And the tailstock, both mutually judge matching, and OBU coordinates Y vehicle is corresponded with ground sense vehicle one by one to be matched, and feels vehicle with learning
In first vehicle be OBU or non-OBU vehicles, second vehicle, the 3rd vehicle, and match OBU's by each successively
Ground sense vehicle assignment vehicle, terminates until matching all vehicles, forms track vehicle platoon transaction system.Match parameter is felt for ground
Each real-time physical location, set up the legal area of the virtual elements of a fix, depending on each legal area is according to antenna positioning precision, now recognize
For sum of each position positioning precision felt for+- 1m and ground sense width value itself.
Fabs(YGround sense N-YRSU)≤Para_Dis,
Wherein, Para_Dis ∈ (feel m 0+N, felt m) 1+N.
Above-mentioned condition is met, then can clearly know that track is present without OBU vehicles, forbid transaction, closes scanning phased array day
Line, waits this to sail out of track without OBU vehicles, and real-time update feel vehicle platoon and electronic tag queue.
In process of exchange, phased array antenna has three wave beams, by triggering antenna mode, and system controls antenna, i.e.,
When vehicle is felt with driving to triggering, antenna is opened, aerial signal is at this moment irradiated to far field end, real-time tracking vehicle, vehicle pressure
When feeling to the position of middle petiolarea, it is assumed that feel for No. 3 positions, aerial signal now is irradiated into middle area end, vehicle is pressed onto closely
When feeling, it is assumed that feel for No. 5 positions, aerial signal now is irradiated near region end, so as to be both tracking vehicle, again end position
Control separates OBU signals of vehicles, then by calculating OBU vehicle coordinates with the location algorithm of phased array, is flexibly matched with, matched
Transaction is just set up in success, is otherwise abandoned information, is re-searched for.
The present embodiment obtains the ground sense of all vehicles by forming electronic tag queue, the ground sense change that vehicle is passed through
Positional information, feels queue with setting up vehicle, according to electronic tag queue and vehicle platoon according to effectively judgement, can obtain whole
The preliminary information of all vehicles is in queue：There are the coordinate of OBU vehicles, the position of no OBU vehicles.So as to just can really solve
Certainly lie is disturbed, and no OBU vehicles are rushed by mistake, front and rear OBU vehicles crossing of orders, and with car interference, so that causes can not move backward
