Method for ascertaining a cylinder charge of an internal combustion engine achievable within a certain time period

A computer-readable storage medium storing a computer program for ascertaining a cylinder charge of an internal combustion engine of a vehicle achievable within a predefinable time period, the computer program, when executed by a control unit, causing the control unit to perform:

• ascertaining a charging behavior of an air system, the air system including at least one of an intake manifold, and a charge air line of the combustion engine, the charging behavior being ascertained within the time period as a function of instantaneous operating variables of the internal combustion engine, and a value which characterizes a dynamic of a final control element of the air system, the final control element including a throttle valve;
• and
• ascertaining the achievable cylinder charge within the time period as a function of the ascertained charging behavior of the air system, and as a function of a charge buildup by a charger of the internal combustion engine.
