- a first oil pressure stage is provided, in which the oil pressure in response to an operating condition of the internal combustion engine in a first range between a first minimum oil pressure value (oil pressure level) and a first maximum oil pressure value (oil pressure level) fluctuates.
- at least one second oil pressure stage is provided in which the oil pressure fluctuates in a second range between a second minimum oil pressure value (oil pressure level) and a second maximum oil pressure value (oil pressure level) depending on an operating condition of the internal combustion engine.
- the first minimum oil pressure value is less than or equal to the second minimum oil pressure value
- the first maximum oil pressure value is smaller than the second maximum oil pressure value.
- an oil pressure sensor 24 is provided for monitoring the oil pressure.
- the camshaft adjustment varies at different speeds.
- the resulting angular velocity correlates with the oil pressure.
- the angular velocity can be measured by passing through a sufficient adjustment range with maximum activation of the solenoid valve of the camshaft adjuster 18.
- the angular velocity is additionally dependent on the engine speed and oil temperature and should be corrected via this. It is typically in a range that is well and safely measurable with devices available in engine controls.
- the invention it is provided to use the angular velocity of the camshaft adjustment for monitoring the switching mechanism 20 of the oil pump 12 for different oil pressure levels. Due to the tolerance chain regarding in particular oil viscosity, pump characteristics, camshaft adjuster 18 and solenoid valve, not only the angular velocity in the second oil pressure stage that can not be monitored by the remaining oil pressure sensor is determined. Rather, it is provided according to the invention even at the first ⁇ réellech, i. So in both pressure stages, to measure or determine the angular velocity of the camshaft adjustment.

Brennkraftmaschinen verfügen üblicherweise über eine mechanisch angetriebene Ölpumpe. In einigen Anwendungen ist es durch eine entsprechende Stelleinrichtung bzw. einen Schaltmechanismus möglich, zwei oder mehrere Druckstufen mit dieser Ölpumpe mit unterschiedlichem Öldruckniveau bzw. unterschiedlichen Wertebereichen, in denen sich der Öldruck abhängig vom Betriebszustand der Brennkraftmaschine bewegt, anzufahren. Die Ölpumpe verfügt dabei über eine mechanisch wirkende Einrichtung zur Regelung des Öldrucks. Die Verbrennungskraftmaschine benötigt nicht in jedem Betriebskennfeldpunkt den gleichen, hohen Öldruck. Üblicherweise kann der Öldruck zu kleinen Drehzahlen und Lasten hin abgesenkt werden. Erst bei Überschreiten einer entsprechenden, vorbestimmten Last- und Drehzahlschwelle wird auf die höhere zweite Druckstufe geschaltet. Der Öldruck wird somit dem aktuellen Bedarf der Brennkraftmaschinen angepasst. Die Leistungsaufnahme einer solchen zwei oder mehrstufigen Ölpumpe gegenüber einer einstufigen Ölpumpe ist geringer.

Art hinsichtlich des Bauteileaufwandes zu vereinfachen und gleichzeitig die Überwachung der Funktionsfähigkeit des Schaltmechanismus der Ölpumpe zu verbessern.The invention is based on the object, a method of o.g. Simplify the type of component complexity while improving the monitoring of the operability of the switching mechanism of the oil pump.

Advantageous embodiments of the invention are described in the further claims.
Dazu ist es bei einem Verfahren der o.g. Art erfindungsgemäß vorgesehen, dass eine erste Verstellgeschwindigkeit der Nockenwelle durch den Aktuator bestimmt wird, während die erste Öldruckstufe von der Ölpumpe erzeugt wird, wobei für mindestens eine zweite Öldruckstufe eine zweite Verstellgeschwindigkeit der Nockenwelle durch den Aktuator bestimmt wird, während die zweite Öldruckstufe von der Ölpumpe erzeugt wird, wobei mindestens eine Differenz zwischen der ersten und mindestens einer zweiten Verstellgeschwindigkeit bestimmt wird, wobei ein Schaltmechanismus der Ölpumpe zum Umschalten zwischen den Öldruckstufen als in Ordnung eingestuft wird, wenn ein Betrag der Differenz gleich oder größer als ein vorbestimmter Differenzwert ist, und der Schaltmechanismus der Ölpumpe zum Umschalten zwischen den Öldruckstufen als defekt eingestuft wird, wenn ein Betrag der Differenz kleiner als ein vorbestimmter Differenzwert ist.For this purpose, it is provided according to the invention in a method of the aforementioned type that a first adjustment speed of the camshaft is determined by the actuator, while the first oil pressure stage is generated by the oil pump, wherein for at least one second oil pressure stage, a second adjustment speed of the camshaft is determined by the actuator while the second oil pressure stage is generated by the oil pump, wherein at least one difference between the first and at least a second adjustment speed is determined, wherein a switching mechanism of the oil pump for switching between the oil pressure levels is judged to be okay when an amount of the difference is equal to or greater as a predetermined differential value, and the switching mechanism of the oil pump for switching between the oil pressure levels is classified as defective when an amount of the difference is smaller than a predetermined difference value.
