Problems solved by technology

Due to the good compatibility of Matlab / Simulink in modeling, code generation and AUTOSAR version, after designing the software architecture, if Simulink is used to model the internal behavior, there will be a problem of synchronization between the AUTOSAR model and the Simulink model
Moreover, for software components (Software Component, SWC), in most cases, it is difficult to ensure that all software component information is designed once. Automotive electronics development is an iterative process. In this case, subsequent AUTOSAR tools and When interacting with Simulink, the mdl model cannot be recreated, but the model modification operations made by the application engineer need to be synchronized to the Simulink model file. Therefore, there is an urgent need for a fast and efficient method for comparing and synchronizing the AUTOSAR model to the Simulink model

Abstract

The invention discloses a method for synchronizing an AUTOSAR (automotive open system architecture) model to a Simulink model. The method includes: using an ARXML (AUTOSAR extensible markup language) source file to generate the AUTOSAR model, analyzing AUTOSAR object elements to obtain elements of the model, mapping the obtained elements of the AUTOSAR software module into the Simulink model to obtain a corresponding model port label set, and loading by means of HashMap; accessing to a generated folder of the Simulink model to search a journal file generated last time, and analyzing the journal file to obtain a corresponding Simulink model port label set of an MATLAB (matrix laboratory) / Simulink model; and comparing the obtained NEW label set with an OLD label set to obtain a result pool, and realizing model synchronization by means of Matlab orders. The method for synchronizing the AUTOSAR model to the Simulink model has the advantages of simplicity and convenience in conversion, low time consumption and low development cost.

Description

technical field [0001] The invention relates to data synchronization technology, in particular to a method for synchronizing an AUTOSAR model to a Simulink model.
