Aufgabe der ErfindungTask of invention
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bereitzustellen, bei dem auch solche Tuning-Maßnahmen, die nicht direkt das Steuergerät der Brennkraftmaschine betreffen, zuverlässig erkannt werden können.task the present invention is to provide a method which includes such tuning measures, not directly the controller of the Affect internal combustion engine, can be reliably detected.

Weitere Lösungen sind in nebengeordneten Patentansprüchen angegeben, die ein Computerprogramm, ein elektrisches Speichermedium sowie eine Steuer- und/oder Regeleinrichtung betreffen. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind in Unteransprüchen angegeben.These The object is achieved by a method having the features of the claim 1 solved. Other solutions are given in the independent claims which are a computer program, an electrical storage medium and a control and / or regulating device affect. Advantageous embodiments of the method according to the invention are in dependent claims specified.
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Verfahren ist speziell darauf gerichtet, solche Tuning-Maßnahmen zu erkennen, welche nicht durch eine Veränderung beispielsweise der entsprechenden Kennfelder im Steuergerät herbeigeführt werden, sondern die durch Manipulationen an Einrichtungen der Brennkraftmaschine außerhalb des Steuergeräts bewirkt werden. Hierzu gehört beispielsweise, bei einer Brennkraftmaschine mit einem Common-Rail-System, eine Veränderung einer Kennlinie eines Drucksensors, mit dem der Druck im Rail erfasst wird. Weitere mögliche Tuning-Maßnahmen, die von dem erfindungsgemäßen Verfahren erkannt werden können, bestehen im Vorschalten eines Tuning-Geräts vor die Einspritzventile, um bei diesen eine zusätzliche Einspritzung zu bewirken.The inventive method is specifically aimed at identifying such tuning measures which not by a change For example, the corresponding maps in the controller are brought about, but by manipulation of facilities of the internal combustion engine outside of the control unit be effected. Which also includes For example, in an internal combustion engine with a common rail system, a change a characteristic curve of a pressure sensor, with which the pressure in the rail detected becomes. Other possible Tuning measures, those of the method according to the invention can be recognized consist in the upstream of a tuning device before the injectors to in these an additional Effect injection.
Alle diese Tuning-Maßnahmen haben gemeinsam, dass eine Ist-Leistungsgröße, beispielsweise die Leistung, das Drehmoment oder die eingespritzte Kraftstoffmenge, von der im Steuergerät vorgegebenen bzw. von diesem bereitgestellten Soll-Leistungsgröße abweichen. Durch eine Auswertung dieser Abweichung können derartige Tuning-Maßnahmen zuverlässig erkannt werden, und es kann auch zuverlässig unterschieden werden, ob die Abweichung von einer bewussten Tuning-Maßnahme herrührt oder auf einen Defekt eines Teils der Brennkraftmaschine zurückzuführen ist. Eine auf diese Weise bereit gestellte Plausibilitätsgröße gestattet es, bei erkannter externer Tuning-Maßnahme bestimmte Maßnahmen zu ergreifen, die die Brennkraftmaschine vor Beschädigungen schützen.All these tuning measures have in common that an actual performance size, for example the power, the torque or the injected fuel quantity, from that in the control unit predetermined or provided by this target performance variable. By evaluating this deviation, such tuning measures can reliable be recognized and it can also be reliably distinguished whether the deviation is due to a deliberate tuning measure or to a defect of a Part of the internal combustion engine is due. A plausibility value provided in this way allows if any external tuning action is detected, certain actions to seize the internal combustion engine from damage protect.
