Abstract

A calculation device for use in a vehicle, having a housing and having a first planar display, disposed in the housing, for direct readout of information in the planar display, and having a second projection unit, disposed in the housing, for generating a virtual image, in particular on a windshield of the vehicle.

Claims

1-8. -8. (canceled)

9. A device for use in a vehicle, comprising:

a housing;

a planar display, situated in the housing, for direct readout of information in the planar display; and

a projection unit, situated in the housing, for generating a virtual image by projection.

10. The device according to claim 9, wherein the projection unit generates a virtual image by projection onto a windshield of the vehicle.

11. The device according to claim 9, wherein the projection unit includes a plurality of light-emitting diodes that can at least in part be triggered separately.

12. The device according to claim 9, wherein the housing has a narrow side, and the projection unit is situated on the narrow side of the housing.

13. The device according to claim 9, wherein the housing can be folded out, and the projection unit is situated on an inner side of the housing.

14. The device according to claim 9, wherein a plurality of different symbols can be projected with the projection unit, a separate light source assemblage being provided for each symbol.

15. The device according to claim 9, further comprising a sensing unit for ascertaining whether the device is inserted into a holder, and for automatically deactivating the projection unit after a removal of the device from the holder.

16. The device according to claim 9, further comprising a route determination unit for determining a route of travel to a destination and for outputting driving advisories via at least one of the planar display and the projection unit.

17. The device according to claim 9, wherein the device is used to generate a virtual image in a windshield of a motor vehicle.
