The invention relates in particular to a method for managing the positioning of a screen arranged in the passenger compartment of a motor vehicle, said screen being fixed to a support in front of the front passenger seat, said support being secured to a jack capable of moving between a deployed position, in which the screen is in front of the dashboard of the vehicle, and a contracted position, in which the front surface of the screen is flush with the dashboard.

État de la technique antérieure State of the prior art
On sait qu’il est courant de nos jours d’équiper les véhicules automobiles d’écrans agencés dans l’habitacle des véhicules. On sait aussi que, pour des raisons d’ergonomie et de confort d’utilisation des véhicules, les constructeurs automobiles souhaitent désormais agencer des écrans en divers endroits de l’habitacle des véhicules, notamment devant la place du passager avant. Et, du côté du passager avant d’un véhicule automobile, en d’autres termes à la place voisine du poste de conduite d’un véhicule actuel, il s’avère judicieux pour des raisons d’ergonomie de positionner l’écran destiné à être utilisé par le passager devant la planche de bord du véhicule à une hauteur qui permet au passager de regarder l’écran de manière confortable. It is known that it is common these days to equip motor vehicles with screens arranged in the passenger compartment of the vehicles. We also know that, for reasons of ergonomics and comfort of use of vehicles, automobile manufacturers now wish to arrange screens in various places in the vehicle interior, in particular in front of the front passenger seat. And, on the side of the front passenger of a motor vehicle, in other words in the place close to the driving position of a current vehicle, it proves to be judicious for reasons of ergonomics to position the screen intended for be used by the passenger in front of the vehicle's dashboard at a height that allows the passenger to view the screen comfortably.
Cependant, en cas d’accident, la présence d’un écran à cet endroit peut venir perturber le fonctionnement de l’airbag passager de l’appareillage de sécurité passive qui équipe aujourd’hui la plupart des véhicules automobiles. En effet, lorsqu’il est déclenché, l’airbag passager se gonfle généralement d’une manière telle qu’au moins sa partie inférieure prend appui sur la planche de bord devant le passager afin d’amortir plus efficacement le passager au cas où celui-ci se verrait projeté en avant par le choc. Ainsi, on comprend que la présence d’un écran agencé devant la planche de bord peut nuire à cette particularité du déploiement de l’airbag passager d’un véhicule automobile, en risquant même, au pire, de crever l’airbag lors de son déploiement. However, in the event of an accident, the presence of a screen in this location may disrupt the operation of the passenger airbag of the passive safety equipment fitted to most motor vehicles today. Indeed, when triggered, the passenger airbag generally inflates in such a way that at least its lower part rests on the dashboard in front of the passenger in order to cushion the passenger more effectively in the event that the passenger -it would be projected forward by the shock. Thus, it is understood that the presence of a screen arranged in front of the dashboard can harm this particularity of the deployment of the passenger airbag of a motor vehicle, even risking, at worst, to burst the airbag during its deployment.
Résumé de l’invention Summary of the Invention
L’invention vise à pallier cet inconvénient. L’invention a en effet pour but de fournir une solution pour, dans un véhicule automobile, pouvoir avoir un écran agencé devant la place du passager avant, et ce sans nuire aucunement au fonctionnement de l’airbag passager du véhicule. Ce but est atteint, selon un premier objet de l’invention, au moyen d’un procédé de gestion, par un système informatique (100) embarqué à bord d’un véhicule automobile, du positionnement d’un écran agencé dans l’habitacle du véhicule, ledit écran étant fixé sur un support devant la place du passager avant, ledit support étant solidaire d’un vérin capable de se mouvoir entre une position déployée, dans laquelle l’écran se trouve devant la planche de bord du véhicule, et une position contractée, dans laquelle la surface frontale de l’écran affleure avec la planche de bord, le procédé comprenant les étapes de : i) déterminer si un signal électrique est généré par un appareillage de sécurité passive du véhicule ; et, lorsqu’il est établi que tel est le cas, ii) provoquer le déplacement du vérin de sa position déployée vers sa position contractée. The invention aims to overcome this drawback. The object of the invention is in fact to provide a solution for, in a motor vehicle, being able to have a screen arranged in front of the front passenger seat, and this without harming in any way the operation of the passenger airbag of the vehicle. This object is achieved, according to a first object of the invention, by means of a management method, by a computer system (100) on board a motor vehicle, of the positioning of a screen arranged in the passenger compartment of the vehicle, said screen being fixed to a support in front of the front passenger seat, said support being secured to a jack capable of moving between a deployed position, in which the screen is in front of the dashboard of the vehicle, and a contracted position, in which the front surface of the screen is flush with the dashboard, the method comprising the steps of: i) determining whether an electrical signal is generated by a passive safety device of the vehicle; and, when it is established that this is the case, ii) cause the movement of the actuator from its extended position to its contracted position.
