To prevent or suppress the lowering of the recognition accuracy of a road shape even if a recognition distance of the road shape is long.SOLUTION: There is provide a road shape recognition device 10. The road shape recognition device 10 comprises: a feature point acquisition part 103 for acquiring a plurality of feature points indicating a road shape at preset timing; and a road shape determination part 101 for dividing a recognition distance of the road shape into a plurality of zones by a preset zone distance, creating zone road shape lines at respective zones by using a current feature point which is acquired at current timing, and the past feature point which has been acquired at the past timing, and determining the road shape by connecting the created zone road shape lines, being the road shape determination part 101 for creating the zone road shape lines by using an average feature point which is obtained by averaging a position of the current feature point and a position of the past feature point when the position of the current feature point and the position of the past feature point are within a preset distance range.SELECTED DRAWING: Figure 2

    【課題】道路形状の認識距離が長い場合であっても、道路形状の認識精度の低下を防止または抑制する。【解決手段】道路形状認識装置10が提供される。道路形状認識装置10は、予め定められたタイミングにて、道路形状を示す複数の特徴点を取得する特徴点取得部103と、道路形状の認識距離を予め定められた区分距離で複数の区間に分割し、現在のタイミングで取得された現在特徴点および過去のタイミングで取得された過去特徴点を用いて前記区間毎に区間道路形状線を生成し、生成した区間道路形状線を接続して道路形状を決定する道路形状決定部101であって、現在特徴点の位置と過去特徴点の位置が予め定められた距離範囲内にある場合には、現在特徴点の位置と過去特徴点の位置とを平均化した平均特徴点を用いて区間道路形状線を生成する道路形状決定部101とを備える。【選択図】図2
