正手段とから構成された車載用航法装置。 A position detection sensor that detects the current position of a running vehicle, a storage medium that stores road map information, and a current position of the vehicle is calculated based only on data from the position detection sensor, and data from the position detection sensor. and a calculation means that calculates the current position of the vehicle by taking into account the data from the storage medium, and the current position of the vehicle, which is normally calculated based on the data from the position detection sensor and the data from the storage medium, on the road of the above map information. a matching means for matching the results of the matching with the matching means; a display means for displaying the matching result by the matching means; and a display means for displaying the matching result by the matching means, and a display means for displaying the current position of the vehicle calculated from the data from the position detection sensor and the data from the storage medium, which corresponds to a predetermined position on the road in the map information. When passing, the current position of the vehicle is calculated using data from the position detection sensor and data from the storage medium, and within a certain range centered on the midpoint of the current position of the vehicle calculated only from data from the position detection sensor. An in-vehicle navigation device comprising a correction means for searching for a road located in the area and matching it as a road to be traveled on.
