Description

"Dispositif de détection comportant des moyens de nettoyage d'une fenêtre transparente." "Detection device comprising means for cleaning a transparent window."
L'invention propose un dispositif de détection, qui comporte une caméra d'axe principal longitudinal, qui est globalement orientée vers l'arrière et qui est agencée à l'intérieur d'un boîtier fermé hermétiquement, le boîtier comportant une paroi verticale transversale arrière qui porte une fenêtre transparente, agencée dans au moins une partie du champ de la caméra, le dispositif de détection comportant des moyens de nettoyage de la fenêtre qui comportent notamment des moyens de projection d'un fluide sous pression sur la face externe de la fenêtre.The invention provides a detection device, which comprises a camera with a longitudinal main axis, which is generally oriented towards the rear and which is arranged inside a hermetically closed casing, the casing comprising a rear transverse vertical wall. which carries a transparent window, arranged in at least part of the field of the camera, the detection device comprising means for cleaning the window which in particular comprise means for projecting a fluid under pressure onto the external face of the window .
Les dispositifs d'aide à la conduite et notamment d'aide aux manœuvres de parking, ou parcage, sont principalement constitués de deux parties, à savoir un dispositif de détection des obstacles, et un dispositif d'indication à l'utilisateur de la proximité des obstacles.The driving assistance devices and in particular of assistance for parking or parking maneuvers, mainly consist of two parts, namely an obstacle detection device, and a device for indicating to the user of the proximity. obstacles.
Le dispositif de détection permet de détecter les obstacles que le conducteur ne peut pas voir, notamment parce que ces obstacles sont relativement bas et qu'ils s'étendent, en général, à la même hauteur que le pare-chocs du véhicule.The detection device makes it possible to detect obstacles that the driver cannot see, in particular because these obstacles are relatively low and that they extend, in general, at the same height as the bumper of the vehicle.
Pour cela, il a été proposé d'agencer le dispositif de détection dans un module qui est en général intégré au pare- chocs ou au dispositif d'éclairage de la plaque minéralogique. Le dispositif de détection comporte, d'une manière générale, une caméra ou un dispositif équivalent. Cet appareil électronique étant particulièrement sensible, il est nécessaire de le protéger des agressions extérieures et des divers polluants pouvant l'endommager comme par exemple les projections d'eau ou diverses boues.For this, it has been proposed to arrange the detection device in a module which is generally integrated into the bumper or the lighting device of the number plate. The detection device generally comprises a camera or an equivalent device. This electronic device being particularly sensitive, it is necessary to protect it from external aggressions and various pollutants which can damage it such as for example water splashes or various sludges.
Dans ce but, la caméra est agencée à l'intérieur d'un boîtier fermé hermétiquement, qui comporte une fenêtre transparente, agencée dans le champ de la caméra. Cependant, le boîtier, et notamment la fenêtre, est exposé aux divers polluants qui se déposent sur les faces extérieures de celui-ci en formant un film de pollution qui s'opacifie de plus en plus lors de l'utilisation du véhicule. Ce film de pollution qui se forme sur la face externe de la fenêtre réduit l'efficacité de la caméra.For this purpose, the camera is arranged inside a hermetically closed housing, which has a transparent window, arranged in the field of the camera. However, the housing, and in particular the window, is exposed to the various pollutants which are deposited on the external faces of the latter, forming a pollution film which becomes more and more cloudy when the vehicle is used. This pollution film which forms on the external face of the window reduces the efficiency of the camera.
Il est donc nécessaire de restaurer la transparence initiale de la face externe de la fenêtre pour conserver l'efficacité de la caméra dans toutes les conditions de vie du véhicule. II est connu d'utiliser des moyens de pulvérisation d'eau sous pression sur la face externe de la fenêtre pour la nettoyer. Cependant, il s'avère que l'efficacité de ces moyens de pulvérisation est limitée et qu'ils ne permettent pas de supprimer les polluants dits tenaces, qui adhèrent fortement à la face externe de la fenêtre, comme par exemple les boues ou les fientes.It is therefore necessary to restore the initial transparency of the external face of the window in order to maintain the effectiveness of the camera in all the conditions of life of the vehicle. It is known to use means for spraying pressurized water on the external face of the window to clean it. However, it turns out that the effectiveness of these spraying means is limited and that they do not make it possible to remove the so-called stubborn pollutants, which adhere strongly to the external face of the window, such as for example mud or droppings. .
