Zusammenfassung:	To automatically control a nozzle position of a self-propelled vacuum device to more reliably suck up deposits.SOLUTION: A self-propelled vacuum device 10 is capable of rotating a vacuum nozzle 16 around a rotation shaft 24 (point A) provided on a vehicle body 12 using a power cylinder 20. A tilt angle sensor is provided to detect a tilt angle θ of the vehicle body 12. A target nozzle angle φref around the rotation shaft 24 (point A) is calculated based on the tilt angle θ and a target height yref of a tip of the nozzle 16. Rotation of the nozzle 16 around the rotation shaft 24 is feedback-controlled using the target nozzle angle φref as a target value.SELECTED DRAWING: Figure 1 【課題】自走式バキューム装置のノズル位置を自動制御して堆積物をより確実に吸引する。【解決手段】自走式バキューム装置１０は、パワーシリンダ２０を用いて車両本体１２に設けられた回転軸２４（Ａ点）周りにバキューム用のノズル１６を回動可能である。車両本体１２の傾斜角θを検出する傾斜角センサを設ける。傾斜角θとノズル１６の先端の目標高さｙrefとに基づき回転軸２４（Ａ点）周りの目標ノズル角度φrefを算出する。目標ノズル角度φrefを目標値として回転軸２４周りのノズル１６の回動をフィードバック制御する。【選択図】図１
