An agricultural method for automatically controlling a position of a harvesting implement of an agricultural harvester, where the harvesting implement may be movably supported relative to a chassis of the agricultural harvester, and where a cab may be movably supported relative to the chassis, may include receiving inertial movement data from an implement-based inertial measurement unit (IMU) supported on the harvesting implement and inertial movement data from a vehicle-based IMU supported on at least one of the cab or the chassis of the agricultural harvester. The method may further include determining a relative movement parameter of the harvesting implement relative to the at least one of the cab or the chassis based at least in part on the inertial movement data. Additionally, the method may include controlling an operation of an implement actuator based at least in part on the relative movement parameter.

Systems, methods, and apparatuses for automatically controlling a position of a reel relative to wing of an agricultural header in response to movement of the wing are disclosed. In some instances, a position of the reel, such as a portion of the reel, is located at a different position relative to the wing based on an amount of articulation of the wing, such as an amount of angular displacement of the wing relative to a datum, such as a center frame of the header.

A control system for controlling pivoting of a header of an agricultural harvester. The control system includes first, second, and third header height sensors, each for mounting to a respective point on the header, each configured to provide a respective header height signal representing a respective measured header height of their respective point on the header above a ground plane. The control system further includes a header angle sensor configured to provide a header angle signal indicative of a pivot angle of the header about an axis; and a processor configured to: receive the signals; calculate an estimated first header height based on the pivot angle and the second and third header heights; determine a replacement first header height by selecting the smallest of the estimated and the measured first header height; and generate a control signal based at least on the replacement first header height.

An automated implement control system includes one or more distance sensors configured for coupling with an agricultural implement. The one or more distance sensors are configured to measure a ground distance and a canopy distance from the one or more sensors to the ground and crop canopy, respectively. An implement control module is in communication with the one or more distance sensors. The implement control module controls movement of the agricultural implement. The implement control module includes a confidence module configured to determine a ground confidence value based on the measured ground distance and a canopy confidence value based on the measured canopy distance. A target selection module of the implement control module is configured to select one of the measured ground or canopy distances as a control basis for controlling movement of the agricultural implement based on the comparison of confidence values.

An agricultural vehicle header suspension having a frame, a plurality of supports extending forward from the frame, an anchor plate, a frame pivot joining the frame to the anchor plate to be rotatable about a frame pivot axis, a frame actuator connected between the anchor plate and the frame and configured to resiliently hold the frame at a predetermined position relative to the anchor plate, and to allow the frame to move through a range of motion relative to the anchor plate, upon compression and/or extension of the frame actuator. The frame actuator may be, for example, at least one single-acting hydraulic actuator, mechanical spring, or a pneumatic cylinder.

A header for a harvesting machine which includes one or more crop-engaging components and a sensing unit positioned within a flowpath of material and downstream of at least one of the one or more crop-engaging components. The sensing unit is configured, in use, to measure an impact parameter indicative of a force and/or frequency of material incident on a detection surface of the sensing unit in order to determine a measure of grain loss associated with the header.

A system for controlling harvesting implement height of an agricultural harvester may include a computing system configured to monitor the height of a harvesting implement of the harvester relative to a field surface based on the received sensor data. Additionally, the computing system may be configured to determine an implement height error signal by comparing the monitored height of the harvesting implement to a predetermined target height. Moreover, the computing system is configured to divide the determined implement height error signal into a first and second frequency portions, with the second frequency portion having a greater frequency than the first frequency portion. Furthermore, the computing system is configured to control the operation of first and second actuators of the harvester based on the first and second frequency portions of the implement height error signal, respectively.

A driver assistance system of an agricultural harvesting machine with a harvesting header designed as a draper is disclosed. The driver assistance system comprises a memory for storing data and a computing device for processing the data saved in the memory. The draper comprises a central belt and at least one transverse conveyor belt arranged on the left side and the right side of the central belt for conveying the harvested material to the central belt. The draper forms, together with the driver assistance system, an automatic draper. The computing device operates the automatic draper as a characteristic diagram controller using the saved characteristic diagrams, with the automatic draper optimizing operating parameters of the draper and specifying the optimized operating parameters for the draper. The characteristic diagrams describe the relationship between the operating parameters and quality parameters, and a control characteristic curve is assigned to the particular characteristic diagram.

An agricultural machine comprises a carrier vehicle and an attachment is disclosed. The attachment is pivotably guided on the carrier vehicle about an axis extending in the direction of travel of the carrier vehicle. To the right and left of the axis, a support wheel is connected to the attachment via a damped, compressible arm. A control circuit is configured to decide whether a pivoting motion of the attachment about the axis is or is not desirable and, in the case that the pivoting motion is desirable, the arm that is compressed by the pivoting motion is switched from a strongly dampened compressible state to a substantially undampened state.
