Challenges in the design of automotive software

Since the foundation of AUTomotive Open System ARchitecture (AUTOSAR), the AUTOSAR Core Partners and more than 65 Premium and Development Members have been working on the standardization of vehicles´ software architecture. As a result of its joint development activities AUTOSAR has already provided several Releases, which comprise a set of specifications describing software architecture components and defining their interfaces. With Release 2.1 and Release 3.0/3.1 the majority of partners and members started their series roll-out of AUTOSAR. When introducing the AUTOSAR standard in series products dedicated migration scenarios need to be applied. BMW is migrating to AUTOSAR Basic Software in its current and upcoming product lines. This includes also common functionality that is today already realized as AUTOSAR compliant extensions to the basic software. Further on BMW´s strategy on providing application software as ready-to-integrate AUTOSAR software components is described.
