AUTOSAR (AUTomotive Open System ARchitecture) is an open and standardized automotive software architecture, jointly developed by automobile manufacturers, suppliers and tool developers. It is a partnership of automotive OEMs, suppliers and tool vendors whose objective is to create and establish open standards for automotive E/E (Electrics/Electronics) architectures that will provide a basic infrastructure to assist with developing vehicular software, user interfaces and management for all application domains. This includes the standardization of basic systems functions, scalability to different vehicle and platform variants, transferability throughout the network, integration from multiple suppliers, maintainability throughout the entire product life-cycle and software updates and upgrades over the vehicle's lifetime as some of the key goals. == Goals == AUTOSAR has been devised to: * Pave the way for innovative electronic systems that further improve performance, safety and environmental friendliness * Be a strong global partnership that creates one common standard: "Cooperate on standards, compete on implementation" * Be a key enabling technology to manage the growing electrics/electronics complexity. It aims to be prepared for the upcoming technologies and to improve cost-efficiency without making any compromise with respect to quality * Facilitate the exchange and update of software and hardware over the service life of the vehicle As stated in the official website, the goals of AUTOSAR are: * Implementation and standardization of basic system functions as an OEM wide "Standard Core" solution * Scalability to different vehicle and * Integration of functional modules from multiple suppliers * Consideration of availability and safety requirements * Redundancy activation * Maintainability throughout the whole "Product Life Cycle" * Increased use of "Commercial off the shelf hardware" * Software updates and upgrades over vehicle lifetime The above mentioned goals are pursued by choosing a software architecture that supports a design model based on component based design. The model is supported by an automated methodology to create the software executable for the ECUs, starting from the design model and the properties and physical topology of the hardware. This way the AUTOSAR-project tries to create a paradigm shift in automotive software development from an ECU based approach to a function based approach. VDC Research reports in 2008 that adherence to AUTOSAR is expected to double in the next two years (from 7% to 14%).〔("Automated Defect Prevention for Embedded Software Quality" ) white paper by VDC Research〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AUTOSAR」の詳細全文を読む スポンサード リンク
