1. An engine controller in a vehicle for managing motor torque smoothing, the controller configured to:
select a periodic disruptive waveform generated over a period of time to approximate that is associated with the vehicle being at idle; and
determine a first harmonic sinusoid from a group of harmonic sinusoids that reduces the error between an approximated waveform and the disruptive waveform; and
initiate a supplemental quantity of torque during the period of time based on the disruption quantity of torque.
