Abstract
The invention relates to a method for monitoring the proper functioning of at least one first and a second component () of a vehicle drive train (). The first and the second component () each have an effect on the torque applied to the driveshaft () and are controlled for this purpose by a test signal (). The test signals () are predetermined such that the effects of the first and the second component () onto the torque applied to the driveshaft () cancel each other out if the first and the second component () function properly. When the components () function properly, the traveling comfort is not disturbed by an unexpected torque increase or torque decrease during the carrying out of this method. Any perturbation of the vehicle drive train () is therefore also avoided.
