Abstract

The system includes a supply (E) provided by a battery (B) and an alternator (A) connected in parallel. They supply power to a card reader (L) into which a card (C) is inserted, and to the other electrical circuits of the vehicle. The circuit is simplified to three branches (B1,B2,B3), the first of which (B1) includes the ignition and starter circuits. The second branch includes an alarm, and the third branch includes instruments on the vehicle dashboard. When a card is inserted and read, a signal is sent to all three circuits. If the card is valid the user may start the vehicle. If the card is invalid, different signals are produced and the alarm is activated.

Description

Véhicule automobile à système de protection vis-à-vis du vol à carte à puce
La présente invention concerne des véhicules automobiles comportant un système de protection vis-à-vis du vol à carte à puce.Motor vehicle with chip card theft protection system
The present invention relates to motor vehicles comprising a protection system against theft by smart card.

Un véhicule automobile peut comporter un système de protection, telle qu'une alarme. Le circuit d'alarme, alimenté par la batterie du véhicule, est surajouté au circuit électrique principal d'allumage-démarrage du véhicule. I1 peut ainsi être trouvé facilement et débranché par un voleur. D'autre part, l'alarme n'interdit pas de mettre le véhicule en marche, et de le voler malgré ce signal d'alarme. A motor vehicle may include a protection system, such as an alarm. The alarm circuit, powered by the vehicle's battery, is added to the vehicle's main ignition-start electrical circuit. It can thus be easily found and disconnected by a thief. On the other hand, the alarm does not prohibit starting the vehicle, and stealing it despite this alarm signal.

I1 existe également des systèmes de protection tels que les clés à code. Le propriétaire du véhicule insère la clé de contact et entre en même temps un code qui débloque un interrupteur électro-mécanique manoeuvré par la clé. Il suffit au voleur de court-circuiter l'interrupteur pour voler le véhicule. There are also protection systems such as code keys. The vehicle owner inserts the ignition key and at the same time enters a code that unlocks an electro-mechanical switch operated by the key. The thief only has to short-circuit the switch to steal the vehicle.

L'invention vise un véhicule automobile comprenant un système de protection plus sûr que le système antérieur. The invention relates to a motor vehicle comprising a more secure protection system than the prior system.

Le véhicule automobile suivant l'invention comporte un circuit électrique d'allumage-démarrage ou circuit principal ainsi qu'un lecteur de carte à puce destiné à envoyer un signal quand une carte y est insérée et qu'un module monté dans le circuit électrique de manière à agir d'une façon si le signal envoyé est celui prescrit et d'une autre façon si ce signal n'est pas celui prescrit. The motor vehicle according to the invention comprises an electrical ignition-start circuit or main circuit as well as a chip card reader intended to send a signal when a card is inserted therein and a module mounted in the electrical circuit of so as to act in one way if the signal sent is that prescribed and in another way if this signal is not that prescribed.

Comme il n'y a plus un circuit de protection indépendant du circuit principal, notamment monté en parallèle avec celui-ci, et donc facile à identifier ou à trouver et à débrancher ou à court-circuiter, et comme, de plus, le module peut être monté à n'importe quel point du circuit principal, avec d'ailleurs la possibilité de prévoir plusieurs modules, et comme, de surcrolt, le module est constitué de composants de même nature que ceux du circuit principal, il est très difficile à localiser. Pratiquement, le voleur est obligé, soit de démonter tout le circuit principal du véhicule et de trouver le module, de le courtcircuiter et de remonter tout le circuit principal, ce qui est très difficile et très long, soit de créer un autre circuit principal en parallèle de celui déjà existant, ce qui est, sans le matériel nécessaire, pratiquement impossible. As there is no longer a protection circuit independent of the main circuit, especially mounted in parallel with it, and therefore easy to identify or find and disconnect or short-circuit, and like, moreover, the module can be mounted at any point on the main circuit, with the possibility of providing several modules, and since, on top, the module is made up of components of the same kind as those of the main circuit, it is very difficult to locate. In practice, the thief is obliged either to dismantle the entire main circuit of the vehicle and find the module, to short-circuit it and reassemble the entire main circuit, which is very difficult and very long, or to create another main circuit by parallel to the already existing one, which is practically impossible without the necessary equipment.

