Description

La présente invention concerne un véhicule de transport public, notamment un véhicule ferroviaire, et plus particulièrement un véhicule ferroviaire urbain tel qu'un tramway.The present invention relates to a public transport vehicle, in particular a railway vehicle, and more particularly an urban railway vehicle such as a tramway.

Un véhicule de transport public comporte une zone passagers destinée à accueillir des passagers, délimitée par des parois, notamment des parois latérales et un pavillon.A public transport vehicle includes a passenger area intended to accommodate passengers, delimited by walls, in particular side walls and a roof.

Afin que les passagers présents dans la zone passagers puissent apprécier un paysage urbain, on connait déjà, dans l'état de la technique, des véhicules de transport, notamment des bus, équipés d'un pavillon dit « panoramique », c'est-à-dire un pavillon transparent au travers duquel les passagers peuvent observer le paysage au-dessus du véhicule. On connait également des véhicules de transport comportant un pavillon ouvrant ou ouvert, pour un même effet.So that passengers present in the passenger area can appreciate an urban landscape, we already know, in the state of the art, transport vehicles, in particular buses, equipped with a so-called “panoramic” roof, i.e. i.e. a transparent roof through which passengers can observe the landscape above the vehicle. We also know transport vehicles with an opening or open roof, for the same effect.

Toutefois, un tel pavillon panoramique n'est pas adapté à un véhicule ferroviaire urbain. En effet, un véhicule ferroviaire urbain comporte généralement divers équipement électroniques, comprenant notamment des pantographes, agencés sur le pavillon de ce véhicule.However, such a panoramic pavilion is not suitable for an urban rail vehicle. Indeed, an urban rail vehicle generally includes various electronic equipment, including in particular pantographs, arranged on the roof of this vehicle.

Ces équipements électroniques ne permettent pas de ménager une ouverture suffisante pour permettre aux passagers d'observer le paysage au-dessus du véhicule.This electronic equipment does not provide a sufficient opening to allow passengers to observe the landscape above the vehicle.

On connait également, d'après EP 2 628 649 , un véhicule ferroviaire similaire à celui du préambule de la revendication 1.We also know, according to EP 2 628 649 , a railway vehicle similar to that of the preamble of claim 1.

L'invention a notamment pour but de remédier à l'inconvénient précité, en proposant un véhicule de transport public ferroviaire urbain, permettant aux passagers d'observer le paysage urbain, notamment au-dessus du véhicule.The invention aims in particular to remedy the aforementioned drawback, by proposing an urban rail public transport vehicle, allowing passengers to observe the urban landscape, in particular above the vehicle.

A cet effet, l'invention a notamment pour objet un véhicule de transport public ferroviaire urbain selon la revendication 1.To this end, the subject of the invention is in particular an urban rail public transport vehicle according to claim 1.

En retranscrivant les images capturées en temps réel sur le dispositif d'affichage, les passagers observent indirectement le paysage au-delà de cette paroi, notamment de ce pavillon.By transcribing the images captured in real time on the display device, passengers indirectly observe the landscape beyond this wall, in particular this pavilion.

Cette invention est particulièrement adaptée à un véhicule ferroviaire urbain, notamment à un tramway, car elle permet aux passagers d'observer le paysage au-dessus du véhicule malgré la présence d'équipements électroniques sur le pavillon.This invention is particularly suitable for an urban rail vehicle, in particular a tramway, because it allows passengers to observe the landscape above the vehicle despite the presence of electronic equipment on the roof.

Un véhicule selon l'invention peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises seules ou selon toutes combinaisons techniquement envisageables.

