Accident information management appratus, vehicle including the same, and accident information management method
An accident information management apparatus for acquiring accident associated information such as images stored in a black box (i.e., black box images) from a peripheral vehicle through direct communication between vehicles when an accident such as a traffic accident occurs, a vehicle including the accident information management apparatus, and a method for managing accident information are disclosed. The vehicle includes an antenna array having a plurality of antenna elements configured to transmit and receive a signal; and a beamformer configured to adjust a phase of the signal transmitted from the antenna elements so as to form a beam pattern focused in a specific direction; and a controller configured to focus the beam pattern onto a peripheral vehicle so as to control a communication unit to transmit a request signal of accident associated information. The antenna array and the beamformer are contained in the communication unit.

a controller configured to control the communication unit to request at least one of accident associated information and vehicle state information from the first peripheral vehicle, and to select a witness vehicle on the basis of any one of the accident associated information and the vehicle state information received from the first peripheral vehicle,
wherein the controller analyzes at least one of the accident associated information and the vehicle state information received from the first peripheral vehicle, and selects a second peripheral vehicle, having captured an event generated in the vehicle during a predetermined time before or after an accident occurrence time, as the witness vehicle,
wherein the accident associated information received from the first peripheral vehicle includes an accident associated image captured by the first peripheral vehicle and includes at least one of a position of an image sensor mounted to the first peripheral vehicle and a position of the first peripheral vehicle shown in the captured image and an attitude of the first peripheral vehicle shown in the captured image, and
wherein the vehicle state information received from the first peripheral vehicle includes at least one of a speed, the position, and the attitude of the first peripheral vehicle and the second peripheral vehicle located in the vicinity of the first peripheral vehicle.
2. The vehicle according to claim 1 , wherein the controller controls the communication unit to request at least one of the accident associated information and the vehicle state information from all the first peripheral vehicles located in a predetermined radius of the vehicle.
3. The vehicle according to claim 1 , wherein the controller controls the communication unit to request the accident associated information from the witness vehicle.
4. The vehicle according to claim 3 , wherein the communication unit requests the accident associated information from the witness vehicle according to a multi-hop communication scheme in which the first peripheral vehicle is used as an intermediate node.
5. The vehicle according to claim 3 , wherein the communication unit receives the accident associated information from the witness vehicle according to a multi-hop communication scheme in which the first peripheral vehicle is used as an intermediate node.
6. The vehicle according to claim 5 , wherein:
the witness vehicle is a first witness vehicle; and
the controller selects a second witness vehicle on the basis of the accident associated information received from the first witness vehicle.
7. The vehicle according to claim 6 , wherein the communication unit requests the accident associated information from the second witness vehicle and receives the accident associated information from the second witness vehicle, according to the multi-hop communication scheme in which the first peripheral vehicle is used as a first intermediate node and the first witness vehicle is used as a second intermediate node.
8. The vehicle according to claim 1 , wherein the controller controls the communication unit to request the accident associated information from the first peripheral vehicle either at an accident prediction time or at the accident occurrence time.
9. The vehicle according to claim 1 , wherein the controller controls the communication unit to upload the accident associated information received from the first peripheral vehicle, and the witness vehicle, accident associated information and accident occurrence information obtained from the vehicle to a server configured to analyze the accident associated information.
10. An accident information management method for collecting accident associated information from a first peripheral vehicle, the method comprising:
communicating with the first peripheral vehicle through D2D (Device to Device) communication;
requesting at least one of accident associated information and vehicle state information from the first peripheral vehicle; and
selecting a witness vehicle on the basis of any one of the accident associated information and the vehicle state information received from the first peripheral vehicle,
wherein the selecting the witness vehicle includes:
analyzing at least one of the accident associated information and the vehicle state information received from the first peripheral vehicle; and
selecting a second peripheral vehicle, having captured an event generated in the vehicle during a predetermined time before or after an accident occurrence time, as the witness vehicle,
wherein the accident associated information received from the first peripheral vehicle includes an accident associated image captured by the first peripheral vehicle and includes at least one of a position of an image sensor mounted to the first peripheral vehicle and a position of the first peripheral vehicle shown in the captured image and an attitude of the first peripheral vehicle shown in the captured image, and
wherein the vehicle state information received from the first peripheral vehicle includes at least one of a speed, the position, and the attitude of the first peripheral vehicle and the second peripheral vehicle located in the vicinity of the first peripheral vehicle.
11. The accident information management method according to claim 10 , wherein the requesting at least one of accident associated information and vehicle state information from the first peripheral vehicle includes:
requesting at least one of the accident associated information and the vehicle state information from all the peripheral vehicles located in a predetermined radius.
12. The accident information management method according to claim 10 , further comprising:
requesting the accident associated information from the witness vehicle.
13. The accident information management method according to claim 10 , wherein the requesting the accident associated information from the new witness vehicle includes:
requesting the accident associated information from the witness vehicle according to a multi-hop communication scheme in which the first peripheral vehicle is used as an intermediate node.
14. The accident information management method according to claim 13 , further comprising:
receiving the accident associated information from the witness vehicle according to the multi-hop communication scheme in which the first peripheral vehicle is used as an intermediate node.
15. The accident information management method according to claim 14 , wherein the witness vehicle is a first witness vehicle, and further comprising:
selecting a second witness vehicle on the basis of the accident associated information received from the first witness vehicle.
16. The accident information management method according to claim 15 , further comprising:
requesting the accident associated information from the second witness vehicle, and receiving the accident associated information from the second witness vehicle, according to a multi-hop communication scheme in which the first peripheral vehicle is used as an intermediate node and the first witness vehicle is used as a second intermediate node.
17. The accident information management method according to claim 10 , further comprising:
uploading the accident associated information received from the first peripheral vehicle, and the witness vehicle, accident associated information and accident occurrence information obtained from the vehicle to a server configured to analyze the accident associated information.
