ABSTRACT:
A method of flowing hydraulic fluid in a work machine is disclosed. The method includes generating a control signal from an input mechanism and generating a property signal indicative of a viscosity of the hydraulic fluid. The control signal and the property signal are received at a control module. The method also includes determining a desired volume flow rate for the control signal and determining a valve control signal required to achieve the desired volume flow rate for the control signal. The valve control signal is based upon the property signal. The valve control signal is output to a proportional valve to provide the desired volume flow rate through the valve for the command signal.
