Automotive Open System Architecture (AUTOSAR) is an open and standardized software architecture, jointly developed by automobile manufacturers, suppliers and tool developers. Its objective is to create and establish open standards for automotive basic infrastructure to assist with developing automotive software, user interfaces and management for application software. The AUTOSAR initiative has developed a layered software development approach that allows companies to cooperate on standards and to compete on implementations, enabling developers to create high quality, reusable software components that help drive down costs, while speeding up time to market.
