Abstract

Selon un procédé d'une installation centrale de verrouillage à télécommande pour véhicules à moteur, on utilise un émetteur capable de transmettre des signaux codés - par exemple, des signaux acoustiques aux ultra-sons, optiques aux IR et/ou des ondes de haute fréquence OUC - à un récepteur agencé dans ou sur le véhicule. Lorsque l'installation de verrouillage centralisé est actionnée pour la première fois, elle est initialisée ou réinitialisée avant son actionnement suivant afin d'annuler le code antérieur. Le code utilisable à l'avenir, ou le nouveau code utilisable à l'avenir lors d'un changement du code, est déterminé pour la première fois ou modifié en mettant le récepteur dans un état dans lequel il peut être (ré)initialisé, par exemple au moyen d'un code spécial de commande. Lors de sa (ré)initialisation, le récepteur actionne un affichage déjà disponible du véhicule à moteur, afin d'indiquer que le récepteur est dans un état où il peut être ré(initialisé).According to a method of a central remote control locking installation for motor vehicles, a transmitter is used capable of transmitting coded signals - for example, acoustic to ultrasonic, optical to IR and/or high frequency waves OUC - to a receiver arranged in or on the vehicle. When the central locking installation is actuated for the first time, it is initialized or reset before its next actuation in order to cancel the previous code. The code usable in the future, or the new code usable in the future when changing the code, is determined for the first time or modified by putting the receiver in a state in which it can be (re)initialized, for example by means of a special order code. During its (re)initialization, the receiver activates an already available display of the motor vehicle, in order to indicate that the receiver is in a state where it can be re(initialized).

