In terms of hardware, two high-performance computers known as ICAS (In-Car Application Servers) are the main components in the electronic architecture of the ID.3. They bring together a number of tasks that are otherwise spread over a number of small computers – however, basic vehicle functions such as drive system and brake control remain on their separate control units.
Like on a stationary server, the software architecture is designed to be a broad service platform. This simplifies the exchange of data and functions between the systems without any compromises in terms of security. The new electronic architecture lets the vehicle remain up to date at all times and even be improved in some areas – with over-the-air updates using the mobile signal network. Volkswagen is thus taking the next important step in its transformation into a software-oriented mobility provider.
