Abstract
In traveling toward a destination, locus data for routes traveled by a vehicle is repeatedly learned and stored, and a route is identified in route searching using the stored locus data. The stored locus data may be rearranged or deleted, and undesired locus data is not used in route searching. Storage of locus data may be limited to certain areas so as not to store undesired locus data. The geographical coordinates of the stored locus data are corrected, as required, and locus data such as links are correctly shown on a map.
