A hydraulic excavator includes a controller having an actuator control section that executes machine control of operating a work implement in accordance with a predetermined condition in a case in which a work implement is positioned in a deceleration area, and that does not execute machine control in a case in which the work implement is positioned in a non-deceleration area. The controller further includes an operation deciding section that decides operation of the work implement on the basis of an operation amount of an operation device, and a display control section that displays, on a display device, a positional relationship among the work implement, a target surface and a boundary line between the deceleration area and the non-deceleration area. The actuator control section executes machine control while changing the position of the boundary line depending on a result of the decision by the operation deciding section, and the display control section changes the display position of the boundary line on the display device, depending on the result of the decision by the operation deciding section.

A working machine includes a body, a ground engaging propulsion structure supporting the body, a working arm, a control system, and a collision avoidance system. The collision avoidance system has a camera configured to monitor an area in its field of view and to generate an output signal to the control system in response to a detected animate object. The control system includes a processor configured to execute a machine learning algorithm trained to determine whether the detected object is an animate object to determine whether an animate object is within the field of view. The system provides an output to alert an operator of the working machine if it is determined that an animate object has been detected in the field of view of the at least one camera.

An automatic control determination unit determines whether to start automatic dumping control. A dumping control unit generates a first command to rotate a bucket in a dump direction until an inclination of the bucket reaches a predetermined dumping completion angle upon determining to start the automatic dumping control. The dumping control unit generates a second command to rotate a boom in a raising direction during a period until the inclination of the bucket reaches the dumping completion angle from an inclination at the time of start of the automatic dumping control.

A control device that controls a work vehicle including work equipment includes: a route acquisition unit that acquires a traveling route of a transport vehicle; an area setting unit that sets a limit area for limiting entry of the work equipment along the traveling route; and a signal output unit that outputs a signal for controlling the work vehicle or the transport vehicle on the basis of a relationship between the limit area and the work equipment.

An excavator may perform a finishing operation to prepare a slope while maintaining workability. The excavator includes an undercarriage, a slewing upper structure rotatably mounted on the undercarriage, a boom pivotally mounted on the upper structure, an arm rotatably mounted on a tip end of the boom, a bucket mounted on a tip end of the arm, and a controller. The controller restricts a lowering operation of the boom, so that at least one of a pressing force of the bucket against the ground and a speed of lowering the bucket toward the ground does not become relatively large.

A debris accumulation control system is provided for usage within a work vehicle including an operator station and a work vehicle compartment. In embodiments, the work vehicle debris accumulation control system includes a display device located in the operator station of the work vehicle, a three dimensional (3D) imaging device having a field of view (FOV) encompassing a debris-gathering region of the work vehicle compartment, and a controller operably coupled to the display device and to the 3D imaging device. The controller is configured to: (i) utilize 3D imaging data provided by the 3D imaging device to estimate a debris accumulation risk level within the work vehicle compartment; and (ii) generate a first visual alert on the display device when the debris accumulation risk level surpasses a first predetermined threshold.

A technique is directed to methods and systems of an implement lock-out on lever-controlled machines. A lock-out system can monitor the position of an implement and lock-out the implement control(s) when the implement is within a threshold distance to parts of the machine. The lock-out system can generate an implement lock-out to slow, stop, or reduce the force of a hydraulic valve(s) controlling the implement. The lock-out system can use inputs such as electronic fence blade position system data, articulation angles, wheel lean angles, steering angles, ripper positions, mode selection or similar data to determine to generate the implement lock-out. The lock-out system can generate the implement lock-out by a flow supply shutoff to the implement while maintaining pressure to the steering valve. The lock-out system can send visual or audible notifications to alert the operator of the implement's proximity to the machine or of an implement lock-out.

A loaded machine information acquisition unit acquires position information and azimuth direction information of a transport vehicle. An earth removal position-specifying unit specifies an earth removal position for loading a load target onto the transport vehicle, based on the position information and the azimuth direction information. A bucket position-specifying unit specifies a position of a bucket. An operation signal generation unit generates an operation signal for moving the bucket from the specified position to the earth removal position.

A work machine includes: an informing device that informs an operator; an input device for inputting predetermined information; a notification device that gives a notification to a worker around the work machine; a controller; and a communication device that communicates with a mobile terminal carried by the worker. The controller determines whether or not an approval request for requesting approval of entry into a movable range of the work machine transmitted from the mobile terminal when the worker around the work machine operates the mobile terminal has been received; inform, by using the informing device, that the approval request has been received when it is determined that the approval request has been received; determine whether or not approval operation of approving entry into the movable range has been performed on the input device; set an interpersonal communication level representing a degree of interpersonal communication between the operator and the worker depending on whether or not the approval request has been received and whether or not the approval operation has been performed; decide a mode of notification in accordance with the interpersonal communication level; and give a notification in the mode of notification by using the notification device.

Provided is a construction machine that avoids automatic release of operation restriction involving, for example, sudden acceleration unintended by an operator even when an inclined angle of a vehicle body changes. The construction machine includes a vehicle body 50 configured to operate, 3D sensors (obstacle detection devices) 5, 6, 7, and 8 that detect an obstacle present around the vehicle body 50, an inclined angle determination device (an inclined angle detection device) 9 that detects the inclined angle of the vehicle body 50, and a vehicle body controller (a controller) 14 having an operation restriction function that performs a restriction control to restrict an operation of the vehicle body 50 when the 3D sensors (the obstacle detection devices) 5, 6, 7, and 8 detect an obstacle. When the inclined angle of the vehicle body 50 exceeds a predetermined threshold while the restriction control is not performed with the operation restriction function, the vehicle body controller (the controller) 14 disables the operation restriction function. When the inclined angle of the vehicle body 50 exceeds the predetermined threshold while the restriction control is performed with the operation restriction function, the vehicle body controller (the controller) 14 does not disable the operation restriction function.
