Description

DISPOSITIF ANTI-VOL POUR VEHICULE ANTI-THEFT DEVICE FOR VEHICLE
Domaine techniqueTechnical area
La présente invention concerne un dispositif perfec¬ tionné pour protéger un véhicule contre le vol.The present invention relates to a perfected device for protecting a vehicle against theft.
Technique antérieurePrior art
Outre les systèmes d'alarme prévus pour produire un signal sonore en cas de tentative d'effraction, on con¬ naît un dispositif agencé pour couper l'allumage du moteur au bout d'un laps de temps prédéterminé, par exemple deux minutes, après qu'il ait été activé. Un tel dispositif implique que le conducteur d'un véhicule équipé du dispositif ait activé celui-ci.In addition to the alarm systems designed to produce an audible signal in the event of an attempted break-in, there is a device designed to cut off the ignition of the engine after a predetermined period of time, for example two minutes, after that it has been activated. Such a device implies that the driver of a vehicle equipped with the device has activated it.
Or, il est des agressions violentes qui empêchent le conducteur d'activer un dispositif de ce genre. En effet, si le conducteur se trouve dans un état de choc et n'a pas la présence d'esprit ou le temps d'activer le dispositif, par exemple lorsqu'il est arraché ou chassé brutalement de son siège (car-jacking) , ce genre de dispositif ne peut être activé et est dès lors in¬ efficace. Même doté d'une télécommande, un tel dispositif ne peut être activé en cas d'agression du conducteur si celui- ci n'a pas eu le temps de reprendre ses esprits et d'actionner la télécommande avant que son véhicule n'ait disparu hors de portée de la télécommande.However, there are violent assaults which prevent the driver from activating a device of this kind. Indeed, if the driver is in a state of shock and does not have the presence of mind or the time to activate the device, for example when he is torn off or brutally driven from his seat (car-jacking) , this kind of device cannot be activated and is therefore in¬ efficient. Even with a remote control, such a device cannot be activated in the event of aggression by the driver if he has not had time to regain consciousness and activate the remote control before his vehicle has disappeared out of range of the remote control.
Exposé de l'inventionStatement of the invention
Le but de la présente invention est d'empêcher qu'un véhicule faisant l'objet d'une tentative de vol ne puisse disparaître dans le trafic lorsque le conduc¬ teur a quitté son véhicule, volontairement ou par le fait d'une agression.The object of the present invention is to prevent a vehicle which is the subject of an attempted theft from being able to disappear in traffic when the driver has left his vehicle, voluntarily or by the act of an assault.
Pour atteindre ce but l'invention propose un dispo¬ sitif anti-vol tel que défini dans les revendications. En particulier, un contact est disposé dans le siège du conducteur du véhicule de manière à être actionné par le poids du conducteur prenant place sur le siège. Un premier moyen de commutation est connecté pour se trou¬ ver actionné en réponse à la venue en position travail du contact de siège précité, ledit moyen de commutation étant agencé pour immobiliser le véhicule après un laps de temps prédéterminé. Un deuxième moyen de commutation peut être connecté pour se trouver actionné en réponse à la venue en position travail du contact de siège pré¬ cité et pour actionner le premier moyen de commutation après une première période de temps prédéterminée.To achieve this object, the invention provides an anti-theft device as defined in the claims. In particular, a contact is arranged in the driver's seat of the vehicle so as to be actuated by the weight of the driver taking place on the seat. A first switching means is connected to be actuated in response to the aforementioned seat contact coming into the working position, said switching means being arranged to immobilize the vehicle after a predetermined period of time. A second switching means can be connected to be actuated in response to the arrival in the working position of the aforementioned seat contact and to actuate the first switching means after a first predetermined period of time.
