Abstract

A system adapted to provide a warning to a motorist that a nearby vehicle has been in an accident. Embodiments include a crash detector operable to detect a crash of a vehicle, a transmitter to transmit a warning signal (typically, radio frequency) from the crashed vehicle, a receiver to receive a transmitted crash warning signal, and a display to warn the operator of an approaching vehicle of the crash. Some embodiments incorporate feedback from a vehicle'"'"'s air-bag deployment circuitry to provide a trigger effective to broadcast the crash warning signal. Desirably, the operator of an approaching vehicle is provided with at least one, if not both, of a visual and an audible warning signal. Certain embodiments provide such audible and/or visual warning to approaching vehicles via the transmitted warning signal and a display and/or speaker carried in the approaching vehicle. Sometimes, audible and visual warnings may be transmitted directly from the crashed vehicle.

Claims

1. A system comprising:

a first accident detector structured to be carried on board a first motor vehicle and adapted to detect an accident involving the first motor vehicle and to consequently cause a first output;

a first transmitter in communication with the first accident detector and operable to broadcast a first remote warning signal subsequent to receiving the first output;

a first receiver structured to be carried on board the first motor vehicle and operable to receive a second remote warning signal that is transmitted by a different system; and

a first local warning device in communication with the first receiver and effective to communicate a warning, corresponding to the second remote warning signal, to an occupant disposed within the first motor vehicle.

2. The system of claim 1, further comprising:

a second accident detector structured to be carried on board a second motor vehicle and adapted to detect an accident involving the second motor vehicle and to consequently cause a second output;

a second transmitter in communication with the second accident detector and operable to broadcast the second remote warning signal subsequent to receiving the second output;

a second receiver structured to be carried on board the second motor vehicle and operable to receive the first remote warning signal; and

a second local warning device in communication with the second receiver and effective to communicate a warning, corresponding to the first remote warning signal, to an occupant disposed inside the second motor vehicle.

3. The system of claim 1, wherein:

the first accident detector is disposed in-circuit to receive an input from a component of air-bag deployment circuitry of the first motor vehicle.

4. The system of claim 1, further comprising:

a warning light structured to be carried on board the first motor vehicle and adapted to broadcast a warning light output, which is configured to be visible to an occupant of an approaching vehicle, responsive to an output of the first accident detector.

5. The system of claim 4, wherein the warning light is adapted to be carried on top of a roof of the first motor vehicle.

6. The system of claim 4, wherein the warning light comprises an element selected from the group consisting of a brake light, a turn signal, and a headlight of the first motor vehicle.

7. The system of claim 1, further comprising:

an alarm structured to be carried on board the first motor vehicle and adapted to broadcast an audible warning, for perception of the audible warning by an occupant of an approaching motor vehicle, responsive to an output of the first accident detector.

8. The system of claim 7, further comprising:

a warning light structured to be carried on board the first motor vehicle and adapted to broadcast a visible warning light output, for perception of the warning light output by an occupant of an approaching motor vehicle, responsive to an output of the first accident detector.

9. The system of claim 1, wherein the first local warning device comprises a screen on which a printed message may be displayed for observation by an operator of the first motor vehicle.

10. 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 the second signal.

11. The system of claim 10, 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 the second signal;

a plurality of audible noises are individually assigned to each one of the states of intensity; and

a speaker associated with the system is configured to broadcast one noise, selected from the noises and corresponding to the currently determined state, for audible perception of the one noise by an occupant of the first vehicle.

12. The system of claim 11, wherein the first display device further comprises a screen on which a printed message may be displayed, for observation by a driver of the first motor vehicle, responsive to the second signal.

13. The system of claim 12, wherein the message is selected from a plurality of pre-programmed messages based upon a characteristic of the second signal.

14. The system of claim 1, further comprising:

an over-ride control operable to stop broadcast of a signal from the system.

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

16. The system of claim 1, wherein a transmission range for the first transmitted signal is adjustable based upon conditions disposed in the location of a crash.

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

18. A crash warning system comprising:

a crash detector operable to generate an input signal resulting from a crash involving a motor vehicle in which the crash detector is carried, the crash detector comprising a component of an air-bag deployment control assembly of the motor vehicle that is effective to cause the input signal responsive to air-bag deployment caused by the crash;

a transmitter in communication with the crash detector and operable to broadcast a first remote warning signal subsequent to receiving the input signal;

a receiver structured to receive a second remote warning signal from a different crash warning system; and

a display device in communication with the receiver and effective to communicate a local warning, corresponding to the second remote warning signal, to an occupant of the motor vehicle.

19. The crash warning system of claim 18, further comprising:

an alarm adapted to broadcast an audible warning, for perception of the audible warning by an occupant of an approaching motor vehicle, responsive to the input signal; and

a warning light adapted to broadcast a visible warning light output, for perception of the warning light output by an occupant of an approaching motor vehicle, responsive to the input signal.

20. The crash warning system of claim 19, wherein:

the display device is structured to visually convey an estimate of the distance to a broadcast location of the second remote warning signal;

a plurality of audible noises are individually assigned to a corresponding plurality of discrete distance estimates; and

a speaker is operably associated with the crash warning system to broadcast the noise corresponding to the currently displayed distance.
