Abstract

A system adapted to provide a warning to a vehicle operator of nearby hazards, e.g., that a nearby vehicle has been in a collision or is otherwise inoperable. Embodiments include a detector operable to detect a hazard, a transmitter to transmit a warning signal, a receiver to receive a transmitted warning signal, and a display to warn the operator of an approaching vehicle of the hazard. Some embodiments incorporate feedback from a vehicle'"'"'s airbag deployment circuitry to provide a trigger effective to broadcast the warning signal. The operator of an approaching vehicle may be provided with a visual and/or an audible warning signal, e.g., via a cellular telephone. Certain embodiments provide such warning to approaching vehicles via the transmitted warning signal and a display and/or speaker carried in the approaching vehicle. Audible and visual warnings may be transmitted directly from the crashed vehicle.

6. The system of claim 4, wherein the warning light comprises a light selected from the group consisting of a brake light, a turn signal light, a taillight, a running light, a fog light, and a headlight.

7. The system of claim 1, further comprising:

an alarm structured to be carried onboard the first vehicle and adapted to broadcast an audible warning responsive to the first output or the second output.

8. The system of claim 1, wherein the first local warning device comprises a screen configured to display a printed message.

9. The system of claim 1, wherein the first local warning device is structured to visually convey the instantaneous intensity, selected from a range of intensity, of an attribute associated with at least one of the first remote warning signal and the external remote warning signal.

10. The system of claim 9, wherein:

the first local warning device is structured to determine and visually convey an approximate current state of intensity, selected from a plurality of different states of intensity, of an attribute associated with at least one of the first remote warning and the external remote warning signal;

each of a plurality of sounds is individually assigned to one of the states of intensity; and

a speaker associated with the system is configured to broadcast at least one sound of the plurality and corresponding to the currently determined state.

11. The system of claim 10, wherein the first local warning device further comprises a screen configured to display a printed message responsive to at least one of the first remote warning signal and the external remote warning signal.

12. The system of claim 11, wherein the message is selected from a group of pre-programmed messages based upon a characteristic of at least one of the first remote warning signal and the external remote warning signal.

13. The system of claim 1, further comprising an override control operable to terminate broadcast of the first remote warning signal.

14. The system of claim 13, wherein the override control is structured to be operable only after a pre-programmed period of time has elapsed subsequent to first broadcast of the first remote warning signal.

15. The system of claim 1, wherein a transmission range of the first remote warning signal is adjustable.

16. The system of claim 1, wherein the first transmitter is disposed in-circuit operably to rebroadcast the external remote warning signal.

17. The system of claim 1, wherein:
