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.


Connect existing elements within the vehicle development process for early, cost-saving decisions.

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)

4 tests -1 day

4 tests -10 min
