Description

"Agencement d'affichage d'informations à l'intérieur d'un habitacle de véhicule automobile" "Information display arrangement inside a passenger compartment of a motor vehicle"
L'invention concerne un agencement d'affichage d'informations pour le conducteur et/ou les passagers à l'intérieur d'un habitacle de véhicule automobile.The invention relates to an information display arrangement for the driver and / or the passengers inside a passenger compartment of a motor vehicle.
L'invention concerne plus particulièrement un agencement d'affichage d'informations pour le conducteur et/ou les passagers à l'intérieur d'un habitacle de véhicule automobile qui comporte au moins un pare-brise, agencé en avant du conducteur, et une planche de bord dont une partie supérieure est agencée à proximité d'une zone inférieure du pare-brise, du type qui comporte au moins une zone d'affichage, agencée à proximité de la partie supérieure de la planche de bord, qui est destinée à présenter au conducteur et/ou aux passagers des informations représentatives du fonctionnement du véhicule et/ou de ses équipements.The invention more particularly relates to an information display arrangement for the driver and / or the passengers inside a passenger compartment of a motor vehicle which comprises at least one windshield, arranged in front of the driver, and a instrument panel, an upper part of which is arranged near a lower zone of the windscreen, of the type which includes at least one display zone, arranged near the upper part of the dashboard, which is intended for present to the driver and / or passengers information representative of the operation of the vehicle and / or its equipment.
On connaît de nombreux exemples d'agencements d'affichage de ce type.Numerous examples of display arrangements of this type are known.
Les informations à l'usage du conducteur ont longtemps été présentées par un bloc d'instruments qui était logé dans la planche de bord, derrière le volant au droit d'un regard du conducteur.The information for the use of the driver has long been presented by a block of instruments that was housed in the dashboard behind the steering wheel at the right of a driver's eye.
Cette conception ancienne s'est vu supplanter ces dernières années par des agencements dans lesquels les informations sont présentées par un afficheur qui est disposé de manière déportée dans une partie centrale supérieure de la planche de bord.This old design has been supplanted in recent years by arrangements in which the information is presented by a display which is disposed remotely in an upper central portion of the dashboard.
Cette conception présente de nombreux avantages.This design has many advantages.
En premier lieu, les informations sont accessibles au conducteur ainsi qu'à ses passagers.First, the information is accessible to the driver and his passengers.
En second lieu, l'afficheur étant plus éloigné des yeux du conducteur que le traditionnel bloc d'instruments, cette conception permet en partie de s'affranchir des inévitables difficultés d'accommodation qu'éprouvait le conducteur quand son regard passait de la vision de la route à celle du bloc d'instruments, beaucoup plus proche, logé derrière le volant.Secondly, the display being further away from the driver's eyes than the traditional instrument block, this design makes it possible in part to overcome the inevitable the driver's difficulties of accommodation when his eyes passed from the vision of the road to that of the instrument block, much closer, lodged behind the wheel.
Toutefois, un tel afficheur présente l'inconvénient de proposer une vision qui est fortement tributaire de la luminosité ambiante, de sorte que les informations ne sont pas toujours lisibles.However, such a display has the disadvantage of providing a vision that is highly dependent on the ambient brightness, so that the information is not always readable.
De plus, la taille limitée d'un tel afficheur permet de ne présenter simultanément qu'un nombre limité d'informations, ce qui oblige le conducteur et/ou les passagers du véhicule à sélectionner les informations qu'ils désirent voir affichées.In addition, the limited size of such a display makes it possible to simultaneously present only a limited number of information, which forces the driver and / or passengers of the vehicle to select the information they wish to display.
Enfin, un tel afficheur n'allège que très peu la planche de bord en terme de style.Finally, such a display does not alleviate very little dashboard in terms of style.
Plus récemment, on a imaginé des agencements baptisés "à visée tête haute", qui permettent la projection des informations par transparence directement sur le pare-brise du véhicule.More recently, designs have been designed called "head-up", which allow the projection of information by transparency directly on the windshield of the vehicle.
