Description

COMBINE D'INSTRUMENTS NUMERIQUE POUR PLANCHE DE BORD DE VEHICULE AUTOMOBILE A SURFACE D'AFFICHAGE MODULABLE.  DIGITAL INSTRUMENT COMBINATION FOR A MOTOR VEHICLE DASHBOARD WITH A MODULAR DISPLAY SURFACE.
Domaine de l'invention Field of the invention
La présente invention concerne les combinés d'instruments numériques pour planche de bord de véhicule automobile.  The present invention relates to digital instrument combinations for dashboard of a motor vehicle.
Arrière-plan de l'invention Background of the invention
Classiquement composés d'une pluralité de cadrans analogiques à aiguilles associés à des voyants lumineux, les combinés d'instruments sont utilisés pour fournir au conducteur une multitude de données relatives au fonctionnement d'un véhicule automobile, telles que par exemple, les vitesses instantanée et moyenne, le régime moteur, le nombre de kilomètres parcourus depuis l'origine ou sur un laps de temps déterminé, le niveau de carburant, ou bien encore la consommation moyenne. Ils permettent également d'afficher des signaux d'alerte (température moteur excessive, niveau d'huile insuffisant, portière non ou mal fermée, ceinture de sécurité non bouclée, etc.) et des témoins signalant l'activation de certains dispositifs du véhicule (clignotants, frein à main, feux de position, de croisement ou de route).  Conventionally composed of a plurality of analog dials with hands associated with indicator lights, the instrument handsets are used to provide the driver with a multitude of data relating to the operation of a motor vehicle, such as, for example, instantaneous speeds and average, the engine speed, the number of kilometers traveled from the origin or over a certain period of time, the fuel level, or even the average fuel consumption. They also make it possible to display warning signals (excessive engine temperature, insufficient oil level, door not properly closed, seat belt not fastened, etc.) and warning lights indicating the activation of certain devices of the vehicle ( turn signals, handbrake, position, passing or road lights).
Ces combinés d'instruments, intégrés à la planche de bord du véhicule, sont habituellement disposés derrière le volant de conduite dans l'axe de vision directe du conducteur, de sorte que ce dernier puisse consulter les informations affichées sans avoir à détourner son regard de la route.  These instrument combinations, integrated into the dashboard of the vehicle, are usually arranged behind the steering wheel in the direct line of vision of the driver, so that the latter can see the information displayed without having to look away from the road.
Ces dernières années ont vu l'apparition de combinés d'instruments entièrement numériques comportant un écran d'affichage LCD à matrice active (LCD-TFT) en lieu et place des cadrans analogiques à aiguilles.  In recent years there have been the appearance of fully digital instrument handsets with an active matrix LCD display (LCD-TFT) in place of analogue needle dials.
Ces combinés d'un nouveau type qui offrent une très bonne qualité d'image en termes de résolution, de contraste et de luminosité, sont en outre configurables par le conducteur du véhicule qui peut ainsi choisir au moins en partie les modules qu'il souhaite voir s'afficher sur l'écran ainsi que le style d'affichage (cadrans à aiguilles similaires aux cadrans analogiques ou bien affichage sous la forme de graduations ou de chiffres traduisant la valeur de la grandeur concernée) et l'ambiance du combiné (sobre avec fond d'éclairage de couleur sombre, ou sportif avec fond d'éclairage de couleur vive). These new type of handsets, which offer a very good image quality in terms of resolution, contrast and brightness, are also configurable by the driver of the vehicle which can thus choose at least in part the modules he wants see display on the screen as well as the display style (dials with needles similar to analog dials or display in the form of graduations or figures reflecting the value of the quantity concerned) and the ambience of the handset (sober with dark, or sporty lighting background with bright color lighting background).
