Embodiments of the present disclosure relate to a method and device for valve travel switching control of an internal combustion engine supercharged by an exhaust-gas turbocharger having a wastegate valve. This valve travel switching control includes: determining the current sensitivity of the charge pressure at a current operating point, at which a current valve travel, a current wastegate valve position and a current charge pressure are present, to changes in the wastegate valve position; determining the minimum valve travel necessary to set a desired operating point, taking into account the determined current sensitivity of the charge pressure; and switching the valve travel if the minimum valve travel necessary to set the internal combustion engine to an extended range with respect to the desired operating point differs from the current valve travel. By means of these measures, the fuel saving operating range of the internal combustion engine is enlarged.
