Description

Description AGENCEMENT DE SERRURE POUR VÉHICULE AUTOMOBILE À OUVERTURE ÉLECTRIQUE Description LOCK ARRANGEMENT FOR A MOTOR VEHICLE WITH ELECTRIC OPENING
[001] L'invention concerne un agencement de serrure pour véhicule automobile, à ouverture électrique, connectée à des moyens principaux d'alimentation électrique et à des moyens de secours d'alimentation électrique de la serrure en cas de dysfonctionnement des moyens principaux, ces moyens de secours comprenant un composant de réserve de puissance.The invention relates to a lock arrangement for a motor vehicle, with electric opening, connected to main means of electrical supply and to backup means of electrical supply of the lock in the event of malfunction of the main means, these emergency means comprising a power reserve component.
[002] Le document de brevet EP 1 130202 propose d'utiliser un composant électronique de réserve de puissance constitué d'un supercondensateur- Un tel supercondensateur constitue une source d'énergie rechargeable et compacte. Lors de l'utilisation normale du véhicule, ce composant électronique n'est pas sollicité tant que les moyens principaux d'alimentation électrique fonctionnent normalement. Ces moyens principaux maintiennent alors en permanence le supercondensateur en charge. Lorsque, à la suite d'une défaillance des moyens d'alimentation principaux, ces derniers ne sont plus en mesure de fournir l'énergie électrique pour l'ouverture de la serrure, une carte électronique bascule automatiquement sur le supercondensateur qui peut permettre le fonctionnement de la serrure pendant plusieurs cycles d'ouverture.Patent document EP 1 130202 proposes using an electronic power reserve component consisting of a supercapacitor. Such a supercapacitor constitutes a rechargeable and compact source of energy. During normal use of the vehicle, this electronic component is not used as long as the main means of electrical supply operate normally. These main means then permanently maintain the supercapacitor in charge. When, following a failure of the main supply means, the latter are no longer able to provide electrical energy for the opening of the lock, an electronic card automatically switches to the supercapacitor which can allow operation of the lock for several opening cycles.
[003] Un tel agencement de secours est fiable en cas d'ouverture relativement rapide de la serrure, après la défaillance des moyens d'alimentation principaux, comme c'est le cas par exemple lors d'un accident.Such an emergency arrangement is reliable in the case of relatively rapid opening of the lock, after the failure of the main supply means, as is the case for example during an accident.
[004] Par contre, si un laps de temps relativement grand s'écoule entre l'arrêt par dysfonctionnement des moyens d'alimentation principaux et l'ouverture de la serrure, le supercondensateur à l'état passif se déchargeant relativement rapidement, il peut arriver que ce supercondensateur se soit déchargé et la serrure ne comporte alors aucun moyen de secours fonctionnel. C'est le cas par exemple lors d'un stationnement ou plus généralement d'une non-utilisation du véhicule pendant plusieurs jours.On the other hand, if a relatively large period of time elapses between the malfunctioning shutdown of the main supply means and the opening of the lock, the supercapacitor in the passive state discharging relatively quickly, it can happen that this supercapacitor has discharged and the lock does not include any functional backup means. This is the case, for example, when parking or more generally when the vehicle is not used for several days.
[005] Pour résoudre ce problème, il peut être envisagé que les moyens de secours comprennent également des moyens de réserve d'énergie électrique connectables au composant de réserve de puissance.To solve this problem, it can be envisaged that the emergency means also include electrical energy reserve means connectable to the power reserve component.
[006] C'est le cas de la serrure décrite dans les documents de brevet US 5497 641 et US 6 056076.This is the case of the lock described in the patent documents US 5497 641 and US 6 056076.
