Description

La présente invention concerne un dispositif de verrouillage électronique pour un véhicule.The present invention relates to an electronic locking device for a vehicle.

PRESENTATION GENERALE DE L'ART ANTERIEURGENERAL PRESENTATION OF THE PRIOR ART

Il a déjà été proposé des dispositifs électroniques de verrouillage à distance pour véhicule.It has already been proposed electronic remote locking devices for vehicles.

Ce type de dispositif comprend des moyens de réception, des moyens de commande, et des moyens d'émission mobiles.This type of device comprises reception means, control means, and mobile transmission means.

Les moyens de réception permettent la réception d'un signal émis par les moyens d'émission. Les moyens de commande permettent l'actionnement du verrouillage du véhicule. Les moyens d'émission permettent l'émission d'un signal.The reception means allow reception of a signal transmitted by the transmitting means. The control means allow the activation of the vehicle lock. The transmitting means allow the emission of a signal.

On connaît des dispositifs électronique de verrouillage basé sur la condamnation du véhicule suite à la réception d'un signal de commande.Electronic locking devices are known based on the locking of the vehicle following the reception of a control signal.

Le principe de fonctionnement est le suivant. L'utilisateur actionne des moyens d'actionnement disposés sur les moyens d'émission pour commander le verrouillage du véhicule. Les moyens d'émission émettent un signal radiofréquence codé pour activer le verrouillage du véhicule. Les moyens de réception reçoivent le signal et le transmettent aux moyens de commande. Les moyens de commande décodent le signal reçu et activent le verrouillage du véhicule.The operating principle is as follows. The user actuates actuating means arranged on the transmission means for controlling the locking of the vehicle. The transmitting means emits a coded radio frequency signal to activate the locking of the vehicle. The receiving means receive the signal and transmit it to the control means. The control means decode the received signal and activate the locking of the vehicle.

La demande de brevet européen EP 0690190 divulgue un système pour verrouiller automatiquement un véhicule automobile lorsqu'un signal de commande est transmis par un module de clé. Les demandes internationales WO 02/20923 et WO 03/077207 divulguent un système pour verrouiller automatiquement un véhicule automobile lorsqu'on détecte la présence d'un identifiant dans la zone de surveillance du véhicule.The request for European patent EP 0690190 discloses a system for automatically locking a motor vehicle when a control signal is transmitted by a key module. International applications WO 02/20923 and WO 03/077207 disclose a system for automatically locking a motor vehicle when detecting the presence of an identifier in the vehicle surveillance area.

Un inconvénient de ce type de dispositif concerne le risque de non verrouillage du véhicule par absence de détection et/ou défaut de décodage du signal reçu. En effet, dans le cas où le signal émis par les moyens d'émission n'est pas détecté par les moyens de réception et/ou décodé par les moyens de commande, ceux-ci n'activent pas le verrouillage du véhicule.A disadvantage of this type of device relates to the risk of non-locking the vehicle by lack of detection and / or decoding of the received signal. Indeed, in the case where the signal emitted by the transmitting means is not detected by the receiving means and / or decoded by the control means, they do not activate the locking of the vehicle.

Une absence de détection et/ou défaut de décodage peut apparaître par exemple en cas :

  • de disfonctionnement des moyens d'émission et/ou de réception et/ou de commande, ou
  • d'obstacle à la réception du signal par les moyens de réception.
An absence of detection and / or lack of decoding can appear for example in case:
  • malfunction of the transmission and / or reception and / or control means, or
  • obstacle to receiving the signal by the receiving means.

On connaît également des dispositifs de verrouillage électronique basé sur la condamnation du véhicule suite à la non réception d'un signal.Also known electronic locking devices based on the conviction of the vehicle following the non-receipt of a signal.

