Description
Die vorliegende Erfindung geht von einer entsprechend dem Oberbegriff des Hauptanspruches konzipierten elektrischen Schaltungsanordnung aus.The present invention is based on a corresponding to the preamble of Main claim designed electrical circuitry.
Derartige Schaltungsanordnungen sind dafür vorgesehen, um einen bestimmten Funktionszustand eines zwei verschiedene Funktionszustände aufweisenden elektrischen Systems dauerhaft zu erhalten. Dies ist z. B. dadurch möglich, daß dem System zur Initiierung der beiden Funktionszustände eine Leistungs-Schaltvorrichtung direkt zugeordnet wird, die zur Realisierung eines jeden der beiden Funktionszustände jeweils eine von einer Ausgangsstellung aus zu erreichende, rastend ausgeführte Schaltstellung aufweist.Such circuit arrangements are intended to a certain functional state of one of two different functional states having electrical system permanently. This is e.g. B. thereby possible that the system for initiating the two Functional states a power switching device is directly assigned, one to implement each of the two functional states To be reached from a starting position, executed in a latching manner Has switching position.
Im Zuge der Weiterentwicklung sind dann die die volle Leistung übertragenden und somit auch dieselbe unterbrechenden Schaltvorrichtungen durch tastend zu betätigende - nur Steuerströme führende - Schaltvorrichtungen, wie z.B. sogenannte Silikonschaltmatten, ersetzt worden, denen dann beispielsweise bistabile Leistungs-Schaltrelais zugeordnet werden. In the course of further development, the full power is transferred and thus also the same interrupting switching devices by groping Switching devices to be operated - only carrying control currents, e.g. so-called silicone safety mats, which were then replaced, for example bistable power switching relays can be assigned.
Solche Ausführungsformen bedingen aber einen recht erheblichen Aufwand sowohl hinsichtlich Material als auch bzgl. Platzbedarf.However, such embodiments require a considerable amount of effort both in terms of material and space requirements.
Weiterhin ist es bekannt, neben diesen elektromechanischen Lösungen eine elektronische Speicherung des jeweiligen Funktionszustandes vorzunehmen. Hierzu bedient man sich der schon lange bekannten, für die Speicherung eines digitalen Zustandes bestimmten bistabilen Kippstufe ( Flip/Flop ), die in unterschiedlichen Technologien - wie z.B. CMOS - realisiert werden kann. Allen so aufgebauten elektronischen Funktionsspeicherungen ist die Eigenschaft gemeinsam, daß der gespeicherte Zustand verloren geht, sobald die Versorgungsspannung der Schaltungsanordnung nicht mehr zur Verfügung steht. Das Vorhalten einer Hilfsenergie in Form einer Batterie, eines Akkumulators oder eines hochkapazitiven Kondensators ist wiederum mit erhöhtem Aufwand verbunden und nur bedingt langzeitstabil.Furthermore, it is known to have one besides these electromechanical solutions carry out electronic storage of the respective functional state. To do this, use the long-known one for storage of a digital state determined bistable flip-flop, which in different technologies - such as CMOS - can be realized. All of the electronic functional storages constructed in this way are Common feature that the saved state is lost as soon as the supply voltage of the circuit arrangement is no longer available Available. The provision of auxiliary energy in the form of a battery, an accumulator or a high-capacitance capacitor associated with increased effort and only partially stable over the long term.
Außerdem ist es z.B. durch die US-PS 4 388 704 bekannt, eine bistabile
Kippstufe ( Flip/Flop ) mit einer Einrichtung zu versehen, durch die der aktuelle
digitale Zustand der Kippstufe auch bei einer Unterbrechung der
Versorgungsspannung erhalten bleibt.
Eine solche Ausführungsform ist aber nicht ohne weiteres für in
Kraftfahrzeugen befindliche, über tastend zu betätigende Schaltvorrichtungen
zu beeinflussende elektrische Systeme geeignet.In addition, it is known, for example from US Pat. No. 4,388,704, to provide a bistable flip-flop with a device by means of which the current digital state of the flip-flop is retained even when the supply voltage is interrupted.
Such an embodiment is not, however, readily suitable for electrical systems located in motor vehicles and to be influenced by switching devices which can be actuated by touch.
Ferner ist es durch das RELAIS LEXIKON, 2.Auflage, Dr. Alfred Hüthig
Verlag, Heidelberg 1985, Seiten 62 und 226-242 bekannt, Schaltbausteine mit
integrierten als Steuerstufe anzusehenden Schaltkreisen zu kombinieren, so
daß auf einfache Weise eine Vielzahl von Schaltaufgaben im Zusammenhang
mit einer Leistungsschaltstufe realisierbar ist.
