Description

L'invention concerne un procédé et un dispositif de com m ande d'un ouvrant de véhicule. The invention relates to a method and a device for com meate a vehicle opening.
L'invention concerne plus précisément un procédé et un dispositif de com m ande de verrouillage d'un ouvrant de véhicule. L'invention trouve son application en particulier pour un ouvrant de coffre m uni d'un hayon, équipant en particulier les véhicules autom obiles de type m onospace ou tout terrain.The invention more specifically relates to a method and a device for locking a vehicle door. The invention finds its application in particular for a tailgate opening of a tailgate, particularly equipping autom obile vehicles m onospace type or all terrain.
L'ouverture, la ferm eture, le verrouillage et le déverrouillage d'un ouvrant de véhicule sont souvent contrôlées par un calculateur, qui est par exem ple l'unité centrale habitacle (aussi appelé calculateur central) .The opening, closing, locking and unlocking of a vehicle opening are often controlled by a computer, which is for example the cabin central unit (also called central computer).
Par exem ple, chaque serrure de porte et du hayon du véhicule comprend un contacteur électrique qui signale le début ou la fin d'une opération de ferm eture de l'ouvrant concerné au calculateur central.For example, each door lock and the tailgate of the vehicle comprises an electric switch that signals the start or the end of a closing operation of the opening concerned to the central computer.
L'information ainsi envoyée par chacun des contacteurs électriques perm et alors à l'unité centrale habitacle d'intégrer le fait que tous les ouvrants sont à l'état fermé. A réception de ces informations, l'unité centrale habitacle peut alors enchaîner une autre action, par exemple le verrouillage des ouvrants. Dans les serrures de porte à double crans, un deuxième contacteur électrique signale la fin de l'opération de verrouillage.The information thus sent by each of the electrical contactors perm and then to the cabin central unit to integrate the fact that all the doors are in the closed state. On receipt of this information, the cabin central unit can then chain another action, for example the locking of the opening. In double-lock door locks, a second electric contactor signals the end of the locking operation.
Le principal défaut connu de ce mode de fonctionnement est lié à la fiabilité des contacteurs électriques. En effet, si une panne arrive sur l'un au m oins de ces contacteurs électriques, aucune information d'état de ferm eture de l'ouvrant ne peut être transm ise au calculateur central. Ainsi, cette unité centrale habitacle ne pourra pas enchaîner une action en m ode de fonctionnem ent nom inal.The main known defect of this mode of operation is related to the reliability of the electrical contactors. In fact, if a failure occurs on one or more of these electrical contactors, no information on the closing state of the opening can be transmitted to the central computer. Thus, this cabin interior unit will not be able to chain an action in operating mode.
Par exem ple, une action de verrouillage des ouvrants ne pourra pas advenir ou bien le calculateur central devra passer dans un m ode de fonctionnem ent dégradé pour faire cette action, ce qui provoquera des défauts en cascade, rendant le diagnostic de la panne difficile.For example, an opening locking action will not be possible or the central computer will have to go into a degraded operating mode to perform this action, which will cause cascading faults, making diagnosis of the fault difficult.
On a donc cherché à améliorer ces dispositifs, pour en augm enter la fiabilité à un coût raisonnable. Le docum ent FR 2857742 propose par exem ple un module capteur (contacteur) pour com m ande de verrouillage/déverrouillage d'un ouvrant de véhicule com prenant deux capteurs fonctionnant avec des principes différents. Ainsi, si l'un des capteurs présente un défaut, l'autre peut assurer la fonction dédiée au module. La fiabilité est ainsi augm entée, et le calculateur avec lequel ce m odule peut échanger des inform ations a une probabilité plus grande de fonctionner en m ode de fonctionnement nom inal.We have therefore sought to improve these devices, to increase reliability at a reasonable cost. For example, document EN 2857742 provides a sensor module (contactor) for locking / unlocking a vehicle opening comprising two sensors operating with different principles. Thus, if one of the sensors has a fault, the other can provide the function dedicated to the module. Reliability is thus increased, and the computer with which this module can exchange information has a greater probability of operating in nominal operating mode.
