Description

Stellorgane werden insbesondere in Fahrzeugen, wie Kraftfahrzeugen, Flugzeugen, Schiffen usw. verwendetet, um Klappen, Drosselklappen usw. verstellen zu können.Actuators are used in particular in vehicles such as motor vehicles, aircraft, ships, etc., in order to adjust flaps, throttle valves, etc.

Eine Steuereinrichtung für ein derartiges Stellorgan beschreibt die unveröffentlichte DE 101 00 966.6 . Die Steuereinrichtung umfaßt dabei einen Diametralmagneten und wenigstens einen Hall-Schalter. Der Magnet ist mit wenigstens einem Stellorgan verbunden und diametral oder mehrpolig segmentiert. Durch diesen Magneten wird bei Verstellung des Stellorgans und damit der Änderung seiner Lage zum Hall-Schalter über diesen ein Abschaltsignal für den Motor erzeugt. Dabei wird davon ausgegangen, daß die Segmentierung ein Maß der Winkelstellung insbesondere der Endlagen des Stellorgans sind.A control device for such an actuator describes the unpublished DE 101 00 966.6 , The control device comprises a diametrical magnet and at least one Hall switch. The magnet is connected to at least one actuator and segmented diametrically or multipolar. By this magnet, a shutdown signal for the motor is generated by adjusting the actuator and thus the change of its position to the Hall switch on this. It is assumed that the segmentation is a measure of the angular position, in particular the end positions of the actuator.

In der gleichfalls unveröffentlichten DE 101 23 605.0 ist ein Rundmagnet offenbart, der als dünnwandig Ringmagnet bzw. Teilringmagnet ausgeführt ist. Dieser weist eine lineare Feldabwicklung auf.In the likewise unpublished DE 101 23 605.0 is disclosed a circular magnet, which is designed as a thin-walled ring magnet or partial ring magnet. This has a linear field handling.

Aus der DE 37 26 885 A1 ist ein Verfahren und eine Anordnung zum Ermitteln der Stellweg-Endlagen eines Stellgliedes bekannt, wobei das Stellglied in eine bestimmte Richtung verstellt wird, bis eine Steuereinheit Stillstand feststellt.From the DE 37 26 885 A1 For example, a method and an arrangement for determining the travel end positions of an actuator is known, wherein the actuator is adjusted in a certain direction until a control unit detects a standstill.

Die Aufgabe der Erfindung liegt darin, eine weitere effektive Steuereinrichtung für einen Motor zur Verstellung eines Stellorgans aufzuzeigen.The object of the invention is to show a further effective control device for a motor for adjusting an actuator.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1.The problem is solved by the features of claim 1.

Der Erfindung liegt die Idee zugrunde, bei Erreichen einer einzustellenden Position eines zu verstellenden Stellorgans ein Signal zu erzeugen, mit welchem die nachfolgende bzw. nächste Laufrichtung des Motors voreingestellt wird, wobei sich diese nicht unbedingt ändern muß. Dazu kann beispielsweise ein bereits zum Abschalten des Motors erzeugtes Signal herangezogen werden, das von einem Hall-Schalter bereitgestellt wird, der mit einem Magneten am Stellorgan zusammenwirkt. Dieses Signal wird dann in einem Logikschaltkreis mit einem zweiten, einem Stellsignal verglichen, das je nach Definition (Software) zur Richtungsänderung des Motors entweder gleich oder unterschiedlich zum Hall-Schalter-Signal ist. Anhand der Auswertung wird dann der Motor so angesteuert, daß dieser bleibend oder sich ändernd in einen Rechts- oder in einen Linkslauf gedreht wird.
Der Logikschaltkreis arbeitet mit zwei unterschiedlichen Signalpegeln für die Laufrichtungen, einem low (0) und high (1) Signal.The invention is based on the idea, upon reaching a position to be adjusted of an adjusting member to be adjusted to generate a signal with which the subsequent or next direction of the motor is preset, which does not necessarily have to change. For this purpose, for example, a signal already generated for switching off the motor can be used, which is provided by a Hall switch, which cooperates with a magnet on the actuator. This signal is then compared in a logic circuit with a second, a control signal, which is either the same or different than the Hall-switch signal depending on the definition (software) for changing the direction of the motor. Based on the evaluation of the engine is then controlled so that this is permanent or changing in a clockwise or counterclockwise rotation.
The logic circuit operates with two different signal levels for the directions of travel, a low (0) and high (1) signal.

