  1. Tyre parameter identification from road tests on a complete vehicle Dario Lo Conte, PME-EM

  2. Outline Centro Ricerche Fiat Problem description Introduction to optimization TyreEstimator Conclusions and recommendations

  3. CRF • Centro Ricerche Fiat • Part of Fiat Group • 850 FTE • Scope

  4. Problem description • Experimental test data differs from vehicle model data

  5. Problem description • Reasons • Different tyre testing conditions • Different measurement method

  6. Problem description Vehicle model Tyre model

  7. Problem description Current approach Validation suspension Manual tuning of tyre parameters Drawbacks Takes some days of work Inconsistent

  8. Problem description “To improve the characterization of tyres from road tests an application needs to be developed that automates the identification of tyre model parameters.”

  9. Optimization Making things better Get the best out of a calculation Generating more profit Provides a systematic approach for problem solving

  10. Optimization Euclides Calculate derivative Objective function Design variables Constraints x 8-x 8-x x

  11. Optimization Local/Global minima Algorithms
