ABSTRACT:
The invention provides various methods for detecting the bearing of a moving vehicle and of processing data in a vehicular navigation system. Provided there is carried out a process of recognizing the present position of the vehicle while the vehicle is moving at a predetermined speed, bearing data obtained from a prestored map is utilized to determine the present position of the vehicle. At that time, the data output from a terrestrial magnetism sensor, which would otherwise be used, is discarded.
