Sensors and sound modules that are equipped on vehicle seats or rear mirrors collect diverse information on a driver’s body condition (temperature, breathing rate, amount of carbon dioxide while breathing, tone of voice, used words, facial expression, etc.). Based on such information, the Discomfort Index is calculated. The AC controller uses this index to control the temperature of wind, direction, air volume, and wind speed.
