Description

Die Erfindung betrifft einen Schlüssel gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a key according to the preamble of patent claim 1.

Betrachtet man den bevorzugten Einsatzfall der Erfindung, nämlich bei Kraftfahrzeugen, so besteht häufig Interesse daran, beispielsweise beim Werkstattaufenthalt des Fahrzeugs oder bei Benutzung des Fahrzeugs durch andere Personen (z.B. Service-Personal in Hotels) den Zugang zum Handschuhfach oder zum Gepäckabteil unmöglich zu machen. Eine bekannte Lösung dieser Aufgabe sieht das Vorhandensein von zwei Schlüsseln vor, von denen einer als Hauptschlüssel für alle erforderlichen Schließfunktionen eingerichtet ist, während ein besonderer Park- oder Werkstattschlüssel nur solche Schließfunktionen ausübt bzw. einleitet, die zum Fahren des Fahrzeugs unbedingt erforderlich sind, also beispielsweise Schließfunktionen im Rahmen der Türschlösser und eines Zündschlosses.If one considers the preferred application of the invention, namely in motor vehicles, there is often interest in this, for example when the Vehicle or when the vehicle is used by other people (e.g. service personnel in hotels) access to the glove compartment or luggage compartment is impossible close. A known solution to this problem is the presence of two Keys, one of which is required as a master key for all Locking functions is set up during a special parking or Workshop key only performs or initiates locking functions that drive of the vehicle are absolutely necessary, for example locking functions in the Frame of the door locks and an ignition lock.

Diese an sich technisch befriedigende Lösung hat aber den bedienungsmäßigen Nachteil, daß stets zwei Schlüssel mitgeführt werden müssen. Hinzu kommt insbesondere bei modernen elektronischen Schließsystemen der bei beiden Schlüsseln zu treibende Aufwand an elektronischen Einrichtungen.This technically satisfactory solution, however, has the operational one Disadvantage that two keys must always be carried. Come in addition especially with modern electronic locking systems with both keys Electronic equipment effort to be driven.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Schlüssel zu schaffen, der ohne den Aufwand eines zusätzlichen Werkstattschlüssels eine zeitweilige Reduzierung der Zahl der Schließfunktionen vorzunehmen gestattet.The invention has for its object to a generic key create a temporary one without the effort of an additional workshop key Reduction of the number of locking functions allowed.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausführungen der Erfindung beschreiben die Unteransprüche. The inventive solution to this problem consists in the characterizing Features of the main claim describe advantageous embodiments of the invention the subclaims.

Im normalen Betrieb des Fahrzeugs - um bei dem bevorzugten Ausführungsbeispiel zu bleiben - wird der Schlüssel also aus zumindest zwei Schlüsselteilen gebildet, und die Schlüsselteile sind so ausgelegt, daß der Schlüssel nur in diesem zusammengesetzten Zustand alle elektronischen Schließfunktionen ausüben kann, sonst aber nur den Fahrbetrieb ermöglicht.In normal operation of the vehicle - in the preferred embodiment too remain - so the key is made up of at least two key parts, and that Key parts are designed so that the key is assembled only in this State can perform all electronic locking functions, but otherwise only the Operation possible.

