Abstract
A control system for a machine is disclosed. The control system has a ground engaging tool operable to remove material from a surface at a worksite. The control system also has a controller configured to generate a desired single-pass excavation contour prior to engagement of the ground engaging tool with the surface. The desired single-pass excavation contour has one or more predefined characteristics.
Claims17
A control system for a machine, comprising:
- a ground engaging tool operable to remove material from a surface at a worksite;
- and
- a controller configured to receive at least one input associated with a condition of the worksite and to generate a desired single-pass excavation contour prior to engagement of the ground engaging tool with the surface, the desired single-pass excavation contour based on a mathematically derived curve that is modified by a capacity of the machine and the condition of the worksite;
- the controller further configured to control positioning of the ground engaging tool to follow the single-pass excavation contour.
1 more element
A method of controlling a machine's work implement, comprising:
- providing a machine capacity input to an electronic controller;
- providing a worksite condition input to the electronic controller;
- generating a desired machine contour of a work surface based on a mathematical curve, the mathematical curve being modified by the machine capacity input and the worksite condition input;
- and
- controlling the position of the work implement to produce the desired excavation contour.
