Abstract
A motor vehicle has projection unit that includes comprises a projection surface and a projector and is designed in such a way that in a normal situation, a light signal can be projected onto an illumination area of the projection surface by the projector. The illumination area of the projection surface is at least partially represented by a light-reflecting roof area of the motor vehicle. The projection surface has a transparent glass area. The projection unit is designed in such a way that in an emergency situation, the light signal can be projected towards the outside through the glass area by the projector and the motor vehicle can be recognized from the outside.
Claims9
A motor vehicle comprising:
- an interior;
- a projection unit arranged in the interior and having a projection surface and at least one projector,
- wherein the projection unit is configured such that in a normal situation, a light signal is projected onto a light-reflecting illumination area of the projection surface by the at least one projector,
- wherein the illumination area of the projection surface at least includes a light-reflecting roof surface of the motor vehicle facing towards the interior,
- wherein the projection surface has an outwardly transparent glass area,
- wherein the projection unit is configured such that in an emergency situation, the light signal is projected towards an outside of the vehicle through the outwardly transparent glass area by the at least one projector, and the motor vehicle is recognizable from the outside,
- wherein, in the emergency situation, the light signal is formed by projecting at least one static or temporally changing pattern or at least one static or temporally changing graphic onto the outwardly transparent glass area of the projection surface.
A method for controlling a projection unit of a motor vehicle arranged in an interior of the motor vehicle, the method comprising:
- projecting, by the projection unit in a normal situation, a light signal onto a light-reflecting illumination area of a projection surface of the projection unit by at least one projector of the projection unit, wherein the illumination area of the projection surface at least includes a light-reflecting roof surface of the motor vehicle facing towards the interior, wherein the projection surface has an outwardly transparent glass area;
- and
- projecting, by the projection unit in an emergency situation, the light signal towards an outside of the vehicle through the outwardly transparent glass area by the at least one projector, and the motor vehicle is recognizable from the outside,
- wherein, in the emergency situation, the light signal is formed by projecting at least one static or temporally changing pattern or at least one static or temporally changing graphic onto the outwardly transparent glass area of the projection surface.
A projection unit for the motor vehicle, the projection unit comprising:
- a projection surface;
- and
- at least one projector,
- wherein the projection unit is configured such that in a normal situation, a light signal is projected onto a light-reflecting illumination area of the projection surface by the at least one projector,
- wherein the illumination area of the projection surface at least includes a light-reflecting roof surface of the motor vehicle facing towards the interior,
- wherein the projection surface has an outwardly transparent glass area,
- wherein the projection unit is configured such that in an emergency situation, the light signal is projected towards an outside of the vehicle through the outwardly transparent glass area by the at least one projector, and the motor vehicle is recognizable from the outside,
- wherein, in the emergency situation, the light signal is formed by projecting at least one static or temporally changing pattern or at least one static or temporally changing graphic onto the outwardly transparent glass area of the projection surface.
