Enhancing AUTOSAR methodology to a cotsbased development process via mapping to V-Model

Abstract

AUTOSAR, an open standard for automotive software, is currently being exploited by the automotive industry. Although the standard mainly focuses on software architecture, it also provides a development methodology. Unfortunately, the methodology in its current form is insufficient for industrial exploitation because it describes only an incomplete set of activities, work products and their dependencies. Specifically, (1) the activities to support COTS-based development are missing even though AUTOSAR encourages the use of COTS components; (2) it does not describe the roles and their responsibilities; and (3) it does not specify the mapping of activities onto a complete process model. In this paper, we propose a new software development process for AUTOSAR by extending the existing methodology. In doing so, we add activities to allow COTS component selection, evaluation and integration. Then, we define specific roles and assign responsibilities to those roles. Finally, we describe the overall timeline of various activities in detail by mapping the activities to the V-model. In order to present the process, we have used SPEM 2.0 notation, which is backward compatible with the AUTOSAR methodology and has improved expressiveness. We have composed the proposed process model using Eclipse Process Framework Composer which not only performs a sanity check of the model but also provides a way to publish it.
