Apparatus for controlling engine idling of hybrid electric vehicle

An apparatus for controlling engine idling of a hybrid electric vehicle, the hybrid electric vehicle including an engine, a driving motor, and an electric motor for starting the engine, the apparatus comprising:

• an engine target speed determination part configured to determine an engine target speed when an engine idle speed control is requested;
• an engine target torque determination part configured to determine an engine target torque when the engine idle speed control is requested;
• a speed control part configured to determine a control torque for maintaining an engine speed at a predetermined speed based on a difference value between the engine target speed and an engine actual speed;
• a power split part configured to determine an output torque of the electric motor and an engine compensation torque of the engine based the control torque;
• and
• a final engine torque determination part configured to sum the engine compensation torque and the engine target torque to determine a final engine torque.
