Description

DISPOSITIF DE VISUALISATION D'INFORMATIONS PAR PRO.1ECTION VIEW INFORMATION DEVICE BY PRO.1ECTION
L'invention se rapporte au domaine technique de l'affichage et de la visualisation des informations de conduite dans un véhicule automobile .Elle concerne un dispositif, dit de visualisation-tête haute (Head Up Display ou HUD) ,ou de visualisation tête moyenne (HMD). The invention relates to the technical field of display and visualization of the driving information in a motor vehicle .It relates to a device, said high viewing head (Head Up Display, or HUD), or viewing medium head ( HMD).

L'augmentation de la quantité d'informations à fournir au conducteur et l'aspect d'urgence de certaines d'entre elles favorisent l'introduction dans l'automobile de systèmes de visualisation-tête haute ,ou tête moyenne ,mis en oeuvre depuis plusieurs années dans l'industrie aéronautique. Increasing the amount of information to provide the driver and emergency appearance of some of them favor the introduction in the automotive head-up-display systems, or average head implemented since several years in the aviation industry.

Ce type de développement est illustré notamment par la publication EP 0416222, ayant pour objet un dispositif d'affichage pour véhicule. This type of development is illustrated in particular by the publication EP 0416222, relating to a display device for vehicle. Ce dispositif est constitué essentiellement d'un afficheur , de miroirs de réflexion ,d'un ensemble optique de restitution ,et d'un mélangeur intégré au pare-brise du véhicule. This device consists essentially of a display, reflection mirrors, an optical reproduction unit, and an integrated mixer to the vehicle windshield.

L'expérience montre que l'exploitation d'un dispositif de ce type est entravée par ,l'extrême variabilité de l'éclairement ambiant ,inhérent au déplacement du véhicule. Experience shows that the operation of a device of this type is hampered by the extreme variability of the ambient illumination, the inherent movement of the vehicle. Ce problème est incontournable dans l'exploitation des systèmes HUD ou HMD This problem is unavoidable in the use of HUD or HMD systems

En effet le paysage vu à travers le mélangeur ,et superposé par celuici aux informations de conduite ,présente des niveaux de brillance lumineuse très variables. Indeed the landscape seen through the mixer, and overlaid by the latter to the driving information, has very light variable gloss levels. Ces variations affectent considérablement les performances d'un tel système. These changes significantly affect the performance of such a system. Elles sont à l'origine de nombreux problèmes de restitution dont notamment: They are the source of many rendering issues including:
- la diminution du contraste dans les conditions de fort - decreasing the contrast in conditions of strong
éclairement (journées ensoleillées ,neige ,...), lighting (sunny days, snow, ...)
- la perception parasite, par reflet sur le mélangeur, d'éléments - stray perception, by reflection on the mixer elements
constitutifs du dispositif ,tels que le cadre de l'afficheur ou de constituent of the device, such that part of the display or
la planche de bord : cette perception parasite intervient the dashboard: this parasite perception intervenes
principalement dans des conditions de faible éclairement. primarily in low light conditions.

Le premier problème mentionné ci-dessus peut être solutionné ,dans certains cas ,par un dispositif électronique permettant d'ajuster la brillance de l'afficheur : cette technique est applicable pour des afficheurs du type VFD (Vaccum Fluorescent Display). The first problem mentioned above can be solved, in some cases, by an electronic device for adjusting the brightness of the display: This technique is applicable for displays of the VFD type (Vaccum Fluorescent Display). Par contre, il est moins aisé de faire varier la brillance et le constraste d'un afficheur du type LCD (Liquid Cristal Display). By cons, it is less easy to vary the brightness and contrast of the LCD type display (Liquid Crystal Display). Quant au second problème mentionné, on ne connait pas à ce jour de solution satisfaisante. The second problem mentioned, we do not know to this day a satisfactory solution.

