Abstract
An active electric motor damping (AEMD) control system for an electrified powertrain of a vehicle involves dynamically determining, based on a set of operating parameters of an electric motor, an AEMD torque boost voltage margin for a direct current to direct current (DC-DC) boost converter of the electrified powertrain, wherein the AEMD torque boost voltage margin is an additional voltage for increasing a torque capability of the electric motor, outputting, to the DC-DC boost converter, the AEMD torque boost voltage margin, wherein receipt of the AEMD torque boost voltage margin causes the DC-DC boost converter to boost a first voltage from a battery system of the electrified powertrain to a higher second voltage, and controlling the electric motor using the higher second voltage to dampen vibrations at a driveline of the vehicle.
