A method and system of controlling an engine for vehicle interior heating is provided. The method includes performing a first engine control when the engine is not in an engine-on state for vehicle driving, to perform heating control for interior heating at a predetermined range of a reference coolant temperature. Additionally, the method includes performing a second engine control when the engine is in an engine-on state for vehicle driving, to prolong an engine-on time for vehicle driving by setting a minimum value of the range of the reference coolant temperature to a lower value and setting a maximum value of the range of the reference coolant temperature to a higher value and to determine a point of time of engine-off operation based on a real-time lock up time and an average lock up time of an engine clutch for vehicle driving.

System and method of controlling engine for vehicle interior heating

The present disclosure provides an apparatus and a method for controlling an engine of a hybrid vehicle. The apparatus includes an environment information collection unit configured to collect traveling environment information of the hybrid vehicle, a determination unit configured to compare the traveling environment information with reference information and determine whether the traveling environment information meets a preset condition, a setting unit configured to set a reference coolant temperature based on the traveling environment information and change the reference coolant temperature based on the traveling environment information when the traveling environment information meets the preset condition, and an engine control unit configured to prevent the engine from operating heating and air-conditioning control of the hybrid vehicle when the traveling environment information meets the preset condition and a coolant temperature is lower than the reference coolant temperature changed by the setting unit.
