Seriously, especially legal festivals and holidays and peak time morning and evening.On the other hand, frequent traffic thing cause serious personal's injures and deaths and
Property loss.Intelligent network joins automobile to play an important roll in terms of improving traffic safety and improving traffic efficiency, and helps to save
It can environmental protection.Intelligent network connection automobile refers to carrying the devices such as advanced onboard sensor, controller, actuator, and merge modern logical
Letter and network technology realize that vehicle exchanges with X (vehicle, road, people, cloud etc.) intelligent information, is shared, have complex environment perception, intelligence
The functions such as decision, Collaborative Control finally realize that substitute people new come what is operated, it can be achieved that safe efficient, comfortable, energy saving traveling
Generation automobile.It perceives vehicle-surroundings environment by Information and Communication Technology, and can be carried out to surrounding vehicles Future movement
Prediction, and then driver behavior auxiliary is carried out to driver.More even, estimate according to expert, the mankind will be prohibited to drive after 25 years
The ultimate aim of vehicle, intelligent network connection automobile is that realization is comprehensively unmanned.In foreseeable future, driver will the no longer side of holding
To disk and control stick, but mobile office can be carried out in the car or enjoys relatively rich media entertainment.
In order to which intelligent network joins automotive engineering so that finally realizing unmanned, three steps are essential, i.e. " perception-
Decision-execution ".And " perception " is also a most key step as the first step, the traffic environment being around perceiving, to for
The decision of vehicle and the data that offer magnanimity is provided.However, it is far from enough to rely solely on bicycle perception.Therefore, it to realize comprehensively
It is unmanned, it is necessary to vehicle be networked and be communicated, the moment keeps the information exchange with Adjacent vehicles.
It includes four aspects that intelligent network, which joins demand of the automobile to networking mainly,：First upload onboard sensor perceives
Various data, second is the real-time dynamic high precision 3D maps of update, and third is that video returns in real time, and the 4th is provided for passenger
The multimedia recreation of high speed is experienced.It will will produce and disappear it was predicted that the pilotless automobile of intelligent network connection often travels 8 hours
The data traffic of general 40TB is consumed, that is, rate needs to reach 11.38Gbps, in addition to the data of processing locality, it is assumed that about
There is 20% data volume to need to upload, it is also desirable to which the traffic rate of general 2.28Gpbs is supported.An only pilotless automobile
Demand to communication is just so big, is one serious for existing network if up to a hundred vehicles access network simultaneously
Challenge.For support of the current 4G networks to vehicle, upstream rate is about 75Mb/s, downstream rate about 300Mb/
S is far from the requirment.Even for upcoming 5G, user experience rate is also with regard to 0.1-1Gbps.So intelligent network
The communication requirement for joining automobile proposes stern challenge to existing communication network even upcoming 5G communication networks.
