USING V2X-BASED IN-NETWORK MESSAGE GENERATION, AGGREGATION, DISTRIBUTION AND PROCESSING PROTOCOLS TO ENABLE ROAD HAZARD CONDITION WARNING APPLICATIONS
First Claim
1. A method for detecting potentially hazardous road conditions, said method comprising:
- detecting a road condition by sensors on a plurality of vehicles around the road condition where each vehicle detecting the road condition assigns the detected road condition a confidence value;
transmitting the confidence value of the road condition from each vehicle that detects the road condition to other vehicles around the road condition;
aggregating the confidence values in one or more of the plurality of vehicles to generate an aggregated result that identifies the probability that the road condition is occurring; and
wirelessly transmitting the aggregated result to vehicles approaching the road condition.

Abstract
A method for providing messages indicating potential hazardous road conditions using a wireless communications network. Vehicles using the network include sensors that are able to detect various potentially hazardous road conditions, such as rain, fog, icy road conditions, traffic congestion, etc. A plurality of vehicles that detect a specific road condition provide a confidence value that the condition exists. The confidence value is then aggregated by the vehicles with the confidence value of the detected condition from the other vehicles to provide an aggregated result that identifies the probability that the detected road condition is occurring. The aggregated result is then transmitted to other vehicles approaching the road condition, possibly in a multi-hop manner. Alternately, the confidence value from all of the vehicles that detect the condition can be transmitted to approaching vehicles who will provide the aggregated result identifying the potential that the condition exists.

11. A method for detecting potentially hazardous road conditions, said method comprising:
-
detecting a road condition by sensors on a plurality of vehicles around the road condition where each vehicle detecting the road condition assigns the detected road condition a confidence value; transmitting the confidence value of the road condition from each vehicle that detects the road condition to other vehicles; aggregating the confidence value in one or more vehicles to generate an aggregated result that identifies the probability that the road condition is occurring; and causing a vehicle to act on the road condition if the aggregated result exceeds a predetermined threshold. - View Dependent Claims (12, 13, 14, 15, 16, 17)
