Abstract

A process is disclosed for operating a remote controlled central locking installation of motor vehicles by means of a transmitter able to transmit coded signals - for example, acoustic ultrasonic signals, optic IR signals and/or USW-high frequency waves - to a receiver arranged in or on the vehicle. When the central locking installation is operated for the first time, it is initialised, or it is re-initialised before it is operated again in order to cancel the previous code. The code that will be used in the future, or when the code is changed the new code that will be used in the future, is set for the first time or reset by placing the receiver, for example by means of a special control code, in a state in which it can be (re)initialised. During (re)initialisation, the receiver activates a display that is already available in the vehicle in order to indicate that the receiver is in a state in which it can be (re)initialised.

Description

Die Erfindung betrifft eine Verbesserung des speziellen Verfahrens für den Betrieb des Empfängers einer fernbedienbaren Zentralverriegelung während der Initialisierung bzw. Re-Initialisierung des Sender-Empfänger-Systems. Die Erfindung soll also im Rahmen der (Neu-)Findung bzw. (Neu-)Festsetzung des zukünftig benutzbaren Code für die Betätigung der Verriegelung angewendet werden.The invention relates to an improvement of the special method for operating the receiver of a remote-controlled central locking system during the initialization or re-initialization of the transmitter-receiver system. The invention is therefore intended to be used in the context of the (re) finding or (re) setting of the code which can be used in the future for actuating the lock.

Dabei geht die Erfindung von jenem Verfahren aus, das in den Oberbegriffen der Patentansprüche 1 und 4 definiert und durch die

  • FR-A-2 580 128
vorbekannt ist. Bei diesem Stand der Technik ist eine spezielle, vom Empfänger gesteuerte Lumineszenzdiode als Anzeigeorgan vorgesehen, um der (re-)initialisierenden Person im Rahmen einer taktgerechten Bedienerführung anzuzeigen, wann diese Person dem Empfänger jeweils (wieder) einen Einzelimpuls des aus einer längeren Einzelimpulsserie gebildeten Code übertragen kann.The invention is based on the method defined in the preambles of claims 1 and 4 and by
  • FR-A-2 580 128
is known. In this prior art, a special luminescence diode controlled by the receiver is provided as a display element in order to indicate to the (re) initializing person in the context of a timely operator guidance when this person each (again) sends a single pulse of the code formed from a longer individual pulse series to the receiver can transmit.

Die Erfindung dient aber nicht zur taktgerechten Bedienerführung der (re-)initialisierenden Person, sondern dazu, um diese Person - unabhängig von einer evtl. zusätzlichen taktgerechten Einzelimpulseingabe - generell bei der (Re-Initialisierung zu unterstützen. Die Erfindung eignet sich also auch für eine Zentralverriegelung, bei welcher diese Person Zur (re-)Initialisierung überhaupt keine taktgerechte Bedienerführung brauchte. Die Erfindung benötigt auch kein Anzeigeorgan, das speziell für die betreffende Zentralverriegelung als zusätzliche Ausrüstung zur Unterstützung der (Re-)Initialisierung angebracht wurde.However, the invention does not serve to provide the (re-) initializing person with timely operator guidance, but rather to generally support this person in the (re-initialization) regardless of any additional timely individual pulse input. The invention is therefore also suitable for one Central locking , in which this person did not need any timely operator guidance for (re) initialization, nor does the invention require a display element that was attached specifically for the central locking in question as additional equipment to support the (re) initialization.

Es gibt weitere Zentralverriegelungen mit speziell für sie angebrachten Anzeigen. Vgl. z.B.

  • EP-A2-395 596,
worin beschrieben ist, daß im Sender LED-Anzeigen angebracht sind, welche während des laufenden Normalbetriebes der Zentralverriegelung der benutzenden Person anzeigen, daß sein Kfz ordentlich verriegelt und die Alarmanlage eingeschaltet wurde. Dort ist u.a. auch beschrieben, daß die betreffende Alarmanlege eine zusätzliche LED-Anzeige im Fahrgastraum einschalten, sowie im Alarmfall z.B. auch die Hupe oder die Frontscheinwerfer einschalten und evtl. die Zündung bzw. Benzinpumpe abschalten kann.There are other central locking systems with displays specially designed for them. See e.g.
  • EP-A2-395 596,
which describes that LED indicators are attached in the transmitter, which indicate to the user during normal normal operation of the central locking system that his vehicle has been properly locked and the alarm system has been switched on. There it is also described, inter alia, that the alarm system in question switches on an additional LED display in the passenger compartment, and in the event of an alarm, for example, can also switch on the horn or the headlights and possibly switch off the ignition or fuel pump.

