Abstract

Vehicle locking system which can be remote-controlled by a transmitter signal (I), having a transportable transmitter/key (S) and having a receiver (E) which is fitted in the vehicle and controls the locking of at least one lock (V) of at least one opening, for example the locking of the lock (V) of the vehicle door. The receiver (E) can have at least two states, namely a first state in which it (E) leaves the lock (V) concerned in the locked state, possibly also locks the previously unlocked lock (V), as well as a second state in which it (E), prompted by the transmitter signal (I), allows the opening concerned to be opened. In its second state, the receiver (E) allows the opening of the opening for a predetermined period of time, which is initiated by the transmitter signal (I), the receiver (E) changing automatically from its second state into its first state at the end of the period of time if the opening still has not opened by then. <IMAGE>

to be able to touch or actuate the contact when opening the opening in a particularly simple manner, which is very inconspicuous for outsiders.

Die Erfindung und Weiterbildungen derselben werden anhand des in der Figur gezeigten Schemas eines Ausführungsbeispieles der Erfindung weiter erläutert, welches der Übersichtlichkeit wegen möglichst einfach dargestellt wurde.The invention and further developments of the same are further explained on the basis of the diagram of an embodiment of the invention shown in the figure, which has been shown as simply as possible for the sake of clarity.

Diese Figur zeigt also ein Beispiel für das erfindungsgemäße, durch ein Sendersignal I fernsteuerbares Kfz-Schließsystem. Das Kfz enthält Schlösser V, welche mittels des Senders S entriegelt werden können, um z.B. den Zutritt in das Kfz und/oder das Be- und Entladen des Kofferraumes zu ermöglichen.This figure thus shows an example of the motor vehicle locking system according to the invention which can be remotely controlled by a transmitter signal I. The motor vehicle contains locks V, which can be unlocked by means of the transmitter S, e.g. to allow access to the vehicle and / or loading and unloading of the trunk.

Der transportable Sender / Schlüssel S sendet, z.B. ausgelöst durch Betätigung einer entsprechenden Drucktaste des Senders S, seine Sendersignale I zum im Kfz angebrachten Empfänger E, welcher die Verriegelung von zumindest einem Schloß V von zumindest einer Öffnung steuert, z.B. die Verriegelung des Schlosses V der Fahrertüre.The portable transmitter / key S sends, for example triggered by actuating a corresponding push button on the transmitter S, its transmitter signals I to the receiver E installed in the motor vehicle, which controls the locking of at least one lock V from at least one opening, for example the locking of the lock V Driver door.

Dieser Empfänger E kann mindestens zwei Zustände aufweisen, nämlich

  • ° einen ersten Zustand, in welchem er das betreffende Schloß V im verriegelten Zustand beläßt, und in welchem er gegebenenfalls auch das zuvor unverriegelte Schloß V verriegelt, sowie
  • ° einen zweiten Zustand, in welchem er, veranlaßt durch das Sendersignal I, zuläßt, daß die betreffenden Öffnung geöffnet wird.
This receiver E can have at least two states, namely
  • ° a first state in which he leaves the lock V in question in the locked state and in which he also locks the previously unlocked lock V, as well as
  • ° a second state in which it, caused by the transmitter signal I, allows the opening in question to be opened.

Es kommt viel zu oft vor, daß der Besitzer des Senders S mehr oder weniger noch in der Nähe des Kfz ist, daß also der Senders S und der Empfänger E in Reichweite zueinander sind, und daß während dessen aus Versehen der Sender S so bedient wird, daß er Sendersignale I ausstrahlt und dadurch versehentlich das betreffende Schloß V bzw. die betreffenden Schlösser V entriegelt, obwohl der betreffende Besitzer des Senders S in diesem Moment eigentlich gar nicht entriegeln will. Oft merkt dieser Besitzer gar nicht, daß er die Entriegelung versehentlich fernsteuerte, z.B. weil er sich irgendwo anlehnte und dabei versehentlich auf einen Betätigungsknopf des Senders S drückte, welcher seinerseits zufällig noch in Reichweite des Empfängers E war. Auch Unbefugte, z.B. Kinder, können mit dem Senders S spielen und sogar ohne Absicht die betreffenden Schlösser V dauerhaft entriegeln.It happens far too often that the owner of the transmitter S is more or less still in the vicinity of the motor vehicle, that is to say that the transmitter S and the receiver E are within easy reach of one another, and that the transmitter S is inadvertently operated during this process that it emits transmitter signals I and thereby accidentally unlocks the lock V or locks V in question, although the owner of the transmitter S concerned does not actually want to unlock it at this moment. Often this owner does not even notice that he accidentally controlled the release remotely, e.g. because he was leaning somewhere and accidentally pressed an actuation button on transmitter S, which in turn happened to be within range of receiver E. Unauthorized persons, e.g. Children can play with the transmitter S and even unlock the locks V permanently without intention.

