    [0001] DEVICE FOR DISPLAYING AT LEAST ONE PICTOGRAM WITHIN A VEHICLE. The present invention relates to the field of information display devices within a vehicle passenger compartment, as well as to the field of vehicle equipment control devices comprising such a display device. More particularly, the invention relates to a device for displaying at least one pictogram inside a vehicle cabin, comprising: a light source connected to a control system and adapted to emit a light in response to a control signal, and; An opaque covering layer having a certain hue and comprising a through opening defining said pictogram. Pictogram means here a symbol, a character or a set of characters intended to be displayed inside the passenger compartment of a vehicle in order to indicate to an occupant information relating to a vehicle equipment. Such a display device may for example be located at the dashboard of the vehicle 25 to indicate to the occupants an operating zone and / or information relating to an operating state of a vehicle equipment such as an air-conditioning system, a parking brake system, a de-icing device, etc. Conventionally, in display devices of this type, the through opening made in the cladding layer and defining the pictogram intended for to be displayed to the occupants of the vehicle, is filled or covered by a transparent or translucent element for example reported by gluing or co-injected with the covering layer. Such a light-permeable element makes it possible to close or cover the opening formed in the covering layer in order to prevent impurities originating from the passenger compartment of the vehicle from penetrating inside the display device, and so that the display device has an outer surface visible by the occupants of the vehicle which is smooth, that is to say without relief. Nevertheless, such a conventional pictogram display device has the particular disadvantage that, even when the light source is deactivated and does not emit light towards the covering layer, the pictogram or pictograms provided thereon are visible to the occupants of the vehicle, which affects the overall aesthetics of the display device and / or the dashboard on which it is arranged. Indeed, on the one hand, the light permeable elements obstructing the openings of the covering layer and this opaque covering layer being made of different materials, at least in terms of permeability to light, the pictograms defined these openings are visible by reflecting the ambient light inside the passenger compartment for an occupant of the vehicle even when the light source is inactive.
    [0002] On the other hand, the elements obstructing or covering the openings of the covering layer are made of a material that is permeable to light permanently, whether the light source is activated or not. Therefore, even when the light source is inactive, the ambient light inside the passenger compartment of the vehicle can pass through these elements, reflect on components located behind and return to the passenger compartment after crossing at again these elements obstructing or covering the openings, and thus be visible to the occupants of the vehicle.
    [0003] The document FR2825832 describes an exemplary display device implemented within a touch control device of vehicle equipment that provides a solution to the problem mentioned above. In the display device according to this document, the light source is constituted by an electroluminescent film, arranged behind a covering layer made of opaque plastic material and through which were made various cuts of various shapes that can represent a button, a slider, etc .... Such a device has the advantage that, when the electroluminescent film is not active, that is to say when it emits no light, the pictograms defined by the cuts made in the covering layer are not or not very visible for an occupant of the vehicle. In fact, the electroluminescent film in the inactive state forms an opaque layer which, by presenting the same shade as the covering layer, makes it possible to make the pictograms invisible to an occupant of the vehicle.
    [0004] However, to achieve this objective, the device according to this document FR2825832 implements an electroluminescent film as a light source, which has the major disadvantage of being a particularly expensive solution.
    [0005] Moreover, the use of such electroluminescent films as a light source imposes, in particular for cost limitation reasons, to group / centralize the various pictograms intended to be displayed to the occupants of the vehicle, for example in a circumscribed area of the dashboard, which affects the freedom of design and design thereof. The present invention is intended to overcome these disadvantages.
