[0002] Control device, system and method for generating a glare-free high beam of a vehicle

[0003] The present disclosure generally relates to methods for controlling headlights. More specifically, the present disclosure relates to a control device, a system, and a method for generating a glare-free high beam using a headlight system of a vehicle.

[0004] Vehicle headlights, in particular those with segmented high beams, are known for generating glare-free high beams. If, for example, road users are detected in the high beam area of ​​the headlight light field using the vehicle's sensors, certain segments of the headlight can be deactivated to generate one or more shadow areas to reduce glare for the detected road users. Due to system tolerances and / or system latencies or detection methods, a road user may not be completely glared by the shadow areas in the headlight high beam. To ensure reliable glare control, especially despite system tolerances and system latencies, the shadow areas are designed to be extra large or with a reserve, which can impair the overall performance of the headlights.

[0005] An object of the embodiments of the present disclosure is to provide a control device, a system and a method for generating a glare-free high beam, which enable both reliable glare control and high headlight performance.

[0006] To achieve this object, according to a first aspect, a control device for generating a glare-free high beam using a headlight system of a vehicle is provided. The headlight system can be designed, in particular, as a matrix headlight for generating a segmented high beam. The control device comprises a processor, a memory unit for storing data and machine-readable instructions for the processor, and an interface.

[0007] The interface is designed to receive sensor data from a sensor system for detecting another vehicle, object, or road user exposed to the risk of glare from the headlight system, in particular a preceding and / or oncoming vehicle. The sensor system can, in particular, comprise one or more cameras and be designed to detect other vehicles, in particular based on their headlights or taillights. The interface is further designed to output control signals or control commands for controlling the headlight system.

[0008] The memory unit contains the instructions for the processor to evaluate the data received from the sensors to determine the current positioning of a detected vehicle. In this context, positioning refers to both a position or location as well as an orientation of the detected vehicle. The position and orientation can be determined, in particular, in a coordinate system or sensor coordinate system linked to the detecting vehicle, i.e., the vehicle equipped with the control device and the sensors, or the ego vehicle.

[0009] The memory unit further contains instructions for the processor to determine, based on the current positioning of the detected vehicle, a base width of a shadow area in a headlight high beam field required to avoid direct glare of the detected vehicle. The width of a shadow area in the headlight high beam can be specified or defined, in particular, in angular coordinates, in particular by a horizontal opening angle of the corresponding high beam shadow in the headlight high beam field.

[0010] The memory unit further contains instructions for the processor to determine at least one offset or a horizontal offset angle for expanding the shadow area to avoid lateral glare, in particular lateral mirror glare and / or lateral window glare, of the detected vehicle, and to control the headlight system such that a shadow area is created in the headlight high beam field to avoid glare of the detected vehicle, the width of which shadow area substantially corresponds to the base width increased by the at least one offset.

[0011] The width of the resulting shadow area is thus composed of the base width and the offset. Depending on the positioning of the detected vehicle, particularly in the sensor coordinate system, the proportion of the offset in the overall width of the resulting shadow area can vary. For example, if a vehicle detected by the sensor is driving directly in front of the ego vehicle, the risk of side glare is reduced and at least one offset can be minimized. Shadow areas of a glare-free high beam can thus be better adapted to the correct size depending on the situation, so that other road users are not disturbed by mirror glare, for example, without having to make the shadow areas fundamentally larger.

[0012] By determining the offset and extending the base width by the determined offset, the width of the resulting shadow area can be automatically adjusted to the required minimum size, thus avoiding unnecessarily large shadow areas.

[0013] The memory unit can contain instructions for the processor to determine the current positioning of the detected vehicle based on a current distance or object distance and a current azimuth angle or object angle. The distance can be specified, in particular, as the distance between the geometric center of the detected vehicle and the zero point of the sensor's coordinate system. The azimuth angle can be specified, in particular, as a horizontal angle with respect to a zero axis in the sensor's coordinate system, directed along the direction of travel. The positioning of the detected vehicle can be easily described based on the distance and the azimuth angle, in particular with respect to the sensor's coordinate system.

[0014] A look-up table can be stored in the memory unit, which establishes a relationship between the position of the detected vehicle and the offset. Using this stored relationship, required offsets can be determined in real time based on the current distance and the current azimuth angle.

