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.

A motor grader includes a front frame, a rear frame, an actuator that pivots the front frame with respect to the rear frame, an operator operation apparatus, a display apparatus, and a controller. The controller causes the display apparatus to show any one of an image showing a state of pivot and an image different from the image showing the state of pivot, based on a signal from the operator operation apparatus.

A worksite controller can automatically track movement of material on a worksite, based on location information and work event information provided by vehicles on the worksite. The worksite controller can determine and/or use a location of a work tool of a vehicle, rather than coordinates determined by a location sensor mounted elsewhere on the vehicle, to determine when the work tool is located within defined boundaries of work zones associated with material. When the worksite controller determines that the vehicle performed a work event to interact with material while the work tool was within a particular work zone, the worksite controller can automatically update material tracking information associated with the work zone.

A construction equipment includes a work machine which includes a boom, an arm, and a bucket operated by their respective hydraulic cylinder; a control valve for controlling the hydraulic cylinder; an operation lever for outputting an operation signal corresponding to an operation amount of a driver; a work setting unit for setting a work area; a location information providing unit for providing at least one of location information and posture information of the work machine and location information of the work area; and an electronic control unit for outputting a control signal for the control valve according to the signal inputted from at least one of the operation lever, the work setting unit, and the location information providing unit, wherein the electronic control unit calculates an angle between the work area and the work machine, and controls a speed of the work machine based on the calculated angle.

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.

Methods, systems, and apparatus are described herein for providing operational efficiency at a construction site through a connected system of on-board mobile computers.

A system, method, and apparatus can access, via a user interface, route properties of a mine site used for controlling one or more work machines as the work machine(s) travel through the mine site. Access regarding the route properties can include viewing one or more of the properties and/or setting requirements (e.g., restrictions or limitations) for one or more of the properties. A candidate route can be selected, validated, and set as a selected route using the user interface to access route properties associated with the selected route. Requirements can be set for one or more of the route properties using the user interface. The work machines can be controlled to traverse the mine site according to the requirements set for the route properties.

A work vehicle includes a work implement. A control system for the work vehicle includes an operating device that outputs an operation signal indicative of an operation by an operator, and a controller that communicates with the operating device and controls the work implement. The controller determines a target design topography indicative of a target topography. The controller generates a command signal to operate the work implement in accordance with the target design topography. When a tilt angle of the work implement is changed with an operation of the operating device, the controller corrects the tilt angle of the work implement in accordance with the changed tilt angle.

A system for autonomous or semi-autonomous operation of a vehicle is disclosed. The system includes a machine automation portal (MAP) application configured to enable a computing device to (a) display a map of a work site and (b) provide a graphical user interface that enables a user to (i) define a boundary of an autonomous operating zone on the map and (ii) define a boundary of one or more exclusion zones. The system also includes a robotics processing unit configured to (a) receive the boundary of the autonomous operating zone and the boundary of each exclusion zone from the computing device, (b) generate a planned command path that the vehicle will travel to perform a task within the autonomous operating zone while avoiding each exclusion zone, and (c) control operation of the vehicle so that the vehicle travels the planned command path to perform the task.

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.