Selon une variante, l’étape ii) peut comprendre une étape consistant à déclencher un dispositif pyrotechnique connecté au vérin. According to a variant, step ii) can comprise a step consisting in triggering a pyrotechnic device connected to the actuator.
Selon une autre variante, l’étape ii) peut être réalisée de telle sorte que la surface frontale de l’écran affleure avec la planche de bord au moment où un airbag passager de l’appareillage de sécurité passive est complètement gonflé, si bien qu’au moins une partie inférieure de l’airbag peut prendre appui sur l’écran. According to another variant, step ii) can be carried out in such a way that the front surface of the screen is flush with the dashboard when a passenger airbag of the passive safety device is completely inflated, so that at least a lower part of the airbag can press against the screen.
Selon une autre variante, l’étape ii) peut provoquer le déplacement d’une portion de la planche de bord solidaire du vérin en laissant un espace libre dans lequel l’écran se loge lorsque sa surface frontale affleure avec la planche de bord. According to another variant, step ii) can cause the displacement of a portion of the dashboard secured to the actuator, leaving a free space in which the screen is housed when its front surface is flush with the dashboard.
En outre, l’invention a également pour objet un système pour gérer le positionnement d’un écran agencé dans l’habitacle d’un véhicule automobile, ledit écran étant fixé sur un support devant la place du passager avant, ledit support étant solidaire d’un vérin capable de se mouvoir entre une position déployée, dans laquelle l’écran se trouve devant une planche de bord du véhicule, et une position contractée, dans laquelle la surface frontale de l’écran affleure avec la planche de bord, le système comprenant au moins une unité de traitement d’informations, comprenant au moins un processeur, et un support de stockage de données configurés pour mettre en œuvre un procédé tel que décrit ci-dessus. De plus, l’invention a aussi pour objet un programme comprenant des instructions de code de programme pour l’exécution des étapes d’un procédé tel que décrit ci-dessus lorsque ledit programme est exécuté sur un ordinateur et/ou un processeur. Par ailleurs, l’invention a également pour objet un support utilisable dans un ordinateur sur lequel un programme tel que décrit ci-dessus est enregistré. In addition, the invention also relates to a system for managing the positioning of a screen arranged in the passenger compartment of a motor vehicle, said screen being fixed on a support in front of the front passenger seat, said support being integral with a jack capable of moving between an extended position, in which the screen is in front of a dashboard of the vehicle, and a contracted position, in which the front surface of the screen is flush with the dashboard, the system comprising at least one information processing unit, comprising at least one processor, and a data storage medium configured to implement a method as described above. In addition, the invention also relates to a program comprising program code instructions for the execution of the steps of a method as described above when said program is executed on a computer and/or a processor. Furthermore, the invention also relates to a medium that can be used in a computer on which a program as described above is recorded.
Enfin, l’invention a aussi pour objet un véhicule automobile comprenant un système tel que décrit ci-dessus. Finally, the invention also relates to a motor vehicle comprising a system as described above.

Selon l’invention, un système 100 pour gérer le positionnement d’un écran agencé dans l’habitacle d’un véhicule automobile, ledit écran étant fixé sur un support devant la place du passager avant, ledit support étant solidaire d’un vérin capable de se mouvoir entre une position déployée, dans laquelle l’écran se trouve devant la planche de bord du véhicule, et une position contractée, dans laquelle la surface frontale de l’écran affleure avec la planche de bord, est un système informatique, représenté à la figure 1, qui comprend une unité de traitement d’informations 101, comprenant un ou plusieurs processeurs, un support de stockage de données 102, au moins une interface d’entrée et sortie 103, permettant la réception de données (et/ou signaux) et l’émission de données (et/ou signaux). Selon certains modes de réalisation, le système 100 selon l’invention est embarqué dans un véhicule automobile (e.g. voitures, poids lourds, autobus, véhicules utilitaires, etc.) et il est hébergé sur un ou plusieurs des calculateurs, unités de commande électroniques et/ou autres boîtiers télématiques du véhicule. Selon d’autres modes de réalisation, le système 100 selon l’invention est hébergé sur un calculateur d’un véhicule automobile et il interagit par le biais de son interface d’entrée et sortie 103 avec un calculateur d’un appareillage de sécurité passive du véhicule. Selon le mode de réalisation préféré, le système 100 selon l’invention fait partie intégrante d’un calculateur d’un appareillage de sécurité passive d’un véhicule automobile, qui, de manière