To provide an automatic traveling system for a travel vehicle that performs a traveling test on an unmanned driving vehicle.SOLUTION: In an automatic traveling system 10 for a travel vehicle to circulate and travel an unmanned driving vehicle 20 by traveling the unmanned driving vehicle 20 by a driving control part along a circuit course 11 provided with a curved road with a bank. Signs which are rough indications of traveling positions are provided along the circuit course 11, and the unmanned driving vehicle 20 comprises: a travel part and a steering part for traveling on a track; and a detection part for detecting a traveling state on the track. An obstacle sensor is provided in a blind point which is hardly visually recognized on the circuit course 11, and a driving control part detects the position, vehicle speed and posture of the unmanned driving vehicle 20, and a sign on the basis of a detection signal from the detection part of the unmanned driving vehicle 20, and also by recognizing an object in the blind point on the basis of the detection signal of the obstacle sensor, and drives and controls the travel part and the steering part so as not to come into contact with the object during traveling.SELECTED DRAWING: Figure 1
【課題】無人運転車両の走行テストを行う走行車両の自動走行システムの提供。【解決手段】バンク付き曲線路を備えた周回コース11に沿って、運転制御部により無人運転車両20を走行させて無人運転車両20の周回走行を行う走行車両の自動走行システム10であって、周回コース11に沿って走行位置の目安となる標識が設けられ、無人運転車両20が、走行路を走行するための走行部及び操舵部と、走行路における走行状態を検出する検出部と、を備え、周回コース11の視認しにくい見通しの悪い箇所に、障害物センサを備え、運転制御部が、無人運転車両20の検出部からの検出信号に基づいて、無人運転車両20の位置,車速及び姿勢と、標識を検出して、また障害物センサの検出信号に基づいて、見通しの悪い箇所内の物体を認識して、走行中に物体と接触しないよう走行部及び操舵部を駆動制御する。【選択図】図1
