Zusammenfassung:	PURPOSE: To provide an on-vehicle navigation apparatus in which map matching of sufficiently high accuracy correction can be conducted even if the accuracies of various detector such as a vehicle speed detector, a gyro sensor, etc., and low. CONSTITUTION: A projection matching judging unit 12 conducts a projection matching based on present position data from a present position orienting unit 5 and estimated present position data supplied from an estimated present position deciding unit 9 according to a signal from a 30m judging unit 7. A pattern matching judging unit 11 executes a pattern matching based on a traveling locus supplied from a traveling locus vector generator 8 and an estimated traveling locus supplied from an estimated locus vector generator 10 according to a signal from a 150m judging unit 6. A display controller 13 generates position data supplied from the unit 12 or 11 and image data superposed with road map of the periphery, and outputs it to a display 14.
