Problem to be solved: to provide an autonomous running system for a work vehicle capable of safely stopping a work vehicle even when it is impossible to operate remotely.The autonomous traveling system of the working vehicle comprises a first remote control communication apparatus 71 for controlling the operation of the working vehicle 1 by communication with the working vehicle 1, and a second remote control communication device 70 for setting the travel path and controlling the operation of the working vehicle by communication with the working vehicle 1.The working vehicle 1 is allowed to autonomously run when communication with both the first and second telemetry units 71 and 70 is established.Diagram【課題】遠隔操作不能となった場合であっても作業車両を安全に停止できる作業車両の自律走行システムを提供する。【解決手段】作業車両の自律走行システムは、作業車両１との通信により作業車両１の動作制御を行う第１遠隔操作用通信装置７１と、作業車両１との通信により走行経路の設定及び作業車両の動作制御を行う第２遠隔操作用通信装置７０とを備える。作業車両１は、第１及び第２遠隔操作用通信装置７１，７０双方との通信が確立されたときに、自律走行が許可される。【選択図】図１８
