Description

Bouton et dispositif de commande multifonction  Button and multifunction control device
La présente invention concerne un bouton de commande multifonction apte à commander plusieurs fonctions d'un véhicule automobile avec un seul organe de commande. La présente invention concerne également un dispositif de commande multifonction associé.  The present invention relates to a multifunction control button adapted to control several functions of a motor vehicle with a single control member. The present invention also relates to an associated multifunction control device.
Dans le domaine automobile, les commandes de divers organes électriques sont réalisées classiquement par des commutateurs / interrupteurs. Toutefois, au vu du nombre croissant d'organes électriques à commander, des dispositifs de commande multifonction, c'est-à-dire aptes à commander plusieurs fonctions avec un seul organe de commande, sont de plus en plus utilisés du fait des avantages ergonomiques qui en résultent.  In the automotive field, the controls of various electrical components are conventionally performed by switches / switches. However, in view of the increasing number of electrical components to be controlled, multifunction control devices, that is to say, able to control several functions with a single controller, are increasingly used because of the ergonomic benefits resulting from it.
Par exemple, à partir d'un seul organe de commande, réalisé sous la forme d'un joystick, associé à un écran d'affichage, on peut commander le système de navigation ou se déplacer dans des menus déroulants de l'écran d'affichage, pour commander les fonctions de climatisation comme la température ou l'intensité de la ventilation, du système audio comme le volume.  For example, from a single control member, made in the form of a joystick, associated with a display screen, it is possible to control the navigation system or to move in drop-down menus of the display screen. display, to control the air conditioning functions such as the temperature or the intensity of the ventilation, the audio system as the volume.
Un des buts de l'invention est de proposer un bouton de commande multifonction amélioré par rapport à ceux de la technique, de structure simple, de faible encombrement et qui soit ergonomique.  One of the aims of the invention is to propose a multifunction control button improved over those of the technique, of simple structure, of small size and which is ergonomic.
A cet effet, la présente invention a pour objet un bouton de commande multifonction comportant un socle et un organe mobile pouvant être déplacé entre une position de repos et au moins une position active à l'encontre d'une butée correspondante du socle, caractérisé en ce qu'il comporte un capteur de force présentant au moins une surface sensible à une pression d'appui apte à délivrer une information représentative de l'intensité de la force d'appui exercée sur la surface sensible, fixé dans une butée du socle face à un ergot d'actionnement de l'organe mobile de sorte que l'ergot d'actionnement contacte la surface sensible du capteur de force en butée dans la position active.  To this end, the subject of the present invention is a multifunction control button comprising a base and a movable member that can be moved between a rest position and at least one active position against a corresponding abutment of the base, characterized in that it comprises a force sensor having at least one surface sensitive to a bearing pressure capable of delivering information representative of the intensity of the pressing force exerted on the sensitive surface, fixed in a stop of the base face an actuating pin of the movable member so that the actuating pin contacts the sensitive surface of the force sensor in abutment in the active position.
On conçoit alors que les joysticks comprenant une multitude d'interrupteurs peuvent être remplacés par un dispositif de commande multifonction comportant un capteur de force. Le capteur de force permet d'accéder à une information supplémentaire : l'intensité de la force exercée par l'utilisateur pour pousser l'organe mobile en butée, déduite de la sortie analogique du capteur de force. Cette information supplémentaire peut être utilisée pour paramétrer les commandes des organes du véhicule automobile. L'utilisateur peut ainsi doser l'intensité d'une fonction en dosant la force d'appui de l'organe mobile vers une butée, ce qui le rend ergonomique et facile d'emploi. En outre, le capteur de force est de structure simple, de faible encombrement et permet de simplifier la connectique électrique. It is then conceivable that the joysticks comprising a multitude of switches can be replaced by a multifunction control device comprising a force sensor. The force sensor provides access to additional information: the intensity of the force exerted by the user to push the movable member in abutment, deduced from the analog output of the force sensor. This additional information can be used to set the controls of the organs of the motor vehicle. The user can thus dose the intensity of a function by measuring the bearing force of the movable member towards a stop, which makes it ergonomic and easy to use. In addition, the force sensor is simple in structure, compact and simplifies the electrical connection.

