Abstract: In a method for controlling engine power during charge depleting (CD) mode heating of a plug-in hybrid electric vehicle (PHEV), the engine power is controlled according to an amount of heat of an engine required for heating determined using a level of an air-conditioning blower at a point in time at which an operation of the engine starts, an outdoor air temperature, and a coolant temperature, if a full automatic temperature controller (FATC) operates the engine for heating when the vehicle is driven in a CD mode.

Abstract: A control method capable of variably applying an existing engine-on line includes: a prediction degree calculation unit to predict a degree to which a temperature of a coolant at a current point after the engine is turned off reaches a target temperature by a request of full automatic temperature control (FATC); a factor determination unit to set reference ranges divided based on an extent that the temperature is close to the target temperature, and to determine a factor value for each reference range so that a predetermined existing engine-on line or a predetermined existing engine-off line is varied by required power; and an engine on/off line determination unit configured to determine a corrected engine-on line or a corrected engine-off line by calculating the existing engine-on line or the existing engine-off line and the factor value in the reference range in which a calculation value is positioned.
