LIGHTING DEVICE FOR A MOTOR VEHICLE HEADLIGHT

Description

[0001] The invention relates to a lighting device for a motor vehicle headlight for detecting and selectively masking out a light-emitting object present in front of the lighting device in a segmented light distribution, which lighting device comprises the following: a light generation unit comprising a plurality of luminous pixels arranged in rows and columns in a luminous pixel array, wherein the light generation unit is configured to emit a segmented light distribution in a main emission direction in front of the illumination device, a light sensor device for detecting light from a light-emitting object having a first light sensor, which first light sensor has a plurality of first sensor pixels arranged in a row, wherein the first sensor pixels are configured to detect luminous flux of light incident on the first light sensor in a wavelength range from 380 nm to 780 nm, a control unit which is connected to the light generation unit and the light sensor device and is configured to control the light generation unit to generate the segmented light distribution.

[0002] Furthermore, the invention relates to a motor vehicle headlight with at least one lighting device according to the invention.

[0003] ADB systems, or ADB vehicle headlights, typically comprise an ambient recording device, such as a camera or camera system, and a vehicle headlight system. The well-known functionality of an ADB system is that the vehicle headlight system controls the vehicle headlights based on information provided by the ambient recording device to the vehicle headlight system, for example, masking out or dimming corresponding areas of the light distribution generated by the vehicle headlights.

[0004] In matrix-type ADB systems, a blanking area is usually created by switching off / dimming the corresponding light source. The aforementioned lighting device for a motor vehicle headlight is preferably a matrix-type device.

[0005] Particularly from the perspective of motor vehicle headlight manufacturers, it is disadvantageous with ADB systems that the ambient recording device is structurally separate from the motor vehicle headlight system. Typically, the aforementioned essential components of an ADB system come from different manufacturers. Typically, a motor vehicle headlight system has an interface designed to input information provided by the ambient recording device. This means, for example, that a motor vehicle headlight manufacturer is dependent on the information provided by an externally provided, for example, purchased, ambient recording device when setting dimming scenarios. This information is often available in the form of so-called object lists.The environment recording device generates such object lists, for example, by using the aforementioned camera system to capture images in the field of view of the camera system, with the field of view preferably being adapted to the relevant area in front of the motor vehicle, and evaluating these images using a computing unit present in the environment recording device. Adapting the field of view to the relevant area means that the field of view has an aperture angle that is sufficiently large to capture at least the roadway in front of the motor vehicle. The computing unit delivers the aforementioned object lists as output. Objects in such lists can include vehicles such as trucks, cars, motorcycles, etc. Each individual object is typically assigned coordinates in the coordinate system of the camera system.This origin coordinate system therefore often has its origin approximately at the rear side of the rearview mirror in the interior of the motor vehicle, since a camera of the camera system is usually located there.

[0006] When the control system receives such an object list as input, it calculates a light image to be generated based on the object list. First, the coordinates of the objects must be converted into a coordinate system of the vehicle headlights. This requires relatively high computing power, causes significant time delays, and is a potential source of error. Furthermore, additional errors often arise from misidentification of the objects by the processing unit of the environment recording device. A not uncommon error of this type is confusion between a truck driving ahead and two motorcycles - the processing unit recognizes the taillights of a truck based on a first image, but in a second image, for example, the same taillights are interpreted as two motorcycles.Since the control system of the vehicle's headlight system cannot influence this data, a periodic flashing and dimming of the area between the taillights may occur, depending on whether the taillights are assigned to the two motorcycles (flashing) or the truck (dimming) in the object list. This may potentially result in dazzling the driver due to light reflection.

[0007] Furthermore, it may be the case that, for example, an oncoming multi-lane motor vehicle, typically with two spaced-apart headlights, is perceived by the sensor unit as merely two independent light sources, with two sensor pixels of the light sensor being "activated" due to a definable luminous flux threshold being exceeded, with one sensor pixel located between these two activated sensor pixels that has not been activated. The control unit would simply be prompted to reduce the luminous flux of the light pixel groups assigned to the two "activated" sensor pixels, thereby dazzling a driver of the oncoming vehicle.

[0008] WO 02 / 04247 A1, US 2020 / 055440 A2, EP 1 553 429 A1, DE 10 2011 006554 A1, DE 10 2007 040042 A1 and EP 2 380 774 A1 show lighting devices from the prior art.

[0009] It is an object of the invention to provide an improved lighting device.

