Abstract: In some implementations, a controller may cause a gearbox coupled to a rotor to shift between a first gear ratio and a second gear ratio one or more times. The controller may obtain a first set of position data that identifies respective first positions of a gear selector of the gearbox for each shift to the first gear ratio, and a second set of position data that identifies respective second positions of the gear selector of the gearbox for each shift to the second gear ratio. The controller may determine a first calibrated position of the gear selector for a shift to the first gear ratio based on the first set of position data and a second calibrated position of the gear selector for a shift to the second gear ratio based on the second set of position data.

Abstract: A system, apparatus, and method can control one or more screed extensions or extenders of a paving machine. Such control can include identifying a location of an undesirable surface condition of a mat paved on a base by the paving machine using data from one or more sensors associated with a screed extension; characterizing the undesirable surface condition of the mat; and adjusting a height and/or an angle of attack of an extension plate of the screed extension to prevent future occurrences of the undesirable surface condition responsive to the identification and characterization of the undesirable surface condition. The location of the undesirable surface condition can represent a start of the undesirable surface condition in a transverse direction of the paving machine and can be associated with either an interface between the screed extension and a main screed or outward of the interface, along a length of the extension plate of the screed extension.

The requested mode of operation may be one of the plurality of modes. The controller may selectively deny the request or enable the machine to perform the action based on a priority assigned to a current mode of operation of the machine and a priority assigned to the requested mode of operation.

The method also includes receiving second location information from a second vehicle, and associating the second vehicle with a second project. The method further includes providing, to an electronic device, instructions to output a user interface that includes a map, and a first visual indicia displayed on the map at a first location corresponding to the first location information, where the first visual indicia indicates that the first vehicle is associated with the first project.

Abstract: A method includes performing, with a compacting machine, a first pass to compact a first portion of a work area to compact a first lane. A guidance system acquires position information representing the first compacted lane. A second pass is performed to compact a second portion of the work area adjacent the first portion. The guidance system acquires current position information of the machine representing current positioning of the machine during the second pass. Comparing the position information of the machine representing the first compacted lane with the current position information, determines whether the current positioning overlaps the first compacted lane a specified amount. When the second pass is determined to overlap the first compacted lane, in-compliance visual indicia is generated. When the second pass is determined to not overlap the first compacted lane with the specified amount, out of compliance visual indicia is generated.
