V2V SAFETY SYSTEM USING SELF-GENERATED LANE MAPS
First Claim
1. A vehicle-to-vehicle (V2V) communication transponder adapted to operate in a first vehicle wherein the transponder is adapted to accept as input a first location of the first vehicle and a vehicle heading of the first vehicle, and wherein the transponder is adapted to broadcast a series of V2V safety messages wherein a majority of V2V safety messages comprise:
- (i) the first vehicle position;
(ii) the first vehicle heading; and
(iii) a first vehicle speed; and
wherein the transponder comprises a lane map data store in non-transitory memory;
wherein the improvement is;
the lane map data store further comprises;
(i) a location point store comprising one or more location points, and (ii) a lane records store;
wherein the location point store comprises a plurality of locations contained in V2V safety messages received by or transmitted by the V2V communication transponder;
wherein the lane records store comprises one or more lane records and wherein each lane record comprises;
(i) a lane type, and (ii) location data that identifies the location of the lane.

Abstract
A vehicle-to-vehicle (V2V) communication transponder for use in V2V communication, safety and anti-collision systems incorporating a location point store and a lane records store, wherein the lane records are constructed by the transponder from the point in the location point store, location points are received from other moving transponders, and lane records are shared between transponder response to a request. Separate source counts are kept for internally generated and shared lane records. Methods of sharing are described. Lane types are also derived from the location point store and other vehicle behavior. No central authority, road-side equipment, (RSU), or pre-determined lane maps are required. Embodiments include a hybrid protocol using both TDMA and CSMA. Some embodiments are free of MAC and IP addresses. Embodiments include equipped vehicles and V2V system using the transponder.
