Abstract

The sound generated by a brushless motor-assisted steering system is examined. The objective of the study is to determine the acceptable levels of in-vehicle structure-borne induced noise and airborne radiated noise contributors relative to the current baseline system. It is shown that acceptable electric power steering levels allow tradeoffs between structure-borne and airborne noise sources. Changes in electric motor structure-borne and airborne sound levels are highly correlated to jury acceptable results.
