Why was this location chosen?
It is situated near Stuttgart, close to a number of German automotive OEMs and Tier1 suppliers, making it highly relevant for correlation with real world tests.
What are the key features or challenges of this location?
It includes sections of Autobahn with three or more lanes, long tunnels, autobahn-to-autobahn junctions, rest stop locations and junctions with standard rural and town roads. It also combines north-south and east-west road orientation. All of these aspects are contained within a compact area, avoiding the need for an excessively large model.
What are the special technical features of the model?
This was the first rFpro bi-directional driving loop on a full width autobahn. This entailed reproducing a much wider drivable road surface than we had ever built before on a public road model.
What are the benefits for customers using this model?
The real world location is replicated with all its naturally occurring variations, rather than the repeated patterns which are computer generated. This leads to far higher correlation with real world perception tests. Also, potentially dangerous high speed autobahn manoeuvres can be tested without any risk to humans or test equipment. These include cutting into busy traffic, lane departures and negotiating slip road entries and exits at high speed.
What types of vehicle components and sensors have been developed using this model?
Customers have developed ADAS and ADS cameras and control systems with this model. It is fully capable of handling general high-speed vehicle dynamics testing, such as lane change manoeuvres, with LiDAR-accurate road surface inputs which are more realistic than perfectly flat proving grounds.
