PROBLEM TO BE SOLVED: To provide a work vehicle autonomous travel system that can safely stop a work vehicle even when the remote control becomes impossible.SOLUTION: A work vehicle autonomous travel system has: a first communication device for remote control 71 that performs operation control of a work vehicle 1 by communication with the work vehicle 1； and a second communication device for remote control 70 that performs setting of a travel route and operation control of the work vehicle 1 by communication with the work vehicle 1. When communication is established with both of the first and second communication devices for remote control 71,70, the work vehicle 1 is permitted to perform autonomous travelling.SELECTED DRAWING: Figure 18COPYRIGHT: (C)2019,JPO&INPIT【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
