  • System for controlling a hydraulic system
    Patent number: 8095281
    Abstract: A method of operating a hydraulic system is disclosed. The method includes holding an implement configuration in an orientation. The method also includes sensing a pressure within a chamber of a hydraulic actuator associated with the implement configuration when the implement configuration is in the orientation and comparing a first signal indicative of the first sensed pressure with a first pressure value. The method further includes selecting a first functional relationship from among a plurality of stored functional relationships if the first signal is greater than the first pressure value and selecting a second functional relationship from among the plurality of stored functional relationships if the first signal is less than the first pressure value. The method includes controlling the hydraulic actuator based on the selected functional relationship.
