Functional Architecture

Our experts are in full command of the growing complexity in vehicles and develop optimized solutions for electrical and electronic systems

Today, vehicle functions are distributed to a high degree over many control units. Our experts make sure all systems interact correctly. We can provide you with support from the concept phase to validating production components.


This is about how to distribute algorithms among the control units. Does a centralized computer make sense or would several distributed processors be better? How can new algorithms be distributed over existing hardware in a derivative? What effects does a proposed architecture have on development input, costs and weight? We answer these questions as early as the concept phase. In production development, we systematically document the interconnected systems to provide an overall picture of E/E system interaction.

Distributed Systems

During the development process we make sure from the outset that the distributed systems interact in the way we want them to. To do this, we draw up specifications, develop technical solutions, produce prototypes and oversee collaboration in development as well as in the integration and testing process.

Interfaces to Trailer and Superstructures

There are many different ways of transferring signals between the truck and its superstructures, work attachments, semitrailers or trailers – like the CAN bus for serial data transfer, image transmission systems for cameras or WiFi for wireless links. IAV’s engineers can develop the right solutions for you and help you integrate them.

Integration and Testing

We test the algorithms on hardware-in-the-loop test benches, in reference vehicles and on vehicle prototypes, either at IAV or on location at our clients. We take advantage of systems developed in-house for generating test cases to guarantee reliable validation. In all of our activities, we benefit from our internal IAV network – this provides a pool of specialists in all disciplines who are consulted to resolve highly specific matters of detail.
