Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines Hybridantriebsstrangs sowie einen entsprechenden Hybridantriebsstrang.The invention relates to a method for operating a hybrid powertrain and a corresponding hybrid powertrain.
Aus der
Der Erfindung liegt insbesondere die Aufgabe zugrunde, einen Kundenkomfort zu erhöhen. Sie wird durch ein erfindungsgemäßes Verfahren entsprechend dem Anspruch 1 und durch eine erfindungsgemäße Ausgestaltung entsprechend dem Anspruch 6 gelöst. Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.The invention is in particular the object of increasing customer comfort. It is achieved by an inventive method according to claim 1 and by an embodiment according to the invention according to claim 6. Further developments of the invention will become apparent from the dependent claims.
Die Erfindung geht aus von einem Verfahren zum Betrieb eines Hybridantriebsstrangs, in dem in einem Getriebe, an das ein Elektromotor angebunden ist, für einen Getriebegangwechsel ein geschalteter Vorwärtsgetriebegang ausgelegt wird, ein zu schaltender Getriebegang synchronisiert wird und der zu schaltende Getriebegang eingelegt wird.The invention is based on a method for operating a hybrid powertrain, in which in a transmission to which an electric motor is connected, a switched forward gear is designed for a gear change, a gear to be switched is synchronized and the gear to be shifted is engaged.
Es wird vorgeschlagen, dass eine Brennkraftmaschine gestartet wird, indem eine zwischen dem Elektromotor und der Brennkraftmaschine angeordnete Lastschaltkupplung zumindest zeitweise geschlossen wird, nachdem der geschaltete Getriebegang ausgelegt und bevor der zu schaltende Getriebegang eingelegt wurde. Dadurch kann eine Reaktionszeit, innerhalb der die Brennkraftmaschine während eines Getriebegangwechsels gestartet wird, verringert werden. Ein Kundenkomfort kann gesteigert werden, insbesondere ohne dass der Hybridantriebsstrang hierfür einen zusätzlichen Starter, wie beispielsweise einen klassischen Ritzelstarter, aufweisen muss. Unter einem „Getriebe” soll dabei insbesondere ein Zahnräderwechselgetriebe verstanden werden, welches zumindest einen Getrieberadsatz umfasst, der für eine Schaltung von Getriebegängen mit Unterbrechung einer Last vorgesehen ist. Grundsätzlich ist das Verfahren in gleicher Weise für Getriebe mit einem einzigen Getrieberadsatz wie auch für ein als Doppelkupplungsgetriebe ausgebildetes Getriebe geeignet. Darunter, dass der Elektromotor an das Getriebe angebunden ist, soll insbesondere verstanden werden, dass das Getriebe zumindest eine, bezogen auf eine von der Brennkraftmaschine ausgehende Antriebsleistung, nach der Lastschaltkupplung angeordnete Getriebewelle aufweist, an die der Elektromotor angebunden ist.It is proposed that an internal combustion engine is started by at least temporarily closing a power-shift clutch arranged between the electric motor and the internal combustion engine, after the shifted transmission gear has been designed and before the transmission gear to be shifted has been engaged. As a result, a reaction time within which the internal combustion engine is started during a gear change can be reduced. Customer comfort can be increased, in particular without the hybrid powertrain having to have an additional starter, such as a classic pinion starter, for this purpose. A "gearbox" is to be understood in particular as meaning a gear change transmission which comprises at least one gear wheel set which is provided for a shift of gear trains with the interruption of a load. In principle, the method is equally suitable for transmissions with a single gear set as well as for a trained as a double clutch transmission. Including that the electric motor is connected to the transmission, should be understood in particular that the transmission has at least one, based on a starting from the engine drive power, arranged after the power shift clutch transmission shaft to which the electric motor is connected.
