Dürr and Rohde & Schwarz have developed a concept for over-the-air vehicle-in-the-loop tests for driver assistance systems and autonomous driving. According to the companies, it is suitable for vehicle testing at the end of the assembly line or regular technical vehicle monitoring.

In the project, the companies combine Durr's "x-road curve" dynamometer, Rohde & Schwarz's "RadEsT" radar target simulator, and the open-source simulation platform "CARLA". The combination creates a virtual environment for the camera and radar sensors installed in the test vehicle, Durr writes in a press release.

Simulate test scenarios contact-free.

In this environment, companies can simulate test scenarios over-the-air without modifying the vehicle. The scenarios include critical situations such as unintentional lane departure, sudden braking of other vehicles or their lane change directly in front of the test vehicle.

The vehicle to be tested must react to changes in the simulation and, if necessary, activate an automatic lane-keeping system or emergency braking assistant in order to pass the test.