[0010] This object is achieved in that the light generating unit, the light sensor device and the control unit are arranged together on a base support and together with the base support form a structural unit, wherein the luminous pixels of the luminous pixel array are divided into several luminous pixel groups, wherein each luminous pixel group can generate a segment of the segmented light distribution in a luminous solid angle, wherein each luminous pixel group comprises at least one luminous pixel, and wherein each sensor pixel of the plurality of first sensor pixels can detect light in a detection solid angle assigned to the respective sensor pixel and is each assigned to a luminous pixel group, wherein each sensor pixel of the plurality of first sensor pixels is assigned a different detection solid angle, wherein the detection solid angles are substantially adjacent to one another and form an overall detection solid angle in which light from the light-emitting object can be detected, and wherein the light incident on each first sensor pixel can be detected as the luminous flux value assigned to the respective first sensor pixel,wherein the detection solid angle detectable by a first sensor pixel is substantially identical to the illumination solid angle of the respectively assigned illumination pixel group, wherein the illumination device for measuring the distance of an object present in front of the illumination device has a laser beam generating device which is configured to emit at least one laser beam in a wavelength range from 780 nm to 1 mm in front of the illumination device and to change its horizontal orientation, wherein the light sensor device additionally comprises a second light sensor, which second light sensor comprises a plurality of second sensor pixels which are arranged in a row, wherein the second sensor pixels are configured to detect luminous flux in the wavelength range of the laser beam of the laser beam generating unit from light incident on the second light sensor, and wherein the control unit is configuredto compare the luminous flux values ​​detected by the respective first sensor pixels individually with a respectively definable threshold value and to reduce the luminous flux of the corresponding light pixel groups if the threshold value is exceeded, wherein in the event that an exceeding of the threshold value is detected in two first detection solid angles and no exceeding of the threshold value is detected in at least one detection solid angle between these two detection solid angles, the control unit is configured to derive a presumed object width which corresponds to the number of first sensor pixels, which is composed of the two detection solid angles at which the threshold value is exceeded and the detection solid angles lying between these two detection solid angles, and to compare it with an actual object width,which actual object width can be determined by means of a time-of-flight measurement of the laser beam reflected by the object by the second light sensor, wherein if the presumed object width corresponds to the actual object width, the control device is configured to reduce the luminous flux of the corresponding light pixel groups assigned to the first sensor pixels of the presumed object width, despite a failure to exceed the threshold value in the detection solid angles between the detection solid angles at which the threshold value is exceeded, and / or in the event that an exceedance of the threshold value is detected in a detection solid angle, the control unit is configured to derive a presumed object width corresponding to the first sensor pixel at which the threshold value is exceeded and to compare it with an actual object width,which actual object width can be determined by means of a time-of-flight measurement and / or triangulation measurement of the laser beam reflected by the object by the second light sensor, wherein the actual object width corresponds to the number of second sensor pixels at which light of the laser beam reflected by the object is detected, wherein if the actual object width is greater than the presumed object width, the control device is configured to reduce the luminous flux of those light pixel groups which correspond to the first sensor pixel at which the threshold value was exceeded and to those first sensor pixels whose detection solid angle is immediately adjacent to the detection solid angle at which an exceeding of the threshold value was determined, or the first sensor pixels which correspond to the second sensor pixels at which the actual object width was determined.

[0011] In triangulation measurement, the distance between the laser beam generation unit and the individual second sensor pixels of the second light sensor is known, and the angle at which the laser beam is emitted in its at least one line is also known and can be determined or retrieved by the control unit. Furthermore, the angle of the laser beam reflected from the object can also be detected, for example, by the corresponding second sensor pixel of the second light sensor, and is thus known. The control unit can determine or calculate the distance of the area of ​​the object to which the laser beam is directed and reflected.

[0012] It should be noted that the actual object width can correspond to the number of second sensor pixels at which light from the laser beam reflected off the object is detected. The second sensor pixels correspond to the first sensor pixels, with the number of first and second sensor pixels being the same, and each first sensor pixel being assigned exactly one second sensor pixel. Consequently, each second sensor pixel is also assigned the corresponding light pixel group of the corresponding first sensor pixel.

[0013] This also makes it possible to determine or derive the actual object width or object size of the object in front of the lighting device, since the laser beam, which can be changed in horizontal orientation, scans or samples several points of the object, whereby the object width or object size can be determined.

It should be noted that in this case, the light sensor, the light source, and the control unit are also arranged on the base support but are not in contact with it.

[0017] A particularly advantageous variant is obtained when several sensor pixels are grouped in the form of an "Active Pixel Sensor" (APS-CMOS) manufactured in CMOS technology, whereby some peripheral circuits for the function of the photodiode (A / D conversion, clocking of the readout, amplification) are implemented directly on the same semiconductor component.

[0018] In a particularly advantageous variant, it can be provided that one, in particular each, light pixel is designed as at least one LED light source.
