Abstract

The present invention is directed to a system and method for providing vehicles with information about an event occurred on a road, capable of effectively providing information about an accident on a road to vehicles driving toward the region where the accident has occurred, even during hours or in regions in which vehicle traffic is low.

Claims

1. A method of providing vehicles with information about an event occurred on a road, comprising:

at a first vehicle running in a first direction on the road, detecting a traffic-interfering event; and

at the first vehicle, broadcasting event information including the location at which the event has occurred, or the heading direction of the first vehicle,

wherein the broadcasted event information is received by a second vehicle running in a second direction that is a different direction from the first direction on the road, and broadcasted by the second vehicle.

2. The method of claim 1, wherein the different direction is a reverse direction of the first direction.

3. A method of providing vehicles with information about an event occurred on a road, comprising:

at a second vehicle running in a second direction on the road, receiving event information including the location at which a traffic-interfering event has occurred, or the heading direction of a first vehicle, from the first vehicle running in a first direction that is a different direction from the second direction on the road; and

at the second vehicle, broadcasting the received event information during a predetermined time period or during a time period for which the second vehicle runs a predetermined distance.

4. The method of claim 3, wherein the broadcasted event information is received by a third vehicle running in the first direction, and provided as a warning to a driver of the third vehicle.

5. The method of claim 3, wherein the event information further includes the time at which the event occurred, or the kind of event.

6. The method of claim 3, wherein the second vehicle provides no warning to the driver of the second vehicle.

7. The method of claim 3, further comprising, at the second vehicle, stopping broadcasting the received event information according to predetermined criteria.

8. The method of claim 7, where the predetermined criteria is the time at which an event has occurred, the time at which the first vehicle has broadcasted the event information, or whether or not a predetermined time period has elapsed from the time at which the second vehicle has received the event information.

9. The method of claim 7, wherein the predetermined criteria is the location at which an event has occurred, the location at which the first vehicle has broadcasted the event information, or whether or not the second vehicle has passed a predetermined distance from the location at which the second vehicle has received the event information.

10. The method of claim 4, wherein the received event information by a third vehicle is broadcasted at the third vehicle during a predetermined time period or during a time period.

11. A method of providing vehicles with information about an event occurred on a road, comprising:

at a plurality of relays arranged along the road, receiving event information including the location at which a traffic-interfering event has occurred, or the heading direction of a first vehicle from the first vehicle running in a first direction on the road; and

at the plurality of relays, broadcasting the received event information,

wherein the broadcasted event information is received by a second vehicle running in a second direction that is a different direction from the first direction on the road along which the plurality of relays are arranged, and the event information is broadcasted during a predetermined time period or during a time period for which the second vehicle runs a predetermined distance.

12. The method of claim 11, wherein the broadcasted event information at the relay or the second vehicle is received by a third vehicle running in the first direction, and provided as a warning to the driver of the third vehicle.

13. The method of claim 11, wherein the received event information by a second vehicle is not provided as a warning to the driver of the second vehicle.

15. The system of claim 13, further comprising an output unit configured to provide a driver with a warning according to the occurrence of a traffic-interfering event, based on the first event information or the second event information,

wherein if the first event information is created, the controller controls the output unit to provide a warning according to the first event information to the driver of the vehicle, and

if the second event information is received, the controller determines whether or not the information about the heading direction of the other vehicle included in the second event information is identical to the heading direction of the vehicle, controls the communication unit to broadcast the second event information during the predetermined time period or during the time period for which the vehicle runs the predetermined distance if the heading direction information included in the second event information is not identical to the heading direction of the vehicle, and controls the output unit to provide the driver of the vehicle with the warning according to the second event information if the information about the heading direction of the other vehicle included in the second event information is identical to the heading direction of the vehicle.

16. The system of claim 15, wherein the output unit provides information about the location of the vehicle and the heading direction of the vehicle for a driver, together with the information about the location of the other vehicle included in the second event information.

17. The system of claim 15, wherein the output unit comprises a speaker or a display.

14. A system of providing a vehicle with information about an event occurred on a road, comprising:

a first detector configured to detect a traffic-interfering event occurred on a road;

a second detector configured to detect the location of the vehicle or the heading direction of the vehicle;

a controller configured to create, if the traffic-interfering event is detected by the first detector, first event information about the vehicle based on the results of detections by the first detector and the second detector; and

a communication unit configured to broadcast the first event information, or to broadcast or receive second event information including a traffic-interfering event detected by another vehicle and the location or heading direction of the other vehicle,

wherein if the first event information is created, the controller controls the communication unit to broadcast the first event information, and if the second event information is received through the communication unit, the controller controls the communication unit to broadcast the second event information during a predetermined time period or during a time period for which the vehicle runs a predetermined distance.

18. The system of claim 14, wherein the first detector comprises at least one detector selected from among a sudden turn detector, a sudden stop detector, a sudden lane change detector, a slide detector, a rollover detector, a collision detector, an airbag inflation detector, and a Klaxon detector.
