Description
Dispositif d'affichage pour un véhicule automobile et véhicule comportant un tel dispositif Display device for a motor vehicle and vehicle comprising such a device
La présente invention concerne un dispositif d'affichage pour un véhicule automobile, ainsi qu'un véhicule automobile comportant un tel dispositif.The present invention relates to a display device for a motor vehicle, and a motor vehicle comprising such a device.
Dans le cadre de l'amélioration de la sécurité routière, une partie non négligeable de mesures relève de la construction des véhicules automobiles. Un certain nombre de mesures parmi celles-ci concerne l'interface entre un utilisateur du véhicule automobile, notamment, mais non exclusivement, le conducteur du véhicule, et les différents organes d'un véhicule automobile. Un de ces interfaces est l'affichage de données ou d'informations, par exemple la vitesse du véhicule ou la distance parcourue, affichés jusqu'à récemment par des instruments traditionnels à cadran et aiguille en ce qui concerne la vitesse et par un compteur mécanique en ce qui concerne la distance parcourue.As part of the improvement of road safety, a significant part of the measures concern the construction of motor vehicles. A number of measures among these concerns the interface between a user of the motor vehicle, including, but not limited to, the driver of the vehicle, and the various components of a motor vehicle. One of these interfaces is the display of data or information, for example the speed of the vehicle or the distance traveled, displayed until recently by traditional instruments dial and needle with respect to speed and a mechanical counter as regards the distance traveled.
La lecture de ces instruments traditionnels n'étant pas toujours facile, notamment la nuit et encore moins en pleine journée contre le soleil, des instruments à affichage purement numérique à grands chiffres et sur un écran rétro-éclairé ont été développés. Malgré l'amélioration générale de la lecture que de tels instruments ont apportés, il n'en reste pas moins que le conducteur ou tout autre utilisateur du véhicule doit regarder expressément vers les affichages qui apparaissent sur des instruments situés dans la planche de bord et doit donc quitter des yeux, même très brièvement, le champ de vision de la route ou de l'espace devant le véhicule automobile.Reading these traditional instruments is not always easy, especially at night and even less in the middle of the day against the sun, digital display instruments with large numbers and a backlit display have been developed. Despite the general improvement in reading that such instruments have brought, the fact remains that the driver or any other user of the vehicle must look specifically at the displays that appear on instruments in the dashboard and must so leave the eyes, even very briefly, the field of vision of the road or space in front of the motor vehicle.
Notons à cet endroit que la présente invention concerne principalement un dispositif pour afficher des informations destinées au conducteur du véhicule automobile. Toutefois, le dispositif de l'invention peut également être conformé de manière que tout autre utilisateur du véhicule automobile accompagnant le conducteur du véhicule automobile puisse lire ces informations sous les mêmes conditions que celles valables pour le conducteur. De même, un dispositif
individuel répondant aux mêmes critères peut être mis à la disposition de l'utilisateur accompagnant le conducteur du véhicule automobile pour faire apparaître soit les mêmes informations que pour le conducteur, soit des informations spécifiques. Aussi, pour simplifier le langage de la suite de la description de la présente invention, référence sera faite uniquement au conducteur du véhicule automobile.Note here that the present invention mainly relates to a device for displaying information for the driver of the motor vehicle. However, the device of the invention may also be shaped so that any other user of the motor vehicle accompanying the driver of the motor vehicle can read this information under the same conditions as those valid for the driver. Similarly, a device an individual meeting the same criteria may be made available to the user accompanying the driver of the motor vehicle to display either the same information as for the driver, or specific information. Also, to simplify the language of the following description of the present invention, reference will be made only to the driver of the motor vehicle.
Par ailleurs, des indications d'agencement telles que "devant", "derrière", "en haut", "en bas" et autres font référence à des positions telles qu'elles se présentent au conducteur du véhicule automobile.Furthermore, design indications such as "in front", "behind", "up", "down" and others refer to positions such as they appear to the driver of the motor vehicle.
