AUTONOMOUS DRIVING METHOD, COMBINE, AND AUTONOMOUS DRIVING SYSTEM

[Problem] To provide an autonomous driving method, a combine, and an autonomous driving system that make it possible to reduce the burden on an operator and improve work efficiency by properly performing automatic discharge travel after completing automatic harvesting travel. [Solution] A combine harvester 1 comprises a control device 50. The control device 50 functions as a travel route creation unit 61, a discharge route creation unit 62, and an autonomous driving control unit 64. The travel route creation unit 61 creates a travel route R for an unharvested area of a field. The discharge route creation unit 62 creates a discharge route D that extends from an end position E, of the travel route R, at which automatic harvesting of the unharvested area is completed, to a discharge position which is preset for the field. The autonomous driving control unit 64 controls the automatic harvesting travel according to the travel route R or the automatic discharge travel according to the discharge route D.
