Abstract

Disclosed are an apparatus and a method of requesting an emergency call (E-Call) for a vehicle accident, which request an E-Call for a vehicle accident by using driving information obtained during travelling of a vehicle. An apparatus for requesting an E-Call for a vehicle accident according to the present invention includes: a travelling information detecting unit configured to detect travelling information about a vehicle for each predetermined time; a vehicle accident determining unit configured to determine whether an accident occurs in the vehicle based on the travelling information; and an E-Call signal transmitting unit configured to transmit an E-Call signal for the vehicle accident with a current location of the vehicle when it is determined that the accident occurs in the vehicle.

Claims

1. An apparatus for requesting an emergency call (E-Call) for a vehicle accident, comprising:

a travelling information detecting unit configured to detect travelling information about a vehicle for each predetermined time;

a vehicle accident determining unit configured to determine whether an accident occurs in the vehicle based on the travelling information; and

an E-Call signal transmitting unit configured to transmit an E-Call signal for the vehicle accident with a current location of the vehicle when it is determined that the accident occurs in the vehicle.

2. The apparatus of claim 1, wherein the travelling information detecting unit detects information on a gear state of a transmission mounted in the vehicle or a current speed of the vehicle as the travelling information.

3. The apparatus of claim 2, wherein when the information on the gear state represents another mode, except for a parking (P) mode and a neutral (N) mode, the current speed is equal to or smaller than a first reference speed, or the information on the gear state or the current speed is not detected, the vehicle accident determining unit determines that the accident occurs in the vehicle.

4. The apparatus of claim 2, wherein the travelling information detecting unit detects a current time, at which the current speed is detected, together, and

when the current speed is 0, a difference value between a previous speed and the current speed is equal to or greater than a first reference value, and a difference value between a previous time, which is detected together with the previous speed, and the current time is equal to or smaller than a second reference value, the vehicle accident determining unit determines that the accident occurs in the vehicle.

5. The apparatus of claim 2, wherein the vehicle accident determining unit is operated when the information on the gear state represents another mode, except for the P mode and the N mode, and the current speed is equal to or greater than a second reference speed.

6. The apparatus of claim 1, further comprising:

a collision determining unit configured to determine whether the vehicle collides with an object located outside the vehicle,

wherein the vehicle accident determining unit determines whether the accident occurs in the vehicle according to whether the vehicle collides with the object.

7. The apparatus of claim 6, wherein the collision determining unit determines whether the vehicle collides with the object by using at least one of a camera for photographing a front side of the vehicle, a radar for detecting the object at each side of the outside of the vehicle, and an acceleration sensor for measuring an acceleration of the vehicle.

8. The apparatus of claim 7, wherein in the case where the collision determining unit determines whether the vehicle collides with the object by using the camera, when a distance to the object in the image obtained by the camera is equal to or smaller than a first reference distance, an image is not obtained by the camera for a predetermined time, or a detection signal for the camera is not detected, the collision determining unit determines that the vehicle collides with the object,

in the case where the collision determining unit determines whether the vehicle collides with the object by using the radar, when a distance to the object obtained by the radar is equal to or smaller than a second reference distance, or a detection signal for the radar is not detected, the collision determining unit determines that the vehicle collides with the object, and

in the case where the collision determining unit determines whether the vehicle collides with the object by using the acceleration sensor, when an intensity of an impact measured by the acceleration sensor is equal to or greater than a reference intensity, the collision determining unit determines that the vehicle collides with the object.

9. The apparatus of claim 1, further comprising:

a location detecting unit configured to detect a location of the vehicle and measure a time, at which the location is detected; and

a door lock detecting unit configured to detect information on a door lock state of the vehicle,

wherein when a location of the vehicle detected at a previous time is equal to a location of the vehicle detected at a current time, and door lock release information about the vehicle is not detected for a predetermined time between the previous time and the current time, the vehicle accident determining unit determines that the accident occurs in the vehicle.

10. The apparatus of claim 1, wherein the E-Call signal transmitting unit transmits the E-Call signal by using at least one of a first terminal, which is mounted in the vehicle and capable of transceiving data, a second terminal carried by a driver of the vehicle, and a third terminal, which is capable of transceiving data with the first terminal.

11. A method of requesting an emergency call (E-Call) for a vehicle accident, comprising:

detecting travelling information about a vehicle for each predetermined time;

determining whether an accident occurs in the vehicle based on the travelling information; and

transmitting an E-Call signal for the vehicle accident with a current location of the vehicle when it is determined that the accident occurs in the vehicle.

12. The method of claim 11, wherein the detecting of the travelling information includes detecting information on a gear state of a transmission mounted in the vehicle or a current speed of the vehicle as the travelling information.

13. The method of claim 11, further comprising:

determining whether the vehicle collides with an object located outside the vehicle,

wherein the determining whether the accident occurs in the vehicle includes determining whether the accident occurs in the vehicle according to whether the vehicle collides with the object.

14. The method of claim 11, further comprising:

detecting a location of the vehicle and measuring a time, at which the location is detected; and

detecting information on a door lock state of the vehicle,

wherein the determining whether the accident occurs in the vehicle includes determining that the accident occurs in the vehicle when a location of the vehicle detected at a previous time is equal to a location of the vehicle detected at a current time, and door lock release information about the vehicle is not detected at the previous time and the current time.
