Abstract

Vorgeschlagen werden ein Verfahren und danach arbeitende Vorrichtungen, insbesondere eine Schaltung (ESK), die ein Kompensationssignal (KS) durch eine faktorisierte Addition zweier sinusförmiger Signale (sin1, sin2) erzeugt. Dabei wird ausgenutzt, dass bei einer elektrischen Hilfskraftlenkung bereits sinusförmige Antriebsströme (Iu, Iv, Iw) zur Verfügung stehen und dass die Addition phasenverschobener Sinussignale mit derselben Frequenz, wieder ein Sinussignal mit dieser Frequenz ergibt. Die Signale (sin1, sin2) werden vor der Addition mit Faktoren (F1, F2) multipliziert, wodurch die Phasenlage des resultierenden Sinussignals bzw. Summensignals am Ausgang des Addierers (A1) verschoben werden. Diese Summensignal wird dann mit einem Faktor (F3) multipliziert, der sowohl der Amplitudennormierung wie auch Anpassung an das Störfeld entspricht, um schließlich ein sinusförmiges Kompensationssignal (KS) mit vorgebbarer Phasenlage und mit normierter sowie auf das Störfeld hin optimierter Amplitude zu erhalten. Das Kompensationssignal (KS) wird dann von dem gestörten Sensorsignal (HS) subtrahiert.
