Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Betätigung einer Tür oder Klappe eines Fahrzeugs, wobei die Vorrichtung eine Sensoreinheit aufweist, um eine Detektion eines Objektes in wenigstens einem an das Kraftfahrzeug angrenzenden Detektionsbereich zu ermöglichen, so dass über die Detektion die Betätigung des beweglichen Teils aktivierbar ist.The invention relates to a device for actuating a door or flap of a vehicle, wherein the device has a sensor unit in order to enable detection of an object in at least one detection area adjacent to the motor vehicle, so that the detection of the actuation of the movable part can be activated.
Aus dem Stand der Technik ist eine Sensoreinheit bekannt, welche an einem Stoßfänger angeordnet ist. Bei der Sensoreinheit handelt es sich um eine Eindrahtelektrode, welche als Seele einen Kupferdraht aufweist, die von einer Kunststoffschicht ummantelt ist. Nachteilig bei solch einer Sensoreinheit ist allerdings die geringe Reichweite zur Erfassung des Benutzers, welcher sich der Heckklappe nähert. Der Sensor detektiert den Benutzer erst knapp vor dem Stoßfänger, so dass bei einem schlüsselfreien Schließsystem sich die Heckklappe erst sehr spät öffnet.From the prior art, a sensor unit is known, which is arranged on a bumper. The sensor unit is a single-wire electrode, which has a copper wire as the core, which is encased by a plastic layer. A disadvantage of such a sensor unit, however, is the low range for detecting the user, which approaches the tailgate. The sensor only detects the user just in front of the bumper, so that with a key-free locking system, the tailgate opens very late.
Aufgabe der Erfindung ist es daher eine Vorrichtung zur Betätigung einer Tür oder Klappe eines Fahrzeugs mit einer Sensoreinheit bereitzustellen, die eine größere Reichweite zur Detektion des Benutzers aufweist.The object of the invention is therefore to provide a device for actuating a door or flap of a vehicle with a sensor unit, which has a greater range for the detection of the user.
Die Erfindung wird dadurch gelöst, dass die Sensoreinheit als Koaxialkabel ausgebildet ist, wobei ein als metallische Seele ausgebildeter Leiter des Koaxialkabels als aktive Abschirmung dient.The invention is achieved in that the sensor unit is designed as a coaxial cable, wherein a designed as a metallic core conductor of the coaxial cable serves as an active shield.
Die erfindungsgemäße Lösung bietet den Vorteil, dass die Reichweite der Sensoreinheit zur Detektion des sich an die Heckklappe annähernden Benutzers vergrößert wird. Dadurch wird bereits frühzeitig die Kommunikation zwischen einem Fahrzeugsteuergerät und einem Funkschlüssel des Benutzers gestartet, so dass bereits bei der Annäherung des Benutzers an die Heckklappe diese geöffnet wird.The solution according to the invention has the advantage that the range of the sensor unit for detecting the approaching to the tailgate user is increased. As a result, the communication between a vehicle control unit and a radio key of the user is started at an early stage, so that it is already opened when the user approaches the tailgate.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass der Leiter des Koaxialkabels zumindest teilweise von einer ersten Isolierschicht des Koaxialkabels ummantelt ist.According to a further preferred embodiment of the invention, it is provided that the conductor of the coaxial cable is at least partially encased by a first insulating layer of the coaxial cable.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die erste Isolierschicht des Koaxialkabels ein εr aufweist, welches einen Wert zwischen 5 und 1 aufweist. Der Vorteil ist, dass dadurch die Reichweite der Sensoreinheit vergrößert wird, weil das elektrische Feld einen größeren Detektionsbereich erzeugt.According to a further preferred embodiment of the invention, it is provided that the first insulating layer of the coaxial cable has an ε r , which has a value between 5 and 1. The advantage is that thereby the range of the sensor unit is increased, because the electric field generates a larger detection area.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die erste Isolierschicht aus einem geschäumten Material besteht, welches Luftkammern aufweist.According to a further preferred embodiment of the invention it is provided that the first insulating layer consists of a foamed material having air chambers.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die erste Isolierschicht aus Luft besteht.According to a further preferred embodiment of the invention, it is provided that the first insulating layer consists of air.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die erste Isolierschicht zumindest teilweise von einer metallischen Schicht ummantelt ist, welche als Sensorelektrode dient.According to a further preferred embodiment of the invention it is provided that the first insulating layer is at least partially covered by a metallic layer which serves as a sensor electrode.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die metallische Schicht als Metallfolie und/oder Drahtgeflecht und/oder Draht, insbesondere als spiralförmig aufgewickelter Draht ausgebildet ist.According to a further preferred embodiment of the invention it is provided that the metallic layer is formed as a metal foil and / or wire mesh and / or wire, in particular as a helically wound wire.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die metallische Schicht zumindest teilweise von einer zweiten Isolierschicht, insbesondere aus Kunststoff ausgebildeten Isolierschicht, ummantelt ist, welche zur Isolierung gegen äußere Umwelteinflüsse dient, insbesondere um die metallischen Anteile des Koaxialkabel gegen Feuchtigkeit und Korrosion zu schützen.According to a further preferred embodiment of the invention it is provided that the metallic layer is at least partially encased by a second insulating layer, in particular made of plastic insulating layer, which serves to insulate against external environmental influences, in particular to the metallic portions of the coaxial cable against moisture and corrosion protect.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Seele als Kupferdraht ausgebildet ist.According to a further preferred embodiment of the invention, it is provided that the core is formed as a copper wire.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Sensoreinrichtung an einem Stoßfänger angeordnet ist.According to a further preferred embodiment of the invention, it is provided that the sensor device is arranged on a bumper.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass das als Sensoreinheit ausgebildete Koaxialkabel an mindestens einem Ende wasserdicht ausgebildet ist. Dadurch wird in vorteilhafterweise ausgeschlossen, dass Feuchtigkeit in die einzelnen Schichten der Sensoreinheit eindringt und das elektrische Feld, welches durch die Sensoreinheit erzeugt wird, gestört wird.According to a further preferred embodiment of the invention, it is provided that the coaxial cable designed as a sensor unit is formed watertight at at least one end. As a result, it is advantageously precluded that moisture penetrates into the individual layers of the sensor unit and the electric field generated by the sensor unit is disturbed.
