Description

The invention relates to an identification system for identification tion of motor vehicles according to the preamble of the patent saying 1.

So far, it is only known a motor vehicle after Identify license plate or after the permanent on Chassis attached chassis number. When identifying ornamentation of the motor vehicle based on the license plate the disadvantage that the license plate is very easily replaced can be or can be faked, which means that this System not for secure identification of the vehicle is suitable.

When using chassis numbers for identification the motor vehicle is very expensive because the Chassis numbers are usually in hidden places of the chassis arranged in the engine compartment, what their on findability very difficult. In addition, the after exists part that these chassis numbers are not counterfeit-proof are designed because they can be ground or it complete frame parts can even be removed and replaced by other frame parts with different chassis numbers will. The disadvantage of this chassis number system is therefore the relatively difficult accessibility and the lack of readability from the outside. So it is not possible, for example parked vehicle whose bonnet is closed by to see from the outside whether it is stolen or not. Such However, controls are desirable because they are dormant Traffic can be checked for stolen vehicles and in addition, such controls are at the border entrance and exit  corridors desirable because quick identification of the vehicle for the purpose of theft detection advantageous is.

The invention is therefore based on the task of identi fication system for marking motor vehicles so train that quick identification of the force vehicle is also possible with the hood not open, which Identification trained against theft and counterfeiting should be.

To achieve the object, the invention is by characterized technical teaching of claim 1.

An essential feature of the invention is that now erfindungsge according to a visible surface of the motor vehicle, preferably the Rear window or the front window of the motor vehicle or several identification modules (hereinafter ID modules ge named) are attached, the ID modules being tamper-proof carry vehicle-specific data. Such data are e.g. B. the chassis number, the engine number, the color of the Vehicle, the type, the key number of the vehicle and of the manufacturer and the like. Data more.

It is preferred here if already at the manufacturer provision of such ID modules with the vehicle-specific Data is programmed to ensure that this ID module reliably and permanently attached to the motor vehicle and on the other hand carries the "right" data.

In another embodiment of the present invention provided that such ID modules subsequently on the motor vehicle are permanently attachable and that by authorized and approved programming points the vehicle-specific Data can be programmed into these modules.  

Another embodiment of the present invention provides before that the ID modules with permanently programmed and indelible unique numbers. The assignment between one Motor vehicle and an ID module is therefore unique and one times.

According to a preferred embodiment of the invention one or more ID modules in the pane area, preferably the Rear or front window area of the respective vehicle brings. This solution has the advantage that the ID modules from are clearly visible from the outside and from the outside by appropriate con trollers are also easily accessible. The reading takes place then, for example, contactlessly via corresponding readout channels devices that optically, acoustically (ultrasound), kapa the ID module Scan and read out quotatively or inductively. The ID modules can can be designed both electrically passive and only by closing management of an external energy from the reader or they can be designed as active transmitters themselves, then the power supply over corresponding permanent Power supplies must be secured, such as. B. solar cells, Induction loops or the like

In all applications it is important that the ID module is a is permanently connected to the vehicle and others is readable from the outside, whereby for reading the previously mentioned readers can be used. Self Ver Of course, it is possible to use different readers Execute embodiments.

In a first embodiment, it is preferred if the readout device is designed as a type of readout gun det is what you can do by placing the read head on the corresponding ID module from this the vehicle-specific Omits data.  

In another embodiment it is provided that the ID Module always or only under certain circumstances electrical becomes active as a transmitter and its vehicle-specific data sends out. For example, he can send such a message follow if the ID module by appropriate induction grinding in the driving area (e.g. on the road floor, at traffic lights masts, on bridges) and at these readout points sends out a corresponding vehicle-specific code.

To further improve the security against theft of the ID modules it is provided that this is only damaged from the vehicle or can be removed from the vehicle.

It is provided in a first embodiment that the ID module is designed as a badge that is permanent and protected against detaching on the inside of the rear window of the vehicle or on the inside of the windscreen is glued. A badge can be used here the one that has a bar code, the badge itself with a hologram on the back or in the front area can be combined to destroy the badge immediately make visible. The barcode then gives the fahrzeugspe specific data again and can be read using a simple reader can be read from the outside.

To further improve theft security is pre see that another badge stuck in the body area is arranged on the body area and z. B. in immediate Neighborhood to the plaque arranged in the pane area is arranged. For example, if an ID module is on the left Side of the rear window is attached, the second ID could Module to be attached to the left C-pillar of the body. So it is a paired arrangement of two ID Modules, both of which can be read out together. Both included  the vehicle-specific data, the data of the in the Rear window arranged module from the data of the at the C- Column arranged module can deviate to an abuse prevent exchange.

The advantage of the entire system is that the vehicle-specific Data with simple readers, even when the vehicle is stationary and are easy to read when the bonnet is closed, so that stolen vehicles are more easily identified and restored can be found.

