置和/或第二离合装置可以设计为磁粉离合装置和/或摩擦离合装置和/或脉冲控制的摩擦离合装置。离合装置可以证明是格外有利的，其中例如通过施加的电压可以控制滑转率，这是因为可以进行或支持功率分配。
附图说明
本发明的其他优点和细节从下面描述的实施例中并且参照附图得出。
这里示出：
图1示出根据本发明的混合动力车辆的原理图，
图2示出附件设备可能的设计方案的分解视图。
具体实施方式
图1示出根据本发明的混合动力车辆1的原理图。在这里该车辆具有仅概括的动力传动系2，该动力传动系包括作为驱动设备的内燃机式驱动设备3和电驱动设备4。电驱动设备4与高压电网5连接，高压电池6也连接到该高压电网。高压电网5的高压可以大于50V、尤其是大于200V、例如为450V。
此外，机动车1还具有仅示意性示出的、带有空调压缩机8的空调设施7，电机9被配设给该空调压缩机。电机9同样与高压电网5连接，并且可以经由第一离合装置10可选地与空调压缩机8断开。
此外内燃机3还配设有皮带传动机构11，该皮带传动机构可以经由第二离合装置12与电机9和空调压缩机8耦接。皮带传动机构11、第二离合装置12、电机9、第一离合装置10和空调压缩机8构成附件设备13，该附件设备可以被控制单元14控制，其中尤其是在根据混合动力车辆1的运行状态而选择的不同运行模式下，使用第一离合装置10和第二离合装置12的不同状态。
在第一运行模式中，第一离合装置10接合，并且第二离合装置12断开，从而空调压缩机8与电机9耦接，但这些部件不与皮带传动机构11耦接。空调压缩机8可以由高压电网5经由电机9运行。如果需要借助于空调设施7运行空调压缩机8来充分冷却内部空间，而内燃机式驱动设备3不运行，并且高压电池6的荷电状态足够高，则例如可以使用这种第一运行模式。
可以通过控制设备14使用的第二运行模式被定义成，第一离合装置10和第二离合装置12两者都是接合的。这实现了可由不同的第二运行模式描述的各种使用场景。一方面可行的是，其中电机9被切换到相应的、尽量无功率的模式，利用由皮带传动机构11提供的功率来运行空调压缩机8。电机9例如可以被“跨接”。但是在混合动力车辆中在停止的机动车1中存在不能为高压电池6充电的问题，这尤其在混合动力车辆1经常停车的交通情况或运行阶段中会对高压电池6的荷电状态起到负面作用，尤其是在所谓的轻度混合动力车辆方面，其中混合动力车辆1不能在机动车外部充电设备上充电。在这种情况下，如果需要空调压缩机8的运行，则可以有利地将由内燃机式驱动设备3通过皮带传动机构11提供的功率分配到空调压缩机8上和以发电机模式运行的电机9上，从而可以同时运行空调压缩机8并对高压电池6充电。
这里需要注意的是，混合动力车辆1可以具有为了清楚起见未详细示出的低压网络(车载电网)，例如12V，也可以为该车载电网分配电池，即车载电网电池。这种车载电网电池原则上也可以直接或间接经由电机9被充电，其中高压电网5通常经由直流电压转换器与相应的低压电网连接，因此在那里可以进行相应的功率交换。出于这种原因，在根据本发明的混合动力车辆1中不需要发电机。
另一第二运行模式提出，空调压缩机8既由电机9、也由皮带传动机构11运行，这尤其是在空调设施7处于高负荷的情况下会是有利的。
一组第三运行模式的特征在于，第一离合装置10断开，但第二离合装置12接合。在这种情况下空调压缩机8不运行。基本上可以想到第三运行模式的两种具体的设计方案。在第三运行模式的主要设计方案中，电机9以发电机模式运行，以便为高压电网5的高压电池6充电。现在讨论的第二运行模式和第三运行模式尤其在混合动力车辆停止时是有利的，因为不能使用电驱动设备4为高压电池6充电或在高压电网5中提供功率。
另一有利的第三运行模式，即转矩增强模式，也可以在常见的混合动力车辆1的运行模式下，尤其是在混合动力车辆1运动中实现，因为电机9可以用于在马达运行模式下提供转矩，可以使用该转矩经由皮带传动机构11来驱动混合动力车辆1，尤其是用于短时提高驱动功率。
附件设备13的具体设计方案在图2的分解图示中示例性地示出。除了示出了空调压缩机8、第一离合装置10、电机9和在此集成在皮带传动机构11的皮带盘15中的第二离合装置12之外，图2还示出作为其他部件的螺钉16、电磁线圈17和电力电子单元18。
