Description

1. Area The present invention relates to a lighting control system, a lighting control method and a vehicle, in particular a lighting control system, a lighting control method and a vehicle that use location information corresponding to driving data. Description of the state of the art With the increasing use of light-emitting diodes (LEDs) as light sources in vehicle lights, the number of high-beam and low-beam modules with varying performance characteristics has also increased. In particular, a trend towards the integration of high-beam and low-beam vehicle modules has emerged, attracting considerable attention in the market due to their low cost, compact design, simple construction, and comprehensive functionality. As public interest in road safety increases, a significant number of traffic accidents occur each year due to the improper use of high beams. A vehicle lighting module with an Intelligent Front Lighting System (IFS) can, to a certain extent, resolve the conflict between high and low beams. This means the vehicle lighting module provides excellent visibility for the driver while preventing glare from other drivers. The IFS function incorporates a type of intelligent control that can regulate the illumination area and brightness in real time by independently controlling each LED, effectively preventing glare from other vehicles and pedestrians. In existing vehicles equipped with IFS (Intelligent Front-lighting System), the driver directly sets a speed at which the IFS activates, and the system is automatically activated when the vehicle exceeds this speed. However, this existing method has the disadvantage of controlling the lighting without considering the surroundings of the road. This results in the lights being dimmed on relatively dark roads or brighter in relatively bright areas, impairing the visibility of pedestrians or other drivers. The IFS may activate earlier than the driver intends, potentially leading to numerous malfunctions due to camera detection errors, or it may activate later than desired, causing frustration. It is common for drivers to be unaware of the IFS function, even though the vehicle is equipped with it, and therefore not use it. A procedure is therefore needed to automatically activate the IFS function according to the road environment and the driver's preferences.
