Hazard warning system for vehicles
First Claim
1. A system comprising:
- a first detector structured to be carried onboard a first vehicle and adapted to detect a first hazard and to consequently cause a first output therefrom;
a first transmitter in communication with the first detector and operable to broadcast a first remote warning signal therefrom subsequent to receiving the first output;
a first receiver structured to be carried onboard the first vehicle and operable to receive an external remote warning signal transmitted by another transmitter; and
a first local warning device in operable communication with the first receiver and configured to provide a warning to an occupant of the first vehicle, the warning corresponding to receipt of the external remote warning signal, the first local warning device comprising a display device in communication with the first receiver, wherein;
the display device is structured to visually convey an estimate of the distance to a location of an external hazard associated with the external remote warning signal;
each of a plurality of audible noises is individually assigned to one of a plurality of discrete distance estimates;
a speaker is operably associated with the system to broadcast the noise corresponding to the estimate of the distance; and
an override control operable to terminate broadcast of the first remote warning signal, 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

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.
