Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zur Einstellung des Steuerwinkels mindestens eines lenkbaren Rades eines Fahrzeugs, mit Sensormitteln zur Erfassung des Einschlagwinkels eines Lenkrades des Fahrzeugs und mit einem Regler, der in Abhängigkeit von einem von der Fahrgeschwindigkeit und dem Einschlagwinkel abhängigen Sollwert den durch Lenkradverstellung erzeugten Steuerwinkel des Rades korrigierend nachführt. Sie zeichnet sich durch eine Sollwert-Anpass-Schaltung (13) aus, die eine ein neutrales oder untersteuerndes Verhalten des Fahrzeugs (2) erzeugende Bewertungsstufe (24) und/oder eine dynamische Zeitfunktionsstufe (25) aufweist.
(EN)
A device for adjusting the steering angle of at least one steerable wheel of a vehicle comprises sensors which measure the angle of deflection of the steering wheel of the vehicle and a regulator which corrects the angle of deflection of the wheel produced by the movement of the steering wheel in function of a reference value which depends on the speed of the vehicle and on the angle of deflection. An adaptative circuit (13) for the reference value comprises an evaluation stage (24) which causes the vehicle (2) to behave in a neutral or understeered manner and/or a dynamic time-function stage (25).
(FR)
Un dispositif de réglage de l'angle de braquage d'au moins une roue orientable d'un véhicule comprend des capteurs de saisie de l'angle de braquage du volant d'un véhicule et un régulateur qui corrige l'angle de braquage de la roue obtenu par le déplacement du volant en fonction d'une valeur de consigne dépendante de la vitesse du véhicule et de l'angle de braquage. Un circuit adaptatif (13) de la valeur de consigne comprend un étage d'évaluation (24) qui génère un comportement neutre ou sous-vireur réduit du véhicule, et/ou un étage dynamique de fonction temps (25).
