Method for controlling a headlamp of a motor vehicle
A method is provided for controlling a headlamp of a motor vehicle. An object is detected by an object detecting device of the motor vehicle. An angle is determined between a geometrical longitudinal axis of the motor vehicle passing through the object detecting device and a geometrical connecting line between the object detecting device and the object. A glare reduction range of the headlamp is determined using the angle without taking into account a total distance between the object and the motor vehicle, the headlamp illuminating the glare reduction range with a lower brightness than areas adjacent to the glare reduction range.
1. A method for controlling a headlamp of a motor vehicle, the method comprising the following steps:
detecting an object by an object detecting device of the motor vehicle;
determining an angle between a geometrical longitudinal axis of the motor vehicle, the geometrical longitudinal axis defined by a line passing through the object detecting device and oriented parallel with respect to a direction of motion of the motor vehicle, and a geometrical connecting line between the object detecting device and the object;
determining a glare reduction range of the headlamp using the angle without taking into account a total distance between the object and the motor vehicle, the headlamp illuminating the glare reduction range with a lower brightness than areas adjacent to the glare reduction range.
2. The method according to claim 1 , wherein the angle and a correction value are used for determining the glare reduction range.
3. The method according to claim 2 , wherein the correction value depends on the angle.
4. The method according to claim 2 , wherein the correction value is independent of the total distance between the object and the motor vehicle.
5. The method according to claim 1 , wherein the angle is a horizontal angle.
6. The method according to claim 1 , wherein the glare reduction range is U-shaped.
7. The method according to claim 1 , wherein a width of the glare reduction range depends on the angle.
8. The method according to claim 1 , wherein the geometrical longitudinal axis is located between the headlamp and the object and in that, when determining the glare reduction range, exclusively an end region of the headlamp facing the geometrical longitudinal axis is taken into account.
9. The method according to claim 1 , wherein the geometrical connecting line passes between the object detecting device and an outer edge of the object.
10. The method according to claim 9 , wherein the outer edge of the object is the outer edge that is furthest away from the geometrical longitudinal axis.
11. A motor vehicle comprising:
a headlamp,
an object detecting device for detecting an object, and
a determination unit determining an angle between a geometrical longitudinal axis of the motor vehicle, the geometrical longitudinal axis defined by a line passing through the object detecting device and oriented parallel with respect to a direction of motion of the motor vehicle, and a geometrical connecting line between the object detecting device and the object, and
wherein the determination unit determines a glare reduction range of the headlamp using the angle without taking into account a total distance between the object and the motor vehicle,
wherein the headlamp is adapted to illuminate the glare reduction range with a lower brightness than areas adjacent to the glare reduction range.
12. The motor vehicle according to claim 11 , wherein the object detecting device transmits image data to the determination unit, the image data including image data of the object and a surrounding of the object, wherein the determination unit determines the angle by using the image data.
