Quantifizierte Validierung des Hohenheimer Reifenmodells für fahrdynamische Untersuchungen

The Hohenheim Tyre Model was developed for investigations regarding driving dynamics as well as driving comfort. Before its application as development tool, it has to be thoroughly validated. Regarding vertical and lateral investigations, the model is validated by comparing simulation results with measurements on single tyres and on whole vehicles. A single wheel tester and an equipped test tractor are used to determine the forces acting between the tyre and the road surface as well as the driving conditions during certain manoeuvres. The conducted road tests are reproduced using multi-body simulation models (MBS) simulation models in connection with the Hohenheim Tyre Model. By using separate evaluation metrics regarding the magnitude and phase behaviour, a good correlation between measurements and simulation results is shown.
