Title
(DE) Regelstruktur für den Verstellmotor eines elektrischen Nockenwellenverstellers
(EN) Regulation structure for electric setting motor of electrically-driven camshaft adjuster for IC engine, has regulated required setting revs signal combined with unregulated revs signal
Abstract
(DE)

Die Erfindung betrifft eine Regelstruktur für den Verstellmotor (8) eines elektrischen Nockenwellenverstellers (6) eines Verbrennungsmotors (1) mit einem Regler (19), der Messsignale des Verbrennungsmotors (1) zu Steuerdaten für den Verstellmotor (8) verarbeitet. DOLLAR A Ein Regler (19), der auch bei einem Nullwert des Eingangs-Differenzsignals sinnvolle Werte für die Sollverstelldrehzahl des Verstellmotors (8) aufweist, wird dadurch erreicht, dass dem Ausgangssignal (20) einer geregelten Solldrehzahl das Signal einer ungeregelten Drehzahl (21) aufgeschaltet wird.

(EN)

The regulation structure has at least one regulator (19), e.g. a PID regulator, responding to measured signals for the IC engine for providing control signals for the electric setting motor of the camshaft adjuster. The regulator is supplied at its input with the difference signal between actual and required setting angle values (17,18), the output signal provided as a regulated required setting revs signal (20), to which an unregulated revs signal (21) is added.