Ces combinés numériques permettent également de piloter un certain nombre de fonctions du véhicule (climatisation, système audio, verrouillage centralisé, éclairage, etc.) via des commandes situées sur le volant ou déportées au niveau de la console centrale du véhicule.  These digital handsets can also control a number of vehicle functions (air conditioning, audio system, central locking, lighting, etc.) via controls located on the steering wheel or remote at the center console of the vehicle.
Toutefois, de par leur surface limitée, ces combinés d'instruments numériques ne sont pas adaptés à l'affichage de la cartographie routière détaillée du système d'assistance à la navigation du véhicule.  However, due to their limited surface area, these digital instrument handsets are not suitable for displaying the detailed road map of the vehicle navigation assistance system.
Cette carte est donc généralement affichée sur un écran déporté au niveau de la console centrale du véhicule, ce qui contraint le conducteur du véhicule à déplacer son regard latéralement et à quitter momentanément les yeux de la route.  This card is usually displayed on a remote screen at the center console of the vehicle, which forces the driver of the vehicle to move his eyes laterally and momentarily leave the eyes of the road.
Objet et résumé de l'invention Object and summary of the invention
La présente invention vise donc à palier à cet inconvénient.  The present invention therefore aims to overcome this disadvantage.
Elle propose à cet effet un combiné d'instruments pour planche de bord de véhicule automobile comportant des moyens de visualisation numériques situés derrière le volant et aptes à afficher à l'intention du conducteur une multitude de données relatives à la conduite dudit véhicule ;  It proposes for this purpose a combined instruments for a motor vehicle dashboard comprising digital display means located behind the steering wheel and able to display for the driver a multitude of data relating to the driving of said vehicle;
caractérisé en ce que lesdits moyens de visualisation comportent deux écrans d'affichage numériques mobiles latéralement et un écran d'affichage numérique fixe,  characterized in that said display means comprises two laterally movable digital display screens and a fixed digital display screen,
ledit combiné d'instruments étant apte à adopter une première configuration compacte dans laquelle les deux dits écrans mobiles sont accolés l'un à l'autre par l'un de leurs bords latéraux de sorte à dissimuler ledit écran fixe situé derrière, et une seconde configuration étendue dans laquelle lesdits écrans mobiles sont écartés latéralement l'un de l'autre de sorte à rendre visible ledit écran fixe pour ledit conducteur. said instrument cluster being adapted to adopt a first compact configuration in which said two movable screens are contiguous to each other by one of their lateral edges so as to conceal said fixed screen located behind, and a second extended configuration in which said movable screens are laterally spaced apart from each other so as to make said fixed screen visible to said driver.
Le combiné d'instruments selon l'invention permet ainsi d'offrir une surface d'affichage modulable en fonction des données que le conducteur souhaite visualiser.  The instrument cluster according to the invention thus makes it possible to offer a display surface which can be modulated according to the data that the driver wishes to display.
La configuration compacte dans laquelle seuls les deux écrans mobiles accolés sont visibles, sera ainsi particulièrement adaptée à l'affichage d'informations relatives au fonctionnement du véhicule automobile et que l'on retrouve usuellement sur les combinés d'instruments numériques actuels, telles que par exemple les vitesses instantanée et moyenne, le régime moteur, le nombre de kilomètres parcourus, l'autonomie restante, la consommation moyenne, la température de consigne du système de climatisation, le nom de la station de radio ou du morceau en cours d'écoute, ainsi que d'éventuels signaux ou témoins d'alertes.  The compact configuration in which only two contiguous mobile screens are visible, will thus be particularly suitable for displaying information relating to the operation of the motor vehicle and that is usually found on the current digital instrument handsets, such as by example, the instantaneous and average speeds, the engine speed, the number of kilometers traveled, the remaining battery life, the average consumption, the cooling system set point temperature, the name of the radio station or track being listened to as well as any warning signals or warning lights.
