PATH GENERATION SYSTEM, AND AUTONOMOUS TRAVEL SYSTEM ENABLING WORK VEHICLE TO TRAVEL ALONG PATH GENERATED THEREWITH
Document Type and Number:
WIPO Patent Application WO/2018/139024
Kind Code:
A1
Abstract:
A work vehicle setting unit (36) of this path generation system (99) sets vehicle information of a tractor (1). An altitude information acquisition unit (56) acquires altitude information about an agricultural field in which an autonomous travel path is generated. A travel direction setting unit (57) sets the travel direction of the tractor (1) in the aforementioned agricultural field. A region setting unit (58) sets multiple regions, including a work region in which multiple autonomous work paths are generated parallel to the travel direction in the agricultural field, and a headland in which a connection path is generated connecting the aforementioned multiple autonomous work paths. On the basis of the vehicle information, the altitude information and the travel direction, the region setting unit (58) sets the width of the headland (the headland width) in the direction parallel to the direction of travel.
