Abstract

Systems and methods for transmitting signals concerning the location of an emergency vehicle to other cars traveling in the vicinity of the emergency vehicle alert the other vehicles to the presence of the emergency vehicle. A transmitter unit which is desirably automatically switched on whenever the flashing lights and sirens of the emergency vehicle are activated. transmits a signal preferably only within a limited range adjacent or near the emergency vehicle. The transmitted signal preferably identifies the present location and direction of the emergency vehicle. The location and direction information of the emergency vehicle is preferably provided by GPS data generated by a GPS system associated with the emergency vehicle. Automobiles and other vehicles are outfitted with receivers for receiving the signals transmitted by emergency vehicles as described above. Once a signal is received which indicates that an emergency vehicle is operating nearby, the receiver unit processes the signal and then ultimately triggers an alert to the mechanism that is in the vehicle and may be included within the receiver unit. The alert mechanism may be comprised of a flashing light or an audible tone or a recorded message that plays back a statement that indicates the presence of the emergency vehicle nearby.

Claims

1. A method for alerting vehicles to the presence of an emergency vehicle comprising steps of:

transmitting a signal which indicates the presence of an emergency vehicle to a plurality of vehicles;

receiving the signal in a vehicle traveling near an emergency vehicle; and

generating an alarm signal which indicates the presence of the emergency vehicle.

2. The method of claim 1, wherein the alarm signal is comprised of a flashing light.

3. The method of claim 1, wherein the alarm signal is comprised of a recorded message.

4. The method of claim 1, wherein the alarm signal is comprised of an audible tone.

5. The method of claim 1, wherein the step of receiving the signal is comprised of a step of receiving the signal with a receiver that receives FM radio signals.

6. A method for alerting vehicles to the presence of an emergency vehicle comprising steps of:

transmitting a signal which indicates the location of an emergency vehicle to a plurality of vehicles;

receiving the signal in a vehicle traveling near an emergency vehicle; and

generating an alarm signal which indicates the presence of the emergency vehicle.

7. The method of claim 6, wherein the alarm signal is comprised of a flashing light.

8. The method of claim 6, wherein the alarm signal is comprised of a recorded message.

9. The method of claim 6, wherein the alarm signal is comprised of an audible tone.

10. The method of claim 6, wherein the step of receiving the signal is comprised of a step of receiving the signal with a receiver that receives FM radio signals.

11. The method of claim 6, wherein the location information is comprised of GPS data.

13. The method of claim 12, wherein the alarm signal is comprised of a flashing light.

14. The method of claim 12, wherein the alarm signal is comprised of a recorded message.

15. The method of claim 12, wherein the alarm signal is comprised of an audible tone.

16. The method of claim 12, wherein the step of receiving the signal is comprised of a step of receiving the signal with a receiver that receives FM radio signals.

17. The method of claim 12, wherein the location information is comprised of GPS data.

19. The system of claim 18, wherein the means for generating an alarm signal is comprised of a flashing light.

20. The system of claim 18, wherein the means for generating an alarm signal is comprised of a stored message.

21. The system of claim 18, wherein the means for generating an alarm signal is comprised of an audible tone sound source.

22. The system of claim 18, wherein the means for receiving the signal is comprised of an FM radio receiver.

24. The system of claim 23, wherein the means for generating an alarm signal is comprised of a flashing light.

25. The system of claim 23, wherein the means for generating an alarm signal is comprised of a stored message.

26. The system of claim 23, wherein the means for generating an alarm signal is comprised of an audible tone.

27. The system of claim 23, wherein the means for receiving the signal is comprised of an FM radio receiver.

28. The system of claim 23, wherein the location information is comprised of GPS data.

30. The system of claim 29, wherein the means for generating an alarm signal is comprised of a flashing light.

31. The system of claim 29, wherein the means for generating an alarm signal is comprised of a stored message.

32. The system of claim 29, wherein the means for generating an alarm signal is comprised of an audible tone sound source.

33. The system of claim 29, wherein the means for receiving the signal is comprised of an FM radio receiver.

34. The system of claim 29, wherein the location information is comprised of GPS data.

12. A method for alerting vehicles to the presence of an emergency vehicle comprising steps of:

transmitting a signal which indicates the location and direction of an emergency vehicle to a plurality of vehicles;

receiving the signal in a vehicle traveling near an emergency vehicle; and

generating an alarm signal which indicates the presence of the emergency vehicle.

18. A system for alerting vehicles to the presence of an emergency vehicle comprising:

a means for transmitting a signal which indicates the presence of an emergency vehicle to a plurality of vehicles;

a means for receiving the signal in a vehicle traveling near an emergency vehicle; and

a means for generating an alarm signal which indicates the presence of the emergency vehicle in the vehicle.

23. A system for alerting vehicles to the presence of an emergency vehicle comprising:

a means for transmitting a signal which indicates the location of an emergency vehicle to a plurality of vehicles;

a means for receiving the signal in a vehicle traveling near an emergency vehicle; and

a means for generating an alarm signal which indicates the presence of the emergency vehicle.

29. A system for alerting vehicles to the presence of an emergency vehicle comprising:

a means for transmitting a signal which indicates the location and direction of an emergency vehicle to a plurality of vehicles;

a means for receiving the signal in a vehicle traveling near an emergency vehicle; and

a means for generating an alarm signal which indicates the presence of the emergency vehicle.
