This paper deals with the description of current and future vehicle technology related to yaw moment control, anti-lock braking and traction control through the employment of effective torque vectoring strategies for electric vehicles. In particular, the adoption of individually controlled electric powertrams with the aim of tuning the vehicle dynamic characteristics in steady-state and transient conditions is discussed. This subject is currently investigated within the European Union (EU) funded Seventh Framework Programme (FP7) consortium E-VECTOORC, focused on the development and experimental testing of novel control strategies. Through a comprehensive literature review, the article outlines the stateofthe-art of torque vectoring control for fully electric vehicles and presents the philosophy and the potential impact of the E-VECTOORC control structure from the viewpoint of torque vectoring for vehicle dynamics enhancement. Furthermore, the low response time and high controllability of electric motor drives can bnng significant benefits for the feedback control of vehicle yaw rate and sideslip angle in emergency conditions. However, the advantages of the high frequency range of torque modulation achievable with electric drive units may be compromised by the adoption of in-board motors, since the influence of the torsional dynamics of the powertrain and its mounting system should be taken into account for the implementation of TC/ABS systems.