  • Chaque dispositif d'affichage comporte une dalle présentant une surface d'affichage orientée vers la zone passagers, au moins l'un des dispositifs de capture d'images étant agencé en arrière de la dalle, les moyens de liaison et de traitement reliant ce dispositif de capture d'images avec cette dalle de sorte que les images affichées par cette dalle sont des images capturées en arrière de cette dalle.
  • Le système d'affichage comporte une pluralité de dispositifs d'affichage, dont les dalles sont alignées pour recouvrir une partie ou l'intégralité de la surface intérieure de la paroi correspondante.
  • Au moins deux dalles adjacentes sont accolées de manière coplanaires, de sorte que ces dalles adjacentes présentent ensemble une surface d'affichage commune continue ou quasi-continue.
  • Le système d'affichage comporte une pluralité de dispositifs de capture d'images, alignés sur la surface extérieure de la paroi correspondante, présentant chacun un champ de vision, agencés de sorte que les champs de vision des dispositifs de capture d'images de chaque paire de deux dispositifs de capture d'images adjacents présentent une zone commune.
  • Les moyens de liaison et de traitement comportent des moyens de compilation des images capturées par la pluralité de dispositifs de capture d'image, propres à compiler les images capturées par les dispositifs de capture d'images en une image collective, dans laquelle les images capturées par deux dispositifs de capture d'images adjacents sont alignées avec un recouvrement correspondant à la zone commune de leurs champs de vision.
  • Les moyens de liaison et de traitement comportent des moyens de séparation de l'image collective, propre à séparer l'image collective en une pluralité de sous-images, chacune affichée par l'un respectif des dispositifs d'affichage.
  • Chaque dispositif d'affichage est propre à afficher des images d'information et/ou des images décoratives, par superposition aux images capturées, ou alternativement à ces images capturées.
A vehicle according to the invention may also include one or more of the following characteristics, taken alone or in any technically conceivable combination.
  • Each display device comprises a panel having a display surface oriented towards the passenger area, at least one of the image capture devices being arranged behind the panel, the connection and processing means connecting this device capturing images with this panel so that the images displayed by this panel are images captured behind this panel.
  • The display system includes a plurality of display devices, the tiles of which are aligned to cover part or all of the interior surface of the corresponding wall.
  • At least two adjacent tiles are joined together in a coplanar manner, so that these adjacent tiles together present a continuous or quasi-continuous common display surface.
  • The display system comprises a plurality of image capture devices, aligned on the exterior surface of the corresponding wall, each having a field of vision, arranged so that the fields of vision of the image capture devices of each pair of two adjacent image capture devices have a common area.
  • The linking and processing means comprise means for compiling the images captured by the plurality of image capture devices, capable of compiling the images captured by the image capture devices into a collective image, in which the captured images by two adjacent image capture devices are aligned with an overlap corresponding to the common area of their fields of vision.
  • The connection and processing means comprise means for separating the collective image, capable of separating the collective image into a plurality of sub-images, each displayed by a respective display device.
  • Each display device is capable of displaying information images and/or decorative images, by superposition on the captured images, or alternatively on these captured images.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux figures annexées, parmi lesquelles :

  • la figure 1 est une vue partielle du dessus d'un véhicule de transport public selon un exemple de mode de réalisation de l'invention,
  • la figure 2 est une vue partielle de profil du véhicule de la figure 1 ;
  • la figure 3 est une vue partielle schématique d'une surface intérieure d'un pavillon du véhicule de la figure 1.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, among which:
  • there figure 1 is a partial top view of a public transport vehicle according to an example embodiment of the invention,
  • there figure 2 is a partial profile view of the vehicle of the figure 1 ;
  • there Figure 3 is a schematic partial view of a interior surface of a roof of the vehicle of the figure 1 .

On a représenté partiellement sur la figure 1 un véhicule de transport public, notamment un tramway 10.We have partially represented on the figure 1 a public transport vehicle, in particular a tramway 10.

