Satellite Based Vehicle Guidance Control In Straight And Contour Modes
US Patent:
8190337, May 29, 2012
Filed:
Oct 14, 2008
Appl. No.:
12/251279
Inventors:
John A. McClure - Scottsdale AZ, US
Dennis M. Collins - Overgaard AZ, US

Assignee:
Hemisphere GPS, LLC - Calgary, Alberta
International Classification:
G06F 7/70
US Classification:
701 50, 701 23, 701221, 701213
Abstract:
A method for steering an agricultural vehicle comprising: receiving global positioning system (GPS) data including position and velocity information corresponding to at least one of a position, velocity, and course of the vehicle; receiving a yaw rate signal; and computing a compensated heading, the compensated heading comprising a blend of the yaw rate signal with heading information based on the GPS data. For each desired swath comprising a plurality of desired positions and desired headings, the method also comprises: computing an actual track and a cross track error from the desired swath based on the compensated heading and the position; calculating a desired radius of curvature to arrive at the desired track with a desired heading; and generating a steering command based on the desired radius of curvature to a steering mechanism, the steering mechanism configured to direct the vehicle.
Raster-Based Contour Swathing For Guidance And Variable-Rage Chemical Application
US Patent:
2013017, Jul 11, 2013
Filed:
Feb 25, 2013
Appl. No.:
13/776512
Inventors:
John A. McClure - Scottsdale AZ, US
Dennis M. Collins - Overgaard AZ, US
Dennis M. Collins - Overgaard AZ, US
International Classification:
A01B 69/04
US Classification:
701 25
Abstract:
A raster-based system for GNSS guidance includes a vehicle-mounted GNSS antenna and receiver. A processor provides guidance and/or autosteering commands based on GNSS-defined pixels forming a grid representing an area to be treated, such as a field. Specific guidance and chemical application methods are provided based on the pixel-defined treatment areas and preprogrammed chemical application prescription maps, which can include variable chemical application rates and dynamic control of the individual nozzles of a sprayer.