[007] Selon ces documents, en cas de défaillance des moyens principaux d'alimentation électrique, des moyens de réserve de puissance sont commutés et peuvent être chargés par des moyens de réserve d'énergie électrique couplés avec la poignée du véhicule. Les moyens de réserve d'énergie rechargent alors les moyens de réserve de puissance, qui une fois un seuil de charge suffisant atteint, alimentent un récepteur de signal qui peut permettre le processus d'identification au moyen d'une télécommande. C'est par P intermédiaire de ce récepteur que la serrure est alimentée.According to these documents, in the event of failure of the main electrical supply means, power reserve means are switched and can be charged by electrical energy reserve means coupled with the handle of the vehicle. The energy reserve means then recharge the power reserve means, which once a sufficient charge threshold is reached, feed a signal receiver which can allow the identification process by means of a remote control. It is through this receiver that the lock is supplied.
[008] Lors de l'action nécessaire pour l'ouverture de la porte, à savoir un actionnement de la poignée, les moyens de réserve d'énergie sont donc mis en fonction et l' actionnement d'ouverture effectuée, par une seule action volontaire.During the action necessary for the opening of the door, namely an actuation of the handle, the energy reserve means are therefore put into operation and the opening actuation carried out, by a single action voluntary.
[009] Cependant, un tel mode d'alimentation de secours pose le problème technique suivant.However, such a backup power mode poses the following technical problem.
[010] Lors de l' actionnement de la poignée, en cas de défaillance des moyens principaux d'alimentation, les moyens de réserve d'énergie sont mis en fonction, recharge les moyens de réserve de puissance et ce n'est qu'une fois le récepteur de signal alimenté par cette réserve de puissance que l'identification peut être effectuée.When the handle is actuated, in the event of failure of the main supply means, the energy reserve means are put into operation, recharges the power reserve means and this is only one once the signal receiver is powered by this power reserve that identification can be performed.
[011] Il en résulte une possible décharge des moyens de réserve d'énergie par toute personne non autorisée actionnant la poignée. Ceci est particulièrement préjudiciable à l'emploi de moyens de réserve d'énergie relativement simple tels que des piles dont la durée de vie doit être compatible à celle du véhicule, à savoir environ dix ans.This results in a possible discharge of the energy reserve means by any unauthorized person actuating the handle. This is particularly detrimental to the use of relatively simple energy reserve means such as batteries, the life of which must be compatible with that of the vehicle, namely approximately ten years.
[012] Pour résoudre ce problème, l'invention propose un agencement de serrure pour véhicule automobile, à ouverture électrique, connectée à des moyens principaux d'alimentation électrique et à des moyens de secours d'alimentation électrique de la serrure en cas de dysfonctionnement des moyens principaux, ces moyens de secours comprenant un composant de réserve de puissance et des moyens de réserve d'énergie électrique connectables audit composant de réserve de puissance, un organe d'identification assurant l'identification de l'utilisateur, l'organe d'identification comprenant au moins un récepteur de signal communiquant avec un élément apte à émettre un signal, pour l'identification de l'utilisateur, caractérisé en ce que la connexion desdits moyens de réserve d'énergie est commandée de sorte que ces moyens de réserve d'énergie alimentent ledit composant de réserve de puissance, une fois l'identification effectuée et autorisée.To solve this problem, the invention provides a lock arrangement for a motor vehicle, with electric opening, connected to main means of electrical supply and to backup means of electrical supply of the lock in the event of a malfunction. main means, these emergency means comprising a power reserve component and electrical energy reserve means connectable to said power reserve component, an identification member ensuring the identification of the user, the member of identification comprising at least one signal receiver communicating with an element capable of transmitting a signal, for the identification of the user, characterized in that the connection of said energy reserve means is controlled so that these reserve means of energy supply said power reserve component, once the identification has been carried out and authorized.
[013] Un tel agencement est particulièrement économique en énergie électrique.[013] Such an arrangement is particularly economical in electrical energy.
[014] Selon un mode de réalisation préféré, ledit composant de réserve de puissance est constitué d'au moins un supercondensateur.According to a preferred embodiment, said power reserve component consists of at least one supercapacitor.
[015] De préférence, lesdits moyens de réserve d'énergie sont directement connectables audit organe d'identification.Preferably, said energy reserve means are directly connectable to said identification member.
[016] Dans ce cas, de préférence, lesdits moyens de réserve d'énergie sont mis en fonction par un bouton de commande extérieur disposé sur le véhicule.In this case, preferably, said energy reserve means are activated by an external control button disposed on the vehicle.
