This summary is illustrative only and is not intended to be in any way limiting. Other aspects, inventive features, and advantages of the devices or processes described herein will become apparent in the detailed description set forth herein, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements.
Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.
Industrial vehicles such as agricultural vehicles 10 (e.g., windrowers, swathers, tractors, tillers, planters, sprayers, combines, and fertilizers, etc.) may be utilized in agricultural applications to facilitate the growing of crops and any other type of agricultural application. Typically, agricultural vehicles 10 may include one or more vehicle control systems which are configured to control the operation of the vehicle to provide auto-guidance for the vehicle. An auto-guidance control system may be described as an automated method for controlling one or more vehicles with a high level of accuracy. The auto-guidance control system may allow the vehicle to steer, turn, and generally operate with at least some level of autonomy with a high level of positioning accuracy. While in use, agricultural vehicles 10 may encounter varying field conditions, boundaries, and obstacles that require a change in the vehicle's path or alter the optimal harvest path in a particular agricultural zone. For example, in the context of mowing, swathing, or baling hay planted in a field utilizing a central pivot irrigation system, pivot tracks (made by the pivot tower when it rotates around the field) designate areas where no crop growth occurs and shape the optimal path that a swather/windrower should travel when navigating the field. In rectangular fields or fields utilizing linear irrigation systems, boarders serve as another field condition that must be accounted for in an autoguidance system of the agricultural vehicle 10. Accounting for field conditions and obstacles allows for pathing with optimal overlap so that all passes are at uniform spacing. Automatically adjusting an autoguidance system to account for pivot tracks and boarders creates more uniformly sized and spaced swaths, increases efficiency by reducing operator time spent steering, and eliminates the need for operators to manually trace pivot tracks and boarders into the auto-guidance system.
In some embodiments, an agricultural vehicle (e.g., a windrower) may include a vehicle control system which may be configured to automatically detect pivot tracks and boarders and indicate their locations to the autonomous guidance system of the agricultural vehicle. The vehicle control system is communicatively coupled to position sensors disposed on the header of a vehicle (e.g., on the hydraulic cylinders of the header). The position sensors detect a change in placement of the header as it floats over a pivot track or boarder, and send the data indicating a change in placement to the auto-guidance controller. The vehicle control system then tracks the location of the displacement via a GPS marker. Once the agricultural machine has passed over multiple pivot tracks or boarders (e.g., when cutting headlands around the pivot towers or a field), the vehicle control system may automatically draw circular indicators for pivot tracks (for central pivot systems) or linear indicators for boarders (for rectangular fields) on the GPS system of the agricultural vehicle. The indicators are then accounted for automatically by the agricultural machine's autoguidance system. In further embodiments, sensors (e.g., GPS markers) are coupled to pivot towers above the pivot tracks of an irrigation system. GPS pathways of the pivot tracks are marked as the irrigation system moves, and indicators of the pivot track are communicated to the vehicle control system. The agricultural machine then immediately enters an autoguidance mode factoring in the location of the pivot towers upon entering the field.
Systems and methods directed to automatically detecting pivot tracks and boarders in agricultural vehicle autoguidance systems are described in the present application. More specifically, an vehicle control system for controlling agricultural vehicles is described that incorporates sensors mounted to the header, hydraulic cylinders, or other components of the agricultural vehicle. Additionally, sensors may be mounted in locations on a pivot tower of an irrigation system to indicate the location of pivot tracks. The vehicle control system receives information about the change in position of the header as it floats over a pivot track or boarder and uses the information to dynamically map full pathways of pivot tracks and boarders. The mapping is used to automatically calibrate and adjust the autoguidance system of the agricultural vehicle. For example, the vehicle control system disclosed herein may include a variety of sensors and a marking circuit which is configured to receive information from the variety of sensors. The marking circuit may be configured to mark locations of pivot tracks and boarders by receiving indications of the displacement of the headers/hydraulic cylinders of the vehicle. Additionally, an auto-guidance controller circuit may receive information from sensors coupled to pivot towers indicating the location of pivot tracks. The auto-guidance controller circuit may then use that information to adjust the agricultural vehicles autoguidance system, create an optimized pathway immediately upon entering a field, and allow for uniform swath spacing and optimized path overlap with minimum interaction from the operator.
For the purposes of the present disclosure, the term “vehicle” refers to any equipment that can be moved (e.g., within a field), regardless of whether the equipment includes a prime mover or other device configured to move the equipment under its own power. For example, the term “vehicle” applies to powered equipment such as a windrower, swather, tractor, combine, harvester, etc., but the term “vehicle” also applies to equipment that moves through the assistance of another vehicle, such as various agricultural or construction implements that are attached/coupled to another vehicle (e.g., implements such as irrigation machinery, soil cultivation implements, planting equipment, harvesting implements, etc. that are attached to and moved by a tractor or other vehicle). Though agricultural vehicles are primarily described in the present disclosure, the systems and methods herein may be applied in a variety of industrial applications including construction.

