Advancing Traffic Efficiency and Safety through Software

2 Foreword Foreword How can the automotive-specific language EAST-ADL contribute in solving present challenges in the development of automotive systems? Cornerstones of high quality embedded systems are mature engineering techniques using model-based development and standardized, reliable architectures. Industrial experience shows that model-based development techniques are required in the automotive domain to improve the quality and dependability of embedded systems. EAST-ADL focuses mainly on the architecture-induced complexity of automotive embedded systems. It provides an ontology for automotive electronics and software, making system models unambi-guous, consistent and exchangeable. The primary scope of the EAST-ADL modeling concepts used to be the single vehicle and its embedded system. During ATESST2, the scope of the approach has been extended to cooperative active safety systems, thus covering also the interaction with systems in other vehicles and infrastructure. The ATESST2 project team has a strong background in the automotive domain. As a consequence, the developed language – while state of the art – can be flexibly introduced and adapted in practical applications, reflecting in particular the fragmented development process between vehicle manufacturer and automotive supplier, the highly complex variability of the systems, the different automotive-relevant standards such as AUTOSAR, SysML, AADL, Marte… and the need for highly dependable systems. The EAST-ADL has gained high visibility also in the context of the CESAR project, a flagship project of the Joint Undertaking Artemis addressing development processes for safety relevant embedded applications, comprising some 20 large enterprises in the transportation domain, and also addressing automation. In an ongoing cooperation between ATESST2 and CESAR, the first version of the CESAR reference technology platform builds on an augmentation of the EAST-ADL meta-model with the key concept of contract based design. EAST-ADL aims to set a new standard in the automotive domain. Users of AUTOSAR, the international, standardized automotive software architecture and exchange format, will be able to apply the EAST-ADL to cover complementary information and more abstract modeling levels. In short, with EAST-ADL the ATESST2 team has provided a highly relevant model-based development technique for those who are seeking to improve industrial automotive system development. The inclusion of embedded system technology in vehicles has had – and is still having – a radical impact on their development, production and maintenance. Over the past decades, automotive embedded systems have evolved from single standalone computer systems, simple enough to be designed and maintained with a minimum of engineering, to distributed systems including several networks, …
