Definition of V2X

Vehicle to Everything (V2X) is a new generation of information and communication technology that connects vehicles to everything. V represents vehicles and X represents any object interacting with the vehicle. At present, X mainly includes vehicles, people, roadside infrastructure, and network. The information modes of V2X interaction include Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), Vehicle to Pedestrian (V2P), Vehicle to Network (V2N).

V2X technologies defined by 3GPP include V2V, V2I, V2P, V2N/ V2C and other communication scenarios. Autonomous driving security leader, AUTOCRYPT, announced that its V2X security solution, #auto Crypt V2X, now implements YD/T 3957-2021, the newest standard for LTE-based V2N communications and credential managemen.  

V2X uses various wireless communication technologies to connect traffic participation factors such as vehicle, road, people, cloud, etc. V2X can not only enable vehicles to obtain more perceptual information, but also promotes the innovation and application of autonomous driving technology. It is also beneficial to the construct the intelligent traffic system. It can promote the development of new models and new formats of vehicles and traffic services. And it is significant in improving traffic efficiency, saving resources, reducing pollution, reducing the frequency of accidents, and improving traffic management.

Vehicle to Vehicle (V2V)

Vehicle to Vehicle (V2V) is used for vehicle-mounted communication. The most common application scenario is in urban streets and expressways. Vehicles communicate with each other, send data, realize information and data sharing in that case.

The intelligent vehicle computing #platform can send or receive the following data: speed, the relative position, braking, orientation, and all data related to safety. It can even take pictures, audio, or video of things around. Then, it analyzes and forecasts other vehicles’ driving behavior. Doing so can achieve active security strategy, improve road safety, and provide data points for semi-automatic and automatic driving.

V2V technology allows vehicles to prevent accidents by relaying real-time information about themselves and the road ahead. It can reduce commuting time, and ultimately improve the traffic environment and reduce traffic congestion.

V2V vehicle communication can achieve vehicle-to-vehicle communication through D2D protocol in C-V2X. It brings another operation and maintenance mode for OEMs. Namely, it can effectively establish intelligent fleets, plan route, reduce fuel consumption, and improve operating income.
