APPARATUS AND METHOD OF ALARMING INDOOR VENTILATION OF VEHICLE

摘要

PURPOSE: A method of alarming indoor ventilation of a vehicle is provided to prevent a driver from dozing off behind the wheel by controlling the indoor condition of a vehicle with an automatic temperature control system. CONSTITUTION: A method of alarming indoor ventilation of a vehicle comprises the steps of: deciding if velocity of a vehicle is higher than critical reference after operating an automatic temperature control system; deciding if CO2 density is over the critical reference and it passes certain reference time; operating an alarm system after the reference time and resetting a timer if the indoor state of a vehicle is lower than the critical reference; and operating the automatic temperature control system. Therefore, the method prevents a driver from dozing off behind the wheel by controlling the indoor state of the vehicle with the automatic temperature control system.
