Abstract
A method for reducing noise generated from an electric oil pump (EOP) is reduced while driving a vehicle which has only the EOP without a mechanical oil pump (MOP) limits revolutions per minute (RPM) of the EOP to 70% or less of a maximum RPM during a low noise driving mode and rotates the EOP at the maximum RPM during a high noise driving mode.
