Abstract

This study introduces an estimation process for longitudinal and lateral tire road forces, for that an electric vehicle with four in-wheel motors has been implemented. This structure permits to control independently each one wheel so that deals to torque’s control with fast response which represent the best advantage in this kind of vehicles with PMSM which take a dominant position in several systems with variable speed drive because of their, low inertia, high efficiency and no maintenance. The performance of this concept is tested and demonstrated using Matlab/Simulink. The simulation results show that the proposed approach is a promising technique to provide accurate estimations of vehicle dynamic states.