Cependant, le contrôle du m odule capteur reste assurée par un calculateur, qui peut toujours se retrouver à fonctionner dans un mode de fonctionnem ent dégradé si tous les capteurs d'un même m odule sont en panne. Cette solution présente de plus l'inconvénient de m ultiplier le nombre de capteurs nécessaires, pour chaque serrure d'ouvrant du véhicule et ne résout pas le problèm e de dysfonctionnement éventuel de la liaison entre le m odule capteur de l'ouvrant et le calculateur.However, the control of the sensor module remains ensured by a computer, which can always end up operating in a degraded operating mode if all the sensors of the same module are out of order. This solution also has the disadvantage of multiplying the number of sensors required for each door lock of the vehicle and does not solve the problem of possible malfunction of the connection between the m odule sensor opening and the computer .
Le procédé et le dispositif selon l'invention permettent de pallier ces inconvénients.The method and the device according to the invention make it possible to overcome these disadvantages.
Pour cela, il est prévu dans le cadre de l'invention un procédé de contrôle et de com m ande d'un ouvrant de véhicule, caractérisé en ce que, si aucune inform ation d'état de ferm eture n'a été transm ise entre l'ouvrant et un calculateur depuis un arrêt d'un actionneur de l'ouvrant pendant une période supérieure à une valeur prédéterm inée, on informe le calculateur que l'ouvrant est à l'état ferm é.For this purpose, a method of controlling and controlling a vehicle door is provided in the context of the invention, characterized in that, if no shutdown status information has been transmitted, between the sash and a computer from a shutdown of an actuator of the sash for a period greater than a predetermined value, the computer is informed that the sash is in the closed state.
I l est également prévu dans le cadre de l'invention un dispositif de contrôle et de com m ande d'un ouvrant de véhicule incluant un capteur d'état de ferm eture de l'ouvrant connecté à un calculateur et un actionneur de l'ouvrant caractérisé en ce qu'il comprend des m oyens agencés de sorte que, si aucune information d'état de ferm eture n'a été transm ise entre l'ouvrant et le calculateur depuis un arrêt de l'actionneur de l'ouvrant pendant une période supérieure à une valeur prédéterm inée, on inform e le calculateur que l'ouvrant est à l'état fermé. Le procédé selon l'invention pourra en outre présenter au moins l'une des caractéristiques suivantes :In the context of the invention, a device for controlling and com- pleting a vehicle door including a door opening state sensor connected to a computer and an actuator of the door is also provided. characterized in that it comprises means arranged so that, if no information of closing state has been transmitted between the opening and the computer from a stop of the actuator of the opening during a period greater than a predetermined value, the computer is informed that the opening is in the closed state. The method according to the invention may furthermore have at least one of the following characteristics:
- il com prend en outre une étape consistant à com mander le verrouillage de l'ouvrant depuis le calculateur ; - le calculateur étant un prem ier calculateur, on inform e le prem ier calculateur que l'ouvrant est à l'état fermé depuis un deuxièm e calculateur ; l'actionneur étant un m oteur d'ouvrant motorisé, on détecte la position angulaire de ferm eture de l'ouvrant, puis, si aucune information d'état de ferm eture n'a été transm ise entre l'ouvrant et un calculateur depuis un arrêt du moteur de l'ouvrant pendant une période supérieure à une valeur prédéterm inée, on inform e le calculateur que l'ouvrant est à l'état fermé ; il com prend en outre une étape consistant à com mander le verrouillage de l'ouvrant depuis le deuxièm e calculateur.it further comprises a step of controlling the locking of the door leaf from the computer; the computer being a first calculator, the first computer is informed that the door is in the closed state since a second computer; since the actuator is a motorized opening motor, the angular position of the opening of the door is detected, and then, if no condition information has been transmitted between the door and a computer since stopping the engine of the opening for a period greater than a predetermined value, the computer is informed that the opening is in the closed state; it also includes a step of controlling the locking of the opening from the second computer.
Le dispositif selon l'invention pourra quant à lui en outre présenter au m oins l'une des caractéristiques suivantes : les moyens com prennent un deuxièm e calculateur ;The device according to the invention may furthermore have at least one of the following characteristics: the means comprise a second computer;
- le deuxième calculateur est connecté au calculateur ; - le deuxième calculateur est connecté au capteur ;the second computer is connected to the computer; the second computer is connected to the sensor;
- l'actionneur est connecté à la fois au calculateur et au deuxième calculateur.the actuator is connected to both the computer and the second computer.
