Modularity and configurability

• Definition of a modular software architecture for automotive electronic control units
• Consideration of HW dependent and HW independent SW modules
• Integration of SW modules provided by different suppliers to increase the functional reuse
• Transferability of functional SW-modules within a particular E/E-system at least at the final software linking process
• Resource optimized configuration of the SW infrastructure of each ECU depending on the function deployment
• Scalability of the E/E-system across the entire range of vehicle product lines

Standardized interfaces

• Standardization of different APIs to separate the AUTOSAR SW layers
• Facilitate encapsulation of functional SW-components
• Definition of the data types of SW-components
• Standardization of interfaces of basic SW modules of the SW infrastructure

Runtime Environment (RTE)

• Provision of inter- and intra-ECU communication across all nodes of a vehicle network
• Located between the functional SW-components and the basic SW-modules
• All entities connected to the AUTOSAR RTE must comply with the AUTOSAR specification
• Enables the easy integration of customer specific functional SW-modules
