According to the present invention, a desired change of a time derivative of dynamic torque ( Tq fw ), which is provided to an output shaft from an engine in a vehicle, from a current value to a new desired value is determined. A current rotational speed difference (Δω pres ) is determined between a first end of the powertrain in a vehicle, rotating with a first rotational speed (ω1), and a second end of the powertrain, rotating with a second rotational speed. The first rotational speed (ω1) is then controlled on the basis of the desired value of the time derivative for the dynamic torque ( Tq fw ), a spring constant (k) related to a torsional compliance in the powertrain, and the determined current rotational speed difference {Δω pres ). Through control of the first rotational speed, the current value for the time derivative for the dynamic torque is also indirectly controlled towards the desired value. |
