Nowadays, the integration of various electronic systems in the chassis of vehicles for active safety purposes is widespread and ever increasing in the automotive industry. Motivated by this trend, this master thesis aims at developing an active rear-wheel steering (RWS) controller implemented on a virtual vehicle based on the know-how of Danisi Engineering company, headquartered in Nichelino (TO). For the controller’s creation, various classical and optimal control methods are explored and realized. An initial review displays the growing interests from major car manufacturers and researchers since the eighties regarding RWS systems’ realization and their control design. Benefits in terms ofmaneuverability and stability are obtained from proposals of RWS control based on different theories for various typologies of RWS systems.
