A system and method are provided for work cycle tracking for a self-propelled work vehicle having an integrated or drawn/pushed implement, for example comprising a scraper, and a loading container for receiving material worked thereby. First sensors generate data corresponding to operating parameters of the work vehicle, and second sensors generate data corresponding to operating parameters of the implement. Data storage includes, for each of various work states associated with the work cycle, correlations between operating parameters, of the work vehicle and/or implement, and a start or completion of the respective work state. A controller determines a current work state of the various work states associated with the work cycle based on current input data from the first and second sets of sensors, with respect to the stored correlations, and generates one or more output signals based on the determined work state.

Work cycle identification for scrapers and corresponding feature automation

A system and method for controlling a vehicle platform, the system comprising on onboard controller and an off-board controller that work together to provide autonomous navigation in fields or similar areas where the vehicle is deployed, perception for obstacle detection and avoidance, and a user interface for user/vehicle interaction and control.

System and method of control for autonomous or remote-controlled vehicle platform

A system and method for controlling an implement connected to a vehicle is described, wherein the implement is adapted to perform an agricultural operation on a field, the vehicle has steerable ground engaging means for propelling the vehicle over the field, an actuator is arranged to control at least one of a yaw angle and a lateral position of the implement with respect to the vehicle, and an implement control unit is programmed to control the actuator based upon a first signal regarding a difference between a sensed lateral position of the implement and a nominal lateral position of the implement and a second signal regarding a steering movement of the vehicle.

System and method for controlling an implement connected to a vehicle

An agricultural vehicle comprises a left frame and a right frame. A left wheel is rotatable with respect to the left frame and a right wheel is rotatable with respect to the right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. A data processor estimates a reference point on or below the vehicle and an angular orientation or attitude of the beam relative to the reference point based on positions of location-determining receivers associated with the beam. An upper carriage is laterally movable along the beam. A lower carriage is suspended from the upper carriage by a plurality of vertical supports, such that a target lateral position of the upper carriage establishes an actual lateral position of the lower carriage.

Agricultural vehicle with adjustable row unit

A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. One or more row units are suspended from the beam, each row unit having a first nozzle and a second nozzle, wherein the first nozzle and the second nozzle are associated with an adjustable reference position in one or more dimensions with respect to the beam.

Adjustable row unit and vehicle with adjustable row unit

A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. One or more row units are suspended from the beam, such that the position of nozzle or nozzles on each row unit can be adjusted simultaneously and dynamically in multiple dimensions to maintain a target spacing between the nozzle and ground and the nozzle and a plant or row of plants.

Adjustable row unit and sprayer vehicle with adjustable row unit

In accordance with one embodiment, a row unit for an agricultural vehicle comprises an upper carriage that is movable or slidable with respect to a generally horizontal beam of the vehicle. The row unit has vertical supports, where each vertical support has an upper end connected to the upper carriage and a lower end opposite the upper end. The row unit further comprises a lower carriage that is connected to the lower end of the vertical supports, such that the upper carriage determines a lateral position of the lower carriage with respect to the beam.

Various embodiments of the present disclosure provide a guided line acquisition system and method for generating a path of a vehicle from its current location to a final guidance line. This path is referred to hereinafter as an acquisition path. The generated acquisition path starts at the current vehicle position and ends co-linear to the final guidance path. The acquisition path is generated using one constraint and one objective parameter. More specifically, the acquisition path is constrained by the minimum turning radius of the vehicle and angle of approach criteria, (i.e., the maximum heading relative to the guidance line). It should be appreciated that while the guided line acquisition system attempts to find an acquisition path that meets the angle of approach criteria, the guidance acquisition system will allow this objective to be sacrificed when it is not possible due to the minimum turning radius of the vehicle.

System and method for guided line acquisitions

An agricultural vehicle comprises a left frame and a right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. In on configuration, at least one row unit suspended from the beam, where each row unit has a respective planting device with an adjustable position in one or more dimensions with respect to the beam for precise application or variable application of seeds within the rows or field.

In an example embodiment, a vehicle guidance system includes a memory including computer-readable instructions stored therein and a processor. The processor is configured to execute the computer-readable instructions to estimate a wheel angle of a vehicle based on at least a first value, the first value being a hand wheel based estimate of the wheel angle, and adjust steering commands for steering the vehicle based on the estimated wheel angle to permit the vehicle to move along a set path.

Methods and apparatuses for determining estimates of a vehicle's wheel angle and the vehicle's steering ratio

A first sensor is associated with the first arm to provide a first sensor signal response indicative of a first position or first movement of the first arm with respect to the first row. A second sensor is associated with the second arm to provide a second sensor signal response indicative of a second position or second movement of the second arm with respect to the first row, or second row. A data processor is adapted to estimate a center point of the first row or a center point between the first row and the first row, or second row based on targeting substantial symmetry in the first sensor signal response and the second sensor signal response as an indication that a longitudinal axis of the vehicle is aligned with the center point, for example.
