Abstract
(DE)
Die Erfindung betrifft ein Kraftfahrzeug (10) zum Ermitteln eines Fahrbahnprofils, wobei zunächst ein auf der Fahrspur des Kraftfahrzeugs (10) vorausfahrendes Fahrzeug erkannt wird. Ferner wird eine Trajektorie zumindest eines Fixpunkts des vorausfahrenden Fahrzeugs erfasst und anhand eines inversen Fahrzeugmodells und der erfassten Trajektorie des zumindest einen Fixpunkts des vorausfahrenden Fahrzeugs ein Fahrbahnhöhenprofil ermittelt. Bevorzugt werden ferner ein horizontaler Abstand zu dem vorausfahrenden Fahrzeug und eine Eigengeschwindigkeit des Kraftfahrzeugs (10) erfasst. Anhand des ermittelten Fahrbahnhöhenprofils, des erfassten horizontalen Abstands und der Eigengeschwindigkeit erfolgt ferner bevorzugt eine Vorsteuerung eines adaptiven Dämpfersystems (60).
(EN)
The invention relates to a motor vehicle (10) for determining a roadway profile, wherein first a vehicle driving ahead in the lane of the motor vehicle (10) is detected. A trajectory of at least one fixed point of the vehicle driving ahead is then detected and, using an inverse vehicle model and the detected trajectory of the at least one fixed point of the vehicle driving ahead, a roadway elevation profile is determined. Preferably, a horizontal distance from the vehicle driving ahead and a speed of the motor vehicle (10) are also detected. Using the determined roadway elevation profile, the detected horizontal distance and the speed, feedforward control of an adaptive damper system (60) is preferably also carried out.
(FR)
L'invention concerne un véhicule automobile (10) destiné à déterminer un profil de chaussée, un véhicule qui précède sur la voie de circulation du véhicule automobile (10) étant tout d'abord détecté. Une trajectoire d'au moins un point fixe du véhicule qui précède est en outre détectée et un profil de hauteur de la chaussée est déterminé à l'aide d'un modèle inverse du véhicule et de la trajectoire détectée dudit point fixe du véhicule qui précède. Une distance horizontale par rapport au véhicule qui précède et la vitesse propre du véhicule automobile (10) sont de préférence également acquises. Une commande pilote d'un système d'amortissement adaptatif (60) est en outre réalisée de préférence à l'aide du profil de hauteur déterminé de la chaussée, de la distance horizontale détectée et de la vitesse propre.
