Regulation method for turbocharged internal combustion engine

摘要

The invention relates to a method for controlling a super-charged internal combustion engine. According to said method, boost pressure reference variables are adjusted to predetermined boost pressure controlled variables by adjusting the component of an adjustable charger which influences the boost pressure in accordance with a predetermined set of rules. The set of rules uses a PID controller in order to monitor the boost pressure control in a super-charged internal combustion engine using simple means and, optionally, to indicate a malfunction. The level of integration in the integration component of the PID controller is compared with a predetermined tolerance band and an error signal is generated if the level of integration lies outside the tolerance band.
