Methods and systems are provided for suppression of steering wheel vibrations generated by periodic disturbances in a vehicle steering system. An exemplary method reducing steering wheel vibrations caused by periodic disturbances involves determining a gross torque attributable to the periodic disturbances in the steering system, identifying a desired amount of suppression of the vibrations at the steering wheel, determining an offset torque based on the gross torque and the desired amount of suppression, and generating a motor command signal in a manner that is influenced by the offset torque. The motor drive command signal is provided to an electric motor coupled the steering wheel and/or the vehicle tires, and the motor drive command signal influences the torque applied by the motor to assist steering of the vehicle tires by the steering wheel in a manner that attenuates the vibrations communicated to the steering wheel by the desired amount.
