ABSTRACT:
A momentarily changing position of a travelling vehicle is correctly identified by a vehicular nagivation system on which a magnetism sensor, angular velocity sensor, travel distance sensor and global positioning system are mounted. The current position of the vehicle is identified by, for example, storing data of a road on a map in the form of numerical values, measuring a predetermined distance which the vehicle has travelled and computing the current position on the road based upon the predetermined distance thus measured.
