<p>PROBLEM TO BE SOLVED: To perform more precise vehicle control in consideration of a road kind, road with, a turning angle in a curve, etc., in addition to a road shape by correcting extracted curvature information by using predetermined road attributes as correction information. SOLUTION: A correction information extracting means consists of a data storage part 12 and a navigation process part 11 and extracts specific information as the correction information for correcting curvature information. When the correction information is extracted, the navigation process part 11 as a correcting means judges whether the correction information corresponds to an intersection or not, a ramp way or not, and a road kind for a high- and intermediate-speed travel before accumulating the angle of the intersection and does not include the angle of intersection of a link in the accumulation of intersection angles when it corresponds to them. Consequently, the curvature information corrected by the correcting means is obtained. A control means performs control for changing the control pattern of a speed variation ratio according to the accumulation of the angles of intersections as the found curvature information.</p> |