Par ailleurs, bien que le boîtier à l'intérieur duquel la caméra est agencée est fermé hermétiquement, des particules, qui sont déjà présentes dans le boîtier, ou bien qui se forment progressivement, se déposent sur la face interne de la fenêtre.Furthermore, although the housing inside which the camera is arranged is hermetically closed, particles, which are already present in the housing, or else which are gradually formed, are deposited on the internal face of the window.
Le nettoyage de la face interne de la fenêtre ne peut se faire par la projection d'un liquide car celui-ci risquerait d'endommager les divers appareils électroniques en provoquant des courts-circuits. En outre, le document DE-A1 -100.12.004 décrit un dispositif de détection comportant des moyens de nettoyage d'éléments optiques dans les véhicules automobiles, particulièrement des couvercles, d'une caméra. Ces moyens de nettoyage comportent des moyens de diffusion d'un gaz dirigé vers le couvercle de façon à empêcher tout air environnant d'atteindre la face transparente du couvercle pendant le mouvement du véhicule. La diffusion du gaz n'est efficace que lorsque le véhicule est en mouvement. Par conséquent, il ne permet pas la suppression de la totalité des polluants sur les faces interne et/ou externe de la fenêtre et en particulier lorsque le véhicule est à l'arrêt.The cleaning of the internal face of the window cannot be done by the projection of a liquid because this would risk damaging the various electronic devices by causing short-circuits. In addition, document DE-A1 -100.12.004 describes a detection device comprising means for cleaning optical elements in motor vehicles, particularly covers, of a camera. These cleaning means comprise means for diffusing a gas directed towards the cover so as to prevent any surrounding air from reaching the transparent face of the cover during the movement of the vehicle. Diffusion of gas is only effective when the vehicle is in motion. Consequently, it does not allow the removal of all the pollutants on the internal and / or external faces of the window and in particular when the vehicle is stationary.
Pour remédier à ces inconvénients, l'invention a pour but de proposer un dispositif de détection qui permette la suppression de la totalité des polluants qui peuvent se déposer sur les faces interne et/ou externe de la fenêtre, que le véhicule soit à l'arrêt ou en mouvement.To remedy these drawbacks, the object of the invention is to propose a detection device which allows the removal of all the pollutants which may be deposited on the internal and / or external faces of the window, whether the vehicle is at stopped or moving.
Dans ce but, l'invention propose un dispositif de détection, du type décrit précédemment, caractérisé en ce que les moyens de nettoyage de la fenêtre comportent en outre un revêtement photocatalytique sur la face externe de la fenêtre.For this purpose, the invention provides a detection device, of the type described above, characterized in that the window cleaning means also comprise a photocatalytic coating on the external face of the window.

Dans la description qui va suivre, des éléments identiques, similaires ou analogues seront désignés par les mêmes chiffres de référence.In the description which follows, identical, similar or analogous elements will be designated by the same reference numbers.
On a représenté à la figure 1 le dispositif de détection 10, qui fait partie d'un module d'équipement d'un véhicule automobileFIG. 1 shows the detection device 10, which is part of an equipment module of a motor vehicle
12 comportant notamment la fonction d'éclairage de la plaque minéralogique arrière 14, et qui comporte des moyens (non représentés) pour sa fixation et son raccordement électrique au module d'équipement. Le module de détection 10, qui est ici agencé sur le hayon arrière 16 du véhicule automobile 12, comporte une caméra 18 dont l'axe A du champ de vision 19 est orienté globalement horizontalement vers l'arrière, et un feu d'éclairage 20 qui permet d'illuminer les divers obstacles pouvant entrer dans le champ de la caméra lorsque l'éclairage naturel est insuffisant.12 comprising in particular the lighting function of the rear number plate 14, and which comprises means (not shown) for its fixing and its electrical connection to the equipment module. The detection module 10, which is here arranged on the tailgate 16 of the motor vehicle 12, comprises a camera 18 whose axis A of the field of vision 19 is oriented generally horizontally towards the rear, and a lighting light 20 which makes it possible to illuminate the various obstacles which can enter the field of the camera when the natural light is insufficient.
Pour leur protection contre toute agression provenant de l'extérieur, la caméra 18 et le feu 20 sont agencés à l'intérieur d'un boîtier 22 qui est fermé hermétiquement.For their protection against any attack from the outside, the camera 18 and the fire 20 are arranged inside a housing 22 which is hermetically closed.
