ACTIVE PATH MONITORING FOR VIBRATORY SOIL COMPACTORS
Various control systems and methods for a working machine such as a compactor are disclosed. The control system can include any one or combination of components including a controller in communication with at least a steering system and a position sensor. The controller can be configured to: receive position data from the position sensor including during operator implemented steering of the compactor, save the position data to a memory, determine from the position data saved in the memory a possible intent by an operator to create a compaction area, generate a prompt on an operator interface to confirm an actual intent of the operator, and generate a compaction plan for autonomously steering the compactor to compact in the compaction area. The compaction plan can be based at least partially upon the operator implemented steering of the compactor. The controller can implement the compaction plan via autonomous steering.
PAVING MACHINE WITH SMART STEERING CONTROL
A smart steering control system a paving or texturing machine receives path elements corresponding to current and future positions of the machine. By comparing the current and future elements, an expected completion time is derived for exiting the current position and entering the future position; the smart steering control system synchronizes adjustments of the machine's steerable tracks from the current path to the future path. The smart steering control system functions as a virtual tie rod, preventing damage, enhancing the traction control and pulling power of the machine, and preserving the operating life of its components.

A median barrier finishing machine may include a housing configured to encapsulate at least a portion of a median barrier, where the housing comprises a first vertical wall, a second vertical wall, and a horizontal wall. The median barrier finishing machine may include at least one adjustable member configured to couple the housing to the vehicle and retain the housing a predetermined distance relative to the vehicle while the vehicle is in motion. Further, the median barrier finishing machine may include at least one finishing device disposed within the housing, where the at least one finishing device is configured to contact a surface of a median barrier at least partially positioned within the housing and treat the surface as the vehicle moves the housing along a length of the median barrier.

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.
Slipform paver and method for operating a slipform paver
The invention relates to a self-propelled construction machine and to a method for controlling a self-propelled construction machine. The construction machine according to the invention has a position-determining device 13 for determining the position of a reference point R on the construction machine in a coordinate system (X, Y, Z) independent of the construction machine. The position-determining device has a navigation satellite system receiver 14 for receiving satellite signals from a global navigation satellite system 15 (GNSS) and a computing unit 16 which is configured so that the position of a reference point (R) on the construction machine and the orientation (ψ) of the construction machine can be determined based on the satellite signals in a coordinate system (X, Y, Z) that is independent of the construction machine. Moreover, the construction machine has a controller 18 which cooperates with the position-determining device 13 configured to adjust the steering angles of the steerable running gears 3, 4, 6 so that the reference point R of the construction machine moves along a set trajectory T. The computing unit 16 of the position-determining device 13 is configured so that, in a control mode in which the control of the construction machine is not based on the satellite signals of the global navigation satellite system 15, the position (x.sub.n, y.sub.n, z.sub.n) of the reference point (R) relating to the construction machine and the orientation (ψ) of the construction machine are determined in the coordinate system (X, Y, Z) that is independent of the construction machine while the construction machine is moving on the basis of a kinematic model 16A implemented in the computing unit 16 of the position-determining device 13 which describes the position (P) of the reference point (R) and the orientation (ψ) in the coordinate system (X, Y, Z) that is independent of the construction machine depending on the steering angles and the speeds of the running gears 3, 4, 6.
WORK MACHINE STABILITY CONTROL SYSTEM
An autonomous stability control system may include a sensing system configured to collect position and orientation data about a work machine on a construction site and a controller. The controller may be configured to receive or generate a work path plan, operate the work machine according to the work path plan, continually or periodically monitor the orientation data from the sensing system, compare the orientation data to a vibration slope threshold, and, when the orientation data exceeds the vibration slope threshold, deactivate a vibration system of the work machine.
THREE-DIMENSIONAL BRIDGE DECK FINISHER
A bridge paving machine and method for paving a 3D design without vertical profile rails includes converting a desired design into a 3D surface model to account for certain factors known to cause deviations in the paving processes and paving the 3D surface model in the expectation that factors will cause the 3D surface model to deflect into the desired design. An on-board computer system adjusts the 3D surface model in real-time to correct for on-site variables. The on-board computer system receives data from various external sensors, including deflection sensors fixed to girders in the bride structure, and paving machine-based sensors, and uses various predictive models to predict surface deflection based on the sensor data. The 3D surface model is continuously updated based on the predictive models and actual measured deflections.
STEERING CONTROL FOR PAVING MACHINE
A system adjusts an instantaneous turn center for a paving machine having a tow vehicle and a screed assembly towed by the tow vehicle such that no portion of the screed assembly moves backward over freshly laid pavement when the paving machine paves around a curve. The system receives an input from an operator, a sensor, and/or a database. The input includes a distance and a direction from a first vertical axis defined by a traction device of the tow vehicle on a side of the tow vehicle facing the curve, to a second adjusted vertical axis defined by a point at least as far from the first vertical axis as an outer edge of the screed assembly that touches the curve. The system receives the input, and adjusts the instantaneous turn center for the paving machine to coincide with the second adjusted vertical axis.
Systems and methods of visual guidance
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.
