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.
Indoor Tests with reproducible weather conditions
- Weather conditions like fog and different lighting
- Area of 1,600 m2 (84 m x 19 m)
- Rain system for precipitation intensities between 5 mm/h and 98 mm/h, as well as corresponding drop size distribution
- Fog system
- Hall basic lighting, which can visualize indirect natural light of at least 2000 Lux (10 cm above the road) and has 90 kW installed light output
- Secondary systems such as aeration/ventilation, heating, filter system, water recycling, water filters, etc.
- Asphalt road with customizable road layout and road limits