Le boîtier 22 comporte une paroi verticale transversale arrière 24 située en vis-à-vis de l'optique 21 de la caméra 18 qui porte deux fenêtres 26, agencées respectivement dans le champ de la caméra 18 et dans le champ du feu 20. Les fenêtres 26 sont réalisées dans un matériau transparent, par exemple en verre minéral ou organique, et elles sont ici de forme circulaire. Cependant, il sera compris que les fenêtres 26 peuvent être de toute autre forme, sans sortir du domaine de l'invention.The housing 22 includes a rear transverse vertical wall 24 situated opposite the optics 21 of the camera 18 which carries two windows 26, arranged respectively in the field of the camera 18 and in the field of fire 20. The windows 26 are made of a transparent material, for example mineral or organic glass, and are here circular in shape. However, it will be understood that the windows 26 can be of any other shape, without departing from the scope of the invention.
De plus, dans la description qui va suivre, il sera fait référence à une seule fenêtre 26, à savoir celle de la caméra 18. Cependant, il sera compris que cette description s'applique indifféremment à l'une ou l'autre des deux fenêtres 26.In addition, in the description which follows, reference will be made to a single window 26, namely that of the camera 18. However, it will be understood that this description applies equally to one or the other of the two windows 26.
L'étanchéité du boîtier 22 est réalisée, au niveau de la fenêtre 26, par l'intermédiaire d'un joint d'étanchéité 32 qui recouvre la totalité du bord périphérique de la fenêtre 26, et selon un mode de réalisation, ce joint d'étanchéité 32 est surmoulé sur le bord de la fenêtre 26.The housing 22 is sealed at the window 26 by means of a seal 32 which covers the entire peripheral edge of the window 26, and according to one embodiment, this seal d the seal 32 is molded onto the edge of the window 26.
Lorsque le véhicule 12 est en mouvement, des turbulences aérodynamiques se forment dans son sillage. Ces turbulences transportent de nombreux polluants tels que des poussières, de l'eau ou des boues, qui viennent se déposer sur la face externe 24e de la paroi arrière 24, et donc sur la face externe 26e de la fenêtre 26.When the vehicle 12 is in motion, aerodynamic turbulence forms in its wake. These turbulences transport numerous pollutants such as dust, water or sludge, which are deposited on the external face 24e of the rear wall 24, and therefore on the external face 26e of the window 26.
Pour supprimer ces polluants, il est prévu de projeter de l'eau ou de l'air sous pression, par l'intermédiaire d'un gicleur 28, sur la face externe 26e de la fenêtre 26.To remove these pollutants, it is planned to spray water or pressurized air, via a nozzle 28, on the external face 26e of the window 26.
Cependant, l'utilisation du gicleur 28 n'est pas suffisamment efficace pour supprimer les polluants dits tenaces.However, the use of the nozzle 28 is not effective enough to remove so-called stubborn pollutants.
De plus, comme on l'a dit plus haut, bien que le boîtier 22 soit fermé hermétiquement, certains polluants, notamment des poussières, peuvent se déposer sur la face interne 26i de la fenêtre 26. C'est pourquoi, et conformément à l'invention, un revêtement 30 est appliqué sur la face externe 26e, ce revêtement 30 comportant un traitement photocatalytique, qui permet de nettoyer la fenêtre 26 en utilisant la lumière ambiante. Cependant, il se peut que l'éclairage extérieur soit insuffisant pour activer la photocatalyse. C'est pourquoi, selon une variante de réalisation de l'invention, représenté à la figure 4, une source lumineuse 20 est agencée dans le boîtier, de manière à générer un flux lumineux en direction de la fenêtre 26, lorsque l'éclairage extérieur est insuffisant.In addition, as mentioned above, although the housing 22 is hermetically closed, certain pollutants, in particular dust, can be deposited on the internal face 26i of the window 26. This is why, and in accordance with the he invention, a coating 30 is applied to the outer face 26e, this coating 30 comprising a photocatalytic treatment, which makes it possible to clean the window 26 using ambient light. However, the exterior lighting may not be sufficient to activate the photocatalysis. This is why, according to an alternative embodiment of the invention, shown in FIG. 4, a light source 20 is arranged in the housing, so generating a luminous flux in the direction of the window 26, when the exterior lighting is insufficient.
Par ailleurs, selon un autre mode de réalisation de l'invention, la source lumineuse 20 est le feu d'éclairage 20, et elle est agencée en formant une couronne entourant l'optique 21 de la caméra 18.Furthermore, according to another embodiment of the invention, the light source 20 is the lighting light 20, and it is arranged by forming a crown surrounding the optics 21 of the camera 18.
Ce mode de réalisation permet de concevoir un dispositif de détection 10 de dimensions réduites, et qui ne comporte qu'une seule fenêtre 26, ce qui réduit fortement la surface à nettoyer.This embodiment makes it possible to design a detection device 10 of reduced dimensions, and which has only one window 26, which greatly reduces the surface to be cleaned.
