Autonomous traveling system for working vehicle to travel autonomously

An autonomous travel system comprising:

• a route creation unit that creates a plurality of linear routes arrayed in a farm field;
• a forward movement control unit that autonomously implements at least steerage to cause a working vehicle to travel along the plurality of linear routes while causing the working vehicle to conduct a work;
• a backward movement control unit that causes the working vehicle to move backward opposite to a forward linear direction either according to an operation by an operator or autonomously, without causing the working vehicle to conduct the work, after the operator stops the working vehicle traveling toward an edge of the farm field along the plurality of linear routes by the forward movement control unit;
• and
• a turning control unit that autonomously implements at least the steerage to cause the working vehicle to turn along a turning path connected to a linear route designated in advance without causing the working vehicle to conduct the work and without moving in a linearly forward direction between an end of backward movement and a start of turning, on condition that a forward movement instruction is given by the operator after the working vehicle, which is being caused to move backward by the backward movement control unit, is stopped either by the operator or autonomously,
• wherein the backward movement control unit autonomously implements at least the steerage to cause the working vehicle to move backward along the linear route designated in advance without causing the working vehicle to conduct the work.
