Abstract
An engine lubrication oil flow control system and control method for an engine in a hybrid electric vehicle powertrain is disclosed. An engine lubrication oil pump is powered by a lubrication oil pump motor. Provision is made to start the lubrication pump motor at the initiation of engine cranking upon a transition from an engine-off driving mode to an engine-on driving mode. An engine oil pressure signal is used to indicate engine filter maintenance is needed. The oil pump motor may be powered by a vehicle powertrain traction battery.