traditionnelle, comprend au moins un capteur de détection de collision apte à générer au moins un signal électrique lors d’une collision et au moins un airbag passager, en d’autres termes un airbag qui se déploie devant la place voisine du poste de conduite lorsqu’un signal électrique est généré par le capteur. De plus, un appareillage de sécurité passive d’un véhicule automobile au sens de la présente invention comprend avantageusement un vérin, préférentiellement fixé à une traverse de la planche de bord du véhicule, couplé à un dispositif pyrotechnique et solidaire d’un support sur lequel un écran est fixé devant la place du passager avant, qui, lors du déclenchement du dispositif pyrotechnique, se meut entre une position déployée, dans laquelle l’écran se trouve devant la planche de bord, et une position contractée, dans laquelle la surface frontale de l’écran affleure avec la planche de bord. Ainsi, grâce à ces moyens, le système 100 selon l’invention est avantageusement en mesure de déterminer si un signal électrique est généré par un appareillage de sécurité passive d’un véhicule automobile lors de la détection d’une collision et, en déclenchant le dispositif pyrotechnique, de provoquer le déplacement du vérin de sa position déployée vers sa position contractée. Selon l’invention, tous les éléments décrits ci-dessus contribuent donc pour permettre au système 100 selon l’invention de mettre en œuvre un procédé de gestion du positionnement d’un écran agencé dans l’habitacle du véhicule, ledit écran étant fixé sur un support, devant la place du passager avant, ledit support étant solidaire d’un vérin capable de se mouvoir entre une position déployée, dans laquelle l’écran se trouve devant la planche de bord du véhicule, et une position contractée, dans laquelle la surface frontale de l’écran affleure avec la planche de bord, tel que décrit ci-dessous en lien avec les figure 2 et 3. According to the invention, a system 100 for managing the positioning of a screen arranged in the passenger compartment of a motor vehicle, said screen being fixed to a support in front of the front passenger seat, said support being secured to a cylinder capable to move between a deployed position, in which the screen is in front of the dashboard of the vehicle, and a contracted position, in which the front surface of the screen is flush with the dashboard, is a computer system, represented in FIG. 1, which comprises an information processing unit 101, comprising one or more processors, a data storage medium 102, at least one input and output interface 103, allowing the reception of data (and/or signals) and the transmission of data (and/or signals). According to certain embodiments, the system 100 according to the invention is embedded in a motor vehicle (eg cars, trucks, buses, utility vehicles, etc.) and it is hosted on one or more of the computers, control units electronics and/or other vehicle telematics units. According to other embodiments, the system 100 according to the invention is hosted on a computer of a motor vehicle and it interacts through its input and output interface 103 with a computer of a passive safety device of the vehicle. According to the preferred embodiment, the system 100 according to the invention forms an integral part of a computer of a passive safety device of a motor vehicle, which, traditionally, comprises at least one collision detection sensor capable to generate at least one electrical signal during a collision and at least one passenger airbag, in other words an airbag which deploys in front of the seat adjacent to the driving position when an electrical signal is generated by the sensor. In addition, a passive safety device for a motor vehicle within the meaning of the present invention advantageously comprises a jack, preferably fixed to a crosspiece of the dashboard of the vehicle, coupled to a pyrotechnic device and secured to a support on which a screen is fixed in front of the seat of the front passenger, who, when the pyrotechnic device is triggered, moves between a deployed position, in which the screen is in front of the dashboard, and a contracted position, in which the frontal surface of the screen is flush with the dashboard. Thus, thanks to these means, the system 100 according to the invention is advantageously able to determine whether an electrical signal is generated by a passive safety device of a motor vehicle upon detection of a collision and, by triggering the pyrotechnic device, to cause the actuator to move from its extended position to its contracted position. According to the invention, all the elements described above therefore contribute to enabling the system 100 according to the invention to implement a method for managing the positioning of a screen arranged in the passenger compartment of the vehicle, said screen being fixed on a support, in front of the front passenger seat, said support being secured to a jack capable of moving between an extended position, in which the screen is in front of the dashboard of the vehicle, and a contracted position, in which the the front surface of the screen is flush with the dashboard, as described below in connection with figures 2 and 3.