D'autres caractéristiques, buts et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre, et en regard des dessins annexés, donnés à titre d'exem ples non lim itatifs et sur lesquels : la figure 1 représente le schéma de principe du dispositif de l'invention selon un prem ier mode de réalisation ; - la figure 2 représente le schéma de principe du dispositif de l'invention selon un deuxièm e m ode de réalisation ; la figure 3 représente le schéma de principe du dispositif de l'invention selon une variante au troisième mode de réalisation ; la figure 4 représente le schém a de principe du dispositif selon l'invention selon une variante au deuxièm e de réalisation de l'invention ; les figures 5 et 6 représentent des schémas de principe de cycles d'ouverture de serrures, à un cran et à deux crans respectivement.Other features, objects and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawings, given as nonlimiting examples and in which: FIG. schematic diagram of the device of the invention according to a first embodiment; FIG. 2 represents the block diagram of the device of the invention according to a second embodiment; Figure 3 shows the block diagram of the device of the invention according to a variant of the third embodiment; Figure 4 shows the schematic diagram of the device according to the invention according to a variant of the second embodiment of the invention; Figures 5 and 6 show schematic diagrams of lock opening cycles, one notch and two notches respectively.
Les figures 1 à 4 représentent le dispositif de l'invention selon différents modes de réalisation de l'invention.Figures 1 to 4 show the device of the invention according to different embodiments of the invention.
Pour ces différents m odes de réalisation, l'architecture générale du dispositif présente de nombreux points com m uns.For these different embodiments, the general architecture of the device has many com m un points.
En effet, pour ces deux modes de réalisation, le m odule 10 de l'ouvrant de véhicule com prend un capteur 1 1 , souvent appelé CPO (Contacteur Porte Ouverte) et un actionneur 12, tous deux connectés à un calculateur 20 par des connexions 31 , 32 respectivem ent. Le capteur 1 1 est adapté pour connaître l'état d'ouverture/ferm eture de l'ouvrant, et est de préférence un contacteur.Indeed, for these two embodiments, the m odule 10 of the vehicle opening comprises a sensor 1 1, often called CPO (Open Door Contactor) and an actuator 12, both connected to a computer 20 by connections 31, 32 respectively. The sensor 1 1 is adapted to know the opening / closing state of the opening, and is preferably a contactor.
Le calculateur 20 est l'unité de contrôle habitacle (calculateur central) . Le calculateur central 20 est par ailleurs connecté à un deuxième calculateur 30 au m oyen d'une connexion 33. Ce deuxièm e calculateur 30 est associé à l'ouvrant.The computer 20 is the cabin control unit (central computer). The central computer 20 is also connected to a second computer 30 through a connection 33. This second computer 30 is associated with the opening.
La connexion 33 permet le transfert d'inform ations m ultiplexées entre les deux calculateurs 20, 30, ces informations étant échangées selon un protocole de com m unication connu sous le nom de CAN (selon l'expression anglo-saxonne « Controller Area Network ») dite « Low Speed Fault Tolérant » ou non lim itativement CAN « High Speed » , ou LI N (selon l'expression anglo-saxonne « Local I nterconnect Network ») , ou FLEXRAY (bus de données haut débit autom obile) .The connection 33 allows the transfer of information m ultiplexed between the two computers 20, 30, this information being exchanged according to a com m unication protocol known as CAN (the English expression "Controller Area Network" ) called "Low Speed Fault Tolerant" or non-it it CAN "High Speed", or LI N (the expression "Local I nterconnect Network"), or FLEXRAY (high speed data bus auto obile).
Le deuxième calculateur 30 est enfin connecté au contacteur électrique 1 1 par l'intermédiaire d'une connexion 34. Cette connexion 34 est reliée à la connexion 31 menant au contacteur 1 1 .The second computer 30 is finally connected to the electric switch 1 1 via a connection 34. This connection 34 is connected to the connection 31 leading to the contactor January 1.
Le contacteur 1 1 est donc relié aux deux calculateurs 20, 30. Dans le cas de serrure à double crans dem andée par les normes européennes relatives aux serrures de coffre à partir de 2009, un deuxième contacteur 1 1 b est relié aux deux calculateurs 20, 30 pour signaler la fin de la phase de verrouillage d'ouvrant (voir figure 3) les liaisons respectives sont 34 et 34b.The contactor 1 1 is therefore connected to the two computers 20, 30. In the case of lock double notches asked by the European standards for safe deposit locks from 2009, a second contactor 1 1 b is connected to the two computers 20, 30 to signal the end of the opening lock phase (see Figure 3) the respective links are 34 and 34b.
