AUTOSAR (Automotive Open System ARchitecture) is a global development partnership that was founded in 2003 by a consortium of leading automotive manufacturers, suppliers, and tool developers. Its aim is to establish a common standard for software architecture in the automotive industry.
The AUTOSAR standard defines a common software architecture for the entire automotive electronics system, from the application layer down to the hardware abstraction layer. It provides a standardized set of interfaces, data structures, and configuration parameters that enable the development of automotive software that is portable across different hardware platforms and electronic control units (ECUs).
AUTOSAR defines three layers of software architecture: the Application Layer, the Basic Software Layer, and the RTE (Run Time Environment) Layer. The Application Layer contains the application software, while the Basic Software Layer contains software components that provide basic functions such as memory management and communication. The RTE Layer is responsible for managing the communication between the Application Layer and the Basic Software Layer.
AUTOSAR is widely adopted in the automotive industry and is used by many major automotive manufacturers and suppliers. It helps to reduce development time and costs, and enables the reuse of software components across different ECUs and vehicle models.
