Zusammenfassung:A method and a system for control of a torque Tqdemand requested from an engine in a vehicle, wherein the engine provides a dynamic torque Tqfw in response to the torque Tqdemand. Control of the requested torque Tqdemand is performed such that the control provides a desired value Tqfw_req for the dynamic torque and/or a desired derivative Tqfw_req for the dynamic torque. This is achieved by basing the control on at least one current value Tqfw_pres for the dynamic torque, on one or several of the desired value Tqfw_req and the desired derivative Tqfw_req for the dynamic torque, and on a total delay time tdelay-total elapsing from determination of at least one parameter value, to when a change of the dynamic torque Tqfw based on the determined at least one parameter value, has been effected.
