Description

Vorliegende Erfindung betrifft eine codierte Fernsteuerung mit Codeumstellung von der Art, die einen Sender mit Einrichtungen zur Aussendung und Übermittlung einer codierten Nachricht sowie einen Empfänger mit Einrichtungen zum Empfang der vom Sender ausgestrahlten Nachricht enthält, weiterhin Einrichtungen zum Vergleich der genannten Nachricht mit einer gespeicherten Nachricht sowie Einrichtungen zur Aussendung eines Steuersignals im Falle der Übereinstimmung zwischen der empfangenen Nachricht und der gespeicherten Nachricht.The present invention relates to a coded remote control with code conversion of the type which contains a transmitter with devices for transmitting and transmitting a coded message and a receiver with devices for receiving the message emitted by the transmitter, further devices for comparing the said message with a stored message and Means for sending a control signal in the event of a match between the received message and the stored message.

Derartige Fernsteuerungen werden insbesondere in der Automobilindustrie zur Steuerung der Verriegelung/Entriegelung von Türen, eines Alarms, zur Steuerung von Fahrzeugblockierelementen usw. eingesetzt.Such remote controls are used in particular in the automotive industry to control the locking / unlocking of doors, an alarm, to control vehicle blocking elements, etc.

Üblicherweise sind Sender und Empfänger mit einem gleichen Festcode kombiniert, was zahlreiche Schwierigkeiten bei der Bandmontage bewirkt, bei der Sender und Empfänger getrennt sind. Darüber hinaus bringt die Anordnung eines neuen Senders, falls der alte verlorengeht, zerstört wird oder ein neuer Sender erforderlich wird, die Notwendigkeit einer kostspieligen Installation und einen schwierigen Eingriff mit sich.Usually, the transmitter and receiver are combined with the same fixed code, which causes numerous difficulties in tape assembly, in which the transmitter and receiver are separate. In addition, the arrangement of a new transmitter if the old one is lost, destroyed, or a new transmitter becomes necessary entails the need for expensive installation and difficult intervention.

Um dieser Schwierigkeit abzuhelfen, wurde vorgeschlagen, die Fernsteuerung mit Programmiereinrichtungen auszustatten, z.B. mit einem Schalter, der vom Benutzer betätigt werden kann und die Programmierung einer neuen codierten Nachricht ermöglicht, die gespeichert werden kann (2.B. FR-A-2494534).To remedy this difficulty, it has been proposed to equip the remote control with programming devices, e.g. with a switch that can be operated by the user and enables the programming of a new coded message that can be saved (2.B. FR-A-2494534).

Eine derartige Anordnung bringt den erheblichen Nachteil mit sich, daß der gespeicherte Code durch einen unbefugten Dritten umgestellt werden kann, der über einen neuen Sender verfügt und Zugriff auf die Programmiereinrichtungen hat. Selbst wenn die Programmiereinrichtungen nur bei Aussendung der bereits gespeicherten Nachricht wirksam sein können, wie es eine Variante der vorgeschlagenen Vorrichtung vorsieht, besteht doch weiterhin die Gefahr einer Codeumstellung durch Dritte.Such an arrangement has the considerable disadvantage that the stored code can be changed by an unauthorized third party who has a new transmitter and has access to the programming devices. Even if the programming devices can only be effective when the already stored message is sent, as is provided by a variant of the proposed device, there is still the risk of a code change by third parties.

Vorliegende Erfindung hat den Zweck, diese bei den bekannten Vorrichtungen auftretenden Schwierigkeiten zu beseitigen.The present invention has the purpose of eliminating these difficulties encountered in the known devices.

Zu diesem Zweck ist die Fernsteuerung gemäß der Erfindung dadurch gekennzeichnet, daß der Empfänger im Speicher einen Festcode enthält, der vorher festgelegt wurde und dessen Empfang nicht die Sendung des genannten Steuersignals bewirkt, sondern Einrichtungen zur Eingabe eines Steuercodes in dem genannten Speicher betätigt, der nach dem genannten Festcode empfangen wurde, wobei der genannte und vorher festgelegte Festcode durch einen programmierbaren Sender gesendet wird.For this purpose, the remote control according to the invention is characterized in that the receiver contains a fixed code in the memory which has been defined beforehand and whose reception does not cause the control signal mentioned to be transmitted, but rather actuates means for entering a control code in the memory mentioned, which after said fixed code was received, said fixed predetermined code being transmitted by a programmable transmitter.

Der programmierbare Sender arbeitet vorzugsweise mit Codierrädern oder einer Tastatur. In einer Ausführungsart der Erfindung besteht der Speicher des Empfängers aus einem Block von Registern, von denen das erste den genannten und vorher festgelegten Festcode enthält, während der Empfang des genannten Festcodes die Öffnung auf ein Unterprogramm zur Verschiebung und Codierung des zweiten Registers bewirkt.The programmable transmitter preferably works with coding wheels or a keyboard. In one embodiment of the invention, the memory of the receiver consists of a block of registers, the first of which contains said and predetermined fixed code, while the reception of said fixed code opens a subroutine for shifting and coding the second register.