Le deuxième mode de réalisation (figure 2) se distingue du prem ier m ode de réalisation (figure 1 ) , car il prévoit en outre une connexion 35 entre le deuxième calculateur 30 et l'actionneur 12. Plus précisém ent, la connexion 35 est reliée à la connexion 32 reliant quant à elle le calculateur central 20 à l'actionneur 12.The second embodiment (FIG. 2) differs from the first embodiment (FIG. 1), since it also provides a connection 35 between the second computer 30 and the actuator 12. More precisely, the connection 35 is connected to the connection 32 connecting the central computer 20 to the actuator 12.
Dans une variante du deuxièm e mode de réalisation, on utilise une serrure avalante à double crans avec deux contacteurs 1 1 et 1 1 b. Le contacteur 1 1 signale le début de fermeture. Le contacteur 1 1 b signale la fin de la phase de verrouillage d'ouvrant (voir figure 4) .In a variant of the second embodiment, use is made of a downstream double-notch lock with two contactors 11 and 11b. The contactor 1 1 signals the beginning of closure. The contactor 1 1 b signals the end of the sash locking phase (see Figure 4).
Dans cette variante du deuxièm e mode de réalisation, un deuxième m oteur 12b peut assurer la phase de verrouillage d'ouvrant. Le moteur 12 n'effectue que la phase d'ouverture d'ouvrant.In this variant of the second embodiment, a second motor 12b can provide the opening lock phase. The motor 12 performs only the opening opening phase.
Les liaisons respectives du moteur 12b sont 32b vers le calculateur 20, et 35b vers le calculateur ouvrant 30.The respective links of the motor 12b are 32b to the computer 20, and 35b to the opening computer 30.
Le calculateur 30 est relié à un capteur de mesure d'angle de la porte de coffre 40. Le capteur d'angle peut être de type relatif, com m e les capteurs à effet Hall, ou peut être de type absolu com me les capteurs à effet magnéto résistif ou potentiométrique.The computer 30 is connected to an angle measurement sensor of the trunk door 40. The angle sensor may be of relative type, such as the Hall effect sensors, or may be of absolute type, such as magneto-resistive or potentiometric effect.
Quel que soit le m ode de réalisation envisagé, il est prévu un logiciel pour gérer les opérations de contrôle et de com m ande du deuxième calculateur 30. L'ouvrant est de préférence une porte de coffre à hayon, l'actionneur 12 pouvant quant à lui être une gâche motorisée, une serrure avalante ou un m oteur d'ouvrant m otorisé.Whatever the embodiment envisaged, there is provided software for managing the control and com m ite operations of the second computer 30. The opening is preferably a hatchback door, the actuator 12 being able to to be a motorized lock, a down-type lock or a motorized door motor.
Nous allons m aintenant décrire le principe de fonctionnement du dispositif selon l'invention. Typiquement, lorsqu'une com m ande à la fermeture d'un ouvrant est activée à la dem ande d'un utilisateur par exem ple, l'actionneur 12 se m et en m arche pour assurer cette ferm eture. En fonctionnement nominal, une fois la fermeture accomplie, l'actionneur 12 s'arrête et le contacteur 11 qui détecte la fermeture effective de l'ouvrant envoie cette information au calculateur central 10, qui peut alors enchaîner d'autres opérations, comme par exemple le verrouillage de l'ouvrant concerné.We will now describe the operating principle of the device according to the invention. Typically, when a com- mander to the closure of an opening is activated at the request of a user for example, the actuator 12 m m and m arche to ensure this fermure. In nominal operation, once the closure is complete, the actuator 12 stops and the contactor 11 which detects the effective closure of the opening sends this information to the central computer 10, which can then chain other operations, such as for example the locking of the opening concerned.
En revanche, si le contacteur 11 est défectueux, ou si la connexion 31 entre le contacteur 11 et le calculateur central 20 est défectueuse ou encore si l'ouvrant n'est pas bien fermé, c'est-à-dire avec un angle d'ouverture faible, aucune information d'état de fermeture de l'ouvrant n'est transmise entre le contacteur 11 et le calculateur central 20.On the other hand, if the contactor 11 is defective, or if the connection 31 between the contactor 11 and the central computer 20 is defective or if the opening is not closed properly, that is to say with an angle d low opening, no closing state of the opening information is transmitted between the contactor 11 and the central computer 20.
