Vehicle development in virtual environments

IAV simulates products that do not yet exist as software models. Because unlike in the past, vehicles and other products can now be developed, optimized and tested completely virtually. They no longer need to be tested in a laboratory or a specific environment. In 2018, IAV developed a concept that combines a real test vehicle with a virtual environment and enables reproducible, hazard-free testing that saves resources.

The idea arose from practical experience, because at that time modern driver assistance systems were being used in more and more driving situations.

“The test engineers in the vehicle see the real test environment in the visualization as well as the virtually generated objects moving on the real test track, and experience the real reaction of the test vehicle.”
Dr. Roland Kallweit, Head of Department Predictive Safety at IAV

Vehicle behavior in simulation tools

With virtual vehicle simulations, automotive engineers can quickly see how a car would behave in reality. And they run virtual tests in different scenarios to test the functions of embedded software.

Digital simulations make it possible to test functions using virtual prototypes instead of real ones. For example, driving behavior, values in the wind tunnel or properties of individual components can be digitally calculated and optimized.

To simulate critical situations, IAV uses digital prototypes to gradually move from a virtual to a real product.

The videos show scenarios from everyday testing.

Scene 1: A person crosses the street in front of an automated vehicle.While only parts of the software can be tested in the 2D simulation, such as path planning, perception can also be examined in 3D. On a test track, hardware and real vehicle dynamics come into play.In field tests, the automated vehicle has to deal with all the challenges of reality.