Die Erfindung betrifft aber nicht eine mehr oder weniger geschickte Kombination einer Zentralverriegelung mit einer Alarmanlage, obgleich die Erfindung eine solche Kombination im Prinzip zuläßt, wobei die Erfindung eben auch kein Anzeigeorgan benötigt, das speziell für die betreffende Zentralverriegelung als zusätzliche Ausrüstung zur Unterstützung der Bedienung des Senders oder des Empfängers angebracht ist.However, the invention does not relate to a more or less clever combination of a central locking system with an alarm system, although the invention allows such a combination in principle, the invention also not requiring a display element specifically for the central locking system in question as additional equipment to support the operation of the Sender or the recipient is attached.

Bei Alarmanlagen ist es seit langem üblich, die Hupe und die Frontscheinwerfer auszunutzen - allgemeiner formuliert: auf große Entfernungen hin stark auffallende, ohnehin aus anderen Gründen im Kfz vorhandene Anzeigen auszunutzen - , um einen Alarmfall anzuzeigen.In the case of alarm systems, it has long been customary to use the horn and the headlights - in more general terms: to use advertisements that are noticeable over long distances and are present in the vehicle anyway for other reasons - to indicate an alarm.

Die Erfindung betrifft aber keine Alarmanlage, obwohl die Erfindung zuläßt, daß zusätzlich eine Alarmanlage im Fahrzeug angebracht wird.However, the invention does not concern an alarm system, although the invention allows an alarm system to be additionally installed in the vehicle.

Es sind auch sehr unterschiedliche Verfahren zur (Re-)Initialisierung ferngesteuerter Zentralverriegelungen für sich bekannt, wobei besonders diese Verfahren teilweise technisch besonders kompliziert sind, besonders wenn ein sog. Wechselcode verwendet werden soll, der bekanntlich einen besonders großen Schutz gegen unbefugtes Betätigen der Schlösser bieten kann, oder gar wenn ein Wechselcode mit Dialogbetrieb zwischen dem Sender und dem Empfänger verwendet werden soll. Nur beispielhaft wird dazu auf die

  • DE-A1-32 25 754
hingewiesen.There are also very different methods for the (re) initialization of remote-controlled central locking systems, these methods in particular being technically particularly complicated, especially if a so-called change code is to be used, which is known to offer particularly great protection against unauthorized actuation of the locks can, or even if a change code with interactive mode is to be used between the sender and the receiver. This is only exemplified by the
  • DE-A1-32 25 754
pointed out.

Die Erfindung ist nicht auf einen bestimmten Code, auch nicht auf einen bestimmten Wechselcode beschränkt. Die Erfindung läßt nämlich die Verwendung von beliebigen Codes zu.The invention is not restricted to a specific code, nor to a specific change code. The invention allows the use of any code.

Es ist außerdem bekannt, daß gerade in der Kfz-Branche seit jeher eines der obersten Ziele nahezu aller Entwickler ist, Kosten zu sparen bzw. den Aufwand weiter zu verringern, also auch möglichst viele Bauteile zu vereinfachen bzw. nach Möglichkeit ganz wegzulassen, ohne die Betriebsicherheit oder dem Komfort zu verschlechtern. Angesichts dieser intensiven Anstrengungen der Entwickler ist es bekanntlich nicht mehr eine alltägliche, mit dem fachmännischen Wissen leicht zu lösende Aufgabe, weitere spürbare Einsparungen ohne Verschlechterung der Betriebssicherheit und des Komforts zu erreichen.It is also known that, especially in the automotive industry, one of the primary goals of almost all developers has always been to save costs or reduce effort, i.e. to simplify as many components as possible or to omit them as far as possible without the Operational safety or comfort deteriorate. In view of these intensive efforts by the developers, it is known that it is no longer an everyday task that can be easily solved with specialist knowledge to achieve further noticeable savings without a deterioration in operational safety and comfort.

Die Aufgabe der Erfindung,

  • den Aufwand an solchen Bauteilen besonders gering zu machen, welcher dazu dient, der (re-)initialisierenden Person die (Re-)Initialisierung der Zentralverriegelung zu erleichtern,
  • aber dieser Person trotzdem die Sicherheit zu geben, daß sie die (Re-)Initialisierung richtig durchführt,
wird durch die in den unabhängigen Patentansprüchen 1 und 4 definierten Maßnahmen gelöst. Die Erfindung gestattet also mit einem ganz besonders geringen Aufwand zu vermeiden, daß jene Person keine ausreichende Kontrolle und Sicherheit hat, ob ihr Sender einwandfrei (re-)initialisiert wird.The object of the invention
  • to make the expenditure on such components particularly low, which serves to facilitate the (re) initializing person the (re) initialization of the central locking,
  • but to give this person the security that they are performing the (re) initialization correctly,
is solved by the measures defined in independent claims 1 and 4. The invention thus allows, with very little effort, to prevent that person from having inadequate control and certainty as to whether his transmitter is being properly (re) initialized.

