Embodiment Construction

[0071] Embodiments of the elevation reliability judging system of the present invention will be described with reference to the drawings. The elevation reliability judgment system 1 of the present embodiment is used to judge the estimated elevation reliability C of the estimated elevation h calculated based on the road information R and the elevation information H. In this embodiment, an example in which the elevation reliability judgment system 1 is applied to the data maintenance system 2 and the driving support system 3 will be described, wherein the data maintenance system 2 corrects the estimated elevation h and stores it in the map database 6 , the travel support system 3 executes various support processes AP related to the travel of the vehicle. In addition, in this embodiment, each system constitutes a part of the navigation system. In addition, each system has a plurality of functional units, but each functional unit may be shared by a plurality of systems.

Abstract

This invention relates to an altitude reliability determining system comprising: a map information acquiring unit (11) that acquires map information including road information and background information, an altitude information acquiring unit (13) that acquires altitude information indicating an altitude of each unit region, the unit region being set by dividing a map indicated in the map information into a plurality of unit regions having a predetermined size, an altitude calculating unit (14) that calculates a predicted altitude of each of a plurality of reference points based on the road information and the altitude information, the plurality of reference points being set along a road.

Description

technical field [0001] The present invention relates to an elevation reliability judgment system for judging the reliability of an estimated elevation calculated based on road information and elevation information, and to a data maintenance system and a driving support system using the elevation reliability judgment system. Also, the present invention relates to an elevation reliability judgment program and method for judging the reliability of an estimated elevation calculated based on road information and elevation information. Background technique [0002] There are known driving assistance systems that determine the control characteristics of a vehicle based on the elevations of road surfaces at multiple points on the road, or provide information about the future of the vehicle to the driver. For example, in the system disclosed in Japanese Unexamined Patent Publication No. 2004-037141 (Patent Document 1), the elevation information (mesh elevation data: mesh altitubedata...