Zur Betätigung des Hall-Schalters ist ein segmentierter Diametralmagnet am Stellorgan vorgesehen, wobei bei Polungsumkehrung zwischen N (Nord) und S (Süd) am Hall-Schalter ein Signal erzeugt wird.To actuate the Hall switch, a segmented diametrical magnet is provided on the actuator, with a polarity reversal between N (north) and S (south) at the Hall switch, a signal is generated.

Eine weitere Variante ergibt sich bei der Nutzung eines Ring- bzw. Teilringmagneten nach der DE 101 23 605.0 . Der Hall-Schalter reagiert dann nicht bei der Polungsumkehr, sondern bei Erreichen eines vorgegebenen Spannungswertes, der vorzugsweise in den Hall-Schalter einprogrammierbar und durch die lineare Feldabwicklung eindeutig zugeordnet werden kann, wozu in Weiterführung der Erfindung ein programmierbarer Hall-Sensor Anwendung findet. Dadurch sind auch einzelne Winkelgrößen sowie unterschiedliche Endlage selbst frei programmierbar.Another variant results from the use of a ring or partial ring magnet after the DE 101 23 605.0 , The Hall switch then reacts not in the polarity reversal, but upon reaching a predetermined voltage value, which can be preferably programmed into the Hall switch and unambiguously assigned by the linear field unwinding, including in continuation of the invention, a programmable Hall sensor application. As a result, individual angular sizes and different end positions are freely programmable.

Mit einer derartigen Steuereinrichtung können unter anderem Einfachsteller, deren wichtigste Stellungen 0° und 90° sind und die dichtende Klappen verstellen, als auch Klappen mit unterschiedlichen Winkellagen oder Endlagen kleiner 90° angesteuert werden.With such a control device, among other things, single-plate, the most important positions are 0 ° and 90 ° and adjust the sealing flaps, as well as flaps are controlled with different angular positions or end positions less than 90 °.

Die Lösung ermöglicht eine verschleißfreie, berührungslose Klappensteuerung mit rechts/links Lauf und frei programmierbaren Winkel- (end-) -stellungen.The solution enables a wear-free, non-contact flap control with right / left run and freely programmable angle (end) settings.

Anhand eines Ausführungsbeispieles mit Zeichnung soll die Erfindung näher erläutert werden. Der Fachmann wird die Merkmale diesen Ausführungen entnehmen und diese zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Reference to an embodiment with drawing, the invention will be explained in more detail. The skilled person will refer to the features of these embodiments and expediently consider them individually and summarize meaningful further combinations.

