Besonders vorteilhaft ist, dass das mindestens eine erste Fluidbauelement als Teil des Fluidaggregats des Bremssystems ausgeführt ist. Dadurch können die zusätzlichen Elemente bzw. Bauteile der Kupplungsvorrichtung mit minimalem Aufwand in das bestehende Bremssystem integriert werden. Zudem können die Kupplungsvorrichtung und das Bremssystem in vorteilhafter Weise einen gemeinsamen Fluidvorratsbehälter und getrennte Fluidkreisläufe aufweisen. Das mindestens eine erste Fluidbauelement und/oder das mindestens eine zweite Fluidbauelement können beispielsweise als Magnetventil und/oder als Rückschlagventil und/oder als Pumpenelement ausgeführt werden. Die Pumpenelemente können beispielsweise als Kolbenpumpe und/oder als Zahnradpumpe ausgeführt und mit einem gemeinsamen Antrieb gekoppelt werden.Especially It is advantageous that the at least one first fluid component is designed as part of the fluid assembly of the brake system. Thereby can the additional Elements or components of the coupling device with minimal effort be integrated into the existing braking system. In addition, the Coupling device and the brake system in an advantageous manner have a common fluid reservoir and separate fluid circuits. The at least one first fluid component and / or the at least a second fluid component can For example, as a solenoid valve and / or as a check valve and / or as a pump element accomplished become. The pump elements can For example, designed as a piston pump and / or as a gear pump and be coupled with a common drive.

Diese Daten umfassen beispielsweise Informationen über den aktuellen Fahrzeugzustand, über aktuelle Fahrdynamikgrößen usw. Während eines Antiblockierregelvorgangs kann die Auswerte- und Steuereinheit das Kupplungsaggregat über das mindestens eine erste Fluidbauelement in vorteilhafter Weise aktivieren, um einen Antriebsstrang des Fahrzeugs zu trennen. Dadurch können die Räder in vorteilhafter Weise auch dann dynamisch gebremst werden, wenn der Fahrer bei einer Panikbremsung das Kupplungspedal nicht betätigt. Während eines Anfahrvorgangs kann die Auswerte- und Steuereinheit das Kupplungsaggregat über das mindestens eine erste Fluidbauelement in vorteilhafter Weise aktivieren, um ein Abwürgen des Motors zu verhindern.In a further refinement of the clutch arrangement according to the invention, the evaluation and control unit controls the at least one first fluid component and / or the at least one second fluid component as a function of data which is provided by at least one sensor. During an anti-skid control operation, the evaluation and control unit can advantageously activate the clutch unit via the at least one first fluid component in order to separate a drive train of the vehicle. As a result, the wheels can also be braked dynamically in an advantageous manner even when the driver does not actuate the clutch pedal during panic braking. During a starting process, the evaluation and control unit, the clutch unit via the activate at least a first fluid component in an advantageous manner to prevent stalling of the engine.
In weiterer Ausgestaltung der erfindungsgemäßen Kupplungsanordnung ist das Kupplungspedal vom Fluidkreislauf der Kupplungsvorrichtung getrennt, wobei eine Betätigung des Kupplungspedals von einer Sensoreinheit detektierbar und von der Auswerte- und Steuereinheit zur Ansteuerung des mindestens einen ersten Fluidbauelements auswertbar ist.In Another embodiment of the coupling arrangement according to the invention the clutch pedal is disconnected from the fluid circuit of the clutch device, being an actuation of the clutch pedal detectable by a sensor unit and by the evaluation and Control unit for controlling the at least one first fluid component is evaluable.
In Abhängigkeit von der Ausführung der Kupplungsvorrichtung sind verschiedene Varianten zur Ausführung eines Kupplungsvorgangs möglich. So kann beispielsweise bei einer kostengünstigen Ausführung mit einem Magnetventil als erstes Fluidbauelement eine rein passive Unterstützung des Kupplungsvorgangs bereitgestellt werden. Durch diese Ausführungsform kann in vorteilhafter Weise ein Abwürgen des Fahrzeugmotors verhindert werden. Wird zusätzlich ein Pumpenelement als ersts Fluidbauelement bereitgestellt, dann kann der Kupplungsvorgang aktiv unterstützt werden, so dass auch ein selbstständiger Eingriff ohne Betätigung des Kupplungspedals möglich ist. Durch die Trennung des Kupplungspedals vom Fluidkreislauf der Kupplungsvorrichtung und die Verwendung der Sensoreinheit ist eine rein elektronische Kupplungsbetätigung möglich.In dependence from the execution the coupling device are different variants for the execution of a Coupling process possible.
