Description

Die Erfindung bezieht sich auf eine Einrichtung zur Identifizierung von Kraftfahrzeugen, bestehend aus längs der Verkehrs- wege ortsfest angeordneten Lesestellen und am Kraftfahrzeug montierten Antwortgeräten.The invention relates to a device for identifying motor vehicles, consisting of reading points arranged in a fixed manner along the traffic routes and response devices mounted on the motor vehicle.

Derartige Einrichtungen haben ein breites Anwendungsgebiet. Bei Mautstellen, beispielsweise auf Autobahnen, vor Brücken und Tunnels läßt sich durch die automatische Identifizierung der Kraftfahrzeuge außer der Personaleinsparung eine erhebliche Erhöhung Des Durchsatzes erreichen. Eine entsprechende Bedeutung haben solche Einrichtungen auch für die Halter von geschlossenen Kfz-Flo-;ten, nämlich Polizei, Feuerwehr, Tanklastwagen, Betriebsfahrzeuge und dgl.Such devices have a wide range of applications. At toll booths, for example on motorways, in front of bridges and tunnels, the automatic identification of the motor vehicles, in addition to saving personnel, can significantly increase throughput. Such devices also have a corresponding meaning for the owners of closed motor vehicle fleets, namely the police, fire brigade, tank trucks, company vehicles and the like.

Bei bisherigen Identifizierungssystemen ist die Lesestelle entweder in der Fahrbahndecke eingebaut und die Antwortgeräte dementsprechend unter dem Fahrzeug befestigt oder aber die Identifizierung wird von der Straßenseite aus -durchgeführt. Bei beiden Varianten überwiegen jedoch die Nachteile gegenüber den Vorteilen. So ist beim Einbau der Lesestelle in die Fahrbahn nachteilig, daß wegen dämpfender Wirkungen von Wasser- und Schneeschichten .der Fahrbahn die Informationsübertragung von vornherein auf den tiefen NHz- bzw. kHZ-Frequenzbereich beschränkt wird. Wegen hoher Installations- und Wartungskosten ist zudem der wirtschaftliche Aufwand erheblich. Außerdem kann das Antwortgerät auf der Fahrzeugunterseite beschädigt oder durch Verschmutzung in seiner Funktion beeinträchtigt werden.In previous identification systems, the reading point is either built into the road surface and the answering devices are accordingly attached under the vehicle, or the identification is carried out from the street side. In both variants, however, the disadvantages outweigh the advantages. It is disadvantageous when installing the reading point in the carriageway that, due to the dampening effects of layers of water and snow, the carriageway limits information transmission from the outset to the low NHz or kHZ frequency range. Due to high installation and maintenance costs, the economic effort is also considerable. In addition, the transponder can be placed on the vehicle side damaged or its function impaired by dirt.

Bei Identifizierungssystemen mit seitlich angeordneten Lesestellen und Antwortgeräten treten besonders bei mehrspurigen Straßen wegen Abdeckung durch benachbarte Fahrzeuge erhebliche Probleme auf. Schwierig ist auch die Anbringung des Antwortgerätes an der Kraftfahrzeugseite, das zudem wegen möglicher mechanischer Beschädigungen und Beeinflussung durch Drittpersonen gefährdet ist.In identification systems with reading points and answering devices arranged on the side, considerable problems arise, particularly on multi-lane roads, because they are covered by neighboring vehicles. It is also difficult to attach the responder to the motor vehicle side, which is also at risk due to possible mechanical damage and interference by third parties.

Der Erfindung liegt die Aufgabe zugrunde, für eine Einrichtung zur Identifizierung von Fahrzeugen eine Lösung anzugeben, die die vorstehend aufgeführten Nachteile vermeidet.The invention has for its object to provide a device for identifying vehicles that avoids the disadvantages listed above.

Diese Aufgabe wird gemäß der Erfindung in der Weise gelöst, daß die Lesestellen über der Fahrbahn, beispielsweise an Durchfahrten, Brücken oder Lichtmasten, angebracht sind mit senkrecht nach unten oder schräg nach vorn verlaufender Strahlungsrichtung und daß das Antwortgerät jeweils im Fahrzeuginneren an der Windschutzscheibe (Frontscheibe), am Rückspiegel oder einem anderen von oben bzw. von vorn durch die Lesestelle gut erfaßbaren Platz montiert ist.This object is achieved according to the invention in such a way that the reading points above the road, for example on passageways, bridges or light poles, are attached with a radiation direction extending vertically downwards or obliquely to the front and that the responder is in each case inside the vehicle on the windshield (windscreen ), on the rear-view mirror or another place that can be easily grasped from above or from the front by the reading point.

