Beschreibung
Zusammenfassung:	A motor control apparatus and method for damping engine vibration are provided. The apparatus includes a data collection device that collects engine information and motor information and a processor that determines a magnitude of engine torque vibration using the engine information and the motor information. A weighting value is determined by determining a position of a piston in a cylinder of an engine, ignition timing, an engine angular acceleration, and an engine velocity. A motor arti-phase torque is calculated by reflecting the determined weighting value in the magnitude of the engine torque vibration and a motor is operated based on the motor anti-phase torque to cancel out the engine torque vibration.
