To provide a fork lift configured so that an output state of a melody can be adjusted in accordance with presence of another work vehicle.SOLUTION: A fork lift comprises: an image data generating part 203; a learning model part 204 that generates a safety score using machine learning algorithm; a processing part 205 that obtains the safety score from the learning model part 204; a sound output part 201 that outputs a melody; a sound control part 208 that adjusts an output state of the melody; a position estimating part 206 that estimates a self-position; and an information obtaining part 207 that obtains a position of a vehicle with respect to a work vehicle 300A. The processing part 205 changes degrees of safety of the safety score, in accordance with a distance between the self-position and the position of the other vehicle, and outputs the safety score to the sound control part 208. The sound control part 208 adjusts the output state of the melody, on the basis of the safety score obtained from the processing part 205.SELECTED DRAWING: Figure 1

    【課題】別の作業車の存在に応じてメロディーの出力状態を調整可能なフォークリフトを提供する。【解決手段】画像データ生成部203と、機械学習アルゴリズムを用いて安全性スコアを生成する学習モデル部204と、学習モデル部204から安全性スコアを取得する処理部205と、メロディーを出力する音声出力部201と、メロディーの出力状態を調整する音声制御部208と、自己位置の推定を行う位置推定部206と、作業車300Aの他車位置を取得する情報取得部207とを備え、処理部205は、自己位置と他車位置との距離に応じて、安全性スコアの安全性の程度を変更して音声制御部208に出力し、音声制御部208は、処理部205から取得した安全性スコアに基づいて、メロディーの出力状態を調整することを特徴とする。【選択図】図1