Le véhicule de transport 10 comporte au moins une cabine de conduite 12 de type classique, assemblée avec au moins une caisse structurelle 15 classique. Plus particulièrement, le véhicule de transport 10 comporte une pluralité de caisses structurelles 15 alignées le long d'une direction longitudinale X entre deux cabines de conduite 12 (dont une seule est représentée). Chaque caisse 15 est séparée d'au moins une caisse adjacente par un dispositif d'intercirculation 16 de type classique.The transport vehicle 10 comprises at least one classic type driving cabin 12, assembled with at least one classic structural body 15. More particularly, the transport vehicle 10 comprises a plurality of structural bodies 15 aligned along a longitudinal direction X between two driving cabins 12 (only one of which is shown). Each box 15 is separated from at least one adjacent box by an intercirculation device 16 of conventional type.

Chaque caisse 15 comporte des parois, notamment des parois latérales 18 et un pavillon 20. Les parois 18, 20 de chaque caisse 15 délimitent entre elles une zone passagers 14 respective, destinée à accueillir des passagers.Each box 15 has walls, in particular side walls 18 and a roof 20. The walls 18, 20 of each box 15 delimit between them a respective passenger zone 14, intended to accommodate passengers.

Chacune de ces parois 18, 20 présente une surface intérieure tournée vers la zone passagers 14 et une surface extérieure tournée vers l'extérieur du véhicule 10.Each of these walls 18, 20 has an interior surface facing the passenger area 14 and an exterior surface facing the exterior of the vehicle 10.

Plus particulièrement, la surface intérieure du pavillon 20 est désignée par la référence 20A, représentée sur la figure 3, et la surface extérieure du pavillon 20 est désignée par la référence 20B, représentée sur la figure 1.More particularly, the interior surface of the pavilion 20 is designated by the reference 20A, shown on the Figure 3 , and the exterior surface of the pavilion 20 is designated by the reference 20B, shown on the figure 1 .

Le véhicule 10 selon l'invention comporte un système d'affichage 22, comprenant au moins un dispositif d'affichage 24 logé dans au moins l'une des zones passagers 14, de préférence dans chaque zone passagers 14.The vehicle 10 according to the invention comprises a display system 22, comprising at least one display device 24 housed in at least one of the passenger zones 14, preferably in each passenger zone 14.

Chaque dispositif d'affichage 24 comporte une dalle 26 présentant une surface d'affichage 28. Chaque dalle 26 est agencée sur la surface intérieure d'une paroi 18, 20, sa surface d'affichage 28 étant orientée vers la zone passagers 14 correspondante.Each display device 24 comprises a panel 26 having a display surface 28. Each panel 26 is arranged on the interior surface of a wall 18, 20, its display surface 28 being oriented towards the corresponding passenger area 14.

Dans l'exemple décrit, les dalles 26 sont agencées sur la surface intérieure 20A du pavillon 20 de chaque caisse 15, comme cela est représenté sur la figure 3.In the example described, the slabs 26 are arranged on the interior surface 20A of the roof 20 of each box 15, as shown in the figure. Figure 3 .

Plus particulièrement, le système d'affichage 22 comporte, pour chaque zone passagers 14, une pluralité de dispositif d'affichage 24 dont les dalles 26 sont alignées le long de la direction longitudinale X, en recouvrant une partie ou l'intégralité de la surface intérieure 20A du pavillon 20 correspondant. De préférence, les dalles 26 sont alignées pour recouvrir l'intégralité de la surface intérieure 20A du pavillon 20 de chaque caisse 15. Les dalles 26 de deux caisses 15 adjacentes sont donc séparées par une partie supérieure du dispositif d'intercirculation 16 insérée entre ces caisses 15. Cette partie supérieure du dispositif d'intercirculation 16 peut comporter un dispositif d'affichage, ou en variante être exempt de dispositif d'affichage.More particularly, the display system 22 comprises, for each passenger zone 14, a plurality of display devices 24 whose tiles 26 are aligned along the longitudinal direction interior 20A of the corresponding pavilion 20. Preferably, the slabs 26 are aligned to cover the entire interior surface 20A of the roof 20 of each box 15. The slabs 26 of two adjacent boxes 15 are therefore separated by an upper part of the intercirculation device 16 inserted between these crates 15. This upper part of the intercirculation device 16 may include a display device, or alternatively be free of a display device.