Grâce à l'invention, un véhicule se trouve immobilisé automatiquement dans un rayon de quelques kilomètres de l'endroit où un conducteur non autorisé s'est emparé du véhicule. Même lorsque le conducteur habituel d'un vé¬ hicule est l'objet d'une agression et est chassé ou ar¬ raché de son siège (car-jacking) , il lui est possible, sitôt qu'il est soustrait à la menace de l'agresseur et a repris ses esprits, d'alerter la police qui n'aura alors aucune peine pour retrouver le véhicule immobi¬ lisé à peu de distance.Thanks to the invention, a vehicle is immobilized automatically within a radius of a few kilometers from the place where an unauthorized driver has taken the vehicle. Even when the usual driver of a vehicle is the object of an assault and is chased or removed from his seat (car-jacking), it is possible for him, as soon as he is removed from the threat of the attacker and regained his senses, to alert the police, who will then have no trouble finding the immobilized vehicle a short distance away.
Le dispositif selon l'invention peut être aisément com¬ biné avec divers moyens d'alerte ou de protection sup¬ plémentaires ainsi qu'il ressortira de la description qui suit, accompagnée de dessins.The device according to the invention can be easily combined with various additional alert or protection means as will emerge from the description which follows, accompanied by drawings.
Brève description des dessinsBrief description of the drawings
La figure 1 est un schéma simplifié d'un exemple de réalisation de l'invention. La figure 2 est un schéma simplifié d'une variante du mode de réalisation de la figure 1, utilisant une té¬ lécommande.Figure 1 is a simplified diagram of an exemplary embodiment of the invention. Figure 2 is a simplified diagram of a variant of the embodiment of Figure 1, using a remote control.
Exemple de réalisation de l'inventionExample of embodiment of the invention
Le dispositif selon l'invention est développé autour d'un contact agencé sous le siège du conducteur du véhicule de manière à se trouver actionné sous le poids du conducteur. La figure 1 représente le schéma du cir¬ cuit dans lequel est inséré le contact de siège 11. Lorsqu'aucun conducteur n'est installé sur le siège équipé du contact de siège 11, celui-ci est ouvert et le dispositif est au repos. Ce contact 11 ne se ferme que lorsqu'un conducteur s'y trouve installé.The device according to the invention is developed around a contact arranged under the seat of the driver of the vehicle so as to be actuated under the weight of the driver. FIG. 1 represents the diagram of the cooked circuit in which the seat contact 11 is inserted. When no conductor is installed on the seat equipped with the seat contact 11, it is open and the device is at rest. This contact 11 closes only when a conductor is installed there.
Un tel contact de siège a certes déjà été proposé par GB-A-2201820, mais uniquement pour actionner un dispo¬ sitif d'alarme afin d'alerter le voisinage de la pré¬ sence d'un intrus sur le siège du conducteur. Dans ce cas, le contact de siège fait simplement partie d'un système d'alarme et n'empêche nullement le départ du véhicule.Such a seat contact has certainly already been proposed by GB-A-2201820, but only to activate an alarm device in order to alert the neighborhood of the presence of an intruder on the driver's seat. In this case, the seat contact is simply part of an alarm system and does not prevent the vehicle from leaving.
Conformément à l'invention, le contact de siège 11 n'est pas utilisé pour produire un signal d'alerte, mais pour empêcher la disparition du véhicule et plus particulièrement pour immobiliser le véhicule après un laps de temps court prédéterminé lorsqu'un conducteur non autorisé s'est emparé du véhicule, même en en dé¬ tenant ou en en ayant dérobé les clés.According to the invention, the seat contact 11 is not used to produce an alert signal, but to prevent the disappearance of the vehicle and more particularly to immobilize the vehicle after a predetermined short period of time when a driver is not authorized person took possession of the vehicle, even if he held it or stole the keys.
En bref, le contact de siège 11 est connecté à un dis¬ positif de commutation au moins, notamment le commuta¬ teur 16 constitué par exemple d'un relais temporisé multicontact, agencé pour assurer l'immobilisation du véhicule au bout d'un laps de temps prédétemriné après la fermeture du contact de siège 11.In short, the seat contact 11 is connected to at least one switching device, in particular the switch 16 consisting for example of a multi-contact time relay, arranged to immobilize the vehicle after a lapse of time. predetermined time after closing the seat contact 11.
