System and method for controlling hydraulic fluid flow within a work vehicle

A system for controlling hydraulic fluid flow within a work vehicle, the system comprising:

• a first hydraulic load;
• a second hydraulic load in parallel with the first hydraulic load;
• a pump configured to supply hydraulic fluid to the first hydraulic load via a first fluid supply conduit and the second hydraulic load via a second fluid supply conduit;
• a first flow control valve fluidly coupled to the first fluid supply conduit upstream of the first hydraulic load;
• a second flow control valve fluidly coupled to the second fluid supply conduit upstream of the second hydraulic load;
• a load sense conduit fluidly coupled to the first and second fluid supply conduits downstream of the first and second flow control valves, respectively, the load sense conduit configured to receive a bleed flow of the hydraulic fluid from the first or second fluid supply conduit in which the hydraulic fluid is at a greater pressure such that an operation of the pump is controlled based on a pressure of the bleed flow within the load sense conduit;
• a load sense valve fluidly coupled to the load sense conduit, the load sense valve configured to adjust the pressure of the bleed flow within the load sense conduit;
• a first pressure sensor configured to capture data indicative of a first pressure of the hydraulic fluid within the first fluid supply conduit downstream of the first flow control valve;
• a second pressure sensor configured to capture data indicative of a second pressure of the hydraulic fluid within the second fluid supply conduit downstream of the second flow control valve;
• and
• a computing system communicatively coupled to the first and second pressure sensors, the computing system configured to:
• determine the first and second pressures based on the data captured by the first and second pressure sensors;
• and
• 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 first and second pressures.

A method for controlling hydraulic fluid flow within a work vehicle, the work vehicle including a pump configured to supply hydraulic fluid to a hydraulic load via a fluid supply conduit and a load sense conduit fluidly coupled to the fluid supply conduit downstream of a flow control valve, the load sense conduit configured to receive a bleed flow of the hydraulic fluid from the fluid supply conduit such that an operation of the pump is controlled based on a pressure of the bleed flow within the load sense conduit, the method comprising:

• determining, with a computing system, a flow rate of the hydraulic fluid within the fluid supply conduit downstream of the flow control valve based on received flow sensor data;
• determining, with the computing system, a pressure of the hydraulic fluid within the fluid supply conduit downstream of the flow control valve based on received pressure sensor data;
• and
• controlling, with the computing system, an operation of a load sense valve fluidly coupled to the load sense conduit in a manner that selectively adjusts the pressure of the bleed flow within the load sense conduit to adjust the operation of the pump based on the determined flow rate and the determined pressure.
