DEVICE AND METHOD FOR SETTING TURNING START POSITION OF AGRICULTURAL WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To automatically and reliably set a turning start point at which an agricultural working vehicle can reliably turn in a headland.

SOLUTION: The device for setting the turning start position of an agricultural working vehicle includes: an original point setting part 1 for setting an original part P as a travel starting point of the agricultural working vehicle 100 based on position information of GPS; a reference line setting part 3 for setting a linear reference line L1 from the original point P; a moved distance measuring part 4 for measuring a moved distance from the original point P; a travel distance measuring part 5 for measuring an actual travel distance of the agricultural working vehicle 100; a distance difference calculating part 6 for calculating the difference between the measured moved distance and the travel distance; a turning determination part 7 for determining that the agricultural working vehicle 100 turns; a turning determination point setting part 8 for setting a turning determination point P2 at a position where turning of the agricultural working vehicle 100 is determined; a linear reference point setting part 9 for setting a linear reference point P3 at an any point on the reference line L1; and a turning start position setting part 10 for setting a final position as a turning start position P4 by returning back from the turning determination point P2 to the reference line L1 and detecting the final point without having the distance difference on the reference line L1.
