Abstract

The use of model-based controller or fault diagnosis systems in automotive control requires reliable dynamics models. The reliability consists in accurate prediction of the vehicle's behavior, in order to evaluate current driving situations. Model parameters have to be precisely identified. This depends on the model's capability to reproduce the complex dynamics of the real system, by remaining as simple as possible, for online computation. in this article, a practical approach of modelling vehicle dynamics is presented. Conventional simplifications are removed by coupling lateral and roll motion. Besides, nonlinear tire characteristic is pre- sented. The accuracy and performance of the identified model is demonstrated by tests on real automotive systems.