Vorzugsweise wird die Brennkraftmaschine bei einer Leistungsanforderung durch einen Fahrer während des Getriebegangwechsels gestartet. insbesondere auf die Leistungsanforderung durch den Fahrer kann durch ein solches Verfahren besonders schnell reagiert werden. Unter „während” soll dabei verstanden werden, dass die Brennkraftmaschine nach einem Auslegen des geschalteten Getriebegangs und vor einem Einlegen des zu schaltenden Getriebegangs gestartet wird. Unter einem „Auslegen eines Getriebegangs” soll dabei ein Lösen einer form- und/oder kraftschlüssigen Verbindung zwischen dem Elektromotor und einem Achsantrieb des Kraftfahrzeugs verstanden werden. Unter einem „Einlegen eines Getriebegangs” soll dabei insbesondere ein Herstellen einer form- und/oder kraftschlüssigen Verbindung zwischen dem Elektromotor und/oder der Brennkraftmaschine und dem Achsantrieb des Kraftfahrzeugs verstanden werden.Preferably, the engine is started at a power request by a driver during the gear change. In particular, the performance requirement by the driver can be responded very quickly by such a method. By "while" is to be understood that the internal combustion engine is started after a layout of the switched gear and before engaging the gear to be switched. A "disengagement of a transmission gear" should be understood to mean a release of a positive and / or non-positive connection between the electric motor and an axle drive of the motor vehicle. A "engagement of a transmission gear" should be understood to mean in particular a production of a positive and / or non-positive connection between the electric motor and / or the internal combustion engine and the final drive of the motor vehicle.
Bevorzugt wird in einem parallel angeordneten Teilgetriebe ein Getriebegang eingelegt, während oder nachdem die Brennkraftmaschine gestartet wird. Dadurch kann die Brennkraftmaschine unmittelbar nach ihrem Start über das parallel angeordnete Teilgetriebe mit einem Achsantrieb verbunden werden, ohne dass zunächst der zu schaltende Getriebegang in einem an den Elektromotor anschließenden Teilgetriebe eingelegt werden muss. Unter einem „Teilgetriebe” soll in diesem Zusammenhang insbesondere ein Teilgetriebe eines Doppelkupplungsgetriebes verstanden werden, wobei der Elektromotor an eines der Teilgetriebe angebunden ist. Unter dem „parallel angeordneten Teilgetriebe” soll insbesondere das Teilgetriebe des Doppelkupplungsgetriebes verstanden werden, welches bezogen auf einen Kraftfluss von der Brennkraftmaschine zu dem Achsantrieb parallel zu dem Elektromotor angeordnet ist. Unter einer „Anbindung des Elektromotors an eines der Teilgetriebe” soll insbesondere verstanden werden, dass der Elektromotor zwischen der Lastschaltkupplung und dem Teilgetriebe angeordnet ist.Preferably, a transmission gear is engaged in a parallel partial transmission, during or after the internal combustion engine is started. As a result, the internal combustion engine can be connected to an axle drive immediately after its start via the sub-transmission arranged in parallel, without first having to engage the transmission gear to be shifted in a sub-transmission adjoining the electric motor. A "partial transmission" is to be understood in this context in particular a partial transmission of a dual clutch transmission, wherein the electric motor is connected to one of the partial transmissions. The "parallel partial transmission" is to be understood in particular the partial transmission of the dual clutch transmission, which is arranged parallel to the electric motor relative to a power flow from the internal combustion engine to the final drive. A "connection of the electric motor to one of the partial transmissions" should in particular be understood to mean that the electric motor is arranged between the power-shift clutch and the partial transmission.
Weiter wird vorgeschlagen, dass eine parallel zu der Lastschaltkupplung angeordnete zweite Lastschaltkupplung geschlossen wird, nachdem die Brennkraftmaschine gestartet wurde. Dadurch kann eine Wirkverbindung zwischen der Brennkraftmaschine und dem Achsantrieb besonders schnell hergestellt werden.It is also proposed that a second power-shift clutch arranged parallel to the power-shift clutch be closed after the internal combustion engine has been started. As a result, an operative connection between the internal combustion engine and the final drive can be produced particularly quickly.
Vorzugsweise erfolgt in dem Getriebegangwechsel ein Rückschaltvorgang oder ein Hochschaltvorgang in einem Teilgetriebe des Getriebes.Preferably, in the gear change a downshift or upshift in a partial transmission of the transmission.
