Partnership Enhances Autonomous Vehicle Testing with EOL and PTI Collaboration

Ensuring the continued functionality of advanced driver assistance systems (ADAS) and autonomous driving (AD) features is crucial for the long-term safety and performance of vehicles. Manufacturers of vehicles equipped with these features must obtain certification, either from a third party, authority, or through self-certification. A vehicle-in-the-loop (VIL) test is essential to validate the correct operation of all ADAS/AD functions in the end-of-line (EOL) phase and ensure conformity of production (COP) before a vehicle is released from the factory.

Moreover, maintaining proper functionality throughout a vehicle’s lifespan necessitates additional control measures during periodical technical inspections (PTI). To address these requirements effectively, Dürr and Rohde & Schwarz have collaborated on a joint project that integrates the patented x-road curve multi-function roll test stand from Dürr with the new RadEsT radar target simulator and the open-source simulation platform CARLA from Rohde & Schwarz.

The combination of these technologies creates a virtual environment tailored specifically for the camera and radar sensors installed in the test vehicle. This setup allows for the over-the-air (OTA) simulation of various inspection scenarios without physical contact with the vehicle. Critical situations, such as unintended lane departures and sudden braking or lane changes by other vehicles in front of the test vehicle, can be simulated to assess the vehicle's response accurately.

The 4WD x-road curve enables unrestricted driving with steering movements, facilitating cornering maneuvers without altering the test vehicle. Laser measurement technology tracks the front wheels’ position and steering angle, while swiveling front double roller units automatically adjust for any angular differences to maintain the vehicle's centering on the test stand, even at high speeds.

RadEsT, the radar target simulator developed by Rohde & Schwarz, is designed to withstand external factors, ensuring consistent performance in production and workshop environments. Its precision and repeatability make it a valuable tool for conducting accurate assessments in real-world conditions, particularly in ADAS and autonomous vehicle testing.

Furthermore, the open-source platform CARLA offers vehicle manufacturers and PTI organizations flexibility and cost-saving opportunities for scenario selection. The recent upgrade of the CARLA simulator to Unreal Engine 5 is expected to enhance modeling, simulation realism, and performance, especially for over-the-air camera simulation via monitors.

By leveraging the innovative testing solutions provided by the x-road curve multi-function roll test stand, the radar target simulator RadEsT, and the CARLA platform, manufacturers can evaluate the full functionality of automated and autonomous vehicles cost-effectively. This comprehensive approach ensures proper operation during production and throughout the vehicle's lifespan, ultimately enhancing vehicle safety and performance.
