The device comprises means for detecting (9) the charge applied to the touch-sensitive control surface and means (11) for inhibiting control of the opening and/or closing when the applied charge is outside an acceptable predefined charge range.

Description

La présente invention concerne un dispositif d'activation par surface tactile, d'un mécanisme motorisé d'ouverture et / ou de fermeture d'au mois un ouvrant tel qu'une vitre motorisé, un toit ouvrant, un coffre à assistance de fermeture / ouverture motorisé, un hayon motorisé ou encore une porte latérale coulissante motorisé.The present invention relates to a tactile surface activation device, a motorized opening and / or closing mechanism of at least one opening such as a motorized window, a sunroof, a closing assistance box / motorized opening, a motorized tailgate or a motorized sliding side door.

Il est usuel pour la commande de ces organes de prévoir un dispositif de manoeuvre sous forme de commutateurs ou parfois d'une manette actionnable dans quatre directions, souvent appelée "joystick".It is customary for the control of these members to provide a maneuvering device in the form of switches or sometimes a joystick operable in four directions, often called "joystick".

On a proposé aussi, plus récemment, d'utiliser pour ces commandes des surfaces tactiles permettant de détecter un appui simple du doigt du conducteur et, en fonction de la position en X, Y de l'appui détecté et/ou du déplacement ultérieur de cet appui sur la surface, de déclencher un type particulier d'action ou de commande d'organe du véhicule. On pourra se référer par exemple aux documents FR 2 798 329 , FR 2 800 885 et US 6 157 372 . Ces surfaces tactiles peuvent être de tout type et utiliser différentes technologies.It has also been proposed, more recently, to use for these commands tactile surfaces making it possible to detect a simple support of the driver's finger and, depending on the X, Y position of the detected support and / or the subsequent displacement of this support on the surface, to trigger a particular type of action or vehicle organ control. For example, documents may be referred to FR 2 798 329 , FR 2,800,885 and US 6,157,372 . These touch surfaces can be of any type and use different technologies.

Si l'utilisation de telles surfaces tactiles va indiscutablement dans le sens d'une meilleure convivialité et d'une compacité accrue des dispositifs de commande, elle peut accroître en revanche le risque d'erreurs de commande non intentionnelle.While the use of such touch surfaces is indisputable in the sense of improved usability and increased compactness of the control devices, it can increase the risk of unintentional control errors.

Ainsi, dans le cadre des ouvrants motorisés tels que les vitres, le toit ouvrant ou encore le coffre et ou le hayon arrière, on est contraint de traiter l'aspect sécuritaire, en particulier lors de la fermeture de l'ouvrant.Thus, in the context of motorized openings such as windows, the sunroof or the trunk and or the tailgate, it is forced to treat the security aspect, especially when closing the opening.

Cette problématique est plus largement connue sous l'appellation « anti-pincement » et est relative au danger que présente un ouvrant en cours de fermeture en particulier pour le membre d'un utilisateur placé sur le parcours de fermeture et constituant un risque de pincement du membre.This problem is more widely known under the name "anti-pinch" and is related to the danger of an opening during closing especially for the member of a user placed on the closing course and constituting a risk of pinching the member.

A ce jour, de nombreuses solutions ont été proposées pour détecter qu'un objet se trouve sur le parcours de fermeture de l'ouvrant.To date, many solutions have been proposed to detect that an object is on the closing path of the opening.

Ces solutions traitent généralement la détection d'une résistance à la fermeture qui est assimilée à ce qu'un objet bloque la fermeture d'un ouvrant et on arrête le moteur d'entraînement pour prévenir plus de dommages matériels et corporels. Il s'agit donc d'un traitement direct d'un problème par des moyens mécaniques et électroniques complexes et coûteux.These solutions generally deal with the detection of a closing resistance which is likened to an object blocking the closing of an opening and stopping the drive motor to prevent more damage to property and body. It is therefore a direct treatment of a problem by complex and expensive mechanical and electronic means.

La Demanderesse a constaté qu'une gestion préventive des commandes des ouvrants peut apporter une amélioration significative, en particulier en relation avec les surfaces tactiles susmentionnées, pour la sécurité passive.The Applicant has found that a preventive management of the controls of the opening can bring a significant improvement, in particular in relation to the aforementioned tactile surfaces, for the passive safety.

