<p>A control method of the wastegate valve (16) in an internal combustion engine (1) turbocharged by a turbocharger (12); the control method provides the steps of: determining a target boost pressure (P obj ); determining an actual boost pressure (P); determining a target position (WG obj ) of the wastegate valve (16) by means of a control strategy which uses the target boost pressure (P obj ) and the actual boost pressure (P); and differentiating the control strategy as a function of a target boost jump (”P obj ), i.e. the difference between the target boost pressure and the atmospheric pressure, to determine the target position of the wastegate valve through a first control strategy and through a second control strategy.</p> |