In Fig. 1 ist eine Steuereinrichtung für ein hier nicht näher dargestelltes Stellorgan 20 als Schaltungsanordnung vereinfacht dargestellt. Mit 1 ist ein Magnet gekennzeichnet, hier ein segmentierter Rundmagnet 10, dem ein Hall-Schalter 2 zugeordnet ist. Der Rundmagnet 10 ist hier vierpolig und symetrisch ausgeführt, wobei die verschiedenen Polungsübergänge N/S bzw. S/N verschiedene Schaltpunkte am Hall-Schalter 2 definieren. Der Hall-Schalter 2 ist vorzugsweise programmierbar.
Ein Ausgang des Hall-Schalters 2 ist auf einen Eingang E2 eines Logikschaltkreises 3 geführt, dessen anderer Eingang E1 von einem separaten Steuergerät ( nicht näher dargestellt) mit Signalen beaufschlagt wird. Der Logikschaltkreis 3 ist ausgangsseitig auf eine vereinfacht dargestellte Brückenendschaltung 4 geführt, von der ein Motor 5 seine Ansteuersignale erhält.
Der Logikschaltkreis 3 wirkt als Verbindungsglied , d.h. als Vergleicher zwischen den Signalen des separaten Steuergerätes und den Signalen des Hall-Schalter 2 als Auswerteeinrichtung für das Schalten des Motors 5.
Mit Anliegen eines Stellsignals UST vom Steuergerät Logikschaltkreis 3 schaltet diese durch, wobei zu diesem Zeitpunkt vom Hall-Schalter 2 kein definiertes Signal UH geliefert wird. Mit Durchschaltung wird der Motor 5 angesteuert, wobei der Motor 5 seinerseits durch Verstellung des mit dem Rundmagnet 10 verbunden Stellorgans 20 die Lage des Segmentmagneten 10 zum Hall-Schalter 2 verstellt. Dabei verändert sich die Polungslage von beispielsweise N/S auf S/N zum Hall-Schalter 2. Dies bewirkt, daß der Hall-Schalter 2 bei der Umpolungsphase schaltet und ein entsprechendes Signal UH an den Logikschaltkreis 3 gelangt, wodurch der Motor 5 abgeschaltet wird.In Fig. 1 is a control device for a not shown here actuator 20 shown simplified as a circuit arrangement. 1 denotes a magnet, here a segmented round magnet 10 to which a Hall switch 2 is assigned. The round magnet 10 is embodied in this case as four-pole and symmetrical, wherein the different polarity transitions N / S or S / N define different switching points on the Hall switch 2. The Hall switch 2 is preferably programmable.
An output of the Hall switch 2 is fed to an input E2 of a logic circuit 3, the other input E1 is acted upon by a separate control device (not shown in detail) with signals. The logic circuit 3 is guided on the output side to a simplified illustrated bridge end circuit 4, from which a motor 5 receives its drive signals.
The logic circuit 3 acts as a link, ie as a comparator between the signals of the separate control unit and the signals of the Hall switch 2 as an evaluation device for the switching of the motor fifth
With concern of a control signal U ST from the control unit logic circuit 3, this turns on, at which time by the Hall switch 2 no defined signal U H is delivered. By switching the motor 5 is driven, the motor 5 in turn adjusts the position of the segment magnet 10 to the Hall switch 2 by adjusting the connected to the rotary magnet 10 actuator 20. In this case, the polarity changes from, for example, N / S to S / N to the Hall switch 2. This causes the Hall switch 2 switches at the Umpolungsphase and a corresponding signal U H reaches the logic circuit 3, whereby the motor 5 is turned off becomes.

Gleichzeitig wird über den Vergleich dieses Signals UH mit dem Stellsignal UST im Logikschaltkreis 3 festgestellt, welche Laufrichtung einzulegen ist, so daß die neue Laufrichtung rechts/links für den Motor 5 voreingestellt werden kann. Der Logikschaltkreis 3 vergleicht die Signalpegel der beiden Signale UH und UST , die je nach Software für eine Umschaltung einen gleichen oder einen unterschiedlichen Pegel aufweisen müssen. Der Motor 5 wird dann auf diese Umschaltung vorbereitet oder behält die alte Laufrichtung bei, was durch entsprechende Ausgangssignale der Brückenendschaltung 6 definiert wird.At the same time it is determined by comparing this signal U H with the control signal U ST in the logic circuit 3, which direction is to be inserted, so that the new direction right / left for the motor 5 can be preset. The logic circuit 3 compares the signal levels of the two signals U H and U ST , which must have the same or a different level depending on the software for a changeover. The motor 5 is then prepared for this switching or retains the old running direction, which is defined by corresponding output signals of the bridge-end circuit 6.

Bei Anliegen eines neuen umgekehrten Stellsignals UST vom Steuergerät wird nunmehr der Motor 5 in eine neue Laufrichtung bewegt. Dabei wiederholt sich diese Prozedur, wobei der Hall-Schalter 2 erneut schaltet und dieser ein neues Signal UH an den Logikschaltkreis 3 gibt, der Motor 5 abgeschaltet und dieser auf seine Laufrichtung vorbereitet wird.If a new reversed actuating signal U ST is applied by the control unit, the motor 5 is now moved in a new running direction. In this case, this procedure is repeated, the Hall switch 2 switches again and this gives a new signal U H to the logic circuit 3, the motor 5 is switched off and this is prepared for its direction.