Avantageusement, comme cela est représenté sur la figure 3, une pluralité de dalles adjacentes 26 sont accolées de manière coplanaire, de sorte que ces dalles adjacentes 26 présentent ensemble une surface d'affichage commune continue ou quasi-continue. Par « quasi-continue », on entend que les deux dalles 26 sont séparées par un espacement très faible, notamment inférieur à 10 mm.Advantageously, as shown in the Figure 3 , a plurality of adjacent tiles 26 are joined together in a coplanar manner, so that these adjacent tiles 26 together present a common continuous or quasi-continuous display surface. By “quasi-continuous” we mean that the two slabs 26 are separated by a very small spacing, in particular less than 10 mm.

Le système d'affichage 22 comporte par ailleurs au moins un dispositif de capture d'images 30, agencé sur la surface extérieure de l'une des parois 18, 20. Plus particulièrement, le système d'affichage 22 comporte un dispositif de capture 30 pour chaque dispositif d'affichage 24, agencé à proximité de ce dispositif d'affichage 24. Ainsi, chaque dispositif de capture 30 est agencé sur la surface extérieure de l'une des parois 18, 20 portant un dispositif d'affichage qui lui est lié sur sa surface intérieure.The display system 22 furthermore comprises at least one image capture device 30, arranged on the exterior surface of one of the walls 18, 20. More particularly, the display system 22 comprises a capture device 30 for each display device 24, arranged near this display device 24. Thus, each capture device 30 is arranged on the exterior surface of one of the walls 18, 20 carrying a display device which is attached to it bound on its interior surface.

Dans l'exemple décrit, au moins un dispositif de capture d'images 30 est agencé sur la surface extérieure 20B du pavillon 20, et orienté pour capturer les images d'un environnement dans lequel évolue le véhicule de transport 10. Plus particulièrement, chaque dispositif de capture d'images 30 est avantageusement orienté vers le haut.In the example described, at least one image capture device 30 is arranged on the exterior surface 20B of the roof 20, and oriented to capture images of an environment in which the transport vehicle 10 operates. More particularly, each image capture device 30 is advantageously oriented upwards.

Chaque dispositif d'affichage 24 est relié à au moins l'un de ces dispositifs de capture d'images 30 par des moyens de liaison et de traitement informatiques (non représentés), de sorte que chaque dispositif d'affichage 24 est propre à afficher des images capturées par au moins l'un des dispositifs de capture d'images 30 agencé à proximité de ce dispositif d'affichage 24.Each display device 24 is connected to at least one of these image capture devices 30 by computer connection and processing means (not shown), so that each display device 24 is capable of displaying images captured by at least one of the image capture devices 30 arranged near this display device 24.

Avantageusement, chaque dispositif de capture d'images 30 est agencé en arrière d'une dalle 26 correspondante, de sorte que les images affichées par cette dalle 26 sont des images capturées en arrière de cette dalle 26.Advantageously, each image capture device 30 is arranged behind a corresponding panel 26, so that the images displayed by this panel 26 are images captured behind this panel 26.

Conformément au mode de réalisation décrit, le système d'affichage 22 comporte une pluralité de dispositifs de capture d'images 30, alignés le long de la direction longitudinale X sur la surface extérieure 20B du pavillon 20.In accordance with the embodiment described, the display system 22 comprises a plurality of image capture devices 30, aligned along the longitudinal direction X on the exterior surface 20B of the roof 20.

Chacun de ces dispositifs de capture d'images 30 présente un champ de vision 32, représenté sur la figure 1 par un cercle centré sur ce dispositif de capture d'images 30, et sur la figure 2 par un cône également centré sur ce dispositif de capture d'images 30.Each of these image capture devices 30 has a field of vision 32, shown on the figure 1 by a circle centered on this image capture device 30, and on the figure 2 by a cone also centered on this image capture device 30.

