Develpment of an integration method of model-based software with a standard software architecture

High complexity of automotive embedded software has caused an increase of software development time and costs in the automotive industry. In order to reduce the software development efforts, two software development methodologies have been introduced: the model-based software development process and standardization of software architecture. In this paper, we proposed a methodology to integrate the model-based software development procedure with the in-house software architecture. First of all, we introduced a software architecture which contains important features and advantages of the AUTOSAR. Based on the proposed architecture, following important software models such as software components, runnables, and interfaces were modeled using MATLAB/Simulink. From the software models, c-codes were generated using an auto-code generation tool and a method for integrating the generated code into the automotive embedded software was proposed. In order to verify the feasibility of the proposed integration method, we applied this software development methodology to a motorcycle engine management system
