DETECTION DEVICE, DETECTION METHOD, AND PROGRAM FOR THE SAME

PROBLEM TO BE SOLVED: To detect a start point and an end point of a sloping road in a road without actual traveling, to detect a slope section.SOLUTION: A detection device 10 comprises: an inclination acquisition unit 11 that acquires inclination at each sampling point set at predetermined distance intervals on a predetermined road indicated by road data, on the basis of the road data and altitude data; and a sloping road determination unit 12 that determines a start point or an end point in the road, on the basis of comparing a difference in inclination between a sampling point where an exponential moving average value of the inclination at each sampling point consecutively increases or starts decreasing, in both forward and backward direction of the predetermined road, and adjacent sampling points, with a predetermined threshold.SELECTED DRAWING: Figure 1 【課題】実走行することなく走行路における坂路の始点及び終点を検出して坂路区間を検出する。【解決手段】走行路データと標高データに基づき、前記走行路データが示す所定の走行路上に所定の距離間隔で設定された各サンプリング点の斜度を取得する斜度取得部１１と、前記所定の走行路の順方向と逆方向とで、前記サンプリング点毎の前記斜度の指数移動平均値が連続的に増加、又は、減少し始める前記サンプリング点とその前後の前記サンプリング点との前記斜度の差と、所定の閾値との比較に基づき、前記所定の走行路における坂路の始点又は終点を判定する坂路判定部１２と、を備える検出装置１０。【選択図】図１