Dazu gehört auch eine mit einem herkömmlichen Flip/Flop versehene
Schaltungsanordnung, die durch impulsförmige Signale beeinflußbar ist, wobei
die impulsförmigen Signale natürlich auch von Tastschaltern hervorgerufen
sein können.Furthermore, it is through the RELAY LEXICON, 2nd edition, Dr. Alfred Hüthig Verlag, Heidelberg 1985, pages 62 and 226-242 known to combine switching modules with integrated circuits to be regarded as a control stage, so that a large number of switching tasks in connection with a power switching stage can be implemented in a simple manner.
This also includes a circuit arrangement provided with a conventional flip / flop, which can be influenced by pulse-shaped signals, wherein the pulse-shaped signals can of course also be caused by key switches.
Des Weiteren sind in dem Buch von Tietze, Schenk u.a., Halbleiter-Schaltungstechnik, Springer Verlag 1999 Seiten 751-752 elektrisch löschbare Festwertspeicher, d.h. sogenannte EEPROM's vom Grundsatz her beschrieben.Furthermore, in the book by Tietze, Schenk and others, semiconductor circuit technology, Springer Verlag 1999 pages 751-752 electrically erasable Read-only memory, i.e. so-called EEPROMs in principle described.
Darüber hinaus ist durch die DE 198 45 135 A1 eine mit mehreren zur Auslösung verschiedener Funktionen vorgesehenen Schaltvorrichtungen versehene elektrische Schaltungsanordnung bekannt geworden, wobei in eine dort vorhandene Steuerstufe ein als EEPROM ausgebildeter Speicherbaustein integriert ist, in dem eine Zuordnungstabelle abgelegt ist, die jeder einzelnen Schaltvorrichtung eine von der jeweiligen Schaltvorrichtung und/oder von der Steuerstufe zu beeinflussende Funktion aus einer Anzahl von Funktionen zuordnet.In addition, DE 198 45 135 A1 is one with several Triggering of various functions provided switching devices provided electrical circuitry become known, being in a control stage there, a memory module designed as an EEPROM is integrated, in which an assignment table is stored, that of each one Switching device one of the respective switching device and / or of the Control level function to be influenced from a number of functions assigns.
Schließlich ist durch die JP 09 298020 A eine die Merkmale des Obergriffs des
Patentanspruches 1 aufweisende elektrische Schaltungsanordnung bekannt
geworden. Dabei ist das vorzugsweise einer Wasseraufbereitungsanlage
zugehörige elektrische System von mehreren Steuerstufen zu beeinflussen,
wobei jeder Steuerstufe eine ein tastend zu betätigendes Schaltelement
aufweisende Schaltvorrichtung zugeordnet ist, deren Schaltzustand von einem
in einem Schaltbaustein integrierten, aus EEPROM-Zellen gebildeten Flip/Flop
gespeichert ist.
Bei dieser Ausführungsform ist aber jede Steuerstufe mit einem
Mikrocomputer versehen und über zwei Signalausgänge sowie eine
zweiadrige Datenbusleitung mit dem elektrischen System verbunden, was
einen ganz beachtlichen Aufwand darstellt. Finally, JP 09 298020 A has disclosed an electrical circuit arrangement which has the features of the upper grip of
In this embodiment, however, each control stage is provided with a microcomputer and connected to the electrical system via two signal outputs and a two-wire data bus line, which represents a very considerable outlay.
Aus den zuvor genannten Veröffentlichungen ist aber auch in der Zusammenschau ihrer Gegebenheiten kein Hinweis darauf zu entnehmen, ein nicht flüchtiges Flip/Flop aus wenigen EEPROM-Zellen zu realisieren und so auszubilden, d.h., in die Steuerstufe derart zu integrieren, daß das zugehörige System allein über einen Signal-Ausgang der Steuerstufe und somit über lediglich eine elektrische Verbindungsleitung zu beeinflussen ist.From the publications mentioned above is also in the Looking at their circumstances, there is no evidence to suggest one to realize non-volatile flip / flop from a few EEPROM cells and such to train, i.e. to integrate into the control stage in such a way that the associated System alone via a signal output from the control stage and thus via only an electrical connection line is to be influenced.
Aufgrund dessen liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine für in Kraftfahrzeugen vorhandene elektrische Systeme geeignete elektrische Schaltungsanordnung mit elektronischer Funktionsspeicherung zu schaffen, bei der auch bei einer externen oder internen Störung - wie Stromausfall oder Leitungsunterbrechung - der vorher vorhandene Funktionszustand über einen nahezu beliebig langen Zeitraum erhalten bleibt.Because of this, the present invention is based on the object suitable for electrical systems present in motor vehicles To create circuitry with electronic function storage, in the event of an external or internal fault - such as a power failure or Line interruption - the previously existing functional status via a is retained for almost any length of time.
