Abstract

The invention provides an inter-vehicle communication method and device, used for solving the problem that a traffic accident happens easily due to the fact that the communication performance of a dedicated short-range communication DSRC technology can be suddenly decreased possibly when vehicle nodes in a congestion road section is relatively dense. The method disclosed by the invention comprises the following steps of: obtaining driving information of a target vehicle in the road, wherein the driving information includes the number of adjacent vehicles of the target vehicle and / or the communication quality parameters of the target vehicle and the adjacent vehicles; and a data transmission channel between the target vehicle and the adjacent vehicle is established through a vehicular Ad Hoc network; and, if determining that the road, in which the target vehicle is, is the congestion road section according to the driving information of the target vehicle, switching the data transmission channel between the target vehicle and the adjacent vehicles into the data transmission channel between the target vehicle and the adjacent vehicles established by a mobile communication system. When the communication performance of the DSRC is relatively poor, DSRC communication resources are preferentially distributed to vehicles having relatively rapid speeds; and thus, the problem that the communication performance of the DSRC in the congestion road section is poor can be solved.

Description

Technical field [0001] The present invention relates to the technical field of communication applications, in particular to a method and device for inter-vehicle communication. Background technique [0002] The existing technical solution provides a technical solution for workshop communication between vehicle-mounted units through dedicated short-range communication technology DSRC (Dedicated Short Range Communication). However, on a road section with dense vehicle nodes, DSRC communication performance will drop sharply. For example, when the number of vehicles is 50, the packet loss rate exceeds 30%. However, congested road sections (such as crossroads) are areas where traffic accidents frequently occur. Summary of the invention [0003] The purpose of the present invention is to provide a method and device for inter-vehicle communication, which is used to solve the problem that the vehicle nodes on the congested road section are dense, and the communication performance of the ...
