VIL Testing: Importance of Precise Reference Motion and Navigation Sensing

As every driver has already experienced, ADAS functions are becoming more and more complex and numerous, and are increasingly leading to automated driving. Therefore, the classic test and measurement procedures on the proving ground with complex scenarios and hardware setups are becoming more and more complex and sometimes can only be realized under difficult environmental conditions. Vehicle-in-the-loop (VIL) is used as a much more effective alternative to classical functional testing and for the validation of measurement data. This is because the vehicle-in-the-loop method closes the gap between simulation and physical measurement by integrating a synchronized virtual environment into a real vehicle. Test scenarios and maneuvers are performed in a simplified track environment - ensuring correlation between physical and virtual vehicle positioning.

A virtual test environment offers the possibility to collect data in different scenarios under real road conditions: flexible, safe and without complex test setup. The productivity of test stations and measuring devices can thus be scaled and optimized considerably.

In order to obtain valid, reliable and highly accurate measurement results in VIL testing, high-precision navigation with a powerful inertial system is required. Discover how both solutions - IPG‘s VIL solution and GeneSys‘ GNSS-based inertial system ADMA - enable complex ADAS test scenarios, and even generate a virtual test environment in real-time at different conditions.