Dans l'exemple de réalisation décrit ici, le laps de temps précité se décompose en deux périodes successi- ves. Plus particulièrement, sur la figure 1 la fermetu¬ re du contact de siège 11 alimente un relais temporisé 12 qui, après une première période de temps prédétermi- née (préréglée au garage, par exemple sur 20 secondes) , alimente un vibreur sonore (buzzer) 13, à tonalité constante ou intermittente (bip-bip-bip) . Le vibreur sonore retentit dans l'habitacle du véhicule, avertis- sant le conducteur qu'il doit appuyer sur un bouton- poussoir 14 caché à un endroit bien dissimulé (ce peut être un contact de proximité placé sous le tapis de sol ou dans le siège) . En parallèle sur le vibreur sonore se trouve connecté l'enroulement d'excitation du relais temporisé 16, qui est aussi préréglé au garage, par exemple sur une période de temporisation de 15 secondes.In the embodiment described here, the aforementioned period of time breaks down into two successive periods. More particularly, in FIG. 1, the closure of the seat contact 11 supplies a time relay 12 which, after a first predetermined period of time, born (preset in the garage, for example for 20 seconds), supplies a buzzer 13, with constant or intermittent tone (beep-beep-beep). The buzzer sounds in the passenger compartment of the vehicle, warning the driver that he must press a hidden push button 14 in a well concealed place (this can be a proximity switch placed under the floor mat or in the seat) . In parallel to the buzzer is connected the excitation winding of the time relay 16, which is also preset in the garage, for example over a time period of 15 seconds.
Si c'est le conducteur habituel qui est au volant, il connaît l'emplacement du bouton-poussoir 14 et il peut donc le manoeuvrer dans le temps imparti fixé par la période de temporisation du relais temporisé 12, ce qui met fin au cycle de travail (jusqu'au moment où il s'assiéra à nouveau sur son siège après un arrêt) . L'action du bouton-poussoir 14 excite la bobine d'un relais simple 15, muni de deux contacts (un normalement ouvert 15A et un normalement fermé 15B) . Un des con¬ tacts sert de contact de maintien, tandis que l'autre, qui était fermé au départ, s'ouvre et coupe ainsi l'alimentation du vibreur sonore 13 et l'enroulement du relais 16. Lorsque le conducteur quitte son siège, le contact de siège 11 s'ouvre à nouveau, coupant ainsi l'alimentation des relais 12 et 15, ce qui les ramène à l'état initial.If it is the usual driver who is behind the wheel, he knows the location of the push button 14 and can therefore operate it within the allotted time fixed by the time delay period of the time relay 12, which ends the cycle of work (until he sits back in his seat after a stop). The action of the push button 14 excites the coil of a simple relay 15, provided with two contacts (one normally open 15A and one normally closed 15B). One of the contacts serves as a holding contact, while the other, which was closed at the start, opens and thus cuts off the power to the buzzer 13 and the winding of the relay 16. When the driver leaves his seat , the seat contact 11 opens again, thereby cutting off the power to the relays 12 and 15, which brings them back to the initial state.
Lorsqu'une personne non autorisée s'installe au volant et si elle ne réussit pas à appuyer sur le bouton- poussoir dans le temps imparti fixé par la temporisa¬ tion du relais temporisé 16 (15 secondes dans l'exemple choisi) , celui-ci se trouve activé, ce qui déclenche toutes les actions commandées par les contacts 16A, 16B, etc. , suivant la position qui aura été préala¬ blement déterminée au garage lors de l'installation.When an unauthorized person gets behind the wheel and if he does not succeed in pressing the push button within the allotted time set by the time delay of the time relay 16 (15 seconds in the example chosen), this- this is activated, which triggers all actions controlled by contacts 16A, 16B, etc. , depending on the position which has been previously determined in the garage during installation.
