Abstract
A limited slip differential (LSD) is mounted on a driven axle of a vehicle to drive left and right wheels. To control the LSD, a current input torque applied to the LSD is determined and a predicted engine torque is determined based on an accelerator control position. A current average speed of the left and right wheels is also determined. A preload is applied to the LSD. The preload is determined based on the predicted engine torque and to the current average speed of the left and right wheels.
