Description

Dispositif de communication pour véhicule automobileCommunication device for a motor vehicle

L'invention se rapporte à un dispositif de communication pour véhicule automobile et en particulier à un tel dispositif utilisé pour le tracking.  The invention relates to a communication device for a motor vehicle and in particular to such a device used for tracking.

Le mot anglais tracking est communément utilisé pour désigner les systèmes de surveillance et d'alerte de véhicules volés. Un système de tracking comporte généralement un système d'alarme classique et un dispositif de communication couplé à un réseau de bornes ou de satellites. Grâce à un tel lo système, il est ainsi possible de détecter et localiser un objet, par exemple un véhicule automobile, lorsqu'il se trouve dans la zone de couverture d'un desdits réseaux.  The English word tracking is commonly used to designate the surveillance and alert systems of stolen vehicles. A tracking system generally comprises a conventional alarm system and a communication device coupled to a network of terminals or satellites. With such a lo system, it is thus possible to detect and locate an object, for example a motor vehicle, when it is in the coverage area of one of said networks.

Dans le cas particulier d'un véhicule automobile, les systèmes de communication sont gênés par ses parties métalliques telles que la carrosserie ou la structure. En effet, ces parties métalliques atténuent fortement les ondes électromagnétiques en diminuant ainsi considérablement les signaux reçus par le véhicule. C'est pourquoi, les antennes d'émission et de réception du véhicule telles que les antennes GSM/GPS (Galiléo) sont généralement à l'extérieur de la carrosserie. Ce critère d'intégration des antennes est très pénalisant pour l'esthétique du véhicule et inopportun pour la dissimulation des antennes de tracking. En effet, l'antenne de tracking ne doit pas pouvoir être facilement localisée et/ou enlevée par l'éventuel malfaiteur.  In the particular case of a motor vehicle, the communication systems are hindered by its metal parts such as the body or the structure. Indeed, these metal parts strongly attenuate the electromagnetic waves thus considerably reducing the signals received by the vehicle. This is why the transmit and receive antennas of the vehicle such as GSM / GPS antennas (Galileo) are generally outside the bodywork. This criterion of integration of the antennas is very penalizing for the aesthetics of the vehicle and inconvenient for the dissimulation of the antennas of tracking. Indeed, the tracking antenna must not be easily located and / or removed by the possible perpetrator.

Le but de la présente invention est de pallier tout ou partie les inconvénients cités précédemment en proposant une antenne dissimulée dont l'émission et la réception ne sont pas affectées.  The object of the present invention is to overcome all or part of the disadvantages mentioned above by providing a concealed antenna whose transmission and reception are not affected.

A cet effet, l'invention se rapporte à un dispositif de communication pour véhicule automobile comportant une unité de gestion d'une antenne apte à émettre et recevoir des ondes électromagnétiques caractérisé en ce que ladite antenne et ladite unité de gestion sont solidaires du dispositif de stockage de carburant dudit véhicule automobile afin de permettre leur dissimulation tout en rendant leur retirement dudit dispositif de stockage de carburant difficile voire destructif. En effet, d'une part ce dernier est toujours constitué d'un matériau perméable aux ondes électromagnétiques et d'autre part, son démontage fait que le moteur ne peut plus être fourni en carburant.  For this purpose, the invention relates to a communication device for a motor vehicle comprising a management unit of an antenna capable of transmitting and receiving electromagnetic waves, characterized in that said antenna and said management unit are integral with the device. storing fuel of said motor vehicle to allow their concealment while making their removal from said fuel storage device difficult or even destructive. Indeed, on the one hand the latter is always made of a material permeable to electromagnetic waves and on the other hand, its disassembly is that the engine can no longer be supplied with fuel.

Conformément à d'autres caractéristiques avantageuses de l'invention: L'antenne est soit fixée sur la surface extérieure ou io intérieure dudit dispositif de stockage de carburant, soit moulée dans ledit dispositif de stockage de carburant. ; De la même manière, ladite unité de gestion est soit fixée sur la surface extérieure ou intérieure dudit dispositif de stockage de carburant, soit moulée dans ledit dispositif de stockage de carburant; Ladite antenne court de l'unité de gestion jusqu'à sensiblement l'extrémité de la goulotte dudit dispositif de stockage du carburant de façon à faire face sensiblement à la trappe à carburant. Cela permet d'émettre et recevoir des ondes électromagnétiques car la trappe à carburant est quasiment toujours en un matériau perméable à ces premières; Enfin, l'unité de gestion comporte une alimentation autonome en énergie ou est alimentée en énergie par le 25 réseau de bord dudit véhicule automobile.  According to other advantageous features of the invention: The antenna is either attached to the outer or inner surface of said fuel storage device, or molded into said fuel storage device. ; In the same way, said management unit is either fixed on the outer or inner surface of said fuel storage device, or molded into said fuel storage device; Said short antenna of the management unit to substantially the end of the chute of said fuel storage device so as to substantially face the fuel door. This makes it possible to emit and receive electromagnetic waves because the fuel filler flap is almost always made of a material permeable to these firsts; Finally, the management unit comprises an autonomous energy supply or is supplied with energy by the onboard network of said motor vehicle.