[017] Selon une variante de réalisation, l'organe d'identification comprend en outre un barillet actionné par une clé et lesdits moyens de réserve d'énergie sont mis en fonction par actionnement d'un contact contenu dans le barillet. [018] De préférence, lesdits moyens de réserve d'énergie sont constitués d'au moins une pile électrique ou un accumulateur électrique.[017] According to an alternative embodiment, the identification member further comprises a barrel actuated by a key and said energy reserve means are activated by actuation of a contact contained in the barrel. Preferably, said energy reserve means consist of at least one electric battery or an electric accumulator.
[019] Avantageusement, ledit composant de réserve de puissance est directement connecté électriquement à la serrure.Advantageously, said power reserve component is directly electrically connected to the lock.
[020] L'invention est décrite ci-après plus en détail, à l'aide de figures ne représentant que des modes préférés de l'invention.The invention is described below in more detail, using figures representing only preferred modes of the invention.
[021] La figure 1 est un synoptique de fonctionnement d'un agencement de serrure conforme à l'invention, dont l'identification est faite grâce à une télécommande RF.[021] Figure 1 is a block diagram of a lock arrangement according to the invention, the identification of which is made by means of an RF remote control.
[022] La figure 2 est un synoptique de fonctionnement d'un agencement de serrure conforme à l'invention, dont l'identification est faite grâce aune télécommande ou un badge RF pourvu d'une clé mécanique de secours.[022] Figure 2 is a block diagram of a lock arrangement according to the invention, the identification of which is made using a remote control or an RF badge provided with a mechanical emergency key.
[023] La figure 3 est un synoptique de fonctionnement d'un agencement de serrure conforme à l'invention, dont l'identification est faite grâce à un badge RF dit de « mains libres ».FIG. 3 is a block diagram of the operation of a lock arrangement in accordance with the invention, the identification of which is made by means of a so-called “hands-free” RF badge.
[024] Dans les différents modes de réalisation, une serrure 1 pour véhicule automobile, à assistance d'ouverture électrique, est reliée à une poignée extérieure 2A et une poignée intérieure 2B, pour la commande de son ouverture extérieure et intérieure. Elle comporte une carte électronique formant une interface destinée à raccorder la serrure à des moyens principaux d'alimentation électrique et à des moyens de commande.In the various embodiments, a lock 1 for a motor vehicle, with electric opening assistance, is connected to an exterior handle 2A and an interior handle 2B, for controlling its exterior and interior opening. It comprises an electronic card forming an interface intended to connect the lock to main electrical supply means and to control means.
[025] Elle est donc connectée à des moyens principaux d'alimentation électrique, en général une batterie 3 équipant et alimentant le véhicule automobile. Cette batterie 3 alimente un organe d'identification de signal 4, en général un récepteur RF, une électronique de gestion de condamnation 5 qui actionne la condamnation ou la décon- damnation de la serrure et un composant de réserve de puissance 6, avantageusement un supercondensateur.It is therefore connected to the main means of electrical supply, in general a battery 3 equipping and supplying the motor vehicle. This battery 3 supplies a signal identification unit 4, in general an RF receiver, a condemnation management electronics 5 which actuates the locking or unlocking of the lock and a power reserve component 6, advantageously a supercapacitor .
[026] Le composant de réserve de puissance 6, avantageusement un supercondensateur, sont directement connectés électriquement à la serrure 1. En cas de défaillance de la batterie, la carte électronique de la serrure bascule automatiquement sur le supercondensateur 6 qui peut permettre le fonctionnement de la serrure 1 pendant plusieurs cycles d'ouverture. Cette opération de secours est donc transparente pour l'utilisateur. Comme on l'a déjà vu, cela suppose que le laps de temps entre le début de la défaillance de la batterie 3 et cette commande d'ouverture ne soit pas trop long, c'est en particulier le cas lors d'un accident où les secours interviennent rapidement. Le composant 6 assure alors l'alimentation de secours nécessaire à l'ouverture de la porte de véhicule, comme d'ailleurs décrit dans le document de brevet EP 1 130202.The power reserve component 6, advantageously a supercapacitor, are directly electrically connected to the lock 1. In the event of a battery failure, the electronic card of the lock automatically switches to the supercapacitor 6 which can allow the operation of lock 1 for several opening cycles. This backup operation is therefore transparent to the user. As we have already seen, this assumes that the time between the start of the failure of the battery 3 and this opening command is not too long, this is particularly the case during an accident where emergency services intervene quickly. Component 6 then provides the emergency power supply necessary for opening the vehicle door, as moreover described in patent document EP 1 130202.
