Description
Die Erfindung betrifft ein Verfahren zur Betriebsartschaltung eines Hybridfahrzeugs, ein Computerprogrammprodukt, ein Steuergerät und ein Hybridfahrzeug.The invention relates to a method for the mode switching of a hybrid vehicle, a computer program product, a control device and a hybrid vehicle.
Die
Das erfindungsgemäße Verfahren zur Betriebsartschaltung eines Hybridfahrzeugs, wobei das Hybridfahrzeug einen Verbrennungsmotor, einen Elektromotor, einen Partikelfilter für den Verbrennungsmotor und ein Steuergerät zur Schaltung der Betriebsart zwischen einem aktiven Verbrennungsmotor und einem aktiven Elektromotor umfasst, umfassend die Schritte:
- a) Ermitteln eines Beladungszustandes des Partikelfilters;
- b) Vergleichen des Beladungszustandes mit einem Sollzustand für die Beladung;
- c) Schalten und/oder Beibehaltung der Betriebsart eines aktiven Verbrennungsmotors, wenn der ermittelte Beladungszustand von dem Sollzustand abweicht.
- a) determining a loading condition of the particulate filter;
- b) comparing the loading state with a desired state for the loading;
- c) switching and / or maintaining the operating mode of an active internal combustion engine when the determined load state deviates from the desired state.
Die Beladung des Partikelfilters entspricht einer Menge an Aschepartikeln und/oder Rußpartikeln, welche sich innerhalb des Partikelfilters befindet. Im Folgenden werden Aschepartikel und/oder Rußpartikel als Asche bezeichnet. Demzufolge werden Beladungen des Partikelfilters mit Asche als Aschebeladungen bezeichnet.The loading of the particulate filter corresponds to an amount of ash particles and / or soot particles which is located inside the particulate filter. In the following, ash particles and / or soot particles are referred to as ash. As a result, loads of the particulate filter with ash are referred to as ash charges.
Im Zuge der Erfindung hat sich gezeigt, dass Partikelfilter für Aschebeladungen unterhalb von einigen Gramm eine verminderte Filtereffizienz aufweisen. Es zeigte sich weiter, dass sich bei einer Betriebsart eines aktiven Elektromotors die Aschebeladung im Partikelfilter nur geringfügig und/oder gar nicht erhöht. Dahingegen erhöht sich die Aschebeladung schneller bei einer Betriebsart mit aktivem Verbrennungsmotor.In the course of the invention it has been shown that particle filters for ash charges below a few grams have a reduced filter efficiency. It was further shown that in an operating mode of an active electric motor, the ash charge in the particulate filter increases only slightly and / or not at all. On the other hand, the ash charge increases faster in an operating mode with an active combustion engine.
Eine Betriebsartschaltung auf einen aktiven Verbrennungsmotor ermöglicht eine schnelle Erhöhung der Filtereffizienz.Mode switching to an active engine allows a fast increase in filter efficiency.
Ein erfindungsgemäßes Computerprogrammprodukt umfasst ein Programm das, wenn es von einem Steuergerät ausgeführt wird, das Steuergerät veranlasst, ein erfindungsgemäßes Verfahren durchzuführen.A computer program product according to the invention comprises a program which, when executed by a control unit, causes the control unit to carry out a method according to the invention.
Ein erfindungsgemäßes Steuergerät zur Betriebsartschaltung eines Hybridfahrzeugs ist eingerichtet ein erfindungsgemäßes Verfahren durchzuführen.An inventive control device for mode switching of a hybrid vehicle is set up to carry out a method according to the invention.
Ein erfindungsgemäßes Hybridfahrzeug umfasst ein erfindungsgemäßes Steuergerät.A hybrid vehicle according to the invention comprises a control unit according to the invention.
Die Vorteile des erfindungsgemäßen Verfahrens ergeben sich in gleicher Weise für das erfindungsgemäße Computerprogrammprodukt, das erfindungsgemäße Steuergerät und das erfindungsgemäße Hybridfahrzeug.The advantages of the method according to the invention result in the same way for the computer program product according to the invention, the control unit according to the invention and the hybrid vehicle according to the invention.
Bevorzugte Ausführungsbeispiele werden anhand der folgenden Figur näher erläutert.Preferred embodiments will be explained in more detail with reference to the following figure.
Im Folgenden wird ein erfindungsgemäßes Verfahren zur Betriebsartschaltung eines Hybridfahrzeugs
- a) Ermitteln eines Beladungszustandes des
Partikelfilters 4 ; - b) Vergleichen des Beladungszustandes mit einem Sollzustand für die Beladung;
- c) Schalten und/oder Beibehaltung der Betriebsart eines
aktiven Verbrennungsmotors 2 , wenn der ermittelte Beladungszustand von dem Sollzustand abweicht.
- a) Determining a loading state of the
particulate filter 4 ; - b) comparing the loading state with a desired state for the loading;
- c) switching and / or maintaining the operating mode of an active
internal combustion engine 2 when the determined loading state deviates from the desired state.
In Schritt c) wird der Elektromotor
Das Hybridfahrzeug
Der Beladungszustand umfasst eine Aschebeladung. Der Sollzustand umfasst einen Grenzwert für die Aschebeladung. Der Beladungszustand des Partikelfilters
Der Grenzwert für die Aschebeladung liegt bei 2 g. The limit for the ash load is 2 g.
Ein so gewählter Grenzwert ermöglicht eine ausreichende Filtereffizienz, um beispielsweise gesetzliche Bestimmungen zur Abgasreinheit beispielsweise in Deutschland einzuhalten.Such a selected limit allows sufficient filter efficiency, for example, to comply with legal requirements for exhaust gas purity, for example in Germany.
Der Beladungszustand umfasst eine Verweilzeit der Asche im Partikelfilter
Die Verweilzeit ist eine Zeit, die eine relevante Teilmenge Asche innerhalb des Partikelfilters
Asche, welche eine Zeit von unterhalb von 2 h innerhalb des Partikelfilters
Eine Verweilzeit von 2 h ist eine Zeit, die das Hybridfahrzeug durchschnittlich für das Zurücklegen von etwa 100 km benötigt.A dwell time of 2 hours is a time that the hybrid vehicle requires on average to travel about 100 km.
