Abstract
A method for adjusting an automated headlight system of a motor vehicle, the headlight system having headlights for generating a low beam and a control device for adjusting a lower cut-off line of the low beam, involves calculating an elevation gradient from an extract from a digital elevation model, determining, from the elevation gradient, two turning points which are nearest ahead, determining and characterizing a mean path position on the basis of the turning points, and adjusting the lower cut-off line to a central point of the mean path position at least when the first turning point is reached.
Claims10
A method for adjusting an automated headlight system of a motor vehicle, wherein the headlight system has at least two headlights that generate a low beam and a control device configured to adjust a lower cut-off line of the low beam, the method comprising the following steps in the following order:
- A. calculating an elevation gradient of a route ahead of the motor vehicle from an extract from a digital elevation model;
- B. determining, from the calculated elevation gradient, two turning points that are nearest ahead and leading the motor vehicle to tip around a y axis of the motor vehicle;
- C. determining and characterizing a mean path position based on the two turning points nearest ahead;
- and
- D. adjusting the lower cut-off line of the low beam of the headlight system to a central point of the mean path position at least when the vehicle reaches a first one of the two turning points nearest ahead.
An automated headlight system for a motor vehicle, wherein the automated headlight system comprises:
- at least two headlights configured to generate a low beam;
- and
- a control device configured to adjust a lower cut-off line of the low beam,
- wherein the automated headlight system is configured to
- first calculate an elevation gradient of a route ahead of the motor vehicle from an extract from a digital elevation model;
- second determine, from the calculated elevation gradient, two turning points that are nearest ahead and leading the motor vehicle to tip around a y axis of the motor vehicle;
- third determine and characterize a mean path position based on the two turning points nearest ahead;
- and
- fourth adjust the lower cut-off line of the low beam of the headlight system to a central point of the mean path position at least when the vehicle reaches a first one of the two turning points nearest ahead.
