Abstract

The proposed electric circuit to control the driving of a window pane of a motor vehicle is arranged so that the motor (M1 resp. M2) may be started by means of a service switch (S1 resp. S2) also after switching off the ignition (opening of the ignition switch ZS) and after the opening of a vehicle door (closure of the door switch TK) or alternatingly until the opening of a vehicle door or until the opening and the closing of a door. The circuit is arranged so that only a very low work current circulates both when the ignition is on and when a door is open, as long as the service switch is not actuated, in order to prevent the battery from being discharged when the vehicle door remains open for a long time.

Description

Die Erfindung bezieht sich auf eine Schaltungsanordnung für den Antrieb eines verschiebbaren Bauteils in einem Kraftfahrzeug, insbesondere eines Kraftfahrzeugfensters, mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a circuit arrangement for driving a displaceable component in a motor vehicle, in particular a motor vehicle window, with the features of the preamble of claim 1.

Bei den bekannten Schaltungsanordnungen dieser Art, siehe GB-A-1 163 389 die für die elektrische Betätigung eines Kraftfahrzeug-Fensters bestimmt sind, liegt die Relaiswicklung in einem Stromkreis, der bei eingeschalteter Zündung geschlossen ist. Dann kann das Fenster durch Betätigen des Betriebsschalters geöffnet oder geschlossen werden während bei ausgeschalteter Zündung ein Öffnen oder Schließen des Fensters nicht möglich ist. Bei der aus der GB-A-1 163 389 bekannten Schaltanordnung besteht auch die Möglichkeit, das oder die Fenster auch bei offener Türe zu betätigen, indem ein Türkontaktschalter vorgesehen wird, der bei geöffneter Tür den Stromkreis der Relaiswicklung schließt. Hiebei besteht jedoch die Gefahr, daß sich die Batterie durch die Stromaufnahme der Relaiswicklung über Nacht entlädt, wenn die Tür versehentlich nicht ganz geschlossen wurde. Außerdem würde die Relaisspule ständig von Strom durchflossen, solange die Zündung eingeschaltet ist, was eine oftmals unerwünschte Wärmeentwicklung und einen hohen Stromverbrauch zur Folge hätte. Schließlich fordern gesetzliche Bestimmungen in verschiedenen Staaten, daß nach dem Ausschalten der Zündung eine Betätigung des Fensters nach dem Öffnen der Fahrertür oder nach dem Öffnen und Wiederschließen der Fahrertür nicht mehr möglich ist.In the known circuit arrangements of this type, see GB-A-1 163 389, which are intended for the electrical actuation of a motor vehicle window, the relay winding lies in a circuit which is closed when the ignition is switched on. Then the window can be opened or closed by pressing the operating switch, while opening or closing the window is not possible when the ignition is switched off. In the switching arrangement known from GB-A-1 163 389 it is also possible to operate the window or windows even with the door open by providing a door contact switch which closes the circuit of the relay winding when the door is open. However, there is a risk that the battery will discharge overnight due to the current consumption of the relay winding if the door is accidentally not fully closed. In addition, current would flow through the relay coil as long as the ignition was switched on, which would often result in undesirable heat generation and high power consumption. Finally, legal regulations in various states require that after the ignition has been switched off, it is no longer possible to operate the window after opening the driver's door or after opening and closing the driver's door.

