AUTOSAR


AUTOSAR (AUTomotive Open System ARchitecture) is a worldwide development partnership of automotive interested parties founded in 2003. It pursues the objective of creating and establishing an open and standardized software architecture for automotive electronic control units (ECUs) excluding infotainment. Goals include the scalability to different vehicle and platform variants, transferability of software, the consideration of availability and safety requirements, a collaboration between various partners, sustainable utilization of natural resources, and maintainability throughout the whole "Product Life Cycle".

The AUTOSAR development partnership was formed in July 2003 by BMW, Bosch, Continental, DaimlerChrysler, Siemens VDO and Volkswagen to develop and establish an open industry standard for automotive E/E architecture. In November 2003, Ford Motor Company joined as a Core Partner, and in December Peugeot Citroën Automobiles S.A. and Toyota Motor Corporation joined. The following November General Motors also became a Core Partner. After Siemens VDO was acquired by Continental in February 2008, it ceased being a self-contained Core Partner of AUTOSAR.

Since 2003, AUTOSAR has provided four major releases of the standardized automotive software architecture and one release of Acceptance Tests. The work of AUTOSAR can be divided into three phases:

In 2013, the AUTOSAR consortium entered a continuous working mode to maintain the standard and provide selected improvements (including the release R4.2 as well as Release 1.0 of Acceptance Tests).

AUTOSAR provides a set of specifications that describes basic software modules, defines application interfaces and builds a common development methodology based on standardized exchange format. Basic software modules made available by the AUTOSAR layered software architecture can be used in vehicles of different manufacturers and electronic components of different suppliers, thereby reducing expenditures for research and development and mastering the growing complexity of automotive electronic and software architectures. Based on this guiding principle, AUTOSAR has been devised to pave the way for innovative electronic systems that further improve performance, safety and environmental friendliness and to facilitate the exchange and update of software and hardware over the service life of the vehicle. It aims to be prepared for the upcoming technologies and to improve cost-efficiency without making any compromise with respect to quality.
