运行机动车混合动力驱动设备的方法及混合动力驱动设备
技术领域
本发明涉及一种用于运行机动车的混合动力驱动设备的方法，其中，混合动力驱动设备具有驱动机组以及电机，所述驱动机组和电机在机动车的行驶运行期间通过变速器与混合动力驱动设备的从动轴有效连接。本发明还涉及一种混合动力驱动设备。
背景技术
混合动力驱动设备用于驱动机动车，因此也用于提供旨在驱动机动车的转矩。混合动力驱动设备在此具有多个驱动机组，尤其是多个不同类型的驱动机组。前述驱动机组在此例如形成所述驱动机组中的第一个。驱动机组尤其优选设计为内燃机。所述驱动机组中的另一个以电机形式存在。
混合动力驱动设备设计用于，至少暂时地提供由多个驱动机组提供的转矩供使用。因此，例如驱动力矩可以仅借助于驱动机组或者仅借助于电机产生。然而驱动机组以及电机也可以至少暂时地彼此有效连接，以便共同提供驱动转矩。
混合动力驱动设备具有一从动轴，该从动轴——优选刚性地和/或永久地——与机动车的车轮有效连接。变速器与从动轴——优选同样刚性地和/或永久地——有效连接。然而备选地，在变速器和从动轴之间可以设置离合器，尤其是起动离合器。备选地，离合器或起动离合器处于变速器和电机之间的有效连接中。另一个离合器，尤其是分离离合器可以布置在驱动机组和电机之间。驱动机组能借助于该离合器与电机耦合。备选地可以设计为，驱动机组与电机永久地有效连接。
因此在机动车的行驶运行期间，尤其是借助于驱动机组，使驱动机组和电机都通过变速器与混合动力驱动设备的从动轴有效连接。相应地，可以借助于驱动机组提供驱动转矩的至少一部分。电机同样可以额外地产生一部分驱动转矩。备选地，电机能以发电机方式运行或者由驱动机组牵引。
发明内容
因此，本发明的任务在于，提供一种用于运行机动车的混合动力驱动设备的方法，所述方法相对于已知的方法具有优点，尤其是提供了一种更好的电机温度管理。
根据本发明，借助于根据本发明所述的方法完成该任务。在本发明的一个设计方案中规定，在电机的温度超过第一温度限值时，借助于变速器减小电机和从动轴之间的传动比。当然，在电机运行产生驱动转矩的一部分时，出现了使电机温度升高的热量。然而，当电机由驱动机组牵引并进而近似无转矩地运行时，同样出现热量。
在此，混合动力驱动设备提供了仅由驱动机组产生的转矩。此外，电机由于其与从动轴或与驱动机组的耦合被一起牵引。在这种运行状态中由于涡流同样出现了热量，该热量也增大或会增大电机的温度。例如如果在较长的时间上驱动转矩仅借助于驱动机组在高转速的情况下产生，则电机的温度会显著升高。
此时如果该温度超过了第一温度限值，则应该尽可能阻止温度的进一步升高或者减小至电机中的热量引入。为此，使用了变速器，以便减小电机和从动轴之间的传动比。这表示，在从动轴的转速不变的情况下减小电机的转速，从而相应地也减小涡流和由该涡流产生的热量。尤其优选如此选择传动比，即机动车的行驶运行可以在不受损害的情况下继续。尤其如此选择减小的传动比，使得尽管被减小，然而由混合动力驱动设备或驱动机组提供的驱动转矩仍相当于额定转矩，该额定转矩例如由机动车的驾驶员和/或驾驶员辅助设备要求。
在本发明的另一个设计方案中规定，变速器具有变速器控制器，当电机的温度超过温度限值时在该变速器控制器处设定较小的最大转速。在变速器控制器处设定的最大转速在此取决于温度。因此，当电机温度比第一温度限值小或相当于该第一温度限值时，在变速器控制器处设定第一最大转速。然而，如果温度超过第一温度限值，则在变速器控制器处设定第二最大转速，该第二最大转速小于第一最大转速。当然也可以规定，根据电机的温度——尤其借助于数学关系式、综合特性曲线和/或表格——获取在变速器控制器处设定的最大转速。
如此设计变速器控制器，即该变速器控制器把电机或驱动机组的转速朝较高转速的方向限制到最大转速。即如果电机的实际转速超过最大转速，则变速器控制器如此操控变速器，即减小电机和从动轴之间的传动比，从而实现如上所述的效果。
在本发明的备选实施方案中可以规定，变速器控制器把温度与第一温度限值比较并且在超过第一温度限值时，操控变速器以减小传动比。变速器控制器此时不再具有最大转速作为输入参量。相反，变速器控制器本身获取电机的温度并把其与第一温度限值比较。第一温度限值可以被提供给变速器控制器作为输入参量供使用，或者固定地存储在变速器控制器中。如果变速器控制器确定，该温度超过第一温度限值，则变速器控制器通过已知的方式操控变速器以减小传动比。
本发明的另一个设计方案规定，能够在混合动力驱动设备的正常运行方式中在发动机运行方式、发电机运行方式和空转运行方式中运行电机；在温度超过第二温度限值时切换至安全运行方式中，在该安全运行方式中仅允许电机在空转运行方式中运行。即如果电机的温度相当于第二温度限值或者小于该第二温度限值，则存在混合动力驱动设备的正常运行方式。当然一旦电机的温度低于或相当于第二温度限值，也可以从安全运行方式再次切换至正常运行方式中。
