une source de lumière (13), au moins une lentille (14) agencée pour recevoir une lumière (L1) émise par la source de lumière (13), caractérisé en ce que le dispositif comprend en outre, sur le chemin optique, un support transparent (15) pourvu d'une image du motif lumineux à projeter, la lentille (14) étant agencée entre la source de lumière (13) et le support transparent (15).a light source (13), at least one lens (14) arranged to receive light (L1) emitted by the light source (13), characterized in that the device further comprises, on the optical path, a support transparent (15) provided with an image of the light pattern to be projected, the lens (14) being arranged between the light source (13) and the transparent support (15).
Dispositif de projection pour véhicule [0001] La présente invention concerne de manière générale un dispositif de projection monté sur un véhicule automobile pour projeter un motif lumineux sur le sol à proximité du véhicule. La présente invention concerne en outre un véhicule équipé d’un tel dispositif ainsi qu’un procédé de sécurité pour véhicule.Projection device for vehicle The present invention relates generally to a projection device mounted on a motor vehicle for projecting a light pattern on the ground near the vehicle. The present invention further relates to a vehicle equipped with such a device as well as to a vehicle security method.
[0002] Il est connu dans l’art antérieur des dispositifs affichant ou projetant un motif lumineux sur le sol à proximité d’un véhicule. Le document WO2014206626 divulgue ainsi un dispositif pour véhicule capable de projeter un motif lumineux au sol.It is known in the prior art devices displaying or projecting a light pattern on the ground near a vehicle. Document WO2014206626 thus discloses a device for a vehicle capable of projecting a light pattern on the ground.
[0003] En contrepartie, ce système présente notamment l’inconvénient de comprendre une gamme de micro lentilles, ce qui est coûteux et complexe à mettre au point et fabriquer.In return, this system has the disadvantage of including a range of micro lenses, which is expensive and complex to develop and manufacture.
[0004] Un but de la présente invention est de répondre aux inconvénients du document de l’art antérieur mentionnés ci-dessus et en particulier, de proposer un dispositif de projection permettant de projeter ou d’afficher un motif lumineux au sol qui soit simple et peu coûteux et donc utilisable sur tout type de véhicule.An object of the present invention is to respond to the drawbacks of the prior art document mentioned above and in particular, to provide a projection device for projecting or displaying a light pattern on the ground which is simple and inexpensive and therefore usable on any type of vehicle.
[0005] Un but additionnel de la présente invention est de proposer un dispositif de projection dont le motif projeté puisse être aisément échangé afin de permettre une personnalisation ou afin de tenir compte de particularités culturelles et/ou réglementaires de différents pays.An additional object of the present invention is to provide a projection device whose projected pattern can be easily exchanged to allow personalization or to take into account cultural and / or regulatory features of different countries.
[0006] Pour cela un premier aspect de l’invention concerne un dispositif de projection pour véhicule, ledit dispositif étant adapté pour projeter un motif lumineux au sol à proximité du véhicule et comprenant :For this, a first aspect of the invention relates to a projection device for a vehicle, said device being adapted to project a light pattern on the ground near the vehicle and comprising:
• une source de lumière,• a light source,
-2 • au moins une lentille agencée pour recevoir une lumière émise par la source de lumière, caractérisé en ce que le dispositif de projection comprend en outre, sur le chemin optique, un support transparent pourvu d’une image du motif lumineux à projeter, la lentille étant agencée entre la source de lumière et le support transparent.-2 • at least one lens arranged to receive a light emitted by the light source, characterized in that the projection device further comprises, on the optical path, a transparent support provided with an image of the light pattern to be projected, the lens being arranged between the light source and the transparent support.
[0007] Ainsi, un tel dispositif de projection est simple à fabriquer et à installer sur un véhicule et n’implique qu’un coût limité de fabrication et de mise au point.Thus, such a projection device is simple to manufacture and install on a vehicle and involves only a limited cost of manufacture and development.
[0008] Avantageusement, ladite image du motif lumineux est une image anamorphosée ou anamorphose, c’est-à-dire que l’image visible sur le support transparent est une image déformée par rapport au motif lumineux visible sur le sol. Ceci permet de compenser un angle d’inclinaison du chemin optique par rapport au sol et ainsi d’effectuer une projection optimale d’un motif lumineux, c’est-à-dire sans déformation disgracieuse et le plus lisible possible pour l’usager du véhicule.Advantageously, said image of the light pattern is an anamorphic or anamorphic image, that is to say that the image visible on the transparent support is an image distorted with respect to the light pattern visible on the ground. This makes it possible to compensate for an angle of inclination of the optical path relative to the ground and thus to carry out an optimal projection of a light pattern, that is to say without unsightly deformation and as legible as possible for the user of the vehicle.
