  • Flow control for electro-hydraulic systems
    Patent number: 6498973
    Abstract: In a work vehicle that has several hydraulic actuators a system and method for controlling and scaling flow between the actuators includes an electronic controller that is connected to several hand controls that provide a proportional signal indicating how far the operator has moved the hand controls. The controller reads the hand controls and proportionally scales the total available flow to make sure the operator does not demand too much fluid from the hydraulic pump.
