VEHICLE LOCATION SYSTEM ON A MAP DISPLAY |
摘要 |
There is disclosed an apparatus for displaying the constantly changing current location of a vehicle on a two-dimensional coordinate system while detecting the distance travelled by the vehicle and its direction of travel. The current location is displayed on a map on a display screen on the basis of computed data. The apparatus extracts a linear travel segment from the current location of the vehicle by storing data of the current location, extracts a linear road segment from adjoining roads on the map, which corresponds to the linear travel segment extracted from the current location, matches the extracted travel segment and linear road segment depending on their positional relationship, and puts the current location onto the road for which matching has occurred.
