Abstract
Description
Die Erfindung betrifft ein Verfahren zur Erkennung einer Falschbetankung einer Brennkraftmaschine eines Kraftfahrzeuges.The The invention relates to a method for detecting misfuel an internal combustion engine of a motor vehicle.
Beim Betanken eines Kraftfahrzeuges kann es vorkommen, dass das Kraftfahrzeug versehentlich mit dem falschen Treibstoff betankt wird. Dies kann unerwünschte Folgen haben. Wird beispielsweise Diesel statt Benzin getankt, so kann die Brennkraftmaschine nicht zünden und das Kraftfahrzeug bleibt liegen. Wird Benzin statt Diesel getankt, so verbrennt der Treibstoff zu heiß und es kommt zu unkontrollierten Zündungen mit hohen Druckspitzen, die als Klopfen hörbar und spürbar sind. Dies kann zu einer Schädigung der Brennkraftmaschine führen. Außerdem sind auch Fehlbetankungen mit anderen Treibstoffarten, wie beispielsweise Alkohol denkbar.At the Refueling of a motor vehicle, it may happen that the motor vehicle accidentally refueled with the wrong fuel. This can have undesirable consequences to have. For example, if diesel fueled instead of gasoline, so can Do not ignite the engine and the motor vehicle remains. Is gasoline fueled instead of diesel, so the fuel burns too hot and it comes to uncontrolled ignitions with high pressure peaks that are audible and palpable as a knock. This can damage the Internal combustion engine lead. Furthermore are also misfuelling with other fuel types, such as Alcohol conceivable.

der
Aufgabe der Erfindung ist es, eine Falschbetankung eines Kraftfahrzeuges zu erkennen und durch eine Falschbetankung verursachte Schäden an der Brennkraftmaschine und dem Kraftfahrzeug zu verhindern.task The invention is a misfuelling of a motor vehicle to recognize and by a wrong refueling caused damage to the To prevent internal combustion engine and the motor vehicle.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass in einem ersten Schritt ein Signal eines Klopfsensors einer Brennkraftmaschine des Kraftfahrzeuges erfasst wird. In einem zweiten Schritt wird eine Falschbetankung dann erkannt, wenn die Auswertung des Signals des Kopfsensors ein abnormales Geräuschverhalten (im Weiteren vereinfacht „Klopfen" genannt) der Brennkraftmaschine erkennt. Typischerweise kommen als Klopfsensoren Körperschall- oder Beschleunigungsaufnehmer zum Einsatz.The The object is achieved in that in a first step, a signal of a knock sensor of an internal combustion engine of the motor vehicle is detected. In a second step, a Incorrect refueling then detected when the evaluation of the signal of the Head sensor an abnormal noise behavior (hereinafter simply referred to as "knocking") of the internal combustion engine recognizes. Typically, as knock sensors, structure-borne sound or accelerometer is used.
Zur Klopferkennung werden die für das Klopfen charakteristischen Schwingungen durch einen oder mehrere Körperschallaufnehmer, die Klopfsensoren, in elektrische Signale umgewandelt und einer Auswerteeinheit zugeführt.to Knock detection will be the for the knocking characteristic oscillations by one or more Acoustic emission sensor, the knock sensors, converted into electrical signals and an evaluation unit fed.
Dort erfolgt für jeden Zylinder und jede Verbrennung in einem entsprechenden Auswertealgorithmus die Klopferkennung.There done for every cylinder and every combustion in a corresponding evaluation algorithm the knock detection.
Wird eine Brennkraftmaschine statt mit Diesel mit Benzin betrieben, so führt dieser falsche Treibstoff zu einem Klopfen der Brennkraftmaschine. Dieses durch Fehlbetankung verursachte Klopfen unterscheidet sich von dem z.B. aus der Kaltstartphase bekannten Nageln eines Dieselmotors. Das Klopfen kann die Brennkraftmaschine schädigen. Mit dem erfindungsgemäßen Verfahren ist eine Erkennung einer Falschbetankung allein aufgrund der Klopferkennung möglich. Eine physikalische oder chemische Untersuchung des Kraftstoffes ist nicht nötig. Besonderer Vorteil dieser Methode liegt darin, dass die Fehlbetankung anhand ihrer unerwünschten Wirkung erkannt wird. Dieses Verfahren kann mit vielfach bereits serienmäßig vorhandenen Bauteilen durchgeführt werden. Damit ist es möglich, dieses Verfahren durch Überspielen neuer Software kostengünstig, sowohl in Neuwagen, als auch in bereits ausgelieferten Fahrzeugen, einzusetzen.Becomes an internal combustion engine instead of running diesel with gasoline, so leads this wrong fuel to a knocking of the internal combustion engine. This knocking caused by misfueling is different from that e.g. from the cold start phase known nailing a diesel engine. The knocking can damage the engine. With the method according to the invention is a detection of misfueling solely due to the knock detection possible. A physical or chemical analysis of the fuel is not necessary. The particular advantage of this method is that the misfueling based on their unwanted Effect is detected. This procedure can already be used many times standard available Components performed become. This makes it possible this method by dubbing new software cost-effective, both in new cars and in already delivered vehicles, use.
