Man-machine interface for motor vehicle
First Claim
Patent Images
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, 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 (MEMS) mirror, wherein the at least one MEMS mirror turns about two rotation axes to carry out a scan;
wherein the display means comprise a diffuser screen of the exit pupil expander type, 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 the intermediate image to the viewing screen,wherein the three-dimensional mirror is a curved polygonal mirror,wherein the interface is provided with a cover, the cover comprising a covering on the viewing screen, and wherein the cover closes the display means, the laser projector, and the three-dimensional mirror to be behind the viewing screen and the control means, andwherein a position of a rear face of the cover is conditioned by an angle of inclination of the three-dimensional mirror with respect to a vertical axis such that an end of the three-dimensional mirror limits a thickness of the man-machine interface.
