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 as central Element a transponder coupled to a chip, which in electromagnetic excitation a 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.In the control device is then compared, whether the from Transponder emitted in the key device User code information to an authorized user close or not. Only with identification of the authorized user gives the controller 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 the respective Key device is to be designated as authorized in a so-called "learning process" of the key device a secret code transmitted by the controller. After teaching the complete vehicle key set, the user when taking over the vehicle has been passed, each key is thus characteristic for the authorized vehicle user.
Vorrichtungen dieser Art sind beispielsweise aus der DE 4317119 C2 und der DE 4435894 A1 bekannt.Devices of this type are known for example from DE 4317119 C2 and DE 4435894 A1.
Aus der DE 4441415 A1 ist ein System zur Erstellung von
Ersatzschlüsseln bekannt. Hierzu ist jedes Fahrzeug mit
einem Fahrzeugidentifizierungs-Code ausgestattet.
Zwischen Ersatzschlüssel und einem Sender innerhalb des
Fahrzeugs werden verschlüsselte Codes ausgetauscht und im
Ersatzschlüssel in einer Datenmatrix abgespeichert. Der
Ersatzschlüssel weist dabei zumindest zwei Speicherplätze
auf, in denen der Fahrzeugidentifizierungs-Code und eine
Entschlüsselungsfunktion gespeichert sein können.From DE 4441415 A1 a system for creating spare keys is known. For this purpose, each vehicle is equipped with a vehicle identification code.
Between spare keys and a transmitter within the vehicle encrypted codes are exchanged and stored in the spare key in a data matrix. The replacement key has at least two memory locations in which the vehicle identification code and a decryption function can be stored.
Ferner ist aus der DE 4441415 A1 bekannt, dass zum Anlernen eines neuen Schlüssels an ein Fahrzeug ein verschlüsselter Code C und ein Befehlscode BC im Schlüssel abgelegt werden. Bei der Erstellung des Ersatzschlüssels wird in einem ersten Speicherabschnitt der verschlüsselte Code C abgelegt und ein einem zweiten Speicherabschnitt der Befehlscode BC. Zum Anlernen sendet der Ersatzschlüssel den verschlüsselten Code C zusammen mit dem Befehlscode BC an das Fahrzeug. Im Fahrzeug wird der Code C ermittelt und aus dem Code C wird die Fahrgestellnummer ermittelt. Diese Fahrgestellnummer wird mit einer in dem Fahrzeug gespeicherten Fahrgestellnummer verglichen.Furthermore, it is known from DE 4441415 A1 that the Teaching a new key to a vehicle encrypted code C and a command code BC in Key are stored. When creating the Spare key is in a first memory section the encrypted code C is stored and a second Memory section of the command code BC. Sends for learning the spare key is the encrypted code C together with the command code BC to the vehicle. In the vehicle will the code C is determined and from the code C is the Chassis number determined. This VIN will be with a VIN stored in the vehicle compared.
Bei Übereinstimmung wird der Befehlscode BC ausgelesen und beim Vorliegend eines Anlernbefehls mit einer Freigaberoutine fortgesetzt. Zum Anlernen wird mit Hilfe eines Zufallsgenerators ein Zufallscode erzeugt. Der Zufallscode wird an das Fahrzeug übermittelt und dort wird der Code C, der die Fahrgestellnummer VIN enthält, überschrieben. Das bedeutet, dass der von der Werkstatt eingespeicherte geheime Code C nach dem Anlernen in dem Schlüssel überschrieben wird und nicht mehr vorhanden ist. If they match, the instruction code BC is read out and in the presence of a teach-in command with a Sharing routine continued. To learn with help a random number generator generates a random code. Of the Random code is transmitted to the vehicle and there is the code C, which contains the VIN, overwritten. That means that of the workshop stored secret code C after learning in the Key is overwritten and no longer exists is.
Die US 5,369,706 betrifft ein Verfahren zum Freigeben einer Zugangskontrolleinrichtung mittels rollierender Codes. Bei rollierenden Codes werden beispielsweise aus Hash-Tabellen Geheimcodes entnommen, die zum einmaligen Freischalten einer Zugangskontrolleinrichtung berechtigen. Danach, dass heißt nach einmaligen Freischalten, wird ein neuer Code ermittelt. Diese rollierenden Codes (Hash-Tabellen) sind sowohl im Schloss als auch im Schlüssel gespeichert. Daher wird, wenn im Schlüssel der nächste Code ermittelt wird, dieser auch im Schloss ermittelt. Da die Hash-Tabellen von außen nicht einsehbar sind, ist somit eine sichere Zugangskontrolle möglich.US 5,369,706 relates to a method for releasing an access control device by means of rolling Codes. For example, rolling codes will look like Hash tables are taken from secret codes that are unique Activation of an access control device entitle. After that, that is after one-time Unlock, a new code is detected. These rolling codes (hash tables) are both in the lock as well as stored in the key. Therefore, when in the Key the next code is detected, this one also in the Lock detected. Since the hash tables are not from the outside is therefore a secure access control possible.
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 training of key facilities, for example, in the case of loss or for additional users of a vehicle.

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 to the control unit A of the vehicle FZ taught and can by the user as proof of 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 was a additional memory area SP4 in the 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, there is no additional memory area necessary element for a device according to the invention For example, as secret information for the Authorization to teach as well as the PIN number used or the secret code for the normal one Access authorization itself. Another alternative is As already mentioned, the use of open accessible information like the 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 from the headquarters additionally a second information M2 receive and save this, then between one authorized for automatic training Key facility and a lost one Key device that remains better locked, can be distinguished.