Cette conception est nécessairement liée à une présentation limitée d'informations, et elle présente de surcroît l'inconvénient d'une lisibilité limitée, la route défilant par transparence derrière les informations projetées.This design is necessarily linked to a limited presentation of information, and it also has the disadvantage of limited readability, the road scrolling by transparency behind the projected information.
L'invention remédie à ces inconvénients en proposant une nouvelle conception d'un agencement du type précédemment décrit dans lequel les informations sont projetées sur une large surface opaque dans une zone éloignée au maximum du conducteur.The invention overcomes these drawbacks by proposing a new design of an arrangement of the type described above in which the information is projected onto a large opaque surface in a zone at most away from the conductor.

Dans la description qui va suivre, des chiffres de référence identiques désignent des pièces identiques ou ayant des fonctions similaires.In the following description, like reference numerals designate like parts or having similar functions.
On a représenté sur les figures un agencement 10 d'affichage d'informations pour le conducteur 12 et/ou les passagers à l'intérieur d'un habitacle 14 de véhicule automobile. L'habitacle 14 comporte au moins un pare-brise 16, agencé en avant d'une place 18 du conducteur 12, et une planche de bord 20 dont une partie supérieure 22 est agencée à proximité d'une zone inférieure 24 du pare-brise 16.There is shown in the figures an information display arrangement 10 for the driver 12 and / or the passengers inside a passenger compartment 14 of a motor vehicle. The passenger compartment 14 comprises at least one windshield 16, arranged in front of a seat 18 of the driver 12, and a dashboard 20, an upper portion 22 of which is arranged near a lower zone 24 of the windshield. 16.
De manière connue, un tel agencement 10 comporte au moins une zone d'affichage 26, agencée à proximité de la partie supérieure de la planche 20 de bord, qui est destinée à présenter au conducteur et/ou aux passagers des informations représentatives du fonctionnement du véhicule et/ou de ses équipements. Conventionnellement, comme l'illustre la figure 1, un tel agencement 10 comporte un afficheur constituant la zone d'affichage 26, et cet afficheur est disposé de manière déportée dans une partie centrale supérieure de la planche de bord. Cette conception présente l'inconvénient de proposer une vision qui est fortement tributaire de la luminosité ambiante, de sorte que les informations ne sont pas toujours lisibles.In known manner, such an arrangement 10 comprises at least one display zone 26, arranged near the upper part of the dashboard, which is intended to present to the driver and / or passengers information representative of the operation of the vehicle. vehicle and / or equipment. Conventionally, as illustrated in Figure 1, such an arrangement 10 comprises a display constituting the display area 26, and this display is disposed remotely in an upper central portion of the dashboard. This design has the disadvantage of providing a vision that is highly dependent on the ambient brightness, so that the information is not always readable.
De plus, la taille limitée d'un tel afficheur 26 permet de ne présenter simultanément qu'un nombre limité d'informations, ce qui oblige le conducteur et/ou les passagers du véhicule à sélectionner les informations qu'ils désirent voir affichées.In addition, the limited size of such a display 26 makes it possible to simultaneously present only a limited number of information, which forces the driver and / or passengers of the vehicle to select the information they wish to see displayed.
La sélection de ces informations est par exemple effectuée par l'intermédiaire de commandes du véhicule, et cette conception pose d'évidents problèmes de sécurité car la manipulation de ces commandes, lorsqu'elle est effectuée alors que le véhicule roule, peut distraire le conducteur de sa conduite et être ainsi une source d'accidents.The selection of this information is for example carried out via vehicle controls, and this design poses obvious safety problems because the handling of these controls, when done while the vehicle is running, can distract the driver. of his conduct and thus be a source of accidents.
