Method for controlling a headlamp system for a vehicle, and headlamp system
First Claim
1. A computer-implemented method for controlling a headlamp system for a vehicle, the headlamp system having two headlamps set apart from each other, comprising:
- detecting, by a sensor, road users in front of the vehicle in a driving direction;
producing, by at least one of the two headlamps, a first total light pattern having an illumination range on a first side of a center axis is greater than on a second side of this center axis, and a second total light pattern having an illumination range in a direction of at least one detected road user that is less than a distance to the detected road user and an illumination range in another direction that is greater than the distance to the detected road user; and
during a switch from the first total light pattern to the second total light pattern, reducing the illumination range of at least one headlamp on the first side of the center axis to at least such an extent that it is less than the distance to the detected road user, the second total light pattern being produced subsequently;
wherein in the second total light pattern, a center region having a lower illumination range is formed in the direction of the detected road user, and side regions, which have a greater illumination range, are formed on both sides adjacent to the center region; and
wherein in the second total light pattern, the side regions each form a vertical light-dark cutoff to the center region.

Abstract
In a method for controlling a headlamp system for a vehicle, the headlamp system having two headlamps, set apart from each other, road users are detected in front of the vehicle in the driving direction, and a first total light pattern is able to be produced, in which the illumination range on a first side of a center axis is greater than on the other, second side of this center axis, and a second total light pattern is able to be produced, in which the total light pattern is controllable such that it has an illumination range in the direction of at least one detected road user that is less than the distance to the detected road user, and which has an illumination range in another direction that is greater than the distance to the detected road user. During the switch from the first total light pattern to the second total light pattern, the illumination range of at least one headlamp on the first side of the center axis is first reduced to at least such an extent that it is less than the distance to the detected road user, the second total light pattern being produced subsequently.

6. A headlamp system for a vehicle, comprising:
-
at least two headlamps set apart from each other and configured to generate a total light pattern; a sensor configured to detect road users in front of the vehicle in a driving direction; and a control unit, coupled to the sensor and configured to transmit signals to control the headlamps to produce a first total light pattern having an illumination range on a first side of a center axis that is greater than on a second side of the center axis and a second total light pattern having an illumination range in a direction of at least one detected road user that is less than a distance to the detected road user and having an illumination range in another direction that is greater than the distance to the detected road user; wherein the control unit is configured to transmit signals to control the headlamps, during a switch from the first total light pattern to the second total light pattern, to reduce the illumination range of at least one headlamp on the first side of the center axis to at least such an extent that it is less than the distance to the detected road user and to subsequently produce the second total light pattern; wherein in the second total light pattern, a center region having a lower illumination range is formed in the direction of the detected road user, and side regions, which have a greater illumination range, are formed on both sides adjacent to the center region; and wherein in the second total light pattern, the side regions each form a vertical light-dark cutoff to the center region.
