Problems solved by technology

[0004] However, when driving on a highway section with a large number of intermediate guardrails, the recognition of the surrounding environment may fail, resulting in the inability to recognize oncoming vehicles
In this case, according to the prior art, it can happen that the high-beam light distribution or parts of the high-beam light distribution cannot be adapted, which can cause blinding to oncoming traffic

Embodiment Construction

[0035] figure 1 A plan view of a motor vehicle 2 with a proposed headlight system 4 (outlined by dashed lines) is shown.

[0036] The headlight system 4 has two headlights 6 , 8 which are designed to illuminate the road ahead of the motor vehicle 2 . The headlights 6, 8 are matrix headlights and comprise 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 serve to achieve different light distributions, for which purpose the matrix headlight elements 6.1 to 6.4 and 8.1 to 8.4 are correspondingly controlled and dimmed accordingly.

[0037] Furthermore, 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 purpose, the headlights 6, 8 are provided with headlight adjustment devices 6.6, 8.6. Additionally or alternatively in some embodiments, the radiation optics may be altered.

[0038] A headlight control device 10 is provid...

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...
