Vehicle lighting device with driver assistance information display
The field of the present invention is that of lighting devices for a motor vehicle, such as a projector equipping the motor vehicle.
Vehicle lighting devices are conventionally used to project on the road ahead of the vehicle a lighting beam that allows the driver of the vehicle to drive safely under night conditions.
These lighting devices are designed to illuminate the road at a prescribed minimum distance for high beam or low beam function. This minimum distance, for example 300 meters for a road function, causes stresses in the light beam, especially in a portion of the beam located between 3 and 15 meters in front of the vehicle.
Indeed, to ensure a minimum illumination required at 300 meters, this illumination is often very important in the portion between 3 and 15 meters. However, it is also regulated since the illumination in this area should not interfere with the driver of the vehicle, in particular by risking reducing the impression of range far away from the beam and / or by dazzling users other as the driver by reflection on the surface of the wet road taken by the vehicle. The illumination in this portion located between 3 and 15 meters in front of the vehicle is thus limited to 12,000 candelas at -4 ° measured along a horizontal axis in a vertical plane.
In the devices of the prior art, it is common to reach this limit value of 12,000 candelas between 3 and 15 meters to succeed in providing the minimum illumination required at 300 meters.
In parallel with this situation, it is increasingly desired to use the vehicle lighting beam to embed information driving assistance.
However, when the portion of the beam located between 3 and 15 meters is at maximum illuminance tolerated, it becomes impossible to embed a positive contrast image. The only available means is then a negative contrast, but it is effective only if the information is delimited by an absence of light in the beam. In such a case, the area where the information is displayed is devoid of light and any element of the road in this area becomes invisible to the driver. If for example a pothole distorts the road and the information covers this pothole, it will be invisible to the driver who can not avoid it.
It is therefore necessary to find another way to make the information visible in the beam while maintaining a level of safety for the driver of the vehicle. The invention solves this technical problem by proposing a lighting device for a motor vehicle which offers sufficient visibility of the road scene and which can display in the beam driving information that the driver can easily detect while driving. not altering his level of security.
The object of the present invention is therefore to design a vehicle lighting device comprising at least one lighting means of a road scene in front of the vehicle arranged to form a first light beam defined by a first illumination, and a device for generating a second light beam defined by a second illumination configured to superpose the second beam on the first light beam, characterized in that a sum of the first illumination and the second illumination is greater than the first illumination and in that the second light beam forms information for driving assistance.
In other words, this means that the second beam has a non-zero illumination and more particularly that the illumination of the driving assistance information is greater than the illumination of the first light beam. The first beam thus forms a luminous background with respect to the information that is projected on at least a part of it. The part of the first light beam on which the information is projected is a limited portion of the first light beam. More precisely, the information is projected at the level of the road scene.
By "driver assistance information" is meant to cover any type of information attracting the attention of the driver. This can for example relate to safety, hazards, including highlighting for example the side of the road taken by the vehicle, or information related to driving, such as speed or direction.
Such a design has many advantages.
Firstly, it makes it possible to display in the light beam information for driving assistance that the driver can detect perfectly, since its contrast with the background makes it visible while keeping enough light to observe the road as a driver. such, and detect its imperfections, in particular.
Secondly, it homogenizes the light beam along the projection axis between a short distance vision and a long distance vision, which gives a visual comfort that has not yet been achieved. Indeed, this homogeneity limits the risk of dazzling that short-range light can generate, especially when driving on a wet road. In addition, the homogeneity of the light beam makes it possible to give a better impression of range of the beam at great distance.
By homogeneity of the beam or uniformity of the beam, it is meant that the illumination of the beam is constant over a given illumination distance projected on the road floor illuminated by the device according to the invention.
