AUTONOMOUS TRAVEL SYSTEM, AUTONOMOUS TRAVEL METHOD, AND AUTONOMOUS TRAVEL PROGRAM

A farm field setting processing unit (212) sets an inner peripheral work region (F2) and an outer peripheral work region (F1) in a farm field (F) having a shape where a right side (F2b) and a left side (F2d) that face each other are not parallel to each other. A work-direction setting processing unit (214) sets a work direction for a work vehicle (10) within the inner peripheral work region (F2). A path setting processing unit (216) sets, within the inner peripheral work region (F2), a travel path (Rb1) as a work initiating path at a location adjacent to the right side (F2b) that is parallel to said work direction, from among a plurality of sides that define the inner peripheral work region (F2). On the basis of the work direction and the travel path (Rb1), a path generation processing unit (218) generates a travel path (Rb) for the work vehicle (10) within the inner peripheral work region (F2).
