It comprises: - one or more display means 5, 6 displaying the "drive" or "parking" state; - an electronic control unit 4 with a microprocessor; - a validation means using a programmable specific signal which allows access to a control means which controls the state of the said vehicle 2. Anti-theft device especially for motor vehicles.

Description

L'invention a pour objet un dispositif antivol, notamment pour véhicules automobiles, comportant un moyen d'affichage extérieur codé, communiquant en permanence un signe tel que l'état "route" ou "stationnement" dudit véhicule. The subject of the invention is an anti-theft device, in particular for motor vehicles, comprising a coded exterior display means, permanently communicating a sign such as the "road" or "parking" state of said vehicle.

Actuellement, la majorité des dispositifs antivols empêchent les voleurs d'entrer dans le véhicule ou de l'utiliser, par exemple en bloquant l'arrivée du carburant, la colonne de direction, les freins. Ces dispositifs peuvent déclencher de nombreuses alarmes sonores. Si le voleur parvient à neutraliser l'alarme ou l'antivol proprement: dit, il peut utiliser le véhicule automobile sans-etre repérés
Certaines garanties sont offertes par les compagnies d'assurances ou par les constructeurs automobiles pour inciter les propriétaires de véhicules automobiles à faire graver toutes les vitres par une projection d'abrasif sur ane profondeur de deux centièmes de millimètre. Ce gravage indélébile du numéro d'immatriculation permet d'identifier le véhicule.Currently, the majority of anti-theft devices prevent thieves from entering or using the vehicle, for example by blocking the arrival of fuel, the steering column, the brakes. These devices can trigger numerous audible alarms. If the thief manages to neutralize the alarm or the anti-theft properly: said, he can use the motor vehicle without being spotted
Certain guarantees are offered by insurance companies or by automobile manufacturers to encourage the owners of motor vehicles to have all the windows engraved by a projection of abrasive on the depth of two hundredths of a millimeter. This indelible engraving of the registration number identifies the vehicle.

Cette dernière disposition n'est pas suffisante. Ce dernier dispositif implique, pour identifier le véhicule, que celui-ci soit à l'arrêt et de vérifier toutes les vitres, ce qui est fastidieux.The latter provision is not sufficient. This last device implies, to identify the vehicle, that it is stopped and to check all the windows, which is tedious.

L'invention tend à éviter tous ces inconvénients. The invention tends to avoid all of these drawbacks.

Le dispositif selon l'invention permet d'afficher en permanence un signal tel que l'état "route" ou "stationnement". Le dispositif d'affichage est codé, il permet au seul propriétaire d'afficher, par un moyen de validation, l'état de son véhicule. Si celui-ci est volé, il sera identifié immédiatement comme n'étant pas entre les mains de son propriétaire. The device according to the invention makes it possible to permanently display a signal such as the "road" or "parking" state. The display device is coded, it allows the sole owner to display, by means of validation, the state of his vehicle. If it is stolen, it will be identified immediately as not being in the hands of its owner.

A cet effet, le dispositif selon l'invention est composé
- d'une centrale de commande électronique à microprocesseur,
- d'un ou de plusieurs moyens d'affichage,
- d'un moyen de validation, par un signal spécifique programmable, qui permet l'accès à un moyen de commande qui commande l'état dudit véhicule,
- d'un relais coupe-circuit mettant le véhicule hors service en cas de signal spécifique (ou code) incorrect.To this end, the device according to the invention is composed
- an electronic control center with microprocessor,
- one or more display means,
- a validation means, by a specific programmable signal, which allows access to a control means which controls the state of said vehicle,
- a circuit breaker relay putting the vehicle out of service in the event of an incorrect specific signal (or code).

Le moyen d'affichage peut être un bloc alphanumérique à cristaux liquides illuminés soit en rouge, soit en vert ou tout autre couleur et affichant, par exemple, le numéro d'immatriculation du véhicule. The display means can be an alphanumeric block with liquid crystals illuminated either in red, in green or any other color and displaying, for example, the registration number of the vehicle.

Les moyens d'affichage peuvent être intégrés, par exemple, l'un au pare-brise avant et l'autre à la lunette arrière. The display means can be integrated, for example, one into the front windshield and the other into the rear window.

Lesdits moyens d'affichage peuvent être disposés de manière inviolable contre le pare-brise avant et la lunette arrière, par exemple par de la colle spéciale, dans un boitier blindé fixé à la carrosserie du véhicule... Said display means can be inviolably disposed against the front windshield and the rear window, for example by special glue, in an armored box fixed to the vehicle body ...

Ledit moyen de commande, pour composer le code et commander l'affichage de l'état du véhicule, peut être un clavier numérique à code et/ou un lecteur de carte magnétique. Des touches permettent de configurer les blocs d'afficheurs de manière adéquate "route" ou "stationnement". Said control means, for composing the code and controlling the display of the vehicle status, can be a code keypad and / or a magnetic card reader. Keys are used to configure the display blocks adequately "road" or "parking".

