Abstract

A motor vehicle includes a plurality of lights serving to illuminate the area surrounding the vehicle to the side or rear, wherein one or more sensors are provided to detect the position of a person relative to the vehicle. The lights, of which several are installed in the region of a vehicle side or the vehicle rear and illuminate the different surrounding area regions, can be activated separately depending on the detected position.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a sensor configured to detect a position of a person relative to the motor vehicle; and
at least three lights mounted in an area of a side or rear of the motor vehicle and configured to separately and sequentially illuminate at least three different regions which surround the vehicle to the side and the rear in dependence on a position detected by the sensor and which adjoin one another or partly overlap one another, with a first one of the three regions being distant to the motor vehicle and illuminated by a first one of the lights, with a second one of the three regions that is adjacent to the first one of the regions being closer to the motor vehicle and illuminated by a second one of the lights, and with a third one of the three regions that is adjacent to the second one of the regions adjoining the motor vehicle and illuminated by a third one of the lights.

2. The motor vehicle of claim 1 , wherein the sensor continuously detects the position of the person, with an activation of the lights being changeable in dependence on the continuously detected position.

3. The motor vehicle of claim 1 , wherein the lights, once the sensor has detected the position of the person, are activated according to a defined time sequence.

4. The motor vehicle of claim 1 , wherein the lights are installed in at least one vehicle structure selected from the group consisting of side mirror, door handle, and hatchback.

5. The motor vehicle of claim 1 , wherein the sensor is installed in at least one vehicle structure selected from the group consisting of side mirror, door handle, and hatchback.

6. The motor vehicle of claim 1 , wherein the lights and the sensor are installed in at least one vehicle structure selected from the group consisting of side mirror, door handle, and hatchback.

7. The motor vehicle of claim 1 , wherein each of the lights is a light-emitting diode (LED).

8. The motor vehicle of claim 1 , further comprising a control device receiving information from the sensor about a detected position of the person and individually activating the lights in dependence on the detected position to thereby generate a moving light.

9. The motor vehicle of claim 1 , wherein the lights are installed in a side mirror of the motor vehicle, while the sensor is installed in a door handle of the motor vehicle.

10. A method, comprising:
installing at least three lights in an area of a side or rear of a motor vehicle;
monitoring an area surrounding the vehicle to the side and the rear for detecting the presence of a person relative to the motor vehicle; and
sequentially illuminating at least three different regions, which surround the motor vehicle to the side and the rear in dependence on a detected position and which adjoin one another or partly overlap one another, by separately activating the at least three lights so as to produce a moving light, with a first one of the three regions being distant to the motor vehicle and illuminated by a first one of the lights, with a second one of the three regions that is adjacent to the first one of the regions being closer to the motor vehicle and illuminated by a second one of the lights, and with a third one of the three regions that is adjacent to the second one of the regions adjoining the motor vehicle and illuminated by a third one of the lights.

11. The method of claim 10 , wherein the lights have different alignments so as to emit light in different directions.

12. The method of claim 10 , wherein the sensor continuously detects the position of the person, with an activation of the lights being changeable in dependence on the continuously detected position.

13. The method of claim 10 , wherein the lights are activated according to a defined time sequence.

14. The method of claim 13 , wherein the lights are deactivated after 1-3 seconds.

15. The method of claim 10 , wherein the lights are deactivated when a subsequent one of the lights is activated.

16. The method of claim 10 , wherein the lights are installed in at least one vehicle structure selected from the group consisting of side mirror, door handle, and hatchback.

17. The method of claim 10 , wherein the sensor is installed in at least one vehicle structure selected from the group consisting of side mirror, door handle, and hatchback.

18. The method of claim 10 , wherein the lights are installed in a side mirror of the motor vehicle, while the sensor is installed in a door handle of the motor vehicle.
