この判定がYesの場合は次のステップS13に進み、Noの場合は処理を終了する。
Y = aX + b (2)
なお、近似直線Aの算出にあたっては最小2乗法等の他の近似関数を求める方法を利用してもよい。
Y = −(1/a)X + c (3)
R=a・c
=XM+aYM (4)
なお、複数の静止物が検知されている場合は、各静止物の軌跡から対応する旋回半径Rが算出される。このように、本発明の一実施形態によれば、基本的にレーダからの検知情報のみに基づき自車両の旋回半径R、進行軌跡Tを推定(算出)することができる。
γ = V / R (5)
ちなみに単位は、R(m)、V(m/s)の場合γ(rad/s)となるので、γ(deg/s)を得るためには(5)式から得られるγ(rad/s)に180/πを乗算する。
