System for controlling a hydraulic system
First Claim
1. A method of operating a hydraulic system, comprising:
- holding an implement configuration in an orientation;
sensing a first pressure within at least one chamber of at least one hydraulic actuator associated with the implement configuration when the implement configuration is in the orientation;
comparing a first signal indicative of the first sensed pressure with a first pressure value;
selecting a first functional relationship from among a plurality of stored functional relationships if the first signal is greater than the first pressure value;
selecting a second functional relationship from among the plurality of stored functional relationships if the first signal is less than the first pressure value; and
controlling the hydraulic actuator based on the selected functional relationship.

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.

12. A method of operating a hydraulic system, comprising:
-
moving an implement configuration through a motion; sensing a first pressure within at least one chamber of at least one hydraulic actuator associated with the implement configuration when the implement configuration moved through the motion; comparing a first signal indicative of the first sensed pressure with a first pressure value; selecting a first functional relationship from among a plurality of stored functional relationships if the first signal is greater than the first pressure value; selecting a second functional relationship from among the plurality of stored functional relationships if the first signal is less than the first pressure value; and controlling the hydraulic actuator based on the selected functional relationship. - View Dependent Claims (13, 14, 15, 16, 17)

18. A machine having a hydraulic system, comprising:
-
an implement configuration including a tool and a linkage system; a hydraulic actuator that affects movement of a component of the implement configuration, the hydraulic actuator including a first chamber and a second chamber; a sensor that senses pressure within at least one chamber while the implement configuration is controlled in a first manner; and a controller in communication with the sensor and configured to compare a signal indicative of the sensed pressure with a first pressure value, modify a stored functional relationship as a function of the signal, and control the hydraulic actuator in a second manner based upon the modified functional relationship. - View Dependent Claims (19, 20)
