Patent ID: 7044046

Claim:
A hydraulic servo-assisted steering system for a motor vehicle, comprising: an electro-hydraulic converter; a steering-force-assisting servo actuator; a controller; and a hydraulic steering valve configured to control, as a function of torque and speed superimposed by the controller, hydraulic loading of the steering-force-assisting servo actuator by the electro-hydraulic converter; wherein the steering valve includes a set valve characteristic curve corresponding to a set steering behavior of the steering system, the electro-hydraulic converter including an actuating magnet configured to energize the steering valve in a manner oriented to the set valve characteristic curve, at least one of (a) the controller, (b) the electro-hydraulic converter, and (c) the actuator configured to store a plurality of energization characteristic curves assigned to the actuating magnet, an energization characteristic curve adapted to correct deviation of a respective actual valve characteristic curve from the set valve characteristic curve corresponding to the set steering behavior being connectable.
