Contributor De Vries, E.J.H. (mentor) Faculty Mechanical, Maritime and Materials Engineering Department Precision and Microsystems Engineering Date 2010-04-29 Abstract Vehicle manufacturers notice a difference between the tyre behaviour observed in road tests with a complete vehicle and the behaviour of the tyre as provided by the tyre manufacturers. To improve the tyre characterization and avoid appointing its behaviour each time using trial-and-error, Centro Ricerche Fiat requests the development of an application that can identify the tyre parameters consistently and automatically. This thesis describes the process of developing the TyreEstimator, the application written for the identification of the tyre parameters. The application is built to minimize the difference between the vehicle model data and the experimental data using an optimization algorithm. Two vehicle models are implemented to identify the tyre parameters. The tyre behaviour is described using the Magic Formula tyre model. Due to the sensitivity of the optimization problem, the application is constructed to cope with different options for finding the tyre parameters. Afterwards an empirical analysis, using the TyreEstimator, is performed. This results in an option set for each vehicle model, which approaches the tyre behaviour best.
