specific Embodiment approach 1

[0020] The specific embodiment one, is used for the point-to-point communication method of electric vehicle, and it comprises the following steps:

[0021] Step 1. Store the wireless network layout of each community and the historical data of the strength of various wireless networks in the control center, and list them in order from strong to weak;

[0022] Step 2. Within a time period, if an electric vehicle intends to initiate point-to-point communication, the electric vehicle is recorded as a node AP; then the electric vehicle sends a point-to-point communication request packet to the control center, and the point-to-point communication request packet includes: Self ID, ID of another communication party, longitude and latitude of current coordinates, business type to be communicated;

[0023] Step 3, the control center receives the communication request data packet, reads the ID of another communication party in the point-to-point communication request data packet, and sen...

specific Embodiment approach 2

[0035] Embodiment 2. The difference between this embodiment and the point-to-point communication method for electric vehicles described in Embodiment 1 is that in step ten, the control center sends the network distribution data packet to the initiating node and another communication node. Including: an alternative network; the initiating node and another communication node change the service type, and the two parties switch to the alternative network for point-to-point communication.

Abstract

The invention discloses a point-to-point communication method for an electric automobile, and relates to a point-to-point communication technology for an electric automobile. The invention aims to solve problems of low spectrum efficiency and poor communication reliability in the point-to-point communication process between an electric automobile and the outside world. In the invention, a control center selects an appropriate wireless network according to a service type reported by the electric automobile by combining the signal intensity of a cell where the electric automobile is located before the electric automobile performs point-to-point communication with the outside world, and communication with the electric automobile is performed in the selected wireless network. The two parties can perform point-to-point communication through an alternative network when the service type changes in the point-to-point communication process. The point-to-point communication method is high in spectrum efficiency, and the communication reliability is also greatly improved. The point-to-point communication method is applicable to point-to-point communication occasion of the electric automobile.

Description

technical field [0001] The present invention relates to point-to-point communication technology for electric vehicles. Background technique [0002] Electric vehicles, which use electricity as energy, are increasingly replacing traditional vehicles and becoming people's first choice. Electric vehicles are often equipped with wireless communication equipment for real-time and long-distance communication. [0003] As the number of electric vehicles increases, point-to-point communications between electric vehicles become more and more frequent, which leads to a shortage of spectrum resources and a decrease in communication efficiency; , due to the difference in signal conditions, the reliability of communication needs to be improved. Contents of the invention [0004] The invention aims to solve the problems of low frequency spectrum utilization rate and poor communication reliability in the point-to-point communication process outside the electric vehicle, thereby providi...
