The car networking senses the state information of the vehicles by using a sensing technology, and realizes intelligent management of traffic, intelligent decision of traffic information service and intelligent control of the vehicles by using a wireless communication network and a modern intelligent information processing technology.
The current Internet of vehicles service platform adopts cloud computing technology, covers multiple layers of systems, networks, applications and the like, and is operated by professional teams. The function of the car networking service platform is gradually strengthened, the car networking service platform becomes a core platform integrating data acquisition and function control, various types of safety cloud services are deployed, and intelligent network connection car safety management is strengthened.
In the internet of vehicles construction, the vehicle data access cloud platform is the important content (namely, V2N implementation).
