Method and device for controlling a filling in a cylinder of an internal combustion engine

A device for controlling a filling of an internal combustion engine having a camshaft phase adjustment in the case of a predefined setpoint filling, comprising:

• an arrangement configured for:
• performing the filling control based on an indicated pressure difference for obtaining a control variable for setting an air mass supply to the internal combustion engine;
• and
• ascertaining the indicated pressure difference as a difference between a predicted intake manifold pressure and an actual intake manifold pressure, the predicted intake manifold pressure corresponding to an intake manifold pressure which is necessary for reaching the setpoint filling at an aspiration curve which is predicted for a predefined time constant.

A computer readable medium having a computer program, which is executable by a processor, comprising:

• a program code arrangement having program code for controlling a filling of an internal combustion engine including a camshaft phase adjustment for a predefined setpoint filling, by performing the following:
• performing the filling control based on an indicated pressure difference for obtaining a control variable for setting an air mass supply to the internal combustion engine;
• and
• ascertaining the indicated pressure difference as a difference between a predicted intake manifold pressure and an actual intake manifold pressure, the predicted intake manifold pressure corresponding to an intake manifold pressure which is necessary for reaching the setpoint filling at an aspiration curve which is predicted for a predefined time constant.

An electronic control unit, comprising:

• an electronic storage medium having a computer program, which is executable by a processor, including a program code arrangement having program code, by performing the following:
• performing the filling control based on an indicated pressure difference for obtaining a control variable for setting an air mass supply to the internal combustion engine;
• and
• ascertaining the indicated pressure difference as a difference between a predicted intake manifold pressure and an actual intake manifold pressure, the predicted intake manifold pressure corresponding to an intake manifold pressure which is necessary for reaching the setpoint filling at an aspiration curve which is predicted for a predefined time constant.
