Control Of Variable Displacement Vane Pump Used As Scavenge Pump

A system includes a first scavenge oil pump that draws oil from a first draw location within a vehicle according to a first variable displacement associated with the first scavenge oil pump. The first variable displacement is based on a first modified scavenge ratio assigned to the first scavenge oi...

Beschreibung
Zusammenfassung:	A system includes a first scavenge oil pump that draws oil from a first draw location within a vehicle according to a first variable displacement associated with the first scavenge oil pump. The first variable displacement is based on a first modified scavenge ratio assigned to the first scavenge oil pump. An oil pump control module determines a first scavenge ratio, determines a first scavenge ratio multiplier based on at least one of vehicle acceleration and vehicle orientation, and applies the first scavenge ratio multiplier to the first scavenge ratio to generate the first modified scavenge ratio.
