To address recognition of an obstacle or object around an own vehicle, and real-time detection and position identification of a sound source.SOLUTION: Audio data is received from plural audio sensors installed in an autonomous vehicle (ADV). The audio data contains sounds fetched into the audio sensors and released from one or more sound sources. In the present method, plural pieces of sound source information are determined based on the received audio data. Each sound source information contains a reliability score relating to existence of a specific sound. In the present method, a data representation for use in reporting whether the specific sound exists in a driving environment of the ADV is produced. The data representation contains the determined pieces of sound source information. The received audio data and produced data representation are used to subsequently drill a mechanical learning algorithm, and the specific sound source is recognized in real-time during autonomous driving of the ADV.SELECTED DRAWING: Figure 7

    【課題】自車の周囲の障害物又は物体の認知を、音源のリアルタイムの検出と位置特定に関する。【解決手段】自律運転車両(ADV)に取り付けられた複数のオーディオセンサからオーディオデータを受信する。オーディオデータは、オーディオセンサによって取り込まれて1つ以上の音源から放出された音を含む。本方法では更に、受信したオーディオデータに基づいて、複数の音源情報を決定する。各音源情報は、特定の音の存在に関連する信頼スコアを含む。本方法では更に、ADVの運転環境内に特定の音が存在するか否かを報告するためのデータ表現を生成する。データ表現は、決定された音源情報を含む。受信したオーディオデータ及び生成されたデータ表現を使用して機械学習アルゴリズムを続いて訓練し、ADVの自律運転中に特定の音源をリアルタイムで認識する。【選択図】図7
