Abstract

A method for operating a vehicle comprising at least one light source designed to emit light for illuminating the surroundings of the vehicle is described. The method comprises the following steps: determining whether a road user approaches the vehicle to within a predetermined distance; determining the distance between the road user and the vehicle; and illuminating the surroundings of the vehicle by use of the at least one light source at the side of the vehicle from which the road user approaches the vehicle should the distance between the road user and the vehicle drop below a first threshold distance.

First claim

What is claimed is:

1. A method for illuminating a side of a vehicle, comprising:
determining a road user approaching the vehicle, wherein the road user comprises an oncoming vehicle;
determining a distance between the road user and the vehicle; and
illuminating with at least one light source, that is configured to be rotatable about a vertical axis through a set angle, ground in front of the oncoming vehicle to provide lighting in front of the oncoming vehicle for the oncoming vehicle when the distance between the oncoming vehicle and vehicle drops below a first threshold distance.

2. The method as claimed in claim 1 , wherein there is a determination as to whether at least one of the application of the method is allowed at the location used by the vehicle and whether the ambient light has a luminosity below a threshold value prior to the implementation of the step of illuminating.

3. The method as claimed in claim 1 , wherein the light source is configured as a lamp.

4. The method as claimed in claim 1 , wherein the vehicle comprises at least one of a roof, longitudinal axis, and the light source is arranged on the roof of the vehicle, and at least one lateral side face in relation to the longitudinal axis and the light source is arranged at the at least one lateral side face.

5. The method as claimed in claim 4 , wherein the light source is rotated about the vertical axis through a set angle when illuminating the side of the vehicle.

6. The method as claimed in claim 1 , wherein determining a road user approaching the vehicle to within a set distance is carried out by use of at least one of a detector, vehicle-to-vehicle communication, and communication between the vehicle and a mobile appliance.

7. The method as claimed in claim 1 , wherein the road user further comprises a pedestrian, a bicycle or a motor vehicle.

8. The method as claimed in claim 1 , wherein the vehicle comprises at least one of a headlamp and a lamp with a full beam, and wherein a light intensity of the at least one headlamp and lamp with a full beam is at least one of reduced and deactivated when the distance between the road user and the vehicle drops below a second threshold distance.

9. The method as claimed in claim 8 , wherein illumination of surroundings of the vehicle is reduced or terminated when the distance between the road user and the vehicle drops below a third threshold distance or be situated next to the vehicle.

10. The method as claimed in claim 1 , wherein a direction of the illumination is adapted to at least one of a current position of the road user and a movement direction of the road user.

11. The method as claimed in claim 10 , wherein the direction of the illumination is adapted by rotating the light source.

12. The method as claimed in claim 1 , wherein a signal is transmitted to the road user when the illumination illuminates an area in front of the road user.

13. The method as claimed in claim 12 , wherein the signal comprises a communication that at least one of a full beam can be deactivated, the light intensity of at least one headlamp can be reduced, and at least one headlamp can be deactivated.

14. A lighting system for a vehicle, comprising:
a device for determining a road user, wherein the road user comprises an oncoming vehicle, approaching the vehicle and determining the distance between the road user and the vehicle; and
at least one light source that is configured to be rotatable about a vertical axis through a set angle for illuminating ground in front of the oncoming vehicle to provide lighting in front of the oncoming vehicle for the oncoming vehicle when the oncoming vehicle approaches the vehicle within a distance below a first threshold distance.

15. The lighting system as claimed in claim 14 , wherein the vehicle comprises at least one of a headlamp and at least one lamp with a full beam, wherein at least one of the light intensity of the at least one headlamp is reduced, and at least one of the headlamp and the at least one lamp with a full beam is deactivated when the distance between the road user and the vehicle drop below a second threshold distance.

16. The lighting system as claimed in claim 15 , wherein the illumination of the side of the vehicle is reduced or terminated should the distance between the road user and the vehicle drop below a third threshold distance from the vehicle or be situated next to the vehicle.

17. The lighting system as claimed in claim 14 , wherein a direction of the illumination is adapted to at least one of a current position of the road user and to a movement direction of the road user.

18. The lighting system as claimed in claim 17 , wherein the direction of the illumination is adapted by rotating the light source.

19. The lighting system as claimed in claim 14 , wherein there is a determination as to whether at least one of the illumination of the light source is allowed at a location used by the vehicle and whether the ambient light has a luminosity below a threshold value.

20. A vehicle comprising:
a device for determining a road user approaching the vehicle and determining a distance between the road user and the vehicle, wherein the road user comprises an oncoming vehicle; and
at least one light source that is configured to be rotatable about a vertical axis through a set angle for illuminating ground in front of the oncoming vehicle to supplement lighting for the oncoming vehicle when the distance between the oncoming vehicle and the vehicle is below a first threshold distance.
