WIPO Patent Application WO/2024/075639

A1

In the present invention, a control device for a work machine sets a release start position and a release stop position lined up in a direction having a component of the longitudinal direction of a vessel, on the basis of information regarding the position of the vessel acquired by a vessel position acquisition device at a position where an excavation action is completed, the release start position being a position where an excavated-material-releasing operation carried out above the vessel is started, and the release stop position being a position where the releasing operation is stopped. On the basis of the orientations of a work device and a turning body detected by an orientation detection device, the control device controls the operations of the work device and/or the turning body, thereby causing a control point of the work device to move from the release start position to the release stop position and controls the operation of the work device so that the bucket ground angle reaches a preset release stop angle until the control point of the work device moves from the release start position to the release stop position.
