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

Provided are an automatic travel method, an automatic travel system, and an automatic travel program with which it is possible to improve work efficiency in a work vehicle provided with a work machine. A route generation processing unit (214) generates a target route (R) that includes a plurality of straight routes (R1) and that causes a work vehicle (10) to automatically travel from a start position to an end position of each straight route (R1). The reception processing unit (215) receives a first setting operation that is set so that the work vehicle (10) travels backward toward the start end position of the first straight path (R1) after reaching the end position of the first straight path (R1), or a second setting operation that is set so that the work vehicle (10) travels forward to the second straight path (R1) after reaching the end position of the first straight path (R1). 本发明提供能够使具备作业机的作业车辆中的作业效率提升的自动行驶方法、自动行驶系统以及自动行驶程序。路径生成处理部(214)生成包括多个直行路径(R1)在内的、使作业车辆(10)从各直行路径(R1)的始端位置自动行驶到终端位置的目标路径(R)。受理处理部(21