Erfindungsgemäß wird die Aufgabe durch die im kennzeichnenden Teil des
Hauptanspruches angegebenen Merkmale gelöst.
Vorteilhaft bei einem derartigen Aufbau einer elektrischen
Schaltungsanordnung ist, daß dieselbe mit relativ einfachen Mitteln realisiert
werden kann, wobei diese nur einen recht geringen Platzbedarf haben.According to the invention the object is achieved by the features specified in the characterizing part of the main claim.
An advantage of such a construction of an electrical circuit arrangement is that it can be implemented with relatively simple means, which only require a very small amount of space.

Wie aus der Zeichnung hervorgeht, sind an einem in einem Kraftfahrzeug vorhandenen, beispielsweise als Fenster- bzw. Schiebedach-Verstelleinrichtung ausgebildeten, an der Versorgungsspannung U des Kraftfahrzeug - Bordnetzes liegenden elektrischen System S vier gleich ausgeführte Steuerstufen ST über eine Anschlußleitung AL mit jeweils ihrem Ausgang A angeschlossen, die ebenfalls mit der Spannungsversorgung verbunden sind. Jeder Steuerstufe ist wiederum eine zwei voneinander getrennte, tastend zu betätigende Schaltelemente SV1, SV2 aufweisende Schaltvorrichtung SV zugeordnet, über die ein funktional zugehöriges, einen Teil des Systems bildendes System - Aggregat zwischen zwei Funktionszuständen umschaltbar - z.B. ein- und ausschaltbar - ist. Natürlich kann anstelle der beiden Schaltelemente dem Grundsatz nach auch nur ein Schaltelement eingesetzt werden, wobei dann durch wiederholte Betätigungen desselben die Umschaltung zwischen den zwei Funktionszuständen realisierbar ist. Um einen solchen einmal eingenommenen Funktionszustand dauerhaft zu gewährleisten, ist die Steuerstufe mit einem Schaltbaustein SB versehen, der aus einem durch Anwendung der EEPROM - Technik zu einem nicht flüchtigen Gebilde avancierten und zwar insbesondere aus drei EEPROM-Zellen gebildeten Flip/Flop F/F besteht.As can be seen from the drawing, are in a motor vehicle existing, for example as a window or sunroof adjustment trained, at the supply voltage U des Motor vehicle electrical system lying electrical system S four the same executed control stages ST via a connecting line AL each with their Output A connected, which is also connected to the power supply are connected. Each control level is in turn two from each other separate switching elements SV1, SV2 to be operated by touch Assigned switching device SV, via which a functionally associated one System forming part of the system - aggregate between two Function states switchable - e.g. can be switched on and off - is. Naturally can in principle only one instead of the two switching elements Switching element are used, then by repeated operations switching between the two functional states is feasible. About such a functional state once assumed The control stage with an SB switch module must be guaranteed permanently provided that can be converted from one to another using the EEPROM technology Non-volatile objects advanced, particularly from three EEPROM cells formed flip / flop F / F.
Dieser bistabile elektronische Schaltbaustein ist in bewährter Prozeßtechnik mit einem SO-8-Gehäuse versehen, von dem der Eingang Vdd über einen Begrenzungswiderstand BW derart an der Versorgungsspannung U liegt, daß im Überspannungsfall die umgesetzte Verlustleistung begrenzt werden kann. Diese Arbeitsspannung wird über interne Schaltmittel SM auf den internen Versorgungseingang Vc geführt, an dem ein zur kurzfristigen Stabilisierung der Arbeitsspannung vorgesehener Stützkondensator C1 einerseits angeschlossen ist, der andererseits sowohl mit dem Masseanschluß GND als auch direkt mit Masse verbunden ist. Der Ausgang OUT des Schaltbausteins ist dann auf den Anschluß A der Steuerstufe ST geführt. Die beiden Anschlüsse L1, L0, die allgemein als SET, RESET Eingänge bezeichnet werden, sind über in ihren Verbindungsleitungen VL1, VL2 befindliche Vorwiderstände VW1, VW2 und denselben zugeordnete Leuchtdioden LD1, LD2 gemeinsam am positiven Pol (+) der Spannungsversorgung angeschlossen, wobei von den im sichtbaren Wellenspektrum arbeitenden Leuchtdioden vorzugsweise die eine Leuchtdiode LD1 Lichtstrahlen im roten Wellenlängenbereich und die andere Leuchtdiode LD2 Lichtstrahlen im grünen Wellenlängenbereich emittiert.This bistable electronic switching module is in proven process technology with an SO-8 housing, from which the input Vdd via a Limiting resistor BW is connected to the supply voltage U in such a way that in the event of an overvoltage, the power loss that is implemented can be limited. This working voltage is transferred to the internal via internal switching means SM Supply input Vc led to one for short-term stabilization the working capacitor C1 provided on the one hand is connected, on the other hand both with the GND ground connection is also directly connected to ground. The output OUT of the switching module is then led to connection A of the control stage ST. The two Connections L1, L0, commonly referred to as SET, RESET inputs are located in their connecting lines VL1, VL2 Series resistors VW1, VW2 and the associated LEDs LD1, LD2 together on the positive pole (+) of the power supply connected, with those working in the visible wave spectrum Light-emitting diodes preferably the one light-emitting diode LD1 light rays in the red Wavelength range and the other light emitting diode LD2 light rays in the green Wavelength range emitted.
