HYBRID VEHICLE AND A METHOD OF CONTROLLING TORQUE FLUCTUATIONS THEREOF

A hybrid vehicle and a method for controlling torque fluctuations. The hybrid vehicle includes a controller configured to determine engine torque fluctuations in a transient state in which an operating point of the engine changes based on an inertial torque generated by rotational inertia during the operation of the engine and a pressure torque caused by pressure generated during combustion of fuel in the engine. The controller is configured to apply a counter torque command to the motor to offset the engine torque fluctuations.
