Route guidance display device

Claim 2

An on-board route guidance display device for a motor vehicle comprising: a plurality of display segments arranged in pattern corresponding to a predetermined road route pattern, said display segments intersecting at a predetermined position, and display segments being arranged to provide a viewer with a perception of depth, at least two of said display segments in a position corresponding to a straight-ahead route being stacked one on the other for providing a depth-enhancing effect; and a plurality of route guidance indicators arranged upon at least predetermined ones of said display segments, wherein said display segments can be activated in a desired combination to indicate a pattern of road routes being encountered by said vehicle.

Claim 3

The route guidance display device of claim 1, wherein said road route patterns include both plane intersecting patterns and overpass intersecting patterns.

Claim 4

The route guidance display device of claim 1, wherein said at least two of said display segments are of different display colors.

Claim 5

In a route guidance display system for a motor vehicle, said route guidance display system having an external memory programmed with map data including intersections and main routes, a display device for displaying said map-data, an input device for inputting a starting point and a destination onto a map displayed on said display device, sensor means for detecting a distance and direction of travel of said vehicle, and data processing means for processing display data based on map data from said external memory, data inputted from said input device, and information outputted from said sensors to provide a driver information regarding the current position of said vehicle, congestion on said main routes, a best route to said destination, and a configuration and name of a next intersection; and a route guidance display device comprising: an intersection configuration display section for displaying said configurations of intersections, and an intersection name display section for displaying said names of intersections, both said display sections being provided on a common display panel having a predetermined number of display colors, said intersections configuration display section being separate from said device for displaying said map data.

Claim 6
