A method for limiting the amount of torque biased to a high µ wheel of a vehicle comprises processing clutch torque data to determine an electronic limited slip differential clutch torque limit, processing wheel speed data to generate µ slip data, comparing the generated µ slip data to threshold µ slip data. When the generated µ slip data is greater than the threshold µ slip data, the method comprises reducing the electronic limited slip differential clutch torque limit by a predetermined ratio.
