Abstract
A method and a device for regulating the boost pressure of an internal combustion engine having a multiflow air system, which enables both rapid regulation and limitation of the exhaust gas back pressures. The multiflow air system includes a multichannel air supply and a corresponding multichannel exhaust gas discharge, each exhaust gas channel having an exhaust gas turbocharger. A manipulated variable for a specified boost pressure to be set is determined as a function of the actual exhaust gas back pressure prevailing in the particular exhaust gas channel.
