Abstract

A method is disclosed for detecting potential accident situations with a vehicle driven by a driver. In an embodiment, the method includes collecting behaviour data of the vehicle by sensors located in the vehicle; obtaining a position of the vehicle; transmitting the behaviour data and the position of the vehicle to a control centre; selecting at least one traffic monitoring camera based on the position of the vehicle; acquiring images by the traffic monitoring camera, the images including the vehicle; transmitting the images to the control centre; analysing the behaviour data for detecting a driver'"'"'s abnormal condition; analysing the images for detecting an abnormal condition of the vehicle; and if the two analyses detect an abnormal condition, registering the vehicle in a probable accident list.

Claims

1. A method for detecting potential accident situations with a vehicle driven by a driver, said method comprising:

collecting behaviour data of the vehicle by sensors located in the vehicle,

obtaining a position of the vehicle,

transmitting the behaviour data and the position of the vehicle to a control centre,

selecting at least one traffic monitoring camera based on the position of the vehicle,

acquiring images by said traffic monitoring camera, the images including the vehicle,

transmitting the images to the control centre,

analysing the behaviour data for detecting a driver'"'"'s abnormal condition,

analysing the images for detecting an abnormal condition of the vehicle, and

if the two analyses detect an abnormal condition, registering said vehicle in a probable accident list.

2. The method of claim 1, wherein the driver has a portable device figured to communicate with the control centre, said method further comprising

transmitting, from the control centre, a warning message to said portable device if the driver is registered in the probable accident list.

3. The method of claim 2, wherein the portable device is integrated in said vehicle.

4. The method of claim 2, wherein the portable device includes a geolocation module, configured to determine a current position and it is independent of the vehicle, and wherein the warning message includes the position of the vehicle, the portable device being selected by a comparison between the position of the vehicle and the current position.

5. The method of claim 1, wherein at least one third party has a third party portable device comprising a geolocation module, configured to determine a third party position, said method further comprising:

receiving a warning message containing the position of the vehicle, and

comparing the position of the vehicle with the third party position and if the positions are close to each other, sending an audio and/or visual signal to the third party portable device.

6. The method of claim 1, wherein the detection of a driver'"'"'s abnormal condition is determined by the comparison with reference behaviour data of the vehicle established during a phase of initialization.

7. The method of claim 1, wherein the detection of an abnormal condition of the vehicle includes at least:

extracting, from a database, road requirements near the position of the vehicle, the abnormal condition of the vehicle being detected if the position of the vehicle does not meet the road requirements.

8. The method of claim 7, wherein a road requirement is the maximum speed at the position of the vehicle, said method including:

transmitting a current speed of the vehicle with the driver'"'"'s behaviour data, and

comparing the current speed with the maximum speed, an abnormal condition being established if the current speed is higher than the maximum speed.

9. A system for detecting a potential accident situation of a vehicle driven by a driver, the system comprising:

traffic monitoring cameras,

means for communication with at least one vehicle for receiving behaviour data of the vehicle captured by sensors,

means for receiving a position of said vehicle, and

a control centre, the control centre including

means for selecting at least one monitoring camera based on the position of the vehicle and acquiring images of said camera for monitoring the traffic, the images including the vehicle,

means for analysing the behaviour data to detect a driver'"'"'s abnormal condition, and for analysing the images to detect an abnormal condition of the vehicle, and

means for registering, if the two analyses detect an abnormal condition, said vehicle in a probable accident list.

10. The system of claim 9, wherein the control centre further includes

means for communication with a portable device of said driver, and

means for transmitting a warning message to said portable device if the vehicle is registered in the probable accident list.

11. The system of claim 9, wherein the control centre further includes

means for receiving a position of a third party portable device, and

means for comparing this position with the position of said vehicle and for transmitting a warning message to said third party device if the positions are close to each other.

12. The system of claims 9, further comprising:

means for detecting an abnormal condition of the vehicle by the extraction, from a database, of road requirements near the position of the vehicle, the abnormal condition of the vehicle is detected if the position of the vehicle does not meet the road requirements.

13. The system of claim 9, further comprising:

means for transmitting a warning message to an emergency service.