Les dessins ci-joints donnés à titre d'exemple indicatifs et non limitatifs permettront de comprendre aisément l'invention. Ils représentent un mode de réalisation préféré selon l'invention. The attached drawings given by way of non-limiting example will allow the invention to be easily understood. They represent a preferred embodiment according to the invention.

La figure 1 est une vue schématique de l'implantation du dispositif dans le véhicule automobile. Figure 1 is a schematic view of the installation of the device in the motor vehicle.

La figure 2 est un schéma synoptique du dispositif. Figure 2 is a block diagram of the device.

Dans la figure 1, le dispositif est branché sur la batterie 1 du véhicule automobile 2. Un relais coupe-circuit 3 est branché entre la centrale électronique 4 et la batterie 1. In FIG. 1, the device is connected to the battery 1 of the motor vehicle 2. A circuit breaker relay 3 is connected between the electronic control unit 4 and the battery 1.

La centrale électronique 4 est reliée au bloc d'afficheurs pare-brise 5 et au bloc d'afficheurs lunette arrière 6. The electronic control unit 4 is connected to the windshield display unit 5 and to the rear window display unit 6.

Sur la figure 2, on retrouve les éléments suivants réalisés autour d'un micro-processeur 15. In FIG. 2, we find the following elements produced around a microprocessor 15.

Un circuit 7, relié à la batterie 1 du véhicule et un relais de puissance coupe-circuit 3 ouvrent ou ferment le circuit électrique du véhicule. L'alimentation de la centrale 4 est prise en amont dudit relais 3. Un amplificateur ou bascule (Latche) 23 est relié d'une part au clavier de codage 8, d'autre part à un démultiplexeur 9. Le clavier 8 comporte dix touches de zéro à neuf, plus une touche S pour le "stationnement" et une touche R pour la "route". Ce clavier est relié à un encodeur 10 qui est relié, par une fiche multiple 11, au multiplexeur 9 et au bus de données 11 branché sur les mémoires EPROM 12 et RAM 13 ainsi que le bus d'adresses 14 qui est relié en plus au démultiplexeur 9. A circuit 7, connected to the vehicle battery 1 and a circuit breaker power relay 3 open or close the vehicle's electrical circuit. The power supply of the central unit 4 is taken upstream of said relay 3. An amplifier or rocker (Latche) 23 is connected on the one hand to the coding keyboard 8, on the other hand to a demultiplexer 9. The keyboard 8 has ten keys from zero to nine, plus an S key for "parking" and an R key for "road". This keyboard is connected to an encoder 10 which is connected, by a multiple plug 11, to the multiplexer 9 and to the data bus 11 connected to the EPROM memories 12 and RAM 13 as well as the address bus 14 which is additionally connected to the demultiplexer 9.

La mémoire programmable, non volatile, EPROM 12, renferme le code confidentiel utilisateur ainsi que le programme d'exploitation (initialisation du système, gestion des afurs et du clavier, comparaison des informations...). La mémoire vive RAM 13 stocke les informations provisoirement. The programmable, non-volatile memory, EPROM 12, contains the user confidential code as well as the operating program (system initialization, management of windows and keyboard, comparison of information, etc.). The RAM 13 stores the information temporarily.

Les bus de données 11 et d'adresses 14 sont branchés à un microprocesseur 15, par exemple de huit bits, muni d'une fonction "horloge" et "Reset" (remise à zéro). Ledit microprocesseur 15 est relié au clavier de codage 8 ou tout autre moyen de commande permettant l'identification du propriétaire par un signal personnalisé, par exemple un lecteur de carte magnétique.  The data bus 11 and address bus 14 are connected to a microprocessor 15, for example of eight bits, provided with a "clock" and "Reset" function. Said microprocessor 15 is connected to the coding keyboard 8 or any other control means allowing the identification of the owner by a personalized signal, for example a magnetic card reader.

Dans cette version, non repésentée sur les- figures, le code confidentiel est enregistré sur le support magnétique. In this version, not shown in the figures, the confidential code is recorded on the magnetic medium.

Les signaux entre l'unité centrale 4 et les blocs d'afficheurs 5,6 sont multiplexés et transmis en binaire, interdisant un accès "pirate" aux afficheurs 5,6. The signals between the central unit 4 and the display blocks 5,6 are multiplexed and transmitted in binary, preventing "pirate" access to the displays 5,6.

