APPARATUS AND METHOD FOR CREATING ROAD GRADIENT DATA, STORAGE MEDIUM, AND APPARATUS FOR PREDICTING ENERGY CONSUMPTION OF VEHICLE

摘要

PROBLEM TO BE SOLVED: To create gradient data expressing gradient degrees of respective links in road map data as data suited for prediction of energy consumption.;SOLUTION: A body part 16 inputs link data from a map database 17, inputs altitude data from an altitude database 18 and inputs calculation data from a calculation data storage part 19. The body part 16 includes: a link configuration allocation part 20 for allocating link configuration points of respective links when creating fuel conversion gradient data; a gradient change point extraction part 21 for extracting such a point at that a degree of a gradient change in a straight line before and after a link configuration point is larger than a threshold as a gradient change point based on the altitude data of each link configuration point; and a calculation part 22 for calculating fuel conversion gradient data of each link.;COPYRIGHT: (C)2013,JPO&INPIT