La présente invention se propose de remédier d'une façon simple et automatique aux deux problèmes qui viennent d'être évoqués, sans impliquer de contraintes particulières relatives à la technologie de l'afficheur The present invention proposes to overcome in a simple and automatic way to the two problems just mentioned, without implying any particular constraints on the display technology
Elle concerne un dispositif de visualisation d'informations par projection comportant un afficheur d'informations dont l'image est transmise par l'intermédiaire d'un ensemble optique de restitution à un mélangeur situé au dessus de la planche de bord du véhicule, de façon à superposer cette image au paysage perçu par le conducteur du véhicule au travers du pare-brise et de ce mélangeur . It relates to a projection information display device comprising a display information including the image is transmitted via an optical reproduction unit to a mixer located above the vehicle dashboard, so to superimpose this image with the landscape seen by the driver of the vehicle through the windshield and the mixer. Ce dispositif est caractérisé en ce que le mélangeur est un mélangeur à transmission variable, tel que dans des conditions d'éclairement fort sa transmission diminue de façon à augmenter le constraste de cette image par rapport au paysage, tandis que dans des conditions d'éclairement faible sa transmission augmente, de façon à diminuer la perception des réflexions parasites This device is characterized in that the mixer is a variable mixer transmission, such as in strong light conditions decreases its transmission so as to increase the contrast of the image with respect to the landscape, while in lighting conditions low transmission increases, so as to decrease the perception of interfering reflections

Sur la figure 1 ,on a représenté schématiquement le conducteur In Figure 1, there is shown schematically the driver
I d'un véhicule automobile 2, assis à son poste de conduite 3. Ce conducteur 1 observe le paysage au travers du pare-brise 4. Un afficheur 5 intégré à la planche de bord 10 délivre des informations de conduite dont l'image 9, transmise par l'intermédiaire de l'ensemble optique de restitution 7, se réfléchit sur le mélangeur 8 intégré au pare-brise 4. Le conducteur 1 aperçoit donc une image virtuelle 9 des informations de conduite de l'afficheur ,située à l'extérieur du véhicule 1, en avant du pare-brise 4. Cette image 9, est superposée au paysage, grâce au mélangeur 8. I of a motor vehicle 2, seated in his driving position 3. This driver 1 observes the scenery through the windshield 4. An integrated display 5 to the dashboard 10 delivers driving information including image 9 transmitted through the optical reproduction unit 7, is reflected on the integrated mixer 8 to the windshield 4. the conductor 1 thus perceives a virtual image of the display 9 of the driving information, located in the outside the vehicle 1 in front of the windshield 4. This image 9, is superimposed on the landscape, thanks to the mixer 8.

Conformément à l'invention, le mélangeur 8, qu'il soit de type passif ou actif, peut également être disposé sur le dessus de la planche de bord 10. Ce mode de réalisation particulier de l'invention est illustré par la figure 2 .Sur celle-ci, on remarque que l'afficheur 5 est placé au niveau du plafond 17 du véhicule 2. Cette disposition s'avère particulièrement avantageuse, mais ne présente aucun caractère d'obligation. According to the invention, the mixer 8, whether passive or active type, may also be disposed on top of the dashboard 10. This particular embodiment of the invention is illustrated by Figure 2. on it, we notice that the display 5 is placed at the ceiling 17 of the vehicle 2. This arrangement is particularly advantageous, but has no obligation character.

Conformément à l'invention ,le mélangeur 8 mis en oeuvre dans ces dispositifs ,est un mélangeur à transmission variable. According to the invention, the mixer 8 used in these devices is a variable transmission mixer. Ainsi, dans des conditions d'éclairement important, la transmission de la lame diminue, permettant une augmentation du contraste, tandis que dans des conditions de faible éclairement, la transmission du mélangeur augmente ,de façon à diminuer la perception des reflets parasites. Thus, in important lighting conditions, the blade of the transmission decreases, allowing an increase in contrast, while in low light conditions, the transmission of the mixer increases, so as to decrease the perception of stray reflections.

L'invention prévoit I'utilisation de mélangeurs de type passif ou de type actif Dans le cas de la figure 2, le facteur de transmission des mélangeurs utilisés devrait pouvoir varier normalement entre 30% et 80%. The invention provides I'utilisation of passive type or active type mixers In the case of Figure 2, the mixers transmittance should be used normally vary between 30% and 80%. Les mélangeurs passifs seront constitués de matériaux photochromes, dont les caractéristiques de transmission se modifient automatiquement en fonction de la lumière ambiante. The passive mixers will consist of photochromic materials, the transmission characteristics will change automatically depending on the ambient light. Les matériaux photochromes utilisables sont par exemple le produit commercialisé sous la référence "PGE" par la Société "CORNING", d'épaisseur 2 mm, qui posséde les caractèristiques citées dessus. Suitable photochromic materials are for example the product sold under the reference "PGE" the Company "Corning", 2 mm thick, which has the special features mentioned above. Les mélangeurs actifs les mieux adaptés à la mise en oeuvre de l'invention sont les cellules à cristaux liquides ou les cellules électrochromes. The most suitable active mixers in the implementation of the invention are liquid crystal cells or electrochromic cells. La commande de ces cellules est illustrée par la figure 3, sur laquelle on a fait apparaître, outre la cellule 8, ellemême, un photodétecteur 11 de lumière ambiante 12, agissant sur le comportement optique de celle-ci, par l'intermédiaire d'un organe de commande 13. Control of these cells is shown in Figure 3, on which there can be seen, in addition to the cell 8, itself, a photodetector 11 of ambient light 12, acting on the optical behavior thereof by means of a control member 13.

