Moderne Schlüsseleinrichtungen erhalten als zentrales Element einen mit einem Chip gekoppelten Transponder, welcher bei elektromagnetischer Anregung eine Benutzercodeinformation, beispielsweise in Form einer Zahlenfolge, aussendet.Modern key facilities get central Element a transponder coupled to a chip, which with electromagnetic excitation User code information, for example in the form of a Number sequence, sends out.
In der Steuereinrichtung wird dann verglichen, ob die vom Transponder in der Schlüsseleinrichtung ausgesandte Benutzercodeinformation auf einen autorisierten Benutzer schließen läßt oder nicht. Nur bei Identifizierung des autorisierten Benutzers gibt die Steuereinrichtung den Zugang zu den nachgeschalteten Komponenten des Fahrzeuges frei, während im anderen Fall der Zugang zum Betrieb des Fahrzeuges blockiert wird. Um den Besitzer der jeweiligen Schlüsseleinrichtung als autorisiert auszuweisen, wird in einem sogenannten "Anlernprozeß" der Schlüsseleinrichtung ein geheimer Code von der Steuereinrichtung übertragen. Nach dem Anlernen des kompletten Fahrzeugschlüsselsatzes, der dem Benutzer bei der Übernahme des Fahrzeuges übergeben wurde, ist jeder Schlüssel somit kennzeichnend für den autorisierten Fahrzeugbenutzer.The control device then compares whether the Transponder sent out in the key device User code information to an authorized user lets close or not. Only if the authorized user, the control device gives the Access to the downstream components of the vehicle free, while in the other case access to the operation of the Vehicle is blocked. To the owner of each Identifying the key device as authorized is described in a so-called "learning process" of the key device transmit a secret code from the control device. After teaching the complete set of vehicle keys, of the user when he takes over the vehicle each key is therefore characteristic for the authorized vehicle user.

Es entsteht jedoch immer wieder ein Bedarf nach weiteren Schlüsseleinrichtungen und damit nach einem nachträglichen Anlernen von Schlüsseleinrichtungen, beispielsweise im Fall eines Verlustes oder für zusätzliche Benutzer eines Fahrzeuges. Im allgemeinen ist es hierfür erforderlich, die Steuereinrichtung durch Mitteilung eines Benutzercodes (PIN) für diese Prozedur freizuschalten. Dies geschieht üblicherweise mit Hilfe eines Werkstatt-/Diagnosetesters o.ä. in einer mehr oder weniger aufwendigen Verfahrensweise.However, there is always a need for more Key facilities and thus after one subsequent teaching of key facilities, for example in the event of a loss or for additional users of a vehicle. Generally is it is necessary for this to happen through the control device Notification of a user code (PIN) for this procedure unlock. This is usually done with the help a workshop / diagnostic tester or similar in a more or less complex procedure.

Mit den Mitteln der Erfindung kann in einer Ersatzteilzentrale ein angeforderter Ersatzschlüssel mit einer Freigabeinformation vorprogrammiert werden. Die Schlüsseleinrichtung wird dem anfordernden Fahrzeugbenutzer anschließend direkt zur Verfügung gestellt. Dieser kann dann die neue Schlüsseleinrichtung ohne besondere Hilfsmittel oder -prozeduren und ohne Hilfspersonal automatisch an die Steuereinrichtung anlernen lassen. Auf diese Weise läßt sich eine erhöhte Servicefreundlichkeit realisieren. Insbesondere in Regionen mit dünnem Händlernetz oder bei Schlüsselverlust im Urlaub ist somit die Verwendung der erfindungsgemäßen Vorrichtung von Vorteil.With the means of the invention can in one Spare parts center with a requested replacement key release information can be preprogrammed. The Key facility will be the requestor Vehicle users are then immediately available posed. This can then be the new key device without special aids or procedures and without Auxiliary staff automatically to the control device let learn. In this way, an increased Realize service friendliness. Especially in Regions with a thin dealer network or where keys are lost is on vacation the use of the invention Device advantageous.

