Vorteile der ErfindungAdvantages of the invention

Mit den Maßnahmen des Anspruchs 1, d.h. mit einem Fahrzeugschlüssel mit aufnehmbarer Signatur, wobei der Fahrzeugschlüssel eingerichtet ist mehrere Signaturen veränderbar für unterschiedliche Fahrzeuge aufzunehmen, d.h. einem System zur Aktivierung eines Fahrzeugschlüssels, wobei ein Programmiergerät vorgesehen ist, welches die vom Fahrzeughersteller gelieferten fahrzeugindividuellen Signaturen bereithält und wobei das Progammiergerät eingerichtet ist, mehrere Signaturen für unterschiedliche Fahrzeuge auf mindestens einen Fahrzeugschlüssel zu übertragen, ist es möglich, mit einem Schlüssel mehrere Fahrzeuge freizuschalten oder zu sperren, auch für mehrere Fahrzeuge gleichzeitig. Auch das Freischalten von mehreren Schlüsseln für ein Fahrzeug ist möglich.With the measures of claim 1, ie with a vehicle key with recordable signature, wherein the vehicle key is adapted to accommodate a plurality of signatures changeable for different vehicles, ie a system for activating a vehicle key, wherein a programming device is provided which holds the vehicle-specific signatures supplied by the vehicle manufacturer and wherein the programming device is adapted to transmit multiple signatures for different vehicles on at least one vehicle key, it is possible with a Key to unlock or lock multiple vehicles, even for multiple vehicles at the same time. It is also possible to unlock several keys for a vehicle.

Die Erfindung erleichtert die Verwaltung von Fahrzeugschlüsseln bei Taxi-, Bus- oder Transportunternehmen, insbesondere mit einem größeren Fuhrpark. Jeder ihrer Fahrer erhält einen Schlüssel, der für bestimmte Fahrzeuge freigeschaltet ist, die der Fahrer nutzen darf. So kann ein Fahrer jedes der ihm zugewiesenen Fahrzeuge bewegen, ohne einen individuellen Schlüssel für dieses suchen zu müssen.The invention facilitates the management of vehicle keys in taxi, bus or transport companies, especially with a larger fleet. Each of their drivers receives a key that is unlocked for certain vehicles that the driver is allowed to use. Thus, a driver can move any of his assigned vehicles without having to search for an individual key for this.

In den Unteransprüchen sind vorteilhafte Ausgestaltungen des Fahrzeugsschlüssels bzw. des Systems aufgezeigt.In the subclaims advantageous embodiments of the vehicle key or the system are shown.

Zeichnungdrawing

Anhand der Figur 1, die ein Blockschaltbild für die Erfindung zeigt, werden Ausführungsbeispiele erläutert.Based on FIG. 1 , which shows a block diagram of the invention, embodiments will be explained.

Beschreibung von AusführungsbeispielenDescription of exemplary embodiments

Ein elektronischer Fahrzeugschlüssel 1 nach der Erfindung zeichnet sich dadurch aus, dass er eingerichtet ist, mehrere Signaturen für unterschiedliche Fahrzeuge aufzunehmen, wobei mindestens eine der Signaturen auch veränderbar sein soll. Zur Übertragung und Veränderung der Signatur auf den Fahrzeugschlüssel 1 ist ein Programmiergerät 2 vorgesehen. Die Fahrzeugschlüssel gleichen den üblichen Schlüsseln von Fahrzeugen mit Wegfahrsperre. Jedes Fahrzeug erwartet von einem Fahrzeugschlüssel eine eindeutige Signatur, um die Wegfahrsperre zu deaktivieren und die Nutzung des Fahrzeuges zuzulassen. Die fahrzeugindividuellen Signaturen der freischaltbaren Fahrzeuge werden durch den Fahrzeughersteller, beziehungsweise eine Signaturvergabestelle 3 auf das Programmiergerät 2 übertragen.An electronic vehicle key 1 according to the invention is characterized in that it is adapted to receive a plurality of signatures for different vehicles, wherein at least one of the signatures should also be changeable. For transmission and modification of the signature on the vehicle key 1, a programming device 2 is provided. The vehicle keys are similar to the usual keys of vehicles with immobilizer. Each vehicle expects from a vehicle key a unique signature to disable the immobilizer and allow the use of the vehicle. The vehicle-specific signatures of the unlockable vehicles are transmitted to the programming device 2 by the vehicle manufacturer, or a signature assignment point 3.

