(FR) PROCÉDÉ DE DÉTERMINATION D'UN COEFFICIENT DE FROTTEMENT POUR UN CONTACT ENTRE UN PNEUMATIQUE D'UN VÉHICULE ET UNE CHAUSSÉE ET PROCÉDÉ POUR COMMANDER UNE FONCTION DE VÉHICULE D'UN VÉHICULE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zum Bestimmen eines Reibwerts für einen Kontakt zwischen einem Reifen eines Fahrzeugs (102) und einer Fahrbahn. Das Verfahren weist einen Schritt des Verarbeitens von Sensorsignalen (140) auf, um verarbeitete Sensorsignale zu erzeugen. Dabei repräsentieren die Sensorsignale (140) mindestens von zumindest einer Erfassungseinrichtung (104, 106; 108) eingelesene, mit dem Reibwert korrelierbare Zustandsdaten. Die verarbeiteten Sensorsignale repräsentieren zumindest einen vorläufigen Reibwert. Das Verfahren weist auch einen Schritt des Ermittelns des Reibwerts unter Verwendung der verarbeiteten Sensorsignale und eines Regressionsmodells auf.
(EN) The invention relates to a method for determining a friction value for a contact between a tyre of a vehicle (102) and a road. The method involves a step of processing sensor signals (140) in order to generate processed sensor signals. The sensor signals (140) represent status data input at least by at least one detection device (104, 106, 108) and which can be correlated with the friction value. The processed sensor signals represent at least one provisional friction value. The method also involves a step of determining the friction value using the processed sensor signals and a regression model.
(FR) L'invention concerne un procédé de détermination d'un coefficient de frottement pour un contact entre un pneumatique d'un véhicule (102) et une chaussée. Le procédé comprend une étape de traitement de signaux de capteur (140) pour générer des signaux de capteur traités. À cet effet, les signaux de capteur (140) représentent au moins des données d'état lues par au moins un dispositif de détection (104, 106 ; 108) et corrélables avec le coefficient de frottement. Les signaux de capteur traités représentent au moins un coefficient de frottement préliminaire. Le procédé comprend également une étape de détermination du coefficient de frottement à l'aide des signaux de capteurs traités et d'un modèle de régression.
