    摘要: 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.

    摘要: A system and method for controlling the speed of an engine includes determining a desired engine power output and engine speed, and determining whether the desired engine speed is within one of a number of predetermined engine speed ranges. It is then determined whether a noise-vibration level for the vehicle is within a target range when it is determined that the desired engine speed is within one of the predetermined engine speed ranges. The noise-vibration level is a function of at least one of a corresponding vibration level for one or more vehicle mechanical systems, and a noise level for the passenger compartment for the engine operating at the desired engine speed. The engine is then controlled at the desired engine speed when the determined noise-vibration level is within a target range, and it is determined that the desired engine speed is within one of the predetermined engine speed ranges.
