Vehicle navigation system
First Claim
1. A navigation apparatus comprising:
- map information storage means for storing therein map information;
target data storage means for storing guidance information as to a target object which users can optionally select;
present position detection means for detecting a present position of a vehicle;
route search means responsive to map information as stored in said map information storage means, for searching for a route to a destination;
route information storage means for storing a route searched by said route search means;
target object retrieve means for retrieving a target object within a predetermined range from and along said route stored in said target data storage means on the basis of a route stored in said route information storage means; and
output means for outputting a target object retrieved by said target object retrieve means on the map around the present position.

Abstract
A navigator apparatus includes a map memory for storage of road map information, and a target data memory storing therein guidance information as to a destination or target object under search. A present position detector is provided for detecting a present position of a mobile vehicle. A route finder responsive to receipt of part of the map information for attempting to find out a route leading to a nearby position of the target from one of a start point of the vehicle and the present position thereof. A target searcher functions to search for a position of the target being presently stored in the target data memory in correspondence with the map information as stored in the map memory. The map information and resultant information as to the target found are both visually indicated on the screen of an associated display device while permitting voice guidance.

20. A navigation apparatus comprising:
-
map information storage means for storing therein map information; target data storage means for storing guidance information to multiple target objects which users can optionally select, each target object of the multiple target objects constituting a point of destination; present position detection means for detecting a present position of a vehicle; route search means, responsive to map information as stored in said map information storage means, for searching for a route to an ultimate destination; route information storage means for storing the route to the ultimate destination searched by said route search means; target object retrieve means for retrieving at least one target object of the multiple target objects stored in said target data storage means within a predetermined range from and along the route to the ultimate destination, the target object retrieve means giving priority to target objects that are closer to the route to the ultimate destination stored in the route information storage means than other target objects; and output means for outputting the at least one target object retrieved by said target object retrieve means on the map around the present position, so as to provide guidance information to the at least one target object which is most conveniently located relative to the route to the ultimate destination.
