摘要： A hydraulic control system for a work machine is disclosed. The hydraulic control system has a fluid actuator, a supply of pressurized fluid, and a control valve movable to selectively pass pressurized fluid to the fluid actuator. The hydraulic control system also has a sensor configured to sense the pressure of the pressurized fluid passed to the fluid actuator and a controller in communication with the control valve and the sensor. The controller is configured to receive an input indicative of a desired velocity of the fluid actuator and to determine a fluid flow rate corresponding to the desired velocity. The controller is also configured to determine a ratio of the sensed pressure to a stall pressure of the supply and to scale down the determined flow rate an amount based on the determined ratio. The controller is further configured to move the control valve an amount corresponding to the scaled down flow rate.

摘要： A hydraulic system has a source, a plurality of fluid actuators, and a controller. The controller is configured to receive an input indicative of which of the plurality of fluid actuators are a first and a second type of fluid actuator, to receive an input indicative of a desired flow rate for the plurality of fluid actuators, and to determine a current flow rate of the source. The controller is further configured to demand the desired flow rate for the first type of fluid actuator and to demand a scaled down desired flow rate for the second type of fluid actuator when a total desired flow rate exceeds the current flow rate of the source, and to demand a scaled down desired flow rate for all of the plurality of fluid actuators when the desired flow rate for the first type of fluid actuator exceeds the current flow rate of the source.

摘要： A hydraulic control system for a work machine is disclosed. The hydraulic control system has a first pump, a second pump, an operator control device, and a controller. The first and second pumps are configured to pressurize a fluid. The operator control device is movable through a range of motion from a neutral position to a maximum position to generate a corresponding control signal. The controller is in communication with the first pump, the second pump, and the operator control device. The controller is configured to receive the control signal, affect operation of the first pump in response to the control signal as the operator control device is moved throughout the range of motion, and affect operation of the second pump in response to the control signal only as the operator control device is moved through a portion of the range of motion.
