The partnership will involve third parties in the development of AUTOSAR through the following types of partnership:

Premium Partners   Development Partners   Associate Partners   Attendees

If you want to exploit commercially AUTOSAR technology in automotive or derived applications, you have to sign an AUTOSAR Partner's Agreement. After signing, you have the right to use the AUTOSAR technology royalty-free. Associate Partners get early information and access to released AUTOSAR specifications. In addition, Premium and Development Partners contribute to working groups and get access to current information and specifications under development for upcoming releases.

There are several forms of partnerships. In order to become a contributing partner (Premium Partner, Development Partner) you have to fill in a registration form and provide a positioning paper. The process to become an Associate Partner or Attendee is even simpler. See "How to Join?" for details.

You can use the AUTOSAR standard for automotive and derived applications. Automotive application means applications related to engine powered, land-based, non-railed vehicles, such vehicles intended for primary transportation purposes.

Moreover since 2011, AUTOSAR has broadened its field of use to non-automotive derived applications such as marine, railway powertrain, agriculture and forest machinery, construction and mining machineries, compressors and pumps, power generators, and so on. However, any use for ultra-hazardous use-cases is explicitly excluded, such as aerospace and aviation, nuclear power, chemical and/or biological reactors, petrochemical, military (except for military marine transportation vessels).

The first cars with AUTOSAR technology inside were launched in the market in 2008. Today, the standard is very well accepted and AUTOSAR products are successfully applied in many vehicle projects. The majority of the world’s car manufacturers is AUTOSAR partner, and most of them already have AUTOSAR technology in use or concrete exploitation plans. The car production of AUTOSAR OEM partners covers about 80% of the global production.

The standardization will result in a higher degree of re-use of components. That means development costs can be put on a wider basis. Another cost reducing factor results from the exchangeability between supplier's solutions. This surely leads to more competition.

AUTOSAR is focusing on technology and does not plan or propose any kind of business models. This question will find various answers in the market.

The interoperability of solutions requires a high quality standard. AUTOSAR has defined a process to ensure such high quality when changes are introduced in a revision or when new features are introduced in new minor or major releases.

AUTOSAR is also continuously monitoring the interoperability of AUTOSAR tool chain solutions and provide acceptance tests for the Classic Platform which enable an early assessment of suppliers’ basic software solutions in a development process.

AUTOSAR’s Adaptive Platform is designed for interoperability with other software platforms. By using dynamic service oriented communication patterns, applications can easily exchange information with for example infotainment systems.

New use-cases require the development of the Adaptive Platform.
Highly automated driving where the driver temporarily and/or partially passes responsibility for driving to the vehicle. This requires for instance communication with traffic lights, the use of high-performance micro-controllers and computing.

Car-2-X applications require interaction to vehicles and off-board systems. That means the system has to provide secure on-board communication, support of cross domain computing platforms, smartphone integration, integration of non-AUTOSAR systems, and so on.

Cloud based services will require dedicated means for security such as secure cloud interaction and emergency vehicle preemption. They will enable remote and distributed services, for instance remote diagnostics, in-field flashing, repair and exchange handling.

The Classic Platform is the first choice for deeply embedded ECUs with high demands regarding safety and deterministic execution. It targets small and medium sized microcontrollers.

The Adaptive Platform supports adaptive deployment of applications and interaction with Classic Platform and non-AUTOSAR systems. It targets high performance microcontrollers.

Updates and improvements of the standard will be introduced by future versions of AUTOSAR. Corrections are handled by a change management process and are provided as revisions of the existing releases. New features are matured in concepts which are introduced only in new releases. New minor releases accept only backward compatible features whereas major releases could introduce non backward compatible features. The AUTOSAR versions are numbered according to this scheme: <major release>.<minor release>.<revision>.

AUTOSAR’s standard Adaptive Platform makes use of agile development methods. That means functions and updates are developed in sprints. There is a regular release cycle to introduce those functions and updates into the market.

Yes, AUTOSAR provides application interfaces for Body, Chassis, Pedestrian and Occupant Safety, and Powertrain applications.

