Control system and method for auto-light

A control system for an automatic lighting system in a vehicle, the system comprising:

• a sensor configured to detect an illumination level;
• and
• a controller configured to receive position data, determine whether the vehicle has entered a tunnel based on the position data, receive data related to a reference tunnel illumination level of the particular section in the tunnel, compare a sensed illumination level by the sensor with the reference tunnel illumination level, and change a reference light illumination level for turning on/off lights of the vehicle when the difference between the sensed illumination level and the reference tunnel illumination level is a particular value or more.

A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:

• program instructions that determine whether a vehicle has entered a tunnel based on position data,
• program instructions that compare a sensed illumination level with a reference tunnel illumination level, and change a reference light illumination level for turning on/off lights of the vehicle when the difference between the sensed illumination level and the reference tunnel illumination level is a specific value or more.