[027] Selon le premier mode de réalisation illustré sur la figure 1, l'identification se fait à l'aide d'une télécommande RF 7 A.[027] According to the first embodiment illustrated in Figure 1, the identification is done using an RF remote control 7 A.
[028] En mode normal de fonctionnement, lorsque la batterie 3 fonctionne normalement, l'utilisateur actionne cette télécommande 7A qui communique avec le récepteur RF 4, disposé à l'intérieur du véhicule. Une fois la reconnaissance de l'identifiant effectué, ce récepteur 4 commute l'électronique de gestion 5 entraînant la décondamnation de la serrure 1. Par action sur la poignée 2A, la batterie alimente la serrure 1 qui peut être ouverte.[028] In normal operating mode, when the battery 3 is operating normally, the user operates this remote control 7A which communicates with the RF receiver 4, located inside the vehicle. Once the identifier has been recognized, this receiver 4 switches the management electronics 5 leading to unlocking of the lock 1. By action on the handle 2A, the battery supplies the lock 1 which can be opened.
[029] En cas de défaillance de la batterie, la carte électronique de la serrure bascule automatiquement sur le supercondensateur 6 qui peut permettre l'ouverture de la serrure 1, en cas d'accident par exemple.[029] In the event of a battery failure, the electronic card of the lock automatically switches to the supercapacitor 6 which can allow the lock 1 to open, in the event of an accident for example.
[030] Si ce supercondensateur 6 est déchargé par exemple après un stationnement de longue durée du véhicule, l' actionnement de la télécommande 7A par l'utilisateur ne donne aucun résultat.If this supercapacitor 6 is discharged, for example after long-term parking of the vehicle, the actuation of the remote control 7A by the user gives no result.
[031] Par une action volontaire, de préférence par actionnement d'un bouton 10 porté par l'extérieur du véhicule, l'utilisateur met en fonction les moyens de réserve d'énergie 9 qui, grâce à une commutation 8A, alimente en premier lieu le récepteur 4.[031] By voluntary action, preferably by actuation of a button 10 carried by the exterior of the vehicle, the user activates the energy reserve means 9 which, thanks to a switching 8A, supplies power first place the receiver 4.
[032] L'identification peut donc s'opérer par liaison RF entre la télécommande 7A et le récepteur 4. Ce n'est qu'une fois l'utilisateur reconnu, que la commutation est effectuée pour que les moyens de réserve d'énergie alimentent l'électronique de gestion 5 et le supercondensateur 6 qui se recharge rapidement en quelques secondes.The identification can therefore take place by RF link between the remote control 7A and the receiver 4. It is only after the user has been recognized that the switching is carried out so that the energy reserve means supply the management electronics 5 and the supercapacitor 6 which recharges quickly in a few seconds.
[033] Juste après cette première action volontaire sur le bouton 10, l'utilisateur est donc identifié par action classique sur la télécommande puis la décondamnation de la serrure 1 est autorisée. La serrure 1 peut ensuite être ouverte grâce au supercondensateur 6 rechargé, par action sur la poignée 2A.Just after this first voluntary action on the button 10, the user is therefore identified by conventional action on the remote control then unlocking of the lock 1 is authorized. The lock 1 can then be opened by means of the recharged supercapacitor 6, by action on the handle 2A.
