Abstract: Method for locating a vehicle, such as a crawler vehicle and in particular a snow grooming vehicle, within a working region, the working region comprising at least one reference element. The method comprising: acquiring a reference model of the working region comprising reference data relating to the at least one reference element; detecting, via at least one sensor of the vehicle, data relating to an area of the working region surrounding the vehicle; comparing the data detected by the at least one sensor with the reference data to verify whether at least a part of the data detected by the at least one sensor corresponds to the reference data; and determining a position of the vehicle within the working region on the basis of the comparison between the data detected by the at least one sensor and the reference data.

Abstract: In some implementations, the EMV uses a calibration to inform autonomous control over the EMV. To calibrate an EMV, the system first selects a calibration action comprising a control signal for actuating a control surface of the EMV. Then, using a calibration model comprising a machine learning model trained based on one or more previous calibration actions taken by the EMV, the system predicts a response of the control surface to the control signal of the calibration action. After the EMV executes the control signal to perform the calibration action, the EMV system monitors the actual response of the control signal and uses that to update the calibration model based on a comparison between the predicted and monitored states of the control surface.

Abstract: A system for generating a work plan for autonomous operation of a compactor in tandem with an earthmoving machine includes a first controller that receives information pertaining to a work area on which the earthmoving machine is required to perform at least one operation. The system also includes a central controller that receives, from the first controller, information pertaining to the work area on which the earthmoving machine is required to perform the at least one operation and analyzes the work area for virtually segmenting the work area into a plurality of virtual work areas. The central controller also receives, from the first controller, data indicative of a movement of the earthmoving machine through each virtual work area from the plurality of virtual work areas and determines an optimal direction of movement for the compactor based on the data indicative of the movement of the earthmoving machine.

Abstract: A method and apparatus for installing a monitoring cable or other utility near an existing pipeline. An electromagnetic signal may be induced on the pipeline. Sensors disposed on an installation vehicle communicate with a processor to determine a distance and orientation of the vehicle relative to the pipeline. A plow or other digging tool opens a trench and installs the cable along a path disposed next to the pipeline within an acceptable distance range from the pipeline. The vehicle may be remotely or automatically operated.

Abstract: An obstacle monitoring device includes a first object detecting section which detects a relative position of a first object located ahead in a moving direction of a vehicle, based on output data of a first moving-direction monitoring sensor, a second object detecting section which detects a relative position and profile of a second object, based on output data of a second moving-direction monitoring sensor which has a higher spatial resolution than the first moving-direction monitoring sensor, an interference determination section that determines whether the vehicle will interfere with the first object and also determines identity between the first object and the second object, and a profile determination section that, if the interference determination section has determined that the first object and the second object are identical to each other, determines whether the profile of the second object will allow the vehicle to pass over the second object.

Abstract: A work machine control system includes a shape detection unit and a construction information generation unit. The shape detection unit detects an object to be constructed and outputs shape information representing a three-dimensional shape of the object. The construction information generation unit acquires the shape information from the shape detection unit and determines, using the shape information, target construction information as a target of construction of the object to be constructed.

Abstract: A surveying system is provided having a work machine with at least one sensor configured to produce a signal indicative of a longitudinal pitch of the work machine and a lateral roll of the work machine. The work machine additionally includes a locating device configured to determine the location of the work machine, a communicating device configured to communicate over a network, and a controller in communication with the at least one sensor and the locating device. The controller is configured to receive the signals from the at least one sensor, create survey data by linking the signals with the location of the work machine, and communicate the survey data using the communicating device over the network to one or more offboard controllers. At least one offboard controller is configured to compare the survey data to one or more threshold values, calculate variances, and generate a map displaying the variances.

Abstract: In order to control a technical system, a user control variable is read in and a plurality of control variable variants of the user control variable are generated. A respective trajectory of the technical system is extrapolated for the user control variable and for the control variable variants, for which a respective reliability is evaluated. Furthermore, a respective distance of each control variable variant to the user control variable is determined. The user control variable is then selected as a control signal for the technical system in the event that the trajectory extrapolated for the user control variable is evaluated as reliable. Otherwise, a control variable variant with an extrapolated trajectory evaluated as reliable is selected from the control variable variants as a control signal, wherein a control variable variant with a low distance is preferably selected. Finally, the control signal for controlling the technical system is emitted.

Abstract: According to one embodiment, a fully-autonomous vehicle, when properly equipped, can be used to clear snow, hail, leaves, and/or other debris from a driveway, roadway, parking lot, etc. For example, a vehicle capable of fully autonomous operation can operate in a “snow plow mode.” In such operations, the vehicle can identify, or be informed of, weather conditions such as snow that would impede travel on paved surfaces such as driveways and roads. When such conditions exist and if the vehicle is properly equipped with a plow or other snow removal equipment, the vehicle and operate in an autonomous manner to clear the user's driveway and/or one or more other driveways, roadways, parking lots, or other paved surfaces depending upon prior permission from the vehicle's owner and based on a variety of factors.
