Abstract

The central locking device is operated by remotely radio controlled control device. The control device has an antenna (7) for receiving signals transmitted from the remote control. The control device also has a connection to the locking unit by a cable loom (2). The antenna is an integral part of the cable loom. In one embodiment the end of the antenna furthest away from the control device is fixed in a plastic rail (9) which is fixed to part of the chassis. The plastic rail may fit in holes in the chassis.

Description

Die Erfindung betrifft eine zentrale Verriegelungsanlage für ein Kraftfahrzeug, welche mittels eines durch eine Funkfernbedienung ansteuerbaren Steuergerätes betätigbar ist, bei der das Steuergerät eine Antenne zum Empfang der von der Funkfernbedienung ausgesendeten Signale aufweist und bei der das Steuergerät über einen Kabelbaum mit Ver­ riegelungseinheiten Verbindung hat.The invention relates to a central locking system for a motor vehicle, which by means of a Radio remote control controllable control unit can be operated is in which the control unit has an antenna for receiving the signals transmitted by the radio remote control and where the control unit has a wiring harness with Ver locking units connection.

Verriegelungsanlagen der vorstehenden Art werden derzeit in Kraftfahrzeugen eingebaut und sind deshalb allgemein bekannt. Solche funkferngesteuerten Verriegelungsanlagen haben gegenüber den am meisten verbreitesten Anlagen mit Infrarotlicht den Vorteil, daß zwischen der Funkfernbe­ dienung und dem Steuergerät mit dem Empfangsteil keine Sichtverbindung bestehen muß. Dadurch ist es möglich, die Verriegelungsanlage aus allen Positionen in der Nähe des Kraftfahrzeugs mittels der Funkfernsteuerung zu betäti­ gen.Locking systems of the above type are currently in use installed in motor vehicles and are therefore general known. Such radio-controlled locking systems have with the most widespread facilities Infrared light has the advantage that between the radio remote service and the control unit with the receiving part none Line of sight must exist. This makes it possible to Locking system from all positions near the Actuate motor vehicle using the radio remote control gene.

Nachteilig bei funkferngesteuerten Zentralverriegelungs­ anlagen ist es jedoch, daß diese eine Antenne benötigen, welche bislang aus Kostengründen unmittelbar am Steuerge­ rät angeordnet wurde. Es hat sich jedoch gezeigt, daß sich mit einer solchen Antennenanordnung immer noch Be­ reiche ergeben, in denen ein Ansteuern des Steuergerätes mit der Funkfernbedienung nicht möglich ist. Deshalb wäre es vorteilhafter, wenn man die Antenne an einem für den Funkempfang optimaleren Ort anordnen würde, was jedoch aus Kostengründen bislang nicht erfolgte.A disadvantage of radio-controlled central locking systems, however, they need an antenna, which so far has been directly at the tax area for cost reasons advised was ordered. However, it has been shown that  Be still with such an antenna arrangement rich result in a control of the control unit is not possible with the radio remote control. Therefore would be it is more advantageous if you connect the antenna to one for the Would arrange radio reception more optimal place, however not yet done for cost reasons.

Der Erfindung liegt das Problem zugrunde, eine zentrale Verriegelungsanlage der eingangs genannten Art so auszu­ bilden, daß die erforderliche Anordnung der Antenne mög­ lichst kostengünstig und möglichst wirkungsvoll im Hin­ blick auf einen Empfang von Signalen aus beliebigen Rich­ tungen ist.The problem underlying the invention is a central one Lock system of the type mentioned above form that the required arrangement of the antenna possible as inexpensive and as effective as possible in the outward direction look at receiving signals from any rich is.

Dieses Problem wird erfindungsgemäß dadurch gelöst, daß die Antenne zumindest teilweise einen Bestandteil des Ka­ belbaumes bildet.This problem is solved according to the invention in that the antenna is at least partially a component of the Ka belbaumes forms.

Durch diese Gestaltung kann man die Antenne mit sehr ge­ ringem Kostenaufwand auch von dem Steuergerät entfernt anordnen, wodurch die Möglichkeit entsteht, diese an ei­ nem solchen Ort zu montieren, wo Signale aus beliebigen Richtungen optimal empfangen werden können.This design allows the antenna to be very ge low cost also removed from the control unit arrange, which creates the possibility to send this to egg in such a place where signals from any Directions can be optimally received.

Die Montage der Antenne kann besonders rasch erfolgen, wenn gemäß einer Weiterbildung der Erfindung das dem Steuergerät abgewandte Antennenende in einer zum Befesti­ gen an einem Karosserieteil ausgebildeten Kunststoff­ schiene fixiert ist.The antenna can be installed particularly quickly, if according to a development of the invention that Antenna end facing away from control unit in one for fastening plastic formed on a body part rail is fixed.

Die Befestigung der Kunststoffschiene am Kraftfahrzeug kann ohne Werkzeug und ohne separate Befestigungsmittel durchgeführt werden, wenn gemäß einer anderen Weiterbil­ dung der Erfindung die Kunststoffschiene zum Verrasten in Bohrungen des Karosserieteils ausgebildet ist. The attachment of the plastic rail to the motor vehicle can be done without tools and without separate fasteners be carried out if, according to another ref extension of the invention, the plastic rail for locking in Bores of the body part is formed.  

Die Antenne ist optimal im Hinblick auf einen Empfang von Funksignalen aus beliebigen Richtungen angeordnet, wenn als Kabelbaum für die Antenne ein entlang der A-Säule des Kraftfahrzeugs führender Kabelbaum benutzt ist.The antenna is optimal for receiving Radio signals arranged from any direction, if as a wiring harness for the antenna along the A-pillar of the Motor vehicle leading wiring harness is used.

Die Erfindung läßt verschiedene Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine da­ von schematisch in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt inThe invention allows various embodiments. For there is a further clarification of their basic principle of is shown schematically in the drawing and is described below. This shows in

Die Fig. 1 zeigt einen Teilbereich einer Kraftfahrzeug­ karosserie 1, in welcher ein Kabelbaum 2 von einem Motor­ raum 3 an einer A-Säule 4 vorbei zu anderen Bereichen des Kraftfahrzeugs verläuft. Im Kraftfahrzeug ist ein Steuer­ gerät 5 angeordnet, welches Funksignale von einer nicht gezeigten, vom Fahrer des Kraftfahrzeugs mitgeführten Funkfernsteuerung zu erhalten vermag. Von dem Steuergerät 5 führt eine mit dem Steuergerät 5 durch einen Geräte­ stecker 14 verbundene Antennenzuleitung 6 durch den Ka­ belbaum 2, welche einen Bestandteil einer Antenne 7 bil­ det. Diese Antenne 7 hat ein Antennenende 8, welches mit­ tels einer Kunststoffschiene 9 an der A-Säule 4 befestigt ist. Fig. 1 shows a portion of a motor vehicle body 1 , in which a wiring harness 2 from an engine room 3 past an A-pillar 4 to other areas of the motor vehicle.