Grundsätzlich wäre es möglich, die beiden Schlüsselteile jeweils als für unterschiedliche elektronische Schließtunktionen ausgelegte komplette Schlüssel auszubilden, die lediglich zur mechanischen Kopplung eingerichtet sind. Dies würde aber insbesondere bei modernen Schließsystemen, die von einem Schlüssel drahtlos übertragene Befehle nach Überprüfung in Betätigungssignale umsetzen, einen mehrfachen Aufwand an elektronischen Einrichtungen in den verschiedenen Schlüsselteilen erfordern. Günstiger ist daher eine solche Ausbildung der verschiedenen Schlüsselteile, daß ein gleichsam einen Hauptschlüssel bildender Schlüsselteil durch Integration des zumindest einen weiteren Schlüsselteils lediglich um eine elektronische Identifikation ergänzt wird, die einer Auswerteschaltung im Fahrzeug signalisiert, daß von dem Hauptschlüssel gegebene Befehle für sonst unterdrückte Schließfunktionen des Hauptschlüssels ausgeführt werden sollen. Wenn auch bei dieser bevorzugten Ausführungsform der Erfindung der weitere Schlüsselteil im Rahmen der bisherigen Betrachtung keinen kompletten Schlüssel darstellt, sondern funktionsmäßig lediglich eine Identifikation beinhaltet, ist es doch möglich, beispielsweise in einen Bart dieses weiteren Schlüsselteils bestimmte Schließfunktionen zu integrieren, so daß dieser Schlüsselteil gleichsam einen Ersatzschlüssel bildet.In principle, it would be possible to use the two key parts as different ones to design complete locking keys designed for electronic locking functions are only set up for mechanical coupling. But this would in particular in modern locking systems, the commands transmitted wirelessly by a key convert into actuation signals after checking, a multiple effort require electronic facilities in the various key parts. Cheaper is therefore such a training of the various key parts that one as it were a key part forming a master key by integrating the at least one Another key part is only supplemented by an electronic identification that an evaluation circuit in the vehicle signals that from the master key given commands for otherwise suppressed locking functions of the master key to be executed. Although in this preferred embodiment the Invention of the further key part in the context of the previous consideration none represents complete key, but functionally just an identification includes, it is possible, for example, in a beard of this further Key part to integrate certain locking functions, so that this key part as it were a replacement key.

Ein Ausführungsbeispiel der Erfindung für den bevorzugten Einsatzfall, also bei einem Kraftfahrzeug, wird im folgenden anhand der Zeichnung erläutert, deren Figuren perspektivisch den Schlüssel in verschiedenen Zuständen wiedergeben.An embodiment of the invention for the preferred application, that is in one Motor vehicle, is explained below with reference to the drawing, the figures Perspectively play the key in different states.

Betrachtet man zunächst Figur 1, so erkennt man bei 1 den eine Schiebeaufnahme für den weiteren Schlüsselteil 2 bildenden ersten Schlüsselteil; von dem weiteren Schlüsselteil 2, der in der Darstellung der Figur 1 parallel zur Zeichenebene von rechts nach links in die Aufnahme des Schlüsselteils 1 hineingeschoben ist, erkennt man lediglich einen Bereich der Handhabe 3, der aus der Aufnahme herausragt. An die Handhabe 3 schließt sich in der Darstellung in Richtung nach links der in den Figuren 2 und 3 erkennbare Schlüsselbart 4 an, der also den in der normalen Betriebsstellung, d.h. während des normalen Fahrbetriebs, in die Schiebeaufnahme des Schlüsselteils 1 hineingeschobenen Bestandteil des weiteren Schlüsselteils 2 bildet. Dieser kann beispielsweise durch federnde Rasten, wie sie jedem Fachmann bekannt sind, in der Aufnahme 5 (siehe Figur 3) des ersten Schlüsselteils 1 durch Aufbringen einer Kraft lösbar arretiert sein.If one first looks at FIG. 1, one can see at 1 that a sliding mount for the first key part forming the further key part 2; from the further Key part 2, which is parallel to the drawing plane from the right in the illustration of FIG is pushed into the receptacle of the key part 1 to the left, can be seen only an area of the handle 3 that protrudes from the receptacle. To the Handle 3 closes in the illustration in the direction to the left of that in FIGS. 2 and 3 recognizable key bit 4, which is the one in the normal operating position, i.e. during normal driving, in the sliding holder of the key part 1 inserted part of the further key part 2 forms. This can for example by resilient catches, as are known to any person skilled in the art Recording 5 (see Figure 3) of the first key part 1 by applying a force be releasably locked.

