SYSTEMS AND METHODS FOR CONTROL OF EXCAVATORS AND OTHER POWER MACHINES
A power machine can include operator input devices and a control system configured to command movement of actuators based on operator inputs received from the operator input devices. Movement of one or more of the actuators can be commanded based on input at one or more of the operator input devices and a response curve selected from a plurality of different response curves. Movement of one or more of the actuators can be based on a selected control mode for the power machine that corresponds to a selected control-function mapping of the operator input devices to the one or more actuators. A lift arm can be variously controlled to execute automatic or other operations. An excavator can be operated in a sustained-speed travel mode.
Excavator that controls toe angle of bucket
An excavator includes a lower traveling body; an upper turning body mounted on the lower traveling body; an attachment attached to the upper turning body; an attitude detecting device configured to detect an attitude of the attachment including a bucket; and a control device configured to control a toe angle of a toe of the bucket with respect to an excavation ground, based on a transition of the attitude of the attachment, information relating to a present shape of the excavation ground, and an operation content of an operation device relating to the attachment.

WORK MACHINE CONTROL SYSTEM, WORK MACHINE, AND WORK MACHINE CONTROL METHOD
A distance calculation unit calculates a bucket distance that is a distance between a point on a bucket and a target design surface representing a target shape of an excavation target. An intervention control unit calculates an intervention control amount to suppress a speed of work equipment such that the bucket does not intrude on the target design surface based on the bucket distance. An attachment control unit calculates an attachment control amount to rotate the bucket around an attachment axis such that an edge of the bucket and the target design surface approach each other in a parallel state. An attachment limiting unit limits rotation of the bucket around the attachment axis such that the bucket distance is not increased by a movement of the work equipment based on the intervention control amount and the attachment control amount.

System and method for performing an earthmoving operation
A system for performing an earthmoving operation may include a work vehicle having an articulable implement and a soil composition sensor supported on the work vehicle. The soil composition sensor may generate data indicative of a soil composition below a surface of a worksite. The system may additionally include a computing system communicatively coupled to the soil composition sensor and the work vehicle. The computing system may receive an input associated with a target profile of the worksite. The computing system may further receive the data indicative of the soil composition of the worksite. Additionally, the computing system may generate an earthmoving prescription map based at least in part on the target profile of the worksite and the soil composition of the worksite, where the earthmoving prescription map indicates soil composition layers between the surface of the worksite and the target profile of the worksite.

WORK MACHINE
In a work machine, a load information output part outputs a load calculated by a load calculation part as load information before a piston member shifting toward a stroke end reaches a specific position, and a load storage part stores the load calculated by the load calculation part as a specific load when the piston member shifting toward the stroke end reaches the specific position. The load information output part further outputs the specific load as the load information after the piston member shifting toward the stroke end enters a specific region.
