Apparatus and method for controlling an in-vehicle lighting environment

An apparatus for controlling an in-vehicle lighting environment, the apparatus comprising:

• a passenger state determination unit that determines a state of a passenger using a gaze of the passenger photographed by a camera of a vehicle;
• a driving state determination unit that determines a driving state of the vehicle using an acceleration value measured by an acceleration sensor of the vehicle;
• an external environment state determination unit that determines an external environment state of the vehicle using an external illuminance value measured by an external illuminance sensor of the vehicle;
• a lighting environment control unit that controls an illuminance and a color of a first light disposed inside the vehicle based on data determined by at least one determination unit among the passenger state determination unit, the driving state determination unit, and the external environment state determination unit,
• wherein the passenger state determination unit determines that the state of the passenger is a concentration mode when the gaze of the passenger to an inside of the vehicle does not deviate from a predetermined range for a preset period of time or an external gaze mode when the gaze of the passenger to an outside of the vehicle does not deviate from a predetermined range for the preset period of time,
• wherein the driving state determination unit determines that the driving state of the vehicle is a warning mode when a longitudinal acceleration value of the vehicle exceeds a preset value,
• wherein the lighting environment control unit controls the illuminance of the first light to an illuminance set for concentration of the passenger and controls a light shielding apparatus disposed above a window of the vehicle to cover the window of the vehicle when the passenger state determination unit determines that the state of the passenger is in the concentration mode, and
• wherein the lighting environment control unit controls the light shielding apparatus so as not to cover the window of the vehicle when the driving state determination unit determines that the driving state of the vehicle is in the warning mode or when the passenger state determination unit determines that the state of the passenger is in the external gaze mode.
