Abstract

See full text

The system and method described herein can be used to reduce the effects of periodic vibrations in an electric power steering (EPS) system for a vehicle, particularly, those that can lead to smooth road shake (SRS), torsional nibble, and/or other undesirable conditions. According to an exemplary embodiment, an electric motor is used to purposely generate counter-acting vibrations in the EPS system to cancel out the periodic vibrations generated by the wheel assemblies or corners.
