First Claim
1. A navigation system for vehicles, comprising:
- present position detecting means for detecting the present position of a vehicle;
input means for inputting for a destination;
information storage means for storing map data;
locus data accumulating means for accumulating locus data for locus traveled by a vehicle based on coordinate information for the present position detected by said present position detecting means;
route calculating means for calculating a route to the destination based on the map data stored in said information storage means and the locus data accumulated by said locus data accumulating means;
route information storage means for storing the route calculated by said route calculating means; and
guiding means for providing route guidance based on the route stored in said route information storage means.

Abstract
In a navigation system, user preferred road data is determined and stored during travel to supplement fixed road data such as map data, intersection data, node data, and destination data stored in CD-ROM for subsequent use in providing route guidance in accordance with user road preferences. The user preferred road data is the data of actual trips, and the preference of the user is reflected in the user preferred road data. To determine user preferences, either the user preferred road data is compared to the fixed road data or a searched route calculated from the user preferred road data and CD-ROM data is compared with the searched route calculated from CD-ROM data. By using the determined user preferences in route searching, it is possible to provide more elaborate route searching and route guidance in accordance with the preference of the user.
