Description
前記第1検出範囲よりも自車に近い第2検出範囲内の障害物情報を取得する第2センサと、
前記第1センサ及び前記第2センサからの障害物情報に基づいて、障害物に対する衝突防止又は衝突時の被害軽減に関連する所定制御を実行する処理装置とを含み、
前記処理装置は、前記第1センサからの障害物情報に基づいて前記所定制御を開始した後、前記第1センサ及び前記第2センサにより前記障害物が検出されない場合に、前記障害物の所定部位と前記第1検出範囲又は前記第2検出範囲との高さ方向の位置関係を表す位置関係情報を用いて、前記所定制御を継続するか否かを判断する、車載制御装置が提供される。
t≦GMAX/Jのとき、G=Jt、V=J×t2/2
GMAX/J<tのとき、G=GMAX、V=GMAX 2/(2J)+GMAX(t−GMAX/J)
この場合、t秒後の減速速度Vよりも大きい相対速度を衝突不可避な相対速度とみなして、衝突不可避判定マップを作成してもよい。或いは、減速速度Vを積分することにより相対距離を求めることで、相対距離をパラメータとした衝突不可避判定マップを作成してもよい。或いは、更に複雑なアルゴリズムとして、前方障害物の加速度等が考慮されてもよい。
