Yaw Control is a common topic on high performance race cars vehicle dynamics. Compared to Yaw Control for passenger cars, the application to high-performance vehicles is mainly focused on improving drivability, reactivity and performance through the partial or total achievement of a desired cornering behaviour, obtained through vehicle states tracking. The subject of this analysis is the development of a Yaw Control for the Formula Student (FS) 4-Wheel-Drive (4WD) electric race car of Squadra Corse PoliTo. The prototype is equipped with four electric motors, independently controlled, driving one wheel each, guaranteeing high flexibility in torque control. Thus, in this application, Yaw Control is obtained exploiting Torque Vectoring (TV) strategy, so obtaining a torque unbalance between left and right wheels during cornering, to help the vehicle behave in the desired way.
