Abstract

There are provided a black box for a vehicle automatically transmitting an emergency rescue signal at the time of the occurrence of a traffic accident and allowing only authorized persons to access video data at the time of the occurrence of the traffic accident, and an access authorization method thereof. The black box includes: a sensor sensing vehicle impact; a controller performing a control to store video that is being recorded, transmit a rescue signal, permit authorized access to stored video data, when the amount of vehicle impact sensed by the sensor is equal to or greater than a preset reference value; a storing unit storing the recorded video according to the control of the controller; a communicating unit transmitting the rescue signal to a preset object according to the control of the controller; and an authorizing unit authorizing access to the stored video data from the outside.

Claims

1. A black box for a vehicle, the black box comprising:

a sensor sensing vehicle impact;

a controller performing a control to store video that is being recorded, transmit a rescue signal, permit authorized access to stored video data, when the amount of vehicle impact sensed by the sensor is equal to or greater than a preset reference value;

a storing unit storing the recorded video according to the control of the controller;

a communicating unit transmitting the rescue signal to a preset object according to the control of the controller; and

an authorizing unit authorizing access to the stored video data from the outside.

2. The black box of claim 1, wherein the controller performs a control to store video recorded from a first preset time prior to sensing the vehicle impact to a second preset time after sensing the vehicle impact.

3. The black box of claim 1, wherein the controller includes:

a sensor controller receiving the amount of vehicle impact sensed by the sensor and controlling an operation of the sensor;

a camera controller receiving the sensed amount of vehicle impact from the sensor controller and controlling an operation of a camera recording video;

a communication controller controlling communication with the preset object according to the sensed amount of vehicle impact from the sensor controller; and

an authorization controller encrypting the video data stored in the storing unit and permitting access to the encrypted video data when the access is authorized by the authorizing unit.

4. The black box of claim 3, wherein the authorizing unit includes:

a near field communication unit receiving a video data access signal from a user within a preset near field communication range; and

a code confirming unit confirming whether the video data access signal transmitted through the near field communication unit includes a preset authorization key.

5. The black box of claim 4, wherein the near field communication unit communicates in a non-contact near field communication scheme.

6. The black box of claim 5, wherein the near field communication unit communicates in a non-contact near field communication scheme using a frequency of 13.56 Hz or a radio frequency identification (RFID) scheme using a frequency of 900 MHz.

7. An access authorization method of a black box for a vehicle, the access authorization method comprising:

sensing an amount of vehicle impact;

storing video that is being recorded and transmitting a rescue signal to a preset object when the sensed amount of vehicle impact is equal to or greater than a preset reference value; and

confirming whether access to stored video data is an authorized access.

8. The access authorization method of claim 7, wherein the storing of the video that is being recorded includes storing video recorded from a first preset time prior to sensing the vehicle impact to a second preset time after sensing the vehicle impact.

9. The access authorization method of claim 7, wherein the confirming of the authorized access includes encrypting the stored video data and permitting access to the encrypted video data when the access is authorized.

10. The access authorization method of claim 9, wherein the confirming of the authorized access includes receiving a video data access signal from a user within a preset near field communication range, and confirming whether the video data access signal includes a preset authorization key.

11. The access authorization method of claim 10, wherein the confirming of the authorized access includes communicating in a non-contact near field communication scheme.

12. The access authorization method of claim 11, wherein the confirming of the authorized access includes communicating in a non-contact near field communication scheme using a frequency of 13.56 Hz or a radio frequency identification (RFID) scheme using a frequency of 900 MHz.
