On-ground vehicle collision avoidance utilizing shared vehicle hazard sensor data
First Claim
1. An on-ground collision avoidance system, the system comprising:
- a ground based hazard data aggregation system comprising at least one memory storing a hazard position database; and
at least one vehicle-ground communications electronics system coupled to the ground based hazard data aggregation system;
wherein the ground based hazard data aggregation system is communicatively coupled to an onboard ground hazard collision avoidance system of at least a first on-ground subscriber vehicle through a wireless datalink established via the vehicle-ground communications electronics system;
wherein the hazard position database stores vehicle collected hazard position data generated by a first on-ground contributing vehicle, wherein the first on-ground contributing vehicle collects hazard position data about on-ground hazards detected by at least the first on-ground contributing vehicle using a vehicle mounted object detection sensor; and
wherein the ground based hazard data aggregation system transmits to the first on-ground subscriber vehicle aggregated hazard position data from the hazard position database, the aggregated hazard position data including the vehicle collected hazard position data generated by the first on-ground contributing vehicle.

18. A method for on-ground collision avoidance, the method comprising:
-
establishing a first wireless communication link between a ground based hazard data aggregation system and one or more hazard data contributing vehicles equipped with a vehicle-ground communications electronics system; receiving at the ground based hazard data aggregation system vehicle collected hazard position data via a downlink from the one or more hazard data contributing vehicles, wherein the vehicle collected hazard position data comprises hazard position data collected for on-ground hazards detected by the one or more on-ground contributing vehicles using a vehicle mounted object detection sensor; receiving at the ground based hazard data aggregation system baseline hazard position data from one or more ground based hazard detection systems; and combining the vehicle detected hazard position data with the baseline hazard position data in a hazard position database; establishing a second wireless communication link between a ground based hazard data aggregation system and one or more hazard data subscriber vehicles with the vehicle-ground communications electronics system; transmitting aggregated hazard position data from the hazard position database as an uplink to the one or more hazard data subscriber vehicles. - View Dependent Claims (19, 20)