Der Erfindung liegt die Aufgabe zugrunde, eine Schaltungsanordnung zu schaffen, die einerseits ein Öffnen oder Schließen eines Kraftfahrzeugfensters oder eines anderen verschiebbaren Bauteils, beispielsweise eines Schiebedaches, bei offener Fahrzeugtür bzw. je nach den gesetzlichen Bestimmungen bis zum Öffnen der Fahrertür oder bei offener Fahrertür bis zum Wiederschließen derselben auch dann ermöglicht, wenn die Zündung ausgeschaltet ist, andererseits aber eine so geringe Ruhestromaufnahme hat, daß bei einem versehentlichen Offenbleiben der Tür ein Entladen der Batterie nicht eintreten kann und eine unerwünschte Wärmeentwicklung und ein hoher Energieverbrauch auch bei eingeschalteter Zündung vermieden wird.The invention has for its object to provide a circuit arrangement, on the one hand, opening or closing a motor vehicle window or another displaceable component, for example a sliding roof, with the vehicle door open or, depending on the legal provisions, until the driver's door is opened or the driver's door is open for reclosing the same even when the ignition is switched off, but on the other hand has such a low quiescent current consumption that if the door is accidentally left open, the battery cannot discharge and undesirable heat generation and high energy consumption are avoided even when the ignition is switched on.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Kennzeichens des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Bei der erfindungsgemäßen Schaltungsanordnung wird der Stromkreis der Relaiswicklung erst dann geschlossen, wenn entweder die Zündung eingeschaltet oder der Türkontakt betätigt ist und gleichzeitig der bzw. ein Betriebsschalter eingeschaltet ist. Ohne Betätigung des Betriebsschalters fließt nur ein Ruhestrom von weniger als 1 mA und bei der Verwendung von CMOS-Bausteinen ein solcher von wenigen A, so daß keine nennenswerte Wärmeentwicklung eintreten kann, der Stromverbrauch minimal und bei einer Schaltung mit geschlossenem Türkontakt bei offener Fahrzeugtür auch ein Entladen der Batterie ausgeschlossen ist.In the circuit arrangement according to the invention, the circuit of the relay winding is only closed when either the ignition is switched on or the door contact is actuated and at the same time the or an operating switch is switched on. Without actuation of the operating switch, only a quiescent current of less than 1 mA flows and, when using CMOS components, a quiescent current of a few A, so that no appreciable heat development can occur, the power consumption is minimal and also occurs with a circuit with closed door contact with the vehicle door open Discharging the battery is excluded.

Zweckmäßige Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Appropriate developments of the invention result from the subclaims.

Zwei Ausführungsbeispiele der erfindungsgemäßen Schaltungsanordnung sind in der Zeichnung dargestellt.Two exemplary embodiments of the circuit arrangement according to the invention are shown in the drawing.

In Fig. 1 sind mit M1 und M2 die Motoren von zwei Kraftfahrzeug-Fenstern bezeichnet, die für Rechts- und Linkslauf ausgerüstet sind und je nach Drehrichtung das zugeordnete Fenster öffnen oder schließen, wenn ein Betriebsschalter S1 bzw. S2 entsprechend betätigt wird. Die Schalter S1 und S2 sind der Einfachheit halber als einfache Unterbrecherschalter gezeichnet, obgleich in der Praxis wegen der Notwendigkeit, die Motoren umpolen zu müssen, Wechselschalter verwendet werden. Die Betriebsschalter S1 und S2 liegen in Reihe mit einem Relaiskontakt R, der mit dem Pluspol der Fahrzeugbatterie verbunden ist. Wenn der Relaiskontakt R geschlossen ist, so kann durch Betätigung des Schalters S1 der Motor M1 und durch Betätigung des Schalters S2 der Motor M2 eingeschaltet und das zugehörige Fenster entsprechend bewegt werden.In Fig. 1, M1 and M2 denote the motors of two motor vehicle windows which are equipped for clockwise and anti-clockwise rotation and, depending on the direction of rotation, open or close the associated window when an operating switch S1 or S2 is actuated accordingly. Switches S1 and S2 are drawn as simple break switches for simplicity, although changeover switches are used in practice due to the need to reverse the polarity of the motors. The operating switches S1 and S2 are in series with a relay contact R, which is connected to the positive pole of the vehicle battery. When the relay contact R is closed, the motor M1 can be switched on by actuating the switch S1 and the motor M2 can be switched on by actuating the switch S2 and the associated window can be moved accordingly.