Le principe de fonctionnement est le suivant. Les moyens d'émission émettent un signal radiofréquence codé en permanence. Lorsque les moyens d'émission sont à proximité ou dans le véhicule, le signal émis est détecté par les moyens de réception. Lorsque les moyens d'émission sont à une certaine distance du véhicule, les moyens de réception ne détectent plus le signal. En réponse à cette disparition du signal, les moyens de commande activent le verrouillage du véhicule.The operating principle is as follows. The transmitting means emit a radiofrequency signal coded continuously. When the transmission means are in the vicinity or in the vehicle, the transmitted signal is detected by the reception means. When the transmission means are at a distance from the vehicle, the receiving means no longer detect the signal. In response to this disappearance of the signal, the control means activate the locking of the vehicle.

La demande de brevet français FR 2868108 divulgue un procédé pour condamner automatiquement un véhicule automobile lorsqu'aucun signal de réponse électromagnétique émis par un dispositif identifiant n'est détecté.The request for French patent FR 2868108 discloses a method for automatically locking a motor vehicle when no electromagnetic response signal from an identifying device is detected.

Un inconvénient de ce type de dispositif de verrouillage concerne le risque de condamnation intempestive du véhicule suite à une disparition du signal. En effet, dans le cas où le signal émis n'est pas détecté par les moyens de réception et/ou décodé par les moyens de commande, ceux-ci activent le verrouillage du véhicule.A disadvantage of this type of locking device is the risk of untimely condemnation of the vehicle following a disappearance of the signal. Indeed, in the case where the transmitted signal is not detected by the receiving means and / or decoded by the control means, they activate the locking of the vehicle.

Un but de la présente invention est de fournir un dispositif électronique de verrouillage à distance pour véhicule permettant de pallier au moins l'un des inconvénients précités.An object of the present invention is to provide an electronic device remote locking for vehicle to overcome at least one of the aforementioned drawbacks.

DESCRIPTION D'UN MODE DE REALISATION DE L'INVENTIONDESCRIPTION OF AN EMBODIMENT OF THE INVENTION

Le dispositif selon un mode préféré de réalisation de l'invention va maintenant être détaillé en référence aux figures. Les éléments équivalents représentés dans les différentes figures porteront les mêmes références numériques.The device according to a preferred embodiment of the invention will now be detailed with reference to the figures. The equivalent elements represented in the different figures will bear the same numerical references.

En référence à la figure 1, on a illustré un véhicule 40 comprenant un dispositif électronique de verrouillage à distance selon l'invention.With reference to the figure 1 , there is illustrated a vehicle 40 comprising an electronic remote locking device according to the invention.

Le dispositif de verrouillage comprend des moyens d'émission 10, des moyens de réception 20 et des moyens de commande 30.The locking device comprises transmitting means 10, receiving means 20 and control means 30.

Les moyens de commande 30 sont aptes à basculer d'un premier mode de fonctionnement 31 à un deuxième mode de fonctionnement 32.The control means 30 are able to switch from a first mode of operation 31 to a second mode of operation 32.

Dans le premier mode de fonctionnement 31, les moyens de commande 30 verrouillent le véhicule si des premières conditions sont satisfaites.In the first mode of operation 31, the control means 30 lock the vehicle if first conditions are satisfied.

Dans le deuxième mode de fonctionnement 32, les moyens de commande 30 verrouillent le véhicule si des deuxièmes conditions sont satisfaites.In the second mode of operation 32, the control means 30 lock the vehicle if second conditions are satisfied.

Le fait que les moyens de commande 30 sont aptes à commander le verrouillage du véhicule 40 selon deux modes de fonctionnement différents 31, 32 permet au dispositif d'être plus fiable puisque plus de critères peuvent entraîner le verrouillage du véhicule 40.The fact that the control means 30 are able to control the locking of the vehicle 40 in two different modes of operation 31, 32 allows the device to be more reliable since more criteria can cause the locking of the vehicle 40.

Dans un exemple de premier mode de fonctionnement, les moyens de commande commandent le verrouillage du véhicule en réponse à la détection d'un premier signal.In an exemplary first mode of operation, the control means controls the locking of the vehicle in response to the detection of a first signal.