Dies hat den Vorteil, dass eine Funktionsfähigkeit des Schaltmechanismus der Ölpumpe ohne zusätzliche Hardware ausschließlich mit vorhandenen Sensoren überwacht wird, wobei die Überwachung unabhängig von Toleranzen hinsichtlich einer Ölviskosität, der Ölpumpe, des Aktuators oder eines Ventils des Aktuators im Ölkreislauf ist.This has the advantage that a functionality of the switching mechanism of the oil pump is monitored without additional hardware exclusively with existing sensors, the monitoring is independent of tolerances on oil viscosity, the oil pump, the actuator or a valve of the actuator in the oil circuit.
Eine vom Betriebszustand der Brennkraftmaschine unabhängige Überwachung der Funktionsfähigkeit des Schaltmechanismus der Ölpumpe ohne Kompensation beispielsweise von drehzahl- oder lastbedingten Schwankungen des Öldruckes erzielt man dadurch, dass die erste und mindestens eine zweite Verstellgeschwindigkeit bei einem identischen Betriebszustand der Brennkraftmaschine bestimmt werden.One independent of the operating condition of the internal combustion engine monitoring the functioning of the switching mechanism of the oil pump without compensation, for example, speed or load-related fluctuations of the oil pressure is achieved in that the first and at least a second adjustment speed are determined in an identical operating condition of the internal combustion engine.
Eine zusätzliche Überwachung der Funktionsfähigkeit der Ölpumpe selbst erzielt man dadurch, dass in einem Betriebszustand der Brennkraftmaschine, während dem die erste Öldruckstufe von der Ölpumpe erzeugt wird, der Öldruck von einem Drucksensor überwacht wird.Additional monitoring of the operability of the oil pump itself is achieved in that in an operating state of the internal combustion engine, during which the first oil pressure stage is generated by the oil pump, the oil pressure is monitored by a pressure sensor.
Eine aktive Diagnose des Schaltmechanismus der Ölpumpe für die verschiedenen Öldruckstufen erzielt man dadurch, dass nach einem Bestimmen der ersten Verstellgeschwindigkeit die Ölpumpe unabhängig vom momentanen Betriebszustand der Brennkraftmaschine auf mindestens eine zweite Öldruckstufe umgeschaltet, die Nockenwelle verstellt und dabei die zweite Verstellgeschwindigkeit bestimmt wird.An active diagnosis of the switching mechanism of the oil pump for the various oil pressure levels achieved by the fact that after determining the first adjustment speed, the oil pump regardless of the current operating state of the internal combustion engine switched to at least a second oil pressure stage, the camshaft adjusted and thereby the second adjustment speed is determined.
