    [0001] The invention relates to the field of lighting and / or signaling, in particular for motor vehicles. BACKGROUND OF THE INVENTION More particularly, the invention relates to a method for controlling a global light beam emitted by a motor vehicle headlamp and obtained by the addition of intermediate beams produced by at least two lighting means, as well as to the modules which can allow the implementation of such control methods.
    [0002] A motor vehicle is equipped with headlamps, or headlights, intended to illuminate the road in front of the vehicle, at night or in the case of reduced luminosity. These projectors can generally be used in two lighting modes: a first mode "high beam" and a second mode "low beam". The "high beam" mode provides strong illumination of the road far ahead of the vehicle. The "low beam" mode provides more limited illumination of the road, but still offers good visibility without dazzling other road users. These two lighting modes are complementary. The driver of the vehicle must manually change the mode according to the circumstances, at the risk of dazzle inadvertently another user of the road. In practice, changing the lighting mode manually can be unreliable and sometimes dangerous. In addition, the dipped beam mode provides visibility sometimes unsatisfactory for the driver of the vehicle. To improve the situation, projectors with an adaptive lighting function (known in particular under the acronym AFS for "Adaptive Frontlighting System") have been proposed. Such an adaptive lighting function is intended to detect automatically, for example by the image processing acquired by an on-board camera, a user of the road likely to be dazzled by a lighting beam emitted in fire mode. by a projector, and to modify the outline of this light beam so as to create a shadow zone at the location where the detected user is located. The advantages of such a function of adaptive lighting are multiple: comfort of use, better visibility by 3025151 2 compared to a lighting in dipped beam mode, better reliability for the change of mode, risk of dazzling greatly reduced, driving more sure. Document EP2280215 describes an example of a lighting system for a motor vehicle headlamp, with an adaptive lighting function. The system comprises four primary optical elements, in each of which three light sources are associated with three respective light guides, as well as four secondary optical projection elements, in this case lenses, respectively associated with the four primary optical elements. The light emitted by each light source enters the associated light guide and exits through an outlet end of the rectangular shaped guide. The arrangement of the primary optical elements and their associated secondary optical element causes the light emitted by each optical guide output end to be projected by the secondary optical element so as to form a vertical light segment at the front of the vehicle. The light segments produced overlap partially in the horizontal direction. The lighting sources that can be ignited independently of each other are then played selectively to obtain the desired lighting and to make a non-glare beam for other road users. The beam is thus divided into a plurality of light segments that can be turned on or off. The adaptive lighting beam 20 which can thus be achieved solely by electronic ignition control of the light sources, and without mechanical movement of an additional cache piece, is known in particular as a matrix beam. It is understood that such a lighting and / or signaling method and the light modules used or studied until now for this purpose are particularly advantageous for the driver who has a road scene in front of him which is better illuminated than with a beam of low beam type, and for other road users who do not risk glare. However, it can be seen that turning off the pixels corresponding to one or another light segment contributes to a reduction in the intensity of the overall luminous flux that can be obtained with high beam operation.
    [0003] The aim of the invention is to propose an alternative to the light beam control methods as described above, which makes it possible to achieve the non-glare beam function, without this decrease in intensity of the overall luminous flux.
    [0004] For this purpose, the subject of the invention is a method for controlling a global light beam emitted by a motor vehicle headlamp and formed of selectively activatable beam portions, in which detection is carried out on a road stage at the vicinity of the vehicle, a third vehicle likely to be dazzled by said overall light beam, and a target zone in said overall beam including said third vehicle, in which then is identified lighting means carried by said projector which perform the portions of beams providing illumination of said target zone, and in which a movement of said lighting means identified in the previous step is piloted, so as to create a zone of less illumination corresponding to said target zone, while Now illuminated said lighting means. According to other features, said lighting means comprise light sources and optical electromechanical microsystems respectively associated with one of the light sources, each light source being controlled individually in ignition while the electromechanical microsystems 20 are controlled individually moving. Thus, as has been previously stated, it is possible to improve the otherwise known solutions by keeping intact the light intensity of the overall beam, since none of the light sources of the light module (s) are extinguished and the light the pixels corresponding to the dark area are moved laterally rather than extinguished. In an advantageous embodiment, said electromechanical microsystems are controlled individually in rotation. And it is expected that said electromechanical microsystems are rotated over a narrow angular range between a standard position and an offset position, while the associated light sources are kept lit, so that the beam 3025151 4 emitted by the sources of light and reflected by said electromechanical microsystems identified offset position illuminates the vicinity of the target area. This increases the light intensity in the immediate vicinity of this target zone, in an area where the visibility is poor because of the lighting of the headlights of the cruising vehicle. This allows, for example, to better see a vehicle driver coming out of his stopped vehicle in case of failure. Thus, more intense illumination of the edges of the target area, with light sources that retain the same light intensity.
