Claim:
A driving support system comprising: a curve information acquisition unit configured to acquire information on a shape of a curvature changing portion in a road, said road having the curvature changing portion of which a radius of curvature changes according to a predetermined function; a driving support unit configured to perform driving support for a driver at the time when a vehicle moves in said curvature changing portion; and a driving support control unit configured to decide timing at which said driving support unit performs driving support, based on the information on the shape of said curvature changing portion acquired by said curve information acquisition unit; characterized in that said driving support control unit decides the timing at which said driving support unit performs driving support, based on a length of said curvature changing portion; and in cases where the length of said curvature changing portion is equal to or more than a threshold value, said driving support control unit makes a decision that said driving support unit performs driving support.
