Abstract: A system controls a plurality of work machines including a first work machine and a second work machine. The system includes a communication device configured to wirelessly communicate with the plurality of work machines, and a controller. The controller acquires area data indicative of a position of a work area. The controller determines a first work path to be dug by the first work machine, the first work path extending in a predetermined work direction in the work area. The controller determines a second work path to be dug by the second work machine, the second work path extending in the work direction in the work area and disposed at an interval from the first work path in a lateral direction intersecting the work direction. The controller determines a next first work path and a next second work path so that the interval is decreased.

Abstract: A first assessment is made as to whether conveying of earth and sand to a first unloading position by a conveyance vehicle has been completed. The conveyance vehicle is controlled to exit the first operating region when the conveying of the earth and sand to the first unloading position has been completed. A second assessment is made as to whether the conveyance vehicle has exited the first operating region. An entry of the conveyance vehicle into the first operating region is prohibited when the conveyance vehicle has exited the first operating region. An entry of a bulldozer into the first operating region is permitted after the entry of the conveyance vehicle into the first operating region has been prohibited.

Abstract: A first process acquires a boundary position between a work area and a dumping area. A second process acquires a current position of a work machine. A third process controls the work machine so as to form a berm that acts as a wheel stop by raising a work implement from a position, the position being away from the boundary position toward the work area by a predetermined distance, when the work machine is traveling from the work area toward the dumping area.

Abstract: A controller acquires current position data indicative of a current position of a work machine. The controller acquires an inclination angle of an actual topography to be dug. The controller acquires a maximum climbing angle when the work machine travels in reverse. The controller determines a digging angle with respect to the actual topography based on the inclination angle and the maximum climbing angle. The controller determines a target digging trajectory based on the digging angle. The controller controls a work implement according to the target digging trajectory.

Abstract: A first work machine includes a work implement. A method of controlling the first work machine includes acquiring a traveling state of the first work machine that is performing work with the work implement while traveling on a first work path, determining whether the first work machine is deviating from the first work path based on the traveling state, and stopping travel of the first work machine upon determining that the first work machine is deviating from the first work path.

Abstract: A system includes a plurality of work machines, a communication device, an operating device, and a controller. The plurality of work machines are able to operate automatically. The plurality of work machines include a first work machine and a second work machine. The communication device communicates wirelessly with the plurality of work machines. The operating device transmits an operation signal to the plurality of work machines via the communication device. The operating device is able to operate the plurality of work machines remotely and individually. The controller disables the operation of the operating device on the first work machine when the first work machine and the second work machine are operating automatically.

Abstract: A controller acquires a target soil amount in one work path with respect to an actual topography. The controller determines a target profile in the one work path based on the target soil amount. The controller performs work in the one work path by operating a work implement according to the target profile. The controller acquires a maximum traction force of the work machine during the one work path. The controller determines whether the maximum traction force is smaller than a reference traction force. The controller increases the target soil amount in a next work path when the maximum traction force is smaller than the reference traction force. The controller determines the target profile in the next work path based on the increased target soil amount.
