<p>An arrangement for regulating the torque transmitted by friction type gear shifting elements whereby, at every point in time throughout a previously specified time duration of a gear shifting operation, the clutch torque which is necessary at that point in time and is defined as a minimum torque, is computed utilizing measured values of an input and output rotational speed of a change-speed transmission or a gearbox, as well as measured values of an operating pressure of the friction-type gear shifting elements. At the minimum torque the relative rotational speed of the parts of the friction-type gear shifting elements, for example, parts of a friction-type clutch, a difference between an input and output speed of the change-speed transmission or gearbox remains constant. At the same time, an additional torque is computed in accordance with a prespecified function. The operating pressure of the friction-type gear shifting elements is then adjusted analogously to an output signal U, with the output signal being an analog of a sum of the necessary torque and additional torque.</p> |
