PROBLEM TO BE SOLVED: To provide a work vehicle autonomous travel system capable of direct advance along a planned route even if communication with a positioning satellite is poor in work vehicles that travel autonomously.SOLUTION: A work vehicle receives a positioning signal 31 transmitted by a positioning satellite 30 to obtain positioning information and performs work while autonomously travelling along a predetermined planned travel path R on the basis of the positioning information. The work vehicle is equipped with a camera 14 for photographing a scenery in front of the vehicle 1, and performs steering control on the basis of a photographic image by the camera 14 depending on a reception situation of the positioning signal 31 transmitted by the positioning satellite 30.SELECTED DRAWING: Figure 4

    【課題】自律走行する作業車両において、測位衛星との通信が良好でない場合でも、予定経路に沿って直進可能な作業車両の自律走行システムを提供する。【解決策】測位衛星30から送信される測位信号31を受信して測位情報を取得し、測位情報に基づいて予め定められた予定走行経路Rに沿って自律走行しながら作業を行う作業車両において、車両1の前方を撮影するカメラ14を搭載し、前記測位衛星30から送信される測位信号31の受信状況に応じて、前記カメラ14の撮影画像に基づいた操向制御を行う。【選択図】図4
