Abstract
A controller, responsive to a signal indicating deactivation of a vehicle and disconnection of a traction battery from an inverter, generates a d-axis current command for the inverter having a ramp portion that defines a rate of change in current magnitude that depends on an electric angle between a rotor and stator of an electric machine.