La configuration étendue, dans laquelle le troisième écran fixe devient visible, offre une surface d'affichage complémentaire permettant si besoin de visualiser la cartographie routière du système d'aide à la navigation du véhicule. Le combiné d'instruments selon l'invention permet ainsi d'améliorer l'ergonomie de conduite et de réduire les risques d'accidents en évitant au conducteur de détourner son regard de l'axe de la route.  The extended configuration, in which the third fixed screen becomes visible, provides a complementary display surface allowing if necessary to view the road map of the navigation system of the vehicle. The combination of instruments according to the invention thus improves the ergonomics of driving and reduce the risk of accidents by avoiding the driver to look away from the axis of the road.
D'autre part et du fait que l'ensemble des informations nécessaires au conducteur peuvent être affichées sur ce combiné, ce dernier permet de se passer de l'écran au niveau de la console centrale du véhicule.  On the other hand and the fact that all the necessary information to the driver can be displayed on the handset, the latter makes it possible to dispense with the screen at the center console of the vehicle.

Description détaillée de plusieurs modes de réalisation Detailed description of several embodiments
La zone conducteur de la planche de bord 1 représentée sur les figures comprend dans sa partie supérieure un renfoncement 2 supportant un combiné d'instruments 10 selon l'invention, centré sur le plan vertical médian du volant 3 de sorte à faire face au regard du conducteur du véhicule.  The conductive zone of the dashboard 1 shown in the figures comprises in its upper part a recess 2 supporting a combined instrument 10 according to the invention, centered on the median vertical plane of the steering wheel 3 so as to face the view of the driver of the vehicle.
Comme cela est bien visible sur les figures 2 et 4, le combiné d'instruments 10 comporte deux écrans de visualisation mobiles 30, 40 ainsi qu'un écran de visualisation fixe 20 disposé derrière ces deux écrans mobiles 30, 40 (cet écran fixe 20 se trouvant ainsi légèrement plus éloigné du regard conducteur du véhicule que les deux autres 30, 40)  As can be seen in FIGS. 2 and 4, the instrument cluster 10 comprises two mobile display screens 30, 40 as well as a fixed display screen 20 disposed behind these two mobile screens 30, 40 (this fixed screen 20 thus being slightly further away from the driver's view of the vehicle than the other two 30, 40)
Ces trois écrans sont de préférence basés sur la technologie d'affichage à cristaux liquides LCD (« Light Crystal Display » en anglais) et à matrice active TFT (« Thin film transistor » en anglais), ce type d'écran ayant pour avantages d'offrir une très bonne qualité d'image en termes de résolution, de contraste et de luminosité. These three screens are preferably based on LCD ("Light Crystal Display") and TFT ("Thin film transistor") active matrix technology. this type of screen having the advantages of offering a very good image quality in terms of resolution, contrast and brightness.
L'écran de visualisation fixe 20 qui présente ici une forme sensiblement carrée, est centré par rapport au plan vertical médian du volant 3 de sorte à se trouver positionné parfaitement dans l'axe de vision du conducteur du véhicule (figures 1 à 4).  The fixed display screen 20 which here has a substantially square shape, is centered relative to the median vertical plane of the steering wheel 3 so as to be positioned perfectly in the line of vision of the driver of the vehicle (Figures 1 to 4).
Comme illustré par la figure 5, cet écran 20 est en outre relié rigidement à la planche bord 1 par l'intermédiaire d'une patte de fixation 21.  As illustrated in FIG. 5, this screen 20 is also rigidly connected to the board 1 by means of a fastening lug 21.
De forme rectangulaire, les deux écrans mobiles 30, 40, sont identiques et présentent des dimensions supérieures à celles de l'écran central 20, notamment en termes de longueur et de hauteur.  Rectangular, the two movable screens 30, 40 are identical and have dimensions greater than those of the central screen 20, in particular in terms of length and height.
Comme illustré sur les figures 2, 4 et 5, chaque écran mobile 30, 40, est porté par un bras 31, 41 présentant un profil en forme de J orienté horizontalement.  As illustrated in Figures 2, 4 and 5, each movable screen 30, 40, is carried by an arm 31, 41 having a J-shaped profile oriented horizontally.