Aber sogar alle die in den Patentansprüchen 1 bis 5 genannten speziellen Maßnahmen gestatten, die genannte Aufgabe der Erfindung zu lösen, und zwar besonders den zusätzlichen Aufwand zur Unterstützung der die (Re-)Initialisierung durchführenden Person möglichst klein zu machen. Es gestatten nämlich die Maßnahmen gemäß des Patentanspruch

  • 1, auf simple Weise dieser Person anzuzeigen, daß der Empfänger der Zentralverriegelung zur (Re-)Initialisierung wirklich auch bereit war und nun einwandfrei (re-)initialisiert ist,
  • 2, das Betätigen der Zentralverriegelung zur Anzeige der Bereitschaft des Empfängers, auf einen neuen Code bzw. auf eine neue Codemenge festgelegt zu werden, mitauszunutzen,
  • 3, normalerweise ohnehin bei einer Zentralverriegelung vorhandene Knöpfe zur Anzeige der erfolgten (Re-)Initialisierung des Empfängers mitauszunutzen, sowie
  • 4 und 5, zur Steuerung des Empfängers in seine Bereitschaft, (re-)initialisiert zu werden, die ohnehin in einem Fahrzeug vorhandene Zündung bzw. den ohnehin benötigten Zündschlüssel mitauszunutzen.
But even all the special measures mentioned in claims 1 to 5 allow the stated object of the invention to be achieved, particularly the additional effort to make the (re) initialization person as small as possible. This is because the measures according to the patent claim allow
  • 1, to simply indicate to this person that the central locking receiver was really ready for (re) initialization and is now properly (re) initialized,
  • 2, to take advantage of the actuation of the central locking to indicate the readiness of the receiver to be set to a new code or to a new code quantity,
  • 3, normally also use existing buttons for central locking to indicate the (re) initialization of the receiver, and
  • 4 and 5, to control the receiver in its readiness to be (re) initialized, to take advantage of the ignition that is already present in a vehicle or the ignition key that is required anyway.

Die Erfindung betrifft also ein Verfahren zum Betrieb einer fernbedienbaren Zentralverriegelung eines Fahrzeuges. Zur Fernbedienung dient ein Sender, der codierte Signale - z.B. akustisch mittels Ultraschall, optisch mittels IR und/oder mittels UKW-Hochfrequenzwellen - zu einem im oder am Fahrzeug angebrachten Empfänger übertragen kann.The invention thus relates to a method for operating a remote-controlled central locking system of a vehicle. A transmitter that uses coded signals - e.g. acoustically by means of ultrasound, optically by means of IR and / or by means of VHF radio frequency waves - to a receiver mounted in or on the vehicle.

Der für die normale Betätigung der Zentralverriegelung benutzte Code muß aber zuerst für sich festgelegt werden, gleichgültig, ob ein sog. Festcode, also danach ständig derselbe Code, oder ein Wechselcode, also danach ein laufend nach einem bestimmten Schema Wechselnder Code, benutzt werden soll. Diese Festlegung nennt man Initialisieren bzw. Re-Initialisieren. Vor der erstmaligen Betätigung der Zentralverriegelung muß also der Empfänger, im allg. auch gleichzeitig noch der betreffende Sender, initialisiert werden, - bzw. es muß vor der nächsten Betätigung der Zentralverriegelung, zur wirksamen Annullierung des bisherigen Code bzw. der bisherigen Codemenge, der Empfänger re-initialisiert werden und hierbei i.allg. auch noch der Sender re-initialisiert werden. Durch diese (Re-)Initialisierung wird also bei Benutzung eines Festcode der zukünftig benutzbare Code, bzw. bei Benutzung eines Wechselcode die betreffende zukünfig benutzbare Codemenge, festgelegt.However, the code used for the normal operation of the central locking system must first be set independently, regardless of whether a so-called fixed code, i.e. the same code thereafter, or an alternating code, i.e. a code that changes continuously according to a certain scheme, is to be used. This definition is called initializing or re-initializing. Before the central locking system is operated for the first time, the receiver, generally also the transmitter in question, must be initialized - or the receiver must be canceled before the central locking system is operated again, in order to effectively cancel the previous code or code quantity be reinitialized and generally the transmitter can also be re-initialized. This (re) initialization thus defines the code that can be used in the future when using a fixed code, or the relevant amount of code that can be used in the future when using an alternating code.