在正常运行方式中，也可以在多个不同的运行方式中运行电机。因此，电机例如可以在发动机运行方式中用于提供至少一部分驱动转矩。相反，其可以在发电机运行方式中作为发电机用于把动能转化为电能。在空转运行方式中，电机不具有转矩以及由从动轴和/或驱动机组牵引。然而如果电机的温度超过了第二温度限值，则从正常运行方式切换至安全运行方式中。在该安全运行方式中，电机仅允许在空转运行方式中运行。尽管在安全运行方式中由于前述的涡流同样产生热量，然而明显比在发动机运行方式和/或发电机运行方式中小得多。
本发明的另一个设计方案规定，第二温度限值相当于或小于第一温度限值。如前所述，可以通过不同的方式降低电机的温度或在电机中产生的热量。一方面可以借助于变速器减小传动比，以便在从动轴的转速保持不变时减小电机的转速。此外可以从正常运行方式切换至安全运行方式中。
当然第二温度限值可以相当于第一温度限值，从而从正常运行方式切换至安全运行方式中的同时，减小电机和从动轴之间的传动比，然而优选规定，实现阶梯状的安全构想。为此，第二温度限值小于第一温度限值。即规定了，首先仅允许电机在空转运行方式中运行以及随后如果这种做法不充分，才减小电机和从动轴之间的传动比。
在本发明的另一个优选的设计方案中规定，使用定子温度、转子温度和/或冷却剂温度作为电机的温度。基本上可以任意选择和确定温度。然而优选其反映了电机的实际状态，尤其是在没有时间延迟或至少实时的情况下。例如，考虑把定子温度或转子温度作为温度，其中，该温度尤其直接在电机处测量。附加地或备选地，可以考虑冷却剂温度。当然也可以使用一包括多个温度或由多个温度组成的温度值作为温度。例如，由定子温度、转子温度和/或冷却剂温度或它们的任意组合获取温度值。
在本发明的另一个设计方案中规定，由至少一个运行参量和/或环境参量获取在减小时设定的传动比。当然可以自由选择或固定存储传动比，然而有利地，传动比由运行参量或环境参量确定。例如为此可以考虑数学关系式、综合特性曲线和/或表格，其中，运行参量和/或环境参量作为输入参量存在，以及传动比作为输出参量存在。
例如，在本发明的另一个设计方案中可以规定，使用温度、第一温度限值和/或第一温度限值和温度之间的温度差作为运行参量。在此，电机的瞬时温度或第一温度限值直接引入到待设定/调整的传动比中。尤其是传动比选择得越小，则电机的温度越高或者第一温度限值和温度之间的温度差越大。
最后，在本发明的优选的设计方案中规定，使用环境温度作为环境参量。电机的温度决定性地取决于环境温度。如果环境温度低，则电机比在环境温度高时冷却程度更强。相应有利的是，传动比选择得越小，则环境温度越高。
本发明还涉及一种机动车的混合动力驱动设备，该混合动力驱动设备尤其用于执行根据本发明所述的方法，其中，混合动力驱动设备具有驱动机组以及电机，所述驱动机组和电机在机动车的行驶运行期间通过变速器与混合动力驱动设备的从动轴有效连接。在此规定，混合动力驱动设备设计用于，在电机的温度超过第一温度限值时，借助于变速器减小电机和从动轴之间的传动比。
已经指出了这种做法的优点或者混合动力驱动设备的这种设计方案的优点。无论是混合动力驱动设备还是所述方法都能够根据前述实施方案进一步改进，从而在此参见上述实施方案。
附图说明
下面根据附图中示出的实施例详细阐述本发明，同时不限制本发明。其中，
图1示意性示出驱动设备。
具体实施方式
图1示意性示出例如用于机动车的驱动设备1，该驱动设备在此处示出的实施方案中作为混合动力驱动设备存在。相应地，驱动设备1具有至少两个驱动机组，即第一驱动机组2以及第二驱动机组3。第一驱动机组2例如能够以内燃机形式存在，第二驱动机组3以电机形式存在。
两个驱动机组2和3可以通过轴4刚性地和/或永久地彼此有效连接。然而也可以为轴4配设一分离离合器，借助于该分离离合器能中断驱动机组2和3之间的有效连接。第二驱动机组3或电机借助于功率电子装置5操控，该功率电子装置例如本身借助于控制器操控。
驱动设备1是机动车的动力传动系6的组成部分。驱动设备除了驱动机组2和3外优选还包括起动离合器7以及变速器8。变速器8通过起动离合器7与驱动设备1有效连接或者至少能够有效连接。动力传动系6具有车桥9，在示出的实施例中两个车轮10配属于该车桥。车桥9或者车轮10优选通过车桥差速传动装置11与变速器8有效连接，尤其是刚性地和/或永久地有效连接。相应地，车桥9或者车轮10能借助于驱动设备1驱动。在此，变速器8的输出轴作为驱动设备1的从动轴12存在。通过从动轴12，使得在变速器8和车桥9、尤其是车桥差速传动装置11之间存在有效连接，尤其是刚性地和/或永久地存在有效连接。
在此规定，在机动车的行驶运行期间，两个驱动机组2和3通过变速器8与从动轴12有效连接。例如，驱动机组3仅在空转运行方式中运行，且其中，其由驱动机组2牵引。然而由于涡流，在驱动机组3中产生导致温度升高的热量。这尤其在驱动机组3的转速高时出现。如果此时电机3的温度超过了第一温度限值，则应该借助于变速器8减小驱动机组3和从动轴12之间的传动比，从而在从动轴12的转速保持不变时减小驱动机组3的转速。借助于这种做法可以减小在驱动机组3中出现的热量并进而降低驱动机组3的温度。
