Abstract
An electric power steering (EPS) system and methods to attenuate disturbances at the steering wheel by providing a feed forward motor drive input. The EPS includes an electric motor configured to provide a motor drive output responsive to a motor drive input, and an electronic control unit (ECU) being configured to provide the motor drive input, with at least one motor drive component of the motor drive input including compensatory periodic disturbance data. The ECU is further configured to provide disturbance attenuation with the at least one motor drive component from a road wheel signal and vibratory characteristics of a disturbance signal affecting the steering system.