[0009] Avantageusement, le motif lumineux définit une zone de sécurité pour un usager dudit véhicule. Ceci permet de renforcer la sécurité de l’usager par exemple en situation d’urgence ou de détresse, à la fois en incitant l’usager à rester à proximité du véhicule, c’est-à-dire au sein du motif lumineux, et en incitant les autres véhicules à s’écarter suffisamment du véhicule en détresse ou en situation d’urgence. Par exemple, le motif lumineux peut comprendre des lignes continues ou pointillées d’une couleur associée au danger ou à la sécurité, telles que rouge, orange ou jaune. En outre, le motif lumineux peut comprendre des flèches à destination de l’usager du véhicule ou des autres véhicules, des pictogrammes de sécurité ou de danger, des messages écrits ou des combinaisons de ceux-ci.Advantageously, the light pattern defines a safety zone for a user of said vehicle. This makes it possible to reinforce the safety of the user, for example in an emergency or distress situation, both by encouraging the user to remain close to the vehicle, that is to say within the light pattern, and by encouraging other vehicles to move enough away from the vehicle in distress or in an emergency. For example, the light pattern may include solid or dotted lines of a color associated with danger or safety, such as red, orange or yellow. In addition, the light pattern may include arrows intended for the user of the vehicle or of other vehicles, safety or danger pictograms, written messages or combinations thereof.
[0010] Alternativement, le motif lumineux définit une zone de bienvenue ou de confort non liée à une situation d’urgence ou de détresse, comprenant par exemple un message de bienvenue ou d’au revoir, un logo,Alternatively, the light pattern defines a welcome or comfort zone not linked to an emergency or distress situation, for example comprising a welcome or goodbye message, a logo,
-3le nom d’un usager du véhicule ou encore une image ou un message amusant, attirant ou effrayant. Une telle zone de bienvenue ou de confort peut être projetée dans toute couleur appropriée, par exemple des couleurs neutres comme le bleu, le vert, le violet ou le rose.-3the name of a vehicle user or a funny, attractive or scary image or message. Such a welcome or comfort zone can be projected in any suitable color, for example neutral colors such as blue, green, purple or pink.
[0011] Avantageusement, le support transparent pourvu d’une image du motif lumineux à projeter est une diapositive. Ceci permet de réduire encore le coût du dispositif de projection, puisque les diapositives sont imprimables à bas prix.Advantageously, the transparent support provided with an image of the light pattern to be projected is a slide. This further reduces the cost of the projection device, since the slides are printable at low cost.
[0012] De manière spécialement avantageuse, le dispositif de projection comprend un portoir pour recevoir le support transparent de manière amovible. Ainsi, le support transparent peut être sélectionnée en usine ou bien échangé à l’importation d’un véhicule intégrant le dispositif de projection afin de tenir compte de l’usage envisagé du dispositif de projection ainsi que des particularités culturelles et/ou réglementaires de chaque pays. Par exemple, le motif lumineux peut être personnalisé selon le désir de l’acheteur ou de l’usager du véhicule ou bien un message de sécurité peut être traduit dans une langue adéquate.Especially advantageously, the projection device comprises a rack for receiving the transparent support in a removable manner. Thus, the transparent support can be selected at the factory or exchanged when importing a vehicle integrating the projection device in order to take into account the intended use of the projection device as well as the cultural and / or regulatory particularities of each country. For example, the light pattern can be personalized according to the wishes of the buyer or the user of the vehicle, or a safety message can be translated into an appropriate language.
[0013] Avantageusement, la lentille est une lentille convergente afin de faire converger la lumière de la source lumineuse sur le support transparent ou sur l’image du motif lumineux à projeter, afin de maximiser la luminosité du motif lumineux.Advantageously, the lens is a converging lens in order to converge the light of the light source on the transparent support or on the image of the light pattern to be projected, in order to maximize the brightness of the light pattern.
[0014] Avantageusement, le dispositif de projection comprend au moins une autre lentille située sur le chemin optique en aval du support transparent, c’est-à-dire située entre ladite diapositive et le sol. Une telle au moins une autre lentille permet d’optimiser l’affichage du motif lumineux au sol et/ou de produire un effet d’optique sur ledit motif lumineux.Advantageously, the projection device comprises at least one other lens located on the optical path downstream of the transparent support, that is to say located between said slide and the ground. Such at least one other lens makes it possible to optimize the display of the light pattern on the ground and / or to produce an optical effect on said light pattern.
