Abstract
A paving machine may include a frame, a screed, sensor devices, and a control unit. The screed may include a main section, a first extension, and a second extension. The sensor devices may output a first sensor signal corresponding to a position of the first extension and a second sensor signal corresponding to a position of the second extension. The control unit may receive the first and second sensor signals, determine a screed width based on the first and second sensor signals, receive location data corresponding to a location of the paving machine, determine locations of the first and second extensions based on the screed width and the location data, generate a boundary map based on the locations of the first and second extensions, and cause an action to be performed based on the boundary map.