Pour remédier aux inconvénients énoncés plus haut, et notamment pour réduire, voire éviter le risque inhérent à toute déviation du regard du conducteur, la technique automobile a repris un type d'afficheur utilisé depuis quelque temps déjà dans l'aviation, savoir un afficheur connu sous le nom afficheur à vision tête haute . Les afficheurs du type à vision tête haute sont destinés à projeter une information dans le champ de vision de l'espace devant le véhicule automobile afin que le conducteur du véhicule automobile puisse lire cette information sans quitter des yeux l'espace devant le véhicule automobile. Un autre avantage de ce type d'afficheur est que l'information peut être lue sans modification de l'accommodation des yeux du conducteur du véhicule .To overcome the drawbacks mentioned above, and in particular to reduce or even avoid the risk inherent in any deflection of the eyes of the driver, the automotive technology has taken a type of display used for some time already in aviation, namely a known display under the name head-up display. Head-up type displays are designed to project information into the field of view of the space in front of the motor vehicle so that the driver of the motor vehicle can read this information without taking his eyes off the space in front of the motor vehicle. Another advantage of this type of display is that the information can be read without changing the accommodation of the eyes of the driver of the vehicle.
Les dispositifs d'affichage de type tête haute sont parfois complétés par un dispositif d'affichage de type tête moyenne qui projette une information complémentaire au bord inférieur du champ de vision de l'espace devant le véhicule automobile ou juste en dessous de ce champ de vision. Ces dispositifs d'affichage complémentaires demandent une légère réorientation de la ligne de vue du conducteur du véhicule par rapport à la ligne de vue pour le champ de vision de l'espace devant le véhicule automobile, mais ne requièrent cependant pas
d'accommodation des yeux du conducteur du véhicule automobile .The head-up display devices are sometimes supplemented by a medium-head type display device which projects complementary information to the lower edge of the field of view of the space in front of the motor vehicle or just below this field of view. vision. These complementary display devices require a slight reorientation of the line of sight of the driver of the vehicle relative to the line of sight for the field of view of the space in front of the motor vehicle, but do not however require of accommodation of the eyes of the driver of the motor vehicle.
Pour obtenir la projection de l'information dans le champ de vision de l'espace devant le véhicule automobile, certains dispositifs d'affichage utilisent le pare-brise ou tout autre vitre appropriée comme lame réfléchissante. Un tel dispositif semble a priori avantageux, notamment en ce qui concerne le nombre de composantes nécessaires. Toutefois, l'inclinaison du pare-brise ou de toute autre vitre dans un véhicule automobile répond à des critères aérodynamiques ou de stabilité/résistance mécanique du véhicule automobile et ne présente ainsi pas systématiquement un angle d'inclinaison avantageux pour le positionnement de l'affichage dans le champ de vision du conducteur du véhicule automobile. De plus, le pare-brise ou tout autre vitre du véhicule automobile utilisé pour l'affichage présente une position fixe et ne peut donc pas être adapté à la taille du conducteur du véhicule automobile. Le but de l'invention est de remédier aux inconvénients énoncés ci avant.To obtain the projection of the information in the field of view of the space in front of the motor vehicle, certain display devices use the windshield or any other appropriate glass as a reflective plate. Such a device seems a priori advantageous, particularly with regard to the number of components required. However, the inclination of the windshield or any other window in a motor vehicle meets aerodynamic criteria or stability / mechanical strength of the motor vehicle and thus does not systematically have an advantageous angle of inclination for the positioning of the vehicle. display in the field of vision of the driver of the motor vehicle. In addition, the windshield or other window of the motor vehicle used for display has a fixed position and can not be adapted to the size of the driver of the motor vehicle. The object of the invention is to overcome the disadvantages mentioned above.
Avantageusement, le but de l'invention doit être atteint en utilisant une lame indépendante, de préférence à inclinaison variable. Le but de l'invention est atteint avec un dispositif d'affichage pour un véhicule automobile, comprenant une source lumineuse destinée à engendrer une information à afficher et une lame réfléchissant l'information vers un conducteur du véhicule. Selon l'invention, la lame est disposée de façon que la source lumineuse fasse apparaître l'information comme une image virtuelle en deux parties), une partie supérieure de l'image apparaissant juste au-dessus d'une limite inférieure d'un champ de vision sur l'espace devant le véhicule et une partie inférieure de l'image apparaissant juste en dessous de la limite inférieure du champ de vision sur l'espace devant le véhicule.
