what is V2X
Nov 01, 2018

    V2X is the key to realizing this idea. It refers to the exchange of information between the car and the outside world. It is a general term for a series of in-vehicle communication technologies. It uses radio frequency identification (RFID), sensors, and cameras mounted on the vehicle to obtain vehicle driving conditions, system operating status, and surrounding road environment information. At the same time, GPS location is used to obtain vehicle location information, and these information are forwarded through D2D technology. The transmission of the peer end, in turn, enables the sharing of information throughout the vehicle networking system. Through the analysis and processing of these information, the driver can report the road condition and warning in time, effectively avoiding the congestion road section and selecting the best driving route.

 V2X and T-Box

   V2X generally includes five types: vehicle-to-vehicle (V2V), vehicle-to-road (V2R), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N).

   V2V (Vehicle to vehicle) enables information exchange between vehicles. The most typical application is to prevent various vehicle collisions, collisions and rear-end collisions.

   The V2R (Vehicle to roadside unit) is developed through a millimeter-wave radar and a camera. It also supports high-precision maps and cloud support. It is mainly divided into two scenarios, the first is the highway and the second is the urban road.

   V2I (Vehicle to infrastructure) enables vehicles to exchange data with roads and roadside infrastructure, such as traffic lights, various road signage information, and more.

   V2P (Vehicle to pedestrian, car and pedestrian) mainly realizes the function of protecting pedestrians and non-motor vehicles. Vehicles have many ways to detect pedestrians. In addition to relatively intuitive cameras and various sensors, information interconnection is also the most effective method.

   V2N (Vehicle to network) enables vehicles to connect to servers in the cloud via a mobile network, enabling navigation, entertainment, security and other application functions.
