Abstract:
1. A navigation device comprising: a vehicle position detection unit that detects a vehicle position; a matching candidate selection unit that selects candidates for a road on which a vehicle position mark is to be shown from map data based on the detected vehicle position; a matching process unit that determines the road on which the vehicle position mark is to be shown based on a coefficient calculated by relative comparison of a road candidate and the vehicle position from the selected road candidates; a road name determination unit that determines whether a road name of the road candidate coincides with the road name of the road previously determined by said matching process unit; a weighting unit that weights the coefficient of the road candidate that said road name determination unit determines has the road name which coincides with the road name of the road previously determined by said matching process unit; and a display control unit that displays the vehicle position mark on the road determined by said matching process unit.