Le flux lumineux permettant d'activer la photocatalyse peut aussi être généré par un élément distinct du feu d'éclairage 20.The luminous flux making it possible to activate the photocatalysis can also be generated by an element separate from the lighting lamp 20.
Dans ce cas, et selon un mode de réalisation, la longueur d'onde du flux lumineux généré est celle permettant d'activer la photocatalyse, ce qui permet, selon la longueur d'onde, de générer un flux lumineux qui ne risquerait pas de gêner ni d'éblouir un automobiliste situé derrière le véhicule 12.In this case, and according to one embodiment, the wavelength of the light flux generated is that making it possible to activate the photocatalysis, which makes it possible, according to the wavelength, to generate a light flux which would not risk obstruct or dazzle a motorist behind the vehicle 12.
La source lumineuse 20 peut être activée par différents moyens, par exemple lorsque le conducteur enclenche la marche arrière du véhicule 12. Cependant, selon un autre mode de réalisation de l'invention, le module de détection 10 comporte un élément électronique (non représenté) qui comporte notamment un capteur de luminosité, qui permet d'activer automatiquement la source lumineuse 20. Ainsi, la photocatalyse peut être activée automatiquement en fonction du niveau de pollution de la fenêtre 26, ou bien en fonction de la luminosité ambiante.The light source 20 can be activated by various means, for example when the driver engages the vehicle in reverse 12. However, according to another embodiment of the invention, the detection module 10 includes an electronic element (not shown) which includes a light sensor, which automatically activates the light source 20. Thus, photocatalysis can be activated automatically depending on the pollution level of the window 26, or depending on the ambient light.
Selon une variante de réalisation, l'élément électronique qui permet d'activer la source lumineuse 20 permet aussi d'activer les moyens de projection 28 du fluide sous pression, simultanément à la source lumineuse 20, ou bien, selon une autre variante, l'élément électronique permet d'activer sélectivement les moyens de projection ou la source lumineuse 20. Selon un autre mode de réalisation de l'invention, le revêtement 30 comporte un deuxième traitement additionnel au traitement photocatalytique, qui est un traitement hydrophile, ou un traitement hydrophobe, permettant de supprimer les projections d'eau ou bien d'empêcher la formation de buée sur les faces internes ou externes 26e, 26i, de la fenêtre 26.According to a variant embodiment, the electronic element which makes it possible to activate the light source 20 also makes it possible to activate the means 28 for projecting the fluid under pressure, simultaneously with the light source 20, or alternatively, according to another variant, the the electronic element makes it possible to selectively activate the projection means or the light source 20. According to another embodiment of the invention, the coating 30 comprises a second treatment additional to the photocatalytic treatment, which is a hydrophilic treatment, or a hydrophobic treatment, making it possible to suppress water splashes or else to prevent the formation of fogging on the internal or external faces 26e, 26i, of the window 26.
Selon un autre mode de réalisation de l'invention, le revêtement 30 comporte sur la face interne 26i de la fenêtre 26 seulement un traitement qui est un traitement hydrophile permettant d'empêcher la formation de buée sur la face interneAccording to another embodiment of the invention, the coating 30 comprises on the internal face 26i of the window 26 only a treatment which is a hydrophilic treatment making it possible to prevent the formation of fogging on the internal face
26i.26i.
Selon un mode de réalisation de l'invention, un revêtement intérieur est également appliqué sur la face interne 26i de la fenêtre 26. En effet, malgré le deuxième traitement hydrophile ou hydrophobe du revêtement 30, ou bien en l'absence de ce deuxième traitement, il se peut que du givre, de la neige de la buée se déposent sur les faces internes 26i ou externes 26e de la fenêtre 26, en cas d'une température extérieure faible. A cet effet, chaque fenêtre 26 comporte des moyens de chauffage de la fenêtre 26 à une température permettant la fonte, voire l'évaporation de ces polluants.According to one embodiment of the invention, an interior coating is also applied to the internal face 26i of the window 26. In fact, despite the second hydrophilic or hydrophobic treatment of the coating 30, or else in the absence of this second treatment , it may be that frost, snow from the mist is deposited on the internal 26i or external 26e faces 26e of the window 26, in the event of a low outside temperature. To this end, each window 26 comprises means for heating the window 26 to a temperature allowing the melting, or even the evaporation, of these pollutants.