Pour remédier à cet inconvénient, propose une nouvelle conception d'un agencement du type précédemment décrit dans lequel les informations sont projetées sur une large surface opaque dans une zone éloignée au maximum du conducteur.To remedy this drawback, proposes a new design of an arrangement of the type described above in which the information is projected onto a large opaque surface in a zone at most away from the conductor.
Dans ce but, comme l'illustrent les figures 2 et 3, l'invention propose un agencement 1 0 du type décrit précédemment, caractérisé en ce qu'il comporte un dispositif 28 de projection des informations qui est destiné à projeter les informations sur un revêtement opaque recouvrant au moins en partie la zone inférieure 24 du pare-brise 16.For this purpose, as illustrated in FIGS. 2 and 3, the invention proposes an arrangement 10 of the type described above, characterized in that it comprises a device 28 for projecting information which is intended to project information on a opaque coating covering at least part of the lower zone 24 of the windshield 16.
Plus particulièrement, le dispositif 28 de projection comporte :More particularly, the projection device 28 comprises:
- un bandeau 30 de revêtement opaque, qui s'étend transversalement sur au moins une partie de la zone inférieure 24 du pare-brise 1 6,a strip 30 of opaque coating, which extends transversely over at least a portion of the lower zone 24 of the windshield 1 6,
- un élément 32 de projection, qui est porté par la partie 22 supérieure de la planche 20 de bord, et qui est destiné à projeter les informations sur le bandeau 30,a projection element 32, which is carried by the upper part 22 of the board, and which is intended to project the information on the strip 30,
- une unité 34 de centrale de contrôle de l'élément 32 de projection, qui est susceptible de commander l'affichage des informations représentatives du fonctionnement du véhicule et/ou de ses équipements.a control unit 34 of the projection element 32, which is capable of controlling the display of the information representative of the operation of the vehicle and / or its equipment.
L'unité 34 centrale de contrôle est avantageusement susceptible de transmettre des signaux, par exemple par l'intermédiaire d'une liaison filaire 36, à l'élément 32 de projection, pour déterminer l'affichage des informations et la manière dont celles-ci sont affichées. De la sorte, il est possible de conférer aux informations projetées toutes les formes de présentation souhaitées, et aussi de définir le style de leur affichage, à la différence d'un afficheur conventionnel dont le style est figé une fois pour toutes lors de la conception du véhicule. L'agencement 10 selon l'invention est donc évolutif et il permet de modifier l'apparence des informations projetées.The central control unit 34 is advantageously capable of transmitting signals, for example via a wire link 36, to the projection element 32, in order to determine the display of the information and the manner in which the information is displayed. are displayed. In this way, it is possible to give the projected information all the desired forms of presentation, and also to define the style of their display, unlike a conventional display whose style is frozen once and for all during the design of the vehicle. The arrangement 10 according to the invention is therefore evolutionary and it makes it possible to modify the appearance of the projected information.
Il est par exemple possible d'envisager un système de gestion logicielle de l'unité 34 centrale de contrôle, qui permette à l'utilisateur de choisir entre plusieurs habillages différents des informations, aussi appelés "skins". I l est aussi possible d'envisager une lise à jour ou un téléchargement de nouveaux habillages ou "skins" à partir de l'unité centrale. I I conviendra de noter que la liaison fi laire 36 n'est pas li mitative de l'invention, et qu'elle pourrait aussi être remplacée par une liaison optique ou radio.For example, it is possible to envisage a software management system of the central control unit, which enables the user to choose between several different skins of the information, also called "skins". It is also possible to consider updating or downloading new skins or "skins" from the central unit. It should be noted that the wire bond 36 is not limiting of the invention, and could also be replaced by an optical or radio link.
Dans le mode de réalisation préféré de l'i nvention, l'élément 32 de protection est logé dans la planche de bord, par exemple dans un logement 38 agencé dans la partie supérieure 22 de la planche de bord. Cette configuration permet une dissimulation complète dudit élément d'affichage 32.In the preferred embodiment of the invention, the protection element 32 is housed in the dashboard, for example in a housing 38 arranged in the upper part 22 of the dashboard. This configuration allows complete concealment of said display element 32.