The movable member 3 can be moved between a rest position and at least one active position against a corresponding stop of the base 2.
Par exemple et comme illustré sur la figure 1, l'organe mobile 3 peut être translaté par un utilisateur entre une position centrale de repos et au moins quatre positions actives dans quatre directions Ll, L2, L3, L4 coplanaires et perpendiculaires. Dans les positions actives, un ergot d'actionnement 5a, 5b, 5c, 5d de l'organe mobile 3 est translaté à l'encontre d'une butée 6a, 6b, 6c, 6d du socle 2 limitant la course en translation de l'organe mobile 3. Ainsi, l'organe mobile 3 présente quatre ergots d'actionnement 5a-5d angulairement espacés d'environ 90° et respectivement destinés à contacter une des quatre butées du socle 2 dans une des quatre positions actives. For example and as illustrated in Figure 1, the movable member 3 can be translated by a user between a central rest position and at least four active positions in four directions Ll, L2, L3, L4 coplanar and perpendicular. In the active positions, an actuating pin 5a, 5b, 5c, 5d of the movable member 3 is translated against an abutment 6a, 6b, 6c, 6d of the base 2 limiting the travel in translation of the organ mobile 3. Thus, the movable member 3 has four actuating lugs 5a-5d angularly spaced about 90 ° and respectively intended to contact one of the four stops of the base 2 in one of four active positions.
Les ergots d'actionnement 5a-5d comportent par exemple un matériau élastomère, tel qu'un matériau EPDM (éthylène-propylène-diène monomère).  The actuating lugs 5a-5d comprise, for example, an elastomeric material, such as an EPDM (ethylene-propylene-diene monomer) material.
Pour faciliter le guidage en translation, le socle 2 peut comporter des moyens de guidage en translation dans les quatre directions latérales Ll, L2, L3, L4 coopérant avec des moyens de guidage en translation complémentaires de l'organe mobile 3. Par exemple, le socle 2 comporte quatre rainures de guidage (dont on distingue un côté d'une rainure de guidage 7 sur la figure 1), parallèles aux directions latérales Ll, L2, L3, L4. L'organe mobile 3 comporte quatre nervures complémentaires 17a, 17b, 17c, 17d (figure 3), pouvant coulisser dans une rainure de guidage associée 7 du socle 2 lorsque l'organe mobile 3 est translaté.  To facilitate translation guidance, the base 2 may comprise means for guiding in translation in the four lateral directions L1, L2, L3, L4 cooperating with complementary translational guiding means of the movable member 3. For example, the base 2 has four guide grooves (one side of a guide groove 7 in Figure 1), parallel to the lateral directions L1, L2, L3, L4. The movable member 3 comprises four complementary ribs 17a, 17b, 17c, 17d (Figure 3), slidable in an associated guide groove 7 of the base 2 when the movable member 3 is translated.
Conformément au mode de réalisation de la figure 1, l'organe mobile 3 comporte une molette de préhension 3a et une embase 3b, la molette de préhension 3a étant montée rotative dans l'embase 3b, dans les deux sens de rotation autour de l'axe longitudinal I-I du bouton de commande 1, voir flèche R sur la figure 1. La molette de préhension 3a présente une partie supérieure préhensible surmontant une partie inférieure tabulaire 8 s'insérant dans un logement cylindrique correspondant de l'embase 3b, la partie supérieure préhensible faisant saillie de l'embase 3b. La partie inférieure tabulaire 8 peut ainsi tourner dans le logement cylindrique de l'embase 3b par manipulation de la partie supérieure préhensible. Le bouton de commande multifonction 1 comporte également un capteur angulaire, tel qu'un encodeur rotatif, (non représenté) pour mesurer et associer une commande à la variation angulaire exercée par l'utilisateur.  According to the embodiment of Figure 1, the movable member 3 comprises a gripping wheel 3a and a base 3b, the gripping wheel 3a being rotatably mounted in the base 3b, in both directions of rotation around the longitudinal axis II of the control button 1, see arrow R in Figure 1. The gripping wheel 3a has a gripping upper portion surmounting a tabular lower portion 8 inserted in a corresponding cylindrical housing of the base 3b, the upper part gripping protruding from the base 3b. The lower tabular portion 8 can thus rotate in the cylindrical housing of the base 3b by manipulation of the gripping upper part. The multifunction control knob 1 also comprises an angular sensor, such as a rotary encoder, (not shown) for measuring and associating a control with the angular variation exerted by the user.
