Abstract
A hydraulic control system for a work machine is disclosed. The hydraulic control system has first and second fluid actuators, first and second pumps, a combiner valve, and a controller. The first pump is configured to produce a first stream of pressurized fluid directed to the first fluid actuator. The second pump is configured to produce a second stream of pressurized fluid directed to the second fluid actuator. The combiner valve is movable toward a combining position at which the second stream of pressurized fluid is combined with the first stream of pressurized. The controller is configured to determine a flow rate for the first fluid actuator corresponding to a desired velocity, determine a flow capacity of the first pump, and move the combiner valve toward the combining position when the determined flow rate for the first fluid actuator is greater than the determined flow capacity of the first pump.
