DIMMING GLASS CONTROL DEVICE AND DIMMING CONTROL SYSTEM

To control a dimming glass as a glass while improving user's convenience regarding vehicle retreat operation.SOLUTION: A dimming glass control device 100 comprises: a voltage application part 110 which changes transmittance depending on existence or absence of AC voltage application to a dimming film of a dimming glass 11 as a rear glass 11a of a vehicle; a situation detection part 120 which detects light-dark situation outside the vehicle, weather conditions, lighting instruction situation for a headlight, operation instruction situation for a rear wiper, and progress of the vehicle; and a control part 130 which causes the voltage application part 110 to reduce transmittance of the dimming film, and prohibits reduction of transmittance when a detection result of the situation detection part 120 indicates a dark state outside the vehicle, a rainy weather state, a lighting-on state of the headlight, an ON state of the rear wiper, and a retreat state of the vehicle.SELECTED DRAWING: Figure 1 【課題】車両の後退操作についてのユーザの利便性を向上させつつリアガラスとしての調光ガラスを制御する。【解決手段】調光ガラス制御装置１００が、車両のリアガラス１１ａとしての調光ガラス１１の調光フィルムに対する交流電圧の印加有無によって透過率を変化させる電圧印加部１１０と、車外の明暗状況、天候状況、ヘッドライトに対する点灯指示状況、リアワイパに対する動作指示状況、及び車両の進行状況、を検知する状況検知部１２０と、電圧印加部１１０に調光フィルムの透過率を低減させるとともに、状況検知部１２０での検知結果が、車外の暗状態、雨天状態、ヘッドライトのライトＯＮ状態、リアワイパのワイパーＯＮ状態、及び車両の後退状態、を示す場合に、透過率の低減を禁止する制御部１３０と、を備えたことを特徴とする。【選択図】図１
