Abstract:
A boundary line recognition apparatus recognizes a boundary line that demarcates a driving lane in which an own vehicle is driving and includes a candidate detecting unit, a dowel bar determining unit, and a boundary line recognizing unit. The candidate detecting unit detects line types of boundary line candidates that are candidates for the boundary line and a quantity of boundary line candidates of the same line type, based on detection data of the boundary line candidates acquired from a detecting unit that detects the boundary line candidates. The dowel bar determining unit determines whether or not the boundary line candidates are formed by dowel bars embedded in a road, based on the line type and quantity detected by the candidate detecting unit. The boundary line recognizing unit eliminates the boundary line candidates that are determined to be formed by the dowel bars and recognizes the boundary line.

Claim (Index 16):
The boundary line recognition apparatus according to  claim 1 , further comprising:\n a lane storage unit ( 32 , S 454 , S 462 , S 472 ) that stores, in a storage apparatus, a lane width of the driving lane and positions of the boundary lines based on the boundary lines recognized by the boundary line recognizing unit, wherein: when all of the boundary line candidates in at least one of left and right areas ahead of the own vehicle are formed by the dowel bars based on a current recognition result, and when at least one of the boundary line candidates is present within a predetermined range near a stored position of the boundary line that is stored in the storage apparatus by the lane storage unit, the boundary line recognizing unit (S 458 ) offsets, to the stored position, one of the boundary line candidates nearest the stored position among the at least one of the boundary line candidates, and recognizes the one of the boundary line candidates as the boundary line; and when all of the boundary line candidates in one of left and right areas are formed by the dowel bars based on a current recognition result, and when none of the boundary line candidates is present within a predetermined range near the stored position, the boundary line recognizing unit (S 466  to S 470 ) offsets, to an offset position, one of the boundary line candidates nearest the offset position among the all of the boundary line candidates, and recognizes the one of the boundary line candidates as the boundary line, the offset position being separated from a position of the boundary line recognized in the other of the left and right areas by a distance amounting to the lane width or by a distance amounting to a predetermined lane width.
