APPARATUS AND METHOD OF CONTROLLING HEATING OF HYBRID ELECTRIC VEHICLE

A method of controlling heating of a hybrid electric vehicle is provided. The method includes receiving a heating request from a driver; determining whether an entry condition of pre-FATC engine ON request (PFEOR) control is satisfied; checking whether the vehicle is capable of entering a HEV mode; determining whether the vehicle enters an idle mode for the PFEOR control; issuing a command for a target engine torque value and a target revolutions per minute for the idle mode to an engine control unit (ECU) from a hybrid control unit (HCU); and performing an engine idle speed control along with engine ON based on the command.
