- Embedded software systems in vehicles are of rapidly increasing commercial importance for the automotive industry. Current systems employ a static run-time environment; due to the difficulty and cost involved in the development of dynamic systems in a high-integrity embedded control context. A dynamic system, referring to the system configuration, would greatly increase the flexibility of the offered functionality and enable customised software configuration for individual vehicles, adding customer value through plug-and-play capability, and increased quality due to its inherent ability to adjust to changes in hardware and software. We envisage an automotive system containing a variety of components, from a multitude of organizations, not necessarily known at development time. The system dynamically adapts its configuration to suit the run-time system constraints.This paper presents our vision for future automotive control systems that will be regarded in an EU research project, referred to as DySCAS (Dynamically Self-Configuring Automotive Systems). We propose a self-configuring vehicular control system architecture, with capabilities that include automatic discovery and inclusion of new devices, self-optimisation to best-use the processing, storage and communication resources available, self-diagnostics and ultimately self-healing. Such an architecture has benefits extending to reduced development and maintenance costs, improved passenger safety and comfort, and flexible owner customisation.Specifically, this paper addresses the following issues: The state of the art of embedded software systems in vehicles, emphasising the current limitations arising from fixed run-time configurations; and the benefits and challenges of dynamic configuration, giving rise to opportunities for self-healing, self-optimisation, and the automatic inclusion of users’ Consumer Electronic (CE) devices. Our proposal for a dynamically reconfigurable automotive software system platform is outlined and a typical use-case is presented as an example to exemplify the benefits of the envisioned dynamic capabilities.

- This paper proposes a vehicular control system architecture that supports self-configuration. The architecture is based on dynamic mapping of processes and services to resources to meet the challenges of future demanding use-scenarios in which systems must be flexible to exhibit context-aware behaviour and to permit customization. The architecture comprises a number of low-level services that will provide the required system functionalities, which include automatic discovery and incorporation of new devices, self-optimisation to best-use the processing, storage and communication resources available, and self-diagnostics. The benefits and challenges of dynamic configuration and the automatic inclusion of users' Consumer Electronic (CE) devices are briefly discussed and the self-management and control-theoretic technologies that will be used are described in outline. A number of generic use-cases have been identified, each with several specific use-case scenarios. To demonstrate the extent of the flexible reconfiguration facilitated by the architecture, some of these use-cases are described, each exemplifying a different aspect of dynamic reconfiguration.

DySCAS System Architecture
- 2007
-
Rapport (refereegranskat)abstract
- This deliverable provides an architectural strategy and overall system design forthe DySCAS middleware system as a first step towards a complete systemspecification. The DySCAS Basic Architecture captures both the systemconceptualization and an initial function-level outline without consideringimplementation and technology details. It defines the middleware system in termsof its application and operational contexts, expected features, middleware servicesthat group functions, behaviours, as well as the structuring and implementationdecisions that are most crucial to satisfy the given set of requirements. In thisdocument, we also outline some fundamental strategies for binding themiddleware components to the target platforms and infrastructures and forhandling potential errors at both initialization-time and rum-time, while taking thetechnology support and domain needs into consideration.This deliverable also covers the rationale behind the architecture solutions andprovides a generic framework that relates architecture principles and styles, wellknownmechanisms, and reference models to the expected functionalities andqualities of DySCAS. The aim is to consolidate the proposed solutions and also tofacilitate the communications between DySCAS partners and to third-parties.

The benefits and challenges of dynamic configuration and the automatic inclusion of users' Consumer Electronic (CE) devices are briefly discussed. The dynamic configuration and control-theoretic technologies used are described in outline and the way in which the demands of highly flexible dynamic configuration and highly robust operation are simultaneously met without compromise, is explained. A number of generic use-cases have been identified, each with several specific use-case scenarios. One generic use-case is described to provide an insight into the extent of the flexible reconfiguration facilitated by the architecture.