Dans un exemple de deuxième mode de fonctionnement, les moyens de commande commandent le verrouillage du véhicule en réponse à la non détection (i.e. disparition) d'un deuxième signal.In an exemplary second mode of operation, the control means controls the locking of the vehicle in response to the non-detection (i.e. disappearance) of a second signal.

Un des avantages de moyens de commande aptes à basculer entre les deux exemples de mode de fonctionnement décrits ci-dessus est de diminuer le risque de non verrouillage du véhicule, par exemple du fait de la non détection du premier signal.One of the advantages of control means able to switch between the two examples of operating mode described above is to reduce the risk of non-locking of the vehicle, for example due to the non-detection of the first signal.

Dans la suite, on décrira l'invention en supposant que les premier et deuxième modes de fonctionnement sont ceux des exemples donnés ci-dessus, étant entendu que d'autres modes de fonctionnement peuvent être adoptés.In the following, the invention will be described assuming that the first and second modes of operation are those of the examples given above, it being understood that other modes of operation may be adopted.

Les moyens d'émission 10 sont aptes à émettre le premier signal 11 et le deuxième signal 12.The transmission means 10 are able to transmit the first signal 11 and the second signal 12.

Les moyens d'émission 10 comprennent des moyens d'actionnement (non représentés), tel qu'un ou plusieurs boutons.The transmission means 10 comprise actuating means (not shown), such as one or more buttons.

L'actionnement des moyens d'actionnement commande l'émission par les moyens d'émission 10 du premier signal 11.The actuation of the actuating means controls the transmission by the transmission means 10 of the first signal 11.

Le premier signal 11 est utilisé dans le premier mode de fonctionnement 31 : les moyens de commande 30 commandent le verrouillage du véhicule 40 en réponse à la détection du premier signal 11.The first signal 11 is used in the first operating mode 31: the control means 30 control the locking of the vehicle 40 in response to the detection of the first signal 11.

On entend, dans le cadre de la présente invention, par « verrouillage du véhicule », la condamnation des portes et/ou du coffre et/ou du capot et/ou de la trappe d'alimentation en carburant du véhicule. Par ailleurs, il est à noter que le terme « verrouillage du véhicule » comprend également les opérations annexes à la condamnation du véhicule, comme par exemple la fermeture du système d'éclairage et/ou de ventilation du véhicule, le rabattement automatique des rétroviseurs etc.In the context of the present invention, the term "locking of the vehicle" means the locking of the doors and / or the boot and / or the bonnet and / or the fuel supply hatch of the vehicle. Furthermore, it should be noted that the term "locking of the vehicle" also includes operations ancillary to the conviction of the vehicle, such as for example the closing of the lighting system and / or ventilation of the vehicle, the automatic folding of mirrors etc. .

Le premier signal 11 est émis de manière ponctuelle, lors de l'actionnement des moyens d'actionnement par l'utilisateur.The first signal 11 is emitted in a specific manner, when the actuating means are actuated by the user.

Dans un mode de réalisation, l'actionnement des moyens d'actionnement entraîne l'émission redondante du premier signal 11. En effet, le premier signal 11 peut être envoyé « en rafale », par exemple périodiquement pendant une durée égale à trois périodes.In one embodiment, the actuation of the actuating means causes the redundant transmission of the first signal 11. Indeed, the first signal 11 can be sent "burst", for example periodically for a period equal to three periods.

La redondance du premier signal 11 permet d'améliorer la fiabilité du verrouillage du véhicule 40. Par ailleurs, cette solution technique n'augmente pas le temps de traitement d'une commande de verrouillage.The redundancy of the first signal 11 improves the reliability of the locking of the vehicle 40. Moreover, this technical solution does not increase the processing time of a lock control.

La figure 2 illustre un mode d'émission dans lequel l'actionnement 14 des moyens d'actionnement entraîne l'émission du premier signal 15 à trois reprises.The figure 2 illustrates a transmission mode in which the actuation 14 of the actuating means causes the emission of the first signal 15 three times.