Das System gemäß der Erfindung ermöglicht die Codierung eines Empfängers nach Auslieferung des Fahrzeuges mit Hilfe eines Senders mit beliebigem Code, in dem der vorher speziell für das Fahrzeug festgelegte Festcode mit Hilfe des programmierbaren Senders gesendet wird. Dieser programmierbare Sender, der sich nur im Besitz befugter Reparaturunternehmen befindet, ermöglicht somit aufgrund der Fernsteuerung selbst die Ferneingabe eines Codes in den Speicher, der diesen nicht enthält oder der einen anderen Code als den des Senders enthält.The system according to the invention enables the coding of a receiver after delivery of the vehicle using a transmitter with any code, in which the fixed code previously defined specifically for the vehicle is sent using the programmable transmitter. This programmable transmitter, which is only owned by authorized repair companies, therefore enables remote entry of a code into the memory which does not contain it or which contains a code other than that of the transmitter.

Der Vorgang ist der gleiche, wenn der Speicher bereits einen Code enthält und der Benutzer diesen Code umstellen will. Dies ist beispielsweise der Fall bei Verlust oder Zerstörung des Senders. Der Benutzer kann dann einen neuen Sender mit beliebigem Code erwerben, der anstelle des alten Codes in den Speicher des Empfängers eingegeben werden kann, sofern ein programmierbarer Speicher und der vorher festgelegte Festcode des Fahrzeugs zur Verfügung steht. Dieser Festcode stellt somit einen Speicherzugriffscode dar.The process is the same if the memory already contains a code and the user wants to change this code. This is the case, for example, if the transmitter is lost or destroyed. The user can then purchase a new transmitter with any code that can be entered into the receiver's memory instead of the old code, provided a programmable memory and the predetermined fixed code of the vehicle are available. This fixed code thus represents a memory access code.

Im Falle eines Registerblocks, der mehrere Steuercodes enthalten kann, z.B. die jeweiligen Codes für verschiedene Benutzer, ist der Vorgang der gleiche. Durch Eingabe eines neuen Codes wird der im letzten Register enthaltene Code aus dem Speicher ausgegeben.In the case of a register block that can contain several control codes, e.g. the respective codes for different users, the process is the same. By entering a new code, the code contained in the last register is output from the memory.

Der programmierbare Sender ist ein einfaches und kostengünstiges Gerät, dessen Benutzung für die Vertragshändler einfach und wirtschaftlich ist.The programmable transmitter is a simple and inexpensive device, which the dealers can use easily and economically.

Die weiter oben beschriebene systematische Verschiebung kann bei Verlust eines Senders, dessen Code gespeichert wurde, eine Schwierigkeit darstellen. Tatsächlich kann der nutzlos gewordene Code im Speicher nicht direkt durch den Code eines neuen Senders ersetzt werden, da der Speicherplatz nicht bekannt ist. Es muß somit nicht nur der Code dieses neuen Senders neu eingegeben werden, sondern auch die Codes sämtli cher anderen Sender, die somit noch gültig sind. Dieser Vorgang ist zeitraubend und wenig flexibel.The systematic shift described above can be difficult if a transmitter whose code has been stored is lost. In fact, the useless code in the memory cannot be directly replaced by the code of a new transmitter, since the memory space is unknown. It is therefore not only necessary to re-enter the code of this new transmitter, but also the codes of all other transmitters, which are therefore still valid. This process is time consuming and not very flexible.

Eine Ausführungsart der Erfindung erlaubt es, dieses Problem zu lösen. Dazu sendet der genannte programmierbare Sender nach Sendung des genannten und vorher festgelegten Festcodes durch den programmierbaren Sender eine laufende Nummer aus, die einem der Register entspricht, und der Empfänger speichert den Steuercode in dem Speicherfach, dem diese laufende Nummer zugeordnet ist.An embodiment of the invention makes it possible to solve this problem. For this purpose, the programmable transmitter mentioned transmits after the transmission of the specified and previously fixed code the programmable transmitter selects a serial number that corresponds to one of the registers, and the receiver stores the control code in the memory compartment to which this serial number is assigned.

Diese laufende Nummer ist somit dem Sender zugeordnet. Bei Verlust dieses Senders genügt es, den Code des Austauschsenders unter Angabe der gleichen laufenden Nummer wie derjenigen, die verlorenging oder zerstört wurde, einzuspeichern. Am Sender kann die laufende Nummer in Form einer Ziffer oder vorzugsweise in Form einer Farbe eingetragen werden. In diesem Falle verfügt der programmierbare Sender über Folgetasten mit unterschiedlichen Farben. Nach Einspeicherung des Codes erhält jeder Sender eine Markierung mit der Farbe der benutzten Taste in Form eines Anstrichs in unverwischbarer Farbe, eines farbigen Etiketts oder eines Stifts aus farbigem Kunststoff, der in eine Öffnung des Empfängers eingesteckt wird.This sequential number is thus assigned to the sender. If this transmitter is lost, it is sufficient to save the code of the replacement transmitter, specifying the same serial number as that which was lost or destroyed. The serial number can be entered on the transmitter in the form of a number or preferably in the form of a color. In this case, the programmable transmitter has sequential buttons with different colors. After the code has been saved, each transmitter receives a marking with the color of the button used in the form of an indelible paint, a colored label or a pen made of colored plastic, which is inserted into an opening of the receiver.