An den beiden Eingängen L1, L0 des Schaltbausteins SB bzw. an die
denselben zugeordneten Verbindungsleitungen VL1, VL2 ist dann die
Schaltvorrichtung SV mit den beiden tastend zu betätigenden
Schaltelementen SV1, SV2 angeschlossen. Damit wird erreicht, daß durch die
Betätigung des Schaltelementes SV1 am Ausgang A des Schaltbausteins SB
der Zustand "1" hervorgerufen wird, während bei Betätigung des
Schaltelementes SV2 am Ausgang A der Zustand "0" generiert wird.
Der jeweils eingenommene Zustand wird dann durch die zugehörige
Leuchtdiode kenntlich gemacht.The switching device SV with the two switching elements SV1, SV2 to be actuated by touching is then connected to the two inputs L1, L0 of the switching module SB or to the connecting lines VL1, VL2 assigned to the same. It is thereby achieved that the state "1" is caused by the actuation of the switching element SV1 at the output A of the switching module SB, while the state "0" is generated when the switching element SV2 is actuated at the output A.
The respective state assumed is then identified by the associated light-emitting diode.
Um den an dem Signal-Ausgang A vorhandenen und damit auch dem
zugeordneten Systemteil zugehörigen Funktionszustand bis zu einer durch
eine erneute Betätigung der Schaltvorrichtung SV erfolgenden Umschaltung
zu erhalten, ist - wie aus Fig. 3 hervorgeht - der insbesondere als ASIC
ausgeführte elektronische Schaltbaustein SB mit dem vorteilhafterweise aus
drei EEPROM-Zellen gebildeten, nicht flüchtigen Flip/Flop F/F versehen.
Diese drei EEPROM-Zellen werden über ein Ansteuerorgan AO durch eine mit
den Schaltelementen SV1, SV2 verbundene Steuertogik SL in jeweils den
einen ihrer beiden möglichen Zustände versetzt. Eine den drei EEPROM-Zellen
nachgeordnete Auswertstufe AS erfaßt dabei über eine
Prüfkomponente PK, ob alle Zellen übereinstimmend sich in demselben
Zustand befinden. Ist dies der Fall, so wird über die Steuerlogik SL der Signal-Ausgang
A durch entsprechende Beeinflussung eines zugeordneten
elektronischen Schaltgliedes SG auf das dafür festgelegte Signalpotential
gebracht.
Weiterhin ist den EEPROM-Zellen eine Wahrscheinlichkeitskomponente WK
zugeordnet, durch die eine Mehrheitsentscheidung getroffen wird. Diese ist für
den Fall relevant, wenn bei der Zustandsveränderung der EEPROM-Zellen
eine Störung aufgetreten ist, wobei dann als wahrscheinlich richtig der von der
Mehrzahl der Zellen d.h. von zwei Zellen eingenommene Zustand angesehen
wird. Die Wahrscheinlichkeitskomponente WK beeinflußt dabei direkt das dem
Signal-Ausgang A zugeordnete Schaltglied SG.In order to maintain the functional state present at the signal output A and thus also associated with the assigned system part until a changeover occurs by a renewed actuation of the switching device SV, the electronic switching component SB, which is designed in particular as an ASIC, is included the non-volatile flip / flop F / F, advantageously formed from three EEPROM cells. These three EEPROM cells are set in one of their two possible states via a control element AO by a control logic SL connected to the switching elements SV1, SV2. An evaluation stage AS downstream of the three EEPROM cells uses a test component PK to determine whether all the cells are in the same state. If this is the case, the control output SL brings the signal output A to the signal potential defined for this purpose by correspondingly influencing an assigned electronic switching element SG.
Furthermore, a probability component WK is assigned to the EEPROM cells, by means of which a majority decision is made. This is relevant in the event that a fault has occurred during the change in the state of the EEPROM cells, in which case the state assumed by the majority of the cells, ie by two cells, is then likely to be correct. The probability component WK directly influences the switching element SG assigned to the signal output A.