Dans ce mode, on utilise un premier signal 11 commandant aux moyens de commande 30 de verrouiller le véhicule 40, avec répétition de l'émission de ce premier signal 11 : les moyens de commande 30 peuvent verrouiller le véhicule 40 à la détection et au décodage du premier signal 11, mais ce premier signal 11 est émis plusieurs fois par les moyens d'émission 10.In this mode, a first signal 11 is used which commands the control means 30 to lock the vehicle 40, with repetition of the transmission of this first signal 11: the control means 30 can lock the vehicle 40 to detection and decoding of the first signal 11, but this first signal 11 is emitted several times by the transmission means 10.

La périodicité des émissions 15 répétées du premier signal 11 peut varier au cours du temps : par exemple, on peut décider d'une fréquence d'émission du premier signal 11 très fortes (pour se prémunir de trous locaux dans la réception du signal) durant un délai d'une à deux secondes puis diminuer la fréquence d'émission du premier signal (pour se prémunir d'un obstacle perturbateur par exemple).The periodicity of the repeated transmissions of the first signal 11 may vary over time: for example, it is possible to decide on a frequency for transmitting the first signal 11 very strong (to guard against local holes in the reception of the signal) for a delay of one to two seconds and then to reduce the transmission frequency of the first signal (to guard against a disruptive obstacle for example).

Comme indiqué précédemment, les moyens d'émission 10 sont également aptes à émettre le deuxième signal 12.As indicated above, the transmission means 10 are also able to transmit the second signal 12.

Le deuxième signal 12 est utilisé dans le deuxième mode de fonctionnement 32 : les moyens de commande 30 commandent le verrouillage du véhicule 40 en réponse à la non détection du deuxième signal 12.The second signal 12 is used in the second operating mode 32: the control means 30 control the locking of the vehicle 40 in response to the non-detection of the second signal 12.

Le deuxième signal 12 est émis de manière permanente. Cette émission permanente peut être une émission continue ou périodique : en d'autre terme, l'expression « émission permanente » signifie l'émission automatique d'un signal indépendamment d'une quelconque activation par l'utilisateur.The second signal 12 is permanently transmitted. This permanent transmission can be a continuous or periodic transmission: in other words, the term "permanent transmission" means the automatic transmission of a signal independently of any activation by the user.

Les moyens de réception 20 permettent la réception des premier et deuxième signaux 11, 12. Les moyens de réception 20 sont par exemple des antennes externes ou internes disposées à l'extérieur et/ou à l'intérieur du véhicule 40.The reception means 20 allow the reception of the first and second signals 11, 12. The receiving means 20 are, for example, external or internal antennas arranged outside and / or inside the vehicle 40.

Les moyens de réception 20 sont reliés aux moyens de commande 30. Ils sont aptes à transmettre les premier et deuxième signaux 11, 12 aux moyens de commande 30 qui traitent ces signaux.The reception means 20 are connected to the control means 30. They are able to transmit the first and second signals 11, 12 to the control means 30 which process these signals.

Les moyens de commande 30 permettent notamment la commande du verrouillage du véhicule.The control means 30 allow in particular the control of the vehicle lock.

Comme indiqué précédemment, les moyens de commande 30 sont aptes à fonctionner dans deux modes de fonctionnement différents.As indicated above, the control means 30 are able to operate in two different modes of operation.

Les moyens de commande 30 comprennent des moyens de basculement 31 pour basculer d'un mode de fonctionnement à l'autre. En d'autres termes, les moyens de basculement sont aptes à faire basculer les moyens de commande :

  • du premier mode de fonctionnement 31 au deuxième mode de fonctionnement 32,
  • du deuxième mode de fonctionnement 32 au premier mode de fonctionnement 31.
The control means 30 comprise tilting means 31 for switching from one operating mode to another. In other words, the tilting means are able to switch the control means:
  • from the first mode of operation 31 to the second mode of operation 32,
  • from the second operating mode 32 to the first operating mode 31.