One of the main requirements of AUTOSAR is to assure the interoperability with legacy software. This will enable the re-use of existing, non-AUTOSAR compliant software, e.g. drivers. The most obvious way to reach this integration is using a Complex Driver as a wrapper around the non-AUTOSAR compliant software.

The acceptance of AUTOSAR will depend heavily on processing and memory requirements. The modular architecture of AUTOSAR provides a scalable solution where users or implementers can discard modules or configure out features of the basic software in order to limit the memory and performance impacts in micro controllers.

Using and implementing existing standards is given the highest priority.

This has been the case since the beginning of the project. For example AUTOSAR’s operating system and communication stack were based on OSEK, and the AUTOSAR System Template was based on ASAM. Furthermore AUTOSAR introduces support for new standard when there is a market need for the automotive industry.

As AUTOSAR members also participate to the elaboration of other standard, it has been possible to provide, with AUTOSAR, and standardized software solution to implement other standard as soon as they are published. For instance functional safety mechanisms were added to support ISO 26262, and the partial networking or Can FD concepts were introduced to support new versions of ISO 11898.

The primary goal of the AUTOSAR development cooperation is the standardization of basic system functions and functional interfaces. This enables development partners to integrate, exchange, and transfer functions within a car network and to substantially improve software updates and upgrades over the vehicle lifetime. Having this goal in mind, AUTOSAR pushes the paradigm shift from an ECU-based to a function-based system design attempt in automotive software development and enables the management of the growing E/E complexity with respect to technology and economics.

AUTOSAR (AUTomotive Open System ARchitecture) is a worldwide development cooperation of car manufacturers, suppliers and other companies from the electronics, semiconductor and software industry. Since 2003 they have been working on the development and introduction of an open, standardized software architecture for the automotive industry.

Today's hardware and component-driven development process is more and more replaced by a requirement and function-driven process. Engineering does not only aim at optimizing single components but optimizing on system level. This requires an open architecture as well as scalable and exchangeable software modules. Since these issues can hardly be handled by individual companies and constitute an industry-wide challenge, leading OEMs, suppliers and tool vendors jointly work on an open standard for automotive E/E architecture, within the AUTOSAR development cooperation. Basic idea is the re-use of software components so that the rising complexity can also be handled in the future.

The AUTOSAR scope includes all vehicle domains. AUTOSAR focuses on body, power train and chassis domains first. All vehicle control applications are addressed, particularly with respect to distributed functions (e.g. via busses).

The AUTOSAR development cooperation is an alliance of OEM manufacturers, Tier 1 automotive suppliers, automotive electronics, semiconductor and software companies working together to develop and establish an open industry standard for automotive E/E architecture. This standard serves as a basic infrastructure for the management of functions within both, applications and standard software modules. The AUTOSAR development cooperation is managed by its Core Partners who built up a distributed, virtual organization with decision processes based on unanimity. The actively contributing resources are provided by the globally distributed AUTOSAR Core, Premium and Development Partners. This places high demands on effective and efficient project and resource management, accurate reporting, quality assurance and transparent communication. Automotive OEMs and suppliers which are interested in AUTOSAR can apply for a Premium or Associate Partnership. The Development Partnership is especially suitable for small companies contributing on specific fields to the technological development of AUTOSAR specifications and software implementation. For details on partnership levels, please have a look at “How to join”.

AUTOSAR is the basis for additional new functions and increases the speed of their introduction. AUTOSAR enables the development of systems with increased complexity at reasonable costs with high quality, e.g. new driver assistance systems and safety systems.

The standardization will result in a higher degree of re-use of components. This will basically increase the maturity and thus also the quality of these components. Furthermore, AUTOSAR will ease both, the ECU and the system integration, which means typical pitfalls during integration are avoided.

The AUTOSAR development cooperation standardizes software technologies for automotive use. Consequently it aims to comply with all relevant standards and is therefore in regular contact with other standardization bodies, like ISO, ASAM or GENIVI. If there are existing solutions available, they are integrated, referenced or adopted when this is adequate. In case of overlaps AUTOSAR cares about compatibility issues and clarification of responsibilities.
