Abstract

A method for controlling an internal combustion engine with variable valve lift has the following steps: Determining the pressure in the intake manifold; predetermining the pressure in the intake manifold following a changeover of the valve lift; determining a selection criterion for a valve lift to be set; and setting that valve lift at which the higher pressure is reached in the intake manifold, unless the selection criterion requires the use of the valve lift at which the lower pressure is reached in the intake manifold.
