Abstract

An illumination device of a motor vehicle includes one or more multi-aperture projection displays, where a respective multi-aperture projection display contain a luminous means for illuminating a plurality of object structures and an array of projection lenses. Each projection lens is assigned to an object structure which is projected by the respective projection lens into at least one projection plane extending perpendicularly or obliquely with respect to the ground in an area surrounding the motor vehicle. The one or more multi-aperture projection displays are configured such that an overall image containing symbols perceivable by a driver of the motor vehicle is produced in the at least one projection plane by the projected object structures.

First claim

What is claimed is:

1. A motor vehicle comprising:
an illumination device, which includes one or more multi-aperture projection displays, each multi-aperture projection display containing:
a luminous means for illuminating a plurality of object structures, and
an array of projection lenses, each projection lens assigned to a respective set of the plurality of object structures, each set including at least a first object structure and a second object structure,

wherein via simultaneous illumination of the plurality of object structures by the luminous means:
the first object structures of each set are projected by the respective projection lenses into a first projection plane extending perpendicularly or obliquely with respect to the ground in an area surrounding the motor vehicle, such that a first overall image containing first symbols perceivable by a driver of the motor vehicle are generated in the first projection plane, and
the second object structures of each set are projected by the respective projection lenses into a second projection plane, different from the first projection plane, extending perpendicularly or obliquely with respect to the ground area in the area surrounding the vehicle, such that a second overall image, different from the first overall image, containing second symbols perceivable by the driver are generated in the second projection plane,
wherein the first projection plane and the second projection plane are located at different respective distances from the motor vehicle.

2. The motor vehicle as claimed in claim 1 , wherein at least some of said symbols respectively comprise at least one character, pictogram and number.

3. The motor vehicle as claimed in claim 1 , wherein at least some of said symbols respectively indicate a distance between a corresponding projection plane and the motor vehicle.

4. The motor vehicle as claimed in claim 1 , wherein at least some of the symbols respectively comprise a warning for the driver.

5. The motor vehicle as claimed in claim 4 , wherein the warning for the driver comprises one of the symbols in a respective projection plane at a shortest distance from the motor vehicle, or the symbols in projection planes whose distance from the motor vehicle undershoots a predetermined threshold.

6. The motor vehicle as claimed in claim 1 , wherein for at least one of the one or more multi-aperture projection displays, at least one of the respective projection planes is substantially perpendicular to a front of the motor vehicle.

7. The motor vehicle as claimed in claim 1 , wherein for at least one of the one or more multi-aperture projection displays, at least one of the respective projection planes is substantially perpendicular to a rear of the motor vehicle.

8. The motor vehicle as claimed in claim 1 , wherein for at one of the one or more multi-aperture projection displays, at least one of the respective projection planes runs parallel to a longitudinal axis of the motor vehicle and is arranged in a manner offset with respect to a longitudinal side of the motor vehicle.

9. The motor vehicle as claimed in claim 8 , wherein the symbols comprise a line running parallel to the longitudinal axis of the motor vehicle.

10. The motor vehicle as claimed in claim 1 , wherein at least one of the one or more multi-aperture projection displays is provided in at least one a headlight and a taillight of the motor vehicle.

11. The motor vehicle as claimed in claim 10 , wherein the multi-aperture projection displays are respectively provided in at least one of left and right headlights and left and right taillights.
