Description
Vorrichtung zur Schließkrafterkennung eines elektrischen VerstellmotorsDevice for detecting the closing force of an electric adjusting motor
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung zurThe invention relates to a device for
Schließkrafterkennung eines elektrischen Verstellmotors der im Oberbegriff des Anspruchs 1 definierten Gattung.Closing force detection of an electric servomotor of the type defined in the preamble of claim 1.
Zur Schließkrafterkennung von elektrischen Verstellmotoren ist es bekannt, über die Stromerkennung bzw. die Drehzahlmessung in indirekter Weise Rückschlüsse auf die Schließkraft des Motors zu ziehen.For the closing force detection of electric actuators, it is known to draw conclusions about the closing force of the motor in an indirect manner via the current detection or the speed measurement.
So ist es bei der Stromerkennung allgemein bekannt, den Wechselanteil des Stromes ("Welligkeit") von Gleichstrommotoren als Maß für die Drehzahl des Motors zu erfassen, auszuwerten und auszunutzen. Dabei gibt es zwei Verfahren. Bei dem ersten Verfahren, dem sogenannten Nulldurchgangsverfahren, verläuft das Stromwelligkeitssignal im Mittel glatt und nach Eliminination des Gleichstromanteils werden die Nulldurchgänge erfaßt. Ein Beispiel dafür ist in der DE 35 27 906 AI beschrieben. Bei dem zweiten Verfahren, dem sogenannten ripple-count- Verfahren, verläuft das Signal wegen ungleicher Teilspulen auf Grund von Fertigungstoleranzen mit einer niederfrequenten Modulation, zusätzlich zur höherfrequenten Welligkeit. Es ergeben sich dabei lokale Minima und Maxima, bei denen Minima absolut höhere Werte als Maxima aufweisen können. Daher ist eine lokale Erfassung mittels eines aufwendigen, differenzierenden Verfahrens erforderlich.In current detection it is generally known to record, evaluate and utilize the alternating component of the current (“ripple”) of DC motors as a measure of the speed of the motor. There are two methods. In the first method, the so-called zero-crossing method, the current ripple signal runs smoothly on average, and after the DC component has been eliminated, the zero-crossings are detected. An example of this is described in DE 35 27 906 AI. In the second method, the so-called ripple count method, the signal runs with a low-frequency modulation due to unequal partial coils due to manufacturing tolerances, in addition to the higher-frequency ripple. This results in local minima and maxima, in which minima can have absolutely higher values than maxima. Local recording using a complex, differentiating method is therefore necessary.
Es ist auch bekannt, wie in einem Aufsatz "Unkonventionelle Drehzahlmessung und -regelung bei Gleichstrommotoren" von M. Birk, Elektronik 25/14.12.1984, S. 71, 72, beschrieben, die Drehzahl inkremental aus der Kommutierungswelligkeit des Ankerstroms zu bestimmen. Dazu wird eine an einem Meßwiderstand im Motorstromkreis abfallende Spannung über einen Kondensator kapazitiv ausgekoppelt und einem Filter zugeführt. Das Filter wird dabei adaptiv über den ganzen Drehzahlbereich mitgefahren, d. h. die Eckfrequenzen sind drehzahlabhängig veränderbar. Am Ausgang des Filters steht die aus der Kommutierungswelligkeit ausgefilterte Grundschwingung zur Verfügung. Die Frequenz dieses Signals ist proportional zur Drehzahl. Es ist hier ein erheblicher schaltungstechnischer Aufwand notwendig.It is also known, as described in an article "Unconventional speed measurement and control in DC motors" by M. Birk, Electronics 25 / 14.12.1984, p. 71, 72, to determine the speed incrementally from the commutation ripple of the armature current. For this purpose, a voltage drop across a measuring resistor in the motor circuit is capacitively coupled out via a capacitor and fed to a filter. The filter is driven adaptively over the entire speed range, i. H. the corner frequencies can be changed depending on the speed. The fundamental oscillation filtered out from the commutation ripple is available at the output of the filter. The frequency of this signal is proportional to the speed. A considerable amount of circuitry is required here.
In der älteren Patentanmeldung DE-44 22 083 der Anmelderin ist ein Verfahren und eine Anordnung angegeben, mit deren Hilfe oben genannte Probleme mit geringem Aufwand schaltungstechnischer und kostenmäßiger Art gelöst werden.The applicant's older patent application DE-44 22 083 specifies a method and an arrangement by means of which the above-mentioned problems can be solved with little effort in terms of circuitry and costs.
