Abstract: A detection processing unit detects an obstacle in the traveling direction of a work vehicle. A bypass setting processing unit sets a bypass starting position which is a starting position of a bypass route (Rse) for the work vehicle to travel while bypassing the obstacle detected by the detection processing unit, and a bypass end position which is an end position of the bypass route. When the detection processing unit detects the obstacle, a travel processing unit causes the work vehicle to travel on the bypass route.

Abstract: This work vehicle has: a positioning unit for measuring the current position and the current direction of the vehicle body using a satellite positioning system; and an automatic travel control unit for executing automatic travel control based on positioning information from the positioning unit. The positioning unit comprises: a plurality of positioning antennas provided on the vehicle body; a plurality of positioning units for measuring the positions of the positioning antennas; a calculation unit for calculating the current position and the current direction of the vehicle body on the basis of positioning information from the positioning units; and a positioning state determination unit for determining whether or not the positioning state of the positioning units is a high-accuracy positioning state. When at least two positioning units are in the high accuracy positioning state, the positioning state determination unit permits the start of the automatic travel control.

Abstract: This automatic travel system for a work vehicle is provided with: a position information obtaining unit; and an automatic travel control unit that causes a work vehicle to automatically travel along a target path. The automatic travel control unit sets a control target position on the target path including a plurality of work paths arranged in parallel with each other and a plurality of turning paths that connect the work paths in an order of travel of the work vehicle, to enable automatic travel of the work vehicle along the target path. The automatic travel control unit, when the work vehicle is positioned on a work path in the vicinity of a boundary with a turning path, sets the control target position on an extension of the work path. The automatic travel control unit, when the work vehicle is positioned on a turning path in the vicinity of a boundary with a work path, sets the control target position on the work path.

Abstract: This automated travel system for spraying work has a target path generation unit for generating a target path for a spraying work. A work vehicle is provided with left and right liquid spraying units which have spraying patterns including: a four-direction spraying pattern in which each of the left and right liquid spraying units sprays a liquid to both the left and right directions; and a direction-restricted spraying pattern in which the number of spraying directions of the left and right liquid spraying units is restricted to 3 or less. The target path generation unit generates the target path P in a path setting to incorporate a four-direction spraying path for which the four-direction spraying pattern is set as a spraying pattern and direction-restricted spraying paths for which the direction-restricted spraying pattern is set as a spraying pattern.

Abstract: This automated driving system for a work vehicle is provided with: an inertia measuring device that obtains tilt information of a work vehicle; and an automated driving control unit that causes the work vehicle to automatically travel along a target path. The work vehicle is provided with a work device that carries out a predetermined work with respect to a part to be worked on that is positioned away from the ground. The automated driving control unit calculates an offset amount on the basis of height information of a work center of the work device and the tilt information, and controls the location of the work vehicle with respect to the target path on the basis of the offset amount.