Plus précisément, chaque bras support 31, 41 comprend une branche principale 41A, une seconde branche de plus petite longueur en T 41B, ainsi qu'une base 41C reliant ces deux branches entre elles et s'étendant perpendiculairement à ces dernières (figure 5).  More specifically, each support arm 31, 41 comprises a main branch 41A, a second branch of shorter length T 41B, and a base 41C connecting these two branches together and extending perpendicular thereto (Figure 5) .
L'extrémité de la branche principale 41A opposée à la base 41C est reliée rigidement à la partie supérieure de la face arrière de l'écran mobile correspondant 30, 40 surplombant l'écran fixe 20, de sorte à éviter que cette branche principale 41A du bras support ne puisse interférer avec cet écran fixe 20 lors du déplacement latéral de l'écran mobile.  The end of the main branch 41A opposite the base 41C is rigidly connected to the upper part of the rear face of the corresponding movable screen 30, 40 overhanging the fixed screen 20, so as to prevent this main branch 41A of the support arm can not interfere with this fixed screen 20 during the lateral displacement of the mobile screen.
La seconde branche en T 41B est quant à elle montée à coulissement dans une glissière respective courbe 32, 42 à section en T ménagée à l'intérieur de la planche de bord 1. Comme illustré sur les figures 2 et 4, ces glissières 32, 42, sont symétriques par rapport au plan vertical médian du volant 3 et présentent une concavité orientée vers le volant 3.  The second T-branch 41B is slidably mounted in a respective curved slideway 32, 42 with a T-section formed inside the dashboard 1. As illustrated in FIGS. 2 and 4, these slideways 32, 42, are symmetrical with respect to the median vertical plane of the steering wheel 3 and have a concavity oriented towards the steering wheel 3.
De préférence, les bras support 31, 41 sont creux de sorte à pouvoir loger les faisceaux électriques reliant ces écrans 30, 40 à une source d'alimentation continue telle que la batterie et/ou au boîtier de servitude intelligent (BSI) gérant l'affichage. Preferably, the support arms 31, 41 are hollow so as to accommodate the electrical bundles connecting these screens 30, 40 to a a continuous power source such as the battery and / or intelligent service enclosure (BSI) managing the display.
Le combiné d'instruments 10 selon l'invention comporte également des moyens pour entraîner à coulissement les bras support 31, 41 des écrans 30, 40 le long des glissières courbes 32, 42.  The instrument cluster 10 according to the invention also comprises means for slidably driving the support arms 31, 41 of the screens 30, 40 along the curved rails 32, 42.
Ces derniers non représentés sur les figures mais bien connus en soi, comportent par exemple pour chaque écran 30, 40, une crémaillère s'étendant à l'intérieur et le long de la glissière correspondante 32, 42 et coopérant avec un pignon denté monté rotatif sur la seconde branche en T 41B du bras support 31, 41, l'entraînement à rotation de ce pignon entraînant le coulissement du bras 31, 41 et de l'écran 30, 40 le long de la glissière 32, 42.  The latter not shown in the figures but well known per se, comprise for example for each screen 30, 40, a rack extending inside and along the corresponding slideway 32, 42 and cooperating with a rotatably mounted toothed pinion on the second T-branch 41B of the support arm 31, 41, the rotation drive of this pinion causing the sliding of the arm 31, 41 and the screen 30, 40 along the slide 32, 42.
Les moyens d'entraînement à coulissement sont actionnés via des moteurs électriques dissimulés à l'intérieur de la planche de bord 1 et pilotés par le boîtier de servitude intelligent du véhicule, de sorte que les écrans mobiles 30, 40 se déplacent latéralement de manière symétrique par rapport au plan vertical médian du volant 3.  The sliding drive means are actuated via concealed electric motors within the dashboard 1 and driven by the intelligent service housing of the vehicle, so that the movable screens 30, 40 move laterally symmetrically. relative to the median vertical plane of the steering wheel 3.
