Title (EN) METHOD FOR ANALYSING AND/OR AT LEAST PARTIALLY COMPENSATING STEERING WHEEL TORSIONAL VIBRATIONS
(FR) PROCÉDÉ D'ANALYSE ET/OU DE COMPENSATION AU MOINS PARTIELLE D'OSCILLATIONS DE TORSION DU VOLANT
(DE) VERFAHREN ZUR ANALYSE UND/ODER ZUR ZUMINDEST TEILWEISEN KOMPENSATION VON LENKRADDREHSCHWINGUNGEN
Abstract:
(EN) The invention is based on a method for analysing and/or at least partially compensating steering wheel torsional vibrations, particularly during operation of a steering device in a vehicle (10, 20), wherein at least one sensing signal (12) is acquired and at least one interference characteristic variable (14) which is correlated to the steering wheel torsional vibration is extracted from the sensing signal (12). It is proposed that during a monitoring time interval a change over time in the interference characteristic variable (14) and a change over time in a wheel frequency (16) which is correlated to a current wheel rotational speed characteristic variable is monitored and said changes are combined in order to analyse and/or to at least partially compensate steering wheel torsional vibrations to form a common evaluation dataset (18, 20).
(FR) L'invention concerne un procédé d'analyse et/ou de compensation au moins partielle d'oscillations de torsion du volant, en particulier pendant le fonctionnement d'un dispositif de direction d'un véhicule (10, 12). Selon le procédé, au moins un signal de détection (12) est détecté et au moins une grandeur caractéristique perturbatrice (14) en corrélation avec l'oscillation de torsion du volant est extraite du signal de détection (12). Selon l'invention, un changement temporel de la grandeur caractéristique perturbatrice (14) et un changement temporel d'une fréquence de roue (16) en corrélation avec une grandeur caractéristique de vitesse de roue actuelle sont surveillés et combinés pour constituer un ensemble commun de données d'évaluation (18, 20) aux fins d'analyse et/ou de compensation au moins partielle d'oscillations de torsion du volant pendant un intervalle de temps de surveillance.
(DE) Die Erfindung geht aus von einem Verfahren zur Analyse und/oder zur zumindest teilweisen Kompensation von Lenkraddrehschwingungen, insbesondere während eines Betriebs einer Lenkvorrichtung in einem Fahrzeug (10, 12), wobei zumindest ein Erfassungssignal (12) erfasst und aus dem Erfassungssignal (12) wenigstens eine mit der Lenkraddrehschwingung korrelierte Störkenngröße (14) extrahiert wird. Es wird vorgeschlagen, dass während eines Überwachungszeitintervalls eine zeitliche Veränderung der Störkenngröße (14) und eine zeitliche Veränderung einer mit einer aktuellen Raddrehzahlkenngröße korrelierten Radfrequenz (16) überwacht und zur Analyse und/oder zur zumindest teilweisen Kompensation der Lenkraddrehschwingungen zu einem gemeinsamen Auswertedatensatz (18, 20) zusammengefasst werden.