Zur Initialisierung wird also - auch bei den bekannten Verfahren zur (Re-)Initialisierung - der Emfänger, z.B. mittels eines speziellen Steuercode, in einen Zustand gesteuert, in welchem er zur (Neu-)Festlegung des Code bzw. der Codemenge bereit ist, i. allg. indem er die dann empfangenen Signale unmittelbar oder umcodiert in einem ROM des Empfängers speichert.For the initialization - also in the known methods for (re) initializing - the receiver is controlled, for example by means of a special control code, into a state in which it is ready for the (new) definition of the code or the code amount, i . generally by storing the signals then received directly or recoded in a ROM of the receiver.

Der Empfänger sollte möglichst der (re-)initialisierenden Person anzeigen, daß der zur (Re-)Initialisierung nötige Empfängerzustand gegeben ist. Dazu benötigt die Erfindung besonders wenig Aufwand. Bei der Erfindung steuert nämlich der Empfänger zur Anzeige, daß er im gewünschten Zustand ist, eine im KFZ ohnehin aus anderen Gründen vorhandene Anzeige in einer Weise, welche der Person als typisch für den gewünschten (Re-)Initialisierungszustand erkennbar ist. Der Empfänger zeigt also mittels ohnehin vorhandener Mittel an, daß der Empfänger einen entsprechenden (Re-)Initialisierungszustand aufweist.The recipient should indicate to the (re) initializing person, if possible, that the recipient state required for (re) initialization is present. For this purpose, the invention requires particularly little effort. In the case of the invention, the receiver, in order to indicate that it is in the desired state, controls a display which is present in the vehicle anyway for other reasons in a manner which the person can recognize as being typical of the desired (re) initialization state. The receiver thus indicates by means that are present anyway that the receiver has a corresponding (re) initialization state.

Besonders wenig zusätzlicher Aufwand für diese Anzeige wird benötigt, wenn bei Beginn des (Re-)Initialisierens die Anzeige durch eine sicht- und/oder hörbare Betätigung der ohnehin vorhandenen Zentralverriegelung dargestellt wird, also z.B. durch das Bewegen der in den Türen angebrachten, die Türen öffnenden und schließenden Druckknöpfe, die i. allg. ohnehin vom Empfänger auch später bei der laufenden Betätigung der Zentralverriegelung mittelbar betätigt werden.Particularly little additional effort is required for this display if, at the start of the (re) initialization, the display is shown by a visible and / or audible actuation of the central locking system that is already present, e.g. by moving the push buttons attached to the doors that open and close the doors, which i. anyway can be operated indirectly later by the receiver when the central locking system is operated.

Ebensowenig Aufwand wird zur Anzeige des Empfängers, daß die (Re-)Initialisierung geglückt ist, benötigt, wenn der Empfänger nach erfolgreicher (Re-)Initialisierung Sicht- und/oder hörbar die Zentralverriegelung betätigt, also z.B. (auch) dann die in den Türen angebrachten, die Türen normalerweise öffnenden und schließenden Druckknöpfe betätigt.Just as little effort is required to indicate to the receiver that the (re) initialization has been successful if the receiver actuates the central locking system visibly and / or audibly after successful (re) initialization, e.g. (also) then the push buttons attached in the doors, which normally open and close the doors, are actuated.

Die Erfindung gestattet darüber hinaus, mit besonders wenig Aufwand die (Re-)Initialisierung einzuleiten. Dazu kann nämlich der der Empfänger z.B. sogar mittels einer normalerweise unüblichen Betätigung des Zündschlüssels, nämlich z.B. mittels raschem zehnmaligen Ein- und Ausschaltens der Zündung, in den Zustand des (Re-)Initialisierens gesteuert werden; dann benötigt man dann nur einen meistens im Empfänger ohnehin vorhandenen Zähler, der die Anzahl der Zündschlüsselbetätigungen, z.B. vor dem Anlassen des Motors, überprüft. Der Empfänger kann auch durch andere normalerweise unübliche Tätigkeiten mit dem Zündschlüssel in seinen Zustand gesteuert werden, in welchem er zur (Re-)Initialisierung bereit ist : Z.B. kann dazu der Zündschlüssel (einmal oder mehrmals in bestimmtem Rhythmus hintereinander) in eine besondere, nur beim Parken mögliche Stellung gedreht werden, wonach der Empfänger, z.B. während einer bestimmten folgenden Zeitperiode, zum (Re-)Initialisieren bereit ist.The invention also allows the (re) initialization to be initiated with particularly little effort. For this purpose, the receiver can even be controlled into the state of (re) initializing, for example, by means of a normally unusual actuation of the ignition key, namely, for example, by quickly switching the ignition on and off ten times; then all you need is a counter that is usually already present in the receiver and checks the number of key actuations, for example before the engine is started. The receiver can also be used for other normally unusual activities with the ignition key be controlled in its state in which it is ready for (re) initialization: For example, the ignition key (once or several times in succession) can be turned into a special position that is only possible when parking, after which the receiver, e.g. during a certain subsequent period of time is ready for (re) initialization.
