To provide an illuminance estimation device which can improve estimation accuracy of illuminance.SOLUTION: An illuminance estimation device 100 comprises: cameras 101-110; a navigation system 112 or communication module 113; and an electronic control unit 115. The cameras 101-110 are mounted on an own vehicle 111 and image a region which is directly or indirectly irradiated with light of the sun 200. The navigation system 112 or the communication module 113 acquires vehicle information including at least the current position of the own vehicle 111, the current orientation of the own vehicle 111 and the current date and time. The electronic control unit 115 acquires images from the cameras 101-110 and acquires the vehicle information from the navigation system 112 or the communication module 113. The electronic control unit 115 estimates the current position of the sun 200 and illuminance around the own vehicle 111 on the basis of the images and the vehicle information.SELECTED DRAWING: Figure 1

    【課題】照度の推定の精度を向上させることができる照度推定装置を提供する。【解決手段】照度推定装置100は、カメラ101~110、ナビゲーションシステム112または通信モジュール113、及び電子制御ユニット115を含む。カメラ101~110は、自車111に搭載されると共に、太陽200の光が直接的あるいは間接的に照らされる領域を撮影する。ナビゲーションシステム112または通信モジュール113は、少なくとも自車111の現在の位置、自車111の現在の向き、及び現在の日時を含む車両情報を取得する。電子制御ユニット115は、カメラ101~110から画像を取得すると共に、ナビゲーションシステム112または通信モジュール113から車両情報を取得する。電子制御ユニット115は、画像及び車両情報に基づいて、現在の太陽200の位置及び自車111の周囲の照度を推定する。【選択図】図1
