Abstract
A system and method is provided for controlling operation of an electric oil pump in a hybrid electric vehicle (HEV). The HEV includes an engine and a transaxle including an electric motor coupled to a traction battery. A commanded speed for the electric oil pump is determined and whether the engine in the HEV is in an off state is determined. When the engine is in the off state, the electric oil pump is controlled to operate at the commanded speed.