Ce déplacement des écrans mobiles permet ainsi au combiné d'instruments 1 selon l'invention de pouvoir adopter deux configurations offrant des surfaces d'affichage différentes.  This displacement of the moving screens thus allows the instrument cluster 1 according to the invention to be able to adopt two configurations offering different display surfaces.
Dans une première configuration dite compacte et illustrée par les figures 1 et 2, les deux écrans mobiles 30, 40 qui s'étendent alors dans un même plan transversal à l'axe du véhicule, sont accolés l'un à l'autre par deux de leurs bords latéraux et suivant le plan vertical médian du volant 3, de sorte à dissimuler l'écran fixe 20 situé juste derrière.  In a first so-called compact configuration and illustrated in FIGS. 1 and 2, the two movable screens 30, 40 which then extend in the same plane transverse to the axis of the vehicle, are joined to each other by two their lateral edges and along the vertical vertical plane of the steering wheel 3, so as to hide the fixed screen 20 located just behind.
Dans la seconde configuration dite étendue et illustrée par les figures 3 et 4, les deux écrans mobiles 30, 40 sont écartés latéralement l'un de l'autre de sorte à rendre visible l'écran fixe 20 pour le conducteur du véhicule, ces derniers étant en outre disposés légèrement en V de sorte à donner un aspect courbé à l'affichage.  In the second so-called extended configuration illustrated in FIGS. 3 and 4, the two movable screens 30, 40 are laterally spaced from each other so as to make visible the fixed screen 20 for the driver of the vehicle, the latter being further arranged slightly V-shaped so as to give a curved appearance to the display.
Avantageusement dans cette configuration, l'écartement entre les deux écrans mobiles 30, 40 correspond sensiblement à la largeur de l'écran fixe 20 afin d'offrir une certaine continuité visuelle au conducteur. Advantageously in this configuration, the spacing between the two movable screens 30, 40 substantially corresponds to the width of the fixed screen 20 to provide some visual continuity to the driver.
On va maintenant décrire un mode de fonctionnement préféré du combiné d'instruments 1 selon l'invention.  We will now describe a preferred mode of operation of the instrument cluster 1 according to the invention.
A l'arrêt et en position parking du véhicule, le combiné d'instruments 10 adopte sa configuration compacte et les trois écrans 20, 30 et 40 sont éteints.  When stopped and in the parking position of the vehicle, the instrument cluster 10 adopts its compact configuration and the three screens 20, 30 and 40 are off.
Dès que la position « + Après contact » (+APC) ou l'une des positions suivantes du Neiman est enclenchée (ce qui signifie que la clé de contact est verrouillée dans le Neiman), les deux écrans mobiles 30, 40 s'allument et affichent un certain nombre d'informations usuelles relatives au fonctionnement du véhicule automobile, telles que par exemple : les vitesses instantanée et moyenne, le régime moteur, le nombre de kilomètres parcourus, l'autonomie restante, la consommation moyenne, la température de consigne du système de climatisation, le nom de la station de radio ou du morceau en cours d'écoute, ainsi que d'éventuels signaux ou témoins d'alertes (figure 1).  As soon as the position "+ After contact" (+ APC) or one of the following positions of the Neiman is engaged (which means that the ignition key is locked in the Neiman), the two movable screens 30, 40 light up and display a certain number of usual information relating to the operation of the motor vehicle, such as for example: the instantaneous and average speeds, the engine speed, the number of kilometers traveled, the remaining range, the average consumption, the set temperature the air conditioning system, the name of the radio station or track being listened to, as well as any warning signals or warning lights (Figure 1).
Bien entendu, le type d'informations affichées sur les écrans mobiles, leur agencement, l'ambiance de fond ainsi que le style d'affichage de ces informations (cadrans à aiguilles similaires aux cadrans analogiques ou bien affichage de type numérique avec des chiffres traduisant la valeur de la grandeur concernée) peuvent varier, ces éléments n'important pas directement à l'invention.  Of course, the type of information displayed on the mobile screens, their layout, the background and the display style of this information (dials with needles similar to analog dials or digital type display with numbers translating the value of the quantity concerned) may vary, these elements not being of direct relevance to the invention.
