To provide a technology for efficiently operating a control system and an operation system brake in an autonomous travel vehicle, according to an operation state of the autonomous travel vehicle.SOLUTION: A high-pressure selection valve is provided in a passage that supplies pressure oil to a hydraulic brake device from a standard-machine brake valve mounted in a standard machine, and a passage connecting the high-pressure selection valve and an autonomous brake control valve supplied with pressure oil discharged from a hydraulic pump is also provided. In addition, the work machine comprises: an autonomous travel control device that exerts control for autonomous travel; and an autonomous brake control device that exerts opening/closing control for the autonomous brake control valve in response to a brake command from the autonomous travel control device. By depressing a brake pedal, pressure oil flows from the standard-machine brake valve to the hydraulic brake device. When the autonomous travel control device outputs a stop command, pressure oil flows in the hydraulic brake device from the autonomous brake control valve, and a brake operation is carried out.SELECTED DRAWING: Figure 1

    【課題】自律走行車両における制御系及び操作系ブレーキを自律走行車両の動作状況に応じて効率的に動作させる技術を提供する。【解決手段】標準機に搭載された標準機ブレーキバルブから油圧ブレーキ装置に圧油を供給する流路上に高圧選択弁を設け、油圧ポンプから吐出された圧油が供給される自律ブレーキ制御バルブと高圧選択弁とを接続する流路を設ける。更に、自律走行させるための制御を実行する自律走行制御装置、及び自律走行制御装置からの制動指令に応じて自律ブレーキ制御バルブの開閉制御を行う自律ブレーキ制御装置を備える。ブレーキペダルを踏むと標準機ブレーキバルブから油圧ブレーキ装置に圧油が流れ、自律走行制御装置が停止指令を出力すると自律ブレーキ制御バルブから油圧ブレーキ装置に圧油が流れて制動動作が実行される。【選択図】図1
