The current automotive electric/electronic (E/E) architecture landscape is characterized by proprietary solutions, which seldom allow the exchange of applications between both automotive OEMs and their suppliers. It is apparent that on the basis of a continued exponential growth in functional scope, further proliferation of proprietary solutions will consume more and more resources and may become difficult to control. AUTOSAR is a joint initiative of several major industry players and aims to prepare for the increase in functional scope. This paper presents an overview over the development partnership as well as the technical concept and methodology. It concludes that introduction of an industry-wide standard of automotive E/E architecture is indeed vitally important and it is that, which will allow the industry players to concentrate on innovation rather than wasting effort when adapting existing components to different environments.

Reductions of hardware costs as well as implementations of new innovative functions are the main drivers of today's automotive electronics. Indeed more and more resources are spent on adapting existing solutions to different environments. At the same time, due to the increasing number of networked components, a level of complexity has been reached which is difficult to handle using traditional development processes. The automotive industry addresses this problem through a paradigm shift from a hardware-, component-driven to a requirement- and function-driven development process, and a stringent standardization of infrastructure elements. One central standardization initiative is the AUTomotive Open System ARchitecture (AUTOSAR). AUTOSAR was founded in 2003 by major OEMs and Tier1 suppliers and now includes a large number of automotive, electronics, semiconductor, hard- and software companies.
