Description

Die Erfindung betrifft ein Verfahren zur Einstellung eines Stellwinkels einer Klappvorrichtung einer Ansaugvorrichtung gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a method for adjusting a setting angle a folding device of a suction device according to the features of the preamble of claim 1.

In einer Saugrohranlage einer Brennkraftmaschine ist in jedem Ansaugrohr mindestens eine Klappe, insbesondere eine Drallklappe, senkrecht zum Anströmquerschnitt des Saugrohrs drehbar an einer Klappenwelle angeordnet. Die Klappen sind dabei in einem luftdichten Gehäuse angebracht. Der Einsatz einer kontinuierlich verstellbaren Klappvorrichtung bietet dabei mehrere Vorteile. Einerseits kann gewährleistet sein, dass die Auflagen der verschärften Abgasgesetzgebung eingehalten werden, andererseits kann die in die Brennkraftmaschine einzuspritzende Kraftstoffmenge reduziert werden.In an intake manifold of an internal combustion engine is in each intake manifold at least one flap, in particular a swirl flap, perpendicular to inflow cross of the suction tube rotatably disposed on a flap shaft. The flaps are mounted in an airtight housing. The use a continuously adjustable folding device offers several advantages. On the one hand, it can be guaranteed that the conditions the aggravated Emissions legislation can be met, on the other hand, in the Internal combustion engine to be injected fuel quantity can be reduced.

Mit Hilfe einer verstellbaren Klappvorrichtung lässt sich die in die Brennkraftmaschine zugeführte Verbrennungsluft, abhängig vom Betriebspunkt der Brennkraftmaschine, in einfacher Weise regulieren. Die Ansteuerung der Klappvorrichtung auf einen bestimmten Stellwinkel erfolgt dabei mittels eines Aktors. Die exakte Ansteuerung der Klappvorrichtung auf einen bestimmten Stellwinkel wird aber dadurch erschwert, dass diverse Störeffekte, wie z. B. ein existierendes Spiel in den jeweiligen Lagerungen, oder zwischen der Klappe und der Klappenwelle, auf den Stellwinkel der jeweiligen Klappe einen unterschiedlich starken Einfluss haben. Der Einfluss dieser Störeffekte auf den Stellwinkel der einzelnen Klappen kann dabei bis zu 3° bis 4° betragen.With Help of an adjustable folding device can be in the internal combustion engine supplied combustion air, dependent from the operating point of the internal combustion engine, to regulate in a simple manner. The Control of the folding device to a certain angle takes place by means of an actuator. The exact control of the folding device a certain angle but is complicated by the fact that various parasitics, such as B. an existing game in the respective bearings, or between the flap and the flap shaft, on the angle of the respective flap have a different influence. The influence of these disturbing effects on the adjustment angle of the individual flaps can be up to 3 ° to 4 °.

Die der vorliegenden Erfindung zu Grunde liegende Aufgabe besteht nun darin, den Einfluss von Störeffekten, die eine exakte Ansteuerung der Klappen auf einen bestimmten Stellwinkel erschweren, zu verringern.The The object underlying the present invention is now therein, the influence of disruptive effects, the exact control of the flaps on a certain angle complicate, reduce.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.These The object is achieved by the Characteristics of claim 1 solved. Advantageous embodiments The invention are characterized in the subclaims.

Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, dass durch eine Ermittlung eines optimalen Stellwinkels der Klappvorrichtung ein Großteil der Störeffekte, die Einfluss auf die Einstellgenauigkeit des Stellwinkels der Klappvorrichtung haben, verringert werden kann.Of the obtained with the invention advantage is in particular that by determining an optimum adjustment angle of the folding device a big part the disturbing effects, which have an influence on the setting accuracy of the setting angle of the folding device, can be reduced.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass der Differenzwinkel zwischen dem optimalen Stellwinkel der Klappvorrichtung und dem Stellwinkel, bei dem ein Element der Klappvorrichtung auf einen Anschlag trifft, abgespeichert wird. Dadurch ergibt sich der Vorteil, dass bei einem Wechsel des Aktors der gespeicherte Stellwinkel auch für den neuen Aktor unmittelbar verwendbar ist.A further advantageous embodiment of the invention is that the difference angle between the optimum adjustment angle of Folding device and the adjustment angle at which an element of the folding device encounters a stop, is stored. This results the advantage that when a change of the actuator of the stored Adjustment angle also for the new actuator is directly usable.

Dabei hat es sich als vorteilhaft erwiesen, als Ausgangsposition der Klappvorrichtung die Position zu wählen, bei der ein Einströmen von Verbrennungsluft in die Brennkraftmaschine verhindert wird. In einer solchen geschlossenen Position haben geringfügige Änderungen der Klappen von dieser Position einen größeren Einfluss auf die der Brennkraftmaschine zugeführte Verbrennungsluft, als die Abweichungen von der Position bei vollkommen geöffneten Klappen.there It has proved to be advantageous as the starting position of the folding device to choose the position at the one inflow combustion air is prevented in the internal combustion engine. In such a closed position will have minor changes the flaps from this position have a greater impact on the Internal combustion engine supplied Combustion air, as the deviations from the position at perfect open Flaps.

