Definitions
- the invention relates to a glazing, in particular a windshield, allowing the capture of image data in a motor vehicle in association with a camera system including the ADAS type (Advanced Driver Assistance Systems).
- the invention also describes a device combining said glazing (said windshield) and said camera for such an information display.
- ADAS Advanced Driver Assistance Systems
- cameras placed behind the windshield allow these ADAS to assist the driver while driving.
- Such an ADAS device can notably have the following functions, without the following list being exhaustive:
- the device comprises at least one camera disposed behind the windshield of the vehicle.
- a congestion problem arises. Indeed, the space available on the front glazing of a vehicle for such devices is very limited because they must not interfere with the driver's vision, for obvious safety reasons.
- Such an area 100 sometimes referred to as Y0 in the field, is usually located in the central and upper part of the windshield as shown in Figure 1 attached.
- the camera or cameras are oriented with a certain angle vis-à-vis the surface of the windshield,
- the lens and the image sensor (CCD or CMOS) which coupled to it are oriented directly to the image capture zone, in a direction close to the parallel to the ground, that is to say only slightly inclined towards the road, as illustrated by the attached figures.
- the camera is oriented towards the road at a low angle and adapted to perform the above functions.
- a correct field of view accessible to each camera therefore requires that the external beam collected (or rather the set of beams collected at a predefined solid angle) passes through each of said cameras a specific window 101 of trapezoidal shape on the windshield, as shown in Figure 1 attached.
- Such a configuration further implies the use of a black coating 102, such as a layer of enamel or black lacquer, on the entire surface of the glazing arranged facing the device incorporating the ADAS camera, including its housing, in order to hide this one.
- a black coating 102 such as a layer of enamel or black lacquer
- the black printed surface 102 on the glazing can take very large dimensions, in proportions likely to significantly reduce the overall field of view of the driver through the windshield.
- it is almost substantially the entire surface of the windshield in its upper central portion which must be covered with a black printing layer, as illustrated in Figure 1 attached. .
- the aim of the present invention is to propose a solution that makes it possible to solve the problems described above and, in particular, bypassing the space problems described above, in particular by reducing the black surface on the windshield to isolate or mask the ADAS cameras present at the back of the glazing.
- the above problem could be solved by changing the orientation of the optics of the camera so as to switch it from an angle ⁇ to the vertical.
- the present invention relates to a laminated windshield for a motor vehicle, comprising two sheets of glass bonded together by a spacer made of a refractive index thermoplastic material ni, in which:
- thermoplastic interlayer has a cut-out portion in the upper part of the windshield
- said cut-off portion is filled by a multilayer film forming a waveguide from a low point of entry of the light radiation onto the face of the windshield exposed to the outside of the vehicle towards a high point of exit of said radiation on the face of the windshield disposed towards the passenger compartment of the vehicle,
- said multilayer film comprises layers of a first refractive index material n 2 such that ni> n 2 and a second material reflecting at least a portion, and preferably substantially all, of the light radiation, said second material being disposed on either side of the layer of first material for confining therein said light radiation.
- the refractive index refractive index n 2 is less than the refractive index
- the refraction refractive index n 2 is less than the refractive index and at least 0.05 and preferably at least 0.1.
- the interlayer is a PVB.
- the first material is chosen from aliphatic urethane acrylate polymers, optionally fluorinated.
- the first material is chosen from aliphatic urethane acrylate polymers, optionally fluorinated.
- the second light reflecting material is a material consisting of a thermoplastic material of refractive index n 3 , chosen such that n 2 > n 3 .
- the refractive index n 3 is smaller than the refractive index n 2 of less than 0.05.
- the interlayer is PVB
- the first material has a refractive index n 2 between 1.32 and 1.43
- the second material has a refractive index n 3 between 1.31 and 1.42.
- the first material has a refractive index n 2 of between 1.32 and 1.43 and the refractive index n 3 is between 1.3 and 1.4.
- the second material is chosen from aliphatic urethane acrylate polymers, optionally fluorinated.
- the second light reflecting material may be a stack consisting of at least one thin layer of a metal and / or inorganic materials, especially chosen from oxides or nitrides.
- the second light-reflecting material consists of a silver layer or a stack of thin layers comprising at least one layer of silver. Said cutting portion is normally disposed in a central upper zone of the glazing, preferably swept by the windscreen wipers.
- said cutting portion is of rectangular shape.
