Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Antriebsstrangs eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for operating a drive train of a motor vehicle according to the preamble of
Die Hauptkomponenten eines Antriebsstrangs eines Kraftfahrzeugs sind ein Antriebsaggregat und ein Getriebe. Das Getriebe wandelt Drehzahlen und Drehmomente und stellt so ein Zugkraftangebot des Antriebsaggregats an einem Abtrieb des Antriebsstrangs bereit. Die hier vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines Antriebsstrangs eines Hybridfahrzeugs, dessen Antriebsaggregat zumindest eine elektrische Maschine und einen Verbrennungsmotor umfasst. Die elektrische Maschine ist zwischen den Verbrennungsmotor und ein automatisiertes Schaltgetriebe geschaltet. Das automatisierte Schaltgetriebe ist zwischen die elektrische Maschine und den Abtrieb geschaltet ist. Zwischen die elektrische Maschine und das automatisierten Schaltgetriebe ist eine Reibkupplung geschaltet.The main components of a drive train of a motor vehicle are a drive unit and a transmission. The transmission converts speeds and torques and thus provides a traction power supply of the drive unit at a power take-off of the drive train ready. The present invention relates to a method for operating a drive train of a hybrid vehicle, the drive unit of which comprises at least one electric machine and one internal combustion engine. The electric machine is connected between the combustion engine and an automated manual transmission. The automated manual transmission is connected between the electric machine and the output. Between the electric machine and the automated transmission, a friction clutch is connected.
Im automatisierten Schaltgetriebe werden Schaltungen unter Unterbrechung des vom Antriebsaggregat an dem Abtrieb bereitgestellten Antriebsmoments ausgeführt. Solche Schaltungen mit Unterbrechung des Antriebsmoments werden so ausgeführt, dass zunächst in einer ersten Phase das vom Antriebsaggregat an dem Abtrieb bereitgestellte Antriebsmoment abgebaut, anschließend in einer zweiten Phase die eigentliche Schaltung bzw. ein Gangwechsel im Schaltgetriebe von einem Ist-Gang in einen Ziel-Gang ausgeführt und darauffolgend in einer dritten Phase am Abtrieb Antriebsmoment wieder aufgebaut wird. Die eigentliche Schaltung bzw. der eigentliche Gangwechsel im automatisierten Schaltgetriebe erfolgt derart, dass zunächst der Ist-Gang der auszuführenden Schaltung ausgelegt wird, anschließend eine Getriebeeingangswelle des automatisierten Schaltgetriebes synchronisiert und darauffolgend der Ziel-Gang der auszuführenden Schaltung eingelegt wird.In the automated manual transmission circuits are performed interrupting the drive provided by the drive unit at the output drive torque. Such circuits with interruption of the drive torque are carried out so that first degraded in a first phase provided by the drive unit at the output drive torque, then in a second phase, the actual circuit or a gear change in the transmission from an actual gear in a target gear executed and subsequently in a third phase at the output drive torque is rebuilt. The actual circuit or the actual gear change in the automated manual transmission is such that initially the actual gear of the circuit to be executed is designed, then synchronized a transmission input shaft of the automated transmission and subsequently the target gear of the circuit to be executed is inserted.
In der Praxis erfolgt die Synchronisierung der Getriebeeingangswelle dann, wenn die zwischen die elektrische Maschine und das automatisierte Schaltgetriebe geschaltete Reibkupplung geöffnet ist. Zur Synchronisierung der Getriebeeingangswelle dienen nach der Praxis sogenannte Synchronringe. Dabei können sich relativ lange Schaltzeiten ergeben.In practice, the synchronization of the transmission input shaft takes place when the switched between the electric machine and the automated transmission friction clutch is open. To synchronize the transmission input shaft are used in practice so-called synchronizer rings. This can result in relatively long switching times.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, ein neuartiges Verfahren zum Betreiben eines Antriebsstrangs zu schaffen. Dieses Problem wird durch ein Verfahren gemäß Anspruch 1 gelöst. Erfindungsgemäß wird zum Ausführen der eigentliche Schaltung nach einem Gangauslegen eines Ist-Gangs der Schaltung und vor einem Gangeinlegen eines Ziel-Gangs der Schaltung eine Getriebeeingangswelle des automatisierten Schaltgetriebes unter Ausnutzen einer Schwungmasse der elektrischen Maschine synchronisiert.On this basis, the present invention based on the problem to provide a novel method for operating a drive train. This problem is solved by a method according to
Beim erfindungsgemäßen Verfahren erfolgt die Synchronisierung der Getriebeeingangswelle des automatisierten Schaltgetriebes nach dem Gangauslegen des Ist-Gangs und vor dem Gangeinlegen des Ziel-Gangs unter Ausnutzung der Schwungmasse der elektrischen Maschine. Hierzu wird die elektrische Maschine dann, wenn die zwischen die elektrische Maschine und das automatisierte Schaltgetriebe geschaltete Reibkupplung geöffnet ist, auf eine Schwungdrehzahl gebracht, wobei anschließend die Reibkupplung möglichst schnell geschlossen wird.In the method according to the invention, the synchronization of the transmission input shaft of the automated transmission after the gear layout of the actual gear and before the gear engagement of the target gear taking advantage of the flywheel of the electric machine. For this purpose, when the friction clutch connected between the electric machine and the automated manual transmission is opened, the electric machine is brought to a rotational speed, with the friction clutch then being closed as quickly as possible.
Eine sich hierbei aufgrund der Massenträgheit der elektrischen Maschine sowie aufgrund einer getriebeeingangsseitigen Massenträgheit einstellende Drehzahl entspricht der Synchrondrehzahl des Ziel-Gangs der auszuführenden Schaltung. Auf Synchronringe kann verzichtet werden. Weiterhin kann eine zur Ausführung einer Schaltung benötigte Zeit verkürzt werden.A speed which in this case is established on the basis of the mass inertia of the electric machine and on the basis of a transmission input inertia corresponds to the synchronous speed of the target gear of the circuit to be executed. On synchronizer rings can be dispensed with. Furthermore, a time required to execute a circuit can be shortened.

Dann, wenn in diesem Zusammenhang die Synchrondrehzahl des Ziel-Gangs überschritten wurde, wird sowohl bei einer Hochschaltung als auch bei einer Rückschaltung ein negativer Offset-Wert zur Korrektur der Schwungdrehzahl verwendet.Then, in this connection, when the synchronous speed of the target gear has been exceeded, a negative offset value is used for both the upshifting and the downshifting to correct the rotating speed.
Dann, wenn in diesem Zusammenhang die Synchrondrehzahl unterschritten wurde, wird sowohl zur Ausführung einer Hochschaltung als auch zur Ausführung einer Rückschaltung ein positiver Offset-Wert zur Korrektur der Schwungdrehzahl verwendet.Then, when the synchronous speed has been undershot in this connection, a positive offset value is used both for performing an upshift and for performing a downshift to correct the flywheel speed.