Les blocs d'afficheurs 5,6 se composent ainsi
- un bloc d'afficheurs 16, un démultiplexeur Driver 17 relié au bus d'adresses 11, un décodeur à seize segments 18, relié au bus de données 11,
- une lampe rouge 19 pour indiquer l'état de "stationnement",
- une lampe verte 20 pour indiquer l'état de "routez,
- un circuit 21 et des amplificateurs 22 pour l'alimentation desdites lampes 19 et 20.The display blocks 5.6 are thus composed
a block of displays 16, a Driver demultiplexer 17 connected to the address bus 11, a sixteen-segment decoder 18, connected to the data bus 11,
- a red lamp 19 to indicate the "parking" state,
- a green lamp 20 to indicate the status of "route,
a circuit 21 and amplifiers 22 for supplying said lamps 19 and 20.

Ledit circuit 21 est également relié aux bus de données 11 et aux bus d'adresses 14. Said circuit 21 is also connected to the data buses 11 and to the address buses 14.

L'utilisation du circuit permet de comprendre aisément l'intérêt de l'invention. The use of the circuit makes it easy to understand the advantage of the invention.

Le propriétaire du véhicule 2 ou l'utilisateur autorisé, après avoir pénétré dans ledit véhicule, compose sur le clavier de commande 8 son code secret et commande par la touche R l'affichage "route". The owner of the vehicle 2 or the authorized user, after having entered the said vehicle, dials the secret code on the control keyboard 8 and orders the "route" display using the R key.

L'affichage des blocs d'afficheurs 5 et 6 peut représenter un sigle ou le numéro d'immatriculation du véhicule 2, ou le numéro de la police d'assurance ou le numéro de la carte grise... En plus, la couleur verte ou rouge des lampes 19,20 permet de visualiser de loin l'état du vehicule. The display of display blocks 5 and 6 can represent an acronym or the vehicle registration number 2, or the insurance policy number or the registration card number ... In addition, the color green or red lamps 19,20 allows you to view the condition of the vehicle from a distance.

Les numéros de code, la carte magnétique qui commande le dispositif selon l'invention seront fournis par le constructeur automobile ou par tout autre autorité compétente, préfecture, organisme délivrant les papiers officiels du véhicule ou les compagnies d'assurances et ce dès lors que l'utilisateur sera en mesure de justifier la propriété ou son état de locataire du véhicule et/ou son état vis à vis de la législation en vigueur (assurance obligatoire...). The code numbers, the magnetic card which controls the device according to the invention will be supplied by the car manufacturer or by any other competent authority, prefecture, body issuing the official papers of the vehicle or the insurance companies, as soon as the The user will be able to justify the property or his condition as the lessee of the vehicle and / or his condition with regard to the legislation in force (compulsory insurance ...).

Sur route, toute personne intéressée ou toutes les autorités compétentes peuvent vérifier rapidement si un véhicule affiche l'état de "route" ou de "stationnement". En cas de doute, il suffit d'effectuer un contrôle sur ce véhicule. On the road, any interested person or all the competent authorities can quickly check whether a vehicle displays the status of "road" or "parking". In case of doubt, it is sufficient to carry out a check on this vehicle.

Lorsqu'il quitte son véhicule, l'utilisateur coupe le contact, puis par le clavier de codage 8 affiche l'état "stationnement". Si l'utilisateur oublie de modifier les blocs d'afficheurs après avoir coupé le contact et/ou quitté son véhicule, un signal sonore et/ou lumineux le lui rappelle. Les blocs d'afficheurs 5, 6 clignotent puis affichent le numéro d'immatriculation en rouge, alors qu'il était en vert pour l'état "route". When he leaves his vehicle, the user switches off the ignition, then by the coding keypad 8 displays the "parking" state. If the user forgets to modify the display blocks after switching off the ignition and / or leaving his vehicle, an audible and / or light signal reminds him. The display blocks 5, 6 flash and then display the registration number in red, while it was green for the "road" state.

Ainsi, très facilement, un véhicule 2 est repéré en stationnement lorsque ses blocs d'afficheurs ne sont pas allumés et de couleur rouge ou affichant le signal "stationnement". Ce dispcsitif facilite grandement la recherche de véhicules volés. Thus, very easily, a vehicle 2 is identified when parked when its display blocks are not lit and red in color or displaying the "parking" signal. This device greatly facilitates the search for stolen vehicles.

Pour utiliser à nouveau son véhicule, l'utilisateur doit envoyer son code sur le clavier 8 puis appuyer sur la touche "route", Si le numéro de code n'est pas bon, après un ou plusieurs essais ou après une temporisation déterminée, l'alimentation électrique du véhicule est coupee. To use his vehicle again, the user must send his code on the keypad 8 then press the "route" button. If the code number is not correct, after one or more tests or after a determined time delay, l vehicle's power supply is cut.

Le dispositif selon l'invention peut, bien entendu avec quelques modifications, s'adapter au motocyclettes et éventuellement aux habitations. The device according to the invention can, of course with a few modifications, adapt to motorcycles and possibly to homes.