Desweiteren ist eine Einrichtung C einer Ersatzteilzentrale dargestellt, die unter anderem eine Datenbank enthält oder aber Zugriff auf eine solche hat. Die Datenbank beinhaltet Speicherbereiche SC1-SCn, in denen fahrzeugspezifische Informationen von allen Fahrzeugen, für die diese Ersatzteilzentrale zuständig ist, gespeichert sind. Hier sei angenommen, daß es sich um gesonderte geheime Informationen handelt. Alternativ können aber auch offen zugängliche Informationen wie die Steuergeräteidentifikationsnummern gespeichert sein. Die Einrichtung C der Ersatzteilzentrale verfügt außerdem über (nicht dargestellte) Mittel zum Übertragen der gespeicherten geheimen Daten oder, im Fall von nicht geheimen gespeicherten Daten, über Mittel zum Verschlüsseln und Übertragen der Daten.Furthermore, a device C of a spare parts center is shown, which among other things contains a database or has access to one. The database contains storage areas SC 1 -SC n , in which vehicle-specific information of all vehicles for which this spare parts center is responsible is stored. Here it is assumed that it is separate secret information. Alternatively, however, openly accessible information such as the control unit identification numbers can also be stored. The device C of the spare parts center also has means (not shown) for transmitting the stored secret data or, in the case of non-secret stored data, means for encrypting and transmitting the data.
Die Ersatzteilzentrale erhält von einem Kunden die Anfrage nach einer weiteren Schlüsseleinrichtung für ein Fahrzeug. In einem ersten Schritt ermittelt die Einrichtung C der Ersatzteilzentrale, welche gespeicherte Information zu dem Fahrzeug gehört, für das eine neue Schlüsseleinrichtung angefordert wird. Anschließend überträgt die Einrichtung C diese oder eine daraus generierte Freigabeinformation M2 an eine Schlüsseleinrichtung B, die bislang noch keinem Fahrzeug zugeordnet ist und deren zwei Speicherbereiche SP1 und SP2 noch keine Daten beinhalten.The spare parts center receives the from a customer Request for another key facility for a Vehicle. In a first step, the Device C of the spare parts center, which saved Information belongs to the vehicle for which a new one Key facility is requested. Subsequently device C transmits this or one of them generated release information M2 to a Key device B, which has not yet been a vehicle is assigned and the two memory areas SP1 and SP2 does not yet contain any data.
Die Schlüsseleinrichtung B speichert die empfangene Freigabeinformation M2 in seinem zusätzlichen Speicherbereich SP2. Die Schlüsseleinrichtung B, die in der zweiten Darstellung (2) nochmals mit mit der Information M2 belegtem Speicherbereich SP2 gezeigt ist, kann nun von der Ersatzteilzentrale an den Kunden übergeben werden.The key device B stores the received one Release information M2 in its additional Memory area SP2. The key device B, which in the second representation (2) again with the Information M2 occupied memory area SP2 is shown, can now be sent from the spare parts center to the customer be handed over.
In der dritten Darstellung (3) wird wiederum die oben beschriebene Schlüsseleinrichtung B gezeigt. Zusätzlich ist hier durch ein Rechteck ein Fahrzeug FZ angedeutet, an dessen Steuereinheit die neue Schlüsseleinrichtung B angelernt werden soll. Diese Steuereinheit ist in dem Fahrzeug FZ eingezeichnet und mit A bezeichnet. Die Steuereinheit A verfügt über mindestens einen Speicherbereich SP3, in dem der geheime Code zur Prüfung der Nutzungsberechtigung abgelegt ist. Desweiteren verfügt sie über ein Vergleichsmittel V und über nicht eingezeichnete Mittel zur Übertragung von Daten. Für das Ausführungsbeispiel ist ein zweiter Speicherbereich SP4 vorgesehen, in dem eine weitere geheime Information abgelegt ist. Zusätzlich oder alternativ kann ein Speicherbereich für das Speichern einer PIN-Nummer vorhanden sein.In the third representation (3) the above is again described key device B shown. In addition a vehicle FZ is indicated here by a rectangle, at its control unit the new key device B should be taught. This control unit is in the Vehicle FZ shown and labeled A. The Control unit A has at least one Memory area SP3, in which the secret code for checking the usage authorization has been filed. Furthermore it has a comparison means V and not indicated means for the transmission of data. For the The exemplary embodiment is a second memory area SP4 provided in which another secret information is filed. Additionally or alternatively, a Storage area for storing a PIN number to be available.
