A method for grouping hydraulic functions associated with an agricultural implement includes accessing parameter data associated with hydraulic fluid used to drive a plurality of hydraulic functions of the implement, the hydraulic fluid being supplied from one of at least two pumps. The method also includes determining delivery pump pressures for the pumps for each of a plurality of different pump/function combinations based at least in part on the hydraulic parameter data and determining a power parameter requirement for the pumps for each of the different pump/function combinations based at least in part on the delivery pump pressures. In addition, the method includes selecting a desired pump/function combination based at least in part on the power parameter requirement, and controlling an operation of a plurality of switching valves such that the hydraulic fluid is supplied for driving the hydraulic functions in accordance with the desired pump/function combination.

Systems and methods for grouping hydraulic functions for an agricultural implement

A system for controlling pump operation within a work vehicle includes a pump configured to discharge hydraulic fluid into a fluid supply conduit for delivery to first and second hydraulic loads of an associated agricultural implement. Furthermore, the agricultural vehicle includes a pump compensator assembly configured to control the operation of the pump. The pump compensator assembly, in turn, includes a pump regulation actuator and a flow compensator valve. Moreover, the pump compensator assembly includes an electronically controlled pressure compensator valve configured to at least partially control the flow of the hydraulic fluid to the pump regulation actuator for use in controlling the operation of the pump.

System and method for controlling hydraulic pump operation within a work vehicle

A system for controlling hydraulic fluid flow within a work vehicle includes a load sense valve configured to adjust the pressure of a bleed flow within a load sense conduit. Moreover, the system includes a computing system configured to determine the pressure of the hydraulic fluid within the fluid supply conduit downstream of the flow control valve based on the data captured by a pressure sensor. Furthermore, the computing device is configured to control an operation of the load sense valve to selectively adjust the pressure of the bleed flow within the load sense conduit based on the determined pressure.
