摘要
The invention relates to a method for operating an electric power steering system, an electronic control unit for an electric power steering system and an electric power steering system. According to the invention, the method for operating an electric power steering system having an electronic control unit (20) for controlling of an electric power applied to an electric motor (22), which electric motor (22) generates assist torque for an assisting steering system, said assist torque or compensation torque being computed by means of an algorithm, comprises the steps of determination of an disturbance torque signal related to internal and external forces acting on the electric power steering system, estimation of an amplitude of the disturbance torque signal, classification of the amplitude of the disturbance torque signal, computation of an compensation torque dependent on the classification and the amplitude of the disturbance torque signal and at least partial compensation of the disturbance torque by supply of electric power to the electric motor (22) in accordance with the computed compensation torque.
