Identification method of longitudinal tyre characteristics based on real road driving

Nowadays, the tyre parameters are determined by measurements on the tyre test rig and manually adapted to real road conditions before they are used for a credible vehicle dynamic simulation. This requires relevant expertise of the user or it must be accepted that results of the simulation can differ significantly from the behaviour of the tyre on the track. At this point the question arises how it is possible to make the actual procedure of tyre model parameterisation more efficient and safer. This paper illustrates a new procedure to adapt MF-Tyre model parameters to real road conditions. It replaces the necessity of the elaborate manual modification of the MF-Tyre model parameters. Beyond this, basic tyre properties can be identified without the need of tests at the test rig. Studies have shown that the adaptation of the basis MF-Tyre parameter set already leads to a significant improvement of the simulation quality.