Description

Verfahren zum Betrieb einer fernbedienbaren Zentralverriegelung eines Fahrzeuges Method for operating a remote-controlled central locking system of a vehicle
Die Erfindung betrifft eine Verbesserung des speziellen Verfah¬ rens, das im Oberbegriff des Hauptanspruches definiert und für sich vorbekannt ist. Die Erfindung betrifft nämlich eine Ver¬ besserung des z.B. in - DE-Al-32 25 754 und in einem Teil des dort zitierten Standes der Technik ange¬ gebenen Verfahrens, also dem Betrieb des Empfängers im Rahmen der (Re-)Initialisierung des Sender-Empfänger-Systems, d.h. also im Rahmen der (Neu-)Fiπdung bzw. (Neu-)Festsetzung des zukünftig benutzbaren Code für die Betätigung der Verriegelung.The invention relates to an improvement of the special procedural method, which is defined in the preamble of the main claim and is known per se. The invention namely relates to an improvement of e.g. in DE-Al-32 25 754 and in a part of the state of the art cited therein, i.e. the operation of the receiver as part of the (re) initialization of the transmitter-receiver system, i.e. So in the context of the (re) fiπdung or (re) setting the future usable code for the actuation of the lock.
Bei bekannten Verfahren werden zusätzliche Mittel, z.B. ein Lämpchen bzw. eine LED, speziell zur Anzeige des Zustandes des Empfängers angebracht, damit der Benutzer weiß, ob er die (Re-) Initialisierung beginnen kann oder ob die (Re-)Initialisierung geglückt ist.In known methods additional means, e.g. a light or an LED, specially designed to indicate the status of the receiver, so that the user knows whether he can start the (re) initialization or whether the (re) initialization has been successful.
Die Aufgabe der Erfindung ist, den zusätzlichen Aufwand, der zum (Re-)Initialisieren dient, möglichst klein zu machen. Diese Aufgabe wird durch die im Hauptanspruch definierten Maßnahmen gelöst.The object of the invention is to make the additional effort that is used for (re) initializing as small as possible. This task is solved by the measures defined in the main claim.
Die in den Unteransprüchen genannten zusätzlichen Maßnahmen ge¬ statten ebenfalls, zusätzlichen Aufwand möglichst klein zu machen. Es gestatten nämlich die Maßnahmen gemäß Patentanspruch 2, normalerweise ohnehin bei einer Zentralverriegelung vorhan¬ dene Knöpfe zur Anzeige der Bereitschaft des Empfängers, auf auf einen neuen Code bzw. auf eine neue Codemenge festgelegt zu werden, mitauszunutzen, 3, normalerweise ohnehin bei einer Zentralverriegelung vorhan¬ dene Knöpfe zur Anzeige der erfolgten (Re-)Initialisierung des Empfängers mitauszunutzen, sowie 4 und 5, zur Steuerung des Empfängers in seine Bereitschaft,The additional measures mentioned in the subclaims also allow additional effort to be minimized. This is because the measures according to patent claim 2 allow the use of buttons for indicating the willingness of the receiver to be set to a new code or to a new code quantity, which are normally present anyway in the case of a central locking system, 3, normally already existing anyway in the case of a central locking system ¬ use the buttons to indicate the (re) initialization of the receiver, and 4 and 5, to control the receiver in its readiness,
(re-)initialisiert zu werden, die ohnehin in einem Fahrzeug vorhandene Zündung bzw. den ohnehin benötigten Zündschlüssel mitauszunutzen.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 fern¬ bedienbaren Zentralverriegelung eines Fahrzeuges. Zur Fernbedie¬ nung 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 is used for remote control, which encoded signals - e.g. acoustically by means of ultrasound, optically by means of IR and / or by means of VHF radio-frequency waves - can be transmitted 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 erst¬ maligen Betätigung der Zentralverriegelung muß also der Empfän- ger, im allg. auch gleichzeitig noch der betreffende Sender, initialisiert werden, - bzw. es muß vor der nächsten Betätigung der Zentralverriegelung, zur wirksamen Annullierung des bishe¬ rigen 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. thereafter the same code, 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 actuated for the first time, the receiver, generally also the transmitter concerned, must be initialized - or before the central locking system is actuated again, in order to effectively cancel the previous code or the previous code amount, the receiver is reinitialized and in this case 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 Verfah¬ ren zur (Re-)Initialisierung - der Empfänger, z.B. mittels ei¬ nes speziellen Steuercode, in einen Zustand gesteuert, in wel¬ chem 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. Der Empfänger sollte möglichst der (re-)initialisierenden Per¬ son anzeigen, daß der zur (Re-)Initialisierung nötige Empfänger¬ zustand gegeben ist. Dazu benötigt die Erfindung besonders we¬ nig 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-)Initia- lisierungszustand erkennbar ist. Der Empfänger zeigt also mit¬ tels ohnehin vorhandener Mittel an, daß der Empfänger einen entsprechenden (Re-)Initialisierungszustand aufweist.For 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 used to (re) determine the code or the code set is ready i. generally by storing the signals then received directly or recoded in a ROM of the receiver. The recipient should indicate to the (re) initializing person, if possible, that the recipient state necessary for the (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 therefore indicates by means of means already present that the receiver has a corresponding (re) initialization state.
Besonders wenig zusätzlicher Aufwand für diese Anzeige wird be¬ nötigt, wenn bei Beginn des (Re-)Initialisierens die Anzeige durch eine sieht- und/oder hörbare Betätigung der ohnehin vor- handenen 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 Empfän¬ ger auch später bei der laufenden Betätigung der Zentralverrie¬ gelung 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 present anyway, e.g. by moving the push buttons attached to the doors that open and close the doors, which i. in any case, are also indirectly actuated by the receiver later, when the central locking is being operated.
Ebensowenig Aufwand wird zur Anzeige des Empfängers, daß die (Re-)Initialisierung geglückt ist, benötigt, wenn der Empfänger nach erfolgreicher (Re-)Initialisierung sieht- und/oder hörbar die Zentralverriegelung betätigt, also z.B. (auch) dann die in den Türen angebrachten, die Türen normalerweise öffnenden und schließenden Druckkπöpfe betätigt.Just as little effort is required to indicate to the recipient that the (re) initialization has been successful if the recipient sees and / or hears the central locking system after successful (re) initialization, e.g. (also) then the pressure heads attached in the doors, which normally open and close the doors, are actuated.
Die Erfindung gestattet darüber hinaus, mit besonders wenig Auf¬ wand die (Re-)Initialisierung einzuleiten. Dazu kann nämlich der der Empfänger z.B. sogar mittels einer normalerweise unüb¬ lichen Betätigung des Zündschlüssels, nämlich z.B. mittels raschem zehnmaligen Ein- und Ausschaltens der Zündung, in den Zustand des (Re-)Initialisierens gesteuert werden; dann benö¬ tigt man dann nur einen meistens im Empfänger ohnehin vorhande- nen 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 Zünd- Schlüssel in seinen Zustand gesteuert werden, in welchem er zur (Re-)Initialisierung bereit ist : Z.B. kann dazu der Zünd¬ schlüssel (einmal oder mehrmals in bestimmtem Rhythmus hinter¬ einander) in eine besondere, nur beim Parken mögliche Stellung gedreht werden, wonach der Empfänger, z.B. während einer be¬ stimmten 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 that is required is a counter, which is usually present in the receiver anyway, and which 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 The key can be controlled in its state in which it is ready for (re) initialization: For example, the ignition key can be turned (once or several times in succession in a certain rhythm) into a special position that is only possible when parking, after which the receiver is ready for (re) initializing, for example during a certain subsequent time period.
