und dort insbesondere anhand der
Es ist daher Aufgabe der Erfindung, ein Verfahren zum Betrieb einer kombinierten, hydraulischen Betriebs- und Feststellbremse der eingangs genannten Gattung dahingehend zu verbessern, dass eine Positionsermittlung des Kraftübertragungselement mit einfachen Mitteln präzise durchgeführt werden kann.It It is therefore an object of the invention to provide a method for operating a Combined, hydraulic service and parking brake of the aforementioned Genus to improve that a position determination of the power transmission element precise with simple means be performed can.
Diese Aufgabe wird verfahrensmäßig dadurch gelöst, dass die Positionsermittlung des Kraftübertragungselementes durch eine elektrische Widerstandsmessung realisiert wird.These Task is procedurally characterized solved, that the position determination of the force transmission element by an electrical resistance measurement is realized.
Eine besonders vorteilhafte Weiterbildung des erfindungsgemäßen Verfahrens sieht vor, dass die Positionsermittlung des Kraftübertragungselementes zur Bestimmung, ob die Feststellbremse im Sinne eines Feststellbremsvorganges aktiviert oder gelöst ist, ausgewertet wird.A particularly advantageous embodiment of the method according to the invention provides that the position determination of the power transmission element to determine whether the parking brake in the sense of a parking brake operation activated or resolved is, is evaluated.
Bei einer besonders vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens wird die elektrische Widerstandsmessung zwischen einem mit dem Kraftübertragungselement verbundenen Teil und dem Bremsgehäuse durchgeführt.at a particularly advantageous embodiment of the method according to the invention is the electrical resistance measurement between a with the power transmission element connected part and the brake housing performed.
Dabei ist vorgesehen, dass einem Aktivierungszustand der Feststellbremse ein hoher Widerstandswert zugeordnet wird, während einem gelösten Zustand ein niedriger Widerstandswert zugeordnet wird.there is provided that an activation state of the parking brake a high resistance value is assigned while in a released state a low resistance is assigned.
Bei einer weiteren, besonders vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens ist vorgesehen, dass ein zum Lösen der Feststellbremse notwendiger hydraulischer Druckaufbau beendet wird, wenn eine Positionsveränderung des Kraftübertragungselementes ermittelt wird.at a further, particularly advantageous embodiment of the method according to the invention provided that one to solve the parking brake necessary hydraulic pressure buildup ended is when a position change of the power transmission element is determined.
Die oben genannte Aufgabe wird außerdem erfindungsgemäß dadurch gelöst, dass Mittel vorgesehen sind, die die Position des Kraftübertragungselementes durch eine elektrische Widerstandsmessung ermitteln.The The above object is also according to the invention thereby solved, in that means are provided which determine the position of the force transmission element determine by an electrical resistance measurement.
Eine besonders vorteilhafte Ausführung des Erfindungsgegenstandes sieht vor, dass das Kraftübertragungselement einen elektrisch leitfähigen Kragen und einen mit dem Kragen fest verbundenen, elektrisch isolierten Stößel aufweist, wobei der Kragen in und außer Kontakt mit einem elektrisch leitfähigen Teil bringbar ist.A particularly advantageous embodiment of the subject invention provides that the force transmission element an electrically conductive Collar and one with the collar firmly connected, electrically insulated Has ram, with the collar in and out Contact with an electrically conductive part can be brought.
Außerdem sind ein mit dem Kraftübertragungselement verbundenes Teil und das Bremsgehäuse mit elektrischen Anschlüssen versehen.Besides, they are one with the power transmission element connected part and the brake housing provided with electrical connections.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels im Zusammenhang mit der beiliegenden Zeichnung näher erläutert, deren einzige Figur eine axiale Schnittdarstellung einer kombinierten, hydraulischen Betriebs- und Feststellbremse zeigt, an der erfindungsgemäße Verfahren durchgeführt werden kann.The Invention will be related to an embodiment in the context closer with the enclosed drawing explains whose single figure is an axial sectional view of a combined, hydraulic service and parking brake, in the inventive method carried out can be.
