Abstract

Ein Hilfskraftlenkungssystem weist eine reversible Pumpe (6) zur Zufuhr von Hydraulikflüssigkeit zu den Druckkammern eines Antriebszylinders (5a) durch erste und zweite Leitungen, einen Unterstützungskraft-Detektor zum Ermitteln einer Lenkungsunterstützungskraft, mit der ein Lenkrad (1) zu versehen ist, einen Motorsteuerungsschaltkreis, der ein Antriebssignal an einen Elektromotor (6a) gemäß der ermittelten Lenkungsunterstützungskraft sendet, um somit einen gewünschten Hydraulikdruck zu erhalten, eine Verbindungsleitung zum Schaffen einer Flüssigkeitsverbindung zwischen der ersten und zweiten Leitung, ein Magnetventil (4) zum Schalten zwischen einer Verbindung und Unterbrechung der Verbindungsleitung und einen Stromdetektor zum Ermitteln eines Stroms, der durch einen Erregerschaltkreis des Magnetventils (4) und zwischen dem Magnetventil (4) und einer Erdung fließt, auf.