Zur Zuweisung von Fahrzeugen zu einem Nutzer werden die Signaturen der Fahrzeuge mittels des Programmiergeräts 2 auf seinen Schlüssel übertragen. Zur Aufnahme von mindestens zwei Signaturen ist im Fahrzeugschlüssel 1 ein programmierbarer Chip 4 mit Speicher vorgesehen. Jede programmierte Zuweisung kann mit einem Gültigkeitszeitraum verknüpft werden, in welchem der Nutzer das beziehungsweise die Fahrzeuge benutzen darf. Die Gültigkeitszeiträume der einzelnen Signaturen können auch unterschiedlich sein und sich teilweise überlappen oder auch nicht. Außerhalb des jeweils zugewiesenen Gültigkeitszeitraumes kann das Fahrzeug mit dem Fahrzeugschlüssel nicht genutzt werden.In order to assign vehicles to a user, the signatures of the vehicles are transmitted by means of the programmer 2 to his key. To record at least two signatures in the vehicle key 1, a programmable chip 4 with Memory provided. Each programmed assignment can be linked to a validity period in which the user may use the vehicle (s). The validity periods of the individual signatures can also be different and partially overlap or not. Outside the respectively assigned validity period, the vehicle can not be used with the vehicle key.

Das Fahrzeug prüft beim Aufschließen beziehungsweise beim Starten nur, ob der Schlüssel die zum Fahrzeug passende Signatur enthält.When unlocking or when starting, the vehicle only checks whether the key contains the appropriate signature for the vehicle.

Abhängig von der Ausgestaltung der Wegfahrsperre im Fahrzeug ist es möglich, den Fahrzeugschlüssel derart zu gestalten, dass am Fahrzeug selbst keine Modifikationen notwendig sind.Depending on the configuration of the immobilizer in the vehicle, it is possible to design the vehicle key such that no modifications to the vehicle itself are necessary.

Das Programmiergerät kann auch in einer Weiterbildung der Erfindung so ausgestaltet sein, dass sich der Bediener als zur Schlüsselaktivierung Berechtigter identifizieren muss, um eine missbräuchliche Benutzung zu unterbinden. Auch kann das Programmiergerät 2 so ausgebildet sein, dass der Schlüssel 1 in vereinbarten Zeitabständen vom Programmiergerät 2 zu prüfen ist oder von diesem über eine Funkschnittstelle 5 gesperrt werden kann, z.B. bei missbräuchlicher Benutzung oder Diebstahl des Fahrzeugs. Auch kann vorgesehen werden, den Fahrzeugschlüssel mit einer Funkschnittstelle für eine Trailerbox auszustatten. Über die Trailerbox und die Funkschnittstelle 5 des Fahrzeugschlüssels kann dann z.B. eine Fuhrparkzentrale oder die Polizei auch bei größeren Entfernungen direkt in die Schlüsselaktivierung eingreifen und den Schlüssel für eine erneute Benutzung sperren beziehungsweise die Signatur/en zu deaktivieren.The programming device can also be configured in a development of the invention so that the operator must identify himself as authorized to activate the key in order to prevent improper use. The programming device 2 can also be designed so that the key 1 can be checked by the programming device 2 at agreed intervals or can be blocked by the programming device 2, for example by means of a radio interface 5, e.g. in case of misuse or theft of the vehicle. It can also be provided to equip the vehicle key with a radio interface for a trailer box. Via the trailer box and the radio interface 5 of the vehicle key, it is then possible, e.g. a fleet center or the police intervene even in larger distances directly into the key activation and lock the key for reuse or disable the signature / s.
