Durr and Rohde & Schwarz collaborate on ADAS/AD functional testing for EOL and PTI

08/28/2024

Road safety is a key challenge for future mobility, especially for automated and autonomous vehicles. Ensuring the continued functionality of advanced driver assistance systems (ADAS) and autonomous driving (AD) features is critical for long-term vehicle safety and performance. Therefore, manufacturers of vehicles equipped with these features require certification, either from a third party, authority or by self-certification. A vehicle-in-the-loop (VIL) test can validate the correct operation of all ADAS/AD functions in the end-of-line (EOL) and ensure conformity of production (COP) before a vehicle leaves the factory. In addition, maintaining proper functionality throughout a vehicle’s lifespan requires additional control measures during periodical technical inspection (PTI).

To address these additional requirements in the EOL and PTI process, Dürr and Rohde & Schwarz initiated a joint project incorporating Dürr's patented x-road curve multi-function roll test stand, Rohde & Schwarz’ new RadEsT radar target simulator and the open-source simulation platform CARLA. The combination creates a virtual environment specifically for the camera and radar sensors installed in the test vehicle, allowing for the OTA simulation of different inspection scenarios without touching the vehicle. These scenarios include critical situations such as unintended lane departures and other vehicles braking suddenly or switching lanes directly in front of the test vehicle. The test vehicle must react promptly to changes in the VIL simulation and, if necessary, trigger the automated lane-keeping systems (ALKS) or advanced emergency braking systems (AEBS), for example, to pass inspection.
