Abstract

A method of modifying the motion of an output-varying control element of an internal combustion engine for a motor vehicle includes detecting the position of the gas pedal and, depending on the position of the gas pedal, determining a control parameter for the output-varying control element. For a particular setting of the output-varying control element the output increment per cycle is prospectively determined, at least as a function of operating parameters of the engine, and from this optimal value and the control parameter determined according to the gas pedal position, a parameter is computed for the output varying control element in the ensuing cycles.
