In the start-off state of the vehicle, the processor 270 may output information on the number of passengers through at least one of the display 251 and the sound output unit 252 (S1235).

After the start-up turn-off, in a state in which all the car doors are closed (S1240), at least one camera 220 photographs an image inside the vehicle, and the processor 270 acquires image data inside the vehicle, and then recognizes a face in the image You can proceed (S1245).

The processor 270 may determine that the power is off when the number of people disembarking and the number of people stored in the memory 240 match. In this case, the processor 270 may perform a malfunction prevention operation (S1251, 1252). The malfunction prevention operation may include an operation of capturing an image through the camera 220 in a predetermined time unit and determining whether there are remaining personnel in the vehicle through face recognition. The malfunction prevention operation may include an operation of capturing an image through the camera 220 and determining whether there are remaining personnel inside the vehicle through face recognition when a cry or snoring noise is detected in the vehicle.

If the number of people disembarking and the number of people boarding stored in the memory 240 do not match, the processor 270 may determine that some people do not get off. In this case, the processor 270 may perform a safety operation (S1150). The safety operation may include transmitting an alarm message and a picture taken by the camera 220 to a preset mobile terminal. The safety operation may include an operation of driving an air conditioner or a heater so that a certain temperature is maintained by checking an internal temperature to prevent choking or verbs. The safety operation may include an operation of connecting to the rescue center after a predetermined time has elapsed and transmitting the photograph and location data captured by the camera 220.

The above-described present invention can be embodied as computer readable codes on a medium on which a program is recorded. The computer-readable medium includes any kind of recording device in which data readable by a computer system is stored. Examples of computer-readable media include a hard disk drive (HDD), solid state disk (SSD), silicon disk drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, and optical data storage device. This includes, and is also implemented in the form of a carrier wave (eg, transmission over the Internet). Also, the computer may include a processor or a control unit. Accordingly, the above detailed description should not be construed as limiting in all respects, but should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
