摘要: A control system for a construction machine is disclosed. The control system may comprise a controller configured to: receive work parameters associated with working of the worksite surface by a surface-working member; generate an edge-to-edge work plan of the worksite surface, the edge-to-edge work plan comprising a plurality of paths each having a center-line-of-travel, wherein one of the plurality of paths includes a first outer edge defined by a first boundary side and another includes a second outer edge defined by a second boundary side; and activate the construction machine to traverse the center-line-of travel of each of the plurality of paths. The plurality of paths may comprise a first path and a second path that includes a second path overlap-section that overlaps the first path, wherein a width of the second path overlap-section varies along a length of the second path.

摘要: Systems and techniques are described for implementing autonomous control of powered earth-moving vehicles, including to automatically determine and control movement around a site having potential obstacles. For example, the systems/techniques may determine and implement autonomous operations of powered earth-moving vehicle(s) (e.g., obtain/integrate data from sensors of multiple types on a powered earth-moving vehicle, and use it to determine and control movement of the powered earth-moving vehicle around a site), including in some situations to implement coordinated actions of multiple powered earth-moving vehicles and/or of a powered earth-moving vehicle with one or more other types of construction vehicles. The described techniques may further include determining current location and positioning of the powered earth-moving vehicle on the site, determining a target destination location and/or path of the powered earth-moving vehicle, identifying and classifying obstacles (if any) along a desired path or otherwise between current and destination locations, and implementing actions to address any such obstacles.

摘要: A shovel includes a lower traveling body, an upper turning body mounted on the lower traveling body, an attachment attached to the upper turning body, and a control device mounted on the upper turning body and configured to assist an excavating motion with the attachment. The control device is configured to derive a target excavation depth based on the hardness of an excavation target.

摘要: One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

摘要: A system and method are provided for determining mistrack conditions in work vehicles such as excavators having first and second tracks. A controller uses data from onboard sensors (e.g., cameras, lidar) having an external field of view to detect a first position of, e.g., a track of the work vehicle relative to a first external point in a local reference system independent of a global reference system and to detect, upon the work vehicle having advanced from the detected first position a predetermined distance, a second position of the at least first component of the work vehicle relative to a second external point in the local reference system. The controller further determines an amount of mistrack error corresponding to a difference between the detected second position and an expected second position, and generates an output signal based on the determined amount of mistrack error.

摘要: A contact of an attachment with an obstacle is suppressed, and concurrently, a wasteful motion of the attachment is suppressed. When determining that an obstacle specific portion exists between a start point and an end point, a controller sets an avoidance path as a target path. The avoidance path is a path along which an attachment specific portion moves from the start point to the end point while the attachment is led to an avoidance operation of avoiding the obstacle. When determining that the obstacle specific portion does not exist between the start point and the end point, the controller sets a non-avoidance path as the target path. The non-avoidance path is a path along which the attachment specific portion moves from the start point to the end point while the attachment is not led to the avoidance operation.

摘要: A work vehicle includes a work implement. A control system for the work vehicle includes a controller. The controller acquires an end position and a target distance of work performed by a work vehicle. The controller determines, as a start position, a position that is away from the end position by the target distance. The controller generates a command signal to start work from the start position toward the end position and to operate the work implement according to a target design topography. The controller modifies the target distance based on a result of the work.

摘要: A controller obtains topographical data indicative of the topography of a work site. The controller obtains material data indicative of the position of a material. The controller computes an evaluation function based on the material data for each of a plurality of candidates of the travel path to be decided from the topographical data. The evaluation function includes a material function pertaining to an amount of the material. The controller decides a candidate having a smallest evaluation function of the plurality of candidates as the travel path.