Such controls are then not only required in manufacturing country of the vehicle, but it is possible Lich, the appropriate reader with a permanent Storage provided, in this memory all stolen Vehicles are stored. With such a reader you can then check vehicles parked abroad, that still have such ID modules.

The subject matter of the present invention provides not only from the subject of each patent sayings, but also from the combination of the individual Pa claims among themselves. All in the records, one finally the summary, disclosed information and Features, especially those shown in the drawings spatial training are claimed as essential to the invention, as far as they stand individually or in combination with the stand of technology are new.

The invention is based on several embodiments way illustrated drawings explained in more detail. Go here from the drawings and their description further fiction essential features and advantages of the invention.

Fig. 2 shows an exemplary embodiment of the front of an ID module,

Fig. 3 shows an exemplary embodiment of the back of an ID module,

Fig. 4 is a reader for reading another execution form of an ID module,

Fig. 5 schematically a structure of an ID module of Fig. 4.

In a motor vehicle 1 there is a rear window 2 , which is embedded in the body 4 in a manner known per se. According to the invention, a first ID module 5 is now permanently attached to one side of the rear window 2 , several attachment options being preferred here.

In a first embodiment it is provided that the ID module 5 shown in FIGS. 2 and 3 is glued to the inside of the rear window 2 and so permanently that a detachment of the badge 8 ( FIGS. 2, 3) leads to destruction badge.

In another embodiment it is provided that the badge 8 itself is welded or cast in between the individual layers of the rear window by the manufacturer, in order to ensure that the ID module can only be removed by disrupting the rear window itself.

Other security measures are also possible to ensure that the ID module 5 is also destroyed when the rear window 2 is destroyed. For example, it is possible to assign an acid store to the badge 8 and to cause the acid store to leak when the rear window 2 is opened, in order to thus destroy the material of the badge 8 .

The ID module can also be protected against changing the rear window 2 by in the area of the body 4 , z. B. in the area of the C-pillar 3 arranges a second ID module 6 , which contains the same vehicle-specific data ent, but which contains a code that says that this module is arranged in the body area.

By reading both ID modules 5 , 6 , the correct pairing, which must belong to the vehicle, can thus be ascertained and checked.

According to a preferred first embodiment, the ID module can be designed as a badge 8 and have a bar code 7 on the front which contains the vehicle-specific data in a manner known per se. The entire badge can have a hologram 9 on the rear side according to FIG. 3 in order to indicate destruction, wherein the hologram 9 can also be arranged directly on the front of the badge 8 .

The entire arrangement, which was described in Fig. 1, can also be arranged on the front of the vehicle in the region of the front window in connection with the A-pillar.

Such ID modules can also be located at other positions of the Vehicle be arranged, for. B. in the roof area, in the corner area or the like. more.

An ID module 5 , 6 can be read out with a reading device 10 according to FIG. 4, in which case the reading device 10 is equipped with an optically active reading head 15 .

In the embodiment shown in FIG. 4, however, another ID module 20 is shown, which is designed either as an elec trical or passive element.

If this element is designed as a passive element, then it is activated by a corresponding read pulse 16 from the read head 15 of the reading device 10 and, after the activation, sends a read pulse current 17 back into the read head 15 .

For this purpose, for example, a memory 13 can be arranged in the reading device 10 by storing all vehicle-specific data of all stolen vehicles.

The memory 13 can be coupled to a display 12 , which then reports the result of the reading (checking) of the ID modules 5 , 6 , 20 .

The housing 11 can of course contain other parts, such as. B. a holder 14 for activating the read head 15 or for activating the display and the like. More.

FIG. 5 shows a further example which is supplied by a power supply 18, an electrically active module ID. This power supply 18 can, for example, be a solar power supply after the ID modules have been at least temporarily irradiated with daylight by being mounted in the rear window or windscreen area.

It is also possible to design the power supply 18 as an induction coil, the power supply of the ID module 20 then being activated only by a corresponding induction current surge.

In the ID module 20 there is a memory 19 in which the vehicle-specific data are stored permanently and cannot be deleted or written over. This memory 19 can consist of all known storage media, such as. B. semi-conductor memory, optical memory, capacitive memory and other known storage media.

The memory 19 can activate a transmitter 21 , which transmits a transmission code 23 via an antenna 22 . In this way, the ID module 20 can then not only be read out via a reading device 10 , but it can also be read out remotely, by appropriate read-out devices arranged in the street area, which access the ID module 20 over a greater distance.

All vehicle-specific are in a central database fishing data of the stolen vehicles.

It is designed so that the vehicle-specific data of the Vehicles can be added or deleted, whereby these Database is preferred in public hands. Changes in Database will be communicated to the appropriate readers. The central database is part of a network of data banks, the databases among themselves from their data exchange, so that at any location on the network of data bank There is access to the entire database. Thereby is a local as well as a global verification option given without the administrative overhead of local databases to span.
