ABSTRACT:
A car navigation apparatus includes: a current position detection device that detects a current position of a vehicle; and a control device that detects a plurality of roads as candidates used for map matching based upon road map information containing road data used for navigation of the vehicle and the current position detected by the current position detection device, and execute map matching with a most appropriate road among the plurality of roads, and the control device does not execute map matching when a road among the plurality of roads as the candidates used for the map matching is judged to form a circular crossroad.
