Title (EN) CURVE RADIUS ESTIMATION DEVICE
(FR) DISPOSITIF D'ESTIMATION DU RAYON D'UNE COURBE
(JA) カーブ半径推定装置
Abstract:
(EN) A curve radius estimation device (100) for estimating the curve radius of a lane in which a vehicle travels comprises a first curve radius calculating means (110) for calculating a first curve radius from a steering angle, a second curve radius calculating means (111) for calculating a second curve radius from a yaw rate, and a curve radius estimating means (112) for estimating the curve radius by combining the first curve radius and the second curve radius at a predetermined combination ratio, and the curve radius estimating means (112) changes the predetermined combination ratio according to the vehicle speed.
(FR) L'invention concerne un dispositif d'estimation du rayon d'une courbe (100) pour estimer le rayon de la courbe d'une voie sur laquelle se déplace un véhicule, comprenant des premiers moyens de calcul du rayon de la courbe (110) pour calculer un premier rayon de courbe à partir d'un angle de direction, des deuxièmes moyens du calcul du rayon de la courbe (111) pour calculer un deuxième rayon de courbe à partir d'un taux de lacet et des moyens d'estimation du rayon de la courbe (112) pour estimer le rayon de la courbe en combinant le premier rayon de courbe et le deuxième rayon de courbe à un rapport de combinaison prédéterminé. Selon l'invention, les moyens d'estimation du rayon de la courbe (112) modifient le rapport de combinaison prédéterminé en fonction de la vitesse du véhicule.
(JA)  自車両が走行する車線のカーブ半径を推定するカーブ半径推定装置(100)は、操舵角に基づいて第一カーブ半径を算出する第一カーブ半径算出手段(110)と、ヨーレートに基づいて第二カーブ半径を算出する第二カーブ半径算出手段(111)と、第一カーブ半径と第二カーブ半径とを所定の合成比で合成してカーブ半径を推定するカーブ半径推定手段(112)と、を備え、カーブ半径推定手段(112)は、車速に応じて前記所定の合成比を変化させる。