[034] Selon le deuxième mode de réalisation illustré sur la figure 2, l'identification se fait à l'aide d'un badge RF pourvu d'une clé mécanique de secours 7B.[034] According to the second embodiment illustrated in Figure 2, the identification is done using an RF badge provided with a mechanical emergency key 7B.
[035] En mode normal de fonctionnement, lorsque la batterie 3 fonctionne normalement, l'utilisateur approche à une distance seuil du véhicule et son badge RF communique avec le récepteur RF 4, disposé à l'intérieur du véhicule. Une fois la reconnaissance de l'identifiant effectué, ce récepteur 4 commute l'électronique de gestion 5 entraînant la décondamnation de la serrure 1. Par action sur la poignée 2A, la batterie alimente la serrure 1 qui peut être ouverte.In normal operating mode, when the battery 3 is operating normally, the user approaches a threshold distance from the vehicle and his RF badge communicates with the RF receiver 4, disposed inside the vehicle. Once the identifier has been recognized, this receiver 4 switches the management electronics 5 causing the unlocking of the lock 1. By action on the handle 2A, the battery supplies the lock 1 which can be opened.
[036] En cas de défaillance de la batterie, la carte électronique électronique bascule automatiquement sur le supercondensateur 6 qui peut permettre l'ouverture de la serrure 1, par exemple en cas d'accident.In the event of a battery failure, the electronic electronic card automatically switches to the supercapacitor 6 which can allow the lock 1 to open, for example in the event of an accident.
[037] Si ce supercondensateur 6 est déchargé par exemple après un stationnement de longue durée du véhicule, la présence du badge 7B porté par l'utilisateur ne donne aucun résultat.[037] If this supercapacitor 6 is discharged for example after long-term parking of the vehicle, the presence of the badge 7B worn by the user gives no result.
[038] L'utilisateur utilise alors la clé mécanique portée par son badge 7B, ou d'ailleurs indépendante de ce dernier, et l'introduit dans un barillet porté par la porte. Ce barillet 8B comporte un contact effectuant la commutation mettant en fonction les moyens de réserve d'énergie 9 qui alimente successivement ou simultanément le récepteur 4, l'électronique de gestion 5 et le supercondensateur 6 qui se recharge rapidement.[038] The user then uses the mechanical key carried by his badge 7B, or moreover independent of the latter, and introduces it into a barrel carried by the door. This barrel 8B comprises a contact carrying out the switching putting into operation the energy reserve means 9 which successively or simultaneously supplies the receiver 4, the management electronics 5 and the supercapacitor 6 which recharges quickly.
[039] Juste après cette action volontaire consistant à actionner la clé mécanique dans son barillet, l'utilisateur est identifié par liaison RF entre son badge et le récepteur 4 et la décondamnation de la serrure 1 est autorisée. La serrure 1 peut ensuite être ouverte grâce au supercondensateur 6 rechargé, par action sur la poignée 2A.[039] Just after this voluntary action consisting in actuating the mechanical key in its barrel, the user is identified by RF link between his badge and the receiver 4 and unlocking of the lock 1 is authorized. The lock 1 can then be opened by means of the recharged supercapacitor 6, by action on the handle 2A.
[040] Selon le troisième mode de réalisation illustré sur la figure 3, l'identification se fait à l'aide d'un badge RF 7C pourvu ou non d'une clé mécanique de secours.[040] According to the third embodiment illustrated in Figure 3, the identification is done using an RF badge 7C provided or not with a mechanical emergency key.
[041] En mode normal de fonctionnement, lorsque la batterie 3 fonctionne normalement, l'utilisateur approche à une distance seuil du véhicule et son badge RF communique avec le récepteur RF 4, disposé à l'intérieur du véhicule. Une fois la reconnaissance de l'identifiant effectué, ce récepteur 4 commute l'électronique de gestion 5 entraînant la décondamnation de la serrure 1. Par action sur la poignée 2A, la batterie alimente la serrure 1 qui peut être ouverte.[041] In normal operating mode, when the battery 3 is operating normally, the user approaches a threshold distance from the vehicle and his RF badge communicates with the RF receiver 4, placed inside the vehicle. Once the identifier has been recognized, this receiver 4 switches the management electronics 5 causing the unlocking of the lock 1. By action on the handle 2A, the battery supplies the lock 1 which can be opened.