Il est à noter que les dispositifs de capture d'images 30 sont agencés de sorte que chaque paire de deux dispositifs de capture d'images 30 adjacents ont leurs champs de vision 32 qui se recoupent, présentant ainsi une zone commune 34.It should be noted that the image capture devices 30 are arranged so that each pair of two adjacent image capture devices 30 have their fields of vision 32 which overlap, thus presenting a common area 34.

Ainsi, les images capturées par deux dispositifs de capture d'images 30 adjacents présentent des parties identiques, correspondants à la zone commune 34 de leurs champs de vision 32.Thus, the images captured by two adjacent image capture devices 30 have identical parts, corresponding to the common area 34 of their fields of vision 32.

Lesdits moyens de liaison et de traitement comportent des moyens de compilation des images capturées par la pluralité de dispositifs de capture d'images 30, propres à compiler les images capturées par ces dispositifs de capture d'images 30 en une image collective. Cette image collective est formée par les images capturées par les dispositifs de capture d'images 30, alignées en recouvrant les parties d'images identiques.Said linking and processing means comprise means for compiling the images captured by the plurality of image capture devices 30, capable of compiling the images captured by these image capture devices 30 into a collective image. This collective image is formed by the images captured by the image capture devices 30, aligned by covering the parts of identical images.

Dans l'image collective, ces images capturées par deux dispositifs de capture d'images adjacents sont donc alignés avec un recouvrement de leurs parties identiques correspondant à leur zone commune 34.In the collective image, these images captured by two adjacent image capture devices are therefore aligned with an overlap of their identical parts corresponding to their common zone 34.

On obtient ainsi une image collective continue dans chaque zone passagers 14.We thus obtain a continuous collective image in each passenger area 14.

Les moyens de liaison et de traitement comportent également des moyens de séparation de l'image collective, propre à séparer cette image collective en une pluralité de sous-images, chacune étant affichée par l'un respectif des dispositifs d'affichage 24. Ceci permet de restituer l'image collective sur l'intégralité des dispositifs d'affichage 24, cette image collective étant restituée de manière continue.The connection and processing means also include means for separating the collective image, capable of separating this collective image into a plurality of sub-images, each being displayed by a respective one of the display devices 24. This allows to restore the collective image on all of the display devices 24, this collective image being restored continuously.

Chaque dispositif d'affichage 24 et chaque dispositif de capture 30 présente de préférence une haute résolution. Ainsi, les images restituées sur les dispositifs d'affichage 24 sont sensiblement d'aussi bonne qualité que si les passagers observaient le paysage au travers d'un pavillon panoramique de l'état de la technique.Each display device 24 and each capture device 30 preferably has a high resolution. Thus, the images rendered on the display devices 24 are of substantially as good quality as if the passengers were observing the landscape through a state-of-the-art panoramic pavilion.

Par ailleurs, les moyens de liaison et de traitement permettent une restitution des images en temps réel, de sorte que les images restituées sur les dispositifs d'affichage 24 correspondent en temps réel au paysage de l'environnement dans lequel le véhicule 10 évolue.Furthermore, the connection and processing means allow images to be reproduced in real time, so that the images reproduced on the display devices 24 correspond in real time to the landscape of the environment in which the vehicle 10 operates.

Avantageusement, chaque dispositif d'affichage 24 est propre à afficher des images d'informations et/ou des images décoratives, notamment par superposition avec l'image collective restituée, ou alternativement à cette image collective. Ceci permet d'ajouter des informations, notamment relatives au paysage visible, sur l'image collective restituée, à afficher des publicités, ou à afficher tout autre élément décoratif. Ces images d'information et/ou décoratives sont par exemple affichées par le dispositif d'affichage 24 en remplacement de l'image collective lorsque le véhicule 10 passe dans un tunnel, ou lorsque cela est souhaité par un opérateur.Advantageously, each display device 24 is capable of displaying information images and/or decorative images, in particular by superposition with the restored collective image, or alternatively with this collective image. This makes it possible to add information, in particular relating to the visible landscape, to the restored collective image, to display advertisements, or to display any other decorative element. These information and/or decorative images are for example displayed by the display device 24 replacing the collective image when the vehicle 10 passes through a tunnel, or when this is desired by an operator.

