AUTOSAR Timing Models Minimize ECU Risks
Publication: EE Times Automotive Designline
February 27, 2012 -- AUTOSAR has been introduced as an automotive standard for electronic control unit (ECU) software development and is now used in series projects either in version 3.2 or 4.0 (including Timing Extensions), depending on the OEM. From the software development perspective, AUTOSAR is already increasing productivity tremendously through standardization.
However, from the system development perspective, key questions remain:
The goal is to have a system integration available at the end of the development which fulfils the above mentioned requirements, which uses the ECU resources in the best way, and which can accommodate extensions. The steps to this system integration include the mapping of functional architectures to software architectures, the creation of the run-time environment (RTE) and OS configuration (schedule), and the integration of basic software (BSW) elements.
