Abstract: Techniques for multi-modal contextualization of object detection for use with an agricultural vehicle are described herein. The techniques can provide additional context information to radar detection to assess the likelihood of an object detected by radar of being an object of interest. Examples of detection that might be detected by a radar sensor that, based on the additional context information, the agricultural vehicle can make a determination to ignore can include ground targets, ghost targets, side or overhead reflections from obstacles, detections from tall crops/weeds in a field.

Abstract: A control system includes a first input to receive a positional output characteristic of a first vehicle at a first communication frequency and a second input to receive a kinematic output characteristic of the first vehicle at a second frequency, where the second frequency is greater than the first frequency. A guidance controller of a second vehicle is configured to process the kinematic output characteristic of the first vehicle to obtain a heading of the first vehicle, compare the heading of the first vehicle with a heading of the second vehicle to obtain a heading deviation of the second vehicle, and determine a guidance heading of the second vehicle based on the heading deviation of the second vehicle. A control interface is configured to communicate the guidance heading to one or more of steering, throttle or brake elements of the second vehicle.

Abstract: An autonomous vehicle control system includes one or more sensors configured for coupling with an agricultural vehicle, the one or more sensors configured to determine kinematics of the agricultural vehicle relative to a crop row. The system includes a guidance control module configured to coordinate steering of one or more steering mechanisms of the agricultural vehicle. The guidance control module includes a sensor input configured to receive kinematics of the agricultural vehicle, a vehicle kinematics comparator configured to determine one or more error values using the received vehicle kinematics, a crop curvature generator configured to determine crop row curvature using the one or more error values, and a steering interface configured to provide instructions to a vehicle steering controller to guide the agricultural vehicle using the crop row curvature.

Abstract: A system having a guidance module to obtain a travel path from an agricultural machine to a target. The guidance module including a perception module to determine target line that extends from the machine to the target, and obstacle detection module to detect an obstacle in the first target line, the obstacle having an obstacle boundary that intersects the target line. The guidance module including a mitigation module to obtain a mitigation path around the obstacle based on the target line and the obstacle boundary, the mitigation path including a mitigation segment. The mitigation module including an entrance module configured to determine a starting position of the mitigation path based on a second target line and an exit module configured to determine the ending position of the mitigation path based on a third target line. The guidance module including convergence module to combine the mitigation path with the travel path.

Abstract: A guidance assembly for an agricultural vehicle includes a pathing system configured to provide an array of swaths. The guidance assembly includes a composite guidance system in communication with an automated driving interface and the pathing system. The composite guidance system includes a turn guidance system configured to guide the agricultural vehicle along at least one turn segment extending between a first zone swath and a transverse second zone swath, and a swath guidance system configured to guide the agricultural vehicle along the first zone swath and the transverse second zone swath. The system includes a comparator configured to compare the agricultural vehicle position with swath departure and arrival locations. An interswath turning element automatically toggles the turn and swath guidance systems between activated and paused configurations according to the compared agricultural vehicle position and the swath departure and arrival locations.