[0015] The offset values ​​in the look-up table can be stored with the proviso that, when the vehicle detected by the sensor system is tilted, window areas of the detected vehicle, in particular a side facing the sensor system or the camera, are essentially completely covered by the at least one offset or lie within the offset range. Due to the essentially complete coverage of the window areas of the vehicle by the offset, lateral glare of the detected vehicle or its occupants can be reliably avoided.

[0016] In some embodiments, offsets on both sides are stored in the look-up table in a small-angle range to prevent side mirror glare. For example, the side mirrors of a vehicle traveling ahead can be detected at an azimuth angle of approximately 0° using a left offset and a right offset, so that no side mirror glare from the detected vehicle can occur due to the high beam headlights.

[0017] In some embodiments, the memory unit contains instructions for the processor to determine the positioning of the detected vehicle, the base width, and the offset for a left headlight and a right headlight of the headlight system separately, in particular in the respective headlight coordinate system, and to control the left headlight and the right headlight accordingly. By separately determining the base width and offset and by separately controlling the two headlights, the shadow area for glare control of the detected vehicle can be defined more precisely.

[0018] According to a second aspect, a system with a headlight system of a vehicle for generating a glare-free high beam is provided. The system comprises a control device according to the first aspect and a sensor system for detecting another vehicle exposed to a risk of glare from the headlight system. The sensor system can comprise one or more cameras and be configured to detect other vehicles, in particular based on their headlights or taillights. This sensor system and the headlight system are functionally connected to the control device via the interface.The memory unit contains instructions for the processor to evaluate the sensor data received from the sensor system to determine a current positioning of the detected vehicle and, based on the current positioning of the detected vehicle, to determine a base width of a shadow area in a headlight high beam field required to avoid direct glare of the detected vehicle. The memory unit further contains instructions for the processor to determine at least one offset for expanding the shadow area to avoid lateral glare of the detected vehicle. The memory unit also contains instructions for the processor to control the headlight system such that a shadow area is created in the headlight high beam field to avoid glare of the detected vehicle, the width of which shadow area essentially corresponds to the base width increased by the at least one offset.

[0019] By determining the at least one offset and by extending the base width by the determined at least one offset, the width of the resulting shadow area can be automatically adjusted to the required minimum size, thereby avoiding unnecessarily large shadow areas.

[0020] The headlight system may comprise a left and a right headlight, and the memory unit may contain instructions for the processor to determine the positioning of the detected vehicle, the base width, and the offset for each of the headlights separately, in particular in the respective headlight coordinate system, and to control the left headlight and the right headlight accordingly.

[0021] By determining the base width and offset separately and by controlling the two headlights separately, the shadow area for glaring the detected vehicle can be defined more precisely, so that the impairment of headlight performance caused by unnecessarily large shadow areas can be further reduced.

[0022] According to a third aspect, a method for generating a glare-free high beam by means of a headlight system of a vehicle is proposed. The method can be carried out in particular by means of a control device according to the first aspect or by means of a system according to the second aspect. The method comprises providing sensor data, in particular by means of a sensor system, for detecting another vehicle exposed to a risk of glare by the headlight system of the vehicle and evaluating the sensor data to determine a current positioning of a detected vehicle. The method further comprises determining a base width of a shadow area required to avoid direct glare of the detected vehicle, in particular based on the current positioning of the detected vehicle.The method also includes determining at least one offset for expanding the shadow area to avoid lateral glare of the detected vehicle, in particular based on the current positioning of the detected vehicle, and controlling the headlight system such that a shadow area is created in the headlight high beam field to avoid glare of the detected vehicle, the width of which shadow area essentially corresponds to the base width increased by the at least one offset. By determining the at least one offset and by expanding the base width by the determined at least one offset, the width of the resulting shadow area can be automatically adjusted to the required minimum size, thereby avoiding unnecessarily large shadow areas.

[0023] According to a fourth aspect, a vehicle is provided. A system with a headlight system according to the second aspect is implemented in the vehicle. The vehicle is characterized by reliable glare control for road users and improved headlight performance.

[0024] The invention will now be explained in more detail with reference to the accompanying figures. The same reference numerals are used throughout the figures for identical or equivalent parts.

