Lane mapping in a vehicle-to-vehicle communication system
First Claim
1. The vehicle-to-vehicle (V2V) communication system comprising:
- a V2V transceiver configured to transmit and receive V2V messages;
a lane map data store comprising lane map data stored in non-transitory memory;
wherein 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 previously contained in V2V messages received or transmitted by the V2V transceiver;
wherein the lane records store comprises one or more lane records and where each lane record comprises;
(i) a lane type, and (ii) one or more locations.

Abstract
Device, system and method, in a vehicle communication system, of generating lane maps. Embodiments use a plurality of location points to build up a lane, then record that lane in memory. Location points may be locations over which a first vehicle generating the lane map passes, or may be location points broadcast by a second vehicle to the first vehicle. Methods are described to wirelessly share lane information and lane maps between vehicles. Embodiments use a “confidence value” describing the confidence that the lane parameters are valid. Algorithms are described for creating and updating the confidence values. Methods of compressing and storing lane information and lane maps are described. Embodiments include geographic height in lane information.

17. A method of generating lane maps comprising:
-
generating local location points; storing the local location points in a location point store; counting the number of times a similar location point is generated, the “
local location count;
”storing the local location count; transmitting at least one of the local location points and the local location count; receiving a receive record comprising at least one candidate location point and a receive count; storing the at least one candidate location point and the receive count; comparing the at least one candidate location point to a prior stored location point; comparing the receive count to a prior stored location count when the at least one candidate location reasonably matches the prior stored location point; updating the prior stored location count if the receive count is greater than the prior stored location count to now equal the receive count.