D'autre part, comme on utilise le circuit principal déjà existant du véhicule, l'installation du système de protection est facile et peu coûteuse. On the other hand, as the already existing main circuit of the vehicle is used, the installation of the protection system is easy and inexpensive.

Le module peut être agencé de manière à ouvrir ledit circuit électrique si le signal envoyé n'est pas celui prescrit et à le fermer si le signal envoyé est celui prescrit. Dans le premier cas, le circuit électrique d'allumage-démarrage n'est plus alimenté et le véhicule est bloqué. The module can be arranged so as to open said electrical circuit if the signal sent is not that prescribed and to close it if the signal sent is that prescribed. In the first case, the electrical ignition-start circuit is no longer supplied and the vehicle is blocked.

Le module peut également être agencé de manière à envoyer un signal d'alerte si le signal envoyé n'est pas celui prescrit, de sorte que son propriétaire peut être informé de la tentative de vol de son véhicule, sans que le voleur ne puisse interrompre le signal d'alerte. The module can also be arranged so as to send an alert signal if the signal sent is not that prescribed, so that its owner can be informed of the attempted theft of his vehicle, without the thief being able to interrupt the alert signal.

Au dessin annexé, donné uniquement à titre d'exemple
L'unique figure représente un schéma simplifié du réseau électrique d'un véhicule suivant l'invention.In the accompanying drawing, given only by way of example
The single figure represents a simplified diagram of the electrical network of a vehicle according to the invention.

Ce réseau électrique comporte, à la manière classique, une alimentation E constituée, essentiellement, d'une batterie B et d'un alternateur A, qui sont reliés en parallèle, d'une part, à un lecteur L muni d'une carte C, et d'autre part, à différentes branches du circuit électrique du véhicule. En vue de simplifier, on a représenté à la figure uniquement trois types de branches de circuit B1, B2 et B3. This electrical network comprises, in the conventional manner, a power supply E essentially consisting of a battery B and an alternator A, which are connected in parallel, on the one hand, to a reader L provided with a card C , and on the other hand, to different branches of the vehicle's electrical circuit. For the sake of simplicity, only three types of circuit branches B1, B2 and B3 have been shown in the figure.

La première branche de circuit B1 comporte un premier circuit électrique C1 du véhicule tel que le circuit d'allumagedémarrage, qui est relié à un premier module M1 qui, lui, est relié à la sortie d'un interrupteur I1 faisant office de clé, l'entrée de l'interrupteur I1 étant reliée à la batterie E.The first branch of circuit B1 comprises a first electrical circuit C1 of the vehicle such as the starter ignition circuit, which is connected to a first module M1 which, for its part, is connected to the output of a switch I1 acting as a key, l input of switch I1 being connected to battery E.

Le lecteur L est branché soit en amont de l'interrupteur I1 par le conducteur a, soit en aval de l'interrupteur I1 par l'intermédiaire du conducteur b. La deuxième branche B2 est constituée d'un deuxième circuit électrique C2 du véhicule, qui peut être ici un circuit d'alarme, et qui est relié à un deuxième module M2 qui, lui, est relié d'une part à l'alimentation électrique E et d'autre part au lecteur L. La troisième branche B3 comporte un instrument de mesure C3, qui est relié à un troisième module M3. Ce module M3 est relié, d'une part, à la fois à l'alimentation électrique E et au lecteur L et, d'autre part, à un tableau de bord T qui est relié à l'alimentation électrique E.The reader L is connected either upstream of the switch I1 by the conductor a, or downstream of the switch I1 via the conductor b. The second branch B2 consists of a second electrical circuit C2 of the vehicle, which can here be an alarm circuit, and which is connected to a second module M2 which, on the other hand, is connected to the electrical supply E and on the other hand to the reader L. The third branch B3 comprises a measuring instrument C3, which is connected to a third module M3. This module M3 is connected, on the one hand, to both the power supply E and to the reader L and, on the other hand, to a dashboard T which is connected to the power supply E.