Le but de l'invention est de proposer une nouvelle solution pour un dispositif d'activation par surface tactile d'un mécanisme motorisé d'ouverture et/ou de fermeture d'un ouvrant permettant d'accroître la sécurité passive de commande.The object of the invention is to propose a new solution for a tactile surface activation device of a motorized opening and / or closing mechanism of an opening for increasing passive control safety.

A cet effet, l'invention a pour objet un dispositif d'activation par surface tactile d'un mécanisme motorisé d'ouverture et/ou de fermeture d'un ouvrant, comportant une surface tactile de commande de l'ouverture et / ou de la fermeture d'au moins un ouvrant, caractérisé en ce qu'il comprend des moyens de détection de la charge appliquée à ladite surface tactile de commande et des moyens d'inhibition de la commande d'ouverture et/ou fermeture lorsque la charge appliquée est en dehors d'une plage admissible de charge prédéfinie.For this purpose, the subject of the invention is a tactile surface activation device for a motorized mechanism for opening and / or closing an opening, comprising a tactile surface for controlling the opening and / or the closing of at least one opening, characterized in that it comprises means for detecting the load applied to said touching control surface and means for inhibiting the opening and / or closing control when the load applied is outside a predefined allowable load range.

  • la figure 1 est un schéma d'un dispositif d'activation par surface tactile d'un premier mode de réalisation de surface tactile selon l'invention,
  • la figure 2 est un schéma synoptique du dispositif de la figure 1,
  • la figure 3 est un schéma d'un autre mode de réalisation de la partie surface tactile du dispositif d'activation selon l'invention.
Other advantages and characteristics will appear on reading the description of the invention, as well as the appended drawings in which:
  • the figure 1 is a diagram of a tactile surface activation device of a first tactile surface embodiment according to the invention,
  • the figure 2 is a synoptic diagram of the device of the figure 1 ,
  • the figure 3 is a diagram of another embodiment of the tactile surface portion of the activation device according to the invention.

La figure 1 montre de façon schématique un dispositif 1 d'activation par surface tactile d'un mécanisme motorisé (non représenté) d'ouverture et/ou de fermeture d'un ouvrant, tel que par exemple une vitre d'un véhicule automobile, un toit ouvrant ou encore le coffre / hayon / porte coulissante motorisé d'un véhicule.The figure 1 shows schematically a device 1 activation by tactile surface of a motorized mechanism (not shown) opening and / or closing a opening, such as for example a window of a motor vehicle, a sunroof or the trunk / tailgate / motorized sliding door of a vehicle.

Le dispositif comporte une surface tactile de commande 3 de l'ouverture et / ou de la fermeture d'au moins un ouvrant, accessible pour un utilisateur, en particulier un doigt de celui-ci, par un mouvement de haut en bas, c'est-à-dire en exerçant une certaine pression sur la surface tactile du capteur. Sa première destination est de localiser l'endroit du toucher en coordonnées X et/ou Y (représenté sur le repère - la direction Z étant perpendiculaire à ces deux directions X et Y).The device comprises a touch control surface 3 of the opening and / or closure of at least one opening, accessible to a user, in particular a finger thereof, by a movement from top to bottom, it is that is to say by exerting a certain pressure on the touch surface of the sensor. Its first destination is to locate the location of the touch in X and / or Y coordinates (represented on the coordinate system - the direction Z being perpendicular to these two directions X and Y).

La surface tactile peut être, énumérée de façon non exhaustive et non limitative, un capteur tactile à matrice de résistances, un capteur capacitif matriciel, un capteur matriciel de pression ou encore une matrice / série de contacts individuels placés sous une couche d'un matériau élastique de manière qu'un appui sur la couche « tactile » actionne un ou plusieurs des contacts individuels dont le changement d'état est exploité pour la commande.The touch surface may be, enumerated in a non-exhaustive and nonlimiting manner, a touch sensor with a resistance matrix, a capacitive matrix sensor, a pressure matrix sensor or a matrix / series of individual contacts placed under a layer of a material. elastic so that a support on the "touch" layer actuates one or more individual contacts whose change of state is used for the command.

Sur la surface supérieure 3 de la surface tactile sont représentés des pictogrammes sous forme de flèches, où la flèche 5 indique une zone permettant de fermer la vitre et la flèche 7 indique une zone pour ouvrir la vitre.On the upper surface 3 of the tactile surface are represented pictograms in the form of arrows, where the arrow 5 indicates an area for closing the window and the arrow 7 indicates a zone to open the window.