En outre, la molette de préhension 3a peut être montée mobile axialement dans le logement cylindrique de l'embase 3b, dans une direction axiale I-I perpendiculaire au plan défini par les directions latérales de déplacement en translation Ll, L2, L3, L4 (flèche F sur la figure 1) de sorte que l'extrémité 18 de la partie inférieure tabulaire 8 actionne un commutateur 19 fixé dans le logement cylindrique de l'embase 3b en regard de l'extrémité 18. Le commutateur peut être couplé à un cloquant pour générer un retour haptique (non représenté). Le bouton de commande multifonction 1 peut également comporter un moyen de rappel de l'organe mobile 3 d'une position active en translation vers la position centrale de repos. Par exemple, une extrémité 9 de l'embase 3b de l'organe mobile 3 comporte un plongeur 10 élastiquement sollicité par un ressort de rappel 11 à l'encontre d'un creux correspondant 12 ménagé dans un fond du socle 2. Le plongeur 10 est élastiquement sollicité à l'encontre du creux 12 conformé pour rappeler l'organe mobile 3 en position centrale de repos lors du déplacement de celui-ci en translation vers une position active. In addition, the gripping wheel 3a can be mounted axially movable in the cylindrical housing of the base 3b, in an axial direction II perpendicular to the plane defined by the lateral directions of displacement in translation Ll, L2, L3, L4 (arrow F in Figure 1) so that the end 18 of the lower tabular portion 8 actuates a switch 19 fixed in the cylindrical housing of the base 3b opposite the end 18. The switch can be coupled to a blister to generate a haptic feedback (not shown). The multifunction control button 1 may also include means for returning the movable member 3 to a position that is active in translation towards the central rest position. For example, an end 9 of the base 3b of the movable member 3 comprises a plunger 10 resiliently biased by a return spring 11 against a corresponding recess 12 formed in a bottom of the base 2. The plunger 10 is elastically biased against the recess 12 shaped to return the movable member 3 in the central position of rest during displacement thereof in translation to an active position.
Le creux 12 présente par exemple une forme générale en croix à quatre branches (figure 3). Chaque branche est parallèle à une direction de translation Ll, L2, L3, L4 de l'organe mobile 3, chaque branche étant plus longue que la distance entre la position centrale de repos de l'organe mobile 3 et la butée correspondante 6a-6d. La profondeur maximale du creux 12 correspond à la position centrale de repos de l'organe mobile 3, la profondeur du creux rétrécissant vers les extrémités des branches. Ainsi, lorsque l'organe mobile 3 est déplacé en position active, le plongeur 10 se déplace dans la branche correspondante du creux 12. Puis, lorsque l'utilisateur relâche l'organe mobile 3, le ressort de rappel 10 pousse l'extrémité 9 à l'endroit le plus profond de la croix, rappelant l'organe mobile 3 en position centrale de repos.  The recess 12 has for example a general cross shape with four branches (Figure 3). Each branch is parallel to a translation direction L1, L2, L3, L4 of the movable member 3, each branch being longer than the distance between the central rest position of the movable member 3 and the corresponding stop 6a-6d . The maximum depth of the recess 12 corresponds to the central rest position of the movable member 3, the depth of the recess narrowing towards the ends of the branches. Thus, when the movable member 3 is moved into the active position, the plunger 10 moves in the corresponding branch of the recess 12. Then, when the user releases the movable member 3, the return spring 10 pushes the end 9 at the deepest point of the cross, reminding the movable member 3 in central rest position.