Dans le premier mode de fonctionnement 31, les moyens de commande 30 verrouillent le véhicule 40 en réponse à la détection du premier signal 11 émis par les moyens d'émission 10.In the first mode of operation 31, the control means 30 lock the vehicle 40 in response to the detection of the first signal 11 emitted by the transmission means 10.

Dans le deuxième mode de fonctionnement 32, les moyens de commande 30 verrouillent le véhicule 40 en réponse à une disparition d'un deuxième signal 12 émis par les moyens d'émission 10.In the second mode of operation 32, the control means 30 lock the vehicle 40 in response to a disappearance of a second signal 12 emitted by the transmission means 10.

Les moyens de commande 30 du dispositif selon l'invention sont programmés pour mettre en oeuvre le procédé décrit ci-dessous en référence à la figure 3.The control means 30 of the device according to the invention are programmed to implement the method described below with reference to the figure 3 .

Le procédé comprend une étape 100 de détection du premier signal 11. Au cours de cette étape, les moyens de commande 30 traitent les informations reçues des moyens de réception 20 pour détecter le premier signal 11 émis par les moyens d'émission en cas d'actionnement des moyens d'actionnement par l'utilisateur.The method comprises a step 100 of detecting the first signal 11. During this step, the control means 30 process the information received from the reception means 20 to detect the first signal 11 emitted by the transmission means in the event of actuation of the actuating means by the user.

Si le premier signal 11 est détecté, l'étape suivante 200 du procédé consiste à commander le verrouillage du véhicule. Le procédé de verrouillage du véhicule 40 est terminé (étape 300) : les moyens de commande 30 reprendront le procédé à l'étape 100 une fois le véhicule 40 déverrouillé.If the first signal 11 is detected, the next step 200 of the method is to control the locking of the vehicle. The locking method of the vehicle 40 is completed (step 300): the control means 30 will resume the method in step 100 once the vehicle 40 has unlocked.

Si le premier signal n'est pas détecté, l'étape 400 suivante consiste à vérifier la présence du deuxième signal 12.If the first signal is not detected, the next step 400 consists in checking the presence of the second signal 12.

Si le deuxième signal 12 est détecté, le procédé revient à l'étape 100 consistant à tenter de détecter le premier signal 11.If the second signal 12 is detected, the method returns to step 100 of attempting to detect the first signal 11.

Si le deuxième signal 12 n'est pas détecté, l'étape suivante 500 consiste à commander le verrouillage du véhicule 40. Le procédé de verrouillage du véhicule est terminé (étape 600) : les moyens de commande 30 reprendront le procédé à l'étape 100 une fois le véhicule 40 déverrouillé.If the second signal 12 is not detected, the next step 500 consists in controlling the locking of the vehicle 40. The locking method of the The vehicle is completed (step 600): the control means 30 will resume the method in step 100 once the vehicle 40 has unlocked.

Le procédé a été décrit de façon simplifié pour en faire ressortir les principales étapes.The process has been described in a simplified way to bring out the main steps.

Toutefois, d'autres critères de verrouillage peuvent entrer en ligne de compte : notamment, la présence d'une porte de véhicule ouverte, ou encore le fait que le moteur du véhicule soit allumé.However, other locking criteria can be taken into account: in particular, the presence of an open vehicle door, or the fact that the vehicle engine is on.

Par ailleurs, le procédé de verrouillage peut être rendu passif (c'est à dire qu'on ne cherche pas à détecter les premier et deuxième signaux) pendant une certaine durée souhaitée, ou si d'autres conditions de verrouillage (moteur allumé) ne sont pas satisfaites.Moreover, the locking method can be rendered passive (ie it does not seek to detect the first and second signals) for a certain desired duration, or if other locking conditions (engine on) do not are not satisfied.

