Apparatus for controlling a power source of a hybrid vehicle, an operating method thereof, and a system having the same

A method of operating an apparatus for controlling a power source of a hybrid vehicle, the method comprising:

• predicting an inertial torque based on engine-related information;
• predicting a pressure torque based on the engine-related information;
• predicting engine torque fluctuations based on the engine-related information, the inertial torque, and the pressure torque;
• and
• outputting a reverse torque instruction to offset the engine torque fluctuations.

A system for controlling a power source of a hybrid vehicle, the system comprising:

• a vehicle information provider configured to provide vehicle-related information;
• an apparatus for controlling the power source of the hybrid vehicle;
• and
• a motor control unit (MCU) configured to control a motor based on a reverse torque instruction output from the apparatus for controlling the power source of the hybrid vehicle,
• wherein the apparatus for controlling the power source of the hybrid vehicle includes
• a storage configured to store one or more algorithms for predicting engine torque fluctuations and store one or more look-up tables (LUT), and
• a power source controller configured to
• predict an inertial torque and a pressure torque related to an engine based on engine-related information,
• predict engine torque fluctuations based on the engine-related information, the inertial torque, and the pressure torque, and
• output a reverse torque instruction to offset the engine torque fluctuations.
