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 6):
An own position estimation method comprising:\n detecting positions of landmarks present around a vehicle relative to the vehicle by a landmark position detector mounted in the vehicle; detecting a movement amount of the vehicle by a movement amount detector; accumulating the positions of the landmarks relative to the vehicle detected by the landmark position detector as landmark position data by coordinates based on the movement amount detected by the movement amount detector; extracting straight lines from the landmark position data accumulated at a plurality of times; selecting pieces of the landmark position data based on angles formed by intersecting ones of the extracted straight lines; and estimating a position of the vehicle by matching the selected pieces of the landmark position data and positions of landmarks in map information.