[042] En cas de défaillance de la batterie, la carte électronique de la serrure bascule automatiquement sur le supercondensateur 6 qui peut permettre l'ouverture de la serrure 1, par exemple en cas d'accident.[042] In the event of a battery failure, the electronic card of the lock automatically switches to the supercapacitor 6 which can allow the lock 1 to open, for example in the event of an accident.
[043] Si ce supercondensateur 6 est déchargé par exemple après un stationnement de longue durée du véhicule, la présence du badge 7B porté par l'utilisateur ne donne aucun résultat.[043] If this supercapacitor 6 is discharged for example after long-term parking of the vehicle, the presence of the badge 7B worn by the user gives no result.
[044] Par une action volontaire, de préférence par actionnement d'un bouton 10 porté par l'extérieur du véhicule, l'utilisateur met en fonction les moyens de réserve d'énergie 9 qui, grâce à une commutation 8C, alimente en premier lieu le récepteur 4.[044] By voluntary action, preferably by actuation of a button 10 carried by the exterior of the vehicle, the user activates the energy reserve means 9 which, thanks to a switching 8C, supplies power first place the receiver 4.
[045] L'identification peut donc s'opérer par liaison RF entre le badge 7C et le récepteur 4. Ce n'est qu'une fois l'utilisateur reconnu, que la commutation est effectuée pour que les moyens de réserve d'énergie alimentent l'électronique de gestion 5 et le supercondensateur 6 qui se recharge rapidement.The identification can therefore take place by RF link between the badge 7C and the receiver 4. It is only after the user has been recognized that the switching is carried out so that the energy reserve means supply the management electronics 5 and the supercapacitor 6 which recharges quickly.
[046] Juste après cette action volontaire consistant à actionner le bouton 10 externe au véhicule, l'utilisateur est donc identifié puis la décondamnation de la serrure 1 est autorisée. La serrure 1 peut ensuite être ouverte grâce au supercondensateur 6 rechargé, par action sur la poignée 2A.[046] Just after this voluntary action consisting in actuating the button 10 external to the vehicle, the user is therefore identified and then unlocking of the lock 1 is authorized. The lock 1 can then be opened by means of the recharged supercapacitor 6, by action on the handle 2A.
[047] Selon l'invention, les moyens de réserve d'énergie électrique 9 peuvent être un ensemble de piles ou d'accumulateurs ou une pile ou un accumulateur couplé à un convertisseur élévateur de tension. Ces moyens de réserve d'énergie électrique peuvent être internes au véhicule ou être portables et connectables de l'extérieur du véhicule.[047] According to the invention, the electrical energy reserve means 9 can be a set of batteries or accumulators or a battery or an accumulator coupled to a step-up converter. These electrical energy reserve means can be internal to the vehicle or be portable and connectable from outside the vehicle.
[048] Comme il a été vu, l'invention s'applique à une serrure associée à une identification par télécommande RF ou badge RF, avec éventuellement clé mécanique de secours ou associée à une identification mécanique par clé et barillet. Elle s'applique également à une serrure insérée dans un module de porte, où serrure, organe d'identification et électronique de gestion de condamnation sont intégrés dans une porte de véhicule automobile. L'invention s'applique également à tout identifiant de type badge ou télécommande.[048] As has been seen, the invention applies to a lock associated with identification by RF remote control or RF badge, possibly with an emergency mechanical key or associated with mechanical identification by key and barrel. It also applies to a lock inserted in a door module, where the lock, identification member and electronic management of conviction are integrated in a door of a motor vehicle. The invention also applies to any badge or remote control type identifier.
Par exemple, au lieu d'un récepteur et d'un badge RF, il peut être utilisé un système à transpondeur activé par un identifiant déclenchant un détecteur de proximité sans contact de type capteur Hall. For example, instead of a receiver and an RF badge, a transponder system can be used activated by an identifier triggering a contactless proximity detector of the Hall sensor type.
