Abstract:
(EN) A vehicle behavior controller realizing yaw control corresponding to the actual vehicle behavior and enabling reduction of feeling of strangeness of steering which the driver has. The relation between the lateral acceleration and the target instantaneous yaw gain which is a target value of the degree of variation of the yaw rate/steering angle is used to determine a target yaw rate which is a control target of the yaw rate. The relation includes a characteristic that “the target instantaneous yaw gain near the upper and lower ends of the codomain of the lateral acceleration is smaller than the target instantaneous yaw gain in the codomain outside the ranges near the upper and lower ends of the codomain of the lateral acceleration”.
(FR) L'invention porte sur un dispositif de commande de comportement de véhicule qui exécute une commande de lacet correspondant au comportement réel du véhicule et qui permet une réduction de la sensation d'étrangeté de direction que ressent le conducteur. On utilise la relation entre l'accélération latérale et le gain de lacet instantané cible, qui est une valeur cible du degré de variation de l'angle de direction/vitesse de lacet, pour déterminer une vitesse de lacet cible qui est une cible pour la commande de la vitesse de lacet. La relation comprend une caractéristique selon laquelle « le gain de lacet instantané cible à proximité des extrémités supérieure et inférieure du co-domaine d'accélération latérale est inférieur au gain de lacet instantané cible dans le co-domaine extérieur aux plages à proximité des extrémités supérieure et inférieure du co-domaine d'accélération latérale ».
(JA)  実際の車両挙動に沿ったヨー制御が実現でき、その結果ドライバーの操舵の違和感を低減することができる車両挙動制御装置を提供することを課題とする。本発明は、ヨーレート/操舵角の変化の度合いの目標値である目標瞬間ヨーゲインと横加速度との関係であって"横加速度の変域の上端近傍及び下端近傍での目標瞬間ヨーゲインが上端近傍及び下端近傍以外の変域での目標瞬間ヨーゲインに対して小さい"という特性を含むものに基づいて、ヨーレートの制御目標である目標ヨーレートを設定する。
