Abstract: A method for controlling an autonomous construction vehicle may include defining a boundary of a construction site and automatically creating a site plan for navigating the autonomous construction vehicle within the boundary. The site plan includes a work area within the boundary, a maneuver area positioned between the work area and the boundary, a start point for the autonomous construction vehicle, and a path for the autonomous construction vehicle. A controller can then provide the site plan for review and activate autonomy mode to automatically control the autonomous construction vehicle according to the site plan.

Abstract: A system and method for responding to objects encountered by autonomous machines at a worksite. Sensors at the worksite gather sensor data that may be used by one or more processors to identify an object or obstacle at the worksite and an associated location. The sensors may be disposed on an autonomous machine operating at the worksite. The system and method include determining, based on the sensor data, an object classification for the object and/or obstacle and determining, based on the object classification and the sensor data, a remediation procedure to remove the object from the path and enable the autonomous machine to complete the work plan. The system and method further include determining a second machine included in the remediation procedure from a set of machines located at the worksite and causing the second machine to perform the remediation procedure.

Abstract: A system for assisting an asphalt compactor in performing a directional change can include a controller configured to perform a turn-out for the asphalt compactor by steering the asphalt compactor at a desired turning angle on an asphalt mat; the controller configured to turn off a vibratory system for the asphalt compactor during the turn-out; the controller configured to slow down and stop the asphalt compactor after a desired distance into the turn-out; and the controller configured to move the asphalt compactor in an opposite direction and restart the vibratory system.

Abstract: An automatic mode resume system for a mobile machine and a method for resuming a job performed on a job site by a mobile machine is disclosed. The method may include: storing an interrupted status of the job being performed by the mobile machine upon interruption of the job for the job site; displaying multiple job sites on a display of the machine, each job site including a stored interrupted location and resume location; receiving a selection of the job site from a user input; displaying the interruption location and resume location for the selected job site on the display; and conditioning a resuming of the job in an auto mode of the machine based on whether the machine is positioned adjacent the interruption location or resume location at the selected job site.

Abstract: A method includes receiving first information indicative of a location of a perimeter of a worksite surface, and receiving second information indicative of compaction requirements specific to the worksite surface. The method also includes generating a compaction plan based at least partly on the first and second information. Such a compaction plan includes a travel path for a compaction machine. In such a method, the travel path is substantially within the perimeter of the worksite surface. The method also includes causing at least part of the travel path to be displayed via a control interface of the compaction machine. The method further includes receiving an input indicative of approval of the travel path, and controlling operation of the compaction machine on the worksite surface, in accordance with the compaction plan, based at least partly on receiving the input.

Abstract: A test system includes a master electronic control module (ECM) configured to receive user input for performing a test action. The master ECM determines one or more subsystem ECMs associated with the requested test action and a sequence of operations to be controlled by the subsystem ECMs to perform the requested test action. The master ECM provides instructions to the subsystem ECMs to perform the operations, along with parameters for those operations. The master ECM may determine whether a test action is appropriate to perform, based on sensor data, before instructing subsystem ECMs to perform the operations of the test action.
