Abstract: The present disclosure relates to a method for performing vehicle position recognition using a geomagnetic sensor by calibrating the geomagnetic sensor on the basis of a geomagnetic sensor value stored in a database in advance before entrance to an area in which position recognition through a GPS is impossible. Thus, it is possible to accurately detect a position of a vehicle using the geomagnetic sensor even in a structure such as a tunnel.
