With the advent of software and electronics, automotive companies are enabling innovation to improve safety, security, driver experience, and driving automation. Moreover, the complexity and size of software keep growing because of future innovations, such as adaptive cruise control, lane keeping, self-learning algorithms, etc, which all leads to the ultimate goal of autonomous driving. Consequently, increasing use of software over the years, introduced the paradigm shift by requiring automotive companies to develop their systems using architecture and model-based techniques. Although model-based techniques using e.g. MATLAB/Simulink and Stateflow are being accepted in the automotive industry as standard languages and tooling for developing automotive control software, the techniques for system and software architecture are still far from being widely accepted. This is excluding the AUTOSAR standard, which defines the language for designing and configuring automotive software architectures and identifies major architectural components of automotive systems.The goal of this workshop is to address issues related to the appropriate automotive system/software architecture and engineering techniques, which can be accepted by the automotive industry. Therefore, to bring together researchers and practitioners in the area of automotive system/software architecture and engineering, the international Workshop on Automotive Software Architectures (WASA) is being organized with the International Conference on Software Architecture (ICSA), the premier gathering of software architecture and component-based software engineering practitioners and researchers.
