Abstract
(EN)
A power supply control apparatus (100) is provided with: a temperature information acquisition unit (21) which acquires temperature information indicating a temperature (Temp) in a vehicle-mounted information device (300); a dark current estimation unit (22) which uses the temperature information to estimate a dark current (I) in the vehicle-mounted information device (300) on the basis of the temperature (Temp); and a power supply control unit (25) which performs control to set a power supply circuit (16) of the vehicle-mounted information device (300) to an off state depending on the result of the estimation performed by the dark current estimation unit (22).
(FR)
L'invention concerne un appareil de commande d'alimentation électrique (100) qui comprend : une unité d'acquisition d'informations de température (21) qui acquiert des informations de température indiquant une température (Temp) dans un dispositif d'information embarqué (300) ; une unité d'estimation de courant d'obscurité (22) qui utilise les informations de température pour estimer un courant d'obscurité (I) dans le dispositif d'information embarqué (300) sur la base de la température (Temp) ; et une unité de commande d'alimentation électrique (25) qui effectue une commande pour régler un circuit d'alimentation électrique (16) du dispositif d'informations embarqué (300) à un état éteint en fonction du résultat de l'estimation effectuée par l'unité d'estimation de courant d'obscurité (22).
(JA)
電源制御装置(100)は、車載用情報機器(300)における温度(Temp)を示す温度情報を取得する温度情報取得部(21)と、温度情報を用いて、温度(Temp)に基づき、車載用情報機器(300)における暗電流(I)を推定する暗電流推定部(22)と、暗電流推定部(22)による推定結果に応じて、車載用情報機器(300)における電源回路(16)をオフ状態に設定する制御を実行する電源制御部(25)と、を備える。