Lorsque le conducteur du véhicule lance, via par exemple une molette de commande située au niveau de la console centrale du véhicule, le système d'aide à la navigation par satellite, l'écran fixe 20 s'allume et les écrans mobiles 30, 40 se déplacent latéralement et symétriquement de sorte à ce que le combiné d'instruments 1 vienne occuper sa configuration étendue. L'écran fixe 20, désormais visible, affiche alors la cartographie routière environnante tel qu'illustré sur la figure 3. Cet écran 20 est également susceptible d'afficher les messages visuels indiquant le chemin à prendre pour rejoindre une destination donnée choisie par ce conducteur. Ces messages visuels nécessitant une surface d'affichage somme toute limitée, peuvent également en variante, apparaître sur l'un ou l'autre des écrans mobiles 30, 40. When the driver of the vehicle launches, via for example a control wheel located at the center console of the vehicle, the satellite navigation aid system, the fixed screen 20 lights and the movable screens 30, 40 move laterally and symmetrically so that the instrument cluster 1 comes to occupy its extended configuration. The fixed screen 20, now visible, then displays the surrounding road map as shown in Figure 3. This screen 20 is also likely to display visual messages indicating the path to take to reach a given destination chosen by this driver . These visual messages requiring a limited display surface, can alternatively, appear on one or the other of the movable screens 30, 40.
L'arrêt du système d'aide à la navigation ou le passage en position parking du véhicule entraîne automatiquement l'extinction de l'écran fixe 20 et le retour du combiné d'instrument 10 à sa configuration compacte. Le passage en position parking entraine également l'extinction des deux écrans mobiles 30, 40.  Stopping the navigation aid system or switching to the parking position of the vehicle automatically switches off the fixed screen 20 and the return of the instrument cluster 10 to its compact configuration. The transition to the parking position also causes the extinction of the two movable screens 30, 40.
Selon des variantes de réalisation non représentés du combiné d'instruments selon l'invention, la forme et/ou les dimensions des écrans d'affichage fixe et mobiles sont différents.  According to non-illustrated embodiments of the instrument cluster according to the invention, the shape and / or the dimensions of the fixed and mobile display screens are different.
Selon d'autres variantes de réalisation non représentées, le profil des glissières et rectiligne et/ou les écrans mobiles sont montés pivotants sur les bras supports.  According to other embodiments not shown, the profile rails and rectilinear and / or movable screens are pivotally mounted on the support arms.
Selon encore d'autres variantes de réalisation non représentées :  According to still other embodiments not shown:
- l'écran fixe est de type transparent de sorte que le conducteur puisse visualiser la route au travers de celui-ci ;  - The fixed screen is transparent type so that the driver can view the route through it;
- les moyens pour entraîner à coulissement les écrans mobiles le long des glissières sont différents ;  the means for slidably driving the movable screens along the slideways are different;
- le mécanisme d'articulation des écrans mobiles est également différent et/ou celui-ci est entièrement dissimulé sous la planche de bord du véhicule ;  - The articulation mechanism of the movable screens is also different and / or it is completely hidden under the dashboard of the vehicle;
- les écrans fixe et mobiles sont recouverts d'un filtre polarisant anti-reflets ; et/ou  - The fixed and mobile screens are covered with a polarizing anti-reflective filter; and or
- le combiné d'instruments comprend une visière pare-soleil surplombant les écrans fixe et mobiles.  - the instrument cluster includes a sun visor overhanging the fixed and mobile screens.
Bien entendu, la présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais elle englobe l'ensemble des variantes d'exécution à la portée de l'homme du métier.  Of course, the present invention is not limited to the embodiments described and shown, but encompasses all the alternative embodiments within the reach of the skilled person.
