Abstract
An engine control method for heating of a hybrid electric vehicle, includes collecting information for air conditioning control by a sensor during an operation of a heating, ventilation, and air conditioning (HVAC) device in the hybrid electric vehicle in which forced engine driving for heating is performed, determining whether a condition that requires pre-engine driving as driving in a separate mode from forced engine driving is satisfied based on the collected information, upon determining that the condition that requires the pre-engine driving is required is satisfied, determining whether a condition for allowing the pre-engine driving is satisfied based on engine efficiency and hybrid system efficiency information, and upon determining that the condition for allowing the pre-engine driving is satisfied, performing the pre-engine driving for driving an engine to manage engine coolant temperature.
