  • Patent number: 9605607
    Abstract: A method is provided for controlling a filling (rl) of an internal combustion engine (2) including the camshaft phase adjustment in the case of a predefined setpoint filling (rlsol), including the following steps: carrying out the filling control based on an indicated pressure difference for obtaining a control variable (?Fuereg) for setting an air mass supply to the internal combustion engine (2); and ascertaining the indicated pressure difference (?pSR) as a difference between a predicted intake manifold pressure (psrpred) and an actual intake manifold pressure (pSR), the predicted intake manifold pressure (psrpred) corresponding to an intake manifold pressure which is necessary for reaching the setpoint filling (rlsol) at an aspiration curve which is predicted for a predefined time constant (?).

  • Publication number: 20140150425
    Abstract: A method for controlling an exhaust gas recirculation system of an internal combustion engine includes: determining a setpoint power to be output by the internal combustion engine; and limiting an exhaust gas flow conducted through the exhaust gas recirculation system based on the setpoint power.
