Vehicle-mounted network communication method for service-oriented architecture

Abstract

The invention provides a vehicle-mounted network communication method for a service-oriented architecture, and the method comprises a basic sensing layer which is used for receiving data collected by external equipment; the basic service layer is used for receiving the data from the basic sensing layer, analyzing the data and converting the data into corresponding services; and the combined service layer is used for receiving the service provided by the basic service layer, processing a service calling algorithm and issuing a corresponding service request to the basic service layer according to a processing result. In the technical scheme provided by the invention, hierarchical management and control are provided. Each layer realizes a specific function, the combined service layer provides upper-layer function services, high-order function services are realized in the combined service layer, bottom-layer service processing is realized in the basic service layer, and multiple times of transmission of information generated by multiple times of calling among services among the services among vehicle-mounted networks is avoided.

Description

technical field [0001] The invention relates to the field of vehicle network communication, in particular to a method for vehicle network communication of a service-oriented architecture. Background technique [0002] The changes in the demand for vehicles in modern society have prompted us to continuously improve the performance, safety and comfort of vehicle communication networks. As a result, more and more ECUs are integrated in modern vehicles, which greatly increases its structural complexity and Cost of production. The ECUs in the car are connected through a dedicated communication bus. The automotive industry has used the CAN bus as a cost-effective solution since the 1980s. However, the old bus technology is more and more unable to meet the increasing bandwidth demand for bandwidth, so the vehicle Ethernet technology emerges as the times require, which provides a bandwidth of up to 1000Mbit / s and can greatly reduce costs; in addition, using Ethernet And based on ...

Problems solved by technology

However, the old bus technology is more and more unable to meet the increasing bandwidth demand for bandwidth, so the vehicle Ethernet technology emerges as the times require, which provides a bandwidth of up to 1000Mbit / s and can greatly reduce costs; in addition, using Ethernet And based on its upper layer protocol, we can integrate traffic types using different communication protocols into a common backbone network with better compatibility

The introduction of in-vehicle Ethernet has changed the communication protocol. TCP / IP adopts SOME / IP based communication according to the standard. Although the communication method of SOME / IP protocol has many advantages, there are so many ECUs in smart cars and The realization of different functions in each ECU and the frequent mutual calls of services cause competition among services. The limited network resources and system resources pose a challenge to real-time and reliable communication in the vehicle.
