To prevent splashing of a pedestrian when driving in a puddle.SOLUTION: A pedestrian notification device is comprised of: an imaging unit that images a front and a side of the own vehicle including a preceding vehicle of the own vehicle; a puddle detection unit that detects a puddle on a road surface based on an image captured by the imaging unit; a pedestrian detection unit that detects whether a pedestrian is within a predetermined range from the puddle based on the image when the puddle is detected, while the vehicle travels through the puddle; a traveling-related information acquisition unit that acquires traveling-related information including at least one of a traveling speed of the vehicle, tire information, and a depth of the puddle; a prediction unit that, when the pedestrian is detected, calculates a direction in which water in the puddle bounces, calculates a distance, and predicts whether or not the pedestrian will be flooded based on the travel-related information while the own vehicle runs through the puddle; and a notification control unit that notifies the pedestrian of the range in which the water in the puddle bounces when it is predicted that the water will be applied to the pedestrian.SELECTED DRAWING: Figure 1

    【課題】水溜りを走行する際に、歩行者などに対する水はねを防止すること。【解決手段】歩行者報知装置は、自車両の先行車を含む前方及び自車両の側方を撮像する撮像部と、撮像部が撮像した画像に基づいて、路面の水溜りを検出する水溜り検出部と、水溜りが検出された場合に、自車両が水溜りを走行する際に、水溜りから所定の範囲内に歩行者がいるか否かを画像に基づいて検出する歩行者検出部と、自車両の走行速度と、タイヤ情報と、水溜りの深さとの少なくとも一つを含む走行関連情報を取得する走行関連情報取得部と、歩行者が検出された場合に、水溜りの水が跳ねる方向と、距離とを算出し、自車両が水溜りを走行する際に、歩行者に水がかかるか否かを走行関連情報に基づいて予測する予測部と、歩行者に水がかかると予測された場合に、該歩行者に前記水溜りの水が跳ねる範囲を報知する報知制御部と、を備える。【選択図】図1