Das Antwortgerät weist in vorteilhafter Weise eine sehr flache Ausführungsform auf ( < 10 mm) und wird an der Innenseite der Windschutzscheibe aufgeklebt. Dadurch können einerseits bei Übertragungsfrequenzen oberhalb 1 GHz auftretende störende Reflexionen an der Glasscheibe auf ein Minimum reduziert werden, andererseits läßt sich dadurch das Gerät so ausbilden, daß eine zerstörungsfreie Demontage durch Unbefugte nicht möglich ist, was eine zusätzliche Diebstahlsicherung darstellt.The answering device advantageously has a very flat embodiment (<10 mm) and is glued to the inside of the windshield. On the one hand, this can reduce disturbing reflections on the glass pane at transmission frequencies above 1 GHz to a minimum, on the other hand, the device can be designed in such a way that non-destructive disassembly by unauthorized persons is not possible, which represents an additional anti-theft device.

In vorteilhafter Weiterbildung des Anmeldungsgegenstandes ist vorgesehen, daß das Antwortgerät Informationsträger in Form von Codekarten enthält, die in vorteilhafter Weise auswechselbar ausgebildet sind. Durch Einschieben eines zusätzlichen Informationsträgers kann somit der Informationsträgerteil des Antwortgerätes geändert werden. Die Codekarten, beispielsweise Lochkarten, Magnetkarten oder Karten mit Halbleiterspeichern, gestatten es dem Befugten, das Antwortgerät in eindeutiger Weise einzustellen. Dadurch läßt sich ein Mißbrauch des Fahrzeuges verhindern. Falls das Antwortgerät auf den Zündkreis des Fahrzeuges eingreift, kann die Codekarte als Diebstahlsicherung für das Kraftfahrzeug dienen. In Kombination mit der Diebstahlsicherheit des Antwortgerätes stellt die Codekarte ein fälschungssicheres Kennzeichen dar.In an advantageous development of the subject of the application, it is provided that the answering device contains information carriers in the form of code cards which are advantageously designed to be exchangeable. By inserting an additional information carrier, the information carrier part of the answer can thus device can be changed. The code cards, for example punch cards, magnetic cards or cards with semiconductor memories, allow the authorized person to set the answering device in a clear manner. This prevents misuse of the vehicle. If the response device intervenes in the ignition circuit of the vehicle, the code card can serve as an anti-theft device for the motor vehicle. In combination with the anti-theft security of the answering device, the code card is a forgery-proof indicator.

In vorteilhafter Weiterbildung des Anmeldungsgegenstandes ist ferner vorgesehen, daß der Informationsinhalt des Antwortgerätes durch Anlegen von Steuerspannungen elektronisch-ferneinstellbar ist. Damit kann z.B. mittels einer Tastatur am Armaturenbrett ein nur dem Fahrer bekannter Code eingegeben werden. Dieses fernsteuerbare Antwortgerät kann auch an das Zündschloß des Fahrzeuges angeschlossen werden, womit es entweder lediglich aktiviert oder über die Kombination des Schlüssels ferneingestellt werden kann. Dies ergibt zugleich eine zusätzliche Diebstahlsicherung des Fahrzeuges.In an advantageous further development of the subject of the application, it is further provided that the information content of the responder can be remotely adjusted electronically by applying control voltages. With this e.g. a code known only to the driver can be entered using a keyboard on the dashboard. This remote-controllable answering device can also be connected to the ignition lock of the vehicle, whereby it can either only be activated or set remotely using the combination of the keys. This also provides additional anti-theft protection for the vehicle.

Nachstehend wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert.The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the drawing.

Es zeigen

  • Fig. 1 und 2 zwei Ausführungsformen für die Anbringung der Lesestellen über der Fahrbahn,
  • Fig. 3 und 4 Ausführungsformen und Befestigung des Antwortgerätes im Fahrzeug.
Show it
  • 1 and 2, two embodiments for the attachment of the reading points above the road,
  • 3 and 4 embodiments and attachment of the responder in the vehicle.

Fig. 1 zeigt eine Durchfahrt für Kraftfahrzeuge, beispielsweise eine Maut- oder Zollstelle, bei der eine sich über alle Fahrspuren erstreckende Überdachung vorgesehen ist. An der Stirnseite des Daches 1 sind in Richtung der ankommenden Fahrzeuge jeweils über den einzelnen Fahrspuren mit Strahlrichtung schräg nach vorn auf die entgegenkommenden Fahrzeuge Lesestellen 2 angebracht. Von den Lesestellen 2 werden die Informationen der Antwortgeräte 5 der Fahrzeuge 3 erfaßt. In der Figur ist ein solches Antwortgerät 5 beim Fahrzeug in der rechten Fahrspur und bei den Fahrzeugen der Gegenfahrbahn erkennbar.1 shows a passage for motor vehicles, for example a toll or customs office, in which a roof is provided which extends over all lanes. On the front side of the roof 1, reading points 2 are attached to the oncoming vehicles in the direction of the arriving vehicles each above the individual lanes with the beam direction obliquely forward. From the reading points 2 the information of the answering devices 5 of the Vehicles 3 detected. Such a response device 5 can be seen in the figure in the vehicle in the right lane and in the vehicles in the opposite lane.

