To provide an industrial vehicle capable of preventing a person from falling due to being surprised by notification sound.SOLUTION: An industrial vehicle 1 includes a speaker that outputs notification sound to a person H, a learned model including a sound volume estimation unit, and a sound volume change unit. The sound volume estimation unit performs machine learning in advance using training data using a notification distance from the speaker to the person H and a sound volume of the notification sound as input data and a degree of surprise of the notified person as output data. When the sound volume estimation unit receives an input of the notification distance, the sound volume estimation unit estimates a sound volume with which the degree of surprise of the notified person becomes equal to or less than a predetermined degree of surprise. The sound volume change unit changes a sound volume of the speaker to equal to or less than the estimated sound volume.SELECTED DRAWING: Figure 1
【課題】報知音に驚いて人が転倒することを防止することができる産業車両を提供する。【解決手段】産業車両1は、人Hに報知音を出力するスピーカと、音量推定部を有する学習済みモデルと、音量変更部と、を備えている。音量推定部は、スピーカから人Hまでの報知距離と報知音の音量とを入力データとし報知された人の驚き度を出力データとする教師データによってあらかじめ機械学習し、報知距離を入力されると、報知された人が所定の驚き度以下になる音量を推定する。音量変更部は、推定された音量以下にスピーカの音量を変更する。【選択図】図1