Selon une première étape 201 du procédé selon l’invention, le système 100 selon l’invention détermine si un signal électrique est généré par un appareillage de sécurité passive du véhicule. Pour ce faire, le système 100 selon l’invention a recours à son interface d’entrée et sortie 103 pour déterminer si le capteur de détection de collision de l’appareillage de sécurité passive du véhicule génère un signal électrique. Et, lorsque qu’il établit que tel est le cas, le système selon l’invention réalise une seconde étape 202 du procédé selon l’invention au cours de laquelle il provoque le déplacement du vérin de sa position déployée vers sa position contractée, en déclenchant le dispositif pyrotechnique couplé au vérin. Plus spécifiquement, en référence à la figure 3 qui illustre des vues de côté de la place du passager avant derrière le pare-brise 300 du véhicule, une situation normale est présentée dans le cadre de gauche, dans laquelle l’écran 301 agencé devant la place du passager avant est fixé à un support (non détaillé) solidaire du vérin 302 de l’appareillage de sécurité passive du véhicule, qui se trouve à ce stade dans sa position déployée si bien que l’écran 301 se trouve devant la planche de bord 303 du véhicule. A ce stade, l’airbag passager 304 est complètement fermé. Ensuite, dans le cadre du milieu, qui illustre la situation au cours de la réalisation de la deuxième étape 202 du procédé selon l’invention, càd. la situation qui se produit lorsqu’un signal électrique a été généré par le capteur de détection de collision lors d’un choc, le système 100 selon l’invention a déclenché le dispositif pyrotechnique (non représenté) et le vérin 302 amorce son déplacement de sa position déployée vers sa position contractée. Simultanément, l’appareillage de sécurité passive déclenche le déploiement de l’airbag passager 304. Ainsi, la réalisation de cette deuxième étape 202 provoque avantageusement le déplacement d’une portion 305 de la planche de bord 303 solidaire du vérin 302 en laissant un espace libre 306 dans lequel va se loger l’écran au terme de la deuxième étape 202 du procédé selon l’invention. Enfin, dans le cadre de droite, qui illustre la situation lorsque la deuxième étape 202 du procédé selon l’invention est complètement réalisée, le vérin 302 est dans sa position contractée et la surface frontale de l’écran 301 affleure avec la planche de bord 303 en se logeant avantageusement dans l’espace libre 306 laissé par le retrait de la portion 305 de la planche de bord 303. Ainsi, de manière avantageuse, la surface frontale de l’écran 301 affleure avec la planche de bord 303 au moment où l’airbag passager est complètement gonflé (i.e. déployé), si bien qu’au moins une partie inférieure 307 de l’airbag passager 304 peut prendre appui sur l’écran 301. Par conséquent, aux termes du procédé et du système selon l’invention décrits ci-dessus, une solution est fournie pour permettre l’agencement d’un écran devant la place du passager avant d’un véhicule automobile sans nuire au bon fonctionnement d’un appareillage de sécurité passive du véhicule. According to a first step 201 of the method according to the invention, the system 100 according to the invention determines whether an electrical signal is generated by passive safety equipment of the vehicle. To do this, the system 100 according to the invention uses its input and output interface 103 to determine whether the collision detection sensor of the vehicle's passive safety equipment generates an electrical signal. And, when it establishes that this is the case, the system according to the invention carries out a second step 202 of the method according to the invention during which it causes the movement of the actuator from its extended position to its contracted position, by triggering the pyrotechnic device coupled to the cylinder. More specifically, with reference to FIG. 3 which illustrates side views of the front passenger seat behind the windshield 300 of the vehicle, a normal situation is shown in the left frame, in which the screen 301 arranged in front of the place of front passenger is fixed to a support (not detailed) secured to the cylinder 302 of the passive safety equipment of the vehicle, which is at this stage in its deployed position so that the screen 301 is in front of the dashboard 303 of the vehicle. At this point, the passenger airbag 304 is completely closed. Then, in the middle frame, which illustrates the situation during the execution of the second step 202 of the method according to the invention, ie. the situation that occurs when an electrical signal has been generated by the collision detection sensor during an impact, the system 100 according to the invention has triggered the pyrotechnic device (not shown) and the actuator 302 begins its movement from its extended position to its contracted position. Simultaneously, the passive safety device triggers the deployment of the passenger airbag 304. Thus, carrying out this second step 202 advantageously causes the displacement of a portion 305 of the dashboard 303 secured to the actuator 302, leaving a space free 306 in which the screen will be housed at the end of the second step 202 of the method according to the invention. Finally, in the right frame, which illustrates the situation when the second step 202 of the method according to the invention is completely carried out, the cylinder 302 is in its contracted position and the front surface of the screen 301 is flush with the dashboard. 303 advantageously being housed in the free space 306 left by the removal of the portion 305 of the dashboard 303. Thus, advantageously, the front surface of the screen 301 is flush with the dashboard 303 when the passenger airbag is fully inflated (ie deployed), so that at least a lower part 307 of the passenger airbag 304 can rest on the screen 301. Consequently, under the terms of the method and the system according to the invention described above, a solution is provided to allow the arrangement of a screen in front of the front passenger seat of a motor vehicle without impairing the proper functioning of vehicle passive safety equipment.
