A control and/or regulating system for an agricultural device includes a distributor linkage for spreading material, such as fertilizer, pesticide or seed, which extends transversely to the direction of travel and has a central part and two lateral arms connected to the central part with a plurality of arm sections which are foldable in towards one another in the transport position and foldable out in the working position and are connected by joints. At least one hydraulic device is associated with each arm. The hydraulic device comprises a hydraulic. The control and/or regulating system comprises a sensor device configured to detect a pressure change occurring at the respective hydraulic and a data processing unit configured to process signals of the sensor device and, on the basis thereof, to generate a control signal for the respective hydraulic device.

Locations of seeds in a field can be identified using event-based processing or frequency-based processing. A material is applied to the field, based upon the seed locations.

A drive circuit for controlling a solenoid valve having a solenoid coil and a poppet that translates therein is provided. The drive circuit includes a supply bus, a return bus, a flyback circuit, and a switch. The supply bus is configured to couple the solenoid coil to a power supply and supply a coil current. The return bus is configured to provide a ground path for the coil current. The flyback circuit is coupled in parallel to only the solenoid coil. The flyback circuit includes only a bipolar diode. The switch is coupled in series with the solenoid coil and configured to couple and decouple the solenoid coil to the return bus.

An agricultural sprayer system is provided herein that can include a boom assembly having a frame and a boom arm operably coupled with the frame at one end portion thereof. Outer and inner nozzle assemblies can each be supported by the boom arm. The inner nozzle assembly is inboard of the outer nozzle assembly. A sensor can be operably coupled with the boom assembly and configured to capture data associated with the boom arm. A computing system can be communicatively coupled to the sensor. The computing system can be configured to calculate a boom arm movement from a default axis based on the data from the sensor and regulate the outer and inner nozzle assemblies at differing flow rates when the movement exceeds a predefined range.

A liquid metering system for an agricultural implement is modular, having one or more metering pumps for each crop row. The motors and pumps are individually controlled for precise application of the liquid input and are preferable electrically driven. A controller is configured to send commands including both positional and time components to the motors. The motors respond to the commands by changing in position, e.g., an angular position, across the given time.

A controller for an agricultural sprayer machine is configured to receive for each of a plurality of nozzle sets a respective upper pressure limit, a nozzle reference flow, and a nozzle reference pressure. For each one of the plurality of nozzle sets, a speed setpoint is calculated based upon the application rate setpoint, the nozzle reference flow, the nozzle reference pressure, and the product pressure setpoint.

A method of automatically selecting a nozzle set from a plurality of nozzle sets on an agricultural spraying machine is provided. The method includes receiving an application rate setpoint, and for each nozzle set an upper pressure limit, a lower pressure limit, a nozzle reference flow, and a nozzle reference pressure. A speed range is calculated for each nozzle set, wherein each speed range comprises a lower speed limit and an upper speed limit. One of the nozzle sets is selected based upon a sensed forward speed and the calculated speed ranges.

Described herein are systems, methods, and other techniques for damping oscillations of an implement of a vehicle while the vehicle is moving. Sensor data is captured using one or more sensors that are attached to the vehicle. The sensor data is analyzed to extract one or both of symmetric oscillation information or asymmetric oscillation information. One or both of a speed damping signal or a steering damping signal are generated based on analyzing the sensor data. The speed damping signal is generated in response to extracting the symmetric oscillation information and the steering damping signal is generated in response to extracting the asymmetric oscillation information. A movement of the vehicle is modified using one or both of the speed damping signal or the steering damping signal.

An agricultural applicator, that applies material to an agricultural field, includes an on-board, real-time image sensor that senses targets for the material to be applied. A controller controls applicators, such as nozzles or other applicators, to apply the material to the sensed targets

A farming machine includes one or more image sensors for capturing an image as the farming machine moves through the field. A control system accesses an image captured by the one or more sensors and identifies a distance value associated with each pixel of the image. The distance value corresponds to a distance between a point and an object that the pixel represents. The control system classifies pixels in the image as crop, plant, ground, etc. based on the visual information in the pixels. The control system generates a labelled point cloud using the labels and depth information, and identifies features about the crops, plants, ground, etc. in the point cloud. The control system generates treatment actions based on any of the depth information, visual information, point cloud, and feature values. The control system actuates a treatment mechanism based on the classified pixels.
