Title
(DE) FAHRWERKSREGELUNG MIT STELLGLIED-ANPASSSCHALTUNG
(EN) CHASSIS CONTROL WITH SERVO-ADJUSTMENT CIRCUIT
(FR) REGULATION DU CHASSIS AVEC CIRCUIT D'ADAPTATION A ELEMENT DE REGLAGE
Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung zur Fahrwerksregelung von Fahrzeugen, insbesondere von Personen- und Nutzfahrzeugen, mit den Fahrzustand erfassenden Sensoren, deren Daten einem Regler zugeführt werden, der einen semiaktiven, mit einer Federanordnung zusammenwirkenden Dämpfer steuert. Für die Anwendung bekannter Reglerentwurfs- und -optimierungsverfahren wird eine zwischen den Regler und den Dämpfer (2) geschaltete, der Anpassung der nichtlinearen Steuerkennlinie des Dämpfers (2) an die lineare Steuerspannung des Reglers dienende Kompensationsschaltung vorgeschlagen.
(EN)
The invention concerns a device for regulating the chassis of vehicles, in particular passenger cars and utility vehicles. The device has sensors which determine the vehicle running status, the data from the sensors being fed to a control unit which controls a semi-active shock absorber working in conjunction with a spring unit. In order to be able to make use of existing control unit design and optimization procedures, a compensation circuit is proposed which is located between the control unit and the shock absorber (2) and the purpose of which is to adapt the non-linear control characteristics of the shock absorber (2) to the linear control voltage of the control unit.
(FR)
L'invention se rapporte à un dispositif pour la régulation du châssis de véhicules, en particulier de voitures particulières et utilitaires, comportant des capteurs détectant l'état de marche, les données desdits capteurs étant amenées à un régulateur qui commande un amortisseur semi-actif coopérant avec un agencement de ressorts. Pour l'application de procédés connus de mise au point et d'optimisation de régulateurs, il est proposé un circuit de compensation inséré entre le régulateur et l'amortisseur (2), servant à l'adaptation de la caractéristique de réglage automatique non linéaire de l'amortisseur (2) à la tension de commande linéaire du régulateur.
