The sensors of automated driving functions and advanced driver assistance systems must function safely under all conditions. But the influence of the ever-changing weather is often neglected. NCAP certification tests such as the autonomous emergency braking for vulnerable road users (AEB VRU) are only carried out in good weather, not under rainy or foggy conditions. The reason lies in the lack of reproducibility during real-world tests outdoors.


We provide the solution to this challenge with our center of excellence, which enables the physical simulation of environmental impacts such as rain, fog, and various lighting conditions.
Representing these conditions realistically comes with numerous requirements: from the exact simulation of raindrops to water recycling in the rain system and simulating twilight.
Our indoor sensor testing ground meets all these requirements: For your ADAS/AD sensors we provide a unique testing and validation environment that covers various critical weather situations. Based on reproducible indoor measurements, you get models for the virtual simulation of different weather conditions and the relevant sensors.
We make sure that your intelligent sensors work precisely for a safe future.
Precision Throughout
Customers who do not have their own specific test facility can obtain professional support: In Roding we perform relevant tests in real-world conditions, precisely and in a way that can be reproduced. We compare the findings obtained in the lab with real data collected from the road.
State-of-the Art Equipment
The perfect technical equipment also enables us to visualize country-specific requirements at our indoor facility, safeguard corresponding functions, and thus support derivative development.
