AUTOSAR (AUTomotive Open System ARchitecture) is a global partnership of leading companies in the automotive and software industry to develop and establish the standardized software framework and open E/E system architecture for intelligent mobility. Basically, it provides specification using which you can develop a software architecture for automotive applications.
Core Partners of AUTOSAR
Nine companies founded the AUTOSAR partnership to consolidate the expertise of partner companies in the automotive industries and define an automotive open system architecture standard to support the needs of future automotive applications.
BMW group, Bosch, Continental, Daimler AG, Ford, General Motors, PSA group, Toyota, Volkswagen group are 9 core partners
hese organizations came together to define a standardized automotive software architecture that enables:
- Reusability of software components
- Scalability across vehicle platforms
- Interoperability between suppliers and OEMs
- Easier integration and certification of complex software systems
The quote from Günter Reichart, AUTOSAR Spokesperson, emphasizes the importance of collaboration:
“If a company does it alone it is one proprietary solution. If it is shared and used by several partners it becomes technology, and with broad application it becomes state of the art and alleviates certification.”
This reflects AUTOSAR’s goal of creating a non-proprietary, widely adopted platform that benefits the entire automotive ecosystem.
AUTOSAR Standards
The primary goal of the AUTOSAR development partership is the standardization of basic system functions and functional interfaces
- Classic AUTOSAR
The AUTOSAR Classic Platform is a software platform based on a layered architecture with standardized interfaces between software modules. It focuses on deeply embedded ECUs with real-time and safety-critical requirements. Best suited for traditional automotive systems such as powertrain, body electronics, and chassis systems. The main concept behind classic platform is separation of hardware independent application software and the hardware-oriented base software by means of a software abstraction layer called RTE(Run Time Environment)
2. Adaptive AUTOSAR
The AUTOSAR Adaptive Platform implements the AUTOSAR Runtime for Adaptive Applications (ARA) and consists of functional clusters grouped into Services and the AUTOSAR Adaptive Basis. It provides two types of interfaces, Services and APIs, and is the AUTOSAR solution for high-performance ECUs to build safety-related systems. The platform is designed to meet the requirements of highly automated vehicles and supports dynamic updates and reconfigurations of software systems.
Both platforms aim to improve software quality, development efficiency, and long-term maintainability. By adhering to AUTOSAR standards, automotive companies can future-proof their software architecture, support over-the-air updates, and reduce integration effort across global supply chains.
