A control system for a work vehicle includes a controller. The controller determines a work zone at a work site. The controller determines a target design topography at least partially positioned below an actual topography at the work site. The controller specifies a non-work zone. The non-work zone is a portion in which the actual topography is positioned below the target design topography in the work zone. The controller modifies the work zone based on the non-work zone. The controller generates a command signal to operate a work implement of the work vehicle according to the modified work zone and the target design topography.

A wheel loader includes: an operator's cab; a front wheel; a front frame configured to support front wheel such that front wheel is rotatable; a bucket; a boom having a distal end connected to bucket, and a proximal end rotatably supported by front frame; a sensor configured to measure a distance between front wheel and a loading target; and a controller configured to control an action of wheel loader. The controller causes wheel loader to perform a predetermined action for collision avoidance on condition that a distance to be measured by sensor when wheel loader travels takes a value less than or equal to a threshold value.

Detecting a surface irregularity on a surface for a vehicle moving forwardly or rearwardly along the surface, the vehicle having a frame supported by wheels and an implement adjustably coupled to the frame. Two of front and rear steering positions and an implement position are used to determine a path of travel of the vehicle. Surface irregularities of the surface within the path of travel are determined which triggers a warning to the vehicle. The speed of the vehicle can be decreased automatically to stop the vehicle before the vehicle impacts the surface irregularity. A vehicle zone of operation is determined based on the path of travel and a corresponding pair of gridlines is displayed on user interface. The pair of gridlines vary in shape, color, position, and orientation as the path of travel changes. The surface irregularity is illuminated relative to the pair of gridlines on the operator display.

A system automatically controls a work machine including a work implement. The system includes a processor. The processor controls the work machine by selectively executing a normal digging mode in order to dig an actual topography at a work site, and a wall digging mode in order to dig a digging wall formed between a plurality of slots by digging the actual topography. When the wall digging mode is executed, the processor acquires starting edge position data indicative of a position of a starting edge of the digging wall. The processor determines a digging starting position based on the position of the starting edge of the digging wall. The processor controls the work machine to dig the digging wall from the digging starting position.

A turfplaner is described comprising a rotational elongated cutter capable of independently altering a cut height of the rotational cutter based on a deviation between cut height and a desired cut profile. A hierarchical controller is in functional communication with the lift mechanism and a laser or GPS guidance system. The laser or GPS receiver is capable of receiving the planer laser beam or GPS signal and the hierarchical controller is capable of determining and minimizing a deviation between the cut height and the desired cut profile based on the laser or GPS receiver location relative to the planer laser beam or GPS signal. At least one autograde device and an autodepth device are in functional communication with the hierarchical controller to activate either on grade, below grade, or above grade control mode.

A controller-implemented method for automated control of at least one of an autonomous or semiautonomous machine to clear at least one windrow along a work surface. The method includes utilizing a visual perception sensor to detect said windrow, generating a plurality of windrow visual detection signals, determining a position of a windrow relative to the machine based upon the plurality of windrow visual detection signals, and generating machine control commands to clear the windrow.

A control system for a work vehicle having a work implement, the control system including: a position measurement unit for measuring a position of a windrow produced by grading work; a work route setting unit for setting a work route based on the position of the windrow that has been measured by the position measurement unit; and a travel control unit for controlling the work vehicle to travel along the work route that has been set by the work route setting unit.

A system for planning an earth-moving operation to be performed by a construction machine having a tool for performing the earth-moving operation and a machine control unit for at least partially controlling the earth-moving operation, the system comprising a measuring system configured for capturing 3D measuring data of an uneven terrain in a surrounding of the construction machine, a context camera having a known position relative to the measuring system and/or the 3D measuring data and being configured for capturing context image data of the terrain, a user interface configured for displaying at least one context image to an operator of the construction machine and for receiving user input from the operator, and a computing unit operatively coupled at least with the measuring system and the user interface.

A motor grader includes a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. A control method performed in the motor grader includes obtaining current topography in front of the motor grader and adjusting the blade angle to an angle in accordance with the current topography by revolving the swing circle.

A control system for a work vehicle includes a controller. The controller determines a work zone at a work site. The controller determines a target design topography at least partially positioned below an actual topography at the work site. The controller specifies a non-work zone. The non-work zone is a portion in which the actual topography is positioned below the target design topography in the work zone. The controller modifies the work zone based on the non-work zone. The controller generates a command signal to operate a work implement of the work vehicle according to the modified work zone and the target design topography.
