In the previous paper, the effectiveness of an active electric torque control method in reducing vehicle idling vibration reduction was proposed. In this paper, the influence of the control torque waveform on this control is analyzed theoretically and experimentally with the goal of improving control considering limitations on the torgue control devices. Torque harmonic analysis shows that the control torque waveform can be used to maximize the amplitude of the firing frequency component which cancels engine torque variation and to minimize the average torque which increases the engine load and torque variation. Sine and rectangular waves are investigated as possible control torque waveforms. When the ratio of the device's torque generation and absorption is small, the influecne of the load torque increase due to control is significant, and the sine wave produces better results. As the ratio becomes larger, the load torque due to control decreases and the amplitude of the firing frequency component becomes more significant. In this case, the rectangular wave achieves beteer control.
