Abstract: An automatic travel system for a work vehicle has an automatic travel control unit that causes a work vehicle, which is provided with an obstacle detection unit that detects obstacles, to travel automatically. The obstacle detection unit includes imaging units and active sensors. When the obstacle detection unit detects an obstacle based on information from the imaging units, and the separation distance from the obstacle is acquired based on information from the active sensors, the automatic travel control unit executes a first collision avoidance control for avoiding a collision between the work vehicle and the obstacle, on the basis of the separation distance from the obstacle acquired based on the information from the active sensors.

Abstract: The present invention is provided with a path generation unit that generates an operation path for each of a plurality of operation regions, and an automatic travel control unit that causes an operation vehicle to travel automatically along the operation path generated by the path generation unit. The path generation unit is configured to be able to generate a movement path that connects different operation regions by causing the operation vehicle to travel outside the operation regions. The automatic travel control unit is configured to temporarily stop the operation vehicle before switching the traveling path on which the operation vehicle travels automatically from a path inside the operation regions to a path outside the operation regions, and in response to the temporary stop state being terminated, cause the operation vehicle to travel automatically by switching the traveling path to a path outside the operation regions.
