ABSTRACT:
In a method of providing a desired output torque for an internal-combustion engine a desired air mass-flow value or a desired load value is determined from a desired output torque value in dependence on the engine speed and the throttle-valve opening angle, and the measured actual value is adjusted to the respective desired value by control of the throttle-valve opening angle. A conversion between load and air mass flow takes place by means of a load filter which compensates for the deviations, occurring in dynamic operating states, of the measured air mass flow from the air mass flow actually flowing into the combustion chamber of the engine and a transition between the two regulating methods can take place continuously or in a switched manner.
