Description
Die Erfindung betrifft ein Verfahren zum Betreiben eines Antriebsstrangs eines Kraftfahrzeugs nach dem Oberbegriff des Anspruchs 1.The The invention relates to a method for operating a drive train of a motor vehicle according to the preamble of claim 1.
Die Hauptkomponenten eines Antriebsstrangs 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, wobei ein Antriebsstrang neben dem Antriebsaggregat und dem Getriebe weiterhin über mindestens ein sogenanntes Nebenaggregat verfügt. Bei einem Nebenaggregat handelt es sich um eine Baugruppe des Antriebsstrangs, die zwar zum Betrieb des Antriebsstrangs erforderlich ist, die jedoch selbst am Abtrieb des Antriebsstrangs kein Antriebs-moment bereitstellt. Bei einem solchen Nebenaggregat kann es sich um eine Hydraulikpumpe, eine Wasserpumpe, einen Klimakompressor, einen Luftpresser oder um eine Lenkhilfspumpe handeln. Nebenaggregate können getriebeinterne oder eine getriebeexterne Baugruppen sein.The Main components of a powertrain are a drive unit and a gearbox. The transmission converts speeds and torques and thus provides a traction power supply of the drive unit to an output the powertrain ready. The present invention relates a method of operating a powertrain, wherein a powertrain next to the drive unit and the transmission continue to at least a so-called accessory has. For an accessory is an assembly of the powertrain, although to drive the powertrain is required, but the self at the output of the drive train no drive torque provides. Such an accessory may be a hydraulic pump, a water pump, an air conditioning compressor, an air compressor or to act a power steering pump. Auxiliary units can be internal or internal be gear-external assemblies.
Aus dem Stand der Technik ist es bereits bekannt, dass für Nebenaggregate mindestens zwei unterschiedliche Betriebsmodi zur Verfügung stehen, nämlich ein Standby-Betriebsmodus, in welchem das jeweilige Nebenaggregat energiesparend, jedoch ohne Gewährleistung einer Fahrbereitschaft betrieben wird, und ein Fahr-Betriebsmodus, in welchem das jeweilige Nebenaggregat unter Gewährleistung einer Fahrbereitschaft für einen ordnungsgemäßen Fahrbetrieb des Kraftfahrzeugs betrieben wird. Bei aus dem Stand der Technik bekannten Antriebssträngen ist es weiterhin bekannt, derartige Nebenaggregate dann im Standby-Betriebsmodus zu betreiben, wenn das Getriebe auf Neutral geschaltet wird bzw. wenn ein Fahrer an einem Fahrschalter die Neutralstellung fürs Getriebe wählt.Out the prior art, it is already known that for ancillaries at least two different operating modes are available, namely a Standby operating mode, in which the respective ancillary unit saves energy, but without warranty a driving standby is operated, and a driving mode of operation, in which the respective auxiliary unit under ensuring a driving readiness for one proper driving of the motor vehicle is operated. In from the prior art known drive trains it is also known, such ancillaries then in standby mode of operation operate when the transmission is switched to neutral or if a driver at a drive switch the neutral position for the transmission chooses.
Legt hingegen ein Fahrer am Fahrschalter eine Fahrstufe für eine Vorwärtsfahrt oder eine Rückwärtsfahrt ein, so werden bei aus dem Stand der Technik bekannten Antriebssträngen die Nebenaggregate vom Standby-Betriebsmodus in den Fahr-Betriebsmodus überführt und im Fahr-Betriebsmodus betrieben.sets however, a driver at the drive switch a gear for a forward drive or a reverse drive a, so in known from the prior art drive trains the Ancillaries from standby mode of operation transferred to the driving mode of operation and operated in driving mode.
Hiervon ausgehend liegt der vorliegenden Erfindung das Problem zu Grunde, ein neuartiges Verfahren zum Betreiben eines Antriebsstrangs eines Kraftfahrzeugs zu schaffen. Dieses Problem wird durch ein Verfahren zum Betreiben eines Antriebsstrangs eines Kraftfahrzeugs gemäß Anspruch 1 gelöst. Erfindungsgemäß wird ein aktueller Betriebsmodus für das oder jedes Nebenaggregat abhängig vom Zustand mindestens einer Tür des Kraftfahrzeugs bestimmt.Of these, Based on the present invention, the problem underlying a novel method for operating a drive train of a To create motor vehicle. This problem is solved by a procedure for operating a drive train of a motor vehicle according to claim 1 solved. According to the invention is a current operating mode for depending on the or each accessory from the condition of at least one door of the motor vehicle.
Mit der hier vorliegenden Erfindung wird erstmals vorgeschlagen, einen Betriebsmodus für ein Nebenaggregat eines Antriebsstrangs abhängig vom Zustand mindestens einer Tür des Kraftfahrzeugs zu bestimmen. Dann, wenn mindestens eine Tür des Kraftfahrzeugs geöffnet ist, wird das oder jedes Nebenaggregat im Standby-Betriebsmodus betrieben. Dann hingegen, wenn die Türen des Kraftfahrzeugs geschlossen sind, wird das oder jedes Nebenaggregat im Fahr-Betriebsmodus betrieben. Mit der hier vorliegenden Erfindung ist es möglich, einen Antriebsstrang eines Kraftfahrzeugs noch energiesparender zu betreiben. Weiterhin können Geräuschemissionen der Nebenaggregate verringert werden.With the present invention is proposed for the first time, a Operating mode for an accessory of a powertrain depending on the state at least a door of the motor vehicle. Then, if at least one door of the motor vehicle open is, the or each accessory is in standby mode of operation operated. Then, on the other hand, when the doors of the motor vehicle are closed are, the or each accessory is operated in the driving mode of operation. With the present invention, it is possible to use a powertrain to operate a motor vehicle even more energy efficient. Farther can noise emissions ancillary units are reduced.
Da bereits mit Schließen der Türen eines Kraftfahrzeugs die Fahrbereitschaft der Nebenaggregate hergestellt wird, kann früher mit einem Anfahren begonnen werden, als dann, wenn die Fahrbereitschaft erst mit Wahl einer Fahrstufe für eine Vorwärtsfahrt oder eine Rückwärtsfahrt am Wählhebel des Fahrzeugs hergestellt würde.There already with closing the doors a motor vehicle prepared the driving readiness of the ancillaries can, can sooner to start with a start, then when the driving readiness only with the choice of a gear for a forward drive or a reverse drive on the selector lever of the Vehicle would be manufactured.
