Clutch-Controlled Limited Slip Differential

This example shows a comparison of the behavior of an open differential and a clutch-controlled limited slip differential in a typical road condition whereby one of the wheels loses traction while transmitting torque. Limited slip is achieved by augmenting a conventional differential with two friction clutches whose normal pressure is modulated by the driveshaft torque. The clutches act to reduce any asynchronous rotation of the wheels. In the simulation, the uneven road condition is reproduced by decreasing the wheel normal force during vehicle acceleration. The output plots show that the open differential exhibits large differences in wheel angular velocities, while the limited slip differential forces them to rotate almost synchronously.