Grâce aux dispositions de l'invention, il n'est plus nécessaire d'afficher certaines informations sécuritaires, dont par exemple la vitesse, de façon redondante à un autre endroit de la planche de bord car les informations essentielles apparaissent dans le champ de vision alors que les informations moins importantes sont affichées juste en dessous de ce champ de vision. Par ailleurs, en faisant apparaître les informations importantes dans une zone proche du bord inférieur du champ de vision, ces informations n'apparaissent pas par superposition du fond de l'espace devant le véhicule automobile et évitent ainsi des problèmes de lecture suite à un fond très clair ou brillant (par exemple une route humide) . En outre, une forte déperdition éventuelle de lumière qui pourrait être occasionnée par réflexion sur la lame additionnée à une luminosité forte d'une route claire ou brillante impose d'avoir une source lumineuse extrêmement forte, souvent avec une luminosité supérieure à 10 000 Cd/m2) . La présente invention concerne également les caractéristiques ci-après considérées isolément ou selon toute combinaison techniquement possible :Advantageously, the object of the invention must be achieved by using an independent blade, preferably with variable inclination. The object of the invention is achieved with a display device for a motor vehicle, comprising a light source for generating information to display and a blade reflecting the information to a driver of the vehicle. According to the invention, the blade is arranged so that the light source causes the information to appear as a virtual image in two parts), an upper part of the image appearing just above a lower limit of a field of vision on the space in front of the vehicle and a lower part of the image appearing just below the lower limit of the field of view on the space in front of the vehicle. Thanks to the provisions of the invention, it is no longer necessary to display certain security information, including for example the speed, redundantly to another place on the dashboard because the essential information appear in the field of vision then that less important information is displayed just below this field of view. Moreover, by displaying the important information in an area near the lower edge of the field of view, this information does not appear by superimposing the bottom of the space in front of the motor vehicle and thus avoid reading problems following a background very clear or bright (eg a wet road). In addition, a strong loss of light that could be caused by reflection on the blade added to a bright light of a bright or bright road requires to have an extremely strong light source, often with a brightness greater than 10,000 Cd / m2).

La limite 14 correspond à une ligne droite partant des yeux 40 d'un conducteur du véhicule automobile et passant par le point le plus haut de la silhouette du capot du véhicule automobile qui se présente au conducteur du véhicule.
Ainsi, le dispositif de l'invention se situe derrière un volant 30 du véhicule automobile et émet une image virtuelle 6, 1 par réflexion de la source lumineuse 3, 4, par exemple un écran fortement lumineux, un tube de projection ou un objet éclairé, sur la lame courbe 1. Le conducteur 40 perçoit, à travers la lame 1, une image virtuelle 6, 7 derrière le pare-brise 8 et respectivement juste au dessus ou juste en dessous du capot 21. Ainsi, la partie supérieure 3 de la source lumineuse fait apparaître l'image ou l'information qu'elle a engendré, sous la forme d'une image virtuelle 6 dans le champ de vision de l'espace devant le véhicule automobile alors que la partie inférieure 4 de la source lumineuse fait apparaître l'image qu'elle a engendré, sous la forme d'une image virtuelle 7 en dehors, mais adjacent au champ de vision de l'espace devant le véhicule automobile.The display device of the invention, and more particularly the blade 1, is arranged so that the light source 3, 4 makes the information appear as a virtual image in two parts, an upper part 6 and a lower part 7 , the upper part 6 of the image appearing just above a lower limit 14 of a field of view on the space in front of the vehicle and the lower part 7 of the image appearing just below the lower limit 14 the field of vision on the space in front of the vehicle. The limit 14 corresponds to a straight line starting from the eyes 40 of a driver of the motor vehicle and passing through the highest point of the silhouette of the hood of the motor vehicle that presents itself to the driver of the vehicle. Thus, the device of the invention is located behind a steering wheel 30 of the motor vehicle and emits a virtual image 6, 1 by reflection of the light source 3, 4, for example a highly bright screen, a projection tube or an illuminated object , on the curved blade 1. The driver 40 perceives, through the blade 1, a virtual image 6, 7 behind the windshield 8 and respectively just above or just below the cover 21. Thus, the upper part 3 of the light source shows the image or the information that it has generated, in the form of a virtual image 6 in the field of view of the space in front of the motor vehicle whereas the lower part 4 of the light source reveals the image that it generated, in the form of a virtual image 7 outside, but adjacent to the field of view of the space in front of the motor vehicle.
En même temps, le dispositif d'affichage est disposé dans la planche de bord de manière que les rayons lumineux issus des parties supérieure et inférieure 3, 4 de la source lumineuse et traversant la lame 1 ne perturbent pas des piétons ni les conducteurs d'autres véhicules à l'extérieur de l'habitacle hébergeant le dispositif d'affichage de l'invention. Les rayons lumineux traversant la lame au dessus du tableau de bord seront ainsi dirigés vers le ciel.At the same time, the display device is arranged in the dashboard so that the light rays coming from the upper and lower portions 3, 4 of the light source and passing through the blade 1 do not disturb pedestrians or drivers. other vehicles outside the passenger compartment housing the display device of the invention. The light rays crossing the blade above the dashboard will thus be directed towards the sky.
