1. A hazard warning system comprising:
- hazard detection sensors and a primary transmitter for a primary vehicle that are configured to transmit information regarding a hazard and a path history of the primary vehicle;
a secondary receiver for a secondary vehicle configured to receive the information regarding the hazard detected by the hazard detection sensors and the path history of the primary vehicle;
a secondary vehicle control module configured to notify a driver of the secondary vehicle of the hazard when the secondary vehicle is traveling along a path similar to that of the primary vehicle;
a receiver for the primary vehicle, the receiver configured to receive signals from roadside equipment (RSE), including RSE associated with a traffic signal; and
braking sensors for the primary vehicle configured to detect when brakes of the primary vehicle are engaged;
wherein the transmitter is configured to transmit information regarding the braking status of the primary vehicle, and whether the brakes were engaged in response to the traffic signal; and
wherein the secondary vehicle control module is configured to notify the driver of the secondary vehicle of the hazard when the braking sensors of the primary vehicle detect that the brakes of the primary vehicle have been engaged to bring the primary vehicle to a stop that is not in response to the traffic signal.

14. A method for warning vehicles of hazards comprising:
-
detecting a hazard using hazard detection sensors of a primary vehicle; transmitting information regarding the hazard and a path history of the primary vehicle from a primary transmitter of the primary vehicle; receiving the information regarding the hazard with a secondary receiver of a secondary vehicle; notifying a driver of the secondary vehicle of the hazard when the secondary vehicle is traveling along a path similar to that of the primary vehicle; wherein the hazard includes at least one of a vehicle collision, disabled vehicle, traffic, and hazardous road conditions; relaying information regarding the hazard and the path history of the primary vehicle to the secondary vehicle by way of a transmitter/receiver of an intermediate vehicle; transmitting speed and location information of the intermediate vehicle from the transmitter/receiver of the intermediate vehicle to the secondary receiver of the secondary vehicle; calculating a minimum stopping distance for the secondary vehicle relative to the intermediate vehicle when the intermediate vehicle is stopped; and notifying the driver of the secondary vehicle when the secondary vehicle has reached the minimum stopping distance for the secondary vehicle. - View Dependent Claims (15, 16, 17, 18)