    [0006] For this purpose, according to the invention, a display device of the aforementioned type is characterized in that it further comprises a photosensitive layer having an inner face facing the light source and an outer face opposite the face. interior and facing the passenger compartment of the vehicle, and extending facing and / or in said opening, and in that, when said light source is deactivated, said photosensitive layer is opaque and has the same shade as the 10 covering layer and, when said light source is activated, said photosensitive layer reacts so as to make visible the pictogram defined by the opening of the covering layer for an occupant of the passenger compartment of the vehicle. By "reacting" is meant here that the photosensitive layer changes intrinsic optical properties depending on whether the rearward light source is active or inactive, i.e., whether or not it emits light. This change may be reflected in terms of light permeability, the photosensitive layer being adapted to pass at least partially the light emitted by the light source through the opening of the covering layer when this light source is active. Thus, the photosensitive layer according to the invention has a first optical state, in which it is opaque, that is to say totally impermeable to light, and in particular to the ambient light prevailing inside the the interior of the vehicle, and has the same hue as the covering layer when the light source is inactive, and a second optical state, in which it is at least partially permeable to light, and in particular to light from the light source when it is active. The change in intrinsic optical properties of the photosensitive layer subsequent to the activation of the light source may also be reflected in terms of hue, the photosensitive layer being adapted to change hue when that light source is active. Thus, the photosensitive layer according to the invention has a first optical state, in which it is opaque, that is to say totally impermeable to light, and in particular to the ambient light prevailing inside the passenger compartment. of the vehicle, and has the same shade as the covering layer when the light source is inactive, and a second optical state, it remains substantially opaque but has a different shade of the skin layer when the light source is active . Thanks to these provisions, the invention proposes an inexpensive display device to achieve, which can be implemented in various discrete areas of the vehicle, and in particular the dashboard, and to make the pictograms invisible to the occupants of the vehicle as long as the light source is not activated.
    [0007] Advantageously, the light source may consist of a conventional light bulb or a light emitting diode (LED) which has the particular advantage of having a low cost.
    [0008] In preferred embodiments of the invention, one or more of the following provisions may also be used: the covering layer is formed of an opaque paint layer; the photosensitive layer is formed of a layer of photosensitive paint; the photosensitive layer reacts beyond an illumination threshold by the light source, said threshold being greater than the average illumination of a vehicle passenger compartment. In general, especially in the case of a closed passenger vehicle (undiscovered) traveling during a day of average sunshine, the ambient light prevailing inside a vehicle interior and received by the various elements located in this cabin and on which can be arranged a display device according to the invention, such as a dashboard, a central console, a central rearview mirror, etc ...., does not exceed average a certain value hereinafter referred to as average illumination. Thus, by fixing an illumination threshold beyond which the photosensitive layer reacts higher than the average illumination of a vehicle passenger compartment, the ambient light inside the passenger compartment is prevented from causing the photosensitive layer to react. and reveals the pictograms defined by the openings made in the covering layer. In other words, thanks to these provisions, it is ensured that, in general, only the light source can emit a sufficiently intense / powerful light to react the photosensitive layer and make it pass from a state of opacity at least a partial state of transparency or change the color. the light source is adapted to emit light in a wavelength range at which the photosensitive layer reacts and the display device further comprises a filter located on the side of the outer face of the photosensitive layer and adapted to block at least the wavelength range at which the photosensitive layer reacts from the passenger compartment of the vehicle. The light source is adapted to emit light located at least in part in said wavelength range. Thanks to these arrangements, the portion of the light coming from the passenger compartment of the vehicle which has wavelengths at which the photosensitive layer is sensitive / reacts, is blocked by the filter and does not reach the photosensitive layer. This ensures that only the light source, when activated, is able to react the photosensitive layer. the covering layer is attached to the photosensitive layer acts as a mask of the photosensitive layer out of the areas to be displayed and defines with said photosensitive layer a cavity at the opening, and the display device further comprises a at least partially transparent coating layer covering said covering layer and filling said cavity. Thanks to these arrangements, the outer surface of the display device, visible to the occupants of the vehicle, appears perfectly smooth and uniform, both visually and to the touch, the layer of varnish added to the covering layer eliminating the relief present on it consisting of the opening defining the pictogram to be displayed. the covering layer is attached to the photosensitive layer and defines with said