Eine andere Problemquelle liegt, wie die Praxis in diesem Zusammenhang gezeigt hat, darin, daß durch die übliche indirekte Messung der Schließkraft auch elektrische und magnetische Fehlerquellen Eingang in das Messergebnis finden. Dies trägt nicht zu einer zuverlässigen Messung und Erkennung der Schließkraft von elektrischen Verstellmotoren, insbesondere von Verstellmotoren mit Getrieben bei, die vorzugsweise in Kraftfahrzeugen Anwendung finden. Vorteile der ErfindungAnother problem source, as practice has shown in this connection, is that the usual indirect measurement of the closing force also means that electrical and magnetic sources of error are included in the measurement result. This does not contribute to reliable measurement and detection of the closing force of electric actuators, in particular actuators with gears, which are preferably used in motor vehicles. Advantages of the invention
Die erfindungsgemäße Vorrichtung zur Schließkrafterkennung eines elektrischen Verstellmotors mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil der direkten, unmittelbaren Messung bzw. Erkennung der Schließkraft, wobei in besonders vorteilhafter Weise alle Streuungen des elektromagnetischen Kreises des Motors und seiner Steuerung nicht in das Meßergebnis bzw. die Schließkrafterkennung Eingang finden. Daher ist bereits vom Prinzip her mit genaueren Ergebnissen zu rechnen als bei den bekannten indirekten Meßmethoden. Dies führt auch zu einer weniger aufwendigen und kostengünstigeren Gestaltung der Schließkrafterkennung.The device according to the invention for the detection of the closing force of an electric adjusting motor, with the characterizing features of claim 1, has the advantage of direct, direct measurement or detection of the closing force, in a particularly advantageous manner not scattering the electromagnetic circuit of the motor and its control into the measurement result or Find the closing force detection. Therefore, in principle, more precise results can be expected than with the known indirect measurement methods. This also leads to a less complex and less expensive design of the closing force detection.

Dies erlaubt die direkte Messung und Erkennung der Schließkraft.According to the invention, in the area of the motor shaft, in particular in the area of the shaft bearings, at least one force sensor is provided which responds to the reaction force of the motor shaft. This allows direct measurement and detection of the closing force.

Entsprechend einer vorteilhaften Weiterbildung der Erfindung ist mit zumindest einem der Kraftsensoren ein Positionssensor zur Positionserkennung der Motorwelle vorgesehen. In besonders zweckmäßiger Ausgestaltung der Erfindung ist der Positionssensor als intergrierter Hallsensor mit dem Kraftsensor kombiniert und auf der Motorwelle des Verstellmotors ein Ringmagnet zur Positionsdetektierung vorgesehen. ZeichnungAccording to an advantageous development of the invention, a position sensor for position detection of the motor shaft is provided with at least one of the force sensors. In a particularly expedient embodiment of the invention, the position sensor is combined as an integrated Hall sensor with the force sensor and a ring magnet for position detection is provided on the motor shaft of the adjustment motor. drawing

Der Antrieb erfolgt über eine Motorwelle 3. In Verlängerung der antreibenden Motorwelle 3 ist am getriebeseitigen Anlauf 4 ein Kraftsensor 5 zwischen Motorwelle 3 und einem Gehäuseteil 6 ortsfest angebracht. Am gegenüberliegenden Ende der Motorwelle 3, stößt diese am topfseitigen Anlauf 7 an die feststehende Wandung 8 eines Polgehäuses, das nur andeutungsweise dargestellt ist. Dieses Polgehäuse ist bevorzugt in Topfform gestaltet. Innerhalb desIn Fig. 1 an embodiment of the invention is shown schematically. The electric adjusting motor 1 drives a worm wheel 2 of an otherwise not shown gear. The drive takes place via a motor shaft 3. As an extension of the driving motor shaft 3, a force sensor 5 is fixed in place on the transmission-side start 4 between the motor shaft 3 and a housing part 6. At the opposite end of the motor shaft 3, this abuts on the cup-side run-up 7 against the fixed wall 8 of a pole housing, which is only indicated. This pole housing is preferably designed in a pot shape. Within the
Polgehäuses ist ein Ankerpaket 10 auf der Motorwelle 3 zu deren Antrieb vorgesehen.A pole assembly 10 is provided on the motor shaft 3 for driving the pole housing.
