Abstract

PURPOSE:To improve the accuracy of navigation by correcting the current position of a vehicle every time the vehicle passes by a specific structure. CONSTITUTION:A current position recognizing means 6 recognizes the current position of the vehicle on a map according to the output of a map information storage means 4. A specific structure deciding means 10 decides the presence of the specific structure according to the output of an earth magnetism sensor 8 and a real position structure specifying means 12 specifies a real position structure according to the output of a specific structure deciding means 12. A current position correcting means 14 corrects the current position on the map recognized by the current position recognizing means into the position of the real position structure according to the output of the real position structure specifying means 12.