- the invention also relates to a device for capturing images, through a windshield, coming from a zone for capturing a light radiation from a low point of entry of the light radiation onto the face of a light. windscreen exposed to the outside of the vehicle towards a high point of exit of said radiation on the face of the windscreen disposed towards the passenger compartment of the vehicle, said device being characterized in that it comprises:
- a camera in particular an ADAS camera, comprising a lens and an image sensor,
- said camera is disposed in the passenger compartment behind said windshield at said high point of output of said radiation, so as to receive the light radiation from said capture area, after passing through said windshield.
- FIG. 1 illustrates a perspective view of an image capture device currently marketed, as previously described.
- FIG. 2 schematizes a windshield according to the invention, in sagittal section, as well as the path of a light radiation from the outside of the vehicle to the objective of a camera for example ADAS placed behind the screen. broken.
- FIG. 2 illustrates an embodiment of the present invention, in more detail but without limitation.
- FIG. 1 there is shown a laminated glazing along a sagittal sectional plane.
- the arrows 3i to 3s illustrate the path in the windshield of an initial light radiation 3 arriving from the outside environment of the vehicle from a lower part of the windshield and in particular from the road zone. that one seeks to observe by an ADAS camera 2 arranged in a higher part of the windshield 1.
- the terms "lower part” and “upper part” used in the present invention are relative and simply indicate that the point of entry of the light radiation is in a region of the windshield substantially lower than its exit point. in the direction of verticality, as shown in Figure 2.
- the term "light radiation” means all the light rays arriving at a certain solid angle and which are sought to be captured via the camera 2. In FIG. 2, it has been shown, for the sake of clarity, this radiation by a single beam 3.
- the light beam 3 outside the vehicle normally picked up by the camera 2 arrives with an angle of incidence on the windshield that is very flat with respect to the horizontal, so that the installation of the camera 2 directly on the rear of the windshield 1 conventionally imposes, for the capture of said beam, that it is also positioned in such a direction, that is to say that its lens itself has a very sharp angle flat to the road and to the inner surface of the windshield, as shown in dashed lines in Figure 2.
- the black lacquered or enamelled surface 102 drawn on the glazing to conceal the installation may take on very large dimensions, possibly to a considerable extent reducing the overall field of view of the device. driver through the windshield itself.
- the glazing 1 shown in FIG. 2 is a conventional laminated windshield comprising a first glass sheet 4 and a second glass sheet 5, the two glass sheets being bonded to each other by an interlayer 6 made of glass thermoplastic, usually polyvinyl butyral (PVB).
- the windshield is obtained by hot lamination of the elements 4, 5 and 6.
- the interlayer may of course comprise several sheets of thermoplastic material of different natures, for example different hardnesses to ensure an acoustic function, as for example described in the publication US 6,132,882, in particular a set of PVB sheets of different hardnesses.
- one of the glass sheets can be thinned compared to the thicknesses conventionally used.
- the interlayer may also according to the invention have a wedge shape, especially for a HUD application (Head Up Display for head-up display). Also one of the sheets of the interlayer can be tinted in the mass.
- Zone 7 has very small dimensions, related to the dimensions of the windshield.
- the portion 1 1 corresponds to the hatched area in FIG. 2.
- the inserted multilayer film 8 comprises several successive layers, of which a first material in the form of a plastic layer 9 positioned at the center of the film and having a refractive index n 2 below or equal to, preferably less than, the index of refraction and the material constituting the interlayer 6.
- This first material layer 9 of index n 2 may be in particular another plastic material (a polymer), in particular a plastic having adhesion properties to the surface of glass or other plastics.
- the material 9 is advantageously chosen and preferably so that its refractive index n 2 is significantly lower than that of the material constituting the intermediate sheet 6.
- significantly lower is meant a difference in index of from minus 0.05 and preferably at least 0.1.
- the material chosen to constitute the material 9 may advantageously be chosen from acrylate polymers, in particular the optionally fluorinated aliphatic urethane acrylate polymers, whose refractive index can vary between 1, 31 and 1, 42 according to the formulation.
- acrylate polymers in particular the optionally fluorinated aliphatic urethane acrylate polymers, whose refractive index can vary between 1, 31 and 1, 42 according to the formulation.
- Such adhesive polymers are for example sold by Nordland under the references NOA 1315, NOA 132, NOA 1327, NOA 1328, NOA 133, NOA 13685, NOA 1375, NOA 138, NOA 142.
- this first material of refractive index n 2 there are two layers 10 of a second material for confining the radiation entering the portion 1 1 by multiple internal reflections at the interface between the first and second materials.
- the second material constituting the layers 10 is of organic nature, in particular is a plastic polymer and preferably is a thermoplastic.