Le capteur de force 4 présente au moins une surface sensible à une pression d'appui apte à délivrer une information représentative de l'intensité de la force d'appui exercée sur la surface sensible, fixée dans une butée du socle 2, face à un ergot d'actionnement 5a-5d de l'organe mobile 3. Conformément à l'exemple des figures 1 à 4, le capteur de force 4 comporte ainsi quatre surfaces sensibles 4a, 4b, 4c, 4d disposées respectivement dans les quatre butées 6a-6d du socle 2, face aux quatre ergots d'actionnement respectifs 5a-5d de l'organe mobile. Ainsi, pour chacune des quatre positions actives pouvant être prise par l'organe mobile 3, l'ergot d'actionnement 5a-5d contacte une surface sensible associée 4a- 4d du capteur de force 4, interposé entre l'organe mobile 3 et la butée 6a-6d.  The force sensor 4 has at least one surface sensitive to a bearing pressure capable of delivering information representative of the intensity of the pressing force exerted on the sensitive surface, fixed in a stop of the base 2, facing a 5a-5d actuating pin of the movable member 3. In accordance with the example of Figures 1 to 4, the force sensor 4 thus comprises four sensitive surfaces 4a, 4b, 4c, 4d disposed respectively in the four stops 6a-4d. 6d of the base 2, facing the four respective actuating lugs 5a-5d of the movable member. Thus, for each of the four active positions that can be taken by the movable member 3, the actuating pin 5a-5d contacts an associated sensitive surface 4a-4d of the force sensor 4, interposed between the movable member 3 and the stop 6a-6d.
Plus précisément, le socle 2 comporte un logement annulaire cylindrique au niveau des butées 6a-6d pour loger le capteur de force 4. Le capteur de force 4 est monté sur le chant, de façon cylindrique dans le logement, de manière à cercler au moins partiellement la périphérie de l'embase 3b de l'organe mobile 3. Le logement annulaire cylindrique peut également comporter des pattes de retenue pour maintenir les bordures du capteur de force 4. More specifically, the base 2 comprises a cylindrical annular housing at the abutments 6a-6d for housing the force sensor 4. The force sensor 4 is mounted on the edge, cylindrically in the housing, so as to ring at least partially the periphery of the base 3b of the movable member 3. The cylindrical annular housing can also have retaining tabs to hold the edges of the force sensor 4.
Les surfaces sensibles du capteur de force 4 utilisent des résistances sensibles à la pression (également connu sous le nom capteur FSR pour « Force Sensing Resistor ») permettant de détecter un appui simple d'un utilisateur et, en fonction de l'intensité de l'appui exercé sur la surface sensible, de déclencher un type particulier de commande. En exerçant une pression sur la couche FSR, sa résistance ohmique (diminue permettant ainsi, par application d'une tension électrique adaptée, de mesurer la pression appliquée et / ou la localisation de l'endroit où la pression est exercée. Ces capteurs de force 4 présentent l'avantage d'être minces et souples. Ils permettent que le dispositif de commande soit compact et que l'organe mobile puisse actionner une commande avec une faible course d'actionnement.  The sensitive surfaces of the force sensor 4 use pressure-sensitive resistors (also known as the FSR sensor for "Force Sensing Resistor") to detect a simple user's support and, depending on the intensity of the sensor. pressing on the sensitive surface, to trigger a particular type of command. By exerting a pressure on the FSR layer, its ohmic resistance (decreases thus making it possible, by application of a suitable electrical voltage, to measure the applied pressure and / or the location of the place where the pressure is exerted. 4 have the advantage of being thin and flexible, they allow the control device to be compact and the movable member to actuate a control with a small actuating stroke.
Les surfaces sensibles 4a-4d du capteur de force 4 se rejoignent sur une nappe de fils 13 destinée à être connectée à une unité de traitement comme par exemple visible à la figure 5.  The sensitive surfaces 4a-4d of the force sensor 4 meet on a sheet of son 13 intended to be connected to a processing unit as for example visible in FIG. 5.
