Bei einem Verfahren zum Betrieb eines Doppelkupplungsgetriebes in einem Kraftfahrzeug wird zur Erzeugung eines Bremsmoments das Kupplungsglied eines der beiden Getriebestränge des Doppelkupplungsgetriebes in eine schleifende Stellung versetzt, in der die Kupplungsteile in einer kraft- bzw. momentenübertragenden Position stehen, jedoch zueinander eine Relativbewegung ausüben.In a method for operating a dual-clutch transmission in a motor vehicle, the coupling member of one of the two gear trains of the dual-clutch transmission is set in a sliding position in which the clutch parts are in a force- or torque-transmitting position, but exert relative movement to each other to generate a braking torque.
Description
Die Erfindung bezieht sich auf ein Verfahren zum Betrieb eines Doppelkupplungsgetriebes in einem Kraftfahrzeug nach dem Oberbegriff des Anspruches 1.The The invention relates to a method of operating a dual-clutch transmission in a motor vehicle according to the preamble of claim 1.

Offenbarung der ErfindungDisclosure of the invention
Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, über ein Doppelkupplungsgetriebe eine zusätzliche Bremswirkung zu erzielen.From Based on this prior art, the invention has the object underlying, via a dual-clutch transmission an additional To achieve braking effect.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst. Die Unteransprüche geben zweckmäßige Weiterbildungen an.These Task is according to the invention with the features of claim 1 solved. The subclaims give appropriate training.
Bei dem erfindungsgemäßen Verfahren zum Betrieb eines Doppelkupplungsgetriebes in einem Kraftfahrzeug wird zumindest ein Kupplungsglied in einem der beiden Getriebestränge des Doppelkupplungsgetriebes zur Erzeugung einer Bremswirkung in eine schleifende Position versetzt, in der die bewegbaren Kupplungsteile dieses Kupplungsgliedes in einer kraft- bzw. momentenübertragenden Position stehen, jedoch zueinander eine Relativbewegung ausüben können. Es handelt sich bei der schleifenden Position der Kupplungsteile um einen zusätzlichen Kupplungszustand, in den die Kupplung versetzt werden kann und der zum eingekuppelten bzw. geschlossenen und ausgekuppelten bzw. geöffneten Kupplungszustand hinzutritt. Konstruktive Änderungen sind zur Realisierung des schleifenden Kupplungszustandes grundsätzlich nicht erforderlich, da lediglich die Kupplungsteile in einen angenäherten Zustand verbracht werden müssen, der zwischen geöffneter und geschlossener Kupplung liegt, wofür vorhandene Kupplungssteller eingesetzt werden können.at the inventive method for operating a Dual clutch transmission in a motor vehicle will at least one Coupling member in one of the two transmission lines of Dual-clutch transmission for generating a braking effect in one offset sliding position in which the movable coupling parts this coupling member in a force or torque transmitting Position, however, relative to each other perform a relative movement can. It is at the sliding position of the Coupling parts to an additional coupling state, in which the clutch can be moved and the engaged or closed and disengaged or opened coupling state should occur. Design changes are for realization the grinding coupling state basically not required because only the coupling parts in an approximated state have to be spent between open and closed clutch is what existing clutch plate can be used.
Die Relativbewegung zwischen den Kupplungsteilen verhindert ein Blockieren des Antriebsstranges insbesondere für den Fall, dass gemäß einer vorteilhaften Ausführung die Kupplung im zweiten Getriebeteilstrang geschlossen ist. Zugleich werden über die schleifende Position der Kupplungsteile Momente übertragen, die die Funktion eines im Antriebsstrang wirksamen Bremsmomentes haben, so dass unabhängig von einem im Kraftfahrzeug eingesetzten Radbremssystem ein Bremsmoment erzeugt werden kann, welches auf die Fahrzeugräder wirkt und diese abbremst. Das Doppelkupplungsgetriebe als Bremssystem stellt eine eigenständige Bremse dar, die unabhängig von sonstigen Bremssystemen im Fahrzeug arbeitet, so dass für die Realisierung der Bremswirkung über das Doppelkupplungsgetriebe grundsätzlich auch keine Koordination mit einem sonstigen Bremssystem erforderlich ist, welches einer vom Antriebsstrang unabhängigen Fahrzeugdomäne wie dem Chassis zugeordnet ist.The Relative movement between the coupling parts prevents blocking the drive train in particular in the event that according to a advantageous embodiment, the clutch in the second transmission sub-strand closed is. At the same time be on the sliding position the clutch parts transmit moments that the function have an effective braking force in the drive train, so that independently from a wheel brake system used in the motor vehicle a braking torque can be generated, which acts on the vehicle wheels and this slows down. The dual-clutch transmission as a braking system provides an independent brake that is independent works from other brake systems in the vehicle, allowing for the realization of the braking effect on the dual-clutch transmission in principle also no coordination with another brake system required which is a non-driveline vehicle domain as assigned to the chassis.