Sur la figure 1, le relais temporisé 16 est prévu avec des contacts multiples, par exemple deux contacts du type A, qui s'ouvrent à la fin du délai préréglé, pour couper le circuit d'allumage de la voiture et le cir¬ cuit d'alimentation de la pompe à carburant, et plu- sieurs contacts, du type B qui se ferment à la fin du délai préréglé, pour actionner des organes divers : klaxon, feux clignotants, une sirène, le verrouillage des portières et des fenêtres, éventuellement une bombe lacrymogène, un airbag, etc. Le véhicule se trouve ain- si immobilisé dès que le relais temporisé 16 a été ac¬ tionné, c'est-à-dire à la fin d'un laps de temps pré¬ déterminé réglable après que le contact de siège 11 a été actionné. Même après avoir chassé ou arraché le conducteur de son siège (car-jacking) , le voleur ne pourra aller loin avec le véhicule volé car celui-ci se trouve immobilisé après un très court laps de temps.In FIG. 1, the time relay 16 is provided with multiple contacts, for example two contacts of type A, which open at the end of the preset delay, to cut off the ignition circuit of the car and the circuit. fuel pump supply, and several contacts, type B which close at the end of the preset time, to activate various components: horn, flashing lights, siren, door and window locks, possibly a tear gas canister, an airbag, etc. The vehicle is thus immobilized as soon as the time relay 16 has been actuated, that is to say at the end of a pre-determined period of time adjustable after the seat contact 11 has been actuated . Even after chasing or ripping the driver from his seat (car jacking), the thief cannot go far with the stolen vehicle because it is immobilized after a very short period of time.
La séquence des états des différents organes de commu¬ tation du circuit de la figure 1 est résumée dans les tableaux 1 et 2, respectivement dans le cas où le conducteur autorisé est au volant et dans le cas où c'est une personne non autorisée qui s'installe sur le siège du conducteur.The sequence of states of the various switching bodies of the circuit in FIG. 1 is summarized in Tables 1 and 2, respectively in the case where the authorized driver is driving and in the case where it is an unauthorized person who installs in the driver's seat.

Il est à remarquer que le relais temporisé 16 à multi¬ ples contacts peut être remplacé par un relais tempori¬ sé à contact simple qui alimente alors les enroulements d'autres relais, ordinaires ou temporises, ce qui per- met d'établir une gradation dans l'escalade des actions envisagées. It should be noted that the time relay 16 with multiple contacts can be replaced by a single contact time relay which then supplies the windings of other relays, ordinary or timed, which allows a gradation to be established. in the escalation of the actions envisaged.
La figure 2 illustre une variante du circuit de la fi¬ gure 1, grâce à laquelle le conducteur habituel ne doit pas appuyer sur un bouton-poussoir après chaque démar¬ rage. A cet effet, un récepteur 18 remplace le relaisFIG. 2 illustrates a variant of the circuit of FIG. 1, whereby the usual driver does not have to press a push button after each start. For this purpose, a receiver 18 replaces the relay
15 de la figure 1 pour recevoir un signal de télécom¬ mande qu'émet un petit émetteur 19 que le conducteur peut porter sur lui (en poche ou en sautoir) . L'émet- teur de puissance très réduite (par exemple, un oscil¬ lateur à quartz) , rayonne en permanence un signal de fréquence bien déterminée.15 of Figure 1 to receive a telecom¬ command signal emitted by a small transmitter 19 that the driver can carry on him (pocket or jumper). The very reduced power transmitter (for example, a quartz oscillator) permanently radiates a signal of well-defined frequency.
Lorsque le contact de siège 11 se ferme sous le poids d'un conducteur, le relais temporisé 12 se trouve exci¬ té. Après une période de temps fixée par la temporisa¬ tion du relais temporisé 12, le contact de ce dernier se ferme et alimente l'enroulement du relais temporiséWhen the seat contact 11 closes under the weight of a driver, the time relay 12 is exci¬ ted. After a period of time fixed by the time delay of the time relay 12, the contact of the latter closes and supplies the winding of the time relay
16 comme dans la version de la figure 1. En outre, comme les deux bornes du contact du relais temporisé 12 sont à ce moment au même potentiel, le récepteur 18, est averti qu'il doit vérifier la présence d'un signal émis par l'émetteur 19.16 as in the version of FIG. 1. In addition, since the two terminals of the contact of the time relay 12 are at this moment at the same potential, the receiver 18 is warned that it must verify the presence of a signal emitted by the transmitter 19.
