Abstract

A system configured to alert drivers of hazards. The system includes at least one sensor of a subject vehicle that is configured to detect one or more hazards proximate to the subject vehicle. A hazard detection module is configured to identify hazards nearby the subject vehicle based on data collected by the at least one sensor. A warning device of the subject vehicle is configured to alert nearby secondary vehicles that the subject vehicle has identified a hazard.

Claims

1. A system configured to alert drivers of hazards comprising:

at least one sensor of a subject vehicle configured to detect one or more hazards proximate to the subject vehicle;

a hazard detection module configured to identify hazards nearby the subject vehicle based on data collected by the at least one sensor; and

a warning device of the subject vehicle configured to alert nearby secondary vehicles that the subject vehicle has identified a hazard.

2. The system of claim 1, wherein:

the at least one sensor includes at least one of a camera, radar, sonar, lidar, temperature sensor, pressure sensor, wind speed sensor, and audio sensor.

3. The system of claim 1, wherein:

the at least one sensor is configured to detect at least one of the following;

the subject vehicle'"'"'s proximity to the hazard, lane position of the subject vehicle, traffic conditions, road conditions, and weather.

4. The system of claim 1, wherein the at least one sensor includes at least one of a lane departure detection sensor, a proximity sensor, an object detection sensor, and an environmental sensor.

5. The system of claim 1, wherein the at least one sensor is configured to detect at least one of the following:

vehicles, including law enforcement and emergency vehicles;

pedestrians;

animals; and

road conditions.

6. The system of claim 1, wherein the at least one sensor of the subject vehicle is configured to identify a warning generated by a secondary vehicle, the warning including hazard lights, emergency lights, and an audible warning including a siren.

7. The system of claim 1, wherein the hazard detection module is configured to identify one or more of the following hazards:

a secondary vehicle along a roadside;

a disabled vehicle;

an emergency vehicle;

a law enforcement vehicle;

an obstacle;

an animal; and

slippery road conditions.

8. The system of claim 1, wherein the warning device includes at least one of a visual warning and an audible warning.

9. The system of claim 8, wherein the visual warning includes hazard lights.

10. The system of claim 8, wherein the audible warning includes at least one of a semantic alert, a horn, and a speech tacton alert.

11. The system of claim 1, further comprising a receiver for the subject vehicle configured to receive a transmission identifying a hazard;

wherein the transmission identifies at least one of the following;

an accident;

a traffic jam;

dangerous road conditions;

a disabled vehicle;

a road obstruction;

an emergency vehicle;

a law enforcement vehicle; and

a hazard detected by one or more nearby secondary vehicles.

12. The system of claim 1, further comprising a transmitter configured to transmit to secondary vehicles information regarding a hazard identified by the hazard detection module.

13. The system of claim 1, further comprising a notification device configured to notify the driver of the subject vehicle that the warning device has been activated by a controller of the system in response to identification of a hazard by the hazard detection module.

14. A method for alerting drivers of hazards comprising:

detecting a hazard with a hazard detection module of a subject vehicle based on data from at least one sensor of the subject vehicle, the at least one sensor configured to detect one or more hazards proximate to the subject vehicle; and

activating a warning device of the subject vehicle configured to alert nearby secondary vehicles that the subject vehicle has identified a hazard, upon detection of the hazard by the hazard detection module.

15. The method of claim 14, further comprising detecting at least one of the following with the at least one sensor:

the subject vehicle'"'"'s proximity to the hazard;

lane position of the subject vehicle;

traffic conditions; and

environmental conditions including road conditions; and

wherein the at least one sensor includes at least one of a camera, radar, sonar, and lidar.

16. The method of claim 14, further comprising detecting one or more of the following hazards with the hazard detection module:

a secondary vehicle along a roadside;

a disabled vehicle;

an emergency vehicle;

a law enforcement vehicle;

an obstacle;

an animal; and

slippery road conditions.

17. The method of claim 14, wherein activating the warning device includes activating at least one of a visual warning and an audible warning, the visual warning includes hazard lights of the subject vehicle.

18. The method of claim 14, further comprising receiving with a receiver of the subject vehicle a transmission identifying a hazard;

wherein the transmission identifies at least one of the following;

an accident;

a traffic jam;

dangerous road conditions;

a disabled vehicle;

a road obstruction;

an emergency vehicle;

a law enforcement vehicle; and

a hazard detected by one or more nearby secondary vehicles.

19. The method of claim 14, further comprising transmitting from the subject vehicle to secondary vehicles information regarding a hazard identified by the hazard detection module.

20. The method of claim 19, wherein warning devices of the secondary vehicles are activated in response to receipt by the secondary vehicles of the information regarding the hazard identified by the hazard detection module of the subject vehicle.
