Abstract

A system for alerting drivers to the presence of oncoming emergency vehicles. According to an embodiment, the system includes: a first transceiver located in an emergency vehicle for transmitting GPS coordinates of the emergency vehicle, and second transceiver located in an automobile. The second transceiver is receives the transmitted information and determines a proximity of the emergency vehicle relative to the automobile. If the emergency vehicle is within a predetermined proximity of the automobile, the second transceiver causes selective attenuation of audio and video signals currently being output in order to raise driver awareness to audio/video alerts generated by the emergency vehicle.

Claims

1. A method comprising:

transmitting, from an emergency vehicle, information corresponding, at least in part, to GPS coordinates of the emergency vehicle;

receiving the transmitted information at an automobile;

determining a proximity of the emergency vehicle relative to the automobile based, at least in part, on the received information;

outputting an interrupt signal to an infotainment system in the automobile, if the emergency vehicle is within a predetermined proximity thereof;

selectively attenuating audio and video signals currently being output by the infotainment system in response to the interrupt signal, thereby raising driver awareness to audio/video alerts generated by the emergency vehicle;

activating a navigation system within the automobile; and

displaying a visual representation of the emergency vehicle on a map of the navigation system by tracing a traveled path and tracing at least one projected trajectory of the emergency vehicle on the map.

2. The method of claim 1, further comprising outputting at least one audio message inside the automobile to indicate at least one of a distance to the emergency vehicle and a travel direction of the emergency vehicle.

5. The method of claim 1, wherein the transmitting comprises:

transmitting, from at least one emergency vehicle to a satellite, information corresponding, at least in part, to GPS coordinates of the at least one emergency vehicle; and

broadcasting, from the satellite to one or more automobiles, the GPS coordinates of the at least one emergency vehicle.

6. The method of claim 1, wherein the transmitting comprises:

transmitting, from at least one emergency vehicle to at least one of a mobile network or a base station of a satellite communication system, information corresponding, at least in part, to GPS coordinates of the at least one emergency vehicle; and

broadcasting, from the mobile network and/or the base station to one or more automobiles, the GPS coordinates of the at least one emergency vehicle.

7. The method of claim 1, wherein the emergency vehicle transmits the information over an open FM radio band, and further comprising tuning the infotainment system to the open FM radio band in response to the interrupt signal.

8. The method of claim 1, wherein the predetermined proximity is automatically set based, at least in part, on a speed and/or heading of the automobile.

9. The method of claim 1, further comprising manually setting the predetermined proximity.

21. The method of claim 1, wherein displaying a visual representation further comprises:

displaying potential points of collision on the map; and

continuously updating the potential points of collision in real time.

22. The method of claim 1, further comprising eliminating one or more of the projected trajectories of the emergency vehicle, based on the instantaneous position of the emergency vehicle.

24. The method of claim 1, wherein the second transceiver is further configured to eliminate one or more of the projected trajectories of the emergency vehicle, based on the instantaneous position of the emergency vehicle.

11. A system comprising:

a first transceiver located in an emergency vehicle for transmitting information corresponding, at least in part, to GPS coordinates of the emergency vehicle; and

a second transceiver located in an automobile and configured to;

receive the transmitted information,

determine a proximity of the emergency vehicle relative to the automobile based, at least in part, on the received information,

output an interrupt signal, if the emergency vehicle is within a predetermined proximity thereof,

cause an infotainment system to selectively attenuate audio and video signals currently being output in response to the interrupt signal, thereby raising driver awareness to audio/video alerts generated by the emergency vehicle,

activate a navigation system within the automobile, and

cause the navigation system to display a visual representation of the emergency vehicle on a map thereof by tracing a traveled path and tracing at least one projected trajectory of the emergency vehicle on the map.

12. The system of claim 11, wherein the second transceiver is further configured to cause the infotainment system to output an audio message inside the automobile to indicate at least one of a distance to the emergency vehicle and a travel direction of the emergency vehicle.

15. The system of claim 11, further comprising:

a satellite,

wherein, the first transceiver is configured to transmit the information to the satellite, and

wherein the satellite is configured to broadcast the GPS coordinates of the emergency vehicle to one or more automobiles.

16. The system of claim 11, wherein:

the first transceiver is configured to transmit the information to at least one of a mobile network or a base station of a satellite communication system; and

the second transceiver is configured to receive the information when it is broadcast by the mobile network and/or the base station.

17. The system of claim 11, wherein:

the first transceiver is configured to transmit the information over an open FM radio band; and

the second transceiver is further configured to cause the infotainment system to tune to the open FM radio band in response to the interrupt signal.

18. The system of claim 11, wherein the second transceiver is further configured to automatically set the predetermined proximity based, at least in part, on a speed and/or heading of the automobile.

19. The system of claim 11, wherein the second transceiver is further configured to receive, as input, a value for the predetermined proximity.

20. The system of claim 11, further comprising a middleware circuit interfaced to the infotainment system and configured to cause the infotainment system to selectively attenuate audio and video signals currently being output in response to the interrupt signal, thereby raising driver awareness to audio/video alerts generated by the emergency vehicle.

23. The system of claim 11, wherein the second transceiver is further configured to:

display potential points of collision on the map; and

continuously update the potential points of collision in real time.