According to various features of the invention taken alone or in combination, provision may be made for: the illumination of the first beam in a portion of the road scene between three meters and fifteen meters in front of the vehicle is between 20 lux and 50 lux and in particular will be equal to 30 lux, for this the lighting means can be arranged so that the illumination of the first beam is constant in this portion of the road scene, - the illumination of the second beam in a portion of the road scene between three meters and fifteen meters in front of the vehicle is between 30 lux and 150 lux, - the illumination of the second beam is greater than the illumination of the first beam,
These levels of illumination of the first and second beams distinguish the information projected by the second beam on a background formed by the first beam. a contrast between the first and the second light beam is greater than or equal to zero, it can be between 0 excluded and 5, and more specifically between 2 and 4. These illumination gaps make it possible to improve the readability of the light. projected information on the first beam in positive contrast. the lighting means and the device for generating the second beam are formed by at least one and the same assembly comprising at least one light source emitting a beam of light rays, a scanning system receiving the beam of light rays and the distributing on a surface of a wavelength conversion device; or the same set comprising at least one homogeneous light source and an LCD screen or micromirrors,
By homogeneous light source is meant a surface light source which is distinguished from a pixelated source in that it is not divided into several units of light sources. The LCD screen then comprises a matrix of liquid crystals that can be arranged in front of the homogeneous light source and that modulates the transmission of light from this light source. the lighting means and the device for generating the second beam share at least one light source which generates the first light beam and the second light beam, the light source is pixelated and can be formed by a matrix of individual light sources which extend in the same plane and whose intensity can be controlled individually, - the lighting means comprises at least one optical system whose focal plane coincides with the plane in which the individual light sources extend. The invention also relates to a motor vehicle headlamp comprising a lighting device as previously defined. The invention may also cover a vehicle lighting device comprising at least one lighting means of a road scene in front of the vehicle arranged to form at least a first light beam, characterized in that the illumination of the first beam is constant in a portion of the road scene between 3 meters and 15 meters in front of the vehicle, in particular along an axis of movement of the vehicle.
Thus, the invention makes it possible to ensure a homogeneous luminous background at short distance in front of the vehicle. This homogeneous luminous background at short distance makes it possible, among other things, to give an impression of greater range of the light beam, which makes it possible to bring a better visual comfort to the driver.
In such a case, the illumination of the first beam in the portion of the road scene between 3 meters and 15 meters in front of the vehicle is between 20 lux and 50 lux, and in which the illumination of the first beam in a portion of the road scene located between 200 and 300 meters in front of the vehicle is between 0.5 lux and 2 lux. Other characteristics, details and advantages of the invention will emerge more clearly from a reading of the description given below as an indication in relation to drawings in which: FIG. 1 is a perspective view of a vehicle provided with of a lighting device according to the present invention, - Figure 2 is a schematic view of an embodiment of a light source used by the present invention, - Figure 3 shows the image of the light beam produced by the lighting device according to the present invention projected on a screen located 25 meters in front of the vehicle and perpendicular to the main axis of the beam, - Figure 4 is a side view of a road and a vehicle positioned on this road, equipped with a lighting device according to the present invention, - Figure 5 is a graph showing the illumination of a lighting device according to the prior art r compared to the illumination provided by a lighting device according to the invention, as a function of the distance separating the lighting device according to the invention and the point of impact on the ground on the road.
It should first be noted that the figures disclose the invention in detail to implement the invention, said figures can of course be used to better define the invention where appropriate.
FIG. 1 schematizes a motor vehicle 1 provided with at least one lighting device 2 each comprising at least one lighting means 4 of a road scene 5 situated in front of the vehicle 1. The term "front of the vehicle" is defined The front part of the latter being situated opposite the road scene when the vehicle is moving forward.
The lighting means 4 are arranged to form a first light beam 6. Advantageously, the first beam 6 is regulatory. A beam is considered as regulatory if it meets a national or Community regulation setting a photometric grid to be respected. By way of example for a headlamp, the first light beam can comply with the European regulations ECE R98, ECE RI 12, ECE RI 13 or ECE R123, in their latest amendments which came into force on 9 December 2015 and / or US regulations such as the "Federal Motor Vehicle Safety Standard 108" (FMVSS 108) whose last amendment came into force on December 15, 2015. According to these regulations, the first light beam may include a high beam or a low beam.
Thus, the first light beam 6 has a first illumination corresponding to a luminous intensity of less than 12,000 Candelas (Cd), at an angle β of minus four degrees with respect to a reference line located at the height of the projector. This reference line forms the optical axis of the lighting device 2. The vertical angle β extends in a vertical plane passing through the optical axis. This optical axis intersects, for example, the lighting means 4 of the vehicle 1. According to this vertical angle, a distance D of at least 15 meters in front of the vehicle is illuminated by the first light beam 6, when the lighting means 4 generates a dipped beam.
