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: To make it easier for an operator to notice an object in the surroundings of a construction machine. A safety monitoring system includes a detection device, a display unit, and a control unit. The detection device detects an object in the surroundings of the work vehicle. The display unit displays a captured image of the surroundings of the work vehicle. The control unit controls the detection device and the display unit. If the detection device detects an object, the control unit controls the display unit to display an image with a defined edge obtained by applying an edge-defining process to the image of the surroundings.

Abstract: An engine including an exhaust bypass valve and an intake bypass valve. The exhaust bypass valve is disposed in an exhaust bypass channel connecting an outlet of an exhaust manifold and an exhaust outlet of a turbocharger to each other. The intake bypass valve is disposed in an intake bypass channel connecting an inlet of an intake manifold and an inlet of the turbocharger. An intake pressure sensor detects a pressure of the intake manifold. If an instruction value indicating an upper limit or a lower limit of the valve opening degree of the intake bypass valve is continuously output for a predetermined time or more, an engine control device determines that an abnormality occurs in at least one of the exhaust bypass valve and the intake bypass valve.

Abstract: An engine includes: an exhaust manifold 7 close to one of left and right side surfaces of an engine; a turbocharger 60 having an exhaust-side inlet connected to the exhaust manifold 7; and a rocker-arm-chamber-integrated intake manifold 8 being disposed on an upper surface of a cylinder head 5 and integrally including a rocker arm chamber 90 and an intake manifold 6. The intake manifold 8 has a wall 101 dividing the rocker arm chamber 90 close to the one of the left and right side surfaces of the engine 1 and the intake manifold 6 close to the other of the left and right side surfaces to isolate the rocker arm chamber 90 and the intake manifold 6 from each other. The rocker arm chamber 90 has, in its upper portion, a positive crankcase ventilation device 69 protruding therefrom and being configured to return blowby gas to an intake system. The positive crankcase ventilation device 69 has, in its side surface, a blowby-gas discharge port 67 connected with a gas conduit 68 through which blowby gas is delivered to an intake-side inlet of the turbocharger 60.

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.

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.
