TRAVEL ROUTE SETTING DEVICE OF FIELD WORK VEHICLE, FIELD WORK VEHICLE, TRAVEL ROUTE SETTING METHOD OF FIELD WORK VEHICLE AND PROGRAM FOR SETTING TRAVEL ROUTE

摘要

To set a travel route that enables an entire field surface to travel without making useless travel in a field of a shape being not rectangular, without damaging the already-worked progression path, and without travel of unreasonable turning and cutback.SOLUTION: In reciprocation areas RTA1, RT2, a first reciprocation route RR1 of going straight along one side SD4 of a field FD after starting travel at the endpoint S1 and performing the reciprocating travel while turning toward the other side SD2 is set. Also, a second reciprocation route RR2 is set that is the reciprocation route going straight along the other side SD2, turned toward the one side SD4 in a first direct terminal LE1, and is made to turn toward the other side SD2 in the direct end point after that. Further, in an outer circumference area OCA, an outer circumference route OR is set that continues travel from the terminal of the second reciprocation route RR2 and travels along the outer circumference area OCA.SELECTED DRAWING: Figure 6