Le dispositif de l'invention présente l'avantage de permettre d'afficher un ensemble d'informations sur une seule lame transparente et de pouvoir élargir le périmètre informatif du dispositif d'affichage à des informations sécuritaires. En effet, la partie inférieure 7 de l'image virtuelle, résultant de l'image émise par la partie inférieure 4 de la source lumineuse n'est pas en superposition avec l'espace devant le véhicule automobile. Ainsi, le contraste de la partie inférieure de l'image virtuelle est plus facile à maîtriser et peut alors être supérieure au contraste que l'on a obtenu avant l'invention.
Les figures 2 et 3 montrent respectivement isolément et par rapport à un emplacement dans une planche de bord et par rapport à un pare-brise 8 d'un véhicule automobile, les caractéristiques d'un premier mode de réalisation du dispositif de l'invention.The device of the invention has the advantage of making it possible to display a set of information on a single transparent slide and to be able to widen the information perimeter of the display device to safety information. Indeed, the lower part 7 of the virtual image, resulting from the image emitted by the lower part 4 of the light source is not superimposed with the space in front of the motor vehicle. Thus, the contrast of the lower part of the virtual image is easier to control and can be greater than the contrast obtained before the invention. Figures 2 and 3 respectively show separately and with respect to a location in a dashboard and with respect to a windshield 8 of a motor vehicle, the characteristics of a first embodiment of the device of the invention.
Le conducteur du véhicule automobile, représenté par ses yeux 40, observe la lame 1 et y voit apparaître comme une image virtuelle en deux parties 6, 7 une information ou des informations émises par les parties supérieure 3 et inférieure 4 de la source lumineuse. Cette situation est simplifiée d'avantage sur la figure 3 qui montre que l'image émise par la source lumineuse 3 est réfléchie par la lame courbe 1 vers le conducteur 40 qui a donc devant lui à la fois et sans changer de visé, l'image de l'espace devant le véhicule automobile, qui se présente à lui à travers le pare-brise, et l'image émise par la source lumineuse 3 et réfléchi par la lame courbe 1.The driver of the motor vehicle, represented by his eyes 40, observes the blade 1 and sees it appear as a virtual image in two parts 6, 7 information or information emitted by the upper 3 and lower 4 parts of the light source. This situation is further simplified in FIG. 3, which shows that the image emitted by the light source 3 is reflected by the curved blade 1 towards the driver 40 which therefore has in front of it at the same time and without changing the target, the image of the space in front of the motor vehicle, which presents itself to him through the windshield, and the image emitted by the light source 3 and reflected by the curved blade 1.
Cette disposition de base permet la réalisation de deux variantes du dispositif de l'affichage, la première en étant que la partie supérieure 3 et la partie inférieure 4 de la source lumineuse fonctionnent individuellement et au moins partiellement indépendamment l'une de l'autre et que de cette façon, la partie supérieure 3 des lettres lumineuses fait apparaître une première image virtuelle 6 au dessus de la limite inférieure 14 du champ de vision et que la partie inférieure 4 de la source lumineuse fait apparaître une seconde image virtuelle 7 au dessous de la limite inférieure 14 du champ de vision.This basic arrangement makes it possible to produce two variants of the device of the display, the first being that the upper part 3 and the lower part 4 of the light source function individually and at least partially independently of one another and that in this way, the upper part 3 of the luminous letters makes appear a first virtual image 6 above the lower limit 14 of the field of view and that the lower part 4 of the light source makes appear a second virtual image 7 below the lower limit 14 of the field of vision.
Selon la seconde variante de réalisation, le dispositif comprend une source lumineuse supplémentaire 5 destinée à engendrer une information supplémentaire à afficher. La source lumineuse supplémentaire 5 est disposée derrière la lame 1 et émet l'information supplémentaire (par exemple une alerte de défaut du véhicule) à travers la lame 1 directement vers le conducteur du véhicule.
Avantageusement, la source lumineuse supplémentaire 5 est disposée de manière que l'information supplémentaire apparaisse superposée à la partie inférieure 7 de l'image virtuelle ou de la seconde virtuelle 7 de l'information à afficher engendrée par la source lumineuse principale 3, 4.According to the second variant embodiment, the device comprises an additional light source 5 intended to generate additional information to be displayed. The additional light source 5 is disposed behind the blade 1 and transmits the additional information (for example a vehicle fault alert) through the blade 1 directly to the driver of the vehicle. Advantageously, the additional light source 5 is arranged in such a way that the additional information appears superimposed on the lower part 7 of the virtual image or the virtual second 7 of the information to be displayed generated by the main light source 3, 4.