Avantageusement, l'élément 32 de projection comporte des moyens (non représentés) de réglage de la netteté de l'image à projeter. Le même élément 32 de projection peut donc être utilisé pour des véhicules de types différents, entre lesquels la distance entre l'élément 32 de projection et le bandeau 30 est variable. Selon une autre caractéristique essentielle de l'invention, l'élément 32 de projection comporte des moyens (non représentés) de variation de la luminosité des informations projetées.

Selon une autre caractéristique de l'invention, l'agencement 10 comporte des moyens (non représentés) de détection de la position de l'œil 40 d'un conducteur du véhicule, qui sont susceptibles d'émettre une information représentative de cette position à l'intention de l'unité 34 centrale de contrôle de l'élément de projection pour commander l'élément 32 de projection en adéquation avec la position de l'œil 40 du conducteur 12. Plusieurs modes de réalisation peuvent être envisagés pour la mise en œuvre de l'élément 32 de projection.According to another characteristic of the invention, the arrangement 10 comprises means (not shown) for detecting the position of the eye 40 of a driver of the vehicle, which are capable of transmitting information representative of this position to the intention of the central control unit of the projection element to control the projection element 32 in accordance with the position of the eye 40 of the conductor 12. Several embodiments may be envisaged for the implementation the projection element 32.
Selon un premier mode de réalisation préféré de l'invention, l'élément 32 de projection comporte au moins un projecteur (non représenté) à diodes laser projetant les informations sur un miroir motorisé (non représenté) qui est susceptible de réfléchir les informations sur la bandeau 30 suivant des positions variables. En particulier, le miroir motorisé permet un ajustement en hauteur des informations projetées.According to a first preferred embodiment of the invention, the projection element 32 comprises at least one projector (not shown) with laser diodes projecting the information on a motorized mirror (not shown) which is capable of reflecting the information on the band 30 according to variable positions. In particular, the motorized mirror allows a height adjustment of the projected information.
Selon un second mode de réalisation de l'invention, l'élément de projection 32 comporte au moins un projecteur vidéo. Ce projecteur vidéo peut être un projecteur à tube cathodiques, ou notamment un projecteur vidéo à dalle plasma ou encore à cristaux liquides. Une caractéristique essentielle de l'invention est qu'elle permet d'obtenir une planche de bord 20 sensiblement allégée en terme de style par rapport à une planche de bord classique.According to a second embodiment of the invention, the projection element 32 comprises at least one video projector. This video projector can be a cathode ray tube projector, or in particular a video projector with plasma panel or liquid crystal. An essential feature of the invention is that it provides a dashboard 20 substantially lighter in terms of style compared to a classic dashboard.
A cet effet, comme l'illustre la figure 3, la partie supérieure 22 de la planche de bord 20 recouvre la partie inférieure 24 du pare-brise 16 et qu'elle comporte une fenêtre 42 débouchant sur la partie inférieure 24 du pare-brise 16 comportant le bandeau 30 de revêtement opaque.For this purpose, as shown in Figure 3, the upper portion 22 of the dashboard 20 covers the lower portion 24 of the windshield 16 and has a window 42 opening on the lower portion 24 of the windshield 16 having the strip 30 of opaque coating.
De préférence, la fenêtre 42 est agencée dans le prolongement d'un capot 44 du véhicule et à ce titre, elle ne diminue en rien le champ de vision du conducteur.Preferably, the window 42 is arranged in the extension of a hood 44 of the vehicle and as such, it does not diminish the field of vision of the driver.
L'invention propose donc un agencement innovant d'affichage d'informations pour le conducteur et/ou les passagers à l'intérieur d'un habitacle de véhicule automobile, offrant une grande lisibilité sur une grande surface d'affichage. The invention therefore provides an innovative information display arrangement for the driver and / or passengers inside a passenger compartment of a motor vehicle, offering great readability on a large display surface.