In einer Ausführungsform wird ein Umwelt- oder Betriebsparameter der Brennkraftmaschine erfasst. Umwelt- oder Betriebsparameter geben Informationen über die Randbedingungen unter denen die Brennkraftmaschine arbeitet. Solche Randbedingungen können Einfluss auf das Klopfverhalten der Brennkraftmaschine haben. Beispielsweise wirkt sich eine Falschbetankung im Winter langsamer aus, als im Sommer. Wird eine solche Randbedingung erfasst, so kann ihr Einfluss auf das Klopfverhalten der Brennkraftmaschine berücksichtigt werden. Dies erhöht die Qualität des Verfahrens und senkt die Fehleranfälligkeit.In an embodiment An environmental or operating parameter of the internal combustion engine is detected. Environmental or operating parameters provide information about the Boundary conditions under which the internal combustion engine works. Such Boundary conditions can Influence on the knocking behavior of the internal combustion engine have. For example Misleading refueling will be slower in winter than in winter Summer. If such a boundary condition is detected, then its influence can taken into account the knocking behavior of the internal combustion engine become. This increases the quality of the procedure and reduces the susceptibility to errors.
Insbesondere können mehrere Parameter erfasst und zur Erkennung einer Falschbetankung herangezogen werden. Besonders günstig ist es, bereits vorhandene Sensoren zur Erfassung der Parameter einzusetzen. Ebenso können im Steuergerät vorhandene relevante Rechengrößen verwendet werden. Derartige Parameter und/oder Rechengrößen können beispielsweise die Drehzahl der Brennkraftmaschine, das Drehmoment der Brennkraftmaschine, Einspritzmenge des Treibstoffs die Geschwindigkeit des Fahrzeugs und/oder die Außentemperatur sein. Die Auswertung des Signals des Klopfsensors kann aufgrund dieser Randbedingungen genauer erfolgen. Die Gefahr einer Fehlinterpretation der erfassten Daten wird reduziert.Especially can recorded several parameters and used to detect misfuelling become. Very cheap it is already existing sensors to capture the parameters use. Likewise present in the control unit relevant arithmetic variables are used. Such parameters and / or arithmetic variables can, for example, the speed the internal combustion engine, the torque of the internal combustion engine, injection quantity of fuel, the speed of the vehicle and / or the outside temperature be. The evaluation of the signal of the knock sensor may be due to these boundary conditions are more accurate. The danger of a misinterpretation the collected data is reduced.
In einer Ausführungsform wird die Falschbetankung nach ihrer Erkennung signalisiert. Diese Signalisierung kann an den Fahrer als optisches oder akustisches Signal erfolgen oder als Steuersignal an eine Steuereinrichtung des Fahrzeuges weitergegeben werden. Wird die Falschbetankung an den Fahrer signalisiert, so ist der Fahrer informiert und kann entsprechend reagieren. Er kann z.B. das Kraftfahrzeug parken und abschleppen lassen oder ohne Volllastfahrt die nächste Werkstatt anfahren und den Tank leeren lassen. Damit kann ein Folgeschaden vermieden werden.In one embodiment, the misfueling is signaled after its detection. This signaling can be done to the driver as an optical or acoustic signal or passed as a control signal to a control device of the vehicle. If the wrong fueling signaled to the driver, so the driver is informed and can respond accordingly. He can eg the driving Park and tow the vehicle or drive to the next workshop without full load and empty the tank. Thus a consequential damage can be avoided.
In einer Ausführungsform wird nach Erkennung einer Falschbetankung eine Sicherheitsreaktion ausgelöst. Ziel dieser vom Kraftfahrzeug ausgelösten Sicherheitsreaktion ist es, Folgeschäden durch die Falschbetankung zu verhindern. Eine solche Sicherheitsreaktion kann als eine Begrenzung des Drehmoments der Brennkraftmaschine ausgeführt sein.In an embodiment becomes a safety reaction after detection of a misfueling triggered. The aim of this triggered by the motor vehicle safety reaction is it, consequential damage to prevent the misfuelling. Such a security reaction can be considered as limiting the torque of the internal combustion engine accomplished be.
In einer Ausführungsform ist die Sicherheitsreaktion als eine Reduzierung der Last der Brennkraftmaschine ausgeführt. Beispielsweise schaltet das Getriebe der Brennkraftmaschine in einen Gang mit günstigerer (höherer) Übersetzung oder es werden zusätzliche Verbraucher wie Innenraumlüftung oder Nebenaggregate der Brennkraftmaschine (Generator, Aktoren) abgeschaltet.In an embodiment is the safety reaction as a reduction of the load of the internal combustion engine executed. For example, the transmission of the internal combustion engine switches into one Gang with cheaper (higher) translation or it will be additional Consumers like indoor ventilation or Auxiliary units of the internal combustion engine (generator, actuators) switched off.
In einer Ausführungsform ist die Sicherheitsreaktion als eine Abschaltung der Brennkraftmaschine ausgeführt. Damit wird die Zufuhr des falschen Treibstoffes beendet. Die Brennkraftmaschine wird nicht weiter belastet.In an embodiment is the safety reaction as a shutdown of the internal combustion engine executed. This stops the supply of the wrong fuel. The internal combustion engine will not be charged further.
