Inter-vehicle point-to-point communication method, device and system and storage medium

Abstract

The invention provides an inter-vehicle point-to-point communication method, device and system and a storage medium, and the method comprises the steps of enabling a main vehicle to obtain a first message from at least one first vehicle, wherein the first message comprises the identification information of the first vehicle and the position and azimuth information of the first vehicle; and determining a second vehicle from the at least one first vehicle based on the obtained position and orientation information of each first vehicle, and carrying identification information of the second vehicle and the first information in a second message for sending. Therefore, when the second vehicle detects that the identification information of the second vehicle carried by the second message is consistent with the identification information of the second vehicle, the first information is obtained from the second message. Namely, the main vehicle carries the identification information of the second vehicle and the to-be-sent first information in the second message and sends the second message to the second vehicle, the second vehicle can obtain the first information sent by the main vehicle, other vehicles cannot obtain the first information, and point-to-point communication between the main vehicle and the second vehicle is achieved.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular to a point-to-point communication method, device, system and storage medium between vehicles. Background technique [0002] Vehicle to everything (V2X) is to provide vehicle information through sensors and vehicle terminals mounted on the vehicle, and realize vehicle-to-vehicle (V2V) and vehicle-to-road communication through various communication technologies. (Vehicle to Infrastructure, V2I), between vehicles and people (Vehicle to Pedestrian, V2P), between vehicles and networks (Vehicle to Network, V2N) mutual communication. [0003] At present, the interaction between cars can adopt the car-cloud-car approach. The vehicle first transmits its own information to the cloud server through the Internet, and then the cloud server transmits it to other vehicles, thereby indirectly realizing the vehicle-to-vehicle interaction. [0004] However, in the above inter...

Problems solved by technology

[0004] However, in the above interaction method, the vehicle first needs to register the vehicle information with the cloud server, and when the information between vehicles is transferred through the cloud server, the quality of information interaction depends on the quality of the Internet connected to the vehicle, and the delay is relatively large.
