Embodiment 1

[0040] The embodiment of the present invention establishes a cross-platform vehicle communication system with the enhanced DSRC communication protocol as the core.

[0041] When other devices actively send communication data to vehicles supporting the enhanced DSRC communication protocol, this embodiment provides a schematic diagram of the realization principle of a cross-platform vehicle communication method as shown in figure 1 As shown, the processing flow diagram is as follows figure 2 As shown, the following processing steps are included:

[0042] Step S210, setting an enhanced DSRC communication protocol unit and at least two single-protocol communication units in the vehicle, the enhanced DSRC communication protocol unit can handle communication data of at least two communication protocols, and the single-protocol communication unit can handle a single The communication data of the communication protocol.

[0043] The above-mentioned enhanced DSRC communication proto...

Embodiment 2

[0057] When a vehicle supporting the enhanced DSRC communication protocol actively sends communication data to other devices, this embodiment provides a schematic diagram of the implementation principle of a cross-platform vehicle communication method as shown in image 3 As shown, the processing flow diagram is as follows Figure 4 As shown, the following processing steps are included:

[0058] Step S410, the vehicle needs to communicate with multiple other devices in the device registry.

[0059] Step S420, the above-mentioned vehicle inquires the above-mentioned device registry in turn according to the identifiers of a plurality of other devices, and judges whether the above-mentioned other devices support the enhanced DSRC communication protocol, if yes, perform step S430; otherwise, perform step S440.

[0060] Step S430, when the other device supports the enhanced DSRC communication protocol, the vehicle communicates with the other device through the enhanced DSRC commun...

Abstract

The embodiment of the invention provides a cross-platform vehicle communication method and system. The method mainly comprises the following steps: arranging an enhanced DSRC (Dedicated Short Range Communication) communication protocol unit capable of processing communication data of at least two communication protocols and at least two single protocol communication units in a vehicle; when the vehicle communicates with other equipment, judging whether the other equipment supports an enhanced DSRC communication protocol, if so, communicating with the other equipment by the vehicle through the enhanced DSRC communication protocol unit, or else, selecting one single protocol communication unit supported by the other equipment to communicate with the other equipment by the vehicle. According to the cross-platform vehicle communication method and system, the traditional design thought of a vehicle communication system restricted to the DSRC communication protocol is changed, the extension of definition of the vehicle communication system is expanded, different communication functions are managed in a concentrating manner, the vehicle communication system is not restricted to a communication platform of the specific communication protocol and becomes a cross-platform communication system by taking the DSRC as a core, and the communication protocol supported by the other equipment can be flexibly selected to communicate with the other equipment.

Description

technical field [0001] The invention relates to the technical field of vehicle communication, in particular to a cross-platform vehicle communication method and system. Background technique [0002] The protocol layer of the national standard GB / T20851-2007 series standard is based on the DSRC (Dedicated Short Range Communications, dedicated short-range communication technology) technology with domestic independent intellectual property rights. DSRC technology uses 5.8GHz frequency as the working frequency. At the beginning of the application of DSRC technology, this technology was mainly used in the field of highway non-stop toll collection. With the increasing issuance of vehicle electronic tags, more and more vehicles have DSRC communication capabilities. Therefore, the demand for vehicle communication is gradually expanding, which will also become a key area for the development of intelligent transportation. [0003] The existing in-vehicle communication equipment has ...
