With the upcoming extensions, the Autosar consortium reacts to the demand from automotive OEMs, said Schmerler whose primary job is general manager for electronics, electrics and architecture at carmaker Daimler. The upcoming Autosar version will also include more support for functional safety processes - a matter that currently is on the mind of the industry.
Responding to critics from the automotive industry watchers that not all OEMs are interpreting the Autosar standard in the same way, Schmerler defended the industry. "Yes there are different releases in place at the OEMs. But since the start of the respective vehicle developments has started at different points in time, it is only logic that these developments are based on the release status that was current when they launched their developments. And once they have committed to a certain release, they will stay with it throughout the design cycle", Schmerler said. And, yes, Autosar is a moving target, he added - "but this is the way all standards are developed".
In order to avoid problems arising from changing release versions, newer versions are always backwards compatible with older ones. "Nevertheless, it would be impossible to completely rule out incompatibilities," he said. "Otherwise we would obstruct the possibilities for technological progress".
With regard to the two major releases currently circulating in the industry, Schmerler said that release 3 and release 4 will be available for a long time. Users should expect minor bug fixes, but the long-term stability of these versions is a common goal.
Electric driving does not generate additional requirements for the software standard, Schmerler said. "Yes, we have identified electromobility as a future application, but ECUs for electric vehicles are not different in terms of software requirements", he said, adding that today "all OEMs are working on the development of electric vehicles".
