Title (EN) METHOD AND DEVICE FOR CALCULATING MAGNITUDE OF CORNERING FORCE GENERATED IN WHEEL
(FR) PROCÉDÉ ET DISPOSITIF POUR LE CALCUL DE L’AMPLITUDE DE LA FORCE DE DÉRIVE GÉNÉRÉE DANS UNE ROUE
(JA) 車輪に発生するコーナリングフォースの大きさを算出する方法および装置
Abstract:
(EN) A method for calculating the magnitude of a cornering force generated in each of wheels, comprising the steps of obtaining the magnitude of a centrifugal force in an approximately vertical direction to the advancing direction of a vehicle applied to the vehicle during turning, and the ground-contact length of each of the plurality of wheels and the deformed amount of each of the wheels at each of the ground-contact portions of the plurality of wheels in the wheel width direction while the vehicle is turning, calculating a differences between the deformed amount of each of the wheels in the lateral direction and the deformed amount of each of the wheels in the lateral direction while the vehicle is traveling straightforward, and calculating the magnitude of the cornering force generated in each of the wheels by using the magnitude of the centrifugal force, the ground-contact length, and the difference of the deformed amount in the lateral direction.
(FR) Cette invention se rapporte à un procédé de calcul de l’amplitude d’une force de dérive générée dans chacune des roues, comprenant les étapes d’obtention de l’amplitude de la force centrifuge dans une direction approximativement verticale dans le sens de la marche d’un véhicule appliquée au véhicule qui tourne, et la longueur du contact avec le sol de chacune des roues ainsi que la quantité déformée de chacune des roues à chacune des parties en contact avec le sol des roues dans la direction de la largeur tandis que le véhicule tourne, en calculant une différence entre la quantité déformée de chacune des roues dans la direction latérale tandis que le véhicule se déplace en ligne droite et en calculant l’amplitude de la force de dérive générée dans chacune des roues en utilisant l’amplitude de la force centrifuge, la longueur de contact avec le sol et la différence de la quantité déformée dans la direction latérale.
(JA)  旋回走行中の車両にかかる、車両進行方向に対して略垂直方向の遠心力の大きさと、車両の旋回走行中における複数の車輪それぞれの接地長と、複数の車輪の接地部分それぞれの車輪幅方向の変形量とを求め、さらに、各車輪の幅方向の変形量それぞれの、車両の直進走行中における各車輪幅方向の変形量に対する差分をそれぞれ算出して、前記遠心力の大きさ、前記接地長、および前記幅方向変形量の差分を用いて、各車輪に発生するコーナリングフォースの大きさをそれぞれ算出する。