    [0005] The overall light beam may consist of a beam of non-glare road lights of the matrix type: the overall light beam may be obtained by a set of lighting means, each of said lighting means being dedicated to the respective lighting a portion of the overall light beam, and moving only one of the lighting means to move to form said area of least light corresponding to said target area; the overall light beam can also be obtained by the addition of intermediate beams made respectively by separate sets of lighting means, and moving one of the lighting means of each set to move to create the zone of lesser illumination corresponding to said target area. By addition of intermediate beams, it is understood that the corresponding intermediate beams overlap each other. In this case, it is possible to move a lighting means of a first set in a first direction and a lighting means of the second set in an opposite direction. According to one characteristic of the invention, the beam portions consist of vertical segments juxtaposed with each other, the displacement of the lighting means generating the displacement of at least one of said segments and its superposition on other segments of the beam overall bright.
    [0006] The invention also relates to a light module for implementing the control method as described. The module comprises a light source and optical deflection means, and it is characteristic of the invention that said optical deflection means are movably mounted. The light source is permanently immovably mounted in the module. An optical system may be provided for emitting a light beam, the optical deflection means then being interposed between the optical system and the light source. According to various features of the method of the invention, taken alone or in combination: the optical system consists of a reflector and a projection lens; the light source comprises a plurality of semiconductor sources; these semiconductor sources may in particular be light-emitting diodes, or laser diodes, associated with phosphor parts; in the latter case, the laser diodes are arranged upstream of the optical deflection means while the phosphor parts are arranged between the optical deflection means and the optical system. It will be understood that other arrangements could be provided without departing from the context of the invention: for example, it could be possible to have a laser diode, or a blue or ultraviolet light emitting diode, which is upstream of the electromechanical microsystem while a phosphorus is deported, and one could also have a white source (formed by a blue light-emitting diode and phosphor, or by at least one laser diode and phosphorus) which is entirely upstream of the optical deflection means. The optical deflection means may advantageously consist of optical electromechanical microsystems, mounted for rotation between a standard position in which said systems are capable of deflecting the light rays towards a first zone of the optical system and an offset position in which said systems are able to deflect the light rays to a second zone of the optical system. And the optical electromechanical microsystems can then be rotatably mounted to move from said standard position to said offset position, with a rotation angle of between 2 ° and 7 °, the optical electromechanical microsystems used herein having a deflection angle. about +/- 7 °. According to one characteristic of the invention, each optical electromechanical microsystem consists of a mirror capable of deflecting the light rays emitted by the light source and mounted on an electromechanical microsystem provided with an axis of rotation and carried by the module. The electromechanical microsystems can be arranged in a linear matrix.
    [0007] It can be provided that a primary optical device, in particular a collimating lens, is disposed between the light sources and the optical deflection means. The invention also relates to an automotive lighting system comprising at least one light module, and advantageously, it can be provided to have at least one light module in a left headlight of the motor vehicle and at least one light module in a headlamp right of the vehicle, said modules being arranged so that the intermediate light beams they generate add up to generate a global light beam. The system may further comprise means for detecting the third vehicle on a road scene, means for analyzing the received detection information and calculation means for giving a command to move the optical deflection means. Other features and advantages of the present invention will become more apparent from the description and the drawings, of which: FIG. 1 is a schematic side view of a light module according to a first embodiment; in which a light source, a collimating lens, optical deflection means, a reflector and a projection lens are made visible; FIG. 2 is a schematic representation of the module of FIG. 1, seen from above, in which the reflector is made transparent to facilitate the visibility of the optical deflection means, and the axes of rotation of the electromechanical microsystems that compose them; FIG. 3 is a schematic representation similar to that of FIG. 1, of a light module according to a second embodiment in which a light-emitting laser diode specific to this embodiment, a lens, is made visible here; collimator, optical deflection means, a phosphor pellet associated with the laser diode, a reflector and a projection lens; and FIGS. 4 and 5 are diagrams illustrating the operation of the invention in which intermediate beams are rotated to modify the overall light beam emitted by a motor vehicle headlamp.
