ABSTRACT:
An on-vehicle navigation system having a route searching function for automatically selecting a guiding route to a destination in consideration of run experiences of the user. Run experience data indicative of the run experience is formed every road unit which the vehicle has run and is stored, a plurality of traveling routes which a vehicle can run between a start point and the destination are searched for and weights of the road units in the traveling route and the corresponding run experience data is obtained from memory for each of the plurality of traveling routes in the route searching operation, the weight of each road unit in the traveling route is corrected by the corresponding run experience data for each of the plurality of traveling routes, a sum value of the corrected weights corresponding to the road units in the traveling route is calculated for each of the plurality of traveling routes, and a traveling route of which sum value is the minimum is selected from the plurality of traveling routes. The route including the roads which the user has run previously is preferentially selected as a guiding route, so that a route search which makes the most of the run experience of the user is performed.