Ein weiterer Vorteil liegt in der Möglichkeit, auch jedes Stellglied abbremsen zu können, welches sich im Antriebsstrang befindet bzw. wirkungsmäßig mit dem Antriebsstrang verbunden ist. Für den Fall, dass das Doppelkupplungsgetriebe in einem Hybridfahrzeug eingesetzt wird, das als Antriebsquelle eine Kombination von Verbrennungsmotor und Elektromotor besitzt, die beispielsweise als Parallelhybrid ausgeführt sind, kann auch der als Antriebsquelle fungierende Elektromotor gebremst werden.One Another advantage is the possibility of each actuator to be able to brake, which is located in the drive train or operatively connected to the drive train is. In the event that the dual-clutch transmission in a hybrid vehicle is used, the combination as a drive source of internal combustion engine and electric motor owns, for example designed as a parallel hybrid, and the functioning as a drive source Be braked electric motor.
Grundsätzlich kann über das Doppelkupplungsgetriebe eine zweite, unabhängig von der Radbremse funktionierende Bremse etabliert werden, wodurch insgesamt im Fahrzeug ein redundantes Bremssystem erreicht wird. Beispielsweise wird das Doppelkupplungsgetriebe als Sekundärbremssystem eingesetzt, welches ergänzend bzw. redundant zum Primärbremssystem verwendet wird. In diesem Fall kann das Primärbremssystem als so genannte Fail-Silent-System ausgelegt werden, das ohne Rückfallfunktion ausgestattet ist und im Schadensfall außer Funktion tritt; die Bremswirkung wird in dieser Situation von dem als Sekundärbremssystem dienenden Doppelkupplungsgetriebe erzeugt, bei dem mindestens ein Kupplungsglied in die schleifende Position versetzt wird.In principle, a second brake, which functions independently of the wheel brake, can be established via the dual-clutch transmission, as a result of which a redundant brake system is achieved overall in the vehicle. For example, the dual-clutch transmission is used as a secondary brake system, which is used in addition to or redundant to the primary brake system. In this case, the primary brake system can be referred to as so-called Fail-Silent system are designed, which is equipped without fallback function and in case of damage out of service; the braking effect is generated in this situation by serving as a secondary brake system dual-clutch transmission, wherein at least one coupling member is placed in the sliding position.
Voraussetzung für die Bremsmomenterzeugung im Doppelkupplungsgetriebe ist die schleifende Stellung eines Kupplungsgliedes in einem ersten Getriebestrang sowie entweder ebenfalls eine schleifende Stellung oder eine geschlossene Stellung des Kupplungsgliedes im zweiten Getriebestrang. Das Kupplungsglied im zweiten Getriebestrang darf jedenfalls nicht in geöffneter Stellung stehen, da in diesem Fall keine Bremswirkung erzielt werden könnte.requirement for brake torque generation in the dual-clutch transmission is the sliding position of a coupling member in a first Gear train and either also a grinding position or a closed position of the coupling member in the second Gear train. The coupling member in the second gear train is allowed at least not in an open position, because in this If no braking effect could be achieved.
Grundsätzlich können die Kupplungsglieder in beiden Getriebesträngen des Doppelkupplungsgetriebes unabhängig voneinander in die schleifende Position verstellt werden. Damit ist es möglich, das Kupplungsglied im ersten Getriebestrang zu schließen und im zweiten Getriebestrang schleifen zu lassen oder in umgekehrter Ausführung das Kupplungsglied im ersten Getriebestrang schleifen zu lassen und im zweiten Getriebestrang zu schließen. Des Weiteren können beide Kupplungsglieder gleichzeitig in den schleifenden Zustand zur Erzeugung eines Bremsmoments versetzt werden.in principle can the coupling links in both gear strands of the dual-clutch transmission independently in the sliding position can be adjusted. This makes it possible to close the coupling member in the first gear train and grind in the second gear train or in reverse Execution of the coupling member in the first gear train grind and close in the second gear train. Furthermore, both coupling members can simultaneously in offset the grinding state to generate a braking torque become.