Die Art bzw. das Muster der Abweichung der Ist-Leistungsgröße von der Soll-Leistungsgröße ist dabei ganz spezifisch für bestimmte Tuning-Maßnahmen. Aus in unterschiedlichen Betriebspunkten erfassten Abweichungen kann ein Abweichungsmuster erstellt werden. Ein solches Abweichungsmuster ist bei einer Veränderung der Kennlinie eines Raildrucksensors anders als bei der Generierung zusätzlicher Einspritzungen von Kraftstoff. Derartige spezifische Abweichungsmuster können beispielsweise in Labortests erfasst und im Steuergerät der Brennkraftmaschine abgespeichert werden, so dass sie für die Korrelierung mit erfassten Abweichungsmustern und somit zur Erkennung externer Tuning-Maßnahmen jederzeit zur Verfügung stehen. Hierdurch wird die Zuverlässigkeit des erfindungsgemäßen Verfahrens erhöht. Grundsätzlich denkbar und besonders einfach ist aber der Vergleich der erfassten Abweichung mit einer Mindestabweichung.The Type or pattern of deviation of the actual power of the Target performance is included very specific for certain tuning measures. From deviations recorded at different operating points a deviation pattern can be created. Such a deviation pattern is changing the characteristic of a rail pressure sensor differently than in the generation additional injections of fuel. Such specific deviation patterns may be, for example recorded in laboratory tests and stored in the control unit of the internal combustion engine be so for them the correlation with recorded deviation patterns and thus for Detection of external tuning measures available at any time stand. As a result, the reliability of the method according to the invention elevated. in principle conceivable and particularly simple is the comparison of the recorded Deviation with a minimum deviation.
Zur Ermittlung der Ist-Leistungsgröße kann ein Schätz- oder auch ein Beobachter-Verfahren angewendet werden, bei dem bestimmte aktuelle Betriebsparameter der Brennkraftmaschine verarbeitet werden. Zu diesen Betriebsparametern gehört beispielsweise eine Drehzahl einer Kurbelwelle, ein Druck in mindestens einem Brennraum, und/oder eine eingespritzte Kraftstoffmenge. Möglich ist aber auch eine direkte Erfassung der Ist-Leistungsgröße durch einen entsprechenden Sensor, beispielsweise durch die Messung des an der Kurbelwelle anliegenden Drehmoments.To determine the actual power quantity, an estimation or also an observer method can be used in which certain current operating parameters of the internal combustion engine are processed. These operating parameters include, for example, a rotational speed of a crankshaft, a pressure in at least one combustion chamber, and / or an injected fuel quantity. But also possible is a direct detection of the actual power size by a corresponding sensor, for example by measuring the torque applied to the crankshaft.
Die Ist-Leistungsgröße kann auch ein "indirekter Parameter" sein, also eine solche Größe, die mit der Leistung lediglich zusammenhängt. Hierzu gehört beispielsweise, zumindest in bestimmten Betriebszuständen der Brennkraftmaschine, die in die Brennräume der Brennkraftmaschine gelangende Kraftstoffmenge, oder die Beschleunigung des Fahrzeugs, abgeleitet aus dessen Geschwindigkeit.The Actual performance size can also an "indirect Parameter ", so a size that with the performance is merely related. Which also includes For example, at least in certain operating conditions of Internal combustion engine, which enters the combustion chambers of the internal combustion engine amount of fuel passing, or the acceleration of the vehicle, derived from its speed.
Die Abweichung der Ist-Leistungsgröße von der Soll-Leistungsgröße kann einfach und genau durch einen Differenzenfilter ermittelt werden. Ein Entprellglied kann genutzt werden, um eine gewünschte statistische Sicherheit bezüglich des Vorhandenseins einer externen Tuningmaßnahme durch Manipulationsgeräte zu erreichen.The Deviation of the actual power quantity from the Target power size can be determined simply and accurately by a difference filter. A debouncing member can be used to provide a desired statistical Safety Regarding to achieve the presence of an external Tuningmaßnahme by manipulation devices.

Der einfachste Ansatz für die Auswertung wäre der Vergleich mit einer Mindestabweichung. Alternativ ist jedoch auch denkbar, die Abweichung über den gesamten Arbeitsbereich zu ermitteln. Dies würde bedeuten, dass gewartet werden muss, bis sich das Fahrzeug mindestens einmal in jedem Fahrzustand befand. Anschließend würde das erhaltene Abweichungsmuster mit bekannten im Steuergerät gespeicherten Mustern korreliert werden.Of the simplest approach for the evaluation would be the comparison with a minimum deviation. Alternatively, however also conceivable, the deviation over to determine the entire work area. This would mean that waited must be until the vehicle at least once in each driving condition was. Subsequently that would be obtained deviation pattern with known stored in the control unit Patterns are correlated.