[0025] Fig. 1 shows a schematic block diagram of a system with a headlight system for generating a glare-free high beam according to an embodiment,

[0026] Fig. 2 shows schematically a traffic situation with a vehicle according to an embodiment,

[0027] Fig. 3 shows schematically a traffic situation with a vehicle according to another embodiment, and

[0028] Fig. 4 shows a flowchart of a method for generating a glare-free high beam according to an embodiment.

[0029] Fig. 1 shows a schematic block diagram of a system with a headlight system for generating a glare-free high beam according to one exemplary embodiment. The system 1 comprises a sensor system 2 or vehicle sensor system, a control device 3, and a headlight system 4.

[0030] The sensor system 2 is designed to detect a current traffic situation with regard to the risk of glare to other road users. In particular, the sensor system 2 is designed to detect a vehicle exposed to a risk of glare by the headlight system 4, for example a vehicle traveling ahead or an oncoming vehicle. The headlight system 4 is a headlight system suitable for generating a glare-free high beam. The headlight system 4 can in particular comprise one or more headlight modules, in particular high beam modules for generating a segmented high beam. The headlight modules can in particular be designed as LED modules with a number of LEDs for each illuminating a high beam segment in the headlight high beam field. The LEDs can in particular be arranged in a matrix or pixel-like manner on one or more substrates, in particular metal-core circuit boards.An LED module can, in particular, comprise an LED pixel array with a sufficient number or packing density of LED pixels to achieve high-resolution, glare-free functionality. The headlight system 4 can, in particular, comprise headlight optics for shaping the respective LED light into a respective partial light beam for illuminating a respective partial area of ​​a headlight beam cone.

[0031] The control device 3 comprises a processor 10 and a memory unit 20 for storing data and machine-readable instructions for the processor 10. The control device 3 further comprises an interface 30. The interface 30 is functionally connected to the sensor system 2 for receiving sensor data and to the headlight system 4 for controlling the headlight system 4. The control device 3 can, in particular, comprise one or more processors. The control device 3 or the processor 10 can, in particular, be designed as a separate unit and / or as part of a vehicle control unit or implemented in the vehicle control unit.

[0032] The sensor system 2 can, in particular, comprise one or more cameras that can be arranged at different locations on and / or in the vehicle and can be designed to detect the vehicle surroundings with regard to vehicles exposed to the risk of glare. The sensor system can comprise one or more sensors or real-time observation devices or image acquisition systems, such as optical sensors, cameras, radar and / or lidar sensors. The sensor system 2 can, in particular, be designed as part of an ADAS (advanced driver assistance system) sensor system of the vehicle. With additional detection methods, such as lidar, complete vehicle contours can be detected even over greater distances. For cost reasons, particularly in the compact and small vehicle segments, the system will be limited to camera information about the taillights or headlights of the detected vehicles without sensor redundancy.The memory unit 20 can contain instructions for the processor 10 to evaluate the sensor data generated by the sensor system 2 to determine a current positioning of the detected vehicle and, based on the current positioning of the detected vehicle, to determine a base width of a shadow area in a headlight high beam field required to avoid direct glare of the detected vehicle. The memory unit 20 can further contain instructions for the processor 10 to determine at least one offset for expanding the shadow area to avoid lateral glare of the detected vehicle. Lateral glare of the vehicle detected by the sensor system 2 or its occupants can occur in particular via side mirrors and / or via side windows of the detected vehicle.

[0033] The control unit 20 can also contain instructions for the processor 10 to control the headlight system 4 such that a shadow area is created in the headlight high beam field to de-glare the detected vehicle, the width of which shadow area essentially corresponds to the base width increased by the at least one offset.

[0034] The memory unit 20 can contain instructions for the processor 10 to detect the current positioning of the detected vehicle based on a current distance and a current azimuth angle. In particular, the positioning of the detected vehicle can be detected in a polar coordinate system fixed to the sensor system 2 or to at least one camera of the sensor system. The distance can be defined, in particular, as the distance between the zero point of the coordinate system and the geometric center of the detected vehicle. The azimuth angle can be defined, in particular, as a horizontal angle with respect to a zero-angle ray directed along the direction of travel.