photosensitive layer a cavity at the opening, and the display device further comprises a layer of at least partially transparent varnish covering said covering layer; filling said cavity and constituting the filter. In this embodiment, the varnish added to the covering layer serves as a filter for blocking the wavelengths of light from the passenger compartment and to which the photosensitive layer reacts. the light source is adapted to emit light comprising light waves located in a given plane to which the photosensitive layer reacts and the display device further comprises a polarizing film located on the side of the outer face of the photosensitive layer of so that the light from the passenger compartment of the vehicle and polarized by passing through said film is polarized in such a way that it does not react the photosensitive layer. In this embodiment, the light from the passenger compartment is transformed before it reaches the photosensitive layer, by passing through the polarizing film, so that this transformed light can not react the photosensitive layer. Thus, in this embodiment, it could be provided that the photosensitive layer is sensitive / reactive only to light waves located in a given plane; in this case, the polarizing film will be designed so as to polarize the light waves from the passenger compartment of the vehicle in a plane different from the plane mentioned above. In this way, it prevents the photosensitive layer is reached by light waves to which it reacts from the passenger compartment of the vehicle. the light source is a first light source and the display device further comprises a second light source connected to the control system and adapted to emit light in response to a second control signal following the activation of the first light source, the inner face of the photosensitive layer facing the first and second light sources. The various technical solutions envisaged to ensure that only the source of light placed behind is able to react the photosensitive layer and change it from a state of opacity to an at least partial state of transparency or to make it change hue, namely the definition of an illumination threshold beyond which the photosensitive layer reacts, the implementation of a filter or a polarizing film, can be implemented in the display device according to the invention cumulatively or alternatively without departing from the scope of the present invention. The present invention furthermore relates to a control device of a vehicle equipment comprising a display device as described above and a support detection sensor. According to a particularly advantageous arrangement, the support detection sensor is formed of a capacitive film. Finally, the invention also relates to a vehicle dashboard comprising a display device and / or a control device as described above.
    [0009] Other features and advantages of the invention will become apparent from the following description of one of its embodiments, given by way of non-limiting example, with reference to the accompanying drawings. In the drawings: - Figure 1 is a partial perspective view showing the front portion of a vehicle interior comprising a dashboard on which is implemented a control device comprising a display device according to the invention; - Figure 2 shows a sectional view along the line II-II of Figure 1 to illustrate the structure of a control device according to the invention implanted at the dashboard of the vehicle; FIG. 3 represents on an enlarged scale the zone marked A in FIG. 2 and intended to illustrate the stack of layers used in a control device according to the invention. In the different figures, the same references designate identical or similar elements. FIG. 1 partially shows in perspective a front portion of a passenger compartment 100 comprising a dashboard 110 on which a control device 11 of a vehicle equipment comprising a display device 1 is provided. according to the invention. In this figure 1, and for purposes of simplification of the following description, the dashboard 110 illustrated has only one control device 11 provided, when actuated, to control the ignition and / or extinguishing the vehicle's hazard lights. Thus, in the exemplary embodiment illustrated in this FIG. 1, the display device 1 according to the invention, implemented in this control device 11 of the hazard warning lights, makes it possible, when activated, to display the occupants of the vehicle a triangular pictogram delimiting the area on which the occupants of the vehicle must act to cause the hazard warning lights to come on or off and illustrated in fine lines in Figure 1. However, the device 1 display according to the invention may be used to display other pictograms representative of the operating zone and / or the operating status of other equipment of the vehicle, such as an air conditioning system, a brake system parking, a deicing device, etc ..., or be implemented in a control device 11 of such equipment without departing from the scope of the present invention. FIG. 2 is a sectional view along the line II-II of FIG. 1 of the structure of a control device 11 implementing a pictogram display device 1 according to the invention. In this FIG. 2, it can be seen that the control device 11 according to the invention is here implanted at the level of the dashboard of the vehicle 110 and integrated therewith, and fixed at the level of a support 13 forming part of the vehicle. or being secured to the vehicle structure. The hazard warning control device 11 illustrated in this FIG. 2 comprises a display device 1 of the triangular pictogram representative of the operating zone and of the operating state of the hazard warning lights, as well as a sensor of FIG. support detection 6 adapted to detect a support and / or pressure exerted by a vehicle occupant wishing to activate or deactivate the vehicle hazard warning lights.
