Description

Die Erfindung betrifft ein Verfahren zum Betrieb servobetätigter Schließeinrichtungen, insbesondere für Fenster, Türen, Schiebedächer od.dgl. von Kraftwagen, wobei in Zusammenarbeit mit einem Zeit- oder Wegmeßglied die Schließkraft während der Schließbewegung über eine definierte Zeit bzw. einem definierten Weg ständig erfaßt, integriert und/oder differenziert und gespeichert wird und bei einem zu hohen, schnellen Kraftanstieg über den zuvor gespeicherten Wert hinaus der Antrieb auf Null oder auf Rückwärtslauf geschaltet wird, nach Patent (Patentanmeldung P 27 27 518.9).The invention relates to a method for operating servo-operated locking devices, in particular for windows, doors, sliding roofs or the like. of motor vehicles, whereby the closing force during the closing movement over a defined time or a defined path is constantly detected, integrated and / or differentiated and stored in cooperation with a time or distance measuring element and in the event of an excessive, rapid increase in force above the previously stored value In addition, the drive is switched to zero or reverse, according to patent (patent application P 27 27 518.9).

Der vorliegenden Erfindung lag die Aufgabe zugrunde, einen Weg aufzuzeigen, um ein besonders einfaches Ermitteln des Kraftanstiegs ohne mechanischen Eingriff in die Schließeinrichtung zu ermöglichen.The present invention was based on the object of showing a way to enable a particularly simple determination of the force increase without mechanical intervention in the locking device.

Dies wird erfindungsgemäß dadurch erreicht, daß als Servoeinrichtung ein Elektromotor dient und der Kraftanstieg über den Stromanstieg ermittelt wird.This is achieved according to the invention in that an electric motor is used as the servo device and the increase in force is determined via the increase in current.

Ein solches Ermitteln des Stromanstiegs ist mittels elektronischer Bauteile auf einfachste Weise möglich.Such a determination of the increase in current is possible in the simplest way by means of electronic components.

Die Ermittlung des Kraftanstiegs über den Stromanstieg ist auch technisch völlig befriedigend, weil es sich gezeigt hat, daß Kraftanstieg und Stromanstieg genau gleich verlaufen.The determination of the increase in force via the increase in current is also completely satisfactory from a technical point of view, because it has been shown that increase in force and increase in current run exactly the same.

Der Gegenstand der Erfindung soll im folgenden anhand eines in Fig. 1 der Zeichnung dargestellten Blockschaltbildes erläutert werden. Die Fig. 2 und 3 der Zeichnung zeigen mögliche Schaltungen eines Integrators und eines Differentiators.The subject matter of the invention will be explained below with reference to a block diagram shown in FIG. 1 of the drawing. FIGS. 2 and 3 of the drawing show possible circuits of an integrator and a differentiator.

Einem Stromfühler 1 ist ein Verstärker 2 nachgeschaltet, der einen Integrator 3 oder einen Differentiator 3a beaufschlagt. Dieses elektronische Bauteil 3, als Integrator nach Fig. 2 oder als Differentiator nach Fig. 3 aufgebaut, läßt sich nach dem gewünschten Strom(Kraft)/Zeitintervall auslegen. Eine Auslegungsform kann sein, daß z.B. hohe Anlaufspitzen (Haftreibung) unterdrückt werden, die momentane Stromstärke (Schließkraft) über einen Zeitraum von jeweils 0,1 sec während des ganzen Fenster-Schließvorgangs erfaßt wird und bei einem sehr schnellen Stromanstieg (Kraftanstieg) ein Schaltsignal einem nachgeschalteten Schwellwertschalter 4 zugeleitet wird. Über eine Endstufe 5 wird ein nicht dargestellter Schalter angesteuert, der entweder die Stromzuführung zum Elektromotor abschaltet, oder diesen auf Rückwärtslauf und nach kurzer Zeit selbsttätig wieder auf Vorlauf umschaltet.A current sensor 1 is followed by an amplifier 2, which acts on an integrator 3 or a differentiator 3a. This electronic component 3, constructed as an integrator according to FIG. 2 or as a differentiator according to FIG. 3, can be designed according to the desired current (force) / time interval. One design form can be that, for example, high starting peaks (static friction) are suppressed, the current strength of the current (closing force) is recorded over a period of 0.1 seconds during the entire window closing process and a switching signal is issued in the event of a very rapid current increase (force increase) downstream threshold switch 4 is fed. A switch, not shown, is controlled via an output stage 5, which either switches off the power supply to the electric motor or switches it to reverse and after a short time automatically switches it back to forward.

Während des Einlaufens der Fensterscheibe in den oberen Fensterrahmenteil ist eine höhere Schließkraft und damit eine größere Stromstärke erforderlich. Sollte sich durch die konstruktive Gestaltung ergeben, daß erstere höher ist als die gewünschte Überschußkraft, so kann die strombegrenzende Elektronik durch einen Endschalter ausgeschaltet werden.While the window pane is running into the upper window frame part, a higher closing force and thus a higher current intensity is required. Should it result from the structural design that the former is higher than the desired excess force, the current-limiting electronics can be switched off by a limit switch.