En relation avec le schéma synoptique de la figure 2 représentant un premier mode de réalisation de l'invention, le dispositif 1 comprend des moyens 9 de détection de la charge appliquée à ladite surface tactile de commande et des moyens 11 d'inhibition de la commande d'ouverture et/ou fermeture lorsque la charge appliquée est en dehors d'une plage admissible de charge prédéfinie.In relation to the synoptic diagram of the figure 2 representing a first embodiment of the invention, the device 1 comprises means 9 for detecting the load applied to said touch control surface and means 11 for inhibiting the opening and / or closing control when the load applied is outside a predefined permissible load range.

De façon préférentielle, le capteur tactile est choisi de manière de non seulement détecter le toucher d'un utilisateur pour en extraire la localisation en coordonnées X et/ou Y, mais aussi un paramètre proportionnel à la charge appliquée sur la surface tactile. Dans ce cas, il présente une sortie 13 d'un signal proportionnel à la charge appliquée. Ce signal de sortie est appliqué à l'entrée d'une unité de comparaison 21 et compare ce signal avec des valeurs de charge appliquées enregistrées dans une mémoire 23. Le signal de sortie de l'unité de comparaison 21 correspondant à une information, par exemple binaire, indiquant que la charge appliquée sur la surface est dans la plage autorisée ou non.Preferably, the touch sensor is selected so as not only to detect the touch of a user to extract the location in X and / or Y coordinates, but also a parameter proportional to the load applied to the touch surface. In this case, it has an output 13 of a signal proportional to the applied load. This output signal is applied to the input of a comparison unit 21 and compares this signal with applied load values stored in a memory 23. The output signal of the comparison unit 21 corresponding to information, for example binary, indicating that the charge applied to the surface is within the allowed range or not.

Selon la figure 2, le capteur possède en outre deux sorties 15 et 17 correspondant à des signaux permettant de localiser des coordonnées X et/ou Y sur la surface du capteur pour localiser l'endroit touché par l'utilisateur, et donc de produire, en fonction des coordonnées reçues en X et Y dans une unité de traitement 19 la commande appropriée pour ouvrir ou fermer l'ouvrant en question.According to figure 2 , the sensor furthermore has two outputs 15 and 17 corresponding to signals making it possible to locate X and / or Y coordinates on the surface of the sensor in order to locate the location touched by the user, and thus to produce, as a function of the coordinates received in X and Y in a processing unit 19 the appropriate command to open or close the opening in question.

Aussi bien la sortie de l'unité de traitement 19 que la sortie de l'unité de comparaison 21 est appliquée à des entrées correspondantes de l'unité d'inhibition 11.Both the output of the processing unit 19 and the output of the comparison unit 21 is applied to corresponding inputs of the inhibition unit 11.

Si donc cette unité 11 reçoit depuis l'unité de comparaison 21 un signal indiquant que la charge appliquée est en dehors de la plage de charge admissible, elle inhibe le signal de commande, de sorte que les ouvrants concernés restent immobiles.If therefore this unit 11 receives from the comparison unit 21 a signal indicating that the applied load is outside the allowable load range, it inhibits the control signal, so that the openings concerned remain stationary.

En revanche, si la charge appliquée se trouve dans la plage admissible, le signal de commande transite par l'unité 11 et l'ouvrant va réaliser le mouvement demandé.On the other hand, if the applied load is in the admissible range, the control signal passes through the unit 11 and the opening will carry out the requested movement.

Ainsi, toute commande intempestive, par exemple le pied d'un enfant montant sur la porte dans laquelle le dispositif d'activation est intégré, n'est pas transmise, ce qui augmente considérablement la sécurité passive, c'est-à-dire la prévention d'une commande non désirable.Thus, any untimely control, for example the foot of a child mounting on the door in which the activation device is integrated, is not transmitted, which greatly increases the passive safety, that is to say the prevention of an undesirable order.

La limite inférieure de la plage admissible peut être de 0g, mais de préférence, on choisit une limite inférieure de la dite plage admissible correspondant à la charge d'un poids d'environ 30g, ce qui évite qu'un effleurement de la surface tactile conduit à une commande intempestive.The lower limit of the allowable range may be 0g, but preferably, a lower limit of said permissible range corresponding to the load of a weight of about 30g is chosen, which avoids a touch of the touch surface leads to an untimely command.

