Title (EN) VEHICLE MOTION STATE ESTIMATION APPARATUS
(FR) APPAREIL D'ESTIMATION D'ÉTAT DE MOUVEMENT DE VÉHICULE
(JA) 車両運動状態推定装置
Abstract:
(EN) The present invention addresses the problem of providing a vehicle motion state estimation apparatus that is capable of highly accurately estimating the vertical motion amount of a vehicle on the basis of a wheel speed sensor signal during traveling such as acceleration/deceleration or turning where a longitudinal or horizontal wheel slippage occurs. According to the present invention, a fluctuation component generated due to the displacement of suspension is gleaned by estimating and removing a fluctuation component generated due to wheel slippage on the basis of the fluctuation component of the wheel speed sensor signal, and the vertical motion amount of the vehicle is estimated on the basis of the gleaned fluctuation component generated due to the displacement of the suspension.
(FR) La présente invention concerne un appareil d'estimation d'état de mouvement de véhicule, qui est capable d'estimer avec une grande précision la valeur de mouvement vertical d'un véhicule sur la base d'un signal de capteur de vitesse de roues pendant un déplacement tel qu'une accélération/décélération ou un virage, pendant lesquels un dérapage longitudinal ou horizontal des roues se produit. Selon la présente invention, une composante de fluctuation générée en raison du déplacement de la suspension est obtenue par l'estimation et l'élimination d'une composante de fluctuation, générée en raison d'un dérapage des roues sur la base de la composante de fluctuation du signal de capteur de vitesse de roues, et la valeur de mouvement vertical du véhicule est estimée sur la base de la composante de fluctuation obtenue ayant été générée en raison du déplacement de la suspension.
(JA) 本発明の課題は、前後、横方向の車輪スリップが生じる加減速や旋回などの走行時において、車輪速センサ信号から車両の上下運動量を高精度に推定できる車両運動状態推定装置を提供することである。本発明は、車輪速センサ信号の変動成分から車輪スリップによって生じる変動成分を推定、除去することでサスペンションの変位によって生じる変動成分を抽出し、抽出したサスペンションの変位によって生じる変動成分から車両の上下運動量を推定する。
