The development cycles around the vehicle are constantly shortening. Agile development helps master complexity. Changing requirements can be accommodated flexibly and in compact time units. But testing must also keep up with this speed and be fast and uncomplicated during the development process. This is a challenge for test processes and their methodology that we at IAV meet with customized solutions. In the Communication & Diagnostics Test Center, we check the transmission of data and information between ECUs and vehicle peripherals for conformity. And we do this flexibly, quickly and individually tailored to the project in question.

Experts for communication protocols

As a premium member of the AUTOSAR Consortium and partner of numerous OEMs and suppliers, we are directly involved in the development of new test methods and the evaluation of test results. With tests accompanying the development process, we can identify errors for our customers at an early stage and thus prevent delays in the project. Our test center is also the right address for release, error verification and smoke tests.
