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.
Claims12
A method for controlling engine power during charge depleting (CD) mode heating of a plug-in hybrid electric vehicle (PHEV), wherein the engine power is controlled according to an amount of heat of an engine required for heating 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.
A method for controlling engine power during charge depleting (CD) mode heating of a plug-in hybrid electric vehicle (PHEV), the method comprising:
- a CD mode determination step of determining whether or not the PHEV is driven in a CD mode;
- an air-conditioning blower stage determination step of determining a stage of an air-conditioning blower according to a level of the air-conditioning blower;
- an engine power map selection step of selecting an engine power map according to the stage of the air-conditioning blower determined in the air-conditioning blower stage determination step;
- an engine power setting step of setting optimal engine power by monitoring an outdoor air temperature and a coolant temperature according to the engine power map for each stage of the air-conditioning blower selected in the engine power map selection step;
- and
- an engine turning-on step of operating an engine by the engine power set in the engine power setting step.