Insbesondere bei einem Neustart entfällt in vorteilhafter Art und Weise eine Abfrage des Schaltzustandes des Hall-Schalter 2, eine Abfrage der aktuellen Stellung des Stellorgans 20 sowie des Motors 5.In particular, when restarting omitted in an advantageous manner an inquiry of the switching state of the Hall switch 2, a query of the current position of the actuator 20 and the motor fifth

In einer besonderen Variante, wie in Fig.1a dargestellt, wird anstelle des Segmentmagneten 10 ein dünnwandiger diametraler Ringmagnet 11 verwendet, dessen Feldabwicklung linear ist. Der hier verwendete Hall-Schalter 2, der gleichfalls programmierbar ist, reagiert dann nicht auf eine Polungsumkehr, sondern auf das Erreichen eines vorgegebenen Spannungswertes UR , der in den Hall-Schalter 2 einprogrammiert worden ist. Durch die Linearität der Feldabwicklung ist bei der Programmierung dieser Größe ein bestimmter Spannungswert UR zugeordnet.In a special variant, as in 1a shown, instead of the segment magnet 10, a thin-walled diametral ring magnet 11 is used, the Feldabwicklung is linear. The Hall switch 2 used here, which is also programmable, then does not respond to a polarity reversal, but to the achievement of a predetermined voltage value U R , which has been programmed into the Hall switch 2. Due to the linearity of the field development, a specific voltage value U R is assigned during the programming of this variable.

Bei einem Stellorgan 20, beispielsweise einer Drosselklappe, die bekanntlich zwei Zustände einnimmt, entweder "Voll-Auf" oder "Voll-Zu", erfolgt das Umschalten in eine andere Laufrichtung, wenn die Klappe ihre Endlagen 0° oder 90° erreicht hat.In an actuator 20, for example, a throttle valve, which is known to occupy two states, either "full-open" or "full-closed", switching to another direction occurs when the flap has reached its end positions 0 ° or 90 °.

Bei einem Stellorgan 20, das in kleineren Winkelpositionen stufenmäßig einzustellen ist, werden diese vorzugsweise in den Hall-Schalter 2 einprogrammiert. Eine Laufrichtungumschaltung erfolgt dabei je nach Programmierung. Vorteilhaft für dieses Stellorgan 20 ist dann die Verwendung des Diametralringmagneten 11, wobei auch ein fein segmentierter Magnet 10 zum Einsatz kommen kann.
Mit dieser bevorzugten Ausführung sind auch Stellorgane 20 mit Endlagen kleiner als 90° zu versehen, da diese Endlagen in den Hall-Schalter 2 einprogrammiert werden können.In an actuator 20, which is to be set stepwise in smaller angular positions, these are preferably programmed into the Hall switch 2. A direction change takes place depending on the programming. Advantageous for this Actuator 20 is then the use of the diametrical ring magnet 11, whereby a finely segmented magnet 10 can be used.
With this preferred embodiment, actuators 20 are also provided with end positions smaller than 90 °, since these end positions can be programmed into the Hall switch 2.

Der Vollständigkeit halber ist in Fig. 2 ein Stellorgan 20 nach dem Stand der Technik aufgezeigt, das mit dem Magneten 1 (10, 11) funktional verbunden ist.
Es kann als Magnet auch ein sektorenförmig am Umfang oder sektorenförmig auf der Fläche unterschiedlich gepolter Stabmagnet (nicht näher dargestellt) verwendet werden, wobei die rotierende Bewegung des Stellorgans in eine lineare Bewegung des Magneten 1 gegenüber dem Hall-Schalter 2 umgewandelt wird, was sich in einer Hin- und Herbewegung des Magneten 1 widerspiegelt.For completeness is in Fig. 2 an actuator 20 according to the prior art shown, which is operatively connected to the magnet 1 (10, 11).
It can be used as a magnet also a sector-shaped on the circumference or sector-shaped on the surface differently polarized bar magnet (not shown), wherein the rotating movement of the actuator is converted into a linear movement of the magnet 1 relative to the Hall switch 2, resulting in a reciprocating motion of the magnet 1 reflects.

Bei anderen Winkelstellungen, beispielsweise 0° und 180°, kann auch ein einfacher Diametralmagnet als Magnet 1 angewendet werden (nicht näher dargestellt).In other angular positions, for example 0 ° and 180 °, a simple diametrical magnet can be used as a magnet 1 (not shown in detail).
