Experimental verification of engine vibration suppression control using hybrid electric vehicle simulator

This study aims, for hybrid electric vehicle, to reduce the torque ripple caused by fuel combustion in the combustion engine and reaction torque from road surface. The assist motor in HEV is driven to suppress the torque ripple under the torque ripple suppression control proposed by Fujita. However, effectiveness of this proposed method is not inspected using the actual equipment. This paper, effectiveness of this proposed method is inspected by using HEV simulator. As a result, the torque ripple is reduced by 33%.