The lighting device 2 also comprises at least one generation device 7 for a second light beam 10. This generation device 7 for the second beam 10 is configured to superpose the second light beam 10 on the first light beam 6. The second light beam beam 10 has a second illumination and forms a driving aid information 9. Advantageously, the superposition of the light beams 6, 10 is regulatory. The driving assistance information 9 relates, for example, to the speed of the vehicle, signaling information or driver guidance information of the vehicle 1. The driving aid information 9 has a higher illuminance than the vehicle. In other words, the sum of the illuminations of the first beam 6 and the second beam 10 is greater than the illumination of the first beam 10. A contrast between the bottom formed by the first light beam 6 and the information 9 formed by the second light beam 10 is operated by the different illumination values generated between the device 7 for generating the second beam 10 and the lighting means 4.
According to an exemplary embodiment illustrated in FIG. 2, the lighting means and the device for generating the second beam 10 share here a same light source 12 which generates both the first light beam and the second light beam. Figure 2 shows an embodiment of the light source 12 which is in the form of a matrix of pixilated light sources. This matrix comprises a multitude of pixels P located in a plane π which extends here in two directions (y, z). The pixels P are aligned horizontally along the y axis and vertically along the z axis. In this exemplary embodiment, a first pixel group G1 of the matrix is intended to form the first beam 6 and a second pixel group G2 is intended to form the second beam 10. Thus, here the second pixel group G2 is assimilated to the generation device 7. According to this embodiment, each pixel P can be individually controlled, therefore the light intensity and the illumination can be controlled in all or nothing or in a linear manner.
According to an alternative embodiment, the light source 12 may be of the DMD acronym for "Digital Mirror Device" where the rotation modulation of micromirrors makes it possible to obtain a desired light intensity in a given direction.
According to another variant embodiment, the light source 12 may be of LCD type (acronym for "Liquid Crystal Displays") comprising a surface light source in front of which liquid crystals are placed. The movement of the liquid crystals allows or prohibits the passage of light and thus forms a pixelated light source 12.
According to yet another embodiment of the invention, the light source 12 is of the laser type sending a beam of light rays to a scanning system which distributes it on the surface of a wavelength conversion device, such as a plate having a phosphor.
The light source 12 may be associated with an optical system 14 for projecting light onto the road scene. In one embodiment using the matrix of pixels as a light source 12, the optical system 14 has a focal zone coincident with the plane π of the pixel matrix, that is to say, coincides with the light source 12.
When it is possible to control the light intensity of the road scene as permitted by the lighting device 2 according to the invention, it also becomes possible to optimize the homogeneity of the illumination of the first beam 6 and the second beam 10. By homogeneity or uniformity of the beam, it is meant that the illumination of the beam is constant over a given illumination distance measured on the ground.
FIG. 3 represents an example of the image of the first light beam 6 and the second light beam 10 coming from the lighting means 4 projected onto a screen 16 placed perpendicularly to the optical axis 25 meters in front of the vehicle 1. image I of the pixel of the light source has an illumination proportional to the luminance of the pixel, it is the same for the information 9 formed by the second beam 10.
The lighting means is arranged in such a way that the illumination of the first beam 6 and the illumination of the second beam 10 are constant in a portion of the road scene 5 between three meters and fifteen meters in front of the vehicle. The luminous intensity follows the following law in a given direction for each light beam 6, 10:
where E corresponds to the illumination of the beam expressed in Lux, D corresponds to the distance separating the lighting means 4 and the point of ground impact associated with the direction (α, β).
In this way, the light intensity makes it possible to ensure uniform illumination of the ground by the first beam 6. The illumination of the first beam 6 in a portion of the road scene 5 between three and fifteen meters in front of the vehicle 1 is then between 20 lux and 50 lux, which corresponds to a light intensity of between 2000 Cd and 5000 Cd at ten meters. Preferably, reclearance of the first beam 6 is equal to 30 lux. In addition, the illumination of the first beam 6 in a portion of the road scene 5 located 300 meters ahead of the vehicle is between 0.5 lux and 2 lux.
