摘要： A control system for a work vehicle, which includes a vehicle body and work equipment that is changeable in height and pitch with respect to the vehicle body, includes a controller. The controller determines a switching point by referring to target displacement data indicating a target displacement of the height of the work equipment according to a movement amount of the work vehicle from a work start position. The controller determines whether or not the work vehicle has reached the switching point based on the movement amount of the work vehicle from the work start position. The controller outputs a command to change the pitch of the work equipment upon determining that the work vehicle has reached the switching point.

摘要： A work machine comprises a body, a ripper apparatus that is disposed behind the body, and an imaging device that is mounted to the body and images the ripper apparatus. The ripper apparatus includes a shank, a ripping tip that is attached to an end of the shank, a beam that supports the shank, and a ripper arm that interconnects the body and the beam. The imaging device images the ripper apparatus sideways and captures an image in a range including at least a portion of the shank, at least a portion of the beam, and at least a portion of the ripper arm.

摘要： A system controls a work machine including a work implement. The system includes a sensor and a controller. The controller acquires current position data of the work machine, acquires actual topography data, acquire default target displacement data that defines a target displacement according to a movement amount of the work machine, acquires a work interval indicative of a distance between a previous start position of work by the work machine and a current start position behind the previous start position, generates modified data with the default target displacement data modified according to the work interval, refers to the modified data to determine the target displacement according to the movement amount of the work machine from the current start position, determines topography data with the actual topography data vertically displaced downward by the target displacement as a target profile, and moves the work implement according to the target profile.

摘要： An amount of information of data of a captured image displayed on a display unit is increased. A display control unit sets a plurality of divided display sections for a display unit. The display control unit sets a first camera group and a second camera group including one or more of a plurality of cameras. The first camera group captures an image of a work performed with a blade. The second camera group captures an image of a work performed with a ripper. The display control unit displays data of captured images output from cameras included in one of the first and second camera groups in a corresponding plurality of divided display sections.
