Abstract
An intelligent clutch lubrication system includes a first dynamically-lubricated clutch pack, a supply pump, a first lubricant control (LC) valve, and a lubricant flow circuit having a clutch lubrication loop in which the first clutch pack is positioned. When active, the supply pump urges lubricant flow about the lubricant flow circuit and through the clutch lubrication loop. The first LC valve is positioned in the clutch lubrication loop at a location upstream of the first clutch pack, while a controller architecture is operably coupled to the first LC valve. the controller architecture is configured to control the first LC valve to temporarily boost lubricant flow to the first DL clutch pack when moving into an engaged position during operation of the intelligent clutch lubrication system.
