AVL Focus - Issue 2025

Modern vehicles require new E/E

architectures that are secure, scalable, and

software capable. AVL provides a concrete

example of an SDV-ready concept – from

centralized computing power to seamless

OTA integration.

AVL’s Approach to

SDV E/E Architectures

Redefining the Vehicle Backbone:

he transformation toward software-defined vehicles

(SDVs) is reshaping the automotive industry. Functions

are increasingly defined by software, continuously

expanded, and updated throughout the vehicle lifecycle. This

puts growing demands on electrical/electronic (E/E) archi-

tectures: they must be secure, scalable, and flexible – serving

as the foundation for new services, enhanced comfort, and

automated driving.

The Need for New Architectures

Traditional distributed or domain-based approaches are reach-

ing their limits. OEMs face rising software complexity, shorter

development cycles, and greater integration efforts. At the

same time, expectations around connectivity, safety, security,

and software maturity continue to grow. An SDV-capable E/E

architecture must meet these challenges while operating

quietly and reliably in the background.

The AVL Architecture Example

AVL has developed a practical concept that has been intro-

duced to various commercial vehicle customers in a segment

where reliability, scalability, and total cost of ownership are

critical. Therefore, the E/E architecture concept combines

centralized and zonal approaches (see figure):

• A central vehicle domain ECU consolidates core functions

with a high degree of centralization.

• Zonal ECUs manage local I/Os and power distribution,

reducing wiring harness complexity.

• High-performance domain servers cover innovation-driven

areas such as in-vehicle infotainment (IVI) and ADAS.

• A 5G telematics unit enables fast over-the-air (OTA) up-

dates and secure cloud connectivity.

This architecture creates a scalable backbone that balances

centralized computing with modular expandability.

Value Through a Comprehensive Portfolio

AVL delivers more than architecture concepts. Its enhanced

E/E and software portfolio provides end-to-end solutions

– covering architecture definition, hardware and software

development, integration, testing, and validation. This also in-

cludes cross-domain expertise in areas such as cyber security,

functional safety, diagnostics, OTA update strategies, and data

analytics. In this way, AVL supports customers across every

stage of the V-model – from early concept through to SOP.

Experience and Agility as Key Enablers

What sets AVL apart is the combination of deep automotive

application know-how, a globally connected engineering

network, and cutting-edge methods such as single-source-of-

truth architecture definition, model-based simulation, auto-

mation, and virtual development. Equally important is agility:

in today’s fast-changing environment, agile processes are

what enable OEMs to keep pace and translate innovation into

market-ready solutions. 

“AVL’s strength is integrating

E/E and software architectures

seamlessly – backed by testing,

simulation, and global expertise.”
