Abstract

Schlüssel zum kontaktlosen Ver- und Entriegeln eines Fahrzeugs mit einem Gehäuse für zumindest eine elektrische oder elektronische Schaltung, dadurch gekennzeichnet, dass die Gehäuseform durch elektrisch oder elektronisch gesteuerte Betätigung veränderbar ausgebildet ist.Key for contactless locking and unlocking of a vehicle with a housing for at least one electrical or electronic circuit, characterized in that the housing shape is designed to be changeable by electrically or electronically controlled actuation.

Description

Fahrzeuge werden zunehmend mittels elektronischer Schlüssel über eine Funkstrecke ver- und entriegelt. Dabei wird eine Information über die Funkstrecke mittels eines elektromagnetischen Signals, das alle Frequenzen - auch im Infrarotbereich - umfassen kann, vom Fahrzeug zum Schlüssel und umgekehrt übertragen. Meist ist zum Verriegeln oder Entriegeln ein Taster oder Knopf am Schlüssel zu betätigen. Allerdings kann es insbesondere beim Verriegeln des Fahrzeugs geschehen, dass entweder das Signal nicht korrekt übertragen wird und folglich das Fahrzeug nicht verriegelt wird, oder dass versehentlich der Taster oder der Knopf zweimal gedrückt wird und damit das Fahrzeug zwar verriegelt war aber wieder entriegelt wurde.Vehicles are increasingly locked and unlocked using electronic keys over a radio link. Information is transmitted via the radio link from the vehicle to the key and vice versa by means of an electromagnetic signal, which can include all frequencies - including in the infrared range. Usually a button or button on the key has to be pressed to lock or unlock. However, especially when locking the vehicle, it can happen that either the signal is not transmitted correctly and consequently the vehicle is not locked, or that the button or button is accidentally pressed twice and the vehicle was locked but was unlocked again.

Aus DE 103 39 293 A1 sind Verfahren bekannt, die optische oder akustische Signale vorsehen, die angeben, dass das Fahrzeug nicht verriegelt ist. Allerdings kann dies durch Umgebungsgeräusche oder Unaufmerksamkeit unbemerkt bleiben. DE 103 39 293 A1 beschreibt außerdem ein haptisches Statussignal mittels Vibration des elektronischen Schlüssels.Out DE 103 39 293 A1 methods are known which provide optical or acoustic signals which indicate that the vehicle is not locked. However, this can go unnoticed by ambient noise or inattentiveness. DE 103 39 293 A1 also describes a haptic status signal by means of vibration of the electronic key.

Die DE 37 40 770 A1 schlägt vor, einen Schlüssel zu verwenden, der aufgrund eines eingebauten Motors mit umlaufender Unwucht durch Vibration ein nicht verriegeltes Fahrzeug anzeigt, wenn er aus einem bestimmten Umkreis des Fahrzeugs verbracht wird. Eine solche haptische Anzeige wird eher wahrgenommen als optische Signale, wenn der Schlüssel in der Hand oder aber auch in der Hosentasche getragen wird.The DE 37 40 770 A1 suggests using a key which, due to a built-in motor with a rotating imbalance, vibrates to indicate that the vehicle is not locked if it is moved outside of a certain radius of the vehicle. Such a haptic display is more likely to be perceived than optical signals when the key is carried in the hand or in a trouser pocket.

Dem gegenüber schlägt die Erfindung einen Schlüssel zum kontaktlosen Ver- und Entriegeln von Fahrzeugen vor, der mit einem Gehäuse für zumindest eine elektrische oder elektronische Schaltung gebildet ist, dessen Form durch elektrisch oder elektronisch gesteuerte Betätigung veränderbar ausgebildet ist. In contrast, the invention proposes a key for contactless locking and unlocking of vehicles, which is formed with a housing for at least one electrical or electronic circuit, the shape of which can be changed by electrically or electronically controlled actuation.

Die Erfindung betrifft außerdem ein Verfahren zum Erzeugen einer Rückmeldung eines Fahrzeugs auf ein Verriegelungssignal von einem Schlüssel über eine Funkstrecke, wobei als Rückmeldung für das erfolgreiche Verriegeln ein haptisches Signal im Schlüssel erzeugt wird.The invention also relates to a method for generating feedback from a vehicle to a locking signal from a key via a radio link, a haptic signal being generated in the key as feedback for successful locking.

In vorteilhafter Weiterbildung der Erfindung erfolgt die Veränderung der Gehäuseform des Schlüssels durch ein Ausbauchen. Dies kann beispielsweise durch einen motorisch bewegten Exzenter im Gehäuse erfolgen.In an advantageous development of the invention, the shape of the housing of the key is changed by bulging. This can be done, for example, by a motorized eccentric in the housing.

Eine weitere Ausbildung eines erfindungsgemäßen Schlüsselgehäuses sieht vor, dass die Oberfläche des Gehäuses veränderbar ausgebildet ist. Insbesondere kann die Veränderung zu einer Rauhigkeit der Gehäuseoberfläche führen, die haptisch wahrnehmbar ist.Another embodiment of a key housing according to the invention provides that the surface of the housing is designed to be changeable. In particular, the change can lead to a roughness of the housing surface that is haptically perceptible.

In vorteilhafter Weise können in das Gehäuse ausfahrbare Stifte integriert sein, die im ausgefahrenen Zustand eine haptisch wahrnehmbare Rauhigkeit der Oberfläche bewirken.In an advantageous manner, extendable pins can be integrated into the housing, which in the extended state produce a haptically perceptible roughness of the surface.

Von besonderem Vorteil ist es, wenn bei einem erfindungsgemäßen Verfahren ein Schlüssel mit einer veränderbaren Gehäuseform verwendet wird.It is particularly advantageous if a key with a variable housing shape is used in a method according to the invention.
