摘要:
Disclosed is an apparatus for displaying a travel position, which, in carrying out steps of calculating X- and Y-coordinates of a current position of the moving body; renewably presents said current position on a road map indicated on a display screen; matches between a travel trace pattern formed by subsequent current positions and each road pattern on the road map; and puts the travel trace on the mated road pattern for correction of the current position of the moving body deviated from the road on the map, to determine what class of the road the moving body is running on, e.g. mountain road, superhighway or other ordinary road, and also changes the pattern matching condition to be adapted for the class of the road, as determined by a measured number of curves per unit of distance.