Die Motorwelle 3 ist im Bereich der beiden Enden, also im Bereich des getriebeseitigen Anlaufs 4 und des topfseiteigen Anlaufs 7 mittels zweier Wellenlager 11, die als Radiallager ausgebildet sein können, gelagert. Zwischen Ankerpaket 10 und dem Bereich des Schneckengewindes 12 auf der Motorwelle 3 kann ein weiteres Lager 13 vorgesehen sein, gegebenenfalls auch ein Positionssensor für die Erkennung der Rotationsstellung der Motorwelle 3. Des weiteren könnte auch ein zweiter Kraftsensor vorgesehen sein, wenn dies erforderlich und zweckmäßig erscheint, und zwar vorzugsweise am anderen Ende der Motorwelle 3, nämlich im topfseitigen Anlauf 7, also etwa spiegelbildlich zu der Anordnung des Kraftsensors 5 am getriebeseitigen Anlauf 4. Ausgestaltungsmäßig ist es auch möglich, den oder die Kraftsensoren 5 mit den jeweiligen Wellenlagern 11 zu kombinieren, wenn eindeutig feststeht, daß die Wellenlager die jeweiligen Reaktionskräfte der antreibenden Motorwelle 3 aufnehmen.The motor shaft 3 is supported in the region of the two ends, that is to say in the region of the start 4 on the transmission side and the start 7 on the cup side, by means of two shaft bearings 11, which can be designed as radial bearings. A further bearing 13 can be provided between the armature package 10 and the area of the worm thread 12 on the motor shaft 3, optionally also a position sensor for detecting the rotational position of the motor shaft 3. Furthermore, a second force sensor could also be provided if this appears necessary and expedient , in fact preferably at the other end of the motor shaft 3, namely in the cup-side run-up 7, that is to say approximately mirror image of the arrangement of the force sensor 5 on the gear-side start-up 4. In terms of design, it is also possible to combine the or the force sensors 5 with the respective shaft bearings 11 if it is clearly established that the shaft bearings absorb the respective reaction forces of the driving motor shaft 3.
Im dargestellten Ausführungsbeispiel ist die Motorwelle 3 mit dem Schneckengewinde 12 ausgestattet. Mit diesem wird das Schneckenrad 2 des Getriebes angetrieben. Dargestellt ist vom Getriebe noch die Abtriebswelle 13, auf welcher das Schneckenrad 2 montiert ist. Von diesem Getriebe können beispielsweise Fenster, Schiebedächer, Sitze oder Sitzteile in Kraftfahrzeugen verstellt werden.In the illustrated embodiment, the motor shaft 3 is equipped with the worm thread 12. The worm wheel 2 of the transmission is driven with this. The output shaft 13, on which the worm wheel 2 is mounted, is also shown of the transmission. Windows, sunroofs, seats or seat parts in motor vehicles can be adjusted by this transmission.
Bei Drehung der antreibenden Motorwelle 3 im Linkslauf LL, wird diese durch die zugehörige Reaktionskraft in Richtung auf den getriebeseitigen Anlauf 4 verschoben, wie dies durch die Spitze LL des Doppelpfeils 14 dargestellt ist. Bei axialer Verschiebung der Motorwelle 3 in diese Richtung wird der Kraftsensor 5 zusammengedrückt. Die entsprechende Drehbewgung des Schneckenrads 2 ist durch die Spitze LL am Doppelpfeil 15 dargestellt. Bei Drehung der antreibenden Motorwelle 3 im Rechslauf RL wird diese durch die zugehörige Reaktionskraft in Richtung auf den topfseitigen Anlauf 7 verschoben, wie dies durch die Spitze RL des Doppelpfeils 14 dargestellt ist. Die entsprechende Drehbewegung des Schneckenrads 2 ist durch die Sptze RL des Doppelpfeils 15 dargestellt. Bei axialer Verschiebung derWhen the driving motor shaft 3 rotates in the counterclockwise rotation LL, it is shifted by the associated reaction force in the direction of the gearbox-side start 4, as is shown by the tip LL of the double arrow 14. When the motor shaft 3 is axially displaced in this direction, the force sensor 5 is compressed. The corresponding rotary movement of the worm wheel 2 is represented by the point LL on the double arrow 15. When the driving motor shaft 3 rotates in the clockwise rotation RL, it is displaced by the associated reaction force in the direction of the cup-side start 7, as is shown by the tip RL of the double arrow 14. The corresponding rotary movement of the worm wheel 2 is represented by the point RL of the double arrow 15. With axial displacement of the
Motorwelle 3 in diese Richtung wird der Kraftsensor 5 entlastet.Motor shaft 3 is relieved of load in this direction.
Die Erfindung ermöglicht so auf einfache Weise die direkte Messung und Erkennung der Schließkraft des Verstellmotors 1. Eventuelle Störungen, Fehler und Streuungen im elektrischen und/oder elektromagnetischen Kreis des Motors bzw. seiner Steuerung, ist damit eliminiert und braucht dementsprechend nicht berücksichtigt zu werden.The invention thus enables the direct measurement and detection of the closing force of the adjusting motor 1 in a simple manner. Any faults, errors and scatter in the electrical and / or electromagnetic circuit of the motor or its Control, is thus eliminated and therefore need not be taken into account.