Die Relaiswicklung RW ist einerseits an die Plusleitung 10 angeschlossen und andererseits über eine Leitung 12 mit einer Masseleitung 14 verbindbar, wenn bestimmte Bedingungen vorliegen, nämlich geschlossener Türkontaktschalter TK (d. h. offene Fahrzeugtür) oder geschlossener Zündschalter ZS und gleichzeitig mindestens ein geschlossener Betriebsschalter S1 oder S2. In der Leitung 12 ist ein Transistor T1 angeordnet, dessen Basis über eine Leitung 16 mit einem Widerstand 18 mit dem Ausgang eines ersten Komparators 20 verbunden ist. Der nicht invertierende Eingang dieses Komparators 20 ist über eine Diode 32 mit dem Ausgang eines zweiten Komparators 22 verbunden. Der invertierende Eingang des ersten Komparators 20 ist einerseits durch eine Leitung 24 und den Türkontaktschalter TK und andererseits über einen von dem Zündschalter ZS gesteuerten Transistor T2 mit Masse verbindbar. Bei geschlossenem Türkontaktschalter TK liegt der invertierende Eingang des ersten Komparators 20 direkt an Masse, während bei eingeschalteter Zündung die Basis des Transistors T2 Spannung erhält und den Transistor T2 durchschaltet und dadurch den invertierenden Eingang des ersten Komparators 20 mit der Masseleitung 24 verbindet. Der invertierende Eingang des ersten Komparators 20 ist ferner über einen Widerstand 26 mit der Plusleitung 10 verbunden. Der Widerstand 26 dient als Arbeitswiderstand für den Transistor T2 und verhindert einen Kurzschluß bei geschlossenem Türkontaktschalter TK.The relay winding RW is connected on the one hand to the positive line 10 and on the other hand can be connected via a line 12 to a ground line 14 if certain conditions exist, namely a closed door contact switch TK (i.e. open vehicle door) or a closed ignition switch ZS and at the same time at least one closed operating switch S1 or S2. A transistor T1 is arranged in line 12, the base of which is connected via a line 16 to a resistor 18 to the output of a first comparator 20. The non-inverting input of this comparator 20 is connected via a diode 32 to the output of a second comparator 22. The inverting input of the first comparator 20 can be connected to ground on the one hand via a line 24 and the door contact switch TK and on the other hand via a transistor T2 controlled by the ignition switch ZS. When the door contact switch TK is closed, the inverting input of the first comparator 20 is connected directly to ground, while when the ignition is switched on, the base of the transistor T2 receives voltage and turns on the transistor T2 and thereby connects the inverting input of the first comparator 20 to the ground line 24. The inverting input of the first comparator 20 is also connected to the positive line 10 via a resistor 26. The resistor 26 serves as a load resistor for the transistor T2 and prevents a short circuit when the door contact switch TK is closed.

Der invertierende Eingang des zweiten Komparators 22 ist über eine Leitung 28 mit der Plusleitung 10a zwischen dem Relaiskontakt R und den Betriebsschaltern S1 und S2 verbunden. Die Zweige 10 und 10a der Plusleitung sind ferner durch einen hochohmigen Widerstand 30 miteinander in Verbindung, der so ausgelegt ist, daß der Motor M1 oder M2 bei geschlossenem Betriebsschalter S1 oder S2 nicht läuft, aber der Komparator 22 mit der Plusleitung 10 verbunden wird. Der nicht invertierende Eingang des zweiten Komparators 22 ist über einen Widerstand 34 mit der Plusleitung 10 und über eine Diode 40 mit der Masseleitung 14 verbunden.The inverting input of the second compa rators 22 is connected via a line 28 to the positive line 10a between the relay contact R and the operating switches S1 and S2. The branches 10 and 10a of the positive line are also connected to one another by a high-resistance resistor 30, which is designed such that the motor M1 or M2 does not run when the operating switch S1 or S2 is closed, but the comparator 22 is connected to the positive line 10. The non-inverting input of the second comparator 22 is connected to the positive line 10 via a resistor 34 and to the ground line 14 via a diode 40.

Schließlich ist der nicht invertierende Eingang des ersten Komparators 20 durch ein RC-Glied, bestehend aus dem Kondensator 36 und dem Widerstand 38, mit der Masse-Leitung 14 verbunden. Die Diode 32 verhindert, daß sich der Kondensator 36 über den zweiten Komparator 22 entladen kann.Finally, the non-inverting input of the first comparator 20 is connected to the ground line 14 by an RC element consisting of the capacitor 36 and the resistor 38. The diode 32 prevents the capacitor 36 from being able to discharge via the second comparator 22.

Die Wirkungsweise der dargestellten Schaltung ist folgende :