Par ailleurs, dans la mesure où le contacteur 11 et le deuxième calculateur 30 sont également connectés l'un à l'autre, le deuxième calculateur 30 sait qu'aucune information n'a été transmise au calculateur central 20. Plus précisément, l'invention prévoit la détermination du temps écoulé t à partir de l'arrêt de l'actionneur 12, et la comparaison de ce temps écoulé à un temps prédéterminé T.Moreover, insofar as the contactor 11 and the second computer 30 are also connected to each other, the second computer 30 knows that no information has been transmitted to the central computer 20. More specifically, the invention provides the determination of the elapsed time t from the shutdown of the actuator 12, and the comparison of this elapsed time to a predetermined time T.
On a illustré sur la figure 5 un cycle d'ouverture pour une serrure à un cran. Sur cette figure, l'état « 1 » indique que le contacteur 11 est fermé, l'état « 0 » indiquant quant à lui qu'il est à l'état ouvert. At = Os, l'actionneur (non représenté) est en marche, mais le contacteur 11 indique un état fermé pour t < T, le temps prédéterminé T étant ici par exemple compris entre 80ms et 100ms (Fig. 5). Le cycle d'ouverture suit alors son cours et le contacteur indique un état ouvert à un temps ultérieur ti.FIG. 5 shows an opening cycle for a one-notch lock. In this figure, the state "1" indicates that the contactor 11 is closed, the state "0" indicating that it is in the open state. At = Os, the actuator (not shown) is running, but the switch 11 indicates a closed state for t <T, the predetermined time T being here for example between 80ms and 100ms (Fig. 5). The opening cycle then follows and the contactor indicates an open state at a later time ti.
On a également illustré sur la figure 6, un cycle d'ouverture pour une serrure à deux crans. Sur cette figure, l'état « 1 » indique que le contacteur 11, 11b signale un état fermé, l'état « 0 » indiquant quant à lui un état ouvert. At = Os, l'actionneur 12 (moteur) est à l'arrêt et les contacteurs 11, 11b indiquent un état fermé. Lorsqu'on commande l'ouverture (par exemple à t = Os), le contacteur 11 envoie un signal après un temps t2 (qui ne dépasse pas typiquement 10ms), permettant le décomptage du temps prédéterminé T, par exemple de l'ordre de T = 67m s. Lorsque t > T, l'actionneur se met alors en m arche pour assurer l'ouverture de l'ouvrant, puis le cycle d'ouverture suit son cours au moins j usqu'à ce que les contacteurs 1 1 , 1 1 b signalent leur état d'ouverture (temps t3 et t4 respectivem ent) . Cette déterm ination est gérée par le deuxièm e calculateur 30, et plus précisément par le logiciel de contrôle et de com mande du calculateur 30 dans lequel le temps prédéterm iné T est inscrit.FIG. 6 also shows an opening cycle for a two-notch lock. In this figure, the state "1" indicates that the contactor 11, 11b signals a closed state, the state "0" indicating meanwhile an open state. At = Os, the actuator 12 (motor) is stopped and the contactors 11, 11b indicate a closed state. When controlling the opening (for example at t = Os), the contactor 11 sends a signal after a time t2 (which does not exceed typically 10ms), allowing the countdown of the predetermined time T, for example of the order of T = 67m s. When t> T, the actuator then moves to open the sash, and the opening cycle continues at least until the contactors 1 1, 1 1 b signal their opening state (time t3 and t4 respectivem ent). This determination is managed by the second computer 30, and more precisely by the computer control and control software 30 in which the predetermined time T is written.
Ainsi, si aucune information d'état de fermeture de l'ouvrant n'est transm ise par le contacteur 1 1 au calculateur central 20 (et donc au deuxième calculateur 30) pendant la durée T, alors le deuxièm e calculateur 30 inform e le calculateur central 20 qu'il doit effectuer l'opération de ferm eture. En variante, le calculateur 30 peut décider de fermer et de verrouiller le hayon, puis informer le calculateur central 20 à l'aide de la liaison 33. Le calculateur central 20 sait alors que l'ouvrant est effectivement à l'état ferm é. Dès lors, le calculateur central 20 peut continuer ses actions, sans engendrer d'erreurs en cascade.Thus, if no information on the closing state of the opening leaf is transmitted by the contactor 11 to the central computer 20 (and therefore to the second computer 30) during the duration T, then the second computer 30 informs the central computer 20 that it must perform the closing operation. Alternatively, the computer 30 may decide to close and lock the tailgate, then inform the central computer 20 by means of the link 33. The central computer 20 then knows that the opening is actually in the closed state. Therefore, the central computer 20 can continue its actions, without generating cascading errors.