La figure 4 représente un deuxième mode de réalisation du dispositif d'affichage de l'invention. Ce deuxième mode de réalisation correspond au premier dans la mesure où il comprend une lame 1, un boîtier et une source lumineuse engendrant l'information à afficher. La source lumineuse a une partie supérieure 3 et une partie inférieure 4, et le dispositif est agencé de façon que les images produites par les parties supérieures et inférieures 3, 4 de la source lumineuse apparaissent à un conducteur 40 d'un véhicule automobile comme des images virtuelles 6, 1.Figure 4 shows a second embodiment of the display device of the invention. This second embodiment corresponds to the first in that it comprises a blade 1, a housing and a light source generating the information to be displayed. The light source has an upper part 3 and a lower part 4, and the device is arranged so that the images produced by the upper and lower parts 3, 4 of the light source appear to a driver 40 of a motor vehicle as virtual images 6, 1.
Le deuxième mode de réalisation diffère du premier mode de réalisation en ce que la lame 1 comprend une zone supérieure 11 transparente permettant à la source lumineuse supérieure 3 de faire apparaître la partie supérieure 6 de l'image virtuelle ou la première image virtuelle 6 superposée à la vue réelle sur l'espace devant le véhicule automobile. La lame 1 comprend également une partie inférieure 12 partiellement transparente permettant à la source lumineuse inférieure 4 de faire apparaître une partie inférieure 7 de l'image virtuelle ou la seconde image virtuelle 7 sans superposition de la vue réelle sur l'espace devant le véhicule automobile.The second embodiment differs from the first embodiment in that the blade 1 comprises a transparent upper zone 11 allowing the upper light source 3 to reveal the upper part 6 of the virtual image or the first virtual image 6 superimposed on the real view of the space in front of the motor vehicle. The blade 1 also comprises a partially transparent lower portion 12 allowing the lower light source 4 to reveal a lower portion 7 of the virtual image or the second virtual image 7 without superposition of the real view on the space in front of the motor vehicle .
En raison de la présence d'une zone inférieure uniquement partiellement transparente, le boîtier référencé ici 23 a une forme simplifiée par rapport à celle du boîtier 2 du premier mode de réalisation. En effet, selon ce deuxième mode de réalisation, le boîtier 23 ne remonte pas derrière la lame 1.Due to the presence of a lower zone that is only partially transparent, the housing referenced here 23 has a simplified shape compared to that of the housing 2 of the first embodiment. Indeed, according to this second embodiment, the housing 23 does not go up behind the blade 1.
La figure 5 montre un troisième mode de réalisation du dispositif d'affichage de l'invention. Selon ce mode
de réalisation, le dispositif comprend, comme le premier mode de réalisation, une lame 1, un boîtier 2, une source lumineuse en deux parties avec une partie supérieure 3 et une partie inférieure 4 destinée à faire apparaître, à l'aide de la lame 1, une image virtuelle supérieure 6 et une image virtuelle inférieure 7 apparaissant à un observateur 40 tel le conducteur du véhicule. Le dispositif comprend en outre une source lumineuse supplémentaire 10 destinée à engendrer un affichage complémentaire traversant la lame 1 et se superposant à l'image virtuelle inférieure 7.Figure 5 shows a third embodiment of the display device of the invention. According to this mode embodiment, the device comprises, as the first embodiment, a blade 1, a housing 2, a light source in two parts with an upper portion 3 and a lower portion 4 intended to reveal, using the blade 1, a higher virtual image 6 and a lower virtual image 7 appearing to an observer 40 such as the driver of the vehicle. The device further comprises an additional light source 10 for generating a complementary display crossing the blade 1 and superimposed on the lower virtual image 7.
La source lumineuse 5 de la variante de réalisation du premier mode de réalisation tout comme la source lumineuse supplémentaire 10 du troisième mode de réalisation peuvent être utilisées pour superposer à l'image virtuelle inférieure 7 des alertes de défaut véhicule .
The light source 5 of the alternative embodiment of the first embodiment as well as the additional light source 10 of the third embodiment can be used to superimpose on the lower virtual image 7 of the vehicle fault alerts.
