Abstract
A work implement posture sensor detects a posture of a work implement. A controller identifies a passing point through which a bucket passes during revolution of a revolving body, based on a result of the detection by the work implement posture sensor, calculates a corrected passing point by adding a vertical offset, derived from shape data of the bucket, to the height position of the passing point, and controls the bucket so as to pass through the corrected passing point during the revolution.
Claims6
An automatic control system for a work machine, comprising:
- a revolving body configured to revolve;
- a work implement attached to the revolving body and having a work tool;
- a work implement posture sensor configured to detect a posture of the work implement;
- and
- a controller configured to:
- identify a passing point through which the work tool passes during revolution of the revolving body, based on a result of the detection by the work implement posture sensor;
- calculate a corrected passing point by adding a vertical offset, derived from shape data of the work tool, to the height position of the passing point;
- and
- perform control such that the work tool passes through the corrected passing point during the revolution.
