Abstract:
In every driving condition powertrain and vehicle dynamics deeply influence each other. The main role of powertrain influence is played by the differential, which transmit the driving torque mainly with respect to wheel kinematics. Semi-active controlled versions of this device have been recently conceived to improve vehicle handling basing their function on the wheels kinematical conditions. On the other hand, active differentials allow to generate the most appropriate yaw moment controlling both the amount of transferred torque and its direction. The application presented in this the paper aims at enhancing the dynamic behavior of a rear-driven sport vehicle by creating the required yaw moment through brakes actuation and throttle control; the examined car is equipped with free differential, thus the proposed system does not require the introduction of additional devices. Performance measures relate to both open-loop and closed-loop driving demands, and include limit handling maneu
