(FR) DISPOSITIF DE DIRECTION DE VÉHICULE
(JA) 車両用操向装置
Abstract
(EN)
When the vehicle speed Vs of a vehicle is a predetermined alternative vehicle speed, a target steering torque Tref is reduced in accordance with the absolute value of a difference between a physical quantity generated by a turning motion of the vehicle and an estimated value of the physical quantity at the alternative vehicle speed.
(FR)
Selon la présente invention, lorsque la vitesse d'un véhicule Vs d'un véhicule est une vitesse de véhicule alternative prédéterminée, un couple de direction cible Tref est réduit en fonction de la valeur absolue d'une différence entre une quantité physique générée par un mouvement de rotation du véhicule et une valeur estimée de la quantité physique à la vitesse de véhicule alternative.
(JA)
車両の車速Vsが所定の代替車速であるとき、車両の旋回運動によって発生する物理量と、代替車速における物理量の推定値との差分の絶対値に応じて、目標操舵トルクTrefを小さくする。
