Abstract
Official abstract text for this publication.
A system for lubricating transmission components with hydraulic fluid includes a pump and a motor coupled to the pump. The pump has an inlet port that receives hydraulic fluid and an outlet port from which hydraulic fluid is pumped to the transmission components. A pump pressure is regulated by adjusting a motor torque of the motor, and the motor torque is set by commands based on a look-up table or a formula.
