Passenger vehicle behavior modeled by Power Flow using different mathematical tire models

Resumo

Ground Vehicles can be approached as a set of integrated subsystems, with cause-effect relationships. Through the Power Flow Modeling approach, each of these subsystems can be interpreted as a black box, and interrelated with the others in a modular way, as long as causalities are respected. This work aims to take advantage of the modularity of the automobile interpreted as a set of integrated subsystems and evaluate the influence of mathematical tire models on its acceleration and braking behavior. Each of the subsystems is mathematically modeled in individual blocks that are then integrated, without loss of causality, in MATLAB/Simulink® software. The purpose is to provide a fully modular vehicle model, taking advantage of this Power Flow feature, in an open-source code. Furthermore, Inverse Problems are applied to estimate parameter values of the Burckhardt and Dugoff mathematical models in order to obtain similar behaviors of the corresponding tire model by the Magic Formula.
