Guidance method for agricultural vehicle

摘要

An automated method and system includes an automatic guidance system (AGS) (24) and swath pattern (18). The AGS (24) steers a vehicle (11) towing a rotary baler (10) in an "S", or oscillatory pattern (30) around a predetermined approximate centerline (12) of the swath path. The oscillatory pattern (30) may be user defined. By steering the vehicle (11) in an oscillatory pattern referenced to the A-B line, a windrow (18) of crop material (16) may be distributed into an even and optimal bale size and density by the baler (10). Bale chamber sensors (45) detect an imbalance of crop density and in response, AGS (24) adjusts an interval or amplitude of oscillatory pattern.
