From the perspective of the current internet of vehicles, V2X has broad and narrow meanings, V2X is a general name of all networks connected to automobiles, V2X is a low-delay, highly reliable over-the-horizon communication technology, and V2X has the technical characteristics that: the over-the-horizon sensor is a technology for realizing perception through a radio wave propagation mode. X in V2X is variable, it can be replaced with V, I, P and N, etc., i.e., car and car (V2V), car and infrastructure (V2I), car and pedestrian (V2P), car and internet (V2N), etc.
V2X is the necessary technology for automatic driving of the automobile, can compensate the intelligent soft rib of a single automobile, and is the most important component for automatic driving. V2X is a communication technology that is not affected by weather conditions, as compared to vehicle-mounted sensors. For example, in sand weather or heavy rain or heavy fog, the action of the vehicle-mounted camera is weakened, but the V2X still can work normally, can pass through barriers without dead angles to acquire information, and forms interconnection and information intercommunication with the vehicle running environment, and meanwhile, the intelligent capacity can be acquired through a large remote platform to finish automatic driving.