    [0008] We will first describe a light module for lighting and / or signaling of a motor vehicle according to a first embodiment illustrated in Figures 1 and 2. The light module 2 comprises at least one light source 4 capable of emitting light rays in the direction of first optical deflection means 6, and an optical system 8. At the output of the module, an intermediate beam is thus produced, which can be completed by the addition of other intermediate beams obtained by d other light modules arranged nearby in the same projector of the motor vehicle or in another projector. The various components of the modules are arranged in such a way that the optical axis of the module corresponding to the axis of emission of the light rays at the output of the module is substantially parallel to the main axis of emission of the rays at the output of the module. the source of light. Here, the optical axis of the module is longitudinal. In the following description, the term optical plane will be used to define the vertical plane comprising the optical axis, being observed that the optical plane corresponds to the plane of the sheet in the illustration of FIG.
    [0009] Each light source here consists of a semiconductor source, and for example a light-emitting diode, which may be associated with a printed circuit board and a radiator for cooling the electronic components carried by said card.
    [0010] As can be seen in FIG. 2, the module comprises three separate light-emitting diodes 10 reported on a common board 12 of printed circuits. It will be understood that other configurations, in number, in geometric arrangement, can be chosen without departing from the context of the invention.
    [0011] The first optical deflection means 6 consist of a plurality of electromechanical microsystems (known by the acronym MEMS for the English translation "MicroElectroMechanical Systems"), arranged in a line array so that each of these electromechanical microsystems is arranged opposite a light-emitting diode (or a "light chip" of the diode). The electromechanical microsystems extend longitudinally forward of the light sources, and they consist of movable mirrors 14 able to reflect part of the light rays emitted by the light source. In an alternative embodiment, each mirror is rotatably mounted about an axis 16 carried by the module, so as to pivot between two extreme positions, namely a first standard position and a second optical offset position. For a diode centered on the optical axis and the associated electromechanical microsystem also centered on the optical axis, there are two extreme positions, obtained by mechanical stop of the rotation of the axis, in that the first standard position is calibrated so that the rays reflected by the mirror thus oriented impact the optical system disposed downstream substantially in the optical plane, while the second optical shift position is calibrated so that the rays reflected by the mirror thus oriented impact the optical system to a distance from the optical plane corresponding to the desired width of the light segments composing the intermediate light beam.
    [0012] In the first standard position, the mirror extends in a plane perpendicular to the optical plane and having the transverse axis, while in the second offset position, the mirror is inclined relative to this transverse axis. For this purpose, to move from one to the other extreme positions, the axis 5 of rotation of the mirrors is in the optical plane and forms with the optical axis substantially an angle of 45 °. It will be understood that when all the mirrors are in the same position, whether in the standard position or in the offset position, regular complementary beams are obtained, with the component segments arranged at regular intervals, a transverse beam shift. intermediate being formed between a first arrangement of the optical deflection means in which all the mirrors are in the standard position and a second arrangement of the optical deflection means in which all the mirrors are in the offset position. On the other hand, if only one of the mirrors of the optical deflection means is rotated in the offset position, the complementary beam is no longer regular, and one segment of the matrix beam overlaps with another. It is observed that the matrix of electromechanical microsystems according to the invention has a different operation from that of other matrices known elsewhere, as in a DLP® system for example. While in such systems, the light reflected by the mirrors is either directed to the projection optics when the mirrors are in the standard position, or directed to a non-reflective surface when the mirrors are in the offset position, In order to form an on / off system in which certain parts of the image are darkened, the matrix according to the invention does not generate extinction of part of the beam, but only a displacement of this or that part. This is particularly due to the advantageously narrow angular range of rotation chosen, of the order of 2 ° to 7 °, which allows that in one or other of the extreme positions, the light reflected by the mirrors is directed integrally to the projection device disposed downstream in the path of the light rays.
