Description
また、判定距離設定手段は、予想進路からの判定距離を、物体検出手段が検出した車両に対する物体の位置から求めた物体との距離の増加に応じて長くなるように設定してもよい。
次に、ECU5が実行する処理について、図3のフローチャートに基づいて説明する。本処理は、所定時間毎に実行される。ECU5は先ず、車速センサ2が検出した車速Vと回転角速度センサ3が検出したヨーレートYaw及び物体検出センサ4が検出した車両1と物体との相対速度RV、距離L及び位置データTGDを取得する(ステップS1)。
ここで、α及びβは所定の係数である。
2:車速センサ(車両情報検出手段)
3:回転角速度センサ(車両情報検出手段)
4:物体検出センサ(物体検出手段)
5:ECU(進路推定手段、前方車判別手段、判定距離設定手段、先行車検知手段)
6:ブレーキアクチュエータ
7:スロットルアクチュエータ
8:表示器
Claims (1)
- 追従対象として設定可能な先行車を検知するために車両に搭載される先行車検知装置であって、
前記車両の進行方向の前方に存在する物体を検知し、前記物体と前記車両との相対速度及び前記車両に対する前記物体の位置を検出する物体検出手段と、
前記車両の走行状態情報を検出する車両状態検出手段と、
前記車両情報検出手段が検出した走行状態情報に基づいて、前記車両の予想進路を推定する進路推定手段と、
前記物体検出手段が検出した相対速度と前記車両情報検出手段が検出した走行状態情報とに基づいて、前記物体が前記車両と同方向へ走行する前方車両であるか否かを判別する前方車両判別手段と、
前記予想進路からの判定距離を設定する判定距離設定手段と、
前記物体が前記前方車両であると前記前方車両判別手段が判別したとき、前記物体検出手段が検出した前記物体の位置と前記予想進路との距離が前記判定距離以下であるか否かを判定し、前記判定距離以下であると判定した物体を前記先行車として検知する先行車検知手段と、を備え、
前記判定距離設定手段は、前記物体が前記前方車両であると前記車両判別手段が判別したとき、前記車両に対して前記物体が遠ざかるか否かを前記物体検出手段の検出結果を用いて判定し、前記車両に対して前記物体が遠ざかると判定した場合、前記車両からの前記物体の離間速度が速いほど前記判定距離が短くなるように、前記物体検出手段が検出した相対速度の増加に応じて前記判定距離を短く設定する
ことを特徴とする先行車検知装置。
