Subsequently, the general sensors 10 to 40 detect whether the vehicle is traveling, whether the passenger is present, the room temperature, and the amount of carbon monoxide in the car, respectively (S2).

The driving sensor 10 detects whether the vehicle is in a driving state or a stationary state, and outputs a corresponding detection signal to the main controller 90 (S3). In the main controller 90, the vehicle is in a stopped state. In case of receiving the detection signal output from the human body sensor 20, it is determined whether a person in the vehicle is on board (S4).

When there is a passenger in the stopped state, the main controller 90 receives a signal output from the temperature sensor 30 and compares the indoor temperature with a preset reference temperature in the memory to determine whether the indoor temperature exceeds the reference temperature. (S5, S6).

When the indoor temperature exceeds the reference temperature in the above, the main control unit 90 controls the sunroof driving unit 51 to open the sunroof and ventilate, thereby lowering the room temperature (S7).

Since there is no main control unit 90, the dangerous call unit 70 generates a voice message or a text message to a mobile phone number preset in the memory and transmits it (S10).

When there is a passenger in the stationary state of the vehicle, when the indoor temperature is normal, the main controller 90 receives a signal output from the air pollution sensor 40 and compares the amount of carbon monoxide with a preset reference value in the memory. It is determined whether the reference value is exceeded (S11, S12).

When the amount of carbon monoxide in the vehicle exceeds the reference value, the main control unit 90 controls the sunroof driving unit 51 to open the sunroof and ventilate, thereby lowering the concentration of carbon monoxide in the car (S13).

When the vehicle does not have the sunroof, the fan driving unit 55 is operated to ventilate indoor air with the ventilation fan 56 or the window driving unit 53 is controlled to lower the window 54 to ventilate the indoor air (S14). .

Of course, all of these ventilators can be operated, but at least one of them may be operated, and it is preferable to operate the sunroof 52 first in order to prevent theft.

Subsequently, the main control unit 90 controls the alarm means 60 to output a warning sound into the vehicle to inform the passengers of a choking hazard state (S15), and if the person in the vehicle is a child, the ability to cope with a dangerous situation is not provided. Therefore, the main control unit 90 generates and transmits a voice message or text message to the mobile phone number preset in the memory through the danger call unit (70) (S16).

After operating the asphyxia prevention device as described above, the main control unit 90 continuously detects the signals output from the temperature sensor 30 and the air pollution sensor 40, and, if the room temperature and carbon monoxide falls below the reference value, the main control unit ( 90) stops all emergency operations, and controls to return the ventilation device such as sunroof, window, ventilation fan or air conditioner to the original state (S17, S18).