    [0010] In the exemplary embodiment illustrated in FIGS. 2 and 3, the support detection sensor consists of a capacitive film 6 making it possible to detect the contact of a finger of an occupant of the vehicle on the operating zone. the outer surface of the dashboard 110 to which the control device 11 of the hazard lights is associated. It could however be envisaged without departing from the scope of the present invention that the support detection sensor is formed by a resistive film, or more conventionally that the vehicle equipment control device 11 according to the invention is presented under the shape of a movable button whose actuation is detected by a button position sensor. Still with reference to this FIG. 2, the control device 11 for the hazard warning lights comprises a display device 1 of the triangular pictogram representative of the operating zone and the operating state of the hazard warning lights, which comprises a source of warning lights. light 2 connected to a control system 9, here an electronic control board, and adapted to emit light in response to a control signal from the control system 9. In the embodiment illustrated in Figures 2 and 3, the display device 1 is included in a vehicle equipment control device 11 implementing a support detection sensor 6. Thus, in this embodiment, the signal controlling the activation of the light source 2 of the display device 1 is generated by the control system 9 for example following the power of the dashboard, in particular during the ignition of the vehicle. Furthermore, following the detection of a support by a vehicle occupant on the equipment control device 11 by the support detection sensor 6, the control system 9 generates a signal causing the activation or deactivation equipment controlled by the equipment control device 11, in this case the hazard lights, and is adapted to generate a control signal to the light source 2 controlling its activation for example in flashing mode for represent the active state of the hazard warning lights or its activation in continuous mode to represent the inactive state of the hazard warning lights, leaving the pictogram visible to the occupants of the vehicle and thus continue to delimit the zone of activation of the hazard warning lights as long as the dashboard is on. The light source 2 implemented in the display device 1 according to the invention may for example consist of a light emitting diode, which has among other advantages low power consumption, reduced size and a low cost. In the exemplary embodiment illustrated in FIG. 2, this light source 2 is associated with a light box 12 making it possible to guide the light emitted by the source towards the area to be illuminated. Furthermore, the pictogram display device 1 according to the invention comprises a stack of layers 8 comprising an opaque covering layer 30 having a certain hue and in which is formed a through opening 32 which defines the pictogram to be displayed. More precisely, and as can be seen in FIG. 3, the covering layer 3 has an inner face 35 located on the side of the light source 2 and an outer face 31 opposite the inner face 30 and located on the side of the light source. the passenger compartment of the vehicle, and the opening 32 defining the pictogram to be displayed and visible in fine lines in Figure 1 extends from the inner face 30 to the outer face 31 of the covering layer 3. In the illustrated embodiment in FIGS. 2 and 3, the layer stack 8 comprises a dashboard control panel insert 7, made for example of a plastic material, in particular a translucent material, and forms part of the outer surface of the dashboard 110 visible to the occupants of the vehicle. In FIG. 3, the layer stack 8 further comprises a photosensitive layer 4 having an inner face 40 located on the side of the light source 2 and an outer face 41 opposite the inner face 40 and located on the side of the light source. cabin of the vehicle. This photosensitive layer 4 also extends opposite the opening 32 formed in the covering layer 3, as can be seen in FIG. 3. Alternatively or in combination, it would be possible for the photosensitive layer 4 to extend into the opening 32 of the covering layer 3. In this case, it would be advantageous to provide that the covering layer 3 and the photosensitive layer 4 are produced jointly for example by a co-injection technique of plastics or by a overmolding technique. In the exemplary embodiment illustrated in the figures, the covering layer 3 is formed of an opaque paint layer conventionally used to cover vehicle elements such as a dashboard, and the photosensitive layer 4 is formed of a layer of photosensitive paint. According to the invention, the photosensitive layer 4 is provided to be opaque by having the same shade as the covering layer 3 when the light source 2 emits no light. In other words, when the light source is deactivated, the covering layer 3 and the photosensitive layer 4 are both opaque with the same hue. Thus, the opening 32 formed in the covering layer 3 and defining the pictogram to be displayed is masked by the photosensitive layer 4 and is not visible, is not distinguishable for an occupant of the vehicle. On the other hand, the photosensitive layer 4 is designed to react with the light emitted by the light source 2 when the light source 2 is activated so as to allow this light to pass at least partially through the opening 32 of the covering layer 3. , or change color to distinguish itself from the covering layer 3. Thus, when the light source 2 is activated, the light emitted by the light source 2 and impacting the inner face 40 of the photosensitive layer 4 causes the light source 2 to react. photosensitive layer 4, that is to say that this light changes the intrinsic properties of the photosensitive layer 4 so that it becomes at least partially transparent or translucent and allows at least a portion of the light from the source to pass through of light 2 or change of color to distinguish itself from the covering layer 3. In the following description, it will be considered that the photosensitive layer 4 reacts when the light source 2 is active. by becoming at least partially transparent or translucent and allowing at least a portion of the light from the light source 2 to pass through.
