Abstract
A limited slip differential (LSD) transfers a torque from an engine to left and right wheels of a vehicle. A current angle of a steering device is determined. Rotational speeds of 5 the left and right driven wheels are also determined. A current wheel slip of is calculated as a difference between the rotational speeds of the left and right wheels. Maximum and minimum allowed wheel slips are calculated as a function of the current steering angle. The LSD is controlled so that the current wheel slip stays in a range between the maximum and minimum allowed wheel slips. To this end, the LSD is loaded if the wheel slip falls outside of the range 0 between the maximum and minimum allowed wheel slips.
