Patent ID: 8370047

Claim:
A method of controlling an internal combustion engine comprising: an intake tract, a controllable throttle valve for controlling the air flow rate in the intake tract, a compressor, which is disposed in the intake tract downstream of the throttle valve and by means of which the internal combustion engine may be operated selectively in a charging mode and a non-charging mode, a first pressure sensor, which is disposed in the intake tract) downstream of the throttle valve and upstream of the compressor, a second pressure sensor, which is disposed in the intake tract downstream of the compressor, the method comprising the steps of: calculating a first pressure value in the intake tract downstream of the throttle valve and upstream of the compressor and a second pressure value in the intake tract downstream of the compressor by means of an intake manifold model, acquiring a first reference pressure by means of the first pressure sensor and a second reference pressure by means of the second pressure sensor, determining whether the internal combustion engine is in the charging mode or in the non-charging mode, correcting the intake manifold model in the event of a deviation of the first pressure value from the first reference pressure and a deviation of the second pressure value from the second reference pressure as a function of the charging mode or non-charging mode.