Parm i ces actions, et selon le mode de réalisation de la figure 1 , le calculateur central 20 peut par exem ple com mander l'actionneur 12 pour le verrouillage de l'ouvrant.Among these actions, and according to the embodiment of FIG. 1, the central computer 20 may, for example, control the actuator 12 for locking the sash.
Selon le mode de réalisation présenté à l'appui de la figure 2, la com m ande de l'actionneur 12 pour le verrouillage de l'ouvrant peut est effectuée par le deuxièm e calculateur 30 par l'interm édiaire des connexions 35, 32. On notera que le dispositif et le procédé selon l'invention perm et d'obtenir une inform ation redondante sur l'échange ou pas d'informations entre le contacteur 1 1 et le calculateur central 20.According to the embodiment presented in support of FIG. 2, the com m of the actuator 12 for the locking of the opening can is performed by the second computer 30 via the connections 35, 32 Note that the device and the method according to the invention perm and obtain a redundant information on the exchange or no information between the switch 1 1 and the central computer 20.
Bien entendu, de nombreuses fonctionnalités connues en soi peuvent être m ises en œuvre autour de cette architecture générale du dispositif de l'invention. Parm i celles-ci, on peut citer à titre d'exemples non lim itatifs la fermeture centralisée depuis l'intérieur et/ou l'extérieur du véhicule, les vitres électriques, les toits ouvrants ou les toits escamotables (cabriolet) . En variante aux m odes de réalisations présentés à l'appui des figures 1 et 2, les connexions 34, 34b peuvent relier le deuxièm e calculateur 30 au contacteur 1 1 , 1 1 b (non représenté) , sans passer par la connexion 31 . Une telle disposition permet par exemple de savoir si l'absence de transm ission d'information entre le contacteur 1 1 et le calculateur central 20 se tient au niveau du contacteur (contacteur défectueux, porte mal ferm ée) ou au niveau de la connexion 31 . De m anière analogue, en variante au m ode de réalisation de la figure 2, la connexion 35 peut être reliée directement à l'actionneur 12. Lorsque l'actionneur 12 est un m oteur d'ouvrant motorisé, passant de façon automatisée de sa position d'ouverture à sa position de fermeture et inversem ent, on peut doubler la mesure par un capteur de la position angulaire de l'ouvrant (par exemple par un capteur de position du moteur et/ou de comptabilisation du nombre de tours du m oteur) . Ainsi, l'information de fin de course qui est donnée par le contacteur de fermeture de l'ouvrant com m e décrit précédem m ent est égalem ent donnée par le capteur de position angulaire de l'ouvrant. On peut donc comparer ces m esures, et les reboucler l'une par rapport à l'autre pour s'assurer de l'état de ferm eture de l'ouvrant. L'invention n'est pas lim itée aux modes de réalisation décrits ci- dessus, m ais s'étend à tout m ode de réalisation conforme à son esprit, c'est-à-dire dans lequel deux calculateurs quelconques échangent des inform ations entre eux pour la gestion d'un ouvrant de véhicule. Of course, many features known per se can be implemented around this general architecture of the device of the invention. Among these, non-limiting examples include central locking from inside and / or outside the vehicle, power windows, sunroofs or retractable roofs (cabriolet). As an alternative to the methods of embodiment presented in support of FIGS. 1 and 2, the connections 34, 34b can connect the second computer 30 to the contactor 11, 11b (not shown), without passing through the connection 31. Such an arrangement makes it possible, for example, to know whether the absence of transmission of information between the contactor 11 and the central computer 20 is at the level of the contactor (faulty contactor, gate not properly closed) or at the level of the connection 31. . In a similar manner, as an alternative to the embodiment of FIG. 2, the connection 35 can be connected directly to the actuator 12. When the actuator 12 is a motorized opening motor, it switches automatically from its opening position to its closed position and inversem ent, one can double the measurement by a sensor of the angular position of the opening (for example by a motor position sensor and / or counting the number of turns of the m operator). Thus, the end-of-travel information that is given by the closing contactor of the sash as described above is also given by the angular position sensor of the sash. We can therefore compare these measures, and loop them one with respect to the other to ensure the closing state of the opening. The invention is not limited to the embodiments described above, but extends to any method of embodiment in accordance with its spirit, that is to say in which any two computers exchange information. between them for the management of a vehicle opening.
