Abstract

A motor vehicle has a surroundings lighting device, where the surroundings lighting device includes a first projection module arranged adjacent to a pivotable vehicle door of the motor vehicle in an immobile vehicle bodywork component, where when the first projection module is switched on, the first projection module projects a light distribution onto the ground adjacent to the immobile vehicle bodywork component. A second projection module is arranged on the outside of the vehicle door, where when the second projection module is switched on, the second projection module projects a pictogram onto the ground. The surroundings lighting device is configured to, when an event which is triggered by a user in the surroundings of the motor vehicle is detected, switch on the first projection module and at the same time, or after a delay, switch on the second projection module such that the pictogram is projected onto the light distribution.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a surroundings lighting device, wherein the surroundings lighting device comprises:
a first projection module which is disposed in an immobile vehicle body part that is adjacent to a pivotable vehicle door of the motor vehicle, wherein when the first projection module is switched on, the first projection module projects a light distribution onto ground adjacent to the immobile vehicle body part; and
a second projection module which is disposed on an outer side of the pivotable vehicle door, wherein when the second projection. module is switched on, the second projection module projects a pictogram onto the ground;
wherein the surroundings lighting device is configured to, when an event that is triggered by a user in a surrounding of the motor vehicle is detected, switch on the first projection module and at a same time, or after a delay, switch on the second projection module such that the pictogram of the second projection module is projected onto the light distribution of the first projection module.

2. The motor vehicle as claimed in claim 1 , wherein the event is an operator control operation of a mobile identification encoder by the user in the surrounding of the motor vehicle and/or an undershooting of a distance between the motor vehicle and the mobile identification encoder, wherein the mobile identification encoder is carried by the user and is assigned to the motor vehicle.

3. The motor vehicle as claimed in claim 1 , wherein when the first projection module is switched on partial regions of the light distribution are successively projected onto the ground until an entire light distribution of the light distribution is projected onto the ground.

4. The motor vehicle as claimed in claim 2 , wherein when the first projection module is switched on partial regions of the light distribution are successively projected onto the ground until an entire light distribution of the light distribution is projected onto the ground.

5. The motor vehicle as claimed in claim 1 , wherein the second projection module is disposed in an external rear view mirror of the pivotable vehicle door or in a camera holder of the pivotable vehicle door.

6. The motor vehicle as claimed in claim 2 , wherein the second projection module is disposed in an external rear view mirror of the pivotable vehicle door or in a camera holder of the pivotable vehicle door.

7. The motor vehicle as claimed in claim 3 , wherein the second projection module is disposed in an external rear view mirror of the pivotable vehicle door or in a camera holder of the pivotable vehicle door.

8. The motor vehicle as claimed in claim 1 , wherein a predefined region in the light distribution is projected visually darker than sections of the light distribution which are adjacent to the predefined region and wherein the pictogram of the second projection module is projected into the predefined region.

9. The motor vehicle as claimed in claim 2 , wherein a predefined region in the light distribution is projected visually darker than sections of the light distribution which are adjacent to the predefined region and wherein the pictogram of the second projection module is projected into the predefined region.

10. The motor vehicle as claimed in claim 3 , wherein a predefined region in the light distribution is projected visually darker than sections of the light distribution which are adjacent to the predefined region and wherein the pictogram of the second projection module is projected into the predefined region.

11. The motor vehicle as claimed in claim 5 , wherein a predefined region in the light distribution is projected visually darker than sections of the light distribution which are adjacent to the predefined region and wherein the pictogram of the second projection module is projected into the predefined region.

12. The motor vehicle as claimed in claim 1 , wherein the surroundings lighting device is further configured to, after the first and the second projection modules have been switched on, immediately switch off or dim the pictogram of the second projection module when the pivotable vehicle door is opened.

13. The motor vehicle as claimed in claim 2 , wherein the surroundings lighting device is further configured to, after the first and the second projection modules have been switched on, immediately switch off or dim the pictogram of the second projection module when the pivotable vehicle door is opened.

14. The motor vehicle as claimed in claim 3 , wherein the surroundings lighting device is further configured to, after the first and the second projection modules have been switched on, immediately switch off or dim the pictogram of the second projection module when the pivotable vehicle door is opened.

15. The motor vehicle as claimed in claim 5 , wherein the surroundings lighting device is further configured to, after the first and the second projection modules have been switched on, immediately switch off or dim the pictogram of the second projection module when the pivotable vehicle door is opened.

16. The motor vehicle as claimed in claim 8 , wherein the surroundings lighting device is further configured to, after the first and the second projection modules have been switched on, immediately switch off or dim the pictogram of the second projection module when the pivotable vehicle door is opened.

17. The motor vehicle as claimed in claim 1 , wherein the surroundings lighting device further comprises a third projection module which is disposed on an inner side of the pivotable vehicle door, wherein when the pivotable vehicle door is opened after the first and the second projection modules have been switched on, the third projection module projects a further pictogram onto the ground, wherein the further pictogram moves into the light distribution when the pivotable vehicle door is opened.

18. The motor vehicle as claimed in claim 17 , wherein the further pictogram has a same shape as the pictogram of the second projection module.

19. The motor vehicle as claimed in claim 17 , wherein at a maximum opening angle of the pivotable vehicle door the further pictogram is disposed at a position of the pictogram of the second projection module when the vehicle door is closed.

20. The motor vehicle as claimed in claim 17 , wherein a brightness of the further pictogram increases slowly when the pivotable vehicle door is opened.
