Abstract

The invention provides a vehicle lighting control system which can improve visual identifiability of in-vehicle and out-vehicle at dim dusk. The vehicle lighting control system for controlling headlights of a vehicle and a display device comprises an illuminance detector for detecting an illuminance outside of the vehicle, and a lighting controller for controlling luminances of the headlights and the display device based on the detected illuminance. The lighting controller includes a headlight controlling module for turning the headlights off when the illuminance is above a first threshold, and turning the headlights on when the illuminance is the first threshold or below, and a display device controlling module for controlling the luminance of the display device to a first set value when the illuminance is above a second threshold, and controlling the luminance of the display device to a second set value when the illuminance is the second threshold or below, the second threshold being lower than the first threshold, the second set value being lower than the first set value.

Description

technical field [0001] The present invention relates to a lighting control device for a vehicle, in particular to a lighting control device for controlling the lighting of a display device mounted on a vehicle, such as a display of a navigation system. Background technique [0002] In the past, in order to prevent the driver from being dazzled by the display device such as the display of the navigation device installed on the instrument panel (instrument panel) in the car at night, the vehicle's headlight (headlight) or small light (small light) ) etc. to lower the screen brightness of the display device in conjunction with the lighting of the vehicle lights. [0003] In addition, Patent Document 1 describes that in order to prevent unintended headlight extinguishing, interior lamps such as a meter panel are turned off in conjunction with automatic lighting of the headlights.