[0035] A look-up table can be stored in the memory unit, establishing a relationship between the position of the detected vehicle and the required offset. Using this stored relationship, the required offsets can be quickly and easily determined in real time based on the current distance and the current azimuth angle.

[0036] The offset values ​​can be stored in the look-up table with the proviso that, when the vehicle detected by sensor system 2 is tilted, particularly with respect to the zero-angle beam, window areas of the detected vehicle are essentially completely covered by the at least one offset. This can reliably prevent lateral glare of the detected vehicle or its occupants.

[0037] In the look-up table, a bilateral offset can be stored in a small-angle range, particularly for glare-reducing the exterior mirrors of a vehicle driving ahead. A small-angle range can be defined as an azimuth angle range between -5° and +5°, particularly between -2° and +2°. In the small-angle range, for example, at an azimuth angle between -1° and +1°, the side mirrors of the vehicle driving ahead can be detected using a generally distance-dependent left and right offset, so that the side mirrors of the detected vehicle cannot be dazzled by the high beam headlights.

[0038] In some embodiments, the headlight system 4 comprises independently controllable headlights, in particular a left headlight and a right headlight. The memory unit 20 can also contain instructions for the processor 10 to determine the base width and offset separately for the left headlight and for the right headlight, in particular in the respective headlight coordinate system, and to control the left headlight and the right headlight accordingly.

[0039] Fig. 2 schematically shows a traffic situation with a vehicle according to an embodiment. In particular, Fig. 2 shows a schematic top view of a vehicle 50 with a system 1 according to the first aspect. In the traffic situation shown, the vehicle 50 is traveling essentially in a straight line on a wide road behind other vehicles 60 detected by the sensor system 2. Fig. 2 further shows a coordinate system fixed to the vehicle 50 or to the sensor system 2, in particular to a front camera of the vehicle, with a zero point C, an X-axis, and a Y-axis. The azimuth angle 0 of the respective other vehicle 60 or vehicle detected by the sensor system 2 is plotted with respect to a zero axis 70 on the X-axis. The zero axis 70 corresponds to a horizontal sensor angle of 0° and essentially corresponds to the axis of symmetry of the vehicle 50. The distance L between the vehicle 50 and the respective other vehicle 60 is plotted on the Y-axis.2 further shows offset areas 80 associated with the detected vehicles 60. To simplify the illustration, the base width or the base area are not shown in Fig. 2 to avoid direct glare of the vehicles 60.

[0040] As can be seen from Fig. 2, the size of the offset range or the offset angle Q depends on the current positioning of the detected vehicle 60. In general, the larger the azimuth angle 0 or the absolute value of the azimuth angle 0 and the smaller the distance L, the larger the offset or offset angle Q.

[0041] In some embodiments, offsets are defined for both sides in the low-angle range, such as the vehicle 60 shown in the middle of the road. The shadow area is extended from both sides to avoid side mirror glare of the detected vehicle 60.

[0042] Fig. 3 schematically shows a traffic situation with a vehicle according to another exemplary embodiment. In the traffic situation shown in Fig. 3, another vehicle 60 is traveling ahead of the vehicle 50 having the system 1, slightly offset to the right. The sensor system 2 of the vehicle 50 detects the preceding vehicle 60, similarly as explained in Fig. 2. In the exemplary embodiment shown, the vehicle 50 has a headlight system 4 with separately controllable headlights. The memory unit 20 of the control device 3 contains instructions for the processor 10 to calculate the base width (not shown) and the offsets or offset angles Q', Q" separately for the left headlight and for the right headlight, and to control the left headlight and the right headlight accordingly.

[0043] As illustrated in Fig. 3, the offset angles Q', Q" can differ considerably from the perspective of the left headlight and the right headlight. By considering the two headlights individually, the precision of glare control can be further increased, so that unnecessarily large shadow areas in the headlight field can be avoided or reduced.

[0044] Fig. 4 shows a flowchart of a method for generating a glare-free high beam according to one exemplary embodiment. The method 300 can be carried out in particular on a vehicle 50 equipped with the system 1 according to Fig. 1. According to the method 300, in a method step 400, sensor data for detecting a signal transmitted by the headlight system 4 of the vehicle 50 is provided. For example, other road users or traffic objects can be detected by means of a front camera of the vehicle 50, in particular based on the rear lights or headlights detected by the front camera. A front camera can in particular be designed such that the detection of the other road users, in particular their position or orientation, can take place with sufficient precision and reliability.

