摘要： A work vehicle includes: an electronic control system for automatic driving; and a cabin with which a boarding space is formed. The electronic control system includes an antenna unit for satellite navigation, and the antenna unit is attached to a central area of a roof of the cabin in a left-right direction. An upper surface of an area of the roof around the antenna unit is formed so as to be an inclined surface that is inclined in a front-rear direction. Left and right end portions of the roof are provided with left and right bulging edge portions that bulge upward from the left and right end portions and have a length that spans between front and rear ends of the roof, and water drain grooves that guide water on the roof toward the left and right bulging edge portions such that water detours the antenna unit.

摘要： An obstacle detection device includes an ultrasonic sensor, an obstacle detector to determine presence of an obstacle of interest if an intensity of a received ultrasonic wave exceeds a threshold value, and a threshold value setter to set a short-distance detection threshold value as the threshold value for the obstacle detection in a short-distance detection area in a vicinity of the ultrasonic sensor and to set a long-distance threshold value as the threshold value for the obstacle detection in a long-distance detection area located farther from the ultrasonic sensor than the short-distance detection area, the long-distance threshold value being less than the short-distance detection threshold value. The short-distance detection area is an area where variation in sound pressure distribution of transmitted ultrasonic waves is equal to or greater than the threshold value, and the long-distance detection area includes an area where the variation of the sound pressure distribution of transmitted ultrasonic wave is smaller than the threshold value.

A work vehicle includes: a cabin 4 in which a boarding space is formed; and an electronic control system for automatic driving through which a vehicle body is automatically driven. The electronic control system includes a positioning unit that measures the position and orientation of the vehicle body, and a cooperation control unit that causes the vehicle body to automatically travel in cooperation with another vehicle. The cabin 4 is provided with a roof 62 that provides a storage space 62A that is surrounded by an inner roof 101 and an outer roof 102. The cooperation control unit includes a communication module 71 that wirelessly communicates with another vehicle to exchange information regarding cooperative travel with the other vehicle, including vehicle body position information. Antennas of the communication module 71 are provided on an upper end portion of the cabin 4, and a communication information processing apparatus 122 of the communication module 71 is provided in the storage space 62A.