À cet effet, selon un mode de réalisation de l'invention, la fenêtre 26 est constituée de deux plaques transparentes transversales parallèles 34a, 34b qui sont accolées par leurs faces transversales en vis-à-vis, à la manière d'un double vitrage, et un élément de chauffage 36 est interposé entre les deux plaques 34a, 34b.To this end, according to one embodiment of the invention, the window 26 consists of two parallel transverse transparent plates 34a, 34b which are joined by their transverse faces opposite, in the manner of double glazing , and a heating element 36 is interposed between the two plates 34a, 34b.
Selon un autre mode de réalisation de l'invention représenté à la figure 3, la fenêtre 26 consiste en une seule plaque transparente transversale, sur la face interne 26i de laquelle l'élément de chauffage 36 est agencé.According to another embodiment of the invention shown in Figure 3, the window 26 consists of a single transverse transparent plate, on the internal face 26i of which the heating element 36 is arranged.
Selon un mode préféré de réalisation de l'invention, l'élément de chauffage 36 consiste en un film chauffant qui est lui aussi transparent. Ainsi, le film chauffant 36 recouvre la totalité de la surface de la fenêtre 26 pour obtenir une répartition homogène du chauffage de la fenêtre 26.According to a preferred embodiment of the invention, the heating element 36 consists of a heating film which is itself also transparent. Thus, the heating film 36 covers the entire surface of the window 26 in order to obtain a uniform distribution of the heating of the window 26.
Selon une variante de réalisation de l'invention (non représenté), l'élément de chauffage 36 est un fil résistif qui s'étend à proximité du bord périphérique de la fenêtre 26, en formant globalement une boucle fermée.According to an alternative embodiment of the invention (not shown), the heating element 36 is a resistive wire which extends near the peripheral edge of the window 26, generally forming a closed loop.
De plus, lorsque le joint d'étanchéité est surmoulé sur le bord de la fenêtre 26, il est en même temps surmoulé autour des moyens de raccordement électrique de l'élément de chauffage 36, notamment lorsque la fenêtre 26 est constituée de deux plaques transversales 34a, 34b. Les moyens de raccordement peuvent comporter des fils électriques et/ou des connecteurs pour connecter l'élément de chauffage 36 au système électrique d'un véhicule automobile.In addition, when the seal is overmolded on the edge of the window 26, it is at the same time overmolded around the electrical connection means of the heating element 36, in particular when the window 26 consists of two transverse plates. 34a, 34b. The connection means may include electrical wires and / or connectors for connecting the heating element 36 to the electrical system of a motor vehicle.
Comme on l'a dit plus haut, lorsque le véhicule 12 est en mouvement, les turbulences qui se forment à l'arrière transportent divers polluants vers la face externe 26e de chaque fenêtre 26. Ainsi, pour limiter la quantité de polluants qui proviennent de ces turbulences, il est nécessaire de limiter la formation de ces turbulences.As mentioned above, when the vehicle 12 is in motion, the turbulences which form at the rear transport various pollutants towards the external face 26e of each window 26. Thus, to limit the quantity of pollutants which come from these turbulences, it is necessary to limit the formation of these turbulences.
A cet effet, comme on peut le voir à la figure 2, le boîtier 22 comporte un déflecteur aérodynamique 38 qui est agencé le long du bord inférieur 40 du boîtier 22, et dont la forme est conçue pour qu'il dévie au moins en partie les turbulences pour les diriger en arrière du véhicule 12, comme on l'a représenté par la flèche F.For this purpose, as can be seen in FIG. 2, the housing 22 includes an aerodynamic deflector 38 which is arranged along the lower edge 40 of the housing 22, and whose shape is designed so that it deflects at least in part the turbulence to direct them behind the vehicle 12, as shown by the arrow F.
On a décrit un dispositif de détection 10 pour lequel les faces interne 26i et externe 26e de la fenêtre 26 sont recouvertes par un même revêtement. Cependant, il sera compris que l'invention n'est pas limitée à ce mode de réalisation, et que chaque face de la fenêtre peut être recouverte d'un revêtement ayant les propriétés de nettoyage adéquat, sans sortir du domaine de l'invention. Un dispositif de détection conforme à l'invention comporte plusieurs moyens de nettoyage des fenêtres qui permettent de conserver celles-ci exemptes de tout élément polluant pouvant nuire à l'efficacité des moyens de détection. A detection device 10 has been described for which the internal 26i and external 26e faces of the window 26 are covered by the same coating. However, it will be understood that the invention is not limited to this embodiment, and that each face of the window can be covered with a coating having adequate cleaning properties, without departing from the scope of the invention. A detection device according to the invention comprises several means for cleaning the windows which make it possible to keep them free from any polluting element which could harm the effectiveness of the detection means.
