Communications-oriented development of component-based vehicular distributed embedded systems
Saad Mubeen · 2014
The model- and component-based development approach has emerged as an attractive option for the development of vehicular distributed embedded control systems. Within this context, we target the issues related to modeling of legacy communication; extraction of timing models; and support for End-to-end Response-time and Delay Analysis (ERDA). We propose a novel approach for modeling legacy network communication to support the state-of-the-practice development of these systems. Further, we present a method to extract end-to-end timing models to support the ERDA of these systems. We also take a step towards broadening the scope and usability of our techniques by extending the model extraction method at various abstraction levels. As part of the ERDA, we extend the existing response-time analysis for Controller Area Network (CAN) to support mixed transmission patterns which are implemented by some of its higher-level protocols that are used in the industry. In order to show the applicability of our techniques, we provide a proof of concept by extending the Rubus Component Model which is used for the development of software for vehicular embedded systems by several international companies. We also implement the ERDA along with the extended analysis for CAN in the existing industrial tool suite the Rubus-ICE. Moreover, we conduct case studies to validate our methods and techniques.
