A ground surface treatment vehicle and systems and methods using the same. In some embodiments, the vehicle may be adapted to autonomously or semi-autonomously identify and optionally treat target areas such as divots on turf surfaces. The vehicle may identify the target area via onboard or remote sensors and autonomously treat the target area by providing a treating material such as infill, seed, particulate matter, and liquids.

A road paver comprises a paving screed, wherein the paving screed comprises a tamper, and the road paver further comprises a GNSS receiver and a material conveyor. In addition, the road paver comprises an electronic control system, which comprises a memory and a data processor, wherein digital construction data, in particular a target height profile of a road surface to be paved, a target layer thickness of paving material and, if necessary, a height profile of a roadbase are stored in the memory. The control system is configured to automatically control compaction performance of the paving screed as a function of the target layer thickness in order to pave the paving material for the respective local coordinate point of the road paver determined by the GNSS receiver.

A system of differential working is provided wherein a controller of a construction machine is provided with a working depth data set and with a design surface data set. A location of the construction machine within a reference system external to the construction machine is determined, for example using a global navigation satellite system. The controller may determine the desired working depth at the current locations of the ends of the working implement from the working depth data set. The controller may determine the desired cross-slope at the current location of the working implement from the design surface data set. The desired working depths and the desired cross-slope may be communicated to a grade control system of the controller.