    [0013] In their standard position, the optical deflection means are able to deflect the light rays towards a first zone of the optical system and in their offset position, the same deflection means are able to deflect the light rays towards a second zone. of the optical system. It is also particularly interesting to note that the microsystems used in the invention are not binary. By this is meant that the angle of rotation can be chosen indifferently in the angular range of + 1-7 °, without being limited to one or the other of the extreme positions, by voltage control or control commands. current according to the type of selected microsystems, electrostatically controlled, piezoelectric or magnetic for example. Optionally, a primary optic is disposed between the first optical deflection means and the light source, in addition to the optical system disposed at the output of the module, to improve the efficiency and to avoid beam overlaps. This primary optic may be a collimating lens 18. The optical system 8 is disposed at the output of the module in the path of the light rays emitted by the light-emitting diode 10 and deflected by the electromechanical microsystems 14. As illustrated, the optical system comprises a reflector 20 and a projection lens 22. It will be understood that other arrangements of optical system can be implemented without departing from the context of the invention.
    [0014] The module further comprises detection means on the illuminated road scene of a vehicle not to be dazzled, means for analyzing any information transmitted by these detection means, as well as control means for the light sources and electromechanical microsystems. These control means can make it possible to turn on, turn off or modify the luminous intensity emitted by each light source of each module, while the detection means can consist, for example, of a camera facing the road scene extending in front of the vehicle, and associated image processing means, which allow the development of a detection information that the detection module is able to send to the control means for ignition, the microsystems rotation 3025151 11 electromechanical being generated by the control means based on this detection information. A light module 2 as just described makes it possible to implement the method of controlling a global light beam emitted by a motor vehicle headlamp and obtained by the addition of intermediate beams produced by at least two lighting means according to the invention. At first, light rays are emitted by the diodes 10 of the module 2 when the control module receives information relating to the automatic detection of driving conditions in traffic lights or information relating to a control of the driver. The spokes are directed substantially parallel to the optical axis towards the electromechanical microsystems formed of moving mirrors 14 which are in the first standard position, and the result is an intermediate beam of the "high beam" type, divided into a number of segments. equal to the number of diodes and 15 mirrors. When the detection means send information to the control module relating to the presence of a vehicle on the road scene illuminated by the beam previously produced, the control module identifies which is the target zone, that is to say the area in which said detected vehicle is present, and it determines which diodes and the associated electromechanical microsystem provide lighting in that area. Instead of switching off the corresponding diodes, or rotating the electromechanical microsystems by an angle such that the deviated rays no longer meet the projection device, the continuity of the ignition of the diode is promoted here. a rotation of only a few degrees of the mirror. The light rays deviated by a mirror represent a light segment, here vertical, of the intermediate beam and the rotation of a few degrees of a mirror generates a transverse displacement of the corresponding light segment.
    [0015] A use of this control method can be provided with a segmented overall beam obtained directly from a light module, without the addition of segmented intermediate beams, and it is then understood that the transversal displacement of a light segment of the beam allows the creating a target area 5 allowing the non-glare of a detected vehicle, with greater illumination on one side of the target area, in the direction in which the light segment was moved. And it is understood that it is necessary to control the rotation of the movable mirrors of the light module by a distance sufficient for the light segment to move transversely of the length equal to that of the target area.
    [0016] FIGS. 4 and 5 illustrate an advantageous embodiment in which the overall light beam obtained by the addition of two complementary intermediate light beams, in the case of a motor vehicle lighting assembly in which two modules The luminaires as described above are housed in series in a projector whose overall light beam is shown to the right of the figures, resulting from the addition of the intermediate beams of the two modules shown on the left of the figures. Figure 4 illustrates a light beam projected on a vertical wall and corresponding to a standard state in which no vehicle is detected. A first module comprises three diodes, and when they are lit, it is formed, by reflection of the light emitted on the optical deflection means in particular, a first intermediate beam 24 composed of three segments spaced one of the other, in the transverse direction, of a first determined interval dl. A second module comprises four diodes, and when they are lit, a second intermediate beam 26 is formed composed of four segments spaced from each other, in the transverse direction, a second determined interval d2 . The modules are oriented with respect to the optical axis of the vehicle, so that, by addition of the two intermediate beams, an overall beam 28 is formed composed of a succession of segments, it being understood that the segments of the first beam intermediate have a width equal to the second interval d2 to be housed between the segments of the second intermediate beam and conversely the segments of the second intermediate beam 30 have a width equal to the first interval dl to be housed between the segments of the first intermediate beam. As illustrated, one can predict that the segments all have the same dimension and that the intervals between the segments are the same from one intermediate beam to another.
