Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Reduktion des Abstellschlagens eines Verbrennungsmotors.The invention relates to a Method and device for reducing the impact of parking of an internal combustion engine.
Bei Fahrzeugen mit Otto- oder Dieselmotoren, insbesondere bei Verbrennungsmotoren mit hohen Verdichtungsverhältnissen, tritt gewöhnlich beim Abstellen ein starkes Rückstellmoment auf (Abstellschlagen), welches sich negativ auf den Fahrkomfort auswirkt.For vehicles with petrol or diesel engines, especially in internal combustion engines with high compression ratios, usually occurs a strong restoring torque when parking on (parking knock), which has a negative impact on driving comfort.
Es ist bekannt, durch eine elektropneumatisch betätigte Abstellklappe im Ansaugrohr beim Abstellen des Verbrennungsmotors eine Ansaugluftzufuhr zu unterbinden. Dadurch kann der Verbrennungsmotor weich auslaufen und ein deutlicher Komfortgewinn erzielt werden. Nachteilig ist jedoch der hohe konstruktive Aufwand und die damit verbundenen hohen Kosten.It is known to be electropneumatic actuated Parking flap in the intake pipe when switching off the combustion engine to prevent an intake air supply. This allows the internal combustion engine run out softly and a clear gain in comfort can be achieved. The disadvantage, however, is the high design effort and the consequent associated high costs.
Der Erfindung liegt daher das technische Problem zugrunde, ein Verfahren und eine Vorrichtung zu schaffen, mit welchem das abrupte Schlagen des Verbrennungsmotors beim Abstellen mit geringem konstruktiven Aufwand reduziert wird.The invention therefore has the technical problem to create a method and an apparatus with which the abrupt beating of the internal combustion engine when turning it off with little design effort is reduced.
Die Lösung des Problems ergibt sich durch die Gegenstände mit den Merkmalen der Ansprüche 1 und 5. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution to the problem arises through the objects with the features of claims 1 and 5. Further advantageous embodiments of the invention result itself from the subclaims.
Hierfür wird durch eine mit einem Verbrennungsmotor kuppelbare Elektromaschine ein geregeltes Moment aufgebracht, welches dem Abstellschlagen des Verbrennungsmotors kurzzeitig entgegenwirkt. Dadurch ist eine bessere Unterdrückung des Abstellschlagens bei einem geringeren konstruktiven Aufwand erzielbar als durch die bekannten, konstruktiv aufwendigen Abstellklappen in der Ansaugstrecke des Verbrennungsmotors. Durch den kurzzeitigen Einsatz ist der Energiebedarf der Elektromaschine gering.For this, one with one Internal combustion engine detachable electric machine a regulated moment applied, which is the shutdown of the internal combustion engine counteracts briefly. This is a better suppression of the Abschlagschlagens achievable with less design effort than through the well-known, constructively complex flaps in the intake section of the internal combustion engine. Due to the short-term Use, the energy requirement of the electric machine is low.
In einer bevorzugten Ausführungsform
wird durch einen Sensor eine Drehschwingung und/oder ein Drehmoment
und/oder die Richtung der Kurbelwelle
In einer bevorzugten Ausführungsform wird der Verbrennungsmotor durch die Elektromaschine angelassen, wobei die Elektromaschine als Startergenerator ausgebildet ist. Die Funktionsübernahme der Abstellschlagunterdrückung durch den Startergenerator sind keine zusätzlichen Bauelemente notwendig, was zu einer weiteren, relativen Kostenreduktion führt. Nach erfolgtem Anlassen wirkt die Elektromaschine als Generator. Der Energieverbrauch durch die als Motor wirkende Elektromaschine ist auf den Anlass- und den Abstellvorgang begrenzt.In a preferred embodiment the internal combustion engine is started by the electric machine, wherein the electric machine is designed as a starter generator. The takeover of the Abstellschlagunterdrückung no additional components are necessary due to the starter generator, which leads to a further, relative cost reduction. To When started, the electric machine acts as a generator. The Energy consumption due to the electric machine acting as a motor limited to the starting and stopping process.
In einer weiteren Ausführungsform
ist das durch die Elektromaschine aufgebrachte Anlassmoment geregelt
und/oder gesteuert, so dass ein sanftes Anlassen des Verbrennungsmotors
realisiert wird. Auch beim Anlassen des Verbrennungsmotors kann
das Aufbringen des Anlassmomentes zu einem mechanischen Schlag führen. Ein
für den
Anlassvorgang geeignet Anlassmoment ist beispielsweise durch Versuche
im Vorfeld bestimmbar und die Elektromaschine entsprechend steuerbar.
Andererseits ist es auch denkbar, im Anlassvorgang die Drehschwingung
und/oder das Drehmoment und/oder die Richtung der Kurbelwelle
Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt eine schematische Darstellung einer Vorrichtung zur Reduzierung des Abstellschlagens.The invention is described below of a preferred embodiment explained in more detail. The only figure shows a schematic representation of a device to reduce the striking.
Beim Abstellen des Verbrennungsmotors
In der dargestellten Ausführungsform
wird zum Anlassen des Verbrennungsmotors
In der gezeigten Anordnung der Elemente
ist es denkbar, den Verbrennungsmotor
Außer im Anlass- und im Abstellvorgang wird die Elektromaschine als Generator betrieben oder abgeschaltet. Ein durchgängiger motorischer Betrieb der Elektromaschine, beispielsweise als aktive Dämpfung, ist aufgrund des hohen Energiebedarfs nur in Ausnahmen vorteilhaft. Dagegen spielt der Energiebedarf durch den zusätzlichen kurzzeitigen Betrieb der Elektromaschine im Abstellvorgang aufgrund der zeitlichen Begrenzung nur eine untergeordnete Rolle. Das Verfahren und/oder die Vorrichtung sind daher vorteilhaft für eine Verbesserung des Fahrkomforts einsetzbar.Except when starting and stopping the electric machine is operated as a generator or switched off. A consistent one motor operation of the electric machine, for example as active damping, is only advantageous in exceptional cases due to the high energy requirement. In contrast, the energy requirement plays through the additional short-term operation the electric machine in the shutdown process due to the time limit only a subordinate role. The method and / or the device are therefore advantageous for an improvement in driving comfort can be used.