Im bremsenden Zustand sind immer unterschiedliche Gangkombinationen im ersten und im zweiten Getriebestrang eingelegt und aufgrund der geschlossenen bzw. der schleifenden Kupplung aktiv. Es kann zweckmäßig sein, während der Bremsmomenterzeugung nur bestimmte Gangkombinationen zuzulassen, um zu große Drehzahlunterschiede in den Getriebesträngen und mögliche Beschädigungen im Doppelkupplungsgetriebe zu vermeiden. Bevorzugt werden immer unmittelbar aufeinander folgende Gangkombinationen eingestellt, also beispielsweise die Gangkombination zweiter/dritter Gang oder dritter/vierter Gang. Extreme Kombinationen, beispielsweise eine Gangkombination mit der höchsten Gangstufe in einem Getriebestrang und der niedrigsten Gangstufe im anderen Getriebestrang oder eine Kombination mit dem Rückwärtsgang werden zweckmäßigerweise vermieden.in the braking condition are always different gear combinations inserted in the first and in the second gear train and due to the closed or the sliding coupling active. It may be appropriate be, during brake torque generation only certain gear combinations to allow for excessive speed differences in the gear trains and possible damage in the dual-clutch transmission to avoid. Preference is always given to one another directly following one another Gear combinations set, so for example the gear combination second / third gear or third / fourth gear. Extreme combinations, For example, a gear combination with the highest gear in one gear train and the lowest gear in the other Gear train or a combination with the reverse gear are expediently avoided.
Die Bremsmomenterzeugung über das Doppelkupplungsgetriebe kann gemäß einer weiteren vorteilhaften Ausführung auch als Parkbremse während des Fahrzeugstillstands eingesetzt werden. Des Weiteren ist eine mindestens teilweise Kompensation einer unerwünschten Drehmomenterhöhung im Antriebsstrang durchführbar, die beispielsweise aufgrund einer Fehlerreaktion des Fahrers hervorgerufen wurde und potenziell die Fahrsicherheit beeinträchtigt, insbesondere die Fahrstabilität. Die Entscheidung hierüber wird vorzugsweise selbsttätig im Regel- bzw. Steuergerät im Kraftfahrzeug gefällt, beispielsweise im Rahmen eines Fahrassistenzsystems wie ESP (elektronisches Stabilitätsprogramm).The Braking torque generation via the dual-clutch transmission can according to a further advantageous embodiment also used as a parking brake during vehicle standstill become. Furthermore, an at least partial compensation of a unwanted torque increase in the drive train feasible, for example, due to an error response the driver was caused and potentially driving safety impaired, especially the driving stability. The decision on this is preferably automatic in the control unit in the motor vehicle, For example, in the context of a driver assistance system such as ESP (electronic Stability Program).
Um die Bremsmomente ohne Beschädigung von Kupplungsteilen erzeugen zu können, kann es zweckmäßig sein, die entsprechenden Kupplungsteile eines Kupplungsgliedes, welche vorzugsweise als zusammenwirkende Kupplungsscheiben ausgeführt sind, zu verstärken. Ebenso können auch Gangräder im Doppelkupplungsgetriebe verstärkt werden.Around the braking torques without damaging coupling parts it can be useful to be able to produce be, the corresponding coupling parts of a coupling member, which are preferably designed as cooperating clutch discs, to reinforce. Likewise, also in the Double clutch transmissions are reinforced.
Über eine entsprechende Auslegung des Doppelkupplungsgetriebes können über den Antriebsstrang des Kraftfahrzeugs Verzögerungen bis etwa 0.3 g erreicht werden, was grundsätzlich für die Funktion als Sekundärbremssystem ausreicht.about a corresponding design of the dual clutch transmission can over the powertrain of the motor vehicle delays to about 0.3 g can be achieved, which is basically for the function sufficient as a secondary brake system.
