Example Embodiment

[0035] figure 1 A plan view of a motor vehicle 2 is shown, which has a proposed (framed in dashed line) headlight system 4.

[0036] The headlight system 4 has two headlights 6, 8 which are designed to illuminate the road section in front of the motor vehicle 2. The headlights 6, 8 are matrix headlights and include a plurality of headlight elements 6.1, 6.2, 6.3, 6.4 and 8.1, 8.2, 8.3, and 8.4. The matrix headlight elements 6.1 to 6.4 and 8.1 to 8.4 are used to achieve different light distributions, and for this purpose, the matrix headlight elements 6.1 to 6.4 and 8.1 to 8.4 are controlled accordingly and dimmed accordingly.

[0037] In addition, the headlight or matrix headlight elements 6.1 to 6.4 and 8.1 to 8.4 can also be adjusted along their orientation. For this reason, the headlamps 6, 8 are designed with headlamp adjusting devices 6.6 and 8.6. Additionally or alternatively in some embodiments, the radiation optics can be changed.

[0038] In order to control the headlight...

Abstract

The invention relates to an operation method for at least one head light (6,8) of a motor vehicle (2). The at least one head light (6,8)is controled by head light control equipment (10). The head light control equipment is designed to adjust light distribution of the at least one head light light (6,8) according to driving parameters; light distribution can be identified during highway driving and adjusted when the at least one head light (6,8) is provided with a far-light lamp, so light toward lights (6,8) on an opposite road (24r) can be reduced via maximum possible illumination degree (30) of the opposite road.

Description

technical field [0001] The invention relates to a method for operating a headlight of a motor vehicle, a headlight system of a motor vehicle and a motor vehicle with a headlight system. Background technique [0002] It is known that motor vehicles have headlight systems for illuminating the road ahead of the motor vehicle. It is also known that most motor vehicles have a headlight system which can realize at least one two-stage lighting, dipped beam and high beam. In this case, the high-beam headlights are generally significantly brighter than the low-beam headlights and illuminate significantly further. However, the light cone of the high beam can also cover oncoming vehicles, which can dazzle the driver of the oncoming vehicle. [0003] From DE 10 2008 060 949 A1 a method is known for controlling vehicle headlights which each have an adjustable light distribution for ambient lighting of a motor vehicle, wherein the environment in front of the vehicle is recorded and eval...
