Guest editorial on special section: Automotive Software Architecture

h 0 A modern day vehicle might be seen as a complex system conainingmillions of lines of code running onmultiple microcontrollers reating a heterogeneous, deeply coupled networking system. Nowaays trends like V2X (Vehicle to Vehicle, Vehicle to Infrastructure, Veicle to Pedestrian), electric vehicles or self-driving cars are all based n software and electronics. These new features require new engieering approaches and more advanced software architectures suitble for the automotive domain. The alignment of the architectural, esign, and engineering concepts are in urgent need given the ever ncreasing software complexity and size. Furthermore, up to 90% of he innovation in modern cars are enabled by software, thus, more nd more innovations (e.g. augmented reality, connectivity, and Inernet of Things) need more sophisticated and reliable approaches rom the software architecture and component-based software engieering community. Therefore, to bring together researchers and practitioners in the rea of automotive software engineering, the internationalWorkshop n Automotive Software Architectures (WASA) was held on May 4, 015 in Montréal, Canada and co-located with the 12th Working EEE/IFIP Conference on Software Architecture (WICSA) and the 9th ompArch federated conference series, the premier gatherings of oftware architecture and component-based software engineering ractitioners and researchers. The objective of the workshop is to ecome the premier forum for presentation of research results, ndustrial experience reports, and future trend discussions on the utomotive software architecture field. WASA gives researchers and practitioners a unique opportunity o share their perspectives with others interested in the various asects of the automotive software architecture field.