D'autres particularités et avantages ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés, dans lesquelles: la figure 1 est une vue en perspective d'un dispositif de stockage de carburant d'un véhicule automobile; les figures 2a et 2b sont deux sections schématiques présentant deux implantations possibles de l'antenne dans une goulotte.  Other features and advantages will become clear from the description which is given below, for information only and in no way limitative, with reference to the accompanying drawings, in which: FIG. 1 is a perspective view of a storage device of fuel of a motor vehicle; Figures 2a and 2b are two schematic sections with two possible locations of the antenna in a chute.

Dans l'exemple illustré à la figure 1, on peut voir une partie d'un véhicule automobile 1 et son dispositif de stockage de carburant associé 2.  In the example illustrated in Figure 1, we can see a part of a motor vehicle 1 and its associated fuel storage device 2.

Le côté de caisse 3 du véhicule automobile 1 comporte la carrosserie 4 qui, composée essentiellement de matériau métallique, sert de support pour la trappe à carburant 5 (on peut voir son recto à la figure 1). Cette dernière est généralement constituée de matière polymère et montée pivotante par rapport au côté de caisse 3. La trappe à carburant 5 est grâce à sa constitution en polymère perméable aux ondes électromagnétiques qu'elle soit en position ouverte ou fermée.  The body side 3 of the motor vehicle 1 comprises the body 4 which, consisting essentially of metallic material, serves as a support for the fuel door 5 (we can see its front in Figure 1). The latter is generally made of polymer material and pivotally mounted relative to the body side 3. The fuel door 5 is due to its constitution permeable polymer electromagnetic waves it is in the open or closed position.

Le dispositif de stockage de carburant 2 comporte un réservoir 6 pour stocker le carburant, une goulotte 7 en forme de cylindre coudé et une tubulure sensiblement infundibuliforme 8 qui permettent de remplir le réservoir 6. Ces trois moyens 6, 7 et 8 sont constitués de matériaux diélectriques, c'est-à-dire essentiellement du type isolant électrique, qui sont, tout comme la trappe à carburant 5, perméables aux ondes électromagnétiques. Comme représenté à la figure 1, la tubulure 8 fait face au verso quand la trappe à carburant 5 est fermée. Il comporte également un dispositif de communication généralement annoté 9 dans l'exemple illustré à la figure 1.  The fuel storage device 2 comprises a tank 6 for storing the fuel, a chute 7 in the form of an angled cylinder and a substantially infundibular pipe 8 which make it possible to fill the tank 6. These three means 6, 7 and 8 consist of materials dielectric, that is to say essentially of the electric insulator type, which are, like the fuel trap 5, permeable to electromagnetic waves. As shown in Figure 1, the tubing 8 faces the back when the fuel door 5 is closed. It also comprises a generally annotated communication device 9 in the example illustrated in FIG.

Le. dispositif de communication 9 comporte principalement une unité de gestion 10 et une antenne 11 reliée à cette première. L'implantation d'un dispositif de communication 9 utilisé pour le tracking est très importante. En effet, il doit être suffisamment dissimulé afin que, lors de la détection de vol ou d'effraction du véhicule automobile 1, la personne malveillante ne puisse pas rapidement le localiser et l'arracher en vue de l'empêcher d'émettre.  The. communication device 9 mainly comprises a management unit 10 and an antenna 11 connected to this first. The implementation of a communication device 9 used for tracking is very important. Indeed, it must be sufficiently concealed so that, during the detection of theft or burglary of the motor vehicle 1, the malicious person can not quickly locate and tear it to prevent it from issuing.

Préférentiellement selon l'invention, à ce principe de dissimulation est ajouté le principe de destructivité d'un organe essentiel du véhicule automobile en cas de retirement du dispositif de communication 9. De cette façon, si la personne malveillante peut déterminer où est localisé le dispositif de communication 9 et l'arracher, il rendra inutilisable le moteur du véhicule. Selon l'invention, l'organe essentiel est le dispositif de stockage de carburant 2.  Preferably, according to the invention, to this principle of dissimulation is added the principle of destructivity of an essential organ of the motor vehicle in the event of the communication device being stretched 9. In this way, if the malicious person can determine where the device is located communication 9 and tear it off, it will render unusable the engine of the vehicle. According to the invention, the essential organ is the fuel storage device 2.

