This paper presents a semi-active differential, denoted by MRF LSD (Magneto-Rheological Fluid Limited Slip Differential) that allows to bias torque between the driving wheels.It is based on the Magneto-Rheological (MR) fluid employment, by which it is possible to change, in controlled manner, the internal friction torque and, consequently, the torque bias ratio.The device is an adaptive one and allows to obtain an asymmetric torque distribution in order to improve vehicle handling.The device modelling and the control algorithm, realized for this activity, are described. The illustrated results highlight the advantages that are attainable regarding directional behaviour, stability and traction for a front wheel drive (FWD) vehicle. A comparison with a traditional passive limited slip differential has been conducted.
