PROBLEM TO BE SOLVED: To provide a road shape detection system configured to properly and quickly identify a road shape, on the basis of travel information of a vehicle which can be operated by automatic driving control, as well as manual operation, a road shape detection method, and a computer program.SOLUTION: A road shape detection system acquires travel information of a vehicle which is operated by automatic driving control or manual operation of an occupant, identifies whether the travel information has been obtained by automatic driving control or manual operation, for each travel information acquired, corrects the acquired travel information by weighting based on a travel mode, accumulates the corrected travel information as learning values, and identifies a curvature radius of a curve, on the basis of the accumulated learning values.SELECTED DRAWING: Figure 2

    【課題】手動運転に加えて自動運転制御による走行を行うことが可能な車両の走行情報に基づいて、道路形状を正確且つ迅速に特定することを可能にした道路形状検出システム、道路形状検出方法及びコンピュータプログラムを提供する。【解決手段】自動運転制御又は乗員の運転操作による手動運転のいずれかにより走行する車両の走行情報を取得し、取得した走行情報毎に、自動運転制御又は手動運転のどちらで走行した走行情報かを特定し、取得した走行情報に対して走行態様に応じた重み付けによる補正を行い、補正された走行情報を学習値として累積し、累積された学習値に基づいてカーブの曲率半径を特定するように構成する。【選択図】図2