Dans l'exemple illustré à la figure 1, l'unité de gestion 10 du dispositif de communication 9 est moulé sur le dessus du réservoir 6. Elle est donc montée entre le dessous de la carrosserie 4 et le réservoir 6. Cela permet de la rendre i0 difficilement visible même lorsque le véhicule automobile 1 est soulevé ou surélevé.  In the example illustrated in FIG. 1, the management unit 10 of the communication device 9 is molded on the top of the tank 6. It is therefore mounted between the underside of the bodywork 4 and the tank 6. This allows the make it difficult to see even when the motor vehicle 1 is raised or raised.

De la même manière, l'antenne 11, dans l'exemple illustré à la figure 1, est moulée dans la goulotte 7 et court jusqu'à la tubulure 8. Préférentiellement, l'antenne 11 est complètement recouverte de matière au niveau de la tubulure 8 afin que quiconque ouvrant la trappe à carburant 5 ne puisse pas voir ladite antenne saillir de la tubulure 8.  In the same way, the antenna 11, in the example illustrated in FIG. 1, is molded in the chute 7 and runs as far as the pipe 8. Preferably, the antenna 11 is completely covered with material at the level of the tubing 8 so that anyone opening the fuel door 5 can not see said antenna protruding from the tubing 8.

Les figures 2a et 2b permettent de voir un premier et deuxième exemple de section de la goulotte 7 selon la coupe A-A de la figure 1. Dans les deux exemples, la section sensiblement circulaire comporte un bourrelé 12 apte respectivement à entièrement recouvrir la section de l'antenne 11 (figure 2a) ou à contenir un canal destiné à recevoir la section de l'antenne 11 (figure 2b).  FIGS. 2a and 2b make it possible to see a first and second example of section of the chute 7 according to section AA of FIG. 1. In both examples, the substantially circular section comprises a stuffer 12 able respectively to completely cover the section of the antenna 11 (Figure 2a) or to contain a channel for receiving the section of the antenna 11 (Figure 2b).

Le principe d'une antenne 11 qui remonte jusqu'à la tubulure 8 permet une meilleure émission et réception du dispositif de communication 9. En effet du fait que la trappe à carburant 5 est perméable aux ondes électromagnétiques, les communications seront moins gênées par les surfaces métalliques de la carrosserie 4 qu'avec une antenne 11 seulement montée sur le réservoir 6.  The principle of an antenna 11 which goes up to the pipe 8 allows a better transmission and reception of the communication device 9. Indeed, because the fuel door 5 is permeable to electromagnetic waves, the communications will be less hampered by the metal surfaces of the bodywork 4 only with an antenna 11 mounted on the tank 6.

Dans le but d'améliorer la dissimulation du dispositif de communication 9, l'unité de gestion 10 est préférentiellement alimentée en énergie de manière autonome, c'est-à-dire par un accumulateur d'énergie électrique.  In order to improve the concealment of the communication device 9, the management unit 10 is preferably autonomously supplied with energy, that is to say by an accumulator of electrical energy.

Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art. En particulier, l'antenne 11 peut également être soit fixée sur la surface extérieure ou intérieure dudit dispositif de stockage de carburant. De plus, l'antenne 11 peut être uniquement moulée sur le réservoir 6. Egalement, l'unité de gestion 10 peut être io soit fixée sur la surface extérieure ou intérieure dudit dispositif de stockage de carburant. L'unité de gestion 10 peut être alimentée en énergie par le réseau de bord dudit véhicule automobile. Enfin, si le principe de destructivité est un mode préféré lors du retirement du dispositif de communication 9, le retirement en variante peut ne pas être destructif mais suffisamment contraignant et long pour que le dispositif de communication 9 émette le signal d'alerte.  Of course, the present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, the antenna 11 may also be attached to the outer or inner surface of said fuel storage device. In addition, the antenna 11 may be molded only on the tank 6. Also, the management unit 10 may be attached to the outer or inner surface of said fuel storage device. The management unit 10 can be supplied with energy by the onboard network of said motor vehicle. Finally, if the principle of destructivity is a preferred mode during the retraction of the communication device 9, the alternative stretch may not be destructive but sufficiently constraining and long for the communication device 9 to emit the warning signal.
