Engineering Support for Automotive Embedded Systems beyond Autosar

An account is given of EAST-ADL2, an architecture description language which is based on the Autosar concept but extends it towards a system engineering approach for automotive embedded software. The language provides concepts to describe the electronic/electric architecture of the complete system i.e. the embedded functionality and its environment at different stages of development and with different levels of detail. The features of EAST-ADL2 which add to the performance of Autosar are listed and the four architecture abstraction levels which make up the model - the vehicle level, analysis level design level and implementation level - are considered in more detail. The needs of product line engineering, requirements and verification and validation engineering, control engineering and software and real-time computer systems engineering are addressed by EAST-ADL2. By separating the description language concepts from the architecture abstraction levels, EAST-ADL2 avoids the risk of mixing information belonging to different abstraction levels and enables a structured development approach.
