Abstract

A method for precisely controlling the charge pressure in an internal combustion engine with an exhaust-gas turbocharger is disclosed. According to said method, the output or torque of the turbine is determined based on the outputs or torques of the compressor and the loss on the shaft and the selected set point for the correcting