    [0011] At least a portion of the light emitted by the light source 2 when it is activated then passes through the photosensitive layer 4 and leaves the outer face 41 thereof, then passes through the opening 32 formed in the covering layer 3 and opens into the interior of the passenger compartment 100. The pictogram defined by the opening 32 then appears illuminated to the occupants of the vehicle. An object of the present invention is to ensure that the ambient light prevailing inside the passenger compartment of the vehicle does not cause the photosensitive layer 4 to react, so that the pictogram defined in the covering layer 3 is not visible to the occupants of the vehicle only when the light source 2 is activated and illuminates the light-sensitive layer 4.
    [0012] Various alternative or cumulative solutions have been provided for this purpose. Thus, a first solution may be to provide that the photosensitive layer 4 reacts only beyond a certain threshold S of illumination, said threshold S being fixed so as to be attained by the light emitted by the source of light 2, but not by the ambient light prevailing inside the cabin. In this way, it is ensured that the photosensitive layer 4 can not react and become at least partially transparent (or change of color if necessary) than when it is illuminated by the light source 2 following an activation of this light. this. In general, that is to say in the case of a closed or undiscovered vehicle driving on a day of average sunlight, the illumination to which a vehicle passenger compartment is subjected does not exceed, on average, a certain value hereinafter referred to as average illumination. According to this first solution, the constituent material of the photosensitive layer 4, here of the paint, will be chosen so that said photosensitive layer 4 reacts only beyond a threshold s of illumination greater than this average value of illumination inside the passenger compartment of the vehicle. Also, for example, it will be possible to choose for the photosensitive layer 4 a material that reacts only beyond a threshold s of illumination greater than the average illumination of a vehicle passenger compartment.
    [0013] Another solution to achieve the aforementioned objective is to provide a filter 5 located on the side of the outer face 41 of the photosensitive layer 4, facing the opening 32 of the covering layer 3, and adapted to block the light to which the photosensitive layer is sensitive and coming from the passenger compartment of the vehicle. Specifically, according to this solution, it is expected that the photosensitive layer reacts to a light located in a given wavelength range X1 - X2. The light source 2 is adapted to emit light located at least in part in said given wavelength range X1 - X2, to which the photosensitive layer 4, whose inner face 40 is impacted by this light, reacts to pass light. an opaque state to at least partially transparent state (or change color if necessary). A filter 5 is then provided located on the side of the outer face 41 of the photosensitive layer 4, that is to say that which is oriented towards the passenger compartment of the vehicle, at the level of the opening 32 of the diaper. 3, and adapted to block at least the light located in the range of wavelength X1 - X2 from the passenger compartment. Thus, the portion of light from the passenger compartment having a wavelength in the range X1-X2 at which the photosensitive layer 4 is sensitive will be blocked by the filter 5 and will not reach said photosensitive layer 4 In the embodiment illustrated in FIG. 3, the stack of layers 8 successively comprises in the S direction of diffusion of the light coming from the light source 2 going from said light source 2 towards the passenger compartment 100, the insert 7, the photosensitive layer 4 attached to the insert 7, a film 10 whose utility will be described later and reported on the photosensitive layer 4, the opaque covering layer 3 reported on the film 10 and comprising the opening 32 forming the pictogram display, and a layer of varnish 5 attached to the covering layer 3 and also filling the cavity 33 defined at the opening 32 by the covering layer 3 and the photosensitive layer 4. This varnish allows advantageously to hide the reliefs present on the visible face of the display device 1 according to the invention by filling the cavity 33 defined by the opening 32 formed in the covering layer 3, thus providing the view of an occupant of the vehicle a smooth and uniform visible surface. The varnish forming this lacquer layer 5 may also be advantageously chosen so as to fulfill the function of the aforementioned filter.
