Claim 3:
4. The lane shape recognition system according to claim 1,
wherein the curve effective range determiner sets a combination of the two curves from the plurality of curves;
sets a front and back reference position within an overlapping range in a front and back direction of the own vehicle where a range in the front and back direction where the series of marks or object used for each approximation of the two curves are disposed overlaps between the two curves;
calculates a width in the right and left direction of the own vehicle between the two curves at the front and back reference position, as a reference width; and
determines a range in the front and back direction where an absolute value of deviation between a width in the right and left direction between the two curves at a position in the front and back direction and the reference width becomes smaller than a width deviation threshold value, as the effective range.
