Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines zumindest ein Doppelkupplungsgetriebe und einen Hybridantrieb umfassenden Antriebsstrangs eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for operating a drive train of a motor vehicle comprising at least one double clutch transmission and a hybrid drive.
Die Hauptkomponenten eines Antriebsstrangs eines Kraftfahrzeugs sind ein Antriebsaggregat und ein Getriebe. Ein Getriebe wandelt Drehmomente und Drehzahlen und setzt so das Zugkraftangebot des Antriebsaggregats um. Die hier vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines Antriebsstrangs, der zumindest ein als Doppelkupplungsgetriebe ausgebildetes Getriebe und als Antriebsaggregat einen Hybridantrieb umfasst.The main components of a drive train of a motor vehicle are a drive unit and a transmission. A gearbox converts torques and speeds and thus implements the traction power offered by the drive unit. The present invention relates to a method for operating a drive train which comprises at least one transmission designed as a double clutch transmission and a hybrid drive as the drive unit.

Ferner geht aus der
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, ein neuartiges Verfahren zum Betreiben eines ein Doppelkupplungsgetriebe und einen Hybridantrieb umfassenden Antriebsstrangs zu schaffen und den Wirkungsgrad weiter zu verbessern.Proceeding from this, the present invention is based on the problem of creating a novel method for operating a drive train comprising a double clutch transmission and a hybrid drive and further improving the efficiency.
Dieses Problem wird durch ein Verfahren zum Betreiben eines ein Doppelkupplungsgetriebe und einen Hybridantrieb umfassenden Antriebsstrangs gemäß Anspruch 1 gelöst.This problem is solved by a method for operating a drive train comprising a dual clutch transmission and a hybrid drive according to
Erfindungsgemäß wird dann, wenn im Generatorbetrieb des Elektromotors insbesondere zum Betreiben elektrischer Verbraucher von demselben eine Generatorleistung angefordert wird, die deutlich geringer ist als die vom Elektromotor bereitstellbare Generatorleistung, der Elektromotor nach vorgegebenen zeitlichen Intervallen wechselnd vom Abtrieb abgekoppelt und an den Abtrieb angekoppelt, wobei beim Abkoppeln des Elektromotors vom Abtrieb das erste Teilgetriebe in die Neutralposition überführt und die dem ersten Teilgetriebe zugeordnete erste Kupplung geöffnet wird.According to the invention, when in generator operation of the electric motor, in particular for operating electrical consumers, a generator power is requested from the electric motor that is significantly lower than the generator power that can be provided by the electric motor, the electric motor is alternately decoupled from the output and coupled to the output according to predetermined time intervals, whereby at Uncoupling the electric motor from the output, the first partial transmission is transferred to the neutral position and the first clutch associated with the first partial transmission is opened.
Mit der hier vorliegendenden Erfindung wird vorgeschlagen, dass dann, wenn im Generatorbetrieb des Elektromotors derselbe nur eine relativ geringe Generatorleistung bereitstellen muss, der Elektromotor nach vorgegebenen zeitlichen Intervallen vom Abtrieb abgekoppelt wird. Dann, wenn der Elektromotor vom Abtrieb abgekoppelt ist, können elektrische Verluste des Elektromotors im Generatorbetrieb vermieden werden.The present invention proposes that when the generator only has to provide a relatively low generator power when the electric motor is operating, the electric motor is decoupled from the output at predetermined time intervals. When the electric motor is decoupled from the output, electrical losses of the electric motor in generator operation can be avoided.
Nach einer vorteilhaften Weiterbildung der Erfindung wird dann, wenn der Verbrennungsmotor über das zweite Teilgetriebe und die dem zweiten Teilgetriebe zugeordnete Kupplung in den Antriebsstrang eintreibt, das nach vorgegebenen zeitlichen Intervallen wechselnde Abkoppeln des Elektromotors vom Abtrieb ohne Änderung der Anbindung des Verbrennungsmotors an den Abtrieb durchgeführt wird. Dann hingegen, wenn der Verbrennungsmotor über das erste Teilgetriebe und die dem ersten Teilgetriebe zugeordnete Kupplung in den Antriebsstrang eintreibt, wird das nach vorgegebenen zeitlichen Intervallen wechselnde Abkoppeln des Elektromotors vom Abtrieb mit vorheriger Änderung der Anbindung des Verbrennungsmotors an den Abtrieb durchgeführt, wobei hierzu eine Lastumschaltung des Verbrennungsmotors vom ersten Teilgetriebe auf das zweite Teilgetriebe erfolgt. According to an advantageous development of the invention, when the internal combustion engine drives into the drive train via the second partial transmission and the clutch assigned to the second partial transmission, the uncoupling of the electric motor from the output, which changes according to predetermined time intervals, is carried out without changing the connection of the internal combustion engine to the output . Then, on the other hand, when the internal combustion engine drives into the drive train via the first partial transmission and the clutch assigned to the first partial transmission, the uncoupling of the electric motor from the output, which changes according to predetermined time intervals, is carried out with a previous change in the connection of the internal combustion engine to the output, with a load switchover for this purpose of the internal combustion engine from the first sub-transmission to the second sub-transmission.
