The challenge
Speeding-up development process by re-using simulation models from different tools from the office concept phase to the hardware testing and validation.
• Mastering new applications: ADAS, RDE, VTMS, calibration etc.
• Connecting existing co-simulation models in an optimal way.
• Using simulation models in HiL and testbed environments.

Reference Project with TÜV SÜDApproaches for Virtual Homologation of HAD/ADAS
Project Target: Common definition, development of showcases, networking with lighthouse projects & committees for standards for the verification, validation & type approval of HAD/ADAS
The most efficient validation will be done by those who will use the best combination!
Proving Ground
very close to the real operation
expensive, high effort, less repeatability
AVL DRIVINGCUBE™
close to real operation, chassis dynos are already established for homologation (emissions)
limited in terms of lateral dynamics
Simulation
fast, flexible and cheap in operation, there are already ESC homologation
processes in simulation is only as good as the model(s)