    [0017] It should be noted that according to the invention, the width of the segments may vary from one segment to another depending on whether they are positioned at the center of the beam or at the edges. The central segments are thus provided narrower than the lateral segments. In the same vein of a nonhomogeneous arrangement according to the position of the segments, the intervals between the segments of a sub-beam may vary, and the rotation angles of the segments may differ from one segment to the other. other. Also, it can be provided that the segments of the edge are fixed and they are controlled simply in extinction or ignition. This avoids having to manage a high value rotation angle for their displacement, complicated to implement, while this displacement may not be justified given the position of the segment on the road. The system can therefore combine moving segments and fixed segments. FIG. 5 illustrates a state in which a vehicle has been detected and in which it is sought to create in the overall light beam 28 a target area 30 in which no potentially dazzling light beam is formed. For this purpose, the first intermediate beam 24 is modified by transverse shift of a light segment in a first transverse direction, while the second intermediate beam 26 is modified by transverse shift of a light segment in the opposite transverse direction. This allows, as can be seen in the figure, to provide a displacement of the segments only half of the expected interval between the segments of each intermediate beam. And this also allows lighting on either side of the target area. When the intermediate beams are added, one half of the segment displaced in an intermediate beam is superimposed on one half of a segment which remains fixed in the other intermediate bundle. It can thus be observed in FIG. 5, two darker zones 32 and 34 disposed on either side of the target zone 30, the zone 32 being here obtained by the superimposition of the segment 38 and a segment that has remained fixed beam 24 while the zone 34 is obtained by superposition of the segment 36 and a fixed segment of the beam 26. A second embodiment of the invention is illustrated in Figure 3. The module differs from what has been described in the second embodiment in that the light sources are formed by a series of laser sources 40, which are associated with phosphorus pellets 42, for the formation of a white light regulation. The optical deflection means remain unchanged and the light rays which they deviate, whether in their standard position or their offset position, are directed towards the phosphor pellets disposed between the optical deflection means and the reflector of the system. optical. It is understood that the method is the same in the case of this second embodiment. As a variant of each of the two embodiments described above, and more generally in an advantageous variant of the invention, it can be provided that each electromechanical microsystem has two positions offset on either side of the standard position, so that the electromechanical microsystem can be rotated in one direction or the other from the standard position. The control module determines according to the driving conditions (driving left or right, vehicle not to dazzle followed or crossed, ...) 20 in which direction the mirror is rotated. It can thus be said that electromechanical microsystems are mobile between three positions and no longer between two positions. In this case, the microsystems have a central standard position and two extreme positions obtained by a positive or negative shift on either side of this standard position. In this case, the two extreme positions 25 provided on either side of the standard position are calibrated so that the rays reflected by the mirror thus oriented impact the optical system at a distance from the optical plane corresponding to half the desired width. light segments composing the intermediate light beam. It is observed that in this case, to be able to move the segment by only half of its width, it must have a width twice that of the area where it is desired to create a shadow. This may lead to having to create a shadow twice as wide, in the case of a vehicle centered on two segments. It is then possible to keep the displacement of a half-segment by providing to rotate the module globally to center the shadow on the vehicle. Note that in the case of the presence of several vehicles on the road scene, it will be interesting to give priority to the most central vehicle in the beam to drive this global pivoting. According to another variant of the invention, it can be provided, particularly in the case of a "pixel lighting", that the displacement can be horizontal or vertical. As previously described, the horizontal displacement of a beam portion is made on each segment individually, and it is interesting to note that the vertical displacement is performed on the module as a whole. It can be used for this electromechanical microsystems controllable on two perpendicular axes. With such devices, the light of the zone to be extinguished can be "ejected" as well laterally, which is preferable for the zones 15 in the vicinity of the horizon, than vertically, upwards or downwards, which can be more interesting for high areas. The foregoing description clearly explains how the invention makes it possible to achieve the objectives it has set itself, and in particular to propose an intermediate light beam control method which allows the realization of a non-glare beam of light, without overall loss of light intensity, and advantageously more intense lighting of the immediate edges of the area made dark to avoid dazzle the oncoming vehicle or rolling in front. 25