The communication system 124 may facilitate communication between the agricultural windrower 12 and/or vehicle control system 200 and external systems (e.g., a remote database,, the sensors 120 coupled to the irrigation system 128, etc.). The communication system 124 may be or include wired or wireless communications interfaces (e.g., jacks, antennas, transmitters, receivers, transceivers, wire terminals, etc.) for conducting data communications with other external systems or devices. In various embodiments, communications via communication system 124 is direct (e.g., local wired or wireless communications). Additionally or alternatively, communications via the communication system 124 may utilize a network (e.g., a WAN, the Internet, a cellular network, a vehicle-to-vehicle network, etc.). For example, vehicle control system 200 may communicate with a decision support system (DSS) using a 4G and/or 5G connection (e.g., via a 4G or 5G access point/small cell base station, etc.). In some embodiments, communication system 124 facilitates vehicle-to-vehicle (V2V) and/or vehicle-to-everything (V2X) communication.

In some embodiments, the vehicle control system 200 includes a processing circuit 106 having a processor 108 and a memory 110. In some embodiments, vehicle control system 200 includes one or more processing circuits 106 including one or more processors 108 and one or more memories 110. Each of the processors 108 can be a general purpose or specific purpose processor, an application specific integrated circuit (ASIC), one or more field programmable gate arrays (FPGAs), a group of processing components, or other suitable processing components. Each of the processors 108 is configured to execute computer code or instructions stored in the memory 110 or received from other computer readable media (e.g., CDROM, network storage, a remote server, etc.).
In some embodiments, the memory 110 may include one or more devices (e.g., memory units, memory devices, storage devices, or other computer-readable media) for storing data and/or computer code for completing and/or facilitating the various processes described in the present disclosure. The memory 110 may include random access memory (RAM), read-only memory (ROM), hard drive storage, temporary storage, non-volatile memory, flash memory, optical memory, or any other suitable memory for storing software objects and/or computer instructions. The memory 110 may include database components, object code components, script components, or any other type of information structure for supporting the various activities and information structures described in the present disclosure.

In some embodiments, the memory 110 is shown to include a sensor circuit 112, a marking circuit 114, and an auto-guidance controller circuit 116. In some embodiments, the sensor circuit 112 is configured to receive sensor information about the agricultural windrower 12 such as a change in position of the header 14 or hydraulic cylinder 15 when the windrower 12 travels over a pivot track 136 or field boarder. For example, the sensor circuit 112 may be coupled to a sensor 120 coupled to the hydraulic cylinder/header that is configured to detect a change in position as the header 14 floats over a pivot track 136 or field boarder. The sensor circuit 112 may also be communicatively coupled to sensors 120 (e.g., GPS receivers and the like) coupled to the pivot towers of the irrigation system 128.

In some embodiments, the auto-guidance controller circuit 116 may be configured to dynamically adjust the vehicle control system 200 based on the automatic detection of pivot tracks 136 and field boarders received/determined by the agricultural windrower 12. The auto-guidance controller circuit 116 may facilitate autonomous guidance within the agricultural vehicle 10. Specifically, as the auto-guidance controller circuit 116 determines the presence of one or more pivot tracks 136 or field boarders, the auto-guidance controller circuit 116 generates one or more mowing/raking/swathing/baling paths to optimize overlap and maintain uniform swath spacing while the windrower is in use in the agricultural zone 16.

