To provide a rainfall amount measurement device that is mounted on a vehicle and can provide a general measured value of a rainfall amount with simpler device configuration.SOLUTION: A rainfall amount measurement device (100) comprises an information acquisition part (101), a calculation part (103), and an output part (104). The information acquisition part acquires, based upon output of a detection part (65) which generates the output corresponding to the sticking amount of rain drops (D) on an outer wall surface (2a) of the windshield (2) of a vehicle, rain drop amount information to be used to set wiping intervals of wipers (3) for wiping rain drops sticking on the outer wall surface and corresponding to a sticking amount within a measurement period. The calculation part calculates, based upon the rain drop amount information acquired by the information acquisition part, a measured value of a rainfall amount per unit time. The output part outputs the measured value calculated by the calculation part to a communication part (9) which communicates the outside (X) of the vehicle.SELECTED DRAWING: Figure 3

    【課題】車両に搭載される降雨量計測装置において、汎用性のある降雨量の計測値をより簡略な装置構成により提供可能とすること。【解決手段】降雨量計測装置(100)は、情報取得部(101)と、算出部(103)と、出力部(104)とを備えている。情報取得部は、車両のウインドシールド(2)における外壁面(2a)に対する雨滴(D)の付着量に対応する出力を発生する検知部(65)の出力に基づいて、外壁面に付着した雨滴を払拭するワイパ(3)における払拭間隔の設定に用いられる、計測期間内の付着量に対応する雨滴量情報を取得する。算出部は、情報取得部により取得された雨滴量情報に基づいて、単位時間当たりの降雨量の計測値を算出する。出力部は、算出部により算出された計測値を、車両外部(X)との通信を行う通信部(9)に出力する。【選択図】図3
