ABSTRACT:
Internal combustion engine torque control for damping undesirable engine speed variation measures the variation as a high frequency engine speed variation at a known engine operating angle and, for each cylinder combustion event while the variation is present, calculates a phase-compensated desired torque change to dampen the engine speed variation by projecting the engine speed variation phase at the known engine operating angle to the phase at a next combustion event, and to calculate an opposing cylinder output torque change to dampen the engine speed variation phase at that next combustion event. The torque change is then carried out through ignition timing variation at the combustion event or through variation in the amount of fuel delivered for ignition at the combustion event.
