A system includes a processor and a display. The processor acquires shape data indicative of a shape of the surroundings in a traveling direction of a work machine. The processor generates a guide line. The guide line is disposed spaced from the work machine. The guide line indicates the shape of the surroundings in the traveling direction of the work machine. The processor synthesizes a surrounding image and the guide line and generates an image including the surroundings image and the guide line. The display displays the image including the surroundings image and the guide line based on a signal from the processor. The system may further include the work machine, a camera that captures the surrounding image, and a sensor that measures the shape of surroundings.

A mobile work machine includes a frame, a material loading system having a material receiving area configured to receive material and an actuator configured to control the material loading system to move the material receiving area relative to the frame, and a control system configured to receive an indication of a detected object, determine a location of the object relative to the material loading system, and generate a control signal that controls the mobile work machine based on the determined location.

A system for controlling the lateral traverse position of a front three-point hitch mounted side-shifting implement and a rear three-point hitch mounted side-shifting implement on a mobile machinery such as an agricultural tractor with an controllable automated steering device, while simultaneously controlling the position of the tractor relative to the positions of each of the two side-shifting implements. The system uses a controller to control the positions of the side-shifting-implements using information received from a position monitoring system communication with roving receivers mounted on the side-shifting-implements. The controller also controls the position of the mobile machinery using local relationship sensors mounted on the side-shifting-implement's position and on the mobile machinery's position. The relationship sensors allow the controller to use two roving data receivers instead of three roving data receivers to control both the position of the side shifting implements and the position of the mobile machinery.

A loading vehicle detects the position of a receiving vehicle relative to the loading vehicle and determines whether the receiving vehicle is to be repositioned. If so, it sends a repositioning message to the receiving vehicle and receives acknowledgement that the loading vehicle has remote control of the positioning mechanisms in the receiving vehicle. A loading vehicle operator input is detected and a position control signal is sent to the receiving vehicle to reposition it relative to the loading vehicle.

A purpose of the present invention is to provide a remote operation assistance system used for assisting an operator OP in remotely operating a work machine. In order to achieve this purpose, the remote operation assistance system of the present invention includes: a distance acquisition unit 201 that obtains information on a distance from the operator OP to a moving body M; an attribute acquisition unit 202 that obtains an attribute to which the moving body M belongs; an interference determination unit 203 that determines a level of likelihood of interference occurring with the remote operation, based on the distance obtained by the distance acquisition unit 201 and the attribute obtained by the attribute acquisition unit 202; and an assistance control unit 204 that performs control to assist in the remote operation according to a result of the determination by the interference determination unit 203.

A hydraulic excavator for performing cooperative work with another hydraulic excavator or a worker includes: a driving device that makes the hydraulic excavator operate; a cooperative function device that shares information about the hydraulic excavator with an inside and an outside of the hydraulic excavator; and a controller that controls the driving device that makes the hydraulic excavator operate, the controller, when there is an abnormality in the cooperative function device, controlling the driving device so as to limit operation of the hydraulic excavator, and when the hydraulic excavator is performing the cooperative work, controlling the driving device so as to make a degree of limitation on the operation of the hydraulic excavator stronger than when the hydraulic excavator is not performing the cooperative work. It is thereby possible to suppress an unnecessary decrease in work efficiency by suppressing an excessive operation limitation on the hydraulic excavator.

A working vehicle is capable of autonomously traveling on a target traveling route and appropriately performing illumination during autonomous traveling to enable an operator to reliably confirm the presence of obstacles or the like on the target traveling route. The working vehicle includes a traveling body to autonomously travel on the target traveling route, illumination lamps located on the traveling body to respectively illuminate different directions, and a controller to change a control relating to a way of turning on the illumination lamps during the autonomously traveling.

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.

A system includes a region data module and a planning module. The region data module acquires excavation region data and embankment region data. The excavation region data indicates positions of a plurality of excavation regions at a work site. The embankment region data indicates positions of a plurality of embankment regions at the work site. The planning module determines, as a construction plan, a construction sequence and a target travel path including a combination of a plurality of travel paths connecting the excavation regions and the embankment regions while taking into account a change in a topography at the work site.

A method for automatically controlling an operation of a work vehicle during the performance of an earthmoving operation may include receiving an input associated with initiating an automated dumping operation to allow a load of worksite materials contained by an implement of a lift assembly of the work vehicle to be released onto a dump pile. The method may further include determining a current vertical height of the dump pile based on data from at least one sensor and determining a dumping height of the implement for performing the dumping operation based on the current vertical height. Additionally, the method may include controlling an operation of the lift assembly to move the implement to the dumping height and then to pivot the implement from a load-carrying position to a load-dumping position to release the load of worksite materials onto the dump pile from the dumping height.
