Vehicle collision avoidance system and method
First Claim
1. A system for providing input to a control system of an operating vehicle, said system comprising a forward-facing signal sensor, said forward facing signal sensor operable to detect transmitted data signals reflecting a presence, relative distance and relative location of a first forward obstruction in or near a travel lane in front of said operating vehicle;
- an on-board vehicle status sensor configured to generate a status signal, wherein said status signal comprises a speed of said operating vehicle;
a processor configured to receive data from said forward-facing signal sensor and said status sensor and said processor adapted to process said transmitted data and a status operating information signal to determine a separate distance, a speed, and an acceleration or a deceleration of said forward obstruction with respect to said operating vehicle;
said forward-facing signal sensor further adapted to receive a relay signal from said forward obstruction, said relay signal originating from a source remote from said forward obstruction and relating to a second forward obstruction; and
a rear-signal transmitter, said rear-signal transmitter adapted to transmit information to a following vehicle, said information comprising said status signal and information from said forward-facing signal sensor indicating said presence and relative distance of said first forward obstruction and second forward obstruction; and
a vehicle control signal, wherein said vehicle control signal is generated in response to a collision avoidance algorithm run by said processor that uses data from a forward-facing signal detector, said status operating information and said relay signal in an event that said algorithm determines that a collision is imminent.

Abstract
A vehicle control system is disclosed that includes a forward-facing signal sensor operable to detect transmitted data signals reflecting a presence, relative distance and relative location of a first forward obstruction in front of a vehicle, an on-board vehicle status sensor configured to generate a status signal reflecting the speed of the vehicle, a processor to receive the transmitted data signals the forward obstruction and (2) the status sensor signals and (3) a relay signal receiver adapted to receive a signal from the forward obstruction and originating from a source remote from the forward obstruction, and a signal transmitter adapted to transmit information to a following vehicle, wherein the information includes the status signal and information from said forward facing signal sensor and the relay signal and the processor creates a vehicle control signal in response to a collision avoidance algorithm run by the processor that uses data from said forward facing signal detectors, the status signal and the relay signal in the event that said algorithm determines that a collision is imminent.