Les figures 4A, 4B, SA et 5B illustrent l'intégration du mélangeur 8 sur la planche de bord 10. Sur les figures 4A et 4B, le mélangeur 8 pivote sur celle-ci autour de l'axe d'articulation 14. Ce pivotement permet à la fois de régler l'orientation du mélangeur 8 de façon à obtenir une visualisation optimale des informations affichées, par le conducteur 1, et de rabattre complètement le mélangeur 8 sur la planche de bord 10, lorsque l'utilisation du dispositif n'est plus souhaitée. Figures 4A, 4B, SA and 5B illustrate the integration of the mixer 8 of the instrument panel 10. In Figs 4A and 4B, the mixer 8 rotates thereon around the hinge pin 14. This pivoting allows both to adjust the orientation of the mixer 8 so as to obtain an optimal display of the information displayed by the conductor 1, and to fold completely the mixer 8 of the dashboard 10 when using the device n ' is desired.

L'invention prévoit également l'adaptation d'un cache 15, destiné à supprimer les reflets parasites sur le mélangeur 8 notamment lorsqu'il est rabattu sur la planche de bord 10. Selon l'exemple de réalisation des figures 4A et 4b B ,le cache 15 pivote sur la planche de bord 10 autour du même axe 14 d'articulation que le mélangeur 8, de façon à pouvoir se plaquer contre celui-ci dans toutes les positions. The invention also provides for the adaptation of a cover 15 for suppressing the parasitic reflections on the mixer 8 in particular when it is folded on the instrument panel 10. According to the embodiment of Figures 4A and 4B B, the cover 15 is pivoted on the instrument panel 10 about the same axis 14 of articulation that the mixer 8, so as to be pressed against the latter in any position. Selon l'exemple de réalisation des figures SA et 5B, le cache 15 ou 15' coulisse parallèlement à la planche de bord de façon à venir recouvrir le mélangeur 8 lorsque celui-ci est rabattu contre la planche de bord 10. Dans tous les cas ,les déplacements du mélangeur 8 et du cache 15' pourront avantageusement être pris en charge par un moteur électrique 16, 16', le conducteur disposant alors à son poste de conduite d'organes de commande correspondants, non représentés sur ces figures. According to the embodiment of Figs SA and 5B, the cache 15 or 15 'parallel to the slide next way dashboard cover the mixer 8 when the latter is folded against the instrument panel 10. In all cases , the movements of the mixer 8 and the cache 15 'can advantageously be supported by an electric motor 16, 16', then with the driver in his driving position corresponding control members, not shown in these figures. Pour des raisons d'uniformité et d'esthétique le cache 15, 15', peut avantageusement être fabriqué dans le même matériau que la planche de bord 10. For consistency and aesthetic reasons the cache 15, 15 'may advantageously be made of the same material as the dashboard 10.

L'invention permet donc de résoudre le problème de la variabilité de l'éclairement ambiant, en intervenant non pas au niveau de la technologie de l'afficheur 5, mais au niveau du mélangeur 8. Parmi les nombreux avantages liés à la solution proposée, on peut citer notamment: The invention thus solves the problem of variability of ambient light, in not intervening in the technology of the display 5, but at the mixer 8. Among the many benefits of the proposed solution, there may be mentioned:
- l'adaptation automatique du dispositif aux conditions - the automatic adaptation of the device to the conditions
d'éclairement ambiant (jour, nuit, temps nuageux ou ambient lighting (day, night, cloudy or
ensoleillé...), - l'application de la solution proposée à tous les types d'afficheur - l'atténuation des reflets parasites, -1' absence de commande électronique de réglage, dans le cas de l'utilisation d'un mélangeur passif. sunny ...), - the application of the proposed solution to all types of display - the attenuation of unwanted reflections, -1 absence of electronic control adjustment, in the case of using a mixer passive.
