Abstract
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.
