First Claim
1. A method for exchanging vehicle information between a plurality of moving vehicles, the method comprising:
- (a) creating one or more broadcasting groups, where each group represents one or more of said plurality of moving vehicles;
(b) forming one or more neighborhoods, each representing two or more vehicles from said one or more broadcasting groups;
(c) transmitting information about a first vehicle in a first of said one or more neighborhoods to at least one or more different vehicles from said one or more moving broadcasting groups; and
(d) using said transmitted information at one or more vehicles, if any, located within said first neighborhood.

Abstract
Methods and systems for vehicle-to-vehicle communications where vehicles can communicate one or more of speed, position, direction, acceleration and state in order to coordinate or control their operation are disclosed herein. In some embodiments of the disclosed subject matter, methods for vehicle-to-vehicle communications where vehicles can communicate one or more of speed, position and state in order to coordinate or control their operation. An exemplary method includes creating moving broadcasting groups which groups can move with the flow of traffic, adjust the span of the group and maintain minimum overlap size between adjacent broadcasting groups, combining two or more vehicles within one or more broadcasting groups, within some specified distance into neighborhoods, transmitting information about one or more of speed, position and state of vehicles in the neighborhood to the other vehicles in said neighborhood; receiving information about speed, position and state by vehicles in the neighborhood from the other vehicles in said neighborhood, filtering out duplicate information and information received from vehicles that are not in the same neighborhood, providing that two or more vehicles in the same neighborhood have substantially continuous communication capacity by maintaining the size of overlap between adjacent neighborhoods, avoiding delays in entering the new neighborhood by extending the overlap size, and utilizing one or more guarantees provided by an underlying reliable broadcast communication layer by transferring said guarantees to corresponding one or more neighborhoods.

10. A system for exchanging vehicle information between a plurality of moving vehicles, the system comprising:
a processing unit adapted to be operatively coupled to a first vehicle, a wireless connection device operatively coupled to said processing unit, at least one sensor, operatively coupled to said processing unit, for sensing information about said first vehicle, and a memory operatively coupled to said processor unit and storing program instructions that when executed by said processor, cause said processor to; (a) create one or more broadcasting groups, where each group represents one or more of said plurality of moving vehicles, including said first vehicle; (b) form one or more neighborhoods, each representing two or more vehicles from said one or more broadcasting groups, wherein at least a first of said one or more neighborhoods represents vehicles which include said first vehicle; and (c) transmit information using said wireless connection device about a said first vehicle in said first neighborhood to one or more different vehicles from said one or more moving broadcasting groups. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A system for exchanging vehicle information between a plurality of moving vehicles, the system comprising:
-
(a) means for creating one or more moving broadcasting groups, where each group represents one or more of said plurality of moving vehicles including a first vehicle; (b) means, coupled to said creating means, for forming one or more neighborhoods, each representing two or more vehicles from said one or more broadcasting groups, wherein at least a first of said one or more neighborhoods represents vehicles which include said first vehicle; and (c) means, coupled to said forming means, for sensing information about said first vehicle and means, coupled to said sensing means, for transmitting in said first neighborhood to one or more different vehicles from said one or more moving broadcasting groups. - View Dependent Claims (18, 19, 20)
