Patent abstract
In a method for limiting a boost pressure of an internal combustion engine which is supercharged by the compressor of an exhaust gas turbocharger including a control unit in which a desired boost pressure value is compared with a limiting value and when the desired boost pressure value exceeds the limiting value, the boost pressure is limited to the limiting value, and the limiting value is determined by a simulation model in the form of a group of a characteristic curves established as a function of an existing operating state of the internal combustion engine, a temperature, a pressure (p1), and a air mass flow rate which occur upstream of a compressor of the exhaust gas turbocharger.
