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.

Abstract:
A total power demand including a wheel power demand may be observed. The wheel power demand may be modified to determine a modified total power demand including a modified wheel power demand if the total power demand falls within a target range of power values defined by upper and lower threshold power values such that the modified total power demand is generally equal to the lower threshold power value.
