Title
(DE) VORRICHTUNG ZUR FAHRBAHNABHÄNGIGEN FAHRWERKSREGELUNG

Abstract
(DE)
Vorrichtung zur fahrbahnabhängigen Fahrwerksregelung eines Fahrzeugs, insbesondere eines Kraftfahrzeugs, mit den dynamischen Fahrzustand erfassenden Sensoren, deren Daten einer Auswerteschaltung zugeführt werden, die ein für die Fahrbahnunebenheit charakteristisches Signal erzeugt und mit einer Federanordnung des Fahrzeugs zusammenwirkende Aktuatoren steuert. Es wird vorgeschlagen, daß die Auswerteschaltung für jedes Rad den Momentanwert der dort vorliegenden Fahrbahnunebenheit (S) und/oder Fahrbahn-Unebenheitsgeschwindigkeit (S) aus den Daten der in jedem Radbereich angeordneten Sensoren ermittelt und dem jedem Rad zugehörigen Regelkreis als aktuelle Größe zuführt.
(EN)
Disclosed is a device for controlling the chassis, as a function of the road surface, of a vehicle, in particular a motor vehicle. The device comprises sensors which determine the dynamic running status, the data from the sensors being fed to a processing circuit which generates a signal characteristic of the unevenness of the road surface and controls actuators acting on the vehicle suspension. It is proposed that, for each wheel, the instantaneous value of the road-surface unevenness (S) and/or the speed on road-surface unevenness (S) be determined from the data supplied by the sensors in each wheel region and this value supplied as an actual variable to the control circuit associated with each wheel.
(FR)
Dispositif pour la régulation, en fonction de la chaussée, du chassis d'un véhicule, en particulier d'un véhicule automobile, comportant des capteurs détectant l'état de marche dynamique, les signaux desdits capteurs étant amenés à un circuit d'évaluation qui génère un signal caractéristique pour l'inégalité de la chaussée et qui commande des actuateurs coopérant avec un agencement de ressorts du véhicule. Il est proposé que le circuit d'évaluation détermine pour chaque roue la valeur instantanée de la déformation de la chaussée (S) et/ou de la vitesse sur chaussée déformée (S) sur la base des données des capteurs disposés dans chaque région de roue et l'amène sous forme de grandeur actuelle au circuit régulateur apppartenant à chaque roue.
