Methods, systems, apparatus, and articles of manufacture to monitor performance of an agricultural vehicle are disclosed. An example apparatus disclosed herein includes memory, machine readable instructions, and programmable circuitry to execute the machine readable instructions to access an image captured by a camera associated with an agricultural vehicle, determine a harvesting operation metric corresponding to the image, generate interactive display information by storing the image in association with the harvesting operation metric, and cause presentation of the interactive display information via a user interface.

A control device for controlling a self-propelled combine harvester. The combine harvester comprises a draper having a plurality of conveyor belts driven at a belt speed for collecting and conveying harvested material to a conveying device in the feed channel of the combine harvester, a plurality of working units arranged or positioned downstream from the feed channel for processing the picked-up harvested material, and a drive motor for driving the draper, the conveying device, the working units and a travel drive for operating the combine harvester at a driving speed which is regulated by the control device. The control device is configured to determine the utilization of the drive motor during harvesting mode and to automatically reduce the belt speed of the conveyor belts of the draper when a first limit value for a peak capacity of the drive motor saved in the control device is exceeded.

A set of sensor inputs are received in an agricultural machine. The sensor inputs are indicative of sensed or measured variables. A probabilistic control system probabilistically infers values for another set of variables and generates a set of control signals based on the probabilistically inferred values.

A crop mass predictive sensor, comprising an imaging device, a laser-based device such as a LIDAR, a first radar emitting a frequency of energy that is absorbed by plant mass, and a second radar emitting a frequency of energy that passes through plant mass without being absorbed, wherein the imaging device, laser-based device, first radar, and second radar are focused on the crop material in front of an agricultural vehicle, and the information gathered from the imaging device, laser-based device, first radar, and second radar is used to calculate an estimated mass for the crop material that is about to enter the agricultural vehicle.

A combine side-shaking control system includes a sieve for separating crop material from other materials and a movable side-shaking mechanism coupled to the sieve and configured to move the sieve in a side-to-side motion. The control system also includes also includes first and second grain loss sensors configured to sense amounts of grain loss from separate portions of the sieve. The control system further includes a controller configured to: (i) receive a first grain loss value corresponding to the sensed first amount of grain loss and a second grain loss value corresponding to the sensed second amount of grain loss; and (ii) cause the side-shaking mechanism to control movement of the sieve in the side-to-side motion based on at least one of the received first grain loss value and the received second grain loss value.

A grain quality sensor comprising a lens, a filter, a photosite array, an illumination source, and an electronics module, wherein the illumination source directs light containing a known set of wavelengths onto a crop sample, wherein the lens picks up light reflected by the crop sample and directs it into the filter, which allows light to pass into different parts of the photosite array such that certain locations on the photosite array only get certain frequencies of the reflected light, wherein the electronics module is electrically connected to the photosite array and capable of determining which parts of the photosite array received light and what frequency the light received was, wherein the electronics module can analyze the optical data received by the photosite array, and wherein the analysis of the optical data is used to determine the composition of different parts of the crop sample.

A topographical indication for a field is detected by an aerial sensor and, based on the topographical indication, an area of consistent elevation is calculated. An estimated yield indication for a field is also detected, and an area of consistent estimated yield is calculated. With a controller, a calibration candidate zone is generated, wherein the calibration candidate zone comprises an area of the field with a consistent topography and a consistent estimated yield along a width and a length of the area.

A machine is controlled to operate according to a first control configuration. Enhancement criteria values, that are indicative of an enhancement metric, are evaluated based on operation in the first control configuration. The machine is then controlled to operate according to a second control configuration, and the enhancement criteria are again evaluated. The machine is iteratively switched between operating in the first and second control configurations until a signal-to-background-variation-ratio with respect to the evaluated enhancement criteria is sufficient. One of the first and second control configurations are then identified as corresponding to a best enhancement criteria value.
