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.

System and method for calibrating bearing of work machine

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.

System and method for controlling work machine

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.
