AVL, Rohde & Schwarz join forces for XiL tests systems
The automotive engineering company AVL and the measurement technology Rohde & Schwarz specialist are expanding their toolchain for vehicle testing in the area of radar technology. This should open up new possibilities for customers to test radar-based ADAS functions and validate autonomous driving functions on a vehicle-in-the-loop test bench. This will allow complex driving scenarios to be generated and tested.

The validation of complex Advanced Driver Assistance Systems (ADAS) and Automated Driving (AD) functions requires extensive functional and non-functional testing. This affects, among others, emergency braking, adaptive distance and speed control and autonomous driving on the motorway (highway chauffeur) under all possible driving scenarios and environmental conditions. If this validation is carried out on the road, risks may be associated with it. Furthermore, carrying out conventional practical tests on the road is often simply impossible in view of the new challenges of automated driving. This makes it necessary to virtualise the test methods with an X-in-the-Loop (XiL) approach - e.g. with AVL's Drivingcube.

The Drivingcube supports both the simulation and testing of ready-to-drive vehicles on a chassis dynamometer and powertrain test bench. It opens a new way to accelerate the validation and approval process of ADAS and AD systems. Key concept of this solution is the operation of the real vehicle in a virtual environment, taking into account all components of the sense-plan-act chain. The connection of the virtual environment with the sensors actually installed requires state-of-the-art simulation technology. Especially on a test bench, the general conditions are completely different from those in an isolated sensor laboratory.
