Embodiment Construction

[0041] figure 1 A schematic illustration of a motor vehicle 10 according to an exemplary embodiment of the invention is shown, which has two array headlights 12 designed as headlights, a front camera 16 arranged on the vehicle front 14 and a control device 18 . In this case, the control device 18 is coupled not only to the camera 16 but also to the corresponding headlight array 12 and is designed to adjust the position of the headlight array 12 relative to the camera 16 . In this case, the adjustment of the right and left array headlights 12 takes place in the same manner and is therefore explained below only with reference to the individual array headlights 12 .

[0042] Such an array headlamp 12 is schematically shown again in detail in figure 2 shown in . The array headlight 12 here has, for example, six segments S1 , S2 , S3 , S4 , S5 , S6 arranged in a row 20 extending along the y-axis of the illustrated motor vehicle coordinate system 22 , Wherein, the corresponding...

Abstract

The invention relates to a method for calibrating a position (24) of a matrix headlamp (12) of a motor vehicle by means of a camera (16) of the motor vehicle (10), wherein the matrix headlamp (12) comprises a plurality of segments (S1, S2, S3, S4, S5, S6) controllable independently of one another for light emission. At least one first image of a sign is recorded by means of the camera (16), a location area in which the sign (30) is located is determined, the illuminance of a first segment (S1, S2, S3, S4, S5, S6) is changed, at least one second image is recorded and examined in order to ascertain whether a change in a glare effect detected on the basis of the recorded at least one second image has occurred, and, if so, the position (24) of the matrix headlamp (12) is calibrated in accordance with the first segment (S1, S2, S3, S4, S5, S6) and position information (KL, KR) derived from the location region.

Description

technical field [0001] The invention relates to a method for adjusting the position of a headlight array of a motor vehicle by means of a camera of the motor vehicle, the headlight array having a plurality of fields for light radiation which can be actuated independently of one another part. The invention also includes a control device for a motor vehicle and a motor vehicle. Background technique [0002] Array headlights for motor vehicles are known from the prior art. These array headlights usually have a plurality of segments which are arranged in one row or also in several rows and which can each be actuated individually. In this case, the respective segment can include, for example, one or more LEDs. Furthermore, the corresponding segment can be switched on or off or also dimmed in any desired manner, depending on the situation or the light distribution to be provided. A particularly flexible and situationally adapted light distribution can thus be provided. For ex...