La technologie employée pour les surfaces sensibles du capteur de force est par exemple celle décrite dans le document US 4, 810, 992 ou FR 2683649 ou US 5, 008, 497. Les surfaces sensibles du capteur de force comportent une couche isolante muni sur un premier côté d'une première couche conductrice et d'une deuxième couche conductrice sur le côté opposé. Selon un premier exemple, au moins une des deux couches conductrices est une couche de semi-conducteur sensible à une variation de pression. Une variation de contact entre les couches entraîne une modification de la résistance à travers la couche semi-conductrice. Selon un deuxième exemple, au lieu d'appliquer une couche conductrice contre la couche FSR, on peut utiliser une pellicule résistive portant un réseau conducteur déposé sur la pellicule sous forme de deux peignes d'électrodes en disposition interdigitale. Cette pellicule est alors scellée à la couche FSR de manière que les peignes d'électrodes affleurent la couche semi-conductrice FSR. Si aucune force n'est appliquée à une telle structure, la résistance entre les bornes des peignes d'électrodes est très élevée. Par contre, lorsque le FSR est soumis à une force, la couche FSR shunte les électrodes et la résistance diminue proportionnellement à l'intensité de la force. Selon un troisième exemple, le capteur de force comporte une couche FSR prise en sandwich entre une couche résistive et une couche conductrice. The technology used for the sensitive surfaces of the force sensor is, for example, that described in document US Pat. No. 4,810,992 or US Pat. No. 2,628,649 or US Pat. No. 5,008,497. The sensitive surfaces of the force sensor comprise an insulating layer provided on a first side of a first conductive layer and a second conductive layer on the opposite side. According to a first example, at least one of the two conductive layers is a semiconductor layer that is sensitive to a variation of pressure. A change in contact between the layers causes a change in the resistance across the semiconductor layer. In a second example, instead of applying a conductive layer against the FSR layer, it is possible to use a resistive film carrying a conductive network deposited on the film in the form of two interdigital interdigital electrode combs. This film is then sealed to the FSR layer so that the electrode combs are flush with the FSR semiconductor layer. If no force is applied to such a structure, the resistance between the terminals of the electrode combs is very high. On the other hand, when the FSR is subjected to a force, the FSR layer shunts the electrodes and the resistance decreases proportionally to the intensity of the force. In a third example, the force sensor comprises an FSR layer sandwiched between a resistive layer and a conductive layer.
Selon un autre exemple de technologie, les surfaces sensibles du capteur de force sont celles décrites par exemple dans les documents EP 1 429 356 ou EP 1 429 355. Le capteur de force comporte deux feuilles souples de support espacées l'une de l'autre par des entretoises dans lesquelles des trous définissant des zones actives (les surfaces sensibles) du capteur de force sont ménagées. Dans ces zones actives, les feuilles souples de support portent sur des faces mutuellement en regard des éléments sensibles à une variation de pression, telle qu'une encre résistive imprimée, comme du carbone, permettant de réaliser un contact électrique lors de la compression du capteur. Les entretoises, par exemple élastiques, comportent une colle ou un adhésif à double face.  According to another example of technology, the sensitive surfaces of the force sensor are those described for example in documents EP 1 429 356 or EP 1 429 355. The force sensor comprises two flexible support sheets spaced from one another by spacers in which holes defining active areas (the sensitive surfaces) of the force sensor are provided. In these active zones, the flexible support sheets bear on mutually opposite faces elements sensitive to a variation of pressure, such as a printed resistive ink, such as carbon, making it possible to make an electrical contact during the compression of the sensor. . The spacers, for example elastic, comprise a glue or a double-sided adhesive.
Le bouton de commande multifonction 1 est par exemple monté dans un dispositif de commande pour véhicule automobile comportant en outre une unité de traitement configurée pour modifier une commande en fonction de l'intensité de la pression de l'appui qui est exercé sur le capteur de force 4 par l'organe mobile 3 du bouton de commande multifonction.  The multifunction control button 1 is for example mounted in a control device for a motor vehicle further comprising a processing unit configured to modify a control as a function of the intensity of the pressure of the support which is exerted on the sensor. force 4 by the movable member 3 of the multifunction control knob.
