Automatic travel method, automatic travel program, and automatic travel system

A computer-readable non-volatile medium storing an automatic travel program that causes one or more processors to execute:

• causing a work vehicle to automatically travel along a target route in a work area;
• and
• determining, in a case where a detection part capable of detecting a detection target within a predetermined range detects the detection target, whether the detection target is an obstacle that obstructs travel of the work vehicle, based on a planned travel route on which the work vehicle is planned to travel from a time point at which the detection part detects the detection target.

An automatic travel system comprising:

• a travel processing part that causes a work vehicle to automatically travel along a target route in a work area;
• and
• a determination processing part that determines, in a case where a detection part capable of detecting a detection target within a predetermined range detects the detection target, whether the detection target is an obstacle that obstructs travel of the work vehicle, based on a planned travel route on which the work vehicle is planned to travel from a time point at which the detection part detects the detection target.
