The approach of the 15 months old start-up APTIV is a further development based on the satellite architecture. In their approach sensors are still satellites but in between they use PowerData Centers who function as a docking station for sensors and are then connected to Central Compute Clusters which operates as an open server platform with standardized interfaces. Power is controlled by a unified Power / Data backbone which is a modular solution for common vehicle power supply and data delivery.

Our next speaker Magnus Svensson (Advanced E/E Architecture Manager EMEA) from the Irish supplier and start-up APTIV will answer how the future challenges lead to a different way on how to develop EE architectures.

Svensson starts with a comparison between the classic and the satellite architecture: The classic architecture has an ECU for each feature which offers great scalability but requires too much wires and and makes it almost impossible to improve/update features in the future.
In comparison the the sensors in a satellite architecture function as satellites and only provide raw data to the central compute units. This reduces complexity, wires and allows for functional updates over time.

Dr. König gives an example how important this conference here in Ludwigsburg is: Last year during the conference, a group of OEMs (including Daimler with Dr. König) and suppliers met, shared contacts and has since been working on the establishment of new guidelines for thermal simulations which are released this year.
