摘要

The invention relates to a steering system comprising a control circuit for at least one steering actuator, and a control circuit for at least one steering wheel actuator, said steering wheel actuator being connected to the steering actuator by means of a control circuit. The control circuit of the steering wheel actuator comprises a pilot control (5) for improving the control quality of the torque on the steering handwheel during rapid steering movements. (47) A pre-determined steering wheel nominal moment (1) is converted into a torsion-bar nominal twisting angle (3) due to the rigidity of the torsion bar (2). A nominal moment is transmitted to an electric motor (6) via a control system (4) by means of a pilot control (5). A torsion-bar actual twisting angle (11) is produced by means of a steering column (10) via a gearbox (7) and in view of friction (8) and inertia (9), the actual twisting angle of said torsion bar being aligned with the torsion-bar nominal twisting angle (3).
