A system may include a first transportation device of a milling machine, a controller, and an inclination control system. The controller can control a construction machine including the first transportation device, which can move the construction machine over an operating surface. The inclination control system includes a first sensor coupled to the first transportation device to sense an orientation of the first transportation device relative to the frame of the milling machine. The controller controls the milling machine based on inclination information received from the inclination control system.

Inclination control for construction machines

A machine for road work can comprise a frame, a plurality of ground engaging units, a plurality of vertically moveable legs, each leg connecting one of the plurality of ground engaging units to the frame, a pair of spatial sensors, such as global navigation satellite system (GNSS) sensors, and a controller configured to, in response to a three-dimensional signal received from each of the spatial sensors, activate at least some of the plurality of vertically moveable legs.

Systems and methods for controlling ground inclination of rotary cutting machines

In one aspect, a method of determining lateral edges of an asphalt mat deposited by a paving machine includes obtaining thermal image data of the asphalt mat at a thermal measuring device associated with the paving machine, and determining, on the paving machine, the lateral edges of the asphalt mat based on a threshold temperature value and the thermal image data. Other aspects include a method of generating a thermal map of an asphalt mat formed by paving machine, and a system for determining lateral edges of an asphalt mat deposited by a paving machine.

Method and system to trim asphalt thermal mapping data

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.

Autowidth input for paving operations

A grade control indicator assembly is disclosed. The grade control indicator assembly may include a keypad to control one or more functionalities of a machine, where the keypad includes a set of grade control light indicators integrated into the keypad, and where the set of grade control light indicators includes a first subset of grade control light indicators for indicating a grade of the machine with respect to a first side of the machine and a second subset of grade control light indicators for indicating the grade of the machine with respect to a second side of the machine.

Grade control indicator assembly

A system may include a first transportation device, a controller, and an inclination control system. The controller can control a construction machine including the first transportation device, which can move the construction machine over an operating surface. The inclination control system includes first and second slope sensors. The first slope sensor is coupled to the first transportation device and the second slope sensor is coupled to the construction machine. The controller controls the construction machine based on inclination information received from the inclination control system.

Systems and methods for implementing a machine control system in a construction machine having an implement with an extender. The machine control system may include an acceleration sensor mounted to the implement and a processor configured to perform various operations. The operations may include determining that the extender is not moving and in response operating under a first control scheme. Operating under the first control scheme may include receiving acceleration data from the acceleration sensor, generating an estimated slope of the implement based on the acceleration data, and modifying a slope of the implement based on the first estimated slope by causing movement of at least one tow arm. The operations may also include determining that the extender is moving and in response operating under a second control scheme. Operating under the second control scheme may include maintaining the slope of the implement substantially constant.
