Patent ID: 7770392

Claim:
A method for controlling an internal combustion engine having at least one exhaust gas turbocharger with at least one exhaust gas turbocharger actuator, an exhaust gas recirculation device with an exhaust gas recirculation valve, wherein the method comprising the steps of: determining by an exhaust gas turbocharger controller a feedback control actuating variable exhaust gas back pressure as a function of a setpoint boost pressure and an actual boost pressure; determining by an exhaust gas recirculation controller a feedback control exhaust gas recirculation actuating variable, as a function of a setpoint mass air flow and an actual mass air flow; determining by a decoupling unit a decoupling mass flow in an exhaust gas tract downstream of a branch-off of the exhaust gas recirculation device which is dependent on the feedback control exhaust gas recirculation actuating variable, and determining by a conversion unit an actuating signal for the exhaust gas turbocharger actuator as a function of the feedback control actuating variable exhaust gas back pressure and the decoupling mass flow.
