Abstract
Device, system and method, in a vehicle communication system, to transmit wirelessly the position, heading and speed of a vehicle or other moving object. In a key embodiment the vehicle is other than the transmitting vehicle. Some embodiment use local sensors on a first vehicle, such as cameras, sonar, radar or LIDAR to identify the relative position, heading and speed of a second vehicle relative to the first, transmitting, vehicle. An embodiment uses the location of the vehicle whose information is being transmitted as the identification of the same vehicle. Embodiments also receive these messages. Embodiments use this information as warning and safety information to avoid or minimize vehicle collisions. A unique feature of some embodiments is that the messages are free of IP and MAC addresses.

16. A vehicle-to-vehicle (V2V) communication system comprising:
-
a basic time interval, of predetermined length, which repeats continuously;
wherein the basic time interval is comprised of predetermined, consecutive, enumerated timeslots;a plurality of vehicles, each equipped with an associated V2V transponder; wherein a first vehicle with a first V2V transponder is configured to accept as input the first vehicle'"'"'s position and heading; and
the first V2V transponder uses a first protocol to obtain a first transmit timeslot; and
the first V2V transponder broadcasts real-time vehicle information for the first vehicle in the first transmit timeslot, repetitively, once per basic time interval;a non-equipped second vehicle, free of a compatible V2V transponder; vehicle sensors located on the first vehicle, wherein the vehicle sensors identify the relative position of the second vehicle from the first vehicle; wherein the first V2V transponder broadcasts real-time vehicle information for the second vehicle, repetitively, once per basic time interval; wherein the broadcasts information for the second vehicle is marked as a proxy message; wherein the V2V communication system does not require fixed location, road-side units. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method of communicating vehicle-to-vehicle comprising:
-
repeating continuously a basic time interval, wherein the basic time interval is comprised of predetermined, consecutive, enumerated timeslots; accepting as input a first vehicle'"'"'s position and heading to a V2V transponder associated with the first vehicle;
wherein the V2V transponder is not dependent on communication from fixed infrastructure;using a first protocol by the V2V transponder to obtain a first timeslot; broadcasting messages in the first timeslot repetitively in each basic time interval;
wherein at least one message comprises real-time information about the first vehicle;accepting as input a second vehicle'"'"'s position relative to the first vehicle to the V2V transponder; broadcasting a message comprising information about the second vehicle. - View Dependent Claims (35)
