Zusammenfassung:A control method of a butterfly valve of an internal combustion engine, when said internal combustion engine is running, wherein said butterfly valve is controlled by means of a control signal, indicative of an angular position of said valve, the method comprising a step of applying a first limiting filter of a gradient of said control signal, when a ratio between a target pressure downstream of the butterfly valve and a measured pressure upstream of the butterfly valve is greater than a first predetermined threshold.
