New electronic architecture

The core elements and central nervous system of the new E³ 1.2 electronic architecture are five high-performance computers (HCP), which cover all vehicle functions - from the drive and assistance systems to the infotainment and comfort systems through to the safety systems and backend networking. The overriding aim in developing the E³ in version 1.2 was to create a scalable and future-proof electronic architecture that can be used throughout the Group.

The transfer of functions from the sensor-actuator level to the computer level, i.e., the increasing decoupling of hardware and software, ensures the PPE can reliably cope with the increasing complexity in the coming years. An additional focus of development was on high-performance and secure networking of domain computers, control units, sensors, and actuators in order to master more complex systems and maintain modularity.

Another important goal was the high-performance, seamless backend connection for car-to-X swarm data applications and computationally intensive offboard functions. Audi is gradually implementing the new electronic architecture in all future vehicle models.
