Abstract
A method for charge pressure control of an internal combustion engine that is an integral part of a drive train, wherein the drive train comprises at least the internal combustion engine, an intake line, an exhaust gas line, and an exhaust gas turbocharger. The internal combustion engine has at least one intake valve that fluidically connects the intake line to a combustion chamber of the internal combustion engine, and at least one exhaust valve that fluidically connects the combustion chamber to a first section of the exhaust gas line. The exhaust gas line has a first section between the combustion chamber and the exhaust gas turbocharger, and a second section downstream from the exhaust gas turbocharger. The exhaust gas turbocharger and/or a bypass that bypasses the exhaust gas turbocharger are/is adjustable. In the method, an opening point in time of the at least one intake valve and a closing point in time of the at least one exhaust valve are taken into account.