Weiterhin können mittels des Anschlags Fehler während des Betriebs der Koppelstange identifiziert werden. Hierzu wird der Stellwinkelwert der Klappvorrichtung durch einen Aktor solange verändert, bis mindestens ein Element der Klappvorrichtung den Anschlag trifft. Beim Treffen des Anschlags wird ein elektrisches Signal ausgelöst, aufgrund dessen der Aktor den Stellwinkelwert der Klappvorrichtung nicht mehr verändert. Ein Fehler im Betrieb der Klappvorrichtung wird dadurch erkannt, dass zyklisch der Anschlag angefahren wird, dessen Soll-Stellwinkel im Steuergerät oder im Lagesensor abgespeichert ist. Weicht der ermittelte Ist-Stellwinkelwert stärker als ein zulässiger Toleranzwert vom Soll-Stellwinkelwert ab, so wird eine Fehlermeldung ausgelöst.Farther can by means of the stop error during the operation of the coupling rod can be identified. For this purpose is the adjusting angle value of the folding device by an actuator while changed until at least one element of the folding device hits the stop. When the stop hits an electrical signal is triggered, due of which the actuator is not the angle value of the folding device more changed. An error in the operation of the folding device is detected by that the stop is cyclically approached, the setpoint angle in the control unit or stored in the position sensor. If the determined actual adjustment angle value deviates more than a legal one Tolerance value from the setpoint angle value, then an error message triggered.

Einzelheiten der Erfindung werden anhand der Zeichnung näher erläutert. Dabei zeigt:details The invention will be explained in more detail with reference to the drawing. Showing:

1: ein Flussdiagram zur Bestimmung des optimalen Stellwinkels der Klappvorrichtung. 1 : a flow chart for determining the optimal adjustment angle of the folding device.

1 zeigt ein Flussdiagramm zur Bestimmung des optimalen Stellwinkels der Klappvorrichtung. Im Schritt S1 wird die Klappvorrichtung in eine vorgebbare Position verstellt. Dabei hat es sich als vorteilhaft erwiesen, dass die Klappen in eine geschlossene Position, bei der keine Verbrennungsluft durch das Saugrohr zur Brennkraftmaschine strömen kann, verstellt werden. Im Idealfall, ohne diverse Störeffekte, die auf die Klappen wirken, müssten bei der geschlossenen Position der Klappvorrichtung die Stellwinkel der einzelnen Klappen jeweils gleich sein. 1 shows a flow chart for determining the optimal adjustment angle of the folding device. In step S1, the folding device is adjusted to a predeterminable position. It has proved to be advantageous that the flaps are adjusted to a closed position in which no combustion air can flow through the intake manifold to the engine. In the ideal case, without various disturbing effects that act on the flaps, the setting angle of the individual flaps would have to be the same in the closed position of the folding device.

Im Schritt S10 werden daher die Stellwinkel der einzelnen Klappen der Klappvorrichtung durch eine Messeinheit ermittelt. Aufgrund von diversen Störeinflüssen können nämlich die Stellwinkel der einzelnen Klappen bezogen auf die eingestellte geschlossene Position, durchaus Abweichungen von 3° bis 4° aufweisen.in the Step S10 will therefore be the adjustment angle of the individual flaps of the Folding device determined by a measuring unit. Owing to various disturbing influences can namely the Adjustment angle of the individual flaps related to the set closed Position, quite different from 3 ° to 4 °.

Aus den im Schritt S10 ermittelten Stellwinkelwerten der Klappen wird im Schritt S30 ein gemittelter Stellwinkel berechnet. Im Schritt S40 wird der Stellwinkel der Klappvorrichtung mittels eines Aktors um einen vorgebbaren Wert mindestens einmal erhöht und/oder erniedrigt und dabei jeweils ein neuer gemittelter Stellwinkelwert über alle Klappen berechnet. Dabei wird als optimaler Stellwinkel der Klappvorrichtung für die geschlossene Position derjenige identifiziert, bei dem der berechnete gemittelte Stellwinkel minimal ist und/oder er sich innerhalb eines Grenzbereichs befindet.From the set angle values of the flaps determined in step S10, in step S30 a calculated telter setting angle. In step S40, the setting angle of the folding apparatus is increased and / or decreased at least once by a predefinable value by means of an actuator and in each case a new average setting angle value is calculated over all the valves. In this case, the optimum setting angle of the closed position folding device is identified as the one in which the calculated averaged setting angle is minimal and / or is within a limit range.

Im Schritt S50 wird der in Schritt S40 ermittelte optimale Stellwinkel in einer Sicherungseinheit abgespeichert.in the Step S50 becomes the optimum adjustment angle determined in step S40 stored in a fuse unit.