Eine Prüfung des Schaltmechanismus der Ölpumpe für die verschiedenen Öldruckstufen bei definierten Zuständen der Brennkraftmaschine erzielt man dadurch, dass die erste und die zweite Verstellgeschwindigkeit bei mindestens einem vorbestimmten Betriebspunkt der Brennkraftmaschine bestimmt werden, wobei unabhängig von dem Betriebspunkt die jeweilige Öldruckstufe umgeschaltet und die Nockenwelle verstellt wird.An examination of the switching mechanism of the oil pump for the different oil pressure levels at defined states of the internal combustion engine is achieved by the fact that the first and second Verstellgeschwindigkeit be determined at least one predetermined operating point of the internal combustion engine, regardless of the operating point, the respective oil pressure level is switched and the camshaft is adjusted ,

Die Erfindung betrifft eine Brennkraftmaschine, wie schematisch in
Der im Motorölkreislauf herrschende Öldruck wird durch die mechanisch angetriebene Ölpumpe 12 im Motorölkreislauf 14 zur Verfügung gestellt. Die Ölpumpe 12 weist einen Schaltmechanismus 20 auf, um zwischen verschiedenen Öldruckstufen umzuschalten. Hierbei ist eine erste Öldruckstufe vorgesehen, bei der der Öldruck in Abhängigkeit von einem Betriebszustand der Brennkraftmaschine in einem ersten Bereich zwischen einem ersten minimalen Öldruckwert (Öldruckniveau) und einem ersten maximalen Öldruckwert (Öldruckniveau) schwankt. Weiterhin ist mindestens eine zweite Öldruckstufe vorgesehen, bei der der Öldruck in Abhängigkeit von einem Betriebszustand der Brennkraftmaschine in einem zweiten Bereich zwischen einem zweiten minimalen Öldruckwert (Öldruckniveau) und eine zweiten maximalen Öldruckwert (Öldruckniveau) schwankt. Hierbei ist der erste minimale Öldruckwert kleiner oder gleich dem zweiten minimalen Öldruckwert und der erste maximale Öldruckwert ist kleiner als der zweite maximale Öldruckwert. Für die erste Öldruckstufe ist ein Öldrucksensor 24 zur Überwachung des Öldruckes vorgesehen.The pressure prevailing in the engine oil circuit oil pressure is provided by the mechanically driven
Je nach Höhe des Öldruckes verstellt sich die Nockenwellenverstellung unterschiedlich schnell. Die sich einstellende Winkelgeschwindigkeit korreliert dabei mit dem Öldruck. Messbar ist die Winkelgeschwindigkeit, indem ein ausreichender Verstellbereich mit maximaler Ansteuerung des Magnetventils des Nockenwellenverstellers 18 durchfahren wird. Die Winkelgeschwindigkeit ist zusätzlich noch abhängig von der Motordrehzahl und Öltemperatur und sollte über diese korrigiert werden. Sie liegt typischerweise in einem Bereich, der mit in Motorsteuerungen verfügbaren Einrichtungen gut und sicher messbar ist.Depending on the level of oil pressure, the camshaft adjustment varies at different speeds. The resulting angular velocity correlates with the oil pressure. The angular velocity can be measured by passing through a sufficient adjustment range with maximum activation of the solenoid valve of the
Erfindungsgemäß ist es vorgesehen, die Winkelgeschwindigkeit der Nockenwellenverstellung zur Überwachung des Schaltmechanismus 20 der Ölpumpe 12 für verschiedenen Öldruckstufen heranzuziehen. Aufgrund der Toleranzkette betreffend insbesondere Ölviskosität, Pumpeneigenschaften, Nockenwellenversteller 18 und Magnetventil wird nicht nur die Winkelgeschwindigkeit in der nicht vom verbleibenden Öldrucksensor überwachbaren zweiten Öldruckstufe bestimmt. Vielmehr ist es erfindungsgemäß vorgesehen auch bei der ersten Ödruckstufe, d.h. also in beiden Druckstufen, die Winkelgeschwindigkeit der Nockenwellenverstellung zu vermessen bzw. zu bestimmen. Ist der Unterschied in den Winkelgeschwindigkeiten ausreichend ausgeprägt, d.h. größer oder gleich einem vorbestimmten Schwellwert, so kann davon ausgegangen werden, dass der Schaltmechanismus 20 der Ölpumpe 12 ordnungsgemäß arbeitet. Die erste, niedrige Öldruckstufe wird vom Drucksensor überwacht. Die zweite Druckstufe wird überwacht, indem der oben beschriebene Vergleich der gemessenen Verstellgeschwindigkeit der Nockenwellenverstelleinrichtung 18 bei verschiedenen Öldruckstufen ausgewertet wird. Ist die Geschwindigkeit der Nockenwellenverstellung in beiden Öldruckstufen identisch, kann davon ausgegangen werden, dass der Schaltmechanismus 20 der Ölpumpe 12 nicht ordnungsgemäß arbeitet. Die Ölpumpe 12 kann in diesem Fall nur einen Druck bzw. eine Öldruckstufe einstellen.According to the invention, it is provided to use the angular velocity of the camshaft adjustment for monitoring the