Le circuit de sortie du récepteur 18 est constitué d'un relais qui remplit la fonction du relais 15 de la figu¬ re 1, à savoir couper l'alimentation de l'enroulement du relais temporisé 16, dans le cas et seulement dans le cas où il reçoit un signal émis par l'émetteur 19 porté par le conducteur autorisé. Par conséquent, si c'est le conducteur habituel qui est au volant, le dis¬ positif met fin au cycle de travail (jusqu'au moment où il s'assiéra à nouveau sur son siège après un arrêt) .The output circuit of the receiver 18 consists of a relay which fulfills the function of the relay 15 of FIG. 1, namely cutting off the supply to the winding of the timed relay 16, in the case and only in the case where it receives a signal emitted by the transmitter 19 carried by the authorized driver. Therefore, if it is the usual driver who is behind the wheel, the device ends the work cycle (until he sits down again in his seat after a stop).
Faute de reconnaître le signal de l'émetteur 19 propre au conducteur habituel, le récepteur continue à laisser passer le courant dans son relais de sortie et par le contact du relais temporisé 12, ce qui conduit à la venue au travail du relais temporisé 16 au terme de la période de temporisation préréglée, avec toutes les conséquences décrites précédemment. Dès lors, si c'est un intrus qui est au volant, à la fin de la période de temporisation du relais 16, le dispositif commande toutes les actions contrôlées par les contacts 16A, 16B, ... du relais temporisé 16 suivant la position qui aura été préalablement déterminée au garage lors de l'installation. Le véhicule se trouve ainsi immobilisé dès que le relais temporisé 16 a été actionné, c'est-à- dire après un laps de temps prédéterminé réglable à partir du moment où le contact de siège 11 a été ac¬ tionné.Failing to recognize the signal from the transmitter 19 specific to the usual driver, the receiver continues to let current flow through its output relay and by contacting the time relay 12, which leads to the coming to work of the time relay 16 at end of the preset delay period, with all the consequences described above. Therefore, if it is an intruder who is driving, at the end of the delay period for relay 16, the device controls all the actions controlled by the contacts 16A, 16B, ... of the time relay 16 according to the position which will have been previously determined at the garage during installation. The vehicle is thus immobilized as soon as the time relay 16 has been actuated, that is to say after a predetermined period of time adjustable from the moment when the seat contact 11 has been actuated.
La séquence des états des différents organes de com¬ mutation dans le circuit de la figure 2 est résumée dans les tableaux 3 et 4, respectivement dans le cas où le conducteur autorisé est au volant et dans le cas où c'est une personne non autorisée qui s'installe sur le siège du conducteur.The sequence of states of the various switching bodies in the circuit of FIG. 2 is summarized in Tables 3 and 4, respectively in the case where the authorized driver is behind the wheel and in the case where it is an unauthorized person. which is installed in the driver's seat.

Les versions manuelle et automatique représentées dans les figures 1 et 2 sont des versions mettant en oeuvre des relais électro-magnétiques, dont le fonctionnement se prête bien à une description détaillée. Il va de soi pour l'homme du métier que les relais temporises peu¬ vent être remplacés par des relais à excitation retar- dée ou tout autre dispositif ou circuit électronique assurant les mêmes fonctions, de manière à obtenir les séquences d'actions requises alors que le véhicule est piloté par son conducteur habituel ou par une personne non autorisée.The manual and automatic versions represented in FIGS. 1 and 2 are versions using electromagnetic relays, the operation of which lends itself well to a detailed description. It goes without saying for those skilled in the art that the timed relays can be replaced by relays with delayed excitation. or any other electronic device or circuit ensuring the same functions, so as to obtain the required action sequences while the vehicle is driven by its usual driver or by an unauthorized person.
Dans la version automatique, le conducteur habituel doit avoir en poche ou porter en sautoir un petit émet¬ teur lui permettant d'être "reconnu" par le récepteur chargé de couper l'alimentation de l'enroulement du relais 16 après la fermeture du contact du relais temporisé 12.In the automatic version, the usual driver must have in his pocket or carry in a jumper a small transmitter allowing him to be "recognized" by the receiver responsible for cutting the supply to the winding of the relay 16 after closing the contact of the time relay 12.
