A Realization Method of Autosar Software Architecture

Abstract

The invention provides an implementation method of AUTOSAR software architecture, which belongs to the field of vehicle network technology, including: generating data management files from original data protocols and original simulation modules; performing data matching detection on data management files; generating AUTOSAR software configurations from data management files Architecture file; import the configuration architecture file into the RTE configuration tool to configure the system of the AUTOSAR software and obtain a first system configuration file, and generate an application architecture model of the AUTOSAR software according to the configuration architecture file. Beneficial effects of the present invention: can realize the unified management and control of RTE, avoid the input and output mismatch problem of each software control module; software control module developers can continue the traditional module development mode, and can ignore the existence of AUTOSAR; it is beneficial to the automatic realization of AUTOSAR architecture , improve development efficiency; without supporting a series of automatic development tools, realize AUTOSAR configuration efficiently.

Description

technical field [0001] The invention relates to the technical field of vehicle networks, in particular to an AUTOSAR software architecture implementation method. Background technique [0002] AUTOmotive Open System Architecture (AUTOSAR) is a developed and standardized automotive software architecture, which mainly consists of Application layer (Applincation layer), Run Time Environment (RTE), Service Operating System layer (Basic Software layer, BSW). layer) and electronic control unit hardware (Electronic Control Unit hardware, ECU hardware). [0003] Among them, there are many mainstream suppliers of BSW layer and RTE that can provide more mature solutions, such as Vector, ETAS, Mentor, etc., and domestic ones include Puhua software. Most of these suppliers' solutions can support AUTOSAR 4.1.3 and above, which basically meet the current domestic development needs for AUTOSAR. Of course, AUTOSAR software packages and supporting tools are relatively expensive, and it is d...

Problems solved by technology

The disadvantage of this method is that it must be equipped with a series of automated development tools, otherwise AUTOSAR configuration will be a task that cannot be completed manually

[0010] The "bottom-up" method has many shortcomings in the actual implementation process: 1. Each module must first define the module input (inport), output (outport), input interface (input interface), and output interface (outputinterface) , runnable, event and other attributes, for an iterative development system, the input and output will actually change constantly, in a distributed development system, this will bring disaster to AUTOSAR software integration As a result, the direct input and output mismatch of each module will cause the system to fail to integrate, and enter an infinite loop of integration-module update-integration-module update, which greatly reduces the workload and maintenance difficulty; 2. In the distributed development system, this The method has high requirements for module developers, who must master SWC methodology and configuration methods, or ASW needs to add full-time AUTOSAR architecture control or maintenance personnel, which will lead to increased ASW development costs
