Title (EN) ROAD SURFACE FRICTION COEFFICIENT ESTIMATING DEVICE AND ROAD SURFACE FRICTION COEFFICIENT ESTIMATING METHOD
(FR) DISPOSITIF ET PROCÉDÉ D’ESTIMATION DU COEFFICIENT DE FROTTEMENT DE LA SURFACE D’UNE ROUTE
(JA) 路面摩擦係数推定装置及び路面摩擦係数推定方法
Abstract:
(EN) A road surface friction coefficient estimating device includes a braking/driving force detecting section for detecting the braking/driving force of a wheel during traveling, a slip ratio detecting section for detecting the slip ratio of the wheel during traveling, and a road surface μ calculating section for estimating the relationship between the detected braking/driving force and the detected slip ratio on the basis of the ratio between the detected braking/driving force and the detected slip ratio, the correlation between the braking/driving force and the slip ratio in the case of the reference road surface, and at least either the detected braking/driving force or the detected slip ratio.
(FR) L'invention concerne un dispositif d’estimation du coefficient de frottement de la surface d’une route, comprenant une section de détection de la force résistante / motrice servant à détecter la force résistante / motrice d’une roue en cours de circulation, une section de détection du taux de glissement servant à détecter le taux de glissement de la roue en cours de circulation, et une section de calcul du coefficient de frottement μ de la surface de la route servant à estimer la relation entre la force résistante / motrice détectée et le taux de glissement détecté sur la base du rapport entre la force résistante / motrice détectée et le taux de glissement détecté, de la corrélation entre la force résistante / motrice et le taux de glissement dans le cas de la surface routière de référence, et au moins de la force résistante / motrice détectée ou du taux de glissement détecté.
(JA)  路面摩擦係数推定装置は、走行時の車輪の制駆動力を検出する制駆動力検出部と、走行時の車輪のスリップ率を検出するスリップ率検出部と、検出した制駆動力とスリップ率との比、基準路面について車輪の制駆動力と車輪のスリップ率との相関関係、並びに検出した制駆動力及び検出したスリップ率の少なくとも一方を基に、該制駆動力と該スリップ率との関係を推定する路面μ算出部と、を備える。
