1. An apparatus, comprising:
a dampening unit coupled to an engine; and
a control unit communicably coupled to the dampening unit, wherein the control unit is configured to:
detect a gear shift in a transmission unit associated with the engine,
determine a dampening duration of the dampening unit at the detected gear shift, wherein the dampening duration corresponds to a time taken for the dampening unit to absorb torsional vibrations of the engine at the detected gear shift,
compare the determined dampening duration at the detected gear shift with a preset dampening duration at a preset gear shift,
determine, based on the comparison, a torque control amount for the dampening unit to absorb the torsional vibrations of the engine, and
control the dampening unit based on the determined torque control amount.
