Abstract
Methods, systems, and devices for operating an engine controller in a vehicle for managing motor torque smoothing. One controller is configured to select a periodic disruptive waveform generated over a period of time to approximate that is associated with the vehicle being at idle, 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.
