Patent application number | Description | Published |
20100324772 | Automatic Control of Passive, Towed Implements - An automatic control system for passive, towed implements is described. The system provides a strategy for optimal control of a towed implement using a nudge input to an autopilot-controlled tractor. Implement path-tracking error, as measured by a GNSS receiver, is consistently corrected to zero. | 12-23-2010 |
20120296529 | Agricultural Autopilot Path Adjustment - Predictive tractor path adjustments improve implement tracking performance by enabling agricultural autopilots to anticipate the effect of curves, slopes, changing soil conditions and other influences. | 11-22-2012 |
20130289833 | Agricultural Autopilot Path Adjustment - Predictive tractor path adjustments improve implement tracking performance by enabling agricultural autopilots to anticipate the effect of curves, slopes, changing soil conditions and other influences. | 10-31-2013 |
20130304300 | Path planning autopilot - A path planning autopilot guides vehicles efficiently even when they are far from a desired path. | 11-14-2013 |
20140074340 | Agricultural autopilot steering compensation - Agricultural autopilot steering compensation provides improved steering control when steerable wheels lose traction and/or in tight turns. | 03-13-2014 |
20140168009 | Multi-IMU INS for vehicle control - Multi-IMU INS for vehicle control allows GNSS-derived position and velocity to be measured at an antenna and applied to the estimation of position, velocity and attitude at a separate control point even when the spatial relationship between antenna and control point is not constant. | 06-19-2014 |
20150198953 | Path planning autopilot - A path planning autopilot guides vehicles efficiently even when they are far from a desired path. | 07-16-2015 |
20150342110 | Implement guidance - Efficient towed implement guidance to a desired path is achieved by guiding a towing vehicle toward a path on the opposite side of a desired path, then guiding the vehicle back to the desired path. Efficient forward implement guidance to a desired path is achieved by guiding a pushing vehicle along a tractrix. A vehicle leaves a straight line along a tractrix to keep a rear implement on the line as long as possible. | 12-03-2015 |
