摘要： A hydraulic system is disclosed. The hydraulic system may have a pump, a lift actuator, a lift valve arrangement, a tilt actuator, a tilt valve arrangement, and a tilt angle sensor configured to generate a first signal. The hydraulic system may further have at least one operator interface device movable to generate a second signal indicative of a desired lift velocity and a third signal indicative of desired tilt velocity, and a controller. The controller may be configured to command the lift valve arrangement to meter pressurized fluid based on the second signal, command the tilt valve arrangement to meter pressurized fluid based on the third signal and, when the first signal indicates that the actual tilt angle has entered a specified range of tilt angles during lifting, command the tilt valve arrangement to meter pressurized fluid based on the second signal as the actual tilt angle remains within the specified range.

摘要： A method of allocating hydraulic fluid between two or more actuators in a machine processes a first command intended to provide a first requested fluid flow to a steering actuator for steering the machine, and a second command intended to provide a second requested fluid flow to a non-steeling actuator, such as a lift or tilt actuator. The system modifies the first and second commands to produce modified first and second commands corresponding to modified first and second fluid flows, such that the sum of the adjusted first and second fluid flows is less than or equal to a currently available flow and the modified first fluid flow meets or exceeds the lesser of the first requested fluid flow and a threshold curve that is a function of a machine variable such as engine speed or other variable or parameter.

摘要： A method of allocating hydraulic fluid between actuators in a machine accepts a first command to provide a first requested fluid flow to a first actuator, wherein the first actuator is a bounded actuator such as a steering actuator, and a second command to provide a second requested fluid flow to a second actuator. The system adjusts the first and second commands to produce adjusted first and second commands corresponding to adjusted first and second fluid flows, such that the sum of the adjusted first and second fluid flows is less than or equal to a maximum available flow and the adjusted first fluid flow meets or exceeds the lesser of the first requested fluid flow and a threshold curve that is a function of engine speed or other variable.
