E³ 1.2 as the foundation for a new level of digitalization

The core elements and central nervous system of the new E³ 1.2 electronics architecture are five high-performance computers (HCPs) that manage all vehicle functions – from the drive system and assistance systems and the infotainment and comfort systems to the safety systems and backend connectivity. The overarching goal when developing the E³ 1.2 was to create a scalable and future-proof electronic architecture that can be used throughout the VW Group. The transfer of functions from the sensor-actuator level to the computer level, i.e., the increasing decoupling of hardware and software, will be able to manage the increasing complexity in the years ahead reliably. Another development focus was high-performance and secure networking of domain computers, control units, sensors, and actuators to master more complex systems and support modularity. Another important objective was the high-performance, seamless backend connection for car-to-x swarm data applications and CPU-intensive off-board functions. Audi will introduce the new electronics architecture to all future vehicle models one by one.
