Abstract
PURPOSE:To facilitate the recognition of a running position of a body, by always calibrating output signals of a rate sensor and a vehicle speed sensor to detect a gentle curve of a running course with the correction of the current position of a moving body. CONSTITUTION:In a straight road S on a map, an intersection (b) is determined between a line extending vertically to a speed vector V1 and the straight road S regarding the current position (a) of a vehicle calculated from a rare sensor 12 and a vehicle speed sensor 14. The position of the vehicle and azimuth errors are calculated with a signal processor 18 from a relative position between the current position (a) and the intersection (b). At the same time, the rate sensor 12 and the vehicle speed sensor 14 are calibrated with a signal processor 18 from the tendency of causing errors of the current position an the azimuth errors. A current position data calibrated is displayed continuously on a display 20 in superimposition with the map.
