Excavation system having adaptive dig control

摘要

An excavation system is disclosed for a machine having a work tool. The excavation system may have a speed sensor to detect a travel speed of the machine and a load sensor to detect loading of the work tool. The excavation system may also have a controller configured to detect engagement of the work tool with a material pile based on at least one of the first signal and the second signal. The controller may also be configured to select at least one tilt control parameter value for the work tool and operate the work tool based on the selected tilt control parameter value to load the work tool with an amount of material. The controller may be configured to determine whether the amount of material exceeds a target amount and to cause the machine to withdraw from the material pile when the amount exceeds the target amount.

1. An excavation system for a machine having a work tool, comprising:
a speed sensor configured to generate a first signal indicative of a travel speed of the machine; at least one load sensor configured to generate a second signal indicative of loading of the work tool; a controller in communication with the speed sensor and the at least one load sensor, the controller being configured to:
detect engagement of the work tool with a material pile based on at least one of the first signal and the second signal;select at least one tilt control parameter value for the work tool;operate the work tool based on the selected tilt control parameter value to load the work tool with an amount of material;determine whether the amount of material exceeds a target amount;cause the machine to withdraw from the material pile when the amount exceeds the target amount; andwherein the controller is further configured to position a wheel of the machine by raising the work tool to a target height above a ground surface.
