PROBLEM TO BE SOLVED: To improve visibility of inside and outside of a vehicle during twilight when outside of a vehicle is dim.SOLUTION: A vehicular illumination control device (10) for performing control of a head light (11) of a vehicle (1) and a display device (12) for displaying vehicle information on inside of the vehicle, comprises: an illuminance sensor (21) for detecting illuminance of outside of the vehicle; and an ECU (100) for controlling the head light (11) and the display device (12) based on the illuminance of outside of the vehicle detected by the illuminance sensor (21). The ECU (100) comprises: a head light control part for putting off the head light (11) when the illuminance of outside of the vehicle is higher than a first threshold, and putting on the head light (11) when the illuminance of outside of the vehicle is equal to or less than the first threshold; and a display device control part for setting a brightness of the display device (12) to a first set value when the illuminance of outside of the vehicle is higher than a second threshold which is set to become lower than the first threshold, and reducing the brightness of the display device (12) to a second set value which is lower than the first set value when the illuminance of outside of the vehicle is equal to or less than the second threshold.SELECTED DRAWING: Figure 5
【課題】車外が薄暗くなる薄暮時等の車内及び車外の視認性を向上させる。【解決手段】車両(1)のヘッドライト(11)と車内に車両情報を表示する表示装置(12)の制御を行うための車両用照明制御装置(10)であって、車外の照度を検出する照度センサ(21)と、照度センサ(21)によって検出された車外の照度に基づいて、ヘッドライト(11)と表示装置(12)を制御するECU(100)と、を備え、ECU(100)は、車外の照度が第1閾値より高いとき、ヘッドライト(11)を消灯させ、車外の照度が第1閾値以下のとき、ヘッドライト(11)を点灯させるヘッドライト制御部と、車外の照度が第1閾値よりも低く設定された第2閾値より高いとき、表示装置(12)の輝度を第1設定値とし、車外の照度が第2閾値以下のとき、表示装置(12)の輝度を第1設定値よりも低い第2設定値まで低減する表示装置制御部と、を有することを特徴とする。【選択図】図5