Selon un exemple d'utilisation représenté en figure 6, le dispositif de commande 14 comporte en outre un écran 16 et l'unité de traitement 15 est configurée pour modifier l'affichage de l'écran 16 en fonction de l'intensité et de la direction de la pression de l'appui qui est exercé sur le capteur de force 4 par l'organe mobile 3. Par exemple, l'unité de traitement 15 est configurée pour adapter le zoom de l'image affichée sur l'écran 16 en fonction de l'intensité de la pression exercée par un utilisateur sur l'organe mobile 3. Selon un autre exemple, l'unité de traitement 15 est configurée pour adapter la vitesse de déplacement de l'image affichée sur l'écran 16 dans la direction sélectionnée en fonction de l'intensité de la pression exercée par l'organe mobile 3.  According to an example of use shown in FIG. 6, the control device 14 further comprises a screen 16 and the processing unit 15 is configured to modify the display of the screen 16 as a function of the intensity and the direction of the pressure of the support which is exerted on the force sensor 4 by the movable member 3. For example, the processing unit 15 is configured to adapt the zoom of the image displayed on the screen 16 by according to the intensity of the pressure exerted by a user on the movable member 3. According to another example, the processing unit 15 is configured to adapt the speed of movement of the image displayed on the screen 16 in the direction selected according to the intensity of the pressure exerted by the movable member 3.
Le déplacement axial de l'organe mobile 3 peut par exemple faire office d'interrupteur de validation de la sélection d'une fonction et/ ou de la mise en marche ou arrêt du dispositif de commande 14, la rotation de l'organe mobile 3 permet par exemple le déplacement dans des menus de l'écran pour sélectionner une fonction, le déplacement en translation vers les directions Ll et L2 permet par exemple de déplacer l'image de l'écran 16 à droite ou à gauche et le déplacement en translation vers les directions L3, L4, permet d'enclencher l'agrandissement ou le rétrécissement de l'image. En outre, la vitesse de déplacement (ou défilement) de l'image affichée sur l'écran 16 dans la direction sélectionnée (à droite ou à gauche par exemple) et/ou la vitesse d'agrandissement ou de rétrécissement de l'image, varie avec l'intensité de la force exercée par l'utilisateur à l'encontre de la butée correspondante. Le dispositif de commande peut alors être utilisé pour la commande d'un système de navigation, l'image affichée correspondant à une carte de navigation. L'utilisateur peut alors visualiser directement l'impact de son actionnement de l'organe mobile 3. Il peut donc doser l'intensité de la force d'appui qu'il exerce sur celui- ci en fonction du résultat visualisé sur l'image affichée sur l'écran. The axial displacement of the movable member 3 may for example act as a switch for enabling the selection of a function and / or for starting or stopping the control device 14, the rotation of the movable member 3 allows for example the displacement in menus of the screen to select a function, the translational movement to the directions L1 and L2 allows for example to move the image of the screen 16 to the right or left and the displacement in translation towards directions L3, L4, allows to start enlarging or narrowing the image. In addition, the speed of movement (or scrolling) of the image displayed on the screen 16 in the selected direction (right or left for example) and / or the speed of enlargement or narrowing of the image, varies with the intensity of the force exerted by the user against the corresponding stop. The control device can then be used to control a navigation system, the displayed image corresponding to a navigation map. The user can then directly visualize the impact of his actuation of the movable member 3. He can therefore measure the intensity of the support force that he exerts on the latter as a function of the result visualized on the image. displayed on the screen.
On conçoit alors que les joysticks comprenant une multitude d'interrupteurs peuvent être remplacés par un bouton de commande multifonction 1 comportant un capteur de force 4. Le capteur de force 4 permet d'accéder à une information supplémentaire : l'intensité de la force exercée par l'utilisateur pour pousser l'organe mobile 3 en butée, déduite de la sortie analogique du capteur de force 4. Cette information supplémentaire peut être utilisée pour paramétrer les commandes des organes du véhicule automobile. L'utilisateur peut ainsi doser l'intensité d'une fonction en dosant la force d'appui de l'organe mobile 3 vers une butée, ce qui rend le bouton de commande multifonction plus ergonomique et facile d'emploi. En outre, le capteur de force 4 est de structure simple, de faible encombrement et permet de simplifier la connectique électrique.  It is then conceivable that the joysticks comprising a multitude of switches can be replaced by a multifunction control button 1 comprising a force sensor 4. The force sensor 4 provides access to additional information: the intensity of the force exerted by the user to push the movable member 3 in abutment, deduced from the analog output of the force sensor 4. This additional information can be used to parameterize the controls of the bodies of the motor vehicle. The user can thus measure the intensity of a function by measuring the bearing force of the movable member 3 towards a stop, which makes the multifunction control knob more ergonomic and easy to use. In addition, the force sensor 4 is simple in structure, compact and simplifies the electrical connection.
