Description

  The present invention relates to a vehicle interior light control device, and more particularly to an apparatus configured to reduce a delay time when an interior light is automatically turned off after opening and closing a door after switching an ignition key from on to off.

  Conventionally, in a vehicle interior light control device, control is performed so that an interior key such as an ignition key illumination lamp or a room lamp in the vehicle interior is turned on and off in conjunction with the opening and closing operation of the vehicle door. The interior light is turned on, and when the door is closed, the interior light is turned off after a predetermined delay time has elapsed (15 seconds) to ensure auxiliary lighting for passengers after getting on and off the vehicle.

  In this way, even when there are no passengers in the vehicle after getting off, the room lights are automatically turned off after a predetermined delay time has elapsed after the door is closed, and the room lights remain on for a long time without passengers in the vehicle after getting off the vehicle. If this is the case, the passenger may mistakenly forget to close or turn off the door, and may cause the passenger to check for unnecessary turning off. Further, there is a problem that the power consumption of the battery increases. Therefore, when there is no passenger in the vehicle after getting off, it is necessary to shorten the delay time when the room light is automatically turned off so as not to perform unnecessary lighting.

For example, in the vehicle room lamp control device disclosed in Patent Document 1, when the door is closed and the door is locked after the door is closed, the room lamp is controlled to be turned off after a predetermined delay time has elapsed. There is disclosed a system in which the room lamp is turned off and the lighting time of the room lamp is shortened when there is no passenger in the vehicle after getting off.
