Head-up displays on motor vehicles often have double images and interfering reflections on the windshield. To avoid these, arrangements of linear polarization filters or shutter foils are suggested, which have particularly high light transmission. Arrangements of filter plates on a combiner inside of the windshield are also advantageous.

Head-up display device for motor vehicles

An opto-electronic indicating matrix comprises a plurality of row and column segments controllable in a multiplex operation, and means for electrically connecting the row and column segments and including a plurality of conductors arranged in regions between the row segments and inclined to a longitudinal axis of the row axis so as to extend parallel to one another in one plane. A preferable application of the matrix is in an indicator for travel guiding information in a power vehicle.

Opto-electronic indicating matrix, and indicating device provided

A system of navigation for vehicles is proposed, which is provided with a device (14) for representing a road map as well as with a composite navigation apparatus (10, 11, 12) for the continuous instantaneous determination of the location of the vehicle and with a location display (16) on the representation of the road map. Deviations of the location from the course of the roads on the road map are detected and corrected. In order to be able to input a desired trip route (21) into the navigation system without an additional representation of the road map, prior to the beginning of the trip the desired trip route is traced by hand, using an input device (17, 18) connected to a trip route memory, with a wand (19) on the existing representation (14) of the road map, and thereby stored in the trip route memory (13). (Fig. 1).

System of navigation for vehicles

A process for determining navigation data from a map wherein a line code lattice is superposed on the map and scanned by a sensor. The crossing line codes in the lattice differ one from the other.