Daher löst bei der Erfindung das Sendersignal I noch nicht das endgültige, andauernde Entriegeln der betreffenden Schlösser V aus. Zur Erschwerung von Diebstählen wird erfindungsgemäß angestrebt zu verhindern, daß ein solches ferngesteuertes Entriegeln der betreffenden Schlösser V zu länger andauerndem bzw. ständigen Entriegeln der betreffenden Schlösser V führt, wodurch anschließend jedermann in das Kfz eindringen könnte :
Dieses Ziel wird erfindungsgemäß dadurch erreicht, daß der Empfänger E nur für eine vorgegebene, vom Sendersignal I getriggerte Zeitspanne - z.B. für 30 Sekunden - in seinem zweiten Zustand verbleibt und das Öffnen der Öffnung zuläßt, - am Ende dieser Zeitspanne geht der Empfänger E aber automatisch zurück in seinen ersten Zustand, falls bis dahin noch nicht ordnungsgemäß das Öffnen der Türe bzw. das Betreten des Kfz zumindest eingeleitet wurde. Spätestens sobald der Empfänger E in seinen ersten Zustand übergeht, ist das Schloß V dauerhaft verriegelt und die Öffnung dauerhaft verschlossen.Therefore, in the invention, the transmitter signal I does not yet trigger the final, permanent unlocking of the locks V in question. To make theft more difficult, the aim according to the invention is to prevent such a remote-controlled unlocking of the locks V in question from leading to a longer or permanent unlocking of the locks V in question, as a result of which anyone could subsequently enter the motor vehicle:
This aim is achieved according to the invention in that the receiver E only remains in its second state for a predetermined period of time triggered by the transmitter signal I - for example for 30 seconds - and allows the opening to open - at the end During this period of time, the receiver E automatically returns to its first state if, by then, the opening of the door or entering the motor vehicle has not been properly initiated. At the latest as soon as the receiver E changes into its first state, the lock V is permanently locked and the opening is permanently closed.

Zur Erzeugung der Zeitspanne kann der Empfänger E z.B. ein entsprechend dimensioniertes monostabiles, vom Sendersignal I getriggertes Flipflop enthalten, oder der Empfänger E kann dazu z.B. einen - auch für weitere Zwecke ausnutzbaren - Prozessor mit einem Speicher sowie eine entspre-chend gestaltete Software enthalten, welche mehr oder weniger die Funktion jenes monostabilen Flipflop nachbildet.To generate the time period, the receiver E can e.g. contain a correspondingly dimensioned monostable flip-flop triggered by the transmitter signal I, or the receiver E can do this e.g. contain a processor, which can also be used for other purposes, with a memory and correspondingly designed software which more or less simulates the function of that monostable flip-flop.

Die Sicherheit gegen unbefugtes Öffnen und Betreten des Kfz kann zusätzlich dadurch gesteigert werden, daß am Kfz ein Kontakt, z.B. außen an der betreffenden Öffnung / Türe - vgl. K, angebracht wird. Wenn dieser Kontakt K kurz vor und/oder während des zweiten Zustandes des Empfängers E angefaßt oder betätigt wird, gibt dieser Kontakt K über eine entsprechende elektrische Verbindung ein Kontaktsignal C an den Empfänger E ab, wobei erst dieses Kontaktsignal C den Empfänger E endgültig veranlaßt, seinerseits das betreffende Schloß V zu entriegeln. Falls aber der Empfänger E bis zum Ende der Zeitspanne noch nicht jenes Kontaktsignal C erhielt, geht dieser Empfänger E automatisch von seinem zweiten Zustand in seinen ersten Zustand über. Bei dieser Weiterbildung ist die Sicherheit gegen unbefugtes Öffnen und Betreten des Kfz zusätzlich dadurch erhöht, daß - z.B. mangels "Klack"-Geräusch im Schloß V und mangels Bewegen eines evtl. im Türinneren angebrachten, mit dem Schloß verbundenen Stiftes A - für Außenstehende weder akustisch noch optisch leicht erkennbar ist, daß das Kfz (auch nach einem versehentlichen Aussenden des Sendersignales !) - jedenfalls für die Dauer der Zeitspanne - an sich leicht zu öffnen und zu betreten ist, solange nämlich der Empfänger E noch in seinem zweiten Zustand ist.The security against unauthorized opening and entering of the motor vehicle can additionally be increased by making contact on the motor vehicle, for example on the outside of the opening / door in question - cf. K, is attached. If this contact K is touched or actuated shortly before and / or during the second state of the receiver E, this contact K emits a contact signal C to the receiver E via a corresponding electrical connection, only this contact signal C finally causing the receiver E, in turn to unlock the lock V concerned. However, if the receiver E has not yet received that contact signal C by the end of the time period, this receiver E automatically changes from its second state to its first state. In this development, the security against unauthorized opening and entering the motor vehicle is additionally increased by the fact that - for example, a lack of "clack" noise in lock V and the lack of movement of a pin A attached to the inside of the door, connected to the lock - neither acoustically for outsiders is still visually easy to see that the vehicle (even after an accidental transmission of the transmitter signal!) - at least for the duration of the period - is easy to open and enter as long as the receiver E is still in its second state.

