The purpose of this thesis work is to design a Traction Control System algorithm for an all-wheel-drive hybrid vehicle. Generally, the control aim is to prevent the driven wheels from spinning, in order to guarantee vehicle stability, especially on slippery roads. In this specific case, the control logic has to be also adapted for three vehicle driving modes: Comfort, Wet and Sport. First of all, the 14-degrees-of-freedom vehicle model is implemented on the VI-CarRealTime software and its overall dynamic performances are evaluated. The vehicle object of this study is a high performance one, equipped with two independent electric motors on front wheels and an internal combustion engine on rear axle.
