ADAPTIVE WORK CYCLE CONTROL SYSTEM
First Claim
1. A control system for a machine, comprising:
- a work tool;
an operator input device configured to receive input indicative of a desired movement of the work tool;
at least one actuator configured to move the work tool;
at least one sensor associated with at least one of the work tool and the at least one actuator; and
a controller in communication with the operator input device, the at least one actuator, and the at least one sensor, the controller being configured to;
make a classification of a current operation of the machine as one of a plurality of known operations based on a signal from at least one of the operator input device and the at least one sensor; and
adjust an operational parameter of the at least one actuator based on the classification.

Abstract
A control system is disclosed for use with an excavation machine. The control system may have a work tool, an operator input device to receive input indicative of a desired movement of the work tool, at least one actuator, and at least one sensor associated with at least one of the work tool and the at least one actuator. The control system may also have a controller in communication with the operator input, the at least one actuator, and the at least one sensor. The controller may be configured to make a classification of a current operation of the machine as one of a plurality of known operations based on a signal from at least one of the operator input device and the at least one sensor. The controller may be further configured to adjust an operational parameter of the at least one actuator based on the classification.

11. A method of controlling a work tool, comprising:
-
receiving operator input indicative of a desired work tool movement; controlling an actuator to move the work tool based on the input; generating a signal indicative of an actual work tool movement; making a classification of a current operation of the work tool as one of a plurality of known operations based on at least one of the operator input and the signal; and adjusting an operational parameter of the actuator based on the classification. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A method of controlling a work tool, comprising:
-
receiving operator input indicative of a desired work tool movement; controlling a hydraulic cylinder to raise or lower the work tool based on the input; generating a signal indicative of an actual work tool movement; making a classification of a current operation of the work tool as a digging operation based on at least one of a pattern of the operator input and the signal; and increasing an acceleration limit of the hydraulic cylinder to about three times a base value corresponding to the classification.