Man kann auf besonders einfache, für Außenstehende sehr unauffällige Weise den Kontakt K zum Öffnen der betreffenden Öffnung berühren bzw. betätigen, wenn der Kontakt K - in möglichst unauffälliger Weise - so mit dem Türgriff T verbunden wird, daß er beim Anfassen oder Betätigen des Türgriffes T das Kontaktsignal C an dem Empfänger E abgibt und damit das Entriegeln einleitet.You can touch or operate the contact K to open the relevant opening in a particularly simple, very inconspicuous way for outsiders if the contact K is connected to the door handle T in the most inconspicuous way possible so that it touches or actuates the door handle T outputs the contact signal C at the receiver E and thus initiates the unlocking.

Man kann bei der Erfindung auch noch auf andere Weise eine zusätzliche Sicherheit gegen unbefugtes Öffnen und Betreten des Kfz erreichen, wobei auch dann - mangels eines "Klack"-Geräusches im Schloß V und z.B. mangels Bewegen eines im Türinneren angebrachten, mit dem Schloß V verbundenen Stiftes A - für Außenstehende weder akustisch noch optisch erkennbar ist, daß das Kfz (auch nach einem versehentlichen Aussenden des Sendersignales !) - jedenfalls für die Dauer der Zeitspanne - an sich leicht zu öffnen und zu betreten ist :
Man kann diese Sicherheit nämlich auch dann erreichen, wenn der Empfänger E sofort nach dem Empfang des Sendersignales I das Schloß V entriegelt. Dazu kann man das Schloß V und/oder den Empfänger E so dimensionieren und/oder betreiben,

  • ° daß der Empfänger E schon beim Übergang von seinem ersten Zustand in seinen zweiten Zustand das Schloß V entriegelt, aber ohne jegliche für Außenstehende deutlich hörbaren Auswirkungen zu erzeugen (ohne "Klack-"Geräusch des Schlosses V) und ohne für Außenstehende optisch erkennbare Auswirkungen zu erzeugen, und
  • ° daß der Empfänger E, falls die Öffnung nicht geöffnet wird, das Schloß V nur wahrend der Dauer der Zeitspanne im entriegelten Zustand beläßt.
In the invention, additional security against unauthorized opening and entering of the motor vehicle can also be achieved in another way, even then - in the absence of a "clack" sound in the lock V and, for example, in the absence of movement of an attached inside the door, connected to the lock V. Pen A - for outsiders it is neither acoustically nor optically recognizable that the vehicle (even after an accidental transmission of the transmitter signal!) - at least for the duration of the period - is easy to open and to enter:
This security can also be achieved if the receiver E unlocks the lock V immediately after receiving the transmitter signal I. For this purpose, the lock V and / or the receiver E can be dimensioned and / or operated
  • ° that the receiver E unlocks the lock V already during the transition from its first state to its second state, but without producing any clearly audible effects for outsiders (without the "clack" sound of the lock V) and without visually recognizable effects for outsiders generate, and
  • ° that the receiver E, if the opening is not opened, leaves the lock V only in the unlocked state for the duration of the period.

