To provide a technique for enhancing a possibility that an information amount can be reduced without lowering the accuracy of a slope.SOLUTION: A road information acquisition system includes: a current position acquisition part for acquiring the current position of a vehicle; a slope acquisition part for acquiring a slope of a slope acquisition section set on a road ahead of the current position; and a road information acquisition part for acquiring road information showing of the slope about each of the start position and the end position of the slope acquisition section, a positive/negative position at which the positive/negative of the slope is converted, and a setting position at which a change in the slope is set more closely than in a section where the change of the slope is gentle in a section where the change of the slope is rapid.SELECTED DRAWING: Figure 1
【課題】勾配の精度を落とさずに情報量を削減できる可能性を高める技術の提供。【解決手段】車両の現在位置を取得する現在位置取得部と、前記現在位置の前方の道路上に設定された勾配取得区間の勾配を取得する勾配取得部と、前記勾配取得区間の開始位置および終了位置と、前記勾配の正負が転換する正負転換位置と、前記勾配の変化が急激である区間において前記勾配の変化が緩やかな区間よりも密に設定された設定位置と、のそれぞれについての前記勾配を示す道路情報を取得する道路情報取得部と、を備える道路情報取得システムを構成する。【選択図】図1
