  • Patent number: 10959377
    Abstract: This disclosure relates to a system for scanning crops. A line scan distance sensor measures a distance of the crops from the sensor and generates distance data indicative of the distance of the crops from the sensor at a measurement angle. A mover system moves the line scan distance sensor or the crops perpendicular to the distance of the crops from the sensor. A rotary encoder associated with the mover system generates movement data indicative of a movement of the distance sensor or the crops perpendicular to the distance of the crops from the sensor. A data collector associates the distance data from the distance sensor with relative positioning data based on the movement data from the rotary encoder and stores the distance data associated with the relative positioning data on a data store. The system allows accurate relative spatial alignment of sequential line scans. As a result, an extremely high resolution in the direction of movement can be achieved.

  • Patent number: 10845208
    Abstract: Systems and methods for estimating a dump location of material dumped by a transport vehicle are disclosed. A system may receive information that identifies a location of a paving machine, and may receive multiple data points associated with the transport vehicle. Each data point may indicate a respective location of the transport vehicle and a corresponding time at which the transport vehicle was at the respective location. The system may identify a subset of the multiple data points that indicate respective locations of the transport vehicle within a threshold proximity of the location of the paving machine. The system may estimate the dump location of the material dumped by the transport vehicle based on at least one of a set of locations indicated by the subset of data points or a set of times indicated by the subset of data points, and may output information that identifies the dump location.

  • Patent number: 10832351
    Abstract: A sensing system bias is reduced across a first agricultural machine and a second agricultural machine. A collection of agronomic data is accessed, that is indicative of an estimated crop yield. The collection that is accessed, for example, includes at least a first set of data sensed by the first agricultural machine and a second set of data sensed by the second agricultural machine. In addition, the first and second sets of data can be scaled based on a yield correction factor. A bias between the scaled first set of data and the scaled second set of data is determined, and a smoothing operation is performed on the scaled first and second sets of data.

  • Patent number: 10829121
    Abstract: Described herein are technologies relating to controlling an autonomous vehicle based upon a computed lane boundary. The computed lane boundary defines a travel path for the autonomous vehicle when the autonomous vehicle turns across a lane of traffic at an intersection of two or more roadways. The autonomous vehicle navigates turn based upon the computed lane boundary, which allows the autonomous vehicle to enter the intersection without crossing into a lane of oncoming traffic.

  • Patent number: 10822769
    Abstract: An earthmoving machine includes a work implement, a distance calculation unit, and a hydraulic cylinder control unit. The work implement includes a boom, an arm, and a bucket. The distance calculation unit calculates a distance between a monitoring point in the bucket and design topography representing an aimed shape of a land grading target. The hydraulic cylinder control unit outputs a command signal for lowering the boom when the distance between the monitoring point and the design topography is equal to or smaller than a prescribed value and when the bucket is expected to move in such a direction that the monitoring point moves away from the design topography as a result of an operation of the arm.

  • Patent number: 10822771
    Abstract: A sensor outputs a signal indicating an excavation start position at which a work implement starts excavation. A controller determines an inclination angle of a virtual design surface so that an amount of soil between the virtual design surface extending from the excavation start position and a current landscape matches a predetermined target amount of soil. The controller generates a command signal that causes the work implement to move along the virtual design surface extending from the excavation start position in a direction inclined at the inclination angle.

  • Patent number: 10813264
    Abstract: The present inventors have recognized that hydraulic cylinders for raising and lowering ground engaging tools of an implement can be synchronously controlled with respect to a prioritized primary set of tools, such as a section of tillage shanks for ripping compacted soil, which cylinder adjustment affects all other sections due to the arrangement of the primary set on the frame. A user can electronically command new ground engaging depths for the primary set and/or any secondary set of ground engaging tools. If the primary set is updated, the system can synchronously control the primary set and the other sections to adjust respective cylinders to achieve desired depths. However, if only a second set is updated, and not the primary set, the system can control only the second set to adjust its cylinder to the desired depth without affecting the primary set or any other second set.
