Embodiment Construction

[0025] An exemplary embodiment for adjusting the light distribution of the headlights 3 of the first motor vehicle 1 is explained below with reference to the drawings in such a way that (in front of the first motor vehicle and at the same Driving in the opposite direction) the motor vehicle 2 ahead is not dazzled by the light distribution 12 of the headlights 3 .

[0026] figure 2 A flow chart illustrating a method of light distribution of a headlight 3 of a first motor vehicle 1 according to the invention is shown. In the present exemplary embodiment, the section that changes the direction of the road (that is, the section that deviates from the direction) is the hilltop 11 . The invention involves the steps of determining and storing the length 13 (also referred to as the driving distance) of the section of road between the preceding vehicle 2 and the following motor vehicle 1 , first passing the preceding vehicle 2 over the hilltop 11 , and thereafter following the follow...

Abstract

A method for adjusting a distribution of light from a headlight of a first motor vehicle in order to avoid the headlight blinding of dazzling a driver of a leading vehicle travelling ahead of and in the same direction as the first vehicle. The method includes: detecting a following distance between the vehicle and the leading vehicle on an initial road section; operating the headlight at a first illumination range less than or equal to the following distance; detecting a directionally-deviating road section ahead of and having a direction different from the initial road section; detecting thatthe leading vehicle has moved beyond a transition between the initial road section and the directionally-deviating road section; operating the headlight at a second illumination range not extending beyond the transition; and operating the headlight at the first illumination range after the vehicle reaches the transition.

Description

technical field [0001] The invention relates to a method for adjusting the light distribution of a headlight of a motor vehicle. Background technique [0002] The distribution of light from a headlamp (sometimes referred to as the beam pattern of the headlamp) is usually divided between a normal or "low beam" setting and a "high beam" setting in which the headlamp's The maximum lighting range is set at a relatively short distance (in order to avoid dazzle or dazzle the driver of oncoming traffic), at the "high beam" setting, where when oncoming traffic is insignificant, the maximum lighting range Set to a relatively long distance. In flat landscapes with long curves, low beams generally do not cause oncoming traffic to become dazzled. However, it may be necessary to adjust the high beams to a shorter illumination range accordingly, depending on vehicles driving ahead and oncoming traffic. [0003] As taught in US 7,364,333 B2, adjustment of the light distribution of the h...
