Title (EN) METHOD AND DEVICE FOR ESTIMATING ROLL ANGLE OF VEHICLE
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT D'ÉVALUER L'ANGLE DE ROULIS D'UN VÉHICULE
(JA) 車両のロール角推定方法及び装置
Abstract:
(EN) The roll stiffness coefficient (Kφ13) that is intrinsic to a vehicle is calculated from a first and second displacement and a first and second inner pressure value that were measured. The roll angle (φ2es) when an automatic height control was not executed is obtained on the basis of the calculated roll stiffness coefficient (Kφ13) (Kφ13new) and the displacement and inner pressure value measured at a given point after calculating the roll stiffness coefficient (Kφ13).
(FR) Le coefficient de rigidité au roulis (Kφ13) qui est propre à un véhicule est calculé à partir d'un premier et d'un second déplacement et d'une première et d'une seconde valeur de pression interne qui ont été mesurés. Quand aucun réglage automatique de la hauteur n'a été effectué, l'angle de roulis (φ2es) est obtenu sur la base du coefficient de rigidité au roulis (Kφ13) calculé (Kφ13new) ainsi que sur la base du déplacement et de la valeur de pression interne mesurés à un moment donné après le calcul dudit coefficient de rigidité au roulis (Kφ13).
(JA) 測定された第1及び第2の変位並びに第1及び第2の内圧値から、車両固有のロール剛性係数Kφ13を算出し、その後の任意の時点で測定された変位及び内圧値と上記算出したロール剛性係数Kφ13(Kφ13new)とに基づき、自動車高調整が行われなかった場合のロール角φ2esを求める。