  • Bei geschlossenem Türkontaktschalter TK und/ oder geschlossenem Zündschalter ZS wird zwar der invertierende Eingang des ersten Komparators 20 an Masse gelegt. Solange jedoch nicht einer der Betriebsschalter S1, S2 betätigt ist, fließt kein Strom zur Basis des Transistors T1, sodaß dieser gesperrt bleibt und die Relaiswicklung RW nicht mit Strom versorgt wird, der Relaiskontakt R also offen bleibt. Bei nicht geschlossenem Schalter S1 oder S2 liegt der invertierende Eingang des zweiten Komparators 22 über die Leitung 28 und den Widerstand 30 an der Plusleitung 10 an, während das Potential am nicht invertierenden Eingang aufgrund des Widerstands 34 und der Diode 40 niedriger ist (Referenzspannungsquelle). Der nicht invertierende Eingang des ersten Komparators 20 wird also nicht mit Spannung versorgt. Wenn einer der Betriebsschalter S1, S2 betätigt ist, so wird der invertierende Eingang des zweiten Komparators 22 über die Wicklung des betreffenden Motors M1 oder M2 mit Masse verbunden. Dadurch wird nun an den nicht invertierenden Eingang des ersten Komparators 20 Spannung angelegt, sodaß der Transistor T1 durchgeschaltet und die Relaiswicklung RW erregt wird. Dadurch wird der Relaiskontakt R geschlossen und der betreffende Motor M1 oder M2 mit Strom versorgt. Die Zeit vom Schließen des Schalters S1 oder S2 bis zum Anziehen des Relais wird dazu benutzt, den Kondensator 36 aufzuladen. Das RC-Glied 36, 38 hat eine Zeitkonstante, die der Zeit entspricht, die zum vollständigen Öffnen oder Schließen des Fensters nötig ist, z. B. 15 s. Das RC-Glied bewirkt, daß der erste Komparator 20 Spannung abgibt, wenn der Relaiskontakt R geschlossen ist. Ohne das RC-Glied würde bei geschlossenem Relaiskontakt R der erste Komparator 20 die Basis des Transistors T1 nicht mit Strom versorgen, da der zweite Komparator 22 keine Spannung abgibt. Wenn der Schalter S1 oder S2 geöffnet wird, bleibt der betreffende Motor stehen.
Sind beide Schalter TK und ZS offen, so wird bei einem Betätigen des Schalters S1 oder S2 der Transistor T1 nicht durchgeschaltet, da der invertierende Eingang des ersten Komparators 20 über den Widerstand 26 auf einem höheren positiven Potential liegt als der nicht invertierende Eingang.The circuit works as follows:
  • When the door contact switch TK and / or the ignition switch ZS are closed, the inverting input of the first comparator 20 is indeed connected to ground. However, as long as one of the operating switches S1, S2 is not actuated, no current flows to the base of the transistor T1, so that it remains blocked and the relay winding RW is not supplied with current, that is to say the relay contact R remains open. If the switch S1 or S2 is not closed, the inverting input of the second comparator 22 is connected to the positive line 10 via the line 28 and the resistor 30, while the potential at the non-inverting input is lower due to the resistor 34 and the diode 40 (reference voltage source). The non-inverting input of the first comparator 20 is therefore not supplied with voltage. If one of the operating switches S1, S2 is actuated, the inverting input of the second comparator 22 is connected to ground via the winding of the relevant motor M1 or M2. As a result, voltage is now applied to the non-inverting input of the first comparator 20, so that the transistor T1 is turned on and the relay winding RW is excited. This closes the relay contact R and supplies the relevant motor M1 or M2 with current. The time from closing switch S1 or S2 until the relay is energized is used to charge capacitor 36. The RC element 36, 38 has a time constant which corresponds to the time required for the window to be fully opened or closed, e.g. B. 15 s. The RC element causes the first comparator 20 to deliver voltage when the relay contact R is closed. Without the RC element, when the relay contact R is closed, the first comparator 20 would not supply the base of the transistor T1 with current, since the second comparator 22 does not supply any voltage. If switch S1 or S2 is opened, the motor in question stops.
If both switches TK and ZS are open, the transistor T1 is not turned on when the switch S1 or S2 is actuated, since the inverting input of the first comparator 20 is at a higher positive potential than the non-inverting input via the resistor 26.

Es ist ersichtlich, daß bei nicht betätigtem Betriebsschalter S1 oder S2 nur ein geringer Betriebsstrom in der Größenordnung von weniger als 1 mA fließt, auch wenn einer der Schalter TK oder ZS geschlossen ist.It can be seen that when the operating switch S1 or S2 is not actuated, only a small operating current of the order of less than 1 mA flows, even if one of the switches TK or ZS is closed.

