A method for controlling a speed difference between speed of wheels of a front axle and speed of wheels of a rear axle of a four-wheel drive vehicle. The method: determines an initial speed difference set point based on the speed of the vehicle; determines one or more intermediate speed difference set points based on one or more operational parameters of the vehicle; modulates the initial speed difference set point based on the intermediate speed difference set points to obtain a final speed difference set point; measures the speed difference and compares the measured speed difference with the final speed difference set point; and controls the measured speed difference, so that the measured speed difference reaches the final speed difference set point.
