Project develops interaction of software components for future cars
In the SofDCar joint project, a number of research institutes and automotive suppliers under the leadership of Bosch plan to develop new methods and processes for the data architecture and usage models of future vehicle generations. The challenge: in future, software updates must be possible over the entire service life of the cars - even if the model is no longer being built.

Experts from industry and science work together to create standardised rules and processes so that the electronic interaction in the car works - similar to a large orchestra. After all, concerted interaction between everyone is the prerequisite for new functions in and around the vehicle to be developed more quickly in future and to reach drivers safely. A total of 13 companies and research institutions have been working on this since August in the "Software-Defined Car" project (SofDCar for short).

"With a new view of software and data, we are laying the foundations for much more flexibility in dealing with new functions and data relating to modern vehicles," says Dr Andreas Westendorf, who heads the project at consortium leader Bosch.

An important project goal is to overcome the complexity of today's E/E architectures. In some cases, more than 100 control units are installed in current vehicles. The high complexity of electrical and electronic systems and their architecture will continue to increase in the future, but at the same time must remain manageable. Only in this way will it be possible in the future to ensure that vehicle functions can be updated at any time and thus remain safe throughout the entire life cycle of a car - after all, up to 20 years. A set of rules for the smooth cooperation of the various electronic components and systems in the car is therefore needed more than ever.

The aim of the "SofDCar" project is to ensure that in future all software updates and upgrades follow rules and processes by which they can be controlled and are subject to the application of a consistent methodology for functional and IT security. This ensures that individual programmes do not interfere with each other and work without errors in the system. "The "SofDCar" project has taken on the task of mapping the IT jungle in
