Abstract
A radar (peripheral object observation device) repeatedly observes a relative position of an object relative to the moving object, which is located in the vicinity of a moving object. A stationary object identification unit (stationary object determination unit) determines whether or not the object the relative positions of which have been observed by the radar is still. A road approximate curve temporary computation unit (object correlation unit) determines a plurality of the relative positions of an identical object observed by the radar from among the relative positions observed by the radar. A road approximate curve main computation unit (approximate curve computation unit) computes an approximate curve that approximates the configuration of a road on which the moving object is located, based on a result of the determination by the stationary object identification unit and a result of the determination by the road approximate curve computation unit.