[0015] Avantageusement, la source de lumière est une source DEL, c’est-à-dire une diode électroluminescente. Une telle source de lumière est peu coûteuse et résistante et contribue ainsi à rendre le dispositif de projection fiable et peu coûteux. En outre, le dispositif de projection peutAdvantageously, the light source is an LED source, that is to say a light emitting diode. Such a light source is inexpensive and resistant and thus contributes to making the projection device reliable and inexpensive. In addition, the projection device can
-4 comprendre plusieurs sources lumineuses sous la forme de plusieurs DEL de couleurs différentes, par exemple pour adapter le motif lumineux à une situation de projection. Ainsi, un motif lumineux bleu peut être projeté dans une situation normale du véhicule et un motif lumineux rouge peut être projeté lors d’une situation de détresse du véhicule.-4 include several light sources in the form of several LEDs of different colors, for example to adapt the light pattern to a projection situation. Thus, a blue light pattern can be projected in a normal vehicle situation and a red light pattern can be projected during a vehicle distress situation.
[0016] Un second aspect de l’invention est un véhicule comportant au moins un dispositif de projection selon le premier aspect de l’invention.A second aspect of the invention is a vehicle comprising at least one projection device according to the first aspect of the invention.
[0017] Avantageusement, ledit au moins un dispositif de projection est fixé sous une porte avant dudit véhicule, par exemple la porte conducteur. Alternativement, ledit dispositif peut être fixé sur une porte arrière d’un véhicule, par exemple dans le cas d’une limousine ou d’un véhicule de transport en commun.Advantageously, said at least one projection device is fixed under a front door of said vehicle, for example the driver's door. Alternatively, said device can be fixed to a rear door of a vehicle, for example in the case of a limousine or a public transport vehicle.
[0018] Avantageusement, ledit véhicule comprend plusieurs dispositifs de projection, par exemple un dispositif de projection sous chaque porte.Advantageously, said vehicle comprises several projection devices, for example a projection device under each door.
[0019] Un dernier aspect de l’invention concerne un procédé de sécurité pour un véhicule comprenant un dispositif de projection selon le premier aspect de l’invention, ledit procédé comprenant les étapes consistant à :A last aspect of the invention relates to a safety method for a vehicle comprising a projection device according to the first aspect of the invention, said method comprising the steps consisting in:
- détecter le déclenchement d’un signal de détresse du véhicule,- detect the triggering of a vehicle distress signal,
- projeter au sol un motif lumineux en forme de zone de sécurité à proximité du véhicule grâce au dit dispositif de projection.- Projecting a light pattern on the ground in the form of a safety zone near the vehicle thanks to said projection device.
[0020] D’autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d’un mode de réalisation de l’invention donné à titre d’exemple nullement limitatif et illustré par les dessins annexés, dans lesquels :Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the accompanying drawings, wherein :
la figure 1 représente une vue en coupe d’un dispositif de projection selon le premier aspect de l’invention.Figure 1 shows a sectional view of a projection device according to the first aspect of the invention.
-5la figure 2 représente une vue de dessus d’un véhicule incluant un dispositif de projection selon la figure 1 de chaque côté du véhicule.FIG. 2 represents a top view of a vehicle including a projection device according to FIG. 1 on each side of the vehicle.
[0021] La figure 1 représente un dispositif de projection 10 selon la présente invention. Le dispositif de projection comprend un boitier 11 incluant, de droite à gauche et aligné sur un chemin optique, un circuit imprimé 12, une source de lumière 13, une lentille 14, un support transparent 15 sous la forme d’une diapositive, une autre lentille 16 et une surface transparente de projection 17.Figure 1 shows a projection device 10 according to the present invention. The projection device comprises a box 11 including, from right to left and aligned on an optical path, a printed circuit 12, a light source 13, a lens 14, a transparent support 15 in the form of a slide, another lens 16 and a transparent projection surface 17.
[0022] Le boitier 11 est un boitier de forme cylindrique en métal ou en plastique rigide de type ABS, ou bien en matière transparente telle que du verre antichoc ou du polycarbonate. Par exemple, il est constitué par deux demi-boitiers emboîtables et comprend une ouverture distale par rapport à la source lumineuse, sur le chemin optique ainsi que des ouvertures ou interfaces permettant une fixation au véhicule et une connexion au réseau électrique du véhicule.The housing 11 is a cylindrical housing made of metal or rigid plastic of the ABS type, or else of transparent material such as shockproof glass or polycarbonate. For example, it is constituted by two interlocking half-boxes and includes an opening distal to the light source, on the optical path as well as openings or interfaces allowing attachment to the vehicle and connection to the vehicle electrical network.