    [0014] A third solution intended to achieve the objective mentioned above, is to provide on the side of the outer face 41 of the photosensitive layer 4, that is to say that which is subjected to ambient light from the passenger compartment 100 the vehicle, opposite the opening 32 of the covering layer 3, a polarizing film 10 for polarizing the light from the cabin 100 so that the polarized light can not react with the photosensitive layer 4. More Specifically, it can be provided that the photosensitive layer 4 reacts only when subjected to light waves located in a given plane P. The light source 2 will be adapted to emit at least light waves located in this plane P given so that the light emitted by the light source 2 is capable of reacting the photosensitive layer 4. The polarizing film 10 will then be chosen to it polarizes the light from the passenger compartment of the vehicle, and passing through the opening 32 of the covering layer 3, so that the light waves passing through said film 10 and impacting the outer face 41 of the photosensitive layer 4 is polarized in a plane P 'different from the plane P. Thus, the light coming from the passenger compartment and passing through the polarizing film 10 before reaching the photosensitive layer 4 can not make it react, because the component waves have been polarized in a plane P 'different from the plane P. The various layers comprising the stack of layers 8 visible in Figure 3 can be reported on each other p for example by gluing or any other suitable method known to those skilled in the art. In the exemplary embodiment described here, the photosensitive layer 4 and the covering layer 3 are produced in the form of paints applied to the insert 7 which provides the structural rigidity of the edge-board portion 110 on which the 1 display according to the invention is arranged. As a variant, it would be possible to dispense with the insert 7 by designing at least one of the covering layer 3 and the photosensitive layer 4 in the form of a structural element made for example of plastic and having a own structural rigidity. In another alternative or cumulative embodiment to the above, the light source 2 is a first light source and the display device 1 25 further comprises a second light source 2 '(shown in broken lines in FIG. 3 ) connected to the control system 9 and adapted to emit light in response to a second control signal following the activation of the first light source 2, the inner face 40 of the photosensitive layer 4 facing the first and at the second light source 2, 2 '. Thus, in this embodiment, it can be provided that the first light source 2 is provided to react the photosensitive layer, causing at least partial transparency thereof or its change of hue, and that the second light source 2 ' is intended to illuminate the inner face 40 of the photosensitive layer so as to enhance the visibility of the pictogram defined by the opening 32 formed in the covering layer for the occupants of the passenger compartment of the vehicle. The second control signal causing the activation of the second light source 2 'can be generated by the control system 9 either automatically, simultaneously with or directly after the generation of the first control signal controlling the activation of the second light source. first light source 2, or following a specific command initiated by an occupant of the passenger compartment of the vehicle.
    [0015] In particular, in the case of the implementation of the display device 1 within a control device 11 of the vehicle hazard warning lights, it is possible, for example, to provide with this embodiment that the first light source 2 is activated in continuous mode 20 by the control system 9 as soon as the dashboard is turned on, in particular when the ignition is switched on (in other words, the vehicle is turned on), this activation provoking the reaction of the vehicle. light-sensitive layer, which can result in a change in the level of transparency or hue thus making the pictogram visible to the occupants of the vehicle, and that the second light source 2 'is activated in flashing mode following a command to activate the warning lights initiated by an occupant of the passenger compartment of the vehicle by the actuation of the control device 11, and thus represent the active state of operation of the hazard warning lights.
