Abstract
A control method for a supercharged internal combustion engine wherein actual supercharging pressure values are adjusted to prescribed desired supercharging pressure values by setting a variable component and influencing the supercharging pressure of a supercharger in accordance with a prescribed control law. In order to monitor the control of supercharging pressure in a supercharged internal combustion engine with the aid of simple means and, if appropriate, to display a malfunction, use is made as control law of a PID controller, the integration component is compared in the integration element of the PID controller with a prescribed tolerance band, and a fault signal is generated if the integration component is outside the tolerance band.
