Method for adjusting the lighting range of a vehicle headlamp |
摘要 |
A method for adjusting the lighting range of a headlamp in a motor vehicle, is performed with the following steps. A first coordinateis acquired that corresponds to a position of the motor vehicle. At least one image of a camera connected with the motor vehicle is evaluated so as to acquire a second coordinate that corresponds to the position of an object on a roadway in the zone ahead of the motor vehicle. A reference angle is calculated for the motor vehicle from the first coordinate, the second coordinate and a height of the camera over the roadway. The lighting range of the headlamp is adjusted based on the reference angle. |

1. A method for adjusting the lighting range of a headlamp in a motor vehicle comprising:
acquiring first coordinate data that corresponds to a position of a motor vehicle; evaluating image data from a camera connected with the motor vehicle, so as to acquire second coordinate data that corresponds to the position of an object on a roadway in the zone ahead of the motor vehicle; calculating a reference angle for the motor vehicle from the first coordinate, the second coordinate and an installed height of the camera above the roadway; and adjusting a lighting range of a headlamp on the motor vehicle based on the reference angle, wherein calculating the reference angle is performed via triangulation. |
