Abstract
An apparatus is provided with a dampening unit coupled to an engine. The apparatus further includes a control unit communicably coupled to the dampening unit. The control unit detects a gear shift in a transmission unit associated with the engine. The control unit further determines a dampening duration of the dampening unit at the detected gear shift. The dampening duration corresponds to a time taken for the dampening unit to absorb torsional vibrations of the engine at the detected gear shift. The control unit further compares the determined dampening duration at the detected gear shift with a preset dampening duration at a preset gear shift. The control unit further determines, based on the comparison, a torque control amount for the dampening unit to absorb the torsional vibrations of the engine. The control unit further controls the dampening unit based on the determined torque control amount.
