Abstract
A posture detection sensor detects a posture of a work implement. A controller identifies an unloading point and a passing point on a route through which a bucket passes during revolution of a revolving body, based on a detection result of the posture detection sensor, sets a position shifted from the passing point to a side opposite to the unloading point as a corrected passing point, and performs control such that the bucket passes through the corrected passing point during the revolution.
Claims7
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 posture detection sensor configured to detect a posture of the work implement;
- and
- a controller configured to:
- identify an unloading point and a passing point on a route through which the work tool passes during revolution of the revolving body, based on a result of the detection by the posture detection sensor;
- set, as a corrected passing point, a position shifted from the passing point to a side opposite to the unloading point;
- and
- perform control such that the work tool passes through the corrected passing point during the revolution.
A control method for a work machine, the work machine comprising:
- a revolving body configured to revolve;
- and
- a work implement attached to the revolving body and having a work tool, the control method comprising:
- identifying an unloading point and a passing point on a route through which the work tool passes during revolution of the revolving body, based on a detection result of a posture of the work implement;
- setting, as a corrected passing point, a position shifted from the passing point to a side opposite to the unloading point in a top view, and
- performing control such that the work tool passes through the corrected passing point during the revolution.
