Automatic relocation of AUTOSAR components among several ECUs

Abstract

Today, embedded systems are more and more involved in the definition of new and emergent functionalities of the vehicles and are developed by different component providers. This heterogeneity of origins complicates the integration and the validation of such systems. The standard AUTOSAR has been introduced to address this problem with the use, and reuse, of software components. But during the development phases, the AUTOSAR system architecture is often modified due to scheduling constraints, optimization or evolution and has to be manually maintained by the designer. During these different phases, software components are manually exchanged between different control units and these actions are error prone and time-consuming. The objective of this paper is to propose a method to automatically maintain the AUTOSAR architecture by providing a model transformation when a software component needs to be relocated from an ECU to another one.
