Abstract
Die Erfindung betrifft ein Verfahren zum Schutz eines Kupplungssystems eines Fahrzeuges, bei welchem eine aktuelle Temperatur der Kupplung (3) bestimmt wird, wobei bei Überschreitung eines Temperaturschwellwertes durch die aktuelle Temperatur auf eine Überlastung der Kupplung (3) geschlossen wird. Bei einem Verfahren, bei welchem zerstörte Reibbeläge schnellstmöglich abgetragen werden und die Kupplung wieder einen zuverlässigen Betrieb ermöglicht, wird bei Erkennung der Überlastung in einen Regenerationsmodus der Reibbeläge zum Abbau beschädigten Reibmaterials an den Reibbelägen gewechselt.The invention relates to a method for protecting a clutch system of a vehicle, in which a current temperature of the clutch (3) is determined, is closed when exceeding a temperature threshold by the current temperature to an overload of the clutch (3). In a method in which destroyed friction linings are removed as quickly as possible and the clutch again enables reliable operation, upon detection of the overload in a regeneration mode of the friction linings for dismantling damaged friction material on the friction linings is changed.
Description
Die Erfindung betrifft ein Verfahren zum Schutz eines Kupplungssystems eines Fahrzeuges, bei welchem eine aktuelle Temperatur der Kupplung bestimmt wird, wobei bei Überschreitung eines Temperaturschwellwertes durch die aktuelle Temperatur auf eine Überlastung der Kupplung geschlossen wird. The invention relates to a method for protecting a clutch system of a vehicle, in which a current temperature of the clutch is determined, is closed when exceeding a temperature threshold by the current temperature to an overload of the clutch.
Aus der
Die
Nachteilig ist dabei, dass der Zeitraum bis zum Abfahren des beschädigten Reibmaterials sehr lange dauert und die Kupplung sich zwischenzeitlich in einem Zustand befindet, bei welchem das Übertragungsverhalten der Kupplung gestört ist. The disadvantage here is that the time until the shutdown of the damaged friction material takes a long time and the clutch is in the meantime in a state in which the transmission behavior of the clutch is disturbed.
Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren zum Schutz eines Kupplungssystems anzugeben, bei welchem kritische Zustände der Kupplung zuverlässig unterbunden werden.The invention is therefore based on the object to provide a method for protecting a clutch system, wherein critical states of the clutch are reliably prevented.
Erfindungsgemäß ist die Aufgabe dadurch gelöst, dass bei Erkennung der Überlastung in einem Regenerationsmodus der Reibbeläge zum Abbau geschädigten Reibmaterials an den Reibbelägen gewechselt wird. In diesem Regenerationsmodus kann sofort der geschädigte Reibbelag abgetragen werden, so dass die Kupplung schnellstmöglich wieder in einen Zustand versetzt wird, bei welchem ein gewünschtes Übertragungsverhalten realisiert wird. Das Verfahren hat den Vorteil, dass ein Durchrutschen der Kupplung nach einer starken thermischen Schädigung aufgrund eines Reibwertverlustes bei einer daraufhin folgenden Benutzung der Kupplung verhindert wird. According to the invention the object is achieved in that is changed when detecting the overload in a regeneration mode of the friction linings for degradation damaged friction material on the friction linings. In this regeneration mode, the damaged friction lining can be removed immediately, so that the coupling is returned as quickly as possible to a state in which a desired transmission behavior is realized. The method has the advantage that a slippage of the clutch is prevented after a strong thermal damage due to a loss of friction in a subsequent use of the clutch.
Vorteilhafterweise werden in dem Regenerationsmodus gezielt vorgegebene Energieeinträge in die Kupplung eingetragen. Mittels dieser Energieeinträge wird sichergestellt, dass die verbrannten Materialschichten abgearbeitet werden und wieder unbeschädigtes Reibmaterial in Eingriff kommt.Advantageously, predetermined energy inputs are entered into the clutch in the regeneration mode. By means of these energy inputs it is ensured that the burnt material layers are processed and again undamaged friction material is engaged.
In einer Ausgestaltung werden die Energieeinträge durch Betätigung der Kupplung infolge von Zwischenschaltungen und/oder Leerschaltungen eingebracht. Diese Zwischen- und/oder Leerschaltungen werden durch eine Steuereinrichtung bei der Überschreitung des Grenzwertes der Temperatur automatisch eingeleitet und erfolgen unabhängig vom Fahrverhalten des Fahrers. In one embodiment, the energy inputs are introduced by actuating the clutch as a result of intermediate circuits and / or empty circuits. These intermediate and / or empty circuits are automatically initiated by a control device when the limit value of the temperature is exceeded and take place independently of the driving behavior of the driver.
In einer Weiterbildung erfolgt der Regenerationsmodus bei einer konstanten Fahrgeschwindigkeit. Dies hat den Vorteil, dass Zwischenschaltungen und Leerschaltungen initiiert werden können, ohne dass ein Gangwechsel, zu welchem die Benutzung der Kupplung benötigt wird, eingeleitet werden muss. Dadurch werden Betriebsstörungen im Fahrablauf des Fahrzeuges verhindert. In a further development, the regeneration mode takes place at a constant driving speed. This has the advantage that intermediate circuits and idle circuits can be initiated without having to initiate a gear change to which the use of the clutch is required. This prevents malfunctions in the vehicle's running process.
In einer Ausführungsform wird die aktuelle Temperatur der Kupplung mittels eines Temperatursensors gemessen. Da ein solcher Temperatursensor in automatisierten Kupplungssystemen an sich vorhanden ist, kann das von dem Temperatursensor abgegebene Signal genutzt werden, ohne dass zusätzliche Bauelemente zur Nutzung des Verfahrens benötigt werden.In one embodiment, the current temperature of the clutch is measured by means of a temperature sensor. Since such a temperature sensor is present in automated coupling systems per se, the signal emitted by the temperature sensor can be used without the need for additional components for using the method.
In einer Alternative wird die aktuelle Temperatur der Kupplung mittels eines Temperaturmodells berechnet. Die Berechnung der aktuellen Temperatur hat den Vorteil, dass auf einen Temperatursensor verzichtet werden kann, welcher die Kupplungstemperatur nur lokal vermittelt, während die errechnete Temperatur einen Mittelwert aus einer Vielzahl von Einflüssen in der Kupplungsumgebung wiedergibt.In an alternative, the current temperature of the clutch is calculated by means of a temperature model. The calculation of the current temperature has the advantage that it can be dispensed with a temperature sensor, which communicates the clutch temperature only locally, while the calculated temperature represents an average of a variety of influences in the clutch environment.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Eine davon soll anhand der in der Zeichnung wiedergegebenen Figuren näher erläutert werden. The invention allows numerous embodiments. One of them will be explained in more detail with reference to the figures reproduced in the drawing.
