Description
Die Erfindung betrifft ein Verfahren zum Betrieb einer Verbrennungskraftmaschine eines Fahrzeugs nach den Merkmalen des Oberbegriffs des Anspruchs 1 und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for operating an internal combustion engine of a vehicle according to the features of the preamble of claim 1 and to an apparatus for carrying out the method.

Die Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zum Betrieb einer Verbrennungskraftmaschine eines Fahrzeugs mit den Merkmalen des Anspruchs 1 und eine Vorrichtung zur Durchführung des Verfahrens mit den Merkmalen des Anspruchs 4.The object is achieved by a method for operating an internal combustion engine of a vehicle having the features of claim 1 and an apparatus for performing the method with the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
In einem erfindungsgemäßen Verfahren zum Betrieb einer Verbrennungskraftmaschine eines Fahrzeugs wird eine Betriebsart der Verbrennungskraftmaschine, insbesondere ein Brennverfahren, mit welchem die Verbrennungskraftmaschine betrieben wird, in Abhängigkeit von aktuell vorliegenden und zukünftig vorliegenden Betriebsbedingungen ausgewählt.In a method according to the invention for operating an internal combustion engine of a vehicle, an operating mode of the internal combustion engine, in particular a combustion method with which the internal combustion engine is operated, is selected as a function of present and future operating conditions.
Durch die erfindungsgemäße Lösung werden eine Verringerung eines Kraftstoffverbrauchs und eine Reduzierung von Schadstoffemissionen erreicht.The solution according to the invention achieves a reduction of fuel consumption and a reduction of pollutant emissions.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand einer Zeichnung näher erläutert.Embodiments of the invention will be explained in more detail below with reference to a drawing.
Dabei zeigt:Showing:
Die Vorrichtung
Eine solche Kombination verschiedener Betriebsarten, insbesondere Brennverfahren, d. h. die Auswahl einer für die jeweiligen aktuell vorliegenden und zukünftig vorliegenden Betriebsbedingungen am besten geeigneten Betriebsart aus einer Mehrzahl zur Verfügung stehender Betriebsarten, insbesondere eines jeweils am besten geeigneten Brennverfahrens aus einer Mehrzahl zur Verfügung stehender Brennverfahren, welche mit der jeweiligen Verbrennungskraftmaschine
Insbesondere bei einer als ein Ottomotor ausgebildeten Verbrennungskraftmaschine
Die Motorsteuerung, d. h. die Steuerungs- und/oder Regelungseinheit
Da sich Randbedingungen in Abhängigkeit von einer jeweiligen Fahrsituation schnell ändern können, würde sich, wenn nur die oben genannten Betriebsbedingungen berücksichtigt werden würden, jedoch häufig eine suboptimale Betriebsartenwahl ergeben oder es müsste häufig die Betriebsart gewechselt werden. Beispielsweise ist das Umschalten auf den Katalysatorheizbetrieb kurz vor einer Steigung oder kurz vor einer Autobahnstrecke nicht sinnvoll. Betriebsartenwechsel sind mit kurzzeitig erhöhtem Kraftstoffverbrauch und erhöhten Schadstoffemissionen verbunden. Zusätzlich verschlechtert sich eine Laufruhe der Verbrennungskraftmaschine
Daher wird die Betriebsartenwahl des Weiteren automatisiert, vorausschauend und fahrsituationsabhängig durchgeführt, um derartige Probleme zu vermeiden oder zumindest zu minimieren. Hierzu werden zusätzlich zu den oben genannten Betriebsbedingungen eine oder mehrere weitere Betriebsbedingungen berücksichtigt, insbesondere ein vorausliegendes Streckenprofil, beispielsweise ein Höhenprofil, Kurven und/oder Kreuzungen, und/oder ein oder mehrere Verkehrszeichen, zum Beispiel Warnzeichen, und/oder eine oder mehrere Geschwindigkeitsbegrenzungen und/oder ein Abstand zwischen dem Fahrzeug und einem vorausfahrenden Objekt. Beispielsweise wird eine Position des Fahrzeugs mittels eines globalen Navigationssatellitensystems festgestellt und das vorausliegende Streckenprofil ermittelt.Therefore, the mode selection is further automated, predictive, and driving-dependent, to avoid or at least minimize such problems. For this purpose, in addition to the above-mentioned operating conditions, one or more further operating conditions are taken into account, in particular a preceding route profile, for example a height profile, curves and / or intersections, and / or one or more traffic signs, for example warning signs, and / or one or more speed limits and / or a distance between the vehicle and a preceding object. By way of example, a position of the vehicle is determined by means of a global navigation satellite system and the preceding route profile is determined.
Zusätzlich werden beispielsweise ein Streckenziel aus einer Eingabe in ein Navigationssystem des Fahrzeugs, eine Fahrtroute aus dem Navigationssystem und/oder eine oder mehrere Informationen aus einem Radarsensorsystem des Fahrzeugs und/oder eine oder mehrere Informationen aus einer Bordkamera des Fahrzeugs berücksichtigt.In addition, for example, a route destination from an input to a navigation system of the vehicle, a route from the navigation system and / or one or more information from a radar sensor system of the vehicle and / or one or more information from an on-board camera of the vehicle are taken into account.
