To improve safety of traveling of an own vehicle.SOLUTION: An inter-vehicle distance warning device mounted on an own vehicle determines whether or not a vehicle ahead contained in a front image of the own vehicle is traveling on the same lane as a traveling lane of the own vehicle or is traveling in a lane adjacent to the traveling lane of the own vehicle, assigns the preceding vehicle a coefficient of a different value depending on a result of determination of the lane, calculates a recommended inter-vehicle distance corresponding to the product of the coefficient and a total score of a score assigned to the vehicle ahead in the case where a traveling tendency of the vehicle ahead corresponds to a predetermined traveling tendency, a score assigned to the vehicle ahead in the case where a driver of the vehicle ahead is an elder person, a score assigned to the vehicle ahead in the case where the vehicle ahead includes an exterior appearance characteristic, and a score assigned to the vehicle ahead in the case where the vehicle ahead has a specified mark attached on it, and gives a warning indicating that it is necessary to increase an inter-vehicle distance between the own vehicle and the vehicle ahead in the case where the inter-vehicle between the own vehicle and the vehicle ahead is shorter than the recommended inter-vehicle distance.SELECTED DRAWING: Figure 1
【課題】自車両の走行の安全性を向上させる。【解決手段】自車両に搭載された車間距離警告装置は、自車両の前方の画像に含まれる先行車両が、自車両の走行レーンと同一のレーンを走行しているか、自車両の走行レーンに隣接するレーンを走行しているかを判定し、レーンの判定結果に応じて異なる値の係数を先行車両に付与し、先行車両の走行傾向が所定の走行傾向に該当する場合に先行車両に付与されるスコアと、先行車両の運転者が高齢者である場合に先行車両に付与されるスコアと、先行車両が外観的特徴を有する場合に先行車両に付与されるスコアと、先行車両に特定の標識が付されている場合に先行車両に付与されるスコアとの合計スコアと係数との積に対応する推奨車間距離を算出し、自車両と先行車両との車間距離が推奨車間距離より短い場合に、自車両と先行車両との車間距離を増加させる必要があることを示す警告を行う。【選択図】図1