- the material 10 has a lower refractive index n 3 , preferably slightly smaller than that (n 2 ) of the layer of material 9.
- slightly weaker is meant a difference in index between the indices n 2 and n 3 of less than 0.05 and preferably less than 0.04, more preferably less than 0.03 or even less than less than 0.02, or even less than 0.01.
- the second material may be inorganic material.
- it may be an inorganic layer, in particular or a stack of thin layers for reflecting the light beam arriving at its surface.
- the second light reflecting material is a stack consisting of at least one thin layer of a metal and / or inorganic materials, especially chosen from oxides or nitrides.
- the second light-reflecting material consists of a layer of a metal or a stack of thin layers comprising at least one layer of metal.
- This metal is preferably silver.
- the thickness of the silver layer is for example between 10 nm and 50 nm.
- the multilayer film 8 is thus configured according to conventional optical techniques so that the initial light beam 3 enters at one end. lower portion 1 1 (low entry point of the light) with a suitable angle a, then undergo multiple internal reflections, substantially total at the interface between the materials 9 and 10 as indicated by the arrows 3 2 at 3 3 .
- the initial ray propagates up to the other end of the multilayer film 8 (high point of light exit) without loss of information, by multiple reflections in the material 9 framed by the layers or strips of the material 10, along the cut portion 1 1.
- the multilayer film 8 thus acts as a waveguide, exploiting the refractive properties of light at the interface between two materials of different indices, according to the principles already well known in particular in the field of optical fibers.
- the metal layers surrounding the material 9 play a role of mirror and allow in the same way as previously the light reflection and its confinement along the portion 1 1 to an exit point disposed in an upper part of the glazing.
- the difference in index between the thermoplastic material (or materials) constituting interlayer 6 (of index n i) and the first material of index n 2 is adapted, that is to say sufficiently high in the sense previously described, for the radiation to provide a sufficiently low angle of entry of light in the space formed between the materials 9 and 10, that is to say -desidable to allow substantially lossless light guidance along the thus-generated light cavity in the spacing between the materials 9 and 10 by internal and multiple reflection at the interface between these two materials, as illustrated by the 3 2 a third arrows in Figure 2.
- the light radiation 3 7 is refracted by the surfaces 5 of the glazing glass sheet and recovered at the outlet of portion 1 1 the camera lens 2 according to a final direction of the radius schematically by the arrow 3s, as shown in Figure 2.
- a final direction of the radius schematically by the arrow 3s as shown in Figure 2.
- such a configuration allows the camera 2 to tilt by an angle ⁇ towards the vertical with respect to its theoretical positioning behind the windshield, that is to say in the absence of the multilayer film 8 positioned in the arrival portion 1 1 of the beam to be collected.
- FIG. 1 shows in solid lines the trapezoidal zone according to the present configuration and in dotted lines the trapezoidal zone in a configuration according to the present invention.
- the invention it therefore becomes possible to strongly limit the surface of the black printed area on the windshield or alternatively to place a greater number of cameras in the accessible area of the windshield, especially for stereoscopic vision. or to increase the control points on the road and / or the number of functions as described above.
- the choice of the materials constituting the layers 9 and 10 and their thicknesses is carried out according to the techniques of the art, depending in particular on the initial angle of incidence of the beam 3, that is to say of the zone on the road, in front (or behind) of the vehicle that is to be viewed, and in relation to the desired positioning of the camera 2 behind the windshield, in particular the angle ⁇ sought, as it has previously described.
- interlayer 6 "classical" PVB with a refractive index of about 1.48,
- refractive index material n 2 between 1.32 and 1.43.
- a material may be chosen from optionally fluorinated aliphatic urethane acrylate polymers such as those described above,
- such a material may be chosen from optionally fluorinated aliphatic urethane acrylate polymers such as those described above.
- the cutting portion 1 1 normally has small dimensions, relative to the surface of the windshield or glazing and is disposed on the glazing substantially facing the ADAS or cameras located at the rear of the glazing, in the passenger compartment.
- the cutting portion January 1 is as limited as possible in its dimensions and may have any form useful for the proper implementation of the present invention, in particular the routing of light rays to the (or cameras.
- said cutout has a rectangular shape, with dimensions of the order of 5 to 20 cm for the largest length and 4 to 15 cm for the smallest length.
- the shape and dimensions of the cutting portion are also configured according to the techniques of the art so as to effectively and selectively collect all the incident light radiation passing through the windshield at the low point of the cutting portion, and from a solid angle range outside the vehicle and from the area in front of the vehicle that is sought to capture via the lens 2 of the camera.
