As the last presentation showed, data transmission have to be robust. This is especially true, when it comes to autonomous driving. Dr. Christian Rusch (Manager R&D Data Connectivity) and Hajo Wetzel (Director Center of Excellence Embedded) from TE Connectivity are now talking about the changed requirements and solutions.
„We’re currently operating at the limit of physics: We have control units with more than 20 high-speed data connections, the package needs to become smaller and we have to develop and implement in a shorter time. Meanwhile the safety as well as the redundancy and fault tolerance have to increase.“
To meet those requirements, Wetzel and Dr. Rusch present a service-oriented architecture (SOA). In such an architecture, the intelligence is centralized. This requires a reliable high-speed infrastructure at the top layers. The reflex-level electronics on the other side is decentralized. Basic intelligence is achieved by digitization at sensor/actuator level, so the sensors can digitally talk to the ECU.