De préférence, on choisit la limite supérieure de la dite plage admissible correspondant à la charge d'un poids d'environ 3kg. Ainsi, un fort appui intempestif ne conduit pas à un mouvement intempestif de l'ouvrant.Preferably, the upper limit of the said admissible range corresponding to the load of a weight of about 3 kg is chosen. Thus, a strong inadvertent support does not lead to an untimely movement of the opening.

Bien entendu, le paramètre reflétant la charge en appui sur la surface tactile peut être la pression, une flexion (aussi appelé la flèche) ou tout autre paramètre équivalent.Of course, the parameter reflecting the load on the touch surface can be the pressure, a bending (also called the arrow) or any other equivalent parameter.

Selon un second mode de réalisation représenté sur la figure 3, la surface tactile est montée de façon qu'une charge appliquée provoque un déplacement prédéfini de ladite surface. On comprend donc la surface tactile 3 est montée avec une certaine mobilité possible, soit un déplacement en Z (voir flèche sur la figure 3), soit un certain mouvement de pivotement ou encore une certaine déformation / flexion de la surface, ce qui conduit à ce que ledit déplacement prédéfini peut être un mouvement de translation paralèlle à la normale de la surface tactile, un mouvement de pivotement de la surface tactile ou encore une flexion de ladite surface tactile.According to a second embodiment shown on the figure 3 , the touch surface is mounted so that an applied load causes a predefined displacement of said surface. So we understand the touch surface 3 is mounted with some possible mobility, ie a displacement in Z (see arrow on the figure 3 ), or a certain pivoting movement or a certain deformation / bending of the surface, which leads to that said predefined displacement can be a parallel translational movement to the normal of the touch surface, a pivoting movement of the surface tactile or even a flexion of said touch surface.

Les moyens de détection de ladite charge appliquée comprennent, placés en dessous de ladite surface tactile 3, d'une part un moyen élastique 30, un ressort, de préférence hélicoïdale ou une butée élastique, de préférence en caouthouc, et d'autre part un interrupteur 32 pour inhiber la commande d'ouverture et/ou de fermeture de l'ouvrant, de manière qu'en cas d'application d'une charge supérieure à la limite supérieure de ladite plage admissible, ladite surface tactile déforme ledit moyen élastique et provoque l'actionnement dudit interrupteur.The means for detecting said applied load comprise, placed beneath said tactile surface 3, on the one hand an elastic means 30, a spring, preferably a helical spring or an elastic stop, preferably made of rubber, and on the other hand a switch 32 to inhibit the opening and / or closing control of the sash, so that when a load greater than the upper limit of said allowable range is applied, said touch surface deforms said elastic means and causes the actuation of said switch.

Lorsque l'interrupteur est actionné, le signal de commande est inhibé et l'ouvrant reste immobile malgré l'application d'une charge sur la surface tactile.When the switch is actuated, the control signal is inhibited and the opening remains stationary despite the application of a load on the touch surface.

Dans un perfectionnenemnt préférentiel, c'est la résistance élastique de l'interrupteur pour réaliser la fermeture de celui-ci qui forme ledit moyen élastique 30. On comprend donc que la charge nécessaire à l'actionnement de l'interrupteur est dimensionnée de manière que lesdits moyens élastiques sont formés par l'interrupteur lui-même.In a perfectionnenemnt preferential, it is the resilient resistance of the switch to achieve the closure thereof which forms said resilient means 30. It is therefore understood that the load required for the actuation of the switch is dimensioned so that said elastic means are formed by the switch itself.

Dans ce cas, l'interrupteur est donc dimmensionné de manière que seule une charge supérieure à la limite supérieure de ladite plage admissible parvient à l'actionner. Avantageusement, pour ce perfectionnement, l'interrupteur est un interrupteur à lame élastique de contactage.In this case, the switch is dimmensioned so that only a load greater than the upper limit of said allowable range manages to operate. Advantageously, for this improvement, the switch is an elastic contact blade switch.

Bien entendu, pour que l'interrupteur puisse inhiber la commande d'ouvertuer et / ou de fermeture, il suffit qu'il y ait un changement d'état de l'interrupteur de l'ouverture vers la fermeture ou vice-versa.Of course, for the switch to inhibit the command to open and / or close, it is sufficient that there is a change of state of the switch from opening to closing or vice versa.