[0045] In a method step 500, the sensor data are evaluated to determine the current positioning of an object or vehicle 60 detected by the sensor system 2. The location of the detected object can be unambiguously determined via the distance L between the sensor system or the front camera and the object and via the angular position or the azimuth angle 0 relative to the zero direction or 0° sensor angle.

[0046] In a method step 600, a base width of a shadow area required to avoid direct glare of the detected vehicle 60 is determined. Direct glare is understood here as glare of occupants of the vehicle 60 detected by the sensor system 2, which occurs essentially via a windshield and / or rear window of the detected vehicle 60. The base width can be determined in particular based on the headlights or taillights of the vehicle to be dispatched, as detected by the sensor system 2. The base width can in particular be dimensioned such that a shadow area with a base width essentially completely covers the rear or front part of the detected vehicle 60.

[0047] In a method step 700, at least one offset is determined to expand the shadow area to avoid lateral glare of the detected vehicle 60. Lateral glare can occur in particular when the occupants of the detected vehicle 60 are glared via the side mirrors and / or through the side windows. The at least one offset can in particular be dimensioned such that a side of the vehicle 60 to be glared that is exposed to the headlight high beam is essentially completely covered by the at least one offset. Thus, the vehicle to be glared can be masked not only in the area of ​​the lamps or headlights, but also in areas where there is a risk of lateral glare, in particular in the window area and / or in the area of ​​the exterior mirrors. The at least one offset can in particular be determined using a look-up table orA conversion table is used, where the distance L and the azimuth angle 0 are used as input for the conversion table. In particular, the table can contain an X-axis or row with the values ​​of the azimuth angle 0, and a Y-axis or column with the values ​​of the distance L to the detected object. For each angle or distance value, a geometric angle component or offset angle Q is stored for the right and left sides of the object or vehicle.

[0048] In a method step 800, the headlight system 4 is controlled by the control device 3. A shadow area is formed in the headlight high beam to reduce glare for the detected vehicle 60, with a horizontal width that essentially corresponds to the base width increased by at least one offset. For each angle-distance pair, the corresponding geometric component or offset can be taken from the table in order to add it to the right or left side of the base area if necessary. Intermediate values ​​can also be applied by interpolation so that the light image is adjusted smoothly and not in steps with sufficient resolution.

[0049] The resulting shadow area thus comprises both the base area and the required offset area, so that the detected vehicle 60 is protected from both direct glare and lateral glare. In particular, the method enables automatic adjustment of the base width and the offset according to the respective driving situation, so that an excessively wide shadow area can be avoided. By adding the offset to the base width, a two-dimensional adaptive geometric component is automatically added, depending on the current object distance and object angle. An object in the range of the high-beam illumination can be masked more precisely by applying the described offset using a sufficiently large, precisely measured shadow area.

[0050] In some embodiments, in method steps 600 and 700, the base width and the offset are determined separately for each headlight of the headlight system, so that each headlight can be controlled individually to set the respective base width and the respective offset. By separately determining the base width and the offset and by separately controlling the two headlights, the shadow area for glaring the detected vehicle can be defined more precisely, so that the impairment of headlight performance caused by unnecessarily large shadow areas can be further reduced. The system and method described above enables the potential of high-resolution headlight modules to be better utilized. This is because the resolution of light modules, particularly matrix headlights, is becoming increasingly higher, so that a shadow area can be mapped very sharply and in detail using hardware.By automatically adding the adaptive or situation-dependent offset to the likewise situation-dependent base width of the headlight shadow, the technical possibilities of high-resolution headlights can be better exploited and unnecessary shadow areas can be further reduced.

[0051] Although at least one exemplary embodiment has been shown in the foregoing description, various changes and modifications may be made. The recited embodiments are merely examples and are not intended to limit the scope, applicability, or configuration of the present disclosure in any way. Rather, the foregoing description provides those skilled in the art with a road map for implementing at least one exemplary embodiment; numerous changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the appended claims and their legal equivalents. Furthermore, multiple modules or multiple products may be connected together in accordance with the principles described herein to obtain additional functions.
