Method for controlling an electric assist steering system

摘要

Process for controlling an electric power assisted steering system (1) comprises constantly determining an offset value from the steering angle theoretical value and a steering angle actual value and determining a virtual torque of the steering handle (3) based on the offset value. An independent claim is also included for an electric power assisted steering system. Preferred Features: The virtual torque of the handle is determined from the steering angle actual value, the angle of the drive (9) of the servomotor (2), the offset value and the rigidity of the electric power assisted steering system of the control and/or regulating device (4).