Die in Fig. 2 dargestellte Schaltung unterscheidet sich von der Schaltung gemäß Fig. 1 im wesentlichen nur dadurch, daß die Basis des Transistors T2 durch einen Informationsspeicher M in Form eines Flip-Flop wahlweise mit der Spannungsquelle (+) oder mit Masse verbindbar ist. Das Flip-Flop wird beim Schließen des Zündschalters ZS gesetzt und damit die Basis des Transistors T2 mit der Spannungsquelle verbunden, sodaß die Motoren M, und M2 durch Betätigen der Betriebsschalter S, und S2 eingeschaltet werden können. Wird nun der Zündschalter ZS geöffnet, also die Zündung ausgeschaltet, so bleibt das Flip-Flop gesetzt und der Transistor T2 leitend, sodaß die Relaiswicklung RW in der vorstehend im Zusammenhang mit Fig. 1 beschriebenen Weise dann von Strom durchflossen wird, wenn einer der Betriebsschalter Sl, S2 betätigt wird. Wenn nun eine Fahrzeugtür geöffnet wird, so wird der Türkontaktschalter TK geschlossen, wodurch der Informationsspeicher M gelöscht und die Basis des Transistors T2 mit Masse verbunden wird. Damit ist der Transistor T2 gesperrt, was, wie ebenfalls vorher beschrieben, zur Folge hat, daß der Stromkreis der Relaiswicklung RW unterbrochen und der Relaiskontakt R geöffnet wird, sodaß keiner der Motoren Mi, M2 durch Betätigung des zugehörigen Betriebsschalters S, oder S2 eingeschaltet werden kann. Dies ist erst dann wieder möglich, wenn der Zündschalter ZS geschlossen wird, das erst dadurch das Flip-Flop wieder gesetzt wird. Wie bei der Schaltung gemäß Fig. 1 fließt auch bei geschlossenem Zündschalter ZS oder geschlosenem Türkontaktschalter TK nur ein geringer Betriebsstrom, solange keiner der Betriebsschalter betätigt wird.The circuit shown in FIG. 2 differs from the circuit shown in FIG. 1 essentially only in that the base of the transistor T 2 can be connected either to the voltage source (+) or to ground by means of an information memory M in the form of a flip-flop . The flip-flop is set when the ignition switch ZS is closed and thus the base of the transistor T 2 is connected to the voltage source, so that the motors M, and M 2 can be switched on by operating the operating switches S, and S 2 . If the ignition switch ZS is now opened, i.e. the ignition is switched off, the flip-flop remains set and the transistor T 2 is conductive, so that current flows through the relay winding RW in the manner described above in connection with FIG. 1 when one of the Operating switch S l , S 2 is operated. If a vehicle door is now opened, the door contact switch TK is closed, as a result of which the information memory M is erased and the base of the transistor T 2 is connected to ground. So that the transistor T 2 is blocked, which, as also described above, has the consequence that the circuit of the relay winding RW is interrupted and the relay contact R is opened, so that none of the motors M i , M 2 by actuating the associated operating switch S, or S 2 can be turned on. This is only possible again when the ignition switch ZS is closed, which only sets the flip-flop again. As in the circuit according to FIG. 1, only a small operating current flows even when the ignition switch ZS is closed or the door contact switch TK is closed, as long as none of the operating switches is actuated.

In verschiedenen Staaten besteht die Bestimmung, daß der Motor M, oder M2 durch Betätigen seines Betriebsschalters S, bzw. S2 eingeschaltet werden kann, solange eine Fahrzeugtür geöffnet ist, daß jedoch ein derartiges Einschalten dann nicht mehr möglich sein darf, wenn die betreffende Tür wieder geschlossen ist. Für diesen Fall ist der Informationsspeicher M so ausgebildet, daß er nach dem Setzen durch Schließen des Zündschalters ZS auch nach Öffnen des Zündschalters ZS und nach Öffnen der Tür, 'also Schließen des Türkontaktschalters TK, gesetzt bleibt und erst nach dem Wiederschließen der Tür durch Öffnen des Türkontaktschalters TK gelöscht wird, sodaß der Transistor T2 sperrt und damit der Stromkreis der Relaiswicklung RW durch den Transistor T, auch bei Betätigung eines Betriebsschalters S, oder S2 nicht mehr geschlossen werden kann. Dies ist vielmehr erst dann wieder möglich, wenn der Zündschalter ZS geschlossen ist.In various states there is a provision that the motor M, or M 2 can be switched on by actuating its operating switch S, or S 2 , as long as a vehicle door is open, but that such switching on may no longer be possible if the relevant one Door is closed again. In this case, the information memory M is designed so that it remains set after setting by closing the ignition switch ZS even after opening the ignition switch ZS and after opening the door, that is to say closing the door contact switch TK, and only after the door has been closed again by opening of the door contact switch TK is deleted, so that the transistor T 2 blocks and thus the circuit of the relay winding RW through the transistor T, even when an operating switch S, or S 2 is no longer activated can be closed. Rather, this is only possible again when the ignition switch ZS is closed.