As shown in FIG. 4, the direction (α, β) is defined by the angles α and β. The horizontal angle a corresponds to the angle formed by the beam measured in a horizontal plane with respect to the optical axis of the beam. In other words, the angle a makes it possible to illuminate a more or less wide portion of the road. Preferably, the angle α is between -40 ° and 40 °. The vertical angle β corresponds to the angle formed by the beam relative to the reference line V located at the height of the projector, forming the optical axis of the projector. The angle β illuminates a portion of the road more or less distant from the projector. The angle β can take a value between -10 ° and -4 °.
The control of the luminous intensity of the first light beam 6 and the second light beam 10 can be achieved as a function of the vertical angle β. Indeed, as shown in Figure 4:
where β corresponds to the vertical angle as previously defined, H corresponds to the height of the headlight on the vehicle 1 relative to the ground, and D corresponds to the distance between the point of impact of the first beam 6 or the second beam 10 on the ground for a given vertical angle β.
Thus, between three and fifteen meters in front of the vehicle, the law I (α, β) = E x D2 becomes I (a, β) = E x (H / tan ^)) 2
Under these conditions, the illumination on the ground becomes E = I / D2 and corresponds to a constant for a given intensity and distance. The illumination is homogeneous for each of the beams 6, 10.
In order to comply with the regulatory standards, it is advisable not to exceed a luminous intensity of the first beam 6 with a maximum of 6000 Cd in order to allow the creation of the information for assisting the driving by the second beam 10 in positive contrast with a contrast between 0 and 5, 0 being excluded. The contrast formula of the contours corresponds to:
where LMAX corresponds to the resulting luminance of the sum of the first beam 6 and the second beam 10, and LMIN corresponds to the luminance of the first beam 6. In other words, LMAX corresponds to the luminance of the driving assistance information 9 .
Since the luminance is directly proportional to the luminous intensity, a contrast of one corresponding to a first beam 6 of 6,000 Cd and a second beam of 6,000 Cd is obtained, thus the luminance of the sum of the beams 6 and 10 is equal to 12 000 Cd. A contrast of two corresponds to a first beam 6 of 4000 Cd and a second beam 10 of 8000 Cd, and the luminance of the sum of the beams 6 and 10 is equal to 12 000 Cd. A contrast of three corresponds to a first beam 6 of 3000 Cd and a second beam 10 of 9000 Cd, thus the luminance of the sum of the beams 6 and 10 is equal to 12 000 Cd. A contrast of four corresponds to a first beam 6 of 2400 Cd and a second beam 9600 Cd, and the luminance of the sum of the beams 6 and 10 is equal to 12 000 Cd. A contrast of five corresponds to a first beam 6 of 2000 Cd and a second beam of 10 000 Cd, and the luminance of the sum of beams 6 and 10 is equal to 12 000 Cd.
Thus, the contrast is between 0 excluded and 5, and ideally between 2 and 4 to obtain information 9 having sharp contours with respect to the first beam 6. A contrast between 2 and 4 substantially corresponds to an intensity of the first beam 6 of 4000 Cd with intensity of the second beam 10 between 8000 and 9600 Cd, while respecting the regulatory standards.
These light intensities correspond to an illumination of the second beam 10 in a portion of the road scene 5 between three meters and fifteen meters in front of the vehicle 1 between 30 lux and 150 lux. The illumination of the second beam 10 may be greater than the illumination of the first beam 6 which provides information 9 particularly easy to distinguish while maintaining a beam that illuminates the route taken by the vehicle equipped with the invention. Such a contrast between the bottom formed by the first light beam 6 and the information 9 formed by the second light beam 10 is operated by the difference in illumination generated by the information generating device 7 and by means of lighting 4.
As shown in the graph of FIG. 5, a curve passing through an illumination Emax illustrates the illumination generated by a lighting device of the prior art. This curve is bell-shaped with a maximum illumination substantially at fifteen meters. In contrast, the illumination E0 generated by a lighting device according to the invention is constant up to fifteen meters and then gradually decreases for more distant distances. This makes it possible to provide firstly a controlled and homogeneous illumination in close light, and secondly a reduced level of ground light, which limits the effects of dazzling for users in case of wet road. An electrical consumption of the lighting device is also optimized in the sense that there is no excess light in areas of the road scene that does not require strong lighting.