Dieses zusätzliche Ziel kann man also dadurch erreichen, daß man eine spezielle Konstruktion bzw. Dimensionierung und einen speziellen Betrieb des Schlosses V und/oder des Empfängers E wählt. Dazu eignet sich z.B. eine entsprechende Schalldämpfung am Schloß V. Dazu eignet sich auch ein Verstärker V, welcher die Entriegelung so langsam durchführt, daß dies akustisch für Außenstehende nicht mehr deutlich hörbar ist. Das Aussenden des Sendersignales I löst bei dieser Weiterbildung der Erfindung also kein hörbares Geräusch, z.B. "Klacken", der Entriegelung aus, weil das Schloß V und/oder der Empfänger E entsprechend konstruiert und/oder betrieben werden.This additional goal can therefore be achieved by choosing a special design or dimensioning and a special operation of the lock V and / or the receiver E. Appropriate sound attenuation is suitable for this at the lock V. Also suitable is an amplifier V, which carries out the unlocking so slowly that it is no longer clearly audible acoustically for outsiders. In this development of the invention, the transmission of the transmitter signal I therefore does not trigger any audible noise, for example “clacking”, because the lock V and / or the receiver E are designed and / or operated accordingly.

Dieses zusätzliche Ziel kann man aber auch dann erreichen, wenn das Schloß V einen Stift A aufweist, welcher das zugehörende Schloß V - bei Zentralverriegelung evtl. sogar sämtliche Schlösser V sämtlicher Öffnungen gemeinsam - an sich durch Drücken auf den Stift A zu schließen und durch Ziehen an diesem Stift A zu öffnen gestattet; Außenstehende können an sich normalerweise leicht an der Stellung der Stifte A erkennen, ob der Kfz entriegelt oder verriegelt ist. Um dieses Erkennen zu verhindern, kann man zusätzlich einen Kontakt K anbringen, welcher, wenn er kurz vor und/oder während des zweiten Zustandes des Empfängers E angefaßt oder betätigt wird, ein Kontaktsignal C an den Empfänger E abgibt, wobei erst dieses dann entstandene Kontaktsignal C den Empfänger E endgültig veranlaßt, seinerseits den Stift A in die Stellung "entriegelt" zu bewegen. Der Empfänger E und/ oder das Schloß V wird dann so dimensioniert, daß das Schloß V zwar schon bei Beginn des zweiten Zustandes des Empfängers E völlig entriegelt wird, obwohl der Empfänger E noch nicht das Kontaktsignal C erhielt; vor dem Empfang des Kontaktsignales C bewegt aber der Empfänger E noch nicht den Stift A. Bei dieser Weiterbildung veranlaßt also erst das Kontaktsignal C, aber noch nicht das Sendersignal I, den Empfänger E, den Stift A sichtbar in die Stellung "entriegelt" zu bewegen.This additional goal can also be achieved if the lock V has a pin A, which locks the associated lock V - with central locking possibly even all locks V of all openings - by pressing on pin A and pulling allowed to open at this pin A; Outsiders can usually easily tell by the position of the pins A whether the vehicle is unlocked or locked. In order to prevent this detection, a contact K can additionally be attached, which, if it is touched or actuated shortly before and / or during the second state of the receiver E, emits a contact signal C to the receiver E, this contact signal only then arising C finally causes the receiver E to move the pin A to the "unlocked" position. The receiver E and / or the lock V is then dimensioned such that the lock V is completely unlocked even at the beginning of the second state of the receiver E, although the receiver E has not yet received the contact signal C; Before receiving the contact signal C, however, the receiver E does not yet move the pin A. In this development, the contact signal C, but not yet the transmitter signal I, causes the receiver E to move the pin A visibly into the “unlocked” position .

Bei mehreren Weiterbildungen der Erfindung ist also erreichbar, daß der Übergang des Empfängers E von seinem ersten in seinen zweiten Zustand - zumindest solange noch nicht der entsprechende Kontakt K bzw. Türgriff T berührt bzw. betätigt ist - für Außenstehende weder optisch noch akustisch zu erkennen ist, daß dann das betreffende Schloß V leicht zu entriegeln ist, oder daß dann das Schloß V durch das Sendersignal I bereits unmittelbar für die Dauer der Zeitspanne entriegelt ist, wobei bei allen Weiterbildungen der Empfänger E von seinem zweiten Zustand automatisch in seinen ersten Zustand übergeht und - spätestens dann - die Öffnung dauerhaft verriegelt, falls diese Öffnung während der Zeitspanne nicht ordnungsgemäß geöffnet wurde.In several further developments of the invention it can be achieved that the transition of the receiver E from its first to its second state - at least as long as the corresponding contact K or door handle T has not yet been touched or actuated - is neither visually nor acoustically recognizable to outsiders , that the relevant lock V is then easy to unlock, or that the lock V is then unlocked directly by the transmitter signal I for the duration of the time period, with the receiver E automatically changing from its second state to its first state in all further developments, and - at the latest - the opening is permanently locked if this opening has not been opened properly during the period.
