An information processing station having map data is provided at an external position outside of a vehicle. In-vehicle equipment determines a vehicular travel path of the vehicle, and transmits the determined vehicular travel path to the information processing station. The information processing station executes map matching processing of matching the vehicular travel path with a road on the map data, thereby correcting the present position of the vehicle. Accordingly, the present position of the vehicle can be determined with high precision without providing expensive map data to the vehicle.
