ABSTRACT:
The invention relates to a method for compensating steering-torque disturbances caused by unequal torque distribution at the front wheels of a motor vehicle with front-wheel drive or all-wheel drive and an active differential. In this arrangement, the magnitude of the steering-torque disturbance is determined from the torque distribution, the total torque and the steering lever and a compensation torque is exerted on the steering system by means of an active steering-servo device.