En variante, le système d'affichage 22 comprend des moyens de détection de conditions environnementales, propres à afficher automatiquement des images d'informations et/ou des images décoratives en remplacement de l'image collective, en fonction de paramètres détectés de conditions environnementales.Alternatively, the display system 22 comprises means for detecting environmental conditions, capable of automatically displaying information images and/or decorative images in replacement of the collective image, depending on detected parameters of environmental conditions.

Avantageusement, les moyens de détection de conditions environnementales comprennent des capteurs de luminosité extérieure, et sont propres à afficher automatiquement des images d'informations et/ou des images décoratives, lorsque la luminosité extérieure détectée est inférieure à un seuil prédéterminé.Advantageously, the means for detecting environmental conditions include external brightness sensors, and are capable of automatically displaying information images and/or decorative images, when the detected external brightness is less than a predetermined threshold.

Avantageusement, les moyens de détection de conditions environnementales comprennent des capteurs de pluie et/ou de neige, et sont propres à afficher automatiquement des images d'informations et/ou des images décoratives, lorsque la quantité pluie et/ou de neige extérieure détectée est supérieure à un seuil prédéterminé.Advantageously, the means for detecting environmental conditions include rain and/or snow sensors, and are capable of automatically displaying information images and/or decorative images, when the quantity of detected exterior rain and/or snow is greater than a predetermined threshold.

Ainsi, ces moyens de détection environnementale permettent d'éviter un affichage d'images du paysage de mauvaise qualité, lorsque les conditions environnementales sont dégradées.Thus, these environmental detection means make it possible to avoid displaying poor quality landscape images, when environmental conditions are degraded.

Avantageusement, chaque dispositif de capture d'images 30 comporte un mode de capture d'images de nuit, par exemple un mode infrarouge. Ainsi, les dispositifs d'affichage 24 sont propres à afficher une représentation du paysage, même de nuit.Advantageously, each image capture device 30 includes a night image capture mode, for example an infrared mode. Thus, the display devices 24 are capable of displaying a representation of the landscape, even at night.

L'invention n'est pas limitée au mode de réalisation précédemment décrit, mais pouvait présenter diverses variantes.The invention is not limited to the embodiment described above, but could present various variants.

Par exemple, alors que les parois latérales 18 d'un véhicule ferroviaire comportent habituellement des fenêtres, au moins certaines de ces fenêtres pourraient être remplacées par des dispositifs d'affichage 24 tels que décrits précédemment. Ces dispositifs d'affichage 24 sont alors reliés à des dispositifs de capture d'images comme décrits précédemment.For example, while the side walls 18 of a railway vehicle usually include windows, at least some of these windows could be replaced by display devices 24 as described above. These display devices 24 are then connected to image capture devices as described previously.

Ceci a notamment pour intérêt de permettre l'affichage d'images d'informations et/ou d'images décoratives par superposition aux images capturées, comme indiqué précédemment, ce qui n'est pas possible pour des fenêtres classiques.This has the particular advantage of allowing the display of information images and/or decorative images by superposition on the captured images, as indicated previously, which is not possible for conventional windows.

Afin, il est à noter que, bien que l'invention soit particulièrement adaptée à un véhicule ferroviaire, il peut être adapté à tout autre véhicule de transport public, notamment à des bus ou autocars.Therefore, it should be noted that, although the invention is particularly adapted to a railway vehicle, it can be adapted to any other public transport vehicle, in particular to buses or coaches.
