Expensive test drives on the road are no longer needed, but can be simulated on a test stand providing reproducible results independent of weather conditions.

Determination of the wheel traction for the the total vehicle. (All components are already installed). The roll and flex losses are then compensated.

The test stand consists of 4 roller pairs, (roller sets) each non-positively connected to a AC motor unit. The roller sets are synchronized via a so-called “electrical shaft”.

Each motor unit can be actively driven or braked.