In einer bevorzugten Ausführung des erfindungsgemäßen Verfahrens wird in einem konstanten Betriebspunkt zunächst die erste und danach die zweite Öldruckstufe gefahren. Der Ausdruck "konstanter Betriebspunkt" bezeichnet hierbei eine Betriebszustand der Brennkraftmaschinen, bei dem nicht notwendigerweise eine der zweiten, höheren Öldruckstufen und auch nicht notwendigerweise eine Nockenwellenverstellung erforderlich ist. Mit anderen Worten werden die Öldruckstufe und die Nockenwellenverstellung unabhängig vom momentanen Betriebszustand der Brennkraftmaschine eingestellt bzw. verändert. In beiden Druckstufen wird die Verstellgeschwindigkeit der Nockenwellenverstellung vermessen bzw. bestimmt und ausgewertet bzw. die Differenz bestimmt. Die Abhängigkeiten zur Öltemperatur und zum Last-Drehzahlpunkt werden auf diese Weise ausgeklammert. Die Auswirkungen auf die Emissionen durch die nicht optimale Nockenwellenposition während der Vermessung werden durch eine geeignete Wahl des konstanten Betriebspunktes beachtet.In a preferred embodiment of the method according to the invention, first the first and then the second oil pressure stage are driven at a constant operating point. The term "constant operating point" here refers to an operating state of the internal combustion engine in which not necessarily one of the second, higher oil pressure stages and also not necessarily a camshaft adjustment is required. In other words, the oil pressure stage and the camshaft adjustment are adjusted or changed independently of the current operating state of the internal combustion engine. In both pressure stages, the adjustment speed of the camshaft adjustment is measured or determined and evaluated or determines the difference. The dependencies on the oil temperature and the load-speed point are excluded in this way. The impact on the Emissions due to the non-optimal camshaft position during the measurement are taken into account by a suitable choice of the constant operating point.
Der Kosten- bzw. Bauraumnachteil eines zweiten Öldrucksensors für die zweite Öldruckstufe werden eingespart, da für die Überwachung, ob die zweite Druckstufe erreicht wird, kein zusätzlicher Öldrucksensor erforderlich ist. Es wird eine Kostenneutralität erzielt, da die Diagnose der zweiten Öldruckstufe mittels bereits in der Verbrennungskraftmaschine vorhandenen Aktoren und Sensoren basiert.The cost or installation space disadvantage of a second oil pressure sensor for the second oil pressure stage can be saved because no additional oil pressure sensor is required for monitoring whether the second pressure level is reached. A cost neutrality is achieved because the diagnosis of the second oil pressure stage is based on already existing in the internal combustion engine actuators and sensors.

In einem vierten Schritt 110 "Ölpumpe in Druckstufe 2 => Anforderung Nockenwellen Sollsprung" wird die Ölpumpe derart betrieben, dass diese eine zweite Druckstufe im Ölkreislaufsystem der Brennkraftmaschine zur Verfügung stellt, wobei sich der im Ölkreislaufsystem der Brennkraftmaschine ergebende Druck unterschiedlich von dem entsprechenden Druck bei der ersten Druckstufe ist, und es wird erneut die Nockenwelle verstellt. In einem fünften Schritt 112 "Vermessung Nockenwelle" wird eine Verstellgeschwindigkeit 2 der Nockenwelle bei der Verstellung als Winkelgeschwindigkeit ω [°/ms] für die zweite Druckstufe bestimmt. In einem sechsten Schritt 114 "Verstellgeschwindigkeit 2 > Verstellgeschwindigkeit 1" wird geprüft, ob die Verstellgeschwindigkeit 2 für die zweite Druckstufe größer ist als die Verstellgeschwindigkeit 1 für die erste Druckstufe. Sofern die Ölpumpe bzw. das Stellglied für die Druckstufen korrekt arbeitet und in der zweiten Druckstufe einen höheren Druck in dem Ölkreislaufsystem der Brennkraftmaschine erzeugt als in der ersten Druckstufe, muss die Verstellgeschwindigkeit 2 größer sein als die Verstellgeschwindigkeit 1. Somit ist umgekehrt dies ein Indiz für eine korrekt arbeitende Ölpumpe bzw. Umschaltung zwischen den Druckstufen. Daher wird von dem sechsten Schritt 114 über einen dritten Zweig 118 "ja" zu einem siebten Schritt 116 "Test abgeschlossen, Stellglied für Druckstufen der Ölpumpe in Ordnung" gesprungen, falls in Schritt 114 das Ergebnis der Prüfung "Verstellgeschwindigkeit 2 > Verstellgeschwindigkeit 1 ?" ja ist. Ist dies jedoch nicht der Fall, so wird über einen vierten Zweig 120 "nein" zu einem achten Schritt 122 "Test abgeschlossen, Stellglied für Druckstufen der Ölpumpe nicht in Ordnung" gesprungen.If all tested parameters are within a predetermined range, then a