Lorsque l'utilisateur introduit sa carte C dans le lecteur L, ce dernier l'identifie. Si cette carte C est la bonne, le lecteur envoie un signal prescrit aux branches B1,
B2 et B3, de telle sorte que les modules M1, M2 et M3 sont transparents, c'est-à-dire qu'ils forment un circuit fermé, et tout le réseau électrique du véhicule est alimenté normalement. L'utilisateur peut ainsi faire démarrer le véhicule. When the user inserts his card C into the reader L, the latter identifies him. If this card C is the right one, the reader sends a prescribed signal to branches B1,
B2 and B3, so that the modules M1, M2 and M3 are transparent, that is to say that they form a closed circuit, and the entire electrical network of the vehicle is supplied normally. The user can thus start the vehicle.

Si, en revanche, la carte C introduite n'est pas la bonne, le lecteur L envoie aux branches B1, B2 et B3 un signal qui n'est pas celui prescrit et qui provoque une action adéquate des modules M1, M2 et M3. If, on the other hand, the card C inserted is not the correct one, the reader L sends to the branches B1, B2 and B3 a signal which is not that prescribed and which causes an adequate action of the modules M1, M2 and M3.

Dans le cas le plus simple, c'est-à-dire lorsqu'uniquement la première branche B1 est munie du premier module M1, ce dernier se comporte, par exemple, comme un interrupteur ouvert et le circuit d'allumage-démarrage C1 n'est plus alimenté. La personne qui a utilisé la mauvaise carte ne pourra pas faire démarrer le véhicule en utilisant la clé I1 puisque le circuit est ouvert indépendamment de l'action de cette clé. In the simplest case, that is to say when only the first branch B1 is provided with the first module M1, the latter behaves, for example, like an open switch and the ignition-start circuit C1 n is more fueled. The person who used the wrong card will not be able to start the vehicle using the key I1 since the circuit is open regardless of the action of this key.

Si, en supplément, la deuxième branche B2 est munie du deuxième module M2, ce dernier reçoit un signal du lecteur
L et le transmet au circuit d'alarme C2 qui envoie un signal d'alarme.If, in addition, the second branch B2 is provided with the second module M2, the latter receives a signal from the reader
L and transmits it to the alarm circuit C2 which sends an alarm signal.

Enfin, si l'on prévoit un troisième module M3 dans la troisième branche B3, ce module reçoit un signal du lecteur L et le transmet à l'instrument de mesure C3 qui se place en position de mesure. Si le voleur déplace le véhicule, en le poussant par exemple, un faible courant correspondant au signal envoyé à un des instruments de mesure du tableau de bord T passe dans la troisième branche B3. Finally, if a third module M3 is provided in the third branch B3, this module receives a signal from the reader L and transmits it to the measuring instrument C3 which is placed in the measuring position. If the thief moves the vehicle, for example by pushing it, a weak current corresponding to the signal sent to one of the measuring instruments of the dashboard T passes into the third branch B3.

L'instrument de mesure le détecte par l'intermédiaire du troisième module M3 qui déclenche un signal d'alarme, ou qui envoie un signal de détection au lecteur L. Dans ce dernier cas, le lecteur L envoie alors, par exemple, une commande de signal d'alarme par l'intermédiaire de la branche B2. The measuring instrument detects it via the third module M3 which triggers an alarm signal, or which sends a detection signal to the reader L. In the latter case, the reader L then sends, for example, a command alarm signal via branch B2.
