Abstract:
An own-position estimation device: detects positions of landmarks present around a vehicle; accumulates the detected positions of the landmarks as landmark position data based on a movement amount of the vehicle; extracts straight lines from the accumulated landmark position data; selects pieces of the landmark position data used for own-position estimation based on angles formed by intersecting ones of the extracted straight lines; and estimates a position of the vehicle by matching the selected pieces of the landmark position data and positions of landmarks in map information.

Claim (Index 3):
The own-position estimation device according to  claim 1 , wherein the landmark position selector sets priorities of pieces of straight line information such that the greater the angles formed by the intersecting ones of the straight lines equal to or less than 90\u00b0 are, the higher the priority is set to combinations of the intersecting ones of the straight lines, and selects the pieces of the landmark position data in a descending order of the priorities set for the pieces of straight line information.
