Abstract
A system and method is provided for initiating starting of an engine in a hybrid electric vehicle (HEV) for a first time since a vehicle drive start request. Based on a predetermined fluid temperature and a powertrain fluid temperature from at least one of the powertrain elements in the HEV, it is determined whether energy from the engine is demanded. When the energy from the engine is demanded, the engine is started to provide energy for at least one of heating of a cabin compartment in the HEV and lubrication of a portion of powertrain elements in the HEV.
