To provide a remote control system that allows an operator to operate a work vehicle during autonomous driving without delay at the time of emergency.SOLUTION: A remote control system includes: a work vehicle 1 including a vehicle driving control unit for controlling autonomous driving of a vehicle body 2, an imaging unit for outputting image data, and a vehicle side communication unit; a radio communication terminal device 70 including instruction signal creation means for creating a driving control instruction signal according to manual operation; a terminal side communication unit for transmitting the driving control instruction signal to the vehicle side communication unit by a first radio communication method, and receiving the image data, and a display unit for displaying the image data; and a stop remote control 72 including stop instruction operation means for creating a stop instruction signal by manual operation and a remote control side communication unit for transmitting the stop instruction signal to the vehicle side communication unit by a second radio communication method with smaller data transmission amount than the first radio communication method. The vehicle driving control unit controls autonomous driving of the vehicle body 2 according to the driving control instruction signal and stops the vehicle body 2 according to the stop instruction signal.SELECTED DRAWING: Figure 1 【課題】自律走行中の作業車両に対してオペレータが緊急時に遅滞なく操作できる遠隔制御システムを提供する。【解決手段】遠隔制御システムは、機体２の自律走行を制御する車両走行制御部と、画像データを出力する撮像部と、車両側通信部とを備える作業車両１と、手動操作に応じて走行制御指示信号を作成する指示信号作成手段と、第１無線通信方式により車両側通信部に走行制御指示信号を送信し画像データを受信する端末側通信部と、画像データを表示する表示部とを備える無線通信端末装置７０と、手動操作により停止指示信号を作成する停止指示操作手段と、車両側通信部に対して、第１無線通信方式よりもデータ伝送量が小さい第２無線通信方式で停止指示信号を送信するリモコン側通信部とを備える停止用リモコン７２とを備える。車両走行制御部は、走行制御指示信号に応じて機体２の自律走行を制御し、停止指示信号に応じて機体２を停止させる。【選択図】図１
