As shown in the flow chart of Figure 3, by installing the Bluetooth communication module and the mobile phone communication module in the black box of the present invention can check the surrounding state of the vehicle in real time through a portable terminal (mobile phone, PDA, etc.) in the absence of the driver. .

When the driver is absent with the vehicle stopped, the image data photographed by the four-side detection camera 10 is continuously stored in the first memory 32.

In this case, the user can communicate with the Bluetooth communication module 38 or the mobile phone communication module 40 in the black box 100 using the terminal 42.

That is, the user terminal (via a method of inputting a password through the keypad of the terminal 42 that the user carries or setting a transmission cycle reservation time to the Bluetooth communication module 38 or the mobile phone communication module 40). 42) and the communication between the Bluetooth communication module 38 or the mobile phone communication module 40 is enabled.

Subsequently, when the driver input voice is output from the Bluetooth communication module 38 or the mobile phone communication module 40 to the vehicle speaker, the voice is transmitted to a person around the vehicle.

Subsequently, a voice (for example, when the driver asks to pull out the vehicle) when a person near the vehicle responds to the driver through the voice module in the Bluetooth communication module 38 or the voice module in the mobile phone communication module 40. The conversation is made by way of being passed back to the terminal 42.

In this way, it is possible to observe the case of people in the vicinity of the vehicle to obtain the anti-theft effect, it is possible to talk quickly to stop parking.

6 is a flowchart illustrating a state of checking a battery level due to a camera operating regardless of starting on / off, as another example of a vehicle accident management method using a vehicle black box according to the present invention.

As described above, as the image photographing of the cameras installed in the front, rear, and both sides of the vehicle is performed through the battery power regardless of the on / off of the vehicle, it may occur when the remaining amount of the battery falls below the reference value.

Therefore, when the battery remaining amount sensor 24 transmits a signal to which the remaining amount of the battery is detected to be less than the reference value to the microprocessor 30, the microprocessor 30 is the Bluetooth communication module 38 or the mobile phone communication module ( The warning message is transmitted to the driver's terminal 42 through the driver 40, whereby the driver can quickly respond to the charging of the battery.

On the other hand, when the user does not carry the terminal 42 through the mobile phone communication module 40 can open its own website connected to the server of the mobile phone company, it is possible to check the image data and vehicle driving information.

The video and audio data stored in the first memory 32 and the vehicle state information stored in the second memory 34 are transmitted to the user terminal 42 through the Bluetooth communication module 38 or the mobile phone communication module 40. When the vehicle is originally out of the parking position, the vehicle is found to be stolen, and the steering wheel, brake, or accelerator pedal of the vehicle can be wirelessly adjusted to stop the vehicle.

That is, when it is determined that the vehicle is stolen out of the parking lot, the signal is transmitted to the microprocessor 30 through the stable communication network while operating the user terminal 42 wirelessly, and the microprocessor is a handle servomotor connected to the output side. And, the operation signal is sent to the solenoid mounted on the brake and the accelerator pedal, the handle is rotated arbitrarily, or the braking and acceleration proceeds arbitrarily to stop the vehicle.
