AUTOSAR

AUTOSAR Vision

AUTOSAR aims to improve the complexity management of integrated E/E architectures through increased reuse and exchangeability of software modules between OEMs and suppliers.

Modularity

Modularity of automotive software elements enables tailoring of software according to the individual requirements of electronic control units and their tasks.

Scalability

Scalability of functions ensures the adaptability of common software modules to different vehicle platforms to prohibit proliferation of software with similar functionality.

Transferability

Transferability of functions optimizes the use of resources available throughout a vehicle´s electronic architecture.

Re-usability

Re-usability of functions helps to improve product quality and reliability and to reinforce corporate brand image across product lines.

AUTOSAR Vision

AUTOSAR aims to standardize the software architecture of ECUs. AUTOSAR paves the way for innovative electronic systems that further improve performance, safety and environmental friendliness.

• Hardware and software will be widely independent of each other
• Development can be de-coupled by horizontal layers. This reduces development time and costs
• The reuse of software increases at OEM as well as at suppliers. This enhances quality and efficiency

 

• Architecture: Software architecture including a complete basic software stack for ECUs — the so called AUTOSAR Basic Software — as an integration platform for hardware independent software applications.
• Methodology: Defines exchange formats and description templates to enable a seamless configuration process of the basic software stack and the integration of application software in ECUs. It includes even the methodology how to use this framework.
• Application Interfaces: Specification of interfaces of typical automotive applications from all domains in terms of syntax and semantics, which should serve as a standard for application software.

AUTOSAR — Concept and Functional Domain

The AUTOSAR project objectives will be met by specifying and standardizing the central architectural elements across functional domains, allowing industry competition to focus on implementation.
