Abstract

The present disclosure provides an accident alert system for preventing secondary collisions. The system for preventing a secondary accident comprises a terminal configured to have a global positioning system (GPS) navigation capability, monitor and display a driving state and an accident state of a vehicle, transmit information on a driving state and the accident state via a communication network, and display information received on a screen; and a server platform configured to exchange information with the terminal, include an algorithm for determining the occurrence of an accident based on the information on the driving state and the accident state e received from the terminal and traffic information, and inform other terminals of the occurrence of the accident.

Claims

1. A system for preventing a secondary accident, comprising:

a terminal configured to

have a global positioning system (GPS) navigation capability,

monitor and display a driving state and an accident state of a vehicle,

transmit information on the driving state and the accident state via a communication network, and

display information received on a screen; and

a server platform configured to

exchange information with the terminal,

include an algorithm for determining an occurrence of an accident based on the information on the driving state and the accident state received from the terminal, and

inform other terminals of the occurrence of the accident.

2. The system of claim 1, wherein the information on the driving state comprises a speed and a location of the vehicle.

3. The system of claim 2, wherein the information on the driving state further comprises accelerations in three independent directions.

4. The system of claim 3, wherein the terminal is configured to determine whether there is an impact by analyzing the speed and the accelerations and to display the accident state.

5. The system of claim 2, wherein the terminal is configured to display the driving state by determining a stop or drive of the vehicle by analyzing the information on the speed and the location of the vehicle.

6. A method for preventing a secondary accident which follows after a first accident of a vehicle, comprising:

detecting an occurrence of an impact based on acceleration information of the vehicle;

determining whether the vehicle is stopped or not based on a speed of the vehicle if the impact is detected;

identifying an accident if the vehicle is determined to be stopped and checking if the vehicle is stopped for a prescribed duration of time;

determining an occurrence of the accident if it is determined that the vehicle is stopped for the certain duration of time and confirming the occurrence of the accident based on whether trailing vehicles respective to the vehicle present a significant decrease in speed relative to leading vehicles respective to the vehicle; and

notifying the occurrence of the accident to nearby vehicles of the vehicle if the accident is confirmed.

7. The method of claim 6, further comprising:

determining the accident to be cleared if the vehicle moves since the detecting of the impact.

8. The method of claim 6, wherein the occurrence of the impact is detected if an acceleration of the vehicle exceeds an acceleration threshold, and wherein the method includes:

notifying the impact to an accident analysis system and to the nearby vehicles of the vehicle under the impact.

9. The method of claim 6, wherein the determining of whether the vehicle is stopped or not includes:

determining whether the vehicle is in a shadow area out of visibility of a global positioning system (GPS) and determining whether the vehicle is practically stopped even if the speed is not exactly zero by using a location and the acceleration of the vehicle.

10. A system for preventing a secondary accident, comprising:

a terminal configured to

have a global positioning system (GPS) navigation capability,

monitor and display a driving state and an accident state of a vehicle,

transmit information on the driving state and the accident state via a communication network,

display information received on a screen, and

detect an occurrence of an impact; and

a server platform configured to

exchange information with the terminal,

include an algorithm for determining an occurrence of an accident based on the information on the driving state and the accident state received from the terminal, and

inform other terminals of the occurrence of the accident,

wherein the terminal analyzes an acceleration measured by using an accelerometer provided on the vehicle to detect the impact and determine whether the vehicle is in an accident through determining whether the vehicle is stopped based on the driving state at the occurrence of the impact and subsequently and to transmit information on whether the vehicle is in an accident to the server platform.

11. A system for preventing a secondary accident, comprising:

a terminal configured to

have a global positioning system (GPS) navigation capability,

identify information on a driving state, an impact information and a stop information of a vehicle from an acceleration which is received or measured by the terminal,

transmit the information on the driving state, impact information and stop information via a communication network, and

process and display information received on a screen; and

a server platform configured to

exchange information with the terminal,

include an algorithm for determining an occurrence of an accident based on the information on the driving state, impact information and stop information received from the terminal, and

inform other terminals of the occurrence of the accident,

wherein the algorithm is configured to

receive the impact information transmitted from the terminal and deliver a location of the vehicle under the impact to the other terminals, and

confirm the occurrence of the accident based on whether the vehicle under the impact is stopped or not and on speeds of nearby vehicles.