Par exemple lorsque d'autres conditions empêchent le verrouillage du véhicule : par exemple lorsqu'une porte du véhicule est ouverte, lorsque le moteur du véhicule est allumé, etc.For example when other conditions prevent the locking of the vehicle: for example when a door of the vehicle is open, when the engine of the vehicle is on, etc.

De plus, le procédé peut comprendre une étape supplémentaire lorsque le deuxième signal n'est plus détecté : cette étape supplémentaire consiste à tenter de détecter le deuxième signal en utilisant tous les éléments (antennes intérieures et extérieures) des moyens de réception 20 à pleine puissance pour couvrir une zone maximum et s'assurer de la disparition du deuxième signal 12.In addition, the method may comprise an additional step when the second signal is no longer detected: this additional step consists in attempting to detect the second signal using all the elements (inside and outside antennas) of the reception means 20 at full power to cover a maximum area and ensure the disappearance of the second signal 12.

Le principe de fonctionnement du dispositif décrit ci-dessus est le suivant.The operating principle of the device described above is as follows.

On suppose que les moyens de commande 30 sont initialement dans le premier mode de fonctionnement 31. Ce premier mode 31 correspond au cas où les moyens de commande 30 commandent le verrouillage du véhicule 40 en réponse à la détection du premier signal 11.It is assumed that the control means 30 are initially in the first mode of operation 31. This first mode 31 corresponds to the case where the control means 30 control the locking of the vehicle 40 in response to the detection of the first signal 11.

Les moyens de commande 30 tentent de détecter les premier et deuxième signaux 11, 12 parmi les informations reçues des moyens de réception 20.The control means 30 attempts to detect the first and second signals 11, 12 among the information received from the reception means 20.

L'utilisateur actionne les moyens d'actionnement. Les moyens d'émission 10 émettent le premier signal 11 pour commander le verrouillage à distance du véhicule.The user actuates the actuating means. The transmission means 10 emit the first signal 11 to control the remote locking of the vehicle.

Si les moyens de commande 30 détectent correctement le premier signal 11 parmi les informations reçues des moyens de réception 20, alors les moyens de commande 30 activent le verrouillage du véhicule 40.If the control means 30 correctly detect the first signal 11 among the information received from the reception means 20, then the control means 30 activate the locking of the vehicle 40.

Si le premier signal 11 n'est pas détecté, les moyens de commande n'activent pas le verrouillage du véhicule.If the first signal 11 is not detected, the control means do not activate the locking of the vehicle.

L'utilisateur s'éloigne du véhicule 40. Lorsque la distance entre l'utilisateur et le véhicule est suffisante, les moyens de réception 20 ne reçoivent plus le deuxième signal 12 émis par les moyens d'émission 10.The user moves away from the vehicle 40. When the distance between the user and the vehicle is sufficient, the receiving means 20 no longer receive the second signal 12 emitted by the transmission means 10.

Les moyens de commande 30 ne détectent plus le deuxième signal 12, les moyens de commande activent alors le verrouillage du véhicule.The control means 30 no longer detect the second signal 12, the control means then activate the locking of the vehicle.

Le dispositif selon l'invention qui utilise au moins deux modes de fonctionnement pour le verrouillage du véhicule par les moyens de commande 30 permet de limiter les risques que le véhicule soit déverrouillé malgré une commande de verrouillage par l'utilisateur.The device according to the invention which uses at least two modes of operation for the locking of the vehicle by the control means 30 makes it possible to limit the risks that the vehicle is unlocked despite a lock command by the user.

Le lecteur aura compris que de nombreuses modifications peuvent être apportées sans sortir matériellement des nouveaux enseignements et des avantages décrits ici. Par conséquent, toutes les modifications de ce type sont destinées à être incorporées à l'intérieur de la portée de la carrosserie de véhicule telle que définie dans les revendications jointes.The reader will understand that many changes can be made without materially escaping the new lessons and benefits described here. Therefore, all modifications of this type are intended to be incorporated within the scope of the vehicle body as defined in the appended claims.