Die Schlüsseleinrichtung B, die dem Kunden von der Ersatzteilzentrale ausgehändigt wurde und die nun über eine geheime Freigabeinformation M2 verfügt, liest diese Information aus ihrem zusätzlichen Speicherbereich SP2 aus und überträgt sie, wie durch einen Pfeil angedeutet, an die Steuereinheit A des Fahrzeugs FZ.The key device B, which the customer of the Spare parts center was handed over and now over has a secret release information M2, reads this Information from their additional memory area SP2 and transmits them, as indicated by an arrow, to the control unit A of the vehicle FZ.
Die gleichen Elemente wie in der Darstellung (3) tauchen auch in der Darstellung (4) auf.Dive the same elements as in illustration (3) also in the representation (4).
Die Vergleichsmittel V der Steuereinheit A vergleichen die von der Schlüsseleinrichtung empfangene Freigabeinformation M2 mit einer in dem zusätzlichen Speicherbereich SP4 gespeicherten geheimen Information. Wird eine Übereinstimmung festgestellt, so erfolgt eine Freigabe für das eigentliche "Anlernen" einer neuen Schlüsseleinrichtung B an die Steuereinrichtung A des Fahrzeugs in üblicher Weise. Die Steuereinrichtung A überträgt hierzu den geheimen Code M1 für die Überprüfung der Nutzungsberechtigung automatisch an die Schlüsseleinrichtung B. Compare the comparison means V of the control unit A. the one received by the key device Release information M2 with one in the additional Storage area SP4 stored secret information. If a match is found, there is a match Approval for the actual "learning" of a new one Key device B to the control device A of the Vehicle in the usual way. The control device A for this purpose transmits the secret code M1 for the check of the usage authorization automatically to the Key device B.
Die Schlüsseleinrichtung B speichert den empfangenen geheimen Code M1 in dem ersten Speicherbereich SP1 des Transponders, wie in Darstellung (5) zu sehen.The key device B stores the received one secret code M1 in the first memory area SP1 of the Transponders, as can be seen in illustration (5).
Die Schlüsseleinrichtung B ist jetzt an die Steuereinheit A des Fahrzeugs FZ angelernt und kann von dem Benutzer als Nachweis der Berechtigung der Nutzung des Fahrzeugs verwendet werden.The key device B is now at the control unit A of the vehicle FZ is taught and can by the user as proof of the authorization to use the vehicle be used.
In dem beschriebenen Ausführungsbeispiel wurde ein zusätzlicher Speicherbereich SP4 in der Steuereinheit A vorgesehen, in dem eine der Freigabeinformation in dem zusätzlichen Speicherbereich SP2 der Schlüsseleinrichtung entsprechende Information gespeichert ist. Ein solcher zusätzlicher Speicherbereich stellt jedoch kein notwendiges Element für eine erfindungsgemäße Vorrichtung dar. Beispielsweise kann als geheime Information für die Berechtigung zum Anlernen ebenso die PIN-Nummer verwendet werden, oder aber der geheime Code für die normale Zugangsberechtigung selber. Eine weitere Alternative ist, wie bereits erwähnt, die Verwendung von offen zugänglichen Informationen wie der Steuergeräteidentifikationsnummer, wenn diese zunächst verschlüsselt werden.In the described embodiment, a additional memory area SP4 in control unit A provided in which one of the release information in the additional memory area SP2 of the key device corresponding information is stored. Such a however, no additional memory area necessary element for a device according to the invention For example, as secret information for the Authorization to teach in also uses the PIN number or the secret code for normal Access authorization itself. Another alternative is as mentioned earlier, the use of open accessible information like that ECU identification number, if this first be encrypted.
Hat die Schlüsseleinrichtung B in der Ersatzteilzentrale bereits den geheimen Code M1 erhalten, so kann sie von der Zentrale zusätzlich eine zweite Information M2 empfangen und diese speichern, mit der dann zwischen einer zum automatischen Anlernen berechtigten Schlüsseleinrichtung und einer verlorenen Schlüsseleinrichtung, die besser gesperrt bleibt, unterschieden werden kann.Has the key device B in the spare parts center already received the secret code M1, it can be from the head office additionally a second information M2 received and save it, with which then between one authorized for automatic teaching Key facility and a lost one Key device that remains better locked out can be distinguished.
