ABSTRACT:
Vehicle control data is stored in a database of a vehicle control information storage apparatus of the present invention by a unit of road segment. When the same vehicle travels the same road segment for plural times, vehicle speed is averaged for storage as the vehicle control information in the database. Further, learning data has a value that is smaller than a threshold for the segment next to a current segment with a fulfillment of other conditions, the data is combined before storage in the database, thereby achieving a smaller storage volume in the database for the same amount of control information.
