Abstract:
1. A method for use with an electric power steering (EPS) system, comprising the steps of: (a) measuring a vibration in a part of the EPS system, wherein the measured vibration includes periodic and non-periodic content and is measured by a sensor coupled to the part of the EPS system being vibrated; (b) identifying the periodic content of the measured vibration by evaluating the measured vibration over a number of wheel revolutions and extracting the periodic content from the non-periodic content of the measured vibration; (c) determining a vibration correction from the periodic content extracted from the non-periodic content of the measured vibration; and (d) driving an electric motor according to the vibration correction, wherein the vibration correction mitigates the effect of the measured vibration.
