Abstract: An acceleration detection device includes a first acceleration acquisition unit configured to acquire a first acceleration from a mechanical acceleration sensor a second acceleration acquisition unit configured to acquire a second acceleration from a non-mechanical acceleration sensor and a correction value calculation unit configured to calculate a correction value for correcting the first acceleration using the second acceleration.

Abstract: A controller calculates a first bearing indicative of the bearing of a work machine based on first positional data and second positional data. The controller calculates the position of the work machine. The controller calculates a second bearing indicative of the bearing of the work machine based on a change in the position of the work machine in a predetermined zone when a determination condition, including a travel condition indicating that the work machine is traveling in a straight line, is satisfied within the predetermined zone. The controller calculates a correction value of the bearing of the work machine based on the difference between the first bearing and the second bearing in the predetermined zone. The controller corrects the first bearing based on the correction value.

Abstract: An aspect of the present disclosure provides an acceleration detection device, including: a first acceleration acquisition unit configured to acquire a first acceleration from a mechanical acceleration sensor; a second acceleration acquisition unit configured to acquire a second acceleration from a non-mechanical acceleration sensor; and a correction value calculation unit configured to calculate a correction value for correcting the first acceleration using the second acceleration.

Abstract: A controller is configured to determine a target excavation depth of a first pass based on a position of an excavation end, a target soil amount, and an excavation distance. The controller is configured to move a work implement to the target excavation depth of the first pass to execute an excavation of the first pass. The controller is configured to acquire an actual soil amount excavated in the first pass. The controller is configured to modify the target soil amount based on the actual soil amount. The controller is configured to determine the target excavation depth of a second pass based on the modified target soil amount. The controller is configured to move the work implement to the target excavation depth of the second pass to execute the excavation of the second pass.

Abstract: A work machine control system includes: an acquisition unit configured to acquire a plurality of pieces of current topographical data indicating a current topography of a work site where a work machine performs work; and a combining unit configured to generate combined current topographical data of the work site in accordance with a predetermined rule based on the plurality of pieces of current topographical data acquired in the acquisition unit.