In Figur 2 ist nun der Zustand des Schlüssels dargestellt, bei dem beispielsweise während eines Werkstattbesuchs des Fahrzeugs die Zahl der Schließfunktionen des Schlüssels reduziert ist, beispielsweise auf Schließfunktionen, wie sie zum reinen Fahrbetrieb erforderlich sind. Der Schlüsselteil 1 gibt zwar drahtlose Schließ- bzw. Entriegelungsbefehle an eine Auswerteelektronik in einem fahrzeugseitigen Schließsystem ab, jedoch fehlen bei der in Figur 2 angenommenen Trennung der beiden Schlüsselteile 1 und 2 Identifikationssignale, die von einer im Schlüsselteil 2 untergebrachten Sendeeinrichtung ausgesandt werden. Ist also die Auswerteelektronik im Fahrzeug so ausgebildet, daß sie für bestimmte Schließfunktionen von dem Schlüsselteil 1 ausgesandte Befehle nur dann wirksam werden läßt, wenn zuvor ein Identifikationssignal von dem Schlüsselteil 2 empfangen worden ist, so können nur diejenigen Befehle des Schlüsselteils 1 im Fahrzeug ausgeführt werden, die den reinen Fahrbetrieb ermöglichen; das Öffnen beispielsweise eines Handschuhfachdeckels oder der Haube eines Kofferraums ist unmöglich. Erst wenn durch mechanische Vereinigung der beiden Schlüsselteile 1 und 2 gemäß Figur 1 der komplette Schlüssel vorliegt, bietet er die Möglichkeit, alle Schließfunktionen auszuüben.In Figure 2, the state of the key is shown, for example the number of locking functions of the Key is reduced, for example to locking functions, such as the pure Driving operations are required. The key part 1 gives wireless locking or Unlocking commands to an evaluation electronics in a vehicle side Locking system from, but missing in the separation of the two assumed in Figure 2 Key parts 1 and 2 identification signals from one in key part 2 housed transmission device can be sent. So is the evaluation electronics trained in the vehicle so that it for certain locking functions of the Key part 1 sent commands can only take effect if a previously Identification signal has been received by the key part 2, so can only those commands of the key part 1 are executed in the vehicle that the pure Enable driving; for example opening a glove box cover or the hood of a trunk is impossible. Only when through mechanical union of the two key parts 1 and 2 according to FIG. 1, the complete key is available he the opportunity to perform all locking functions.

In dem figürlich dargestellten Ausführungsbeispiel bildet der weitere Schlüsselteil 2 dadurch auch einen echten mechanischen Schlüssel, daß in seinen Bart 4, wie bei 6 in Figur 2 angedeutet, ein mechanischer Ersatzschlüssel eingearbeitet ist, der beispielsweise zum Betätigen der Türschlösser und eines Zündschlosses unabhängig von dem ersten Schlüsselteil 1 dient.In the exemplary embodiment shown in the figure, the further key part 2 thereby also a real mechanical key that in his beard 4, as in 6 in Figure 2 indicated, a mechanical replacement key is incorporated, the for example to operate the door locks and an ignition lock independently serves from the first key part 1.

Mit der Erfindung ist demgemäß ein gattungsgemäßer Schlüssel geschaffen, der mit minimalem Aufwand bei hoher Bedienungsfreundlichkeit (es braucht nur ein Schlüssel mitgeführt zu werden) die Möglichkeit gibt, bei Bedarf die Anzahl seiner elektronischen Schließfunktionen zu reduzieren. Wenn bei der Beschreibung der Erfindung stets Bezug genommen wurde auf die Verhältnisse bei einem Kraftfahrzeug, schließt dies den Einsatz der Erfindung in anderen Einsatzfällen doch nicht aus. Beispielsweise kann es sich um einen Schlüssel handeln, der sowohl zum Öffnen von Räumen als auch von Behältnissen in diesen eingerichtet ist, wobei aber auch die Möglichkeit gegeben sein soll, nur die zum Öffnen der Räume erforderlichen Schließfunktionen zu aktivieren, dagegen die zum Öffnen der Behältnisse erforderlichen Schließfunktionen zeitweilig zu unterdrücken.With the invention, a generic key is accordingly created, which with minimal effort with ease of use (only one key is required to be carried) gives the opportunity, if necessary, the number of its electronic Reduce locking functions. When always referring to the description of the invention was taken on the conditions of a motor vehicle, this excludes the Use of the invention in other applications is not enough. For example, it can is a key that is used to open rooms as well as Containers is set up in these, but there is also the possibility should only activate the locking functions required to open the rooms, on the other hand, the locking functions required to open the containers temporarily increase suppress.
