Communication link, so that every chassis all establishes with other vehicle and directly links topology.All can lead between every chassis
Cross car border DCL to communicate, when due to the link failure reason direct link that causes communicating between certain two car obstructed
Time, flow of information, according to the routing iinformation of this car to purpose vehicle, is mail to, from this car, next car that routing table is specified by source vehicle
On, next car according to the routing table routing iinformation of self, is forwarded to next car that routing table is specified again again, until it reaches
Till purpose vehicle, thus realize the communication between source vehicle and purpose vehicle.
In conjunction with Fig. 5 it can be seen that described 4th vehicle-to-vehicle communication system tree topology framework, being divided into 4 layers, top is root joint
Point, only comprises vehicle 1；Its next layer is the 1st level of child nodes, comprises vehicle 11 until vehicle 1n；Next layer is the 2nd straton joint again
Point layer, comprise the vehicle 21 of the lower level of child nodes of vehicle 11 until vehicle 2n, vehicle 1n lower level of child nodes vehicle 2m until
The lower level of child nodes vehicle of the vehicle of vehicle 2m+n and other the 1st level of child nodes；Last 1 layer is the 3rd layer of leaf node, comprises car
The vehicle 31 of the lower level of child nodes of 21 until vehicle 3n, vehicle 2n the vehicle 3m of lower level of child nodes until vehicle 3m+n, car
The vehicle 3p of the lower level of child nodes of 2m until vehicle 3p+n, vehicle 2m+n the vehicle 3q of lower level of child nodes until vehicle 3q+n
And the lower level of child nodes vehicle of the vehicle of other the 2nd level of child nodes；Vehicle 1 as the root node vehicle of whole communication system, its
The 1st communication link set up by 1st radio equipment and vehicle 11, the 2nd radio equipment to the (n+1)th radio equipment of vehicle 11 respectively with
1st radio equipment of vehicle 21 to vehicle 2n sets up n communication link, and the 2nd radio equipment of vehicle 21 is to the (n+1)th radio equipment
The 1st radio equipment with vehicle 31 to vehicle 3n sets up n communication link respectively, until the 2nd radio equipment of vehicle 2n is to n-th
+ 1 radio equipment the 1st radio equipment with vehicle 3m to vehicle 3m+n respectively sets up n communication link, completes the 1st article of vehicle 1
The whole network of communication link；Until the n-th radio equipment of vehicle 1 and vehicle 1n set up nth bar communication link, the of vehicle 1n
2 radio equipments to the (n+1)th radio equipment the 1st radio equipment with vehicle 2m to vehicle 2m+n respectively sets up n communication link, car
2nd radio equipment to the (n+1)th radio equipment of 2m the 1st radio equipment with vehicle 3p to vehicle 3p+n respectively is set up n article and is led to
Letter link, until the 2nd radio equipment to the (n+1)th radio equipment of vehicle 2m+n respectively with the 1st of vehicle 3q to vehicle 3q+n letter
Road equipment sets up n communication link.Often led to by car border DCL between chassis and the vehicle of adjacent connection
Letter, communicates with between the non-adjacent vehicle being connected, and flow of information mails to next car that routing table is specified from this car, next car
Again according to the routing table routing iinformation of self, again it is forwarded to next car that routing table is specified, until it reaches purpose vehicle is
Stop, thus realize the communication between source vehicle and purpose vehicle.
In conjunction with Fig. 6 it can be seen that described 5th vehicle-to-vehicle communication system mixed type topology framework, open up serial topology framework
Flutter (1), ring topology framework subtopology (2), mesh topology framework subtopology (3) and tree topology framework subtopology (4) mixing
Connect and compose, vehicle 1 in mesh topology framework subtopology (3), vehicle 2, vehicle 3 respectively with serial topology framework subtopology
(1) 7 points of root node vehicle in vehicle 6, tree topology framework subtopology (4) in vehicle 5, ring topology framework subtopology (2) in
Do not build communication link.Often communicated by car border DCL between chassis and the vehicle of adjacent connection, with non-
Between the vehicle of adjacent connection, if source vehicle and purpose vehicle are in same subtopology, its communication process is with reference to corresponding
Single topology framework, if source vehicle and purpose vehicle be not in same subtopology, communication data stream needs to cross over subtopology
Time, then flow of information mails to the vehicle of subtopology at connection purpose vehicle place self place subtopology from source vehicle, then
Be forwarded in purpose subtopology by this vehicle again, the data stream of follow-up forwarding with reference to corresponding single topology framework,
Thus realize the communication between source vehicle and purpose vehicle.
