Abstract

Man-machine interface for motor vehicle comprising a display screen (6) and a control means on which the user of the vehicle can act in order to alter a parameter of the vehicle, characterized in that it also comprises displaying means (16) and a laser projector (14), the displaying means being designed to receive an image from the laser projector and to display it on the display screen.

Claims

1. A man-machine interface for a motor vehicle, said interface comprising:

a viewing screen and a control means, on which a user of the vehicle can act in order to modify a parameter of the vehicle,

display means and a laser projector, the display means being arranged in order to receive and display an image coming from the laser projector on the viewing screen.

2. The man-machine interface as claimed in claim 1, wherein the display means comprise:

a diffuser screen on which an intermediate image is formed from the projection of the image onto said diffuser screen by the laser projector; and

a three-dimensional mirror for deforming the intermediate image in order to adapt it to the viewing screen.

3. The man-machine interface as claimed in claim 2, wherein the three-dimensional mirror is a mirror having a freeform reflection surface.

4. The man-machine interface as claimed in claim 2, wherein the laser projector comprises:

three laser sources, each of the three sources being capable of emitting a monochromatic light beam of one of red, green or blue; and

a scanning device comprising at least one microelectromechanical system mirror, referred to as a MEMS mirror.

5. The man-machine interface as claimed in claim 1, wherein the control means comprises a touch screen arranged on the viewing screen.

6. The man-machine interface as claimed in claim 1, wherein the control means comprises a pushbutton or rotary button integral with the interface.

7. The man-machine interface as claimed in claim 6, wherein the pushbutton or rotary button is supported by the viewing screen.

8. The man-machine interface as claimed in claim 1, wherein the viewing screen has a curved surface.

9. The man-machine interface as claimed in claim 1, wherein the viewing screen has a frosted appearance.

10. The man-machine interface as claimed in claim 1, comprising means for driving the laser projector.

11. The man-machine interface as claimed in claim 1, said interface being provided with a cover.

12. The man-machine interface as claimed in claim 1, wherein the thickness of the man-machine interface is less than 100 mm.
