Abstract

While VDC systems usually operate on the engine torque and on brake pressures, new automotive applications try to use semi-active or active differentials in order to optimize the torque distribution on the wheels for traction maximization, driving comfort, stability and safety of the vehicle. The system presented in the paper comes out from the cooperation of Ferrari, MAGNA STEYR and Politecnico di Milano in the development of a semi-active differential (named EDIFF) implemented in the new Ferrari F430. In the paper a description of either the vehicle dynamic control strategy, its development, and of the experimental results are given.