Comme cet émetteur doit émettre son signal pendant tout le temps que le conducteur habituel est au volant, il vaut mieux qu'il fonctionne en permanence, car s'il de¬ vait être mis en service chaque fois que le conducteur habituel prend le volant, on retomberait dans la sujé¬ tion déplorée dans la version manuelle, qui demande une pression sur un bouton-poussoir chaque fois que le buzzer retentit, soit après chaque nouvelle installa¬ tion sur le siège. Cette sujétion peut entraîner une usure rapide de la pile alimentant le petit émetteur.As this transmitter must transmit its signal during the entire time that the usual driver is behind the wheel, it is better for it to operate continuously, because if it had to be put into service each time the usual driver takes the wheel, we would fall back into the subject deplored in the manual version, which requires a press on a push button each time the buzzer sounds, or after each new installation on the seat. This subjection can lead to rapid wear of the battery supplying the small transmitter.
Pour échapper à cette contrainte, il suffit d'installer dans un même boîtier, l'émetteur requis dans la version automatique du dispositif et la télécommande du ver¬ rouillage des portières. Dans ce boîtier unique, une connexion peut être prévue pour que l'émetteur ne soit alimenté qu'à partir du moment où le conducteur habi¬ tuel télécommande l'ouverture des portières et que cette alimentation soit coupée quand il télécommande la fermeture des portières. Ce boîtier ne doit évidemment pas être attaché au trousseau de clés, ce qui équivaudrait à coller sur une carte de banque une étiquette indiquant le numéro de code qui y est associé. Au trousseau de clés, on ne peut attacher qu'un boîtier de télécommande classique afin de mettre en confiance un voleur éventuel et ser¬ vir au conducteur habituel en cas de panne du boîtier qu'il porte en poche, car il peut ainsi monter en voi¬ ture, neutraliser les interrupteurs 16A, 16B, etc. , et démarrer.To escape this constraint, it suffices to install in the same housing, the transmitter required in the automatic version of the device and the remote control for the door lock. In this single box, a connection can be provided so that the transmitter is only supplied with power as soon as the usual driver remote controls the opening of the doors and this supply is cut off when he controls the closing of the doors. This box must obviously not be attached to the key ring, which would be equivalent to sticking a label on a bank card indicating the code number associated with it. Only a conventional remote control unit can be attached to the keyring in order to gain the confidence of a potential thief and serve the usual driver in the event of a failure of the unit he is carrying in his pocket, because he can thus climb up car, neutralize switches 16A, 16B, etc. , and start.
De toute façon, la version automatique peut toujours inclure un relais et un bouton-poussoir pour permettre une utilisation manuelle, même sans buzzer.Anyway, the automatic version can always include a relay and a push button to allow manual use, even without a buzzer.
Aux actions prévues ci-dessus peuvent s'en ajouter d'autres. Par exemple, pour les voitures équipées d'un mobilophone, un contact peut être prévu sur le relais 16 pour établir un circuit qui prend la ligne, appelle le numéro d'appel de la police préalablement mis en mémoire et envoie un message préenregistré (sur micro¬ cassette ou sur puce) signalant le vol, par exemple : "Appel à toutes les polices ! Ce message est émis au¬ tomatiquement de la voiture de marque X couleur Y N° Z qui vient d'être volée ! Prière de l'intercepter ! Attention ! Un homme dangereux est à son volant !".To the actions provided above can be added others. For example, for cars equipped with a mobile phone, a contact can be provided on relay 16 to establish a circuit which takes the line, calls the telephone number of the police previously stored and sends a pre-recorded message (on micro¬ cassette or on chip) signaling the theft, for example: "Call to all police! This message is sent automatically from the X brand car YN ° Z color which has just been stolen! Please intercept it ! Warning! A dangerous man is behind the wheel! ".
Il est également possible, par exemple, d'installer un mini-revolver à gâchette électrique dans l'appui-tête ou le dossier pour tirer une balle ou une fléchette par exemple contenant un anesthésique comme celui qui est utilisé pour la capture des animaux féroces.It is also possible, for example, to install a mini-revolver with an electric trigger in the headrest or the backrest to shoot a ball or a dart, for example containing an anesthetic such as that used to capture ferocious animals .
