To suppress noise to a peripheral environment and a vehicle interior of a vehicle, and notify a pedestrian of approach of a vehicle.SOLUTION: Cameras 12L, 12LH, 12RH, 12R capture a visual field in the surrounding of a vehicle. Front speakers 16Lw, 16Ln, 16Rw, 16Rn, rear speakers 18w, 18n, left speakers 20Lw, 20Ln, right speakers 20Rw, 20Rn generate approach notification sound to the surrounding of the vehicle. A control circuit 14 searches a pedestrian based on outputs from the cameras 12F,12LH,12RH, 12R, and as a number of detected pedestrians is smaller, the control circuit makes directivity of the approach notification sound stronger.SELECTED DRAWING: Figure 1
【課題】車両の周辺環境や車室内に対する騒音を抑制しつつ、歩行者に車両の接近を通報すること。【解決手段】カメラ12L,12LH,12RH,12Rは、車両の周囲の視界を捉える。また、前スピーカ16Lw,16Ln,16Rw,16Rn,後スピーカ18w,18n,左スピーカ20Lw,20Ln,右スピーカ20Rw,20Rnは、車両の周囲に向けて接近通報音を発生する。制御回路14は、カメラ12F,12LH,12RHおよび12Rからの出力に基づいて歩行者を探索し、探知された歩行者の数が少ないほど接近通報音の指向性を強くする。【選択図】図1
