Abstract

A device for controlling an internal combustion engine having an arrangement for recording operating parameters of the internal combustion engine, such as engine speed, load, and coolant temperature; an arrangement for providing a signal related to a desired drive torque of the internal combustion engine (engine torque) as a function of the recorded performance quantities; and an arrangement for converting the engine torque into control signals for at least one of the variables air supply or fuel supply to the internal combustion engine, as a function of the coolant temperature toot and of a pre definable maximum allowable coolant temperature limit tom-tom, a torque control value being determined which ultimately determines the allowable engine torque.
