AUTOSAR Classic Platform
The Production-Proven Standard for In-Vehicle ECUs

The AUTOSAR Idea

AUTOSAR (Automotive Open System Architecture) is a standardization initiative of leading automotive manufacturers and suppliers that was founded in 2003.

With the rising number of complex functions, the develop­ment of in-vehicle electronics is becoming increasingly broader in scope and more complicated. The idea behind AUTOSAR is to avoid continually re-developing the same or similar software components. The worldwide development partnership has set the goal of establishing an open standard for the system architecture in the automotive industry.

Reduced development effort and improved quality are important reasons for introducing a uniform and producer independent system platform. Hardware and software are decoupled from one another to assure such results. The AUTOSAR concept is based on modular components with defined interfaces.

AUTOSAR Adaptive Platform

The AUTOSAR development partnership has added a new standard to its portfolio which is based on POSIX operating systems: the AUTOSAR Adaptive Platform. The primary motivations for the new platform are autonomous driving, Vehicle-to-X (V2X) applications and the growing external networking of vehicles (Connectivity).

The previous standard will continue to be offered under the name AUTOSAR Classic Platform.

AUTOSAR Fundamentals

The Vector basic software MICROSAR contains modules of the AUTOSAR 4.3 standard and numerous enhancements.

Basic elements of the AUTOSAR architecture are, among others, formally defined software components (SWC) with clearly specified interfaces to the basic software (BSW) that in turn provide fundamental standard services, such as bus communication, memory management, IO-access, system and diagnostic services. Another basic element is the runtime environment RTE that connects the SWCs with the BSW.

The Virtual Functional Bus (VFB) specified by AUTOSAR delivers the conceptual foundation for the communication of SWCs with each other and the use of BSW services. The development of the SWCs is based on the VFB. In this manner, the SWCs are independent of the ECU hardware. This makes them easier to reuse and integrate into different projects on different platforms. The VFB is implemented in a specific vehicle by using a specifically configured RTE together with a suitably configured BSW for each ECU.

AUTOSAR Workflow

During system design, the architecture of the functional software is determined. This is done by defining SWCs and their distribution over the ECUs. Network communication is also determined in this step. The result is the system description – an AUTOSAR XML file from which one generates a specific ECU extract of system description for every ECU.

During ECU development, the SWCs are designed and implemented and the BSW and RTE are configured. The developer determines the necessary amount of basic software for his project by configuration. In this manner, he can optimize the entire ECU software. The result of the configuration is an ECU Configuration Description (AUTOSAR XML file) that is tuned to the ECU Extract of System Description.

Based on the ECU Configuration Description, code generators generate and/or adapt the BSW for the ECU software. The RTE is also created in an ECU-specific manner.

This method defined in AUTOSAR significantly simplifies the integration of application software into an ECU. Manual software adjustment becomes unnecessary.

The challenge:

  • E/E complexity is growing fast
  • Quantity of software is exploding
  • Many different hardware platforms are used
  • Development processes and data formats are not harmonized

The main objectives of AUTOSAR:

  • Improve software quality and reduce costs by re-use
  • Re-use of functions across carlines and across OEM boundaries
  • Re-use of development methods and tools
  • Re-use of basic software
