A work machine control device includes a measurement-data acquisition unit that acquires measurement data of a three-dimensional measurement device that is mounted on a work machine including work equipment and measures a three-dimensional shape including a ridgeline of a work target on which the working equipment performs work, and a target calculation unit that calculates and outputs, based on the measurement data regarding the ridgeline of the work target, a distance from the work machine to the work target or an angle of repose of the work target.

Work machine control device, excavating machine control device, and work machine control method

A loading machine control device includes a measurement data acquisition unit acquiring measurement data of a measurement device mounted in a loading machine having working equipment, a target calculation unit calculating, based on the measurement data, a position of an upper end portion of a loading target to which an excavation object excavated by a bucket of the working equipment is loaded, a bucket calculation unit calculating position data of the bucket, an overlap determination unit determining whether the upper end portion of the loading target and the bucket that are in the measurement data overlap each other, and a working equipment control unit controlling the working equipment based on the measured position of the upper end portion of the loading target when it is determined that the upper end portion of the loading target and the bucket that are in the measurement data do not overlap each other.

Loading machine control device and loading machine control method

A control device for a loading machine includes a measurement data acquisition unit that acquires measurement data of a measurement device mounted on the loading machine that includes working equipment, a target calculation unit that extracts, from the measurement data, loading target data being measurement data on a loading target on which excavated material excavated by the working equipment is loaded and calculates, based on the loading target data, height data indicating a height of an upper end portion of the loading target and distance data indicating a distance from the loading machine to the loading target, and a working equipment control unit that controls the working equipment based on the height data and the distance data.

Control device for loading machine and control method for loading machine

A work vehicle periphery monitoring system includes: an alarm range storage unit that stores an alarm range, in which an alarm output is required when an object is present, in a detection range of an object detection device that detects an object present in a periphery of a work vehicle; a work mode determination unit that determines a work mode of the work vehicle; an alarm range changing unit that changes the alarm range in the detection range when it is determined that the work mode is a specific work mode; and an alarm control unit that causes an alarm device to output an alarm when an object is present in the alarm range.

Work vehicle periphery monitoring system and work vehicle periphery monitoring method

A work machine includes: a vehicle body front part to which a front wheel is attached; a vehicle body rear part which is coupled to the vehicle body front part through an articulated mechanism and to which a rear wheel is attached; a working equipment coupled to the vehicle body front part; a headlight supported by the vehicle body front part and arranged above the front wheel; and a three-dimensional measurement device arranged on an outer side of the headlight in a vehicle width direction that is in parallel with a rotation axis of the front wheel.

Work machine

A work vehicle includes a vehicle body, a working implement, a camera, and a display control unit. To the vehicle body, front tires are mounted. The working implement is movably coupled to the vehicle body and at least a part thereof is arranged anterior to the front tires. The camera is arranged at a front portion of the vehicle body and shoots an image of an anterior area outside the vehicle body as a shooting area. The display control unit causes a display device to display a shot image shot by the camera and a first guide image which indicates a first projection position obtained by projecting a first site of the working implement on a plane including ground-contacting surfaces of the front tires in a superimposed manner.

Work vehicle and display device

A periphery monitoring system includes an operation instruction output unit which outputs an operation instruction to a warning device provided in a work vehicle based on detection data of an object detection device detecting an object in a periphery of the work vehicle, an invalidating unit which invalidates the operation instruction based on an invalidating instruction output from a cancel operation device provided in a driving room of the work vehicle, and a validating unit which validates the invalidated operation instruction based on detection data of a boarding state detection device detecting a specific boarding state of a passenger in the driving room.

A surroundings monitoring system for a work vehicle includes a bending angle data acquirer acquiring bending angle data between a vehicle body front and rear portions, and a shot image data acquirer acquiring shot images respectively shot by multiple cameras, and a bird's eye image compositor performing image processing of a plurality of the shot image data to generate a bird's eye image, and a storage storing representative images of the work vehicle respectively belong to multiple bending angle ranges between the vehicle body front and rear portions, and a determiner determining, from the multiple bending angle ranges, a bending angle range to which the bending angle belongs, and a selector selecting, from a plurality of the representative images, a representative image that belongs to the determined bending angle range, and a display controller causing a display to simultaneously display the generated bird's eye image and the selected representative image.
