Embodiment Construction

[0028] figure 1 The illustrated illumination intensity distribution shows the illumination intensity in a plane E perpendicular to the vehicle longitudinal direction I of the first vehicle 1 . exist figure 1 The different lighting intensities are shown by isolux curves. The vehicle longitudinal direction I of the first vehicle 1 intersects the plane at a point U. In this point U is set the origin of a coordinate system which can be used to describe the distribution of the illumination intensity of the main headlights of the first vehicle 1 and which can be used in figure 1 is shown in .

[0029] In addition, in figure 1 A second vehicle 2 is shown in , the driver of which is not allowed to be dazzled by the main headlights of the first vehicle. The position of the second vehicle 2 is described by the plane angle α, the elevation angle β and the distance e, wherein the plane angle α is measured from a vertical plane containing the longitudinal direction I of the vehicle to...

Abstract

The invention relates to a control device for controlling main headlights of a vehicle having an adjustable light distribution and an adjustable vertical light-dark limit in at least one light distribution, comprising an input for reading in information about the vehicle An object ahead that is to be protected from glare; a processing device with which, on the basis of the read-in information, adjustment parameters and parameters for adjusting the light distribution that can be adjusted on the right and / or left main headlights can be generated / Or from the read-in information, the processing device can generate a vertical light-dark limit for adjusting the adjusted light distribution on the right-hand main headlight and a vertical light-dark limit for the adjusted light distribution on the left-hand main headlight. Parameters of the vertical light-dark limit; the output terminal can provide adjustment parameters for adjusting the light distribution and / or the vertical light-dark limit, wherein the control device has a memory in which the position in front of the main headlight is stored for the energy The illumination intensity of the light distribution of the main headlights is adjusted by the control unit.

Description

technical field [0001] The invention relates to a control device for controlling main headlights of a vehicle having an adjustable light distribution and an adjustable vertical light-dark limit in at least one light distribution, comprising: [0002] - an input for reading in information about the position of objects to be prevented from being dazzled in front of the vehicle, in particular of vehicles driving ahead and / or oncoming vehicles; [0003] - processing device, [0004] On the basis of the read-in information, control parameters and / or control parameters for setting the adjustable light distribution at the right-hand and / or left-hand main headlight can be generated by means of the processing device. [0005] Based on the read-in information, the processing unit can generate a vertical light-dark limit for adjusting the adjusted light distribution at the right main headlight and a vertical light-dark limit for the adjusted light distribution at the left main headlight...