Fig. 2 zeigt als weitere Möglichkeit der Anordnung von Lesestellen eine sich über eine breite Fahrbahn mit mehreren Fahrspuren erstreckende Brücke 7. Auf der dem ankommenden Verkehr zugekehrten Seite der Brücke sind über den einzelnen Fahrspuren jeweils Lesestellen 2 angebracht, die senkrecht nach unten strahlen. Die über der rechten Fahrbahnseite angeordneten Lesestellen, also im Bild dem Betrachter zugekehrten Lesestellen, sind über ausgezogene gezeichnete Linien miteinander verbunden, die über der linken Fahrbahnseite angeordneten Lesestellen, also den Gegenverkehr erfassenden Lesestellen, sind mit strichlierten Linien miteinander verbunden. Eine Verbindungsleitung 8 führt zu einer Zentrale, ineder die Informationen der Lesestellen ausgewertet werden.2 shows, as a further possibility of arranging reading points, a bridge 7 which extends over a wide carriageway with several lanes. On the side of the bridge facing the incoming traffic, reading points 2 are attached above the individual lanes and radiate vertically downwards. The reading points arranged above the right side of the lane, i.e. the reading points facing the viewer in the picture, are connected by solid drawn lines, the reading points arranged above the left side of the lane, i.e. reading points that detect oncoming traffic, are connected by dashed lines. A connecting line 8 leads to a center in which the information from the reading points is evaluated.

Bei der Montage von Lesestellen über der Fahrbahn ergibt sich dabei die Möglichkeit, Fahrzeuge, die nicht mit Antwortgeräten ausgerüstet sind bzw. deren Antwortgerät defekt ist, mit einem geringfügig erweiterten Lesesystem zu erfassen, z.B. durch Messung der Reflexionsfaktoränderung oder des Dopplereffektes.When reading points are installed above the carriageway, there is the possibility of detecting vehicles that are not equipped with answering devices or whose answering device is defective with a slightly expanded reading system, e.g. by measuring the change in reflection factor or the Doppler effect.

Fig. 3 zeigt die Anbringung des Antwortgerätes in einem Fahrzeug, LKW und eines und zwar an der Windschutzscheibe 4 eines/in der Seitenansicht und in der Draufsicht dargestellten PKW 3. Das Antwortgerät 5 ist hierbei extrem flach ausgebildet und an der Innenseite der vorderen Windschutzscheibe (Frontscheibe) aufgeklebt. Die Montage erfolgt dabei, um Sichtbehinderung zu vermeiden, oben hinter dem Rückspiegel oder in einer der Ecken der Windschutzscheibe.3 shows the attachment of the answering device in a vehicle, truck and one, namely on the windshield 4 of a car 3 shown in the side view and in the top view. The answering device 5 is designed to be extremely flat and on the inside of the front windshield ( Windscreen) glued on. To avoid obstruction, the assembly is carried out at the top behind the rear view mirror or in one of the corners of the windshield.

Fig. 4 zeigt die Montage des Antwortgerätes 5 am inneren Rückspiegel 6 des Fahrzeugs, und zwar an dem Haltestab. Ein Antwortgerät extrem dünner Ausführung kann auch an der Rückseite des Innenspiegels befestigt, insbesondere aufgeklebt werden, wie dies vorstehend bei der Ausführungsform des auf der Windschutzscheibe aufgeklebten Antwortgerätes beschrieben ist.Fig. 4 shows the assembly of the answering device 5 on the inner rear view mirror 6 of the vehicle, specifically on the holding rod. An extremely thin version of a responder can also be attached to the rear of the inside mirror, in particular glued on, as described above in the embodiment of the responder attached to the windshield.

Das Antwortgerät läßt sich auch im Armaturenbrett unterbringen. In diesem Fall wird die zugehörige Antenne in vorteilhafter Weise auf der vorderen Windschutzscheibe aufgebracht. Diese kann beispielsweise als Klebfolie ausgebildet sein.The transponder can also be placed in the dashboard. In this case, the associated antenna is advantageously applied to the front windshield. This can be designed, for example, as an adhesive film.
