To reduce troublesomeness and/or discomfort of a person who is unlikely to come in contact with a vehicle while inhibiting an object person who is likely to come in contact with a vehicle from coming in contact with a vehicle.SOLUTION: A vehicle warning system 1 includes cameras 101 and 102, a controller, and directional speakers 201a-e and 202a-e. The controller determines a relative position with an object vehicle as a reference using a camera video, determines a moving direction and a moving speed of the object using a plurality of camera videos with different imaging time points by the camera, determines a prediction position or a prediction region of the vehicle at each of future time points on the basis of a steering angle of a steering wheel and a speed of the vehicle, and determines whether or not the object is likely to come in contact with the vehicle using the prediction position or the prediction region of the vehicle at each of future time points, a relative position of the object, and the moving direction and the moving speed. When the object is likely to come in contact, the directional speakers are caused to dispatch a first sound in a direction according to the position of the object in the camera video.SELECTED DRAWING: Figure 1
【課題】車両に接触の可能性がある対象者が車両に接触するのを抑制しつつ、車両に接触の可能性がない人の煩わしさ及び/または不快感を低減する。【解決手段】車両警告システム1は、カメラ101、102と、コントローラと、指向性スピーカ201a〜e、202a〜eと、を備える。コントローラは、カメラ映像を用いて、対象物の車両を基準とする相対位置を決定し、カメラによる撮影時刻が異なる複数のカメラ映像を用いて、対象物の移動方向及び移動速度を決定し、車両のハンドルの舵角と速度に基づいて、未来の各時刻における車両の予測位置もしくは予測領域を決定し、未来の各時刻における車両の予測位置もしくは予測領域と、対象物の相対位置、移動方向及び移動速度とを用いて、対象物が車両に接触する可能性があるか否か判定する。接触する可能性がある場合、カメラ映像内の対象物の位置に応じた向きに指向性スピーカから第1の音を発信させる。【選択図】図1