At step 804, the vehicle control system 200 may receive sensor information for an agricultural vehicle 10, in some embodiments. As explained above, the vehicle control system 200 includes the sensor circuit 112 which is communicably coupled to one or more sensors 120 associated with the agricultural windrower 12. The sensor circuit 112 may be structured to receive, aggregate, and store sensor information about the agricultural windrower 12. In some embodiments, the sensor information indicates a change in position of a header 14 as it passes over a pivot track 136, check 148, or boarder. In some embodiments, the sensor information may include data from a hydraulics sensor assembly which will provide information about how the agricultural vehicle 10 or the implement attached to the agricultural vehicle 10 is being operated (e.g., detecting a change in position of the hydraulics cylinder 15 as the windrower 12 passes over a pivot track 136 or boarder). For example, an agricultural vehicle 10 may pass over a pivot track 136. In such an case, the vehicle control system 200 may receive information from a sensor 120 which may allow the vehicle control system to determine that a location associated with a pivot track 136 should be marked (e.g. on a GPS map). In other embodiments, the vehicle control system may receive sensor information from sensors 120 coupled to an irrigation system 128. The sensors 120 coupled to the irrigation system 128 may be GPS receivers or the like and indicate the location of the pivot tracks 136 beneath the irrigation system 128. The sensor information described herein is only exemplary and not meant to be limiting. In some embodiments, a first sensor 120 and a second sensor 120 are coupled to the agricultural vehicle 10 (e.g., a header of the agricultural vehicle 10, a hydraulic cylinder of the agricultural vehicle 10, etc.) and a third sensor 120 is coupled to an irrigation system (e.g., a pivot tower, a support tower, a wheel, etc.), and the first sensor 120, the second sensor 120, and the third sensor 120 are configured to detect a change in position (e.g., a change in position of the header of the agricultural vehicle 10, a change in position of the hydraulic cylinder, a change in position of the pivot tower, etc.).
At step 808, the vehicle control system 200 may receive an indication to mark a geographic position. As explained above, the vehicle control system 200 includes the marking circuit 114 configured to receive the vehicle information from the sensor circuit 112 and use that information to place a mark on a GPS, log a location in a database, etc. indicative of the geographic position of a pivot track 136 and/or a boarder. For example, the marking circuit 114 may receive sensor information detecting a displacement of the header 14 or the hydraulic cylinder 15 as the windrower 12 travels over a pivot track 136. The marking circuit 114 may use the sensor information to indicate that the location should be marked on the GPS unit 132 of the windrower 12.
At step 812, the vehicle control system 200 marks a plurality of geographic positions associated with the locations of one or more pivot tracks 136 and/or one or more boarders. Specifically, each time the sensors 120 detect a change in position and an indication to mark a geographic position is received by the windrower 12, the vehicle control system 200 marks the geographic position associated with the pivot track 136 and/or the boarder. The vehicle control system 200 may compare the marked geographic positions to known coordinates, headland cutting paths, etc. The vehicle control system 200 may also overlap the marked locations on a GPS map, may store the marked geographic coordinates in the memory 110, etc. The vehicle control system 200 may also be configured to designate a start time and an end time for marking a plurality of geographic positions associated with the pivot tracks 136 and/or boarders. For example, the vehicle control system 200 may receive an indication (e.g., via a user input on the user interface 122) that the operator is beginning the process of cutting headlands in the agricultural zone 16. The vehicle control system 200 may designate the beginning of this process as the start time to begin marking geographic positions. Likewise, the vehicle control system 200 may receive an indication (e.g., via a user input on the user interface 122) that the operator has completed the process of cutting headlands in the agricultural zone 16. The vehicle control system 200 may designate the end of this process as the end time to conclude marking geographic positions.
At step 816, the vehicle control system 200 may determine a complete location of one or more pivot tracks 136 and/or one or more boarders based on the plurality of marked geographic positions. For example, the marking circuit 114 may have designated a plurality of geographic positions associated with a pivot track 136 each time the sensors 120 passed over the pivot track 136 when cutting headlands, as shown in
At step 820, the vehicle control system 200 may populate the auto-guidance system of the agricultural windrower 12 with the complete location of one or more pivot tracks 136 and or boarders. As mentioned above, the vehicle control system 200 includes the auto-guidance controller circuit 116 which is configured to receive data from the marking circuit 114 and update the control of the windrower 12 based on the indication of geographic positions indicative of pivot tracks 136 and boarders. In some embodiments, the auto-guidance controller circuit 116 updates the vehicle control system 200 by overlaying the GPS unit 132 with the automatically calculated locations of the pivot tracks 136 and/or boarders. For example, as the auto-guidance controller circuit 116 receives a complete data set of marked geographic positions, the auto-guidance controller circuit 116 generates one or more boundaries on the GPS that are factored in to the automatic guidance system of the windrower. In some embodiments, the population of the complete locations of pivot tracks 136 and boarders allows for the automatic guidance system to determine optimal pathing and to maintain uniform swath spacing with little user input immediately upon entering the field.
