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 (DE 44 09 559 A1).Considering the preferred application of the invention, namely in motor vehicles, there is often an interest in making access to the glove box or luggage compartment impossible, for example, during the workshop visit of the vehicle or when the vehicle is used by other persons (for example service personnel in hotels). A known solution to this problem provides for the presence of two keys, one of which is set up as a master key for all required locking functions, while a particular parking or workshop key exercises only such closing functions that are essential for driving the vehicle, ie For example, closing functions in the context of door locks and an ignition lock (DE 44 09 559 A1).

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.However, this technically satisfactory solution has the operational disadvantage that always two keys must be carried. In addition, especially in modern electronic locking systems of both keys to be driven expenditure on electronic devices.

Mit der DE 39 00 494 A1 wird des Weiteren eine Sicherheitseinrichtung für Kraftfahrzeuge mit einem elektronischen respektive automatischen Schlüssel vorgeschlagen, dessen zentrale Funktion im Aussenden eines aus zwei Anteilen bestehenden Codesignals besteht, wobei der eine Anteil zum Bedienen einer Diebstahlschutzeinrichtung und der andere Anteil zum benutzerindividuellen Einstellen von Bedien- und Benutzerelementen des Kraftfahrzeugs dient. Eine räumliche Trennung von wenigstens zwei Teilschlüsseln mit unterschiedlichen Schließfunktionen ist jedoch nicht vorgesehen.DE 39 00 494 A1 further proposes a safety device for motor vehicles with an electronic or automatic key, the central function of which is to emit a code signal consisting of two parts, one part for operating an anti-theft device and the other for setting the user individually of operating and user elements of the motor vehicle is used. However, a spatial separation of at least two subkeys with different closing functions is not provided.

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. Ferner ist es Aufgabe der Erfindung, den zu treibenden Aufwand an elektronischen Einrichtungen zu minimieren.The invention has for its object to provide a generic key that allows to make a temporary reduction in the number of locking functions without the expense of an additional workshop key. It is another object of the invention to minimize the effort to be driven on electronic devices.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausführungen der Erfindung beschreiben die Unteransprüche.The achievement of this task is the characterizing features of the main claim, advantageous embodiments of the invention describe the dependent claims.

Im normalen Betrieb des Fahrzeugs - um bei dem bevorzugten Ausführungsbeispiel zu bleiben - wird der Schlüssel bekanntermaßen 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.During normal operation of the vehicle - to remain in the preferred embodiment - the key is known to be formed of at least two key parts, and the key parts are designed so that the key can perform all electronic locking functions only in this assembled state, but otherwise only driving allows.

Grundsätzlich wäre es möglich, wie bereits oben beschrieben (DE 44 09 559 A1), die beiden Schlüsselteile jeweils als für unterschiedliche elektronische Schließfunktionen 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.In principle, it would be possible, as already described above (DE 44 09 559 A1), to design the two key parts in each case as complete keys designed for different electronic locking functions, which are set up only for mechanical coupling. However, this would require a multiple cost of electronic devices in the various key parts, especially in modern locking systems that implement wirelessly transmitted commands from a key after verification in actuation signals.

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.Cheaper is therefore such a design of the various key parts that as it were a master key forming key part is supplemented by integration of at least one other key part only to an electronic identification that signals an evaluation circuit in the vehicle that given by the master key commands for otherwise suppressed locking functions of Main key to be executed. Although in this preferred embodiment of the invention, the further key part in the context of previous consideration is not a complete key, but functionally includes only one identification, it is still possible to integrate certain locking functions, for example, in a beard of this further key part, so that this key part as it were forms a spare 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, ie in a motor vehicle, will be explained below with reference to the drawing, the figures represent in perspective 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 recognizes at 1 the first key part forming a slide receptacle for the further key part 2; from the other key part 2, which is in the representation of Figure 1 is pushed parallel to the plane of the right to left in the receptacle of the key part 1, one recognizes only a portion of the handle 3, which protrudes from the receptacle. At the handle 3 joins in the representation in the direction of the left of the recognizable in Figures 2 and 3 key bit 4, so that in the normal operating position, ie during normal driving, forms in the sliding receptacle of the key part 1 inserted part of the further key part 2. This can be releasably locked, for example by resilient detents, as they are known to those skilled in the receptacle 5 (see Figure 3) of the first key part 1 by applying a force.

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, in which, for example, during a workshop visit to the vehicle, the number of locking functions of the key is reduced, for example, on the closing functions, as they are required for pure driving. Although the key part 1 gives wireless locking or unlocking commands to an evaluation electronics in a vehicle-side locking system, but missing in the assumed in Figure 2 separation of the two key parts 1 and 2 identification signals that are emitted by a accommodated in the key part 2 transmitting device. Thus, if the transmitter in the vehicle is designed so that it can be effective for certain locking functions of the key part 1 commands only if previously an identification signal has been received from the key part 2, so only those commands of the key part 1 can be performed in the vehicle that enable pure driving; opening, for example, a glove box lid or the hood of a trunk is impossible. Only when the complete key is present by mechanical combination of the two key parts 1 and 2 according to FIG. 1 does it offer the possibility of exercising 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 illustrated embodiment, the further key part 2 thereby also forms a genuine mechanical key that in his beard 4, as indicated at 6 in Figure 2, a mechanical spare key is incorporated, for example, for actuating the door locks and an ignition independently of the first Key part 1 is used.

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 thus created, with minimal effort with high ease of use (it only needs to be carried a key) gives the opportunity to reduce the number of its electronic locking functions if necessary. If reference has always been made in the description of the invention to the conditions in a motor vehicle, this does not exclude the use of the invention in other applications. For example, it can be a key that is set up for both opening of rooms and containers in this, but also to be given the opportunity to activate only required to open the rooms locking functions, however, the time required to open the containers locking functions to suppress.
