A method of controlling torque in an all-wheel-drive vehicle limits the duration of loss of traction. During wheel slip events, a controller reduces the commanded torque from a driver demanded level. The controller calculates a normalized wheels speed for each wheel based on a measured yaw rate, measured wheel speeds, and calculated wheel diameters. The controller determines the end of the wheel slip event by comparing the normalized speeds of each while to one another.