[0023] Le circuit imprimé 12 accueille la source de lumière 13 qui est fixée ou soudée à sa surface, et comprend en outre un circuit électronique de commande de façon à commander l’allumage et optionnellement l’intensité de la source de lumière. Le circuit imprimé 12 comprend également une alimentation électrique et un système de connexion filaire ou sans-fil (tel que Bluetooth ou ZigBee) permettant l’échange de données entre le circuit imprimé 12 et le système embarqué du véhicule.The printed circuit 12 receives the light source 13 which is fixed or welded to its surface, and further comprises an electronic control circuit so as to control the ignition and optionally the intensity of the light source. The printed circuit 12 also includes a power supply and a wired or wireless connection system (such as Bluetooth or ZigBee) allowing the exchange of data between the printed circuit 12 and the vehicle's on-board system.
[0024] La source lumineuse 13 est une diode électroluminescente ou DEL de type commercial, préférentiellement de couleur blanche, mais éventuellement colorée, de préférence assez puissante pour émettre une lumière visible en plein jour.The light source 13 is a light emitting diode or LED of commercial type, preferably white, but possibly colored, preferably powerful enough to emit visible light in broad daylight.
[0025] La lentille 14 est une lentille convergente standard, préférentiellement disposée de telle sorte que la source lumineuse 13 soit dans le plan focal de la lentille 14.The lens 14 is a standard converging lens, preferably arranged so that the light source 13 is in the focal plane of the lens 14.
-6[0026] Le support transparent 15 est une diapositive, c’est-à-dire un film transparent comprenant une image du motif lumineux à projeter. Dans le mode de réalisation décrit, il s’agit d’une anamorphose, c’est-à-dire une image déformée, de façon à tenir compte de l’angle de projection et permettant ainsi de projeter un motif lumineux sous la forme d’une zone de sécurité lisible à proximité du véhicule (voir Fig. 2 décrite ci-après). Ainsi, l’image du motif lumineux imprimée dans la diapositive n’est pas aisément reconnaissable quand elle n’est pas projetée au sol.The transparent support 15 is a slide, that is to say a transparent film comprising an image of the light pattern to be projected. In the embodiment described, this is an anamorphosis, that is to say a distorted image, so as to take account of the projection angle and thus making it possible to project a light pattern in the form of '' a readable safety zone near the vehicle (see Fig. 2 described below). Thus, the image of the light pattern printed in the slide is not easily recognizable when it is not projected onto the ground.
[0027] La diapositive est reçue de façon amovible sur un portoir (non représenté). Ainsi, la diapositive peut être facilement sélectionnée par le client ou par l’importateur d’un véhicule, selon l’utilisation prévue du motif lumineux (de sécurité, de détresse ou de confort) ou selon des contraintes culturelles ou réglementaires. Alternativement, le portoir est un carrousel tel que connu de l’état de la technique permettant la sélection d’une diapositive en fonction de la situation.The slide is received removably on a rack (not shown). Thus, the slide can be easily selected by the customer or the importer of a vehicle, depending on the intended use of the light pattern (security, distress or comfort) or according to cultural or regulatory constraints. Alternatively, the rack is a carousel as known from the prior art allowing the selection of a slide according to the situation.
[0028] L’autre lentille 16 est une lentille standard légèrement divergente. Alternativement, elle peut être remplacée par un jeu de lentille de façon à améliorer l’image projetée, comme connu de l’homme du métier.The other lens 16 is a slightly diverging standard lens. Alternatively, it can be replaced by a set of lenses so as to improve the projected image, as known to those skilled in the art.
[0029] Enfin, la surface transparente de projection 17 est faite de polycarbonate ou de verre antichoc, de façon optimiser la quantité de lumière projetée.Finally, the transparent projection surface 17 is made of polycarbonate or shockproof glass, so as to optimize the amount of light projected.
[0030] En fonctionnement, quand le circuit imprimé 12 reçoit une commande d’allumage de la part du système embarqué du véhicule, par exemple suite à une commande du conducteur, un déclenchement d’un signal de détresse du véhicule (aussi appelé warnings), la détection d’un dysfonctionnement moteur et/ou l’ouverture d’une porte du véhicule, une alimentation électrique est fournie à la source lumineuse 13 qui produit une première lumière L1. Cette lumière L1 est convergée vers l’infini en une deuxième lumière L2 par la lentille 14 et passe au travers du support transparent 15 et donc à travers l’image anamorphosée du motif lumineux àIn operation, when the printed circuit 12 receives an ignition command from the vehicle on-board system, for example following a command from the driver, triggering of a vehicle distress signal (also called warnings) , the detection of an engine malfunction and / or the opening of a vehicle door, an electrical supply is supplied to the light source 13 which produces a first light L1. This light L1 is converged towards infinity into a second light L2 by the lens 14 and passes through the transparent support 15 and therefore through the anamorphic image of the light pattern at
-7 projeter.
