Techniques for maintaining vehicle formations
11708094 · 2023-07-25 · ·

A method of maintaining vehicle formation includes receiving a desired formation distance between a lead vehicle and a follower vehicle; receiving a pre-planned path for the follower vehicle; and defining a dynamic zone around a current position of the lead vehicle. The dynamic zone has a boundary characterized by a first radius from the current position of the lead vehicle. The first radius can be substantially equal to the desired formation distance. The method further includes determining a next speed of the follower vehicle based on a current position of the follower vehicle with respect to the boundary of the dynamic zone; determining a commanded curvature of the follower vehicle based on the current position of the follower vehicle with respect to the pre-planned path; and outputting the next speed and the commanded curvature to a control system of the follower vehicle for navigation of the follower vehicle.

AGRICULTURAL METHOD AND SYSTEM FOR PERFORMING THE METHOD

A method, using an autonomous, unmanned device and a control device, includes the steps of automatically harvesting feed crop in a part of a crop field by means of the autonomous, unmanned device; automatically loading the harvested feed crop directly into a storage space provided on the autonomous, unmanned device without said harvested feed crop contacting the soil; choosing a destination location from a feeding location and a stationary crop processing location; automatically transporting the harvested feed crop from the crop field to the chosen destination location by means of the autonomous, unmanned device; and automatically unloading harvested feed from the storage space of the autonomous, unmanned device at the chosen destination location.

EQUIPMENT SETTINGS CONTROL BASED ON AGGREGATED DATA
20230234440 · 2023-07-27 ·

Settings data is collected from a plurality of different agricultural machines and is sorted based on indexing criteria. The sorted data is aggregated to obtain metric values and stored based on the indexing criteria. An agricultural vehicle accesses the indexed, aggregated data to obtain settings data. The agricultural vehicle is controlled based upon the settings data.

Sensor arrangement for an agricultural vehicle
11703880 · 2023-07-18 · ·

A sensor arrangement for an agricultural vehicle includes a first electro-optical sensor including a first field of view having an optical axis, and a second electro-optical sensor including a second field of view having an optical axis. The first and second sensors are spaced apart from one another and oriented such that the optical axes of the two sensors intersect at a distance from the two sensors.

Work machine control based on machine capabilities relative to work assignment criteria
11690320 · 2023-07-04 · ·

A method of controlling a work machine on a worksite includes receiving an indication of a work machine assignment having a worksite location and corresponding assignment criteria associated with completion of the work machine assignment, receiving a set of worksite conditions at the location, and identifying a set of machine capabilities, each machine capability corresponding to operation of a controllable subsystem on the work machine. The method includes generating a likelihood metric indicative of a likelihood that the assignment criteria will be met based on the set of worksite conditions and the set of machine capabilities, comparing the likelihood metric to a threshold, and generating a control signal that controls the work machine based on the comparison.

CLOSED LOOP CONTROL OF FILLING MECHANISMS
20220408645 · 2022-12-29 ·

An agricultural harvester has a frame and a spout that is mounted to the frame. A target landing point indicates a position in a receiving vehicle where material is intended to land. A control system detects an actual landing point and automatically controls the spout based on a difference between the actual landing point and the target landing point.

ROW SENSE OPERATIONS WITH CONTEXT SENSING
20220386527 · 2022-12-08 ·

A computer-implemented method of operating an agricultural work machine is provided. The method includes initiating row sensing guidance for the agricultural work machine to guide steering of the agricultural work machine based at least one signal from a row sensor; obtaining contextual information; determining whether a row is present based on the contextual information; and selectively ignoring the at least one signal from the row sensor based on whether a row is present. An agricultural work machine and a control system for an agricultural work machine are also provided.

Autonomous Operation Method, Work Vehicle, And Autonomous Operation System

A combine harvester is a work vehicle capable of switching between a manual travel mode to travel based on operation of an operation tool including a steering wheel which is a turning operation tool and an autonomous traveling mode to travel based on a predetermined travel route, which includes a controller to function as an autonomous travel controller to control travel of the combine harvester through the autonomous travel mode based on the travel route. The combine harvester is switched from the autonomous travel mode to the manual travel mode without stopping the vehicle when the steering wheel is operated during the autonomous travel mode.

MOBILE AUTONOMOUS AGRICULTURAL SYSTEM AND METHOD

There is provided a mobile autonomous agricultural system comprising: a powered mobile unit for carrying agricultural equipment, and configured to move along rows of crops; at least one laser curtain sensor configured to project a laser curtain away from the mobile unit; a location module configured to monitor a location of the mobile unit relative to a row; a controller configured to control the travel of the mobile unit; a safety module configured to: receive a location signal from the location module related to the location of the mobile unit relative to a row, select a mode of operation to process the laser curtain in a predefined laser curtain pattern, based on the received location signal, each mode of operation corresponding to a different predefined laser curtain pattern, and to generate a safety output in response to determining that the laser curtain is interrupted within the laser curtain pattern.

AUTOMATIC DRIVING METHOD, WORK VEHICLE, AND AUTOMATIC DRIVING SYSTEM

To provide an automatic driving method, a work vehicle, and an automatic driving system, by which it is possible to perform automatic travel with improved operability. A combine is a work vehicle executing an automatic travel, based on a preset travel route, and includes a steering wheel being a turn operation tool that accepts a turn operation to instruct turning of the combine, a control device that functions as an automatic travel control unit that controls the automatic travel of the combine, based on a travel route, and an override button being a turn operation permission unit that permits a turn operation on the steering wheel during execution of the automatic travel. The travel unit does not accept the turn operation under a normal circumstance during execution of the automatic travel but once the override button is operated, accepts the turn operation.
