- 車両の前方道路を監視するセンサー部、及び
道路周辺にある連続した静止物を感知して仮想ラインを算出し、前方道路で感知された先行車両横位置の絶対値が仮想ライン横位置の絶対値より大きいと判断されれば、以前に感知された先行車両横位置を現在先行車両横位置として認識する制御部、を含み、
前記仮想ラインは、センサー部で感知された静止物を算出してグループに選定し、選定された静止物グループを相対距離値によって整列し、整列された静止物グループ座標を1次線形補間することにより算出し、
前記選定された静止物グループの横位置平均値を計算し、静止物グループの横位置と平均値の差の絶対値が第1基準値より大きければ静止物グループは削除されることを特徴とする前方車両感知システム。
- 前記感知された静止物の算出は、相手車速絶対値と自車速絶対値の差が第2基準値より小さい条件で算出されることを特徴とする請求項1に記載の前方車両感知システム。
- 前記静止物グループの選定は、静止物の相対距離の差の絶対値が第3基準値より小さく、静止物の横位置の差の絶対値が第4基準値より小さい条件で選定されることを特徴とする請求項1に記載の前方車両感知システム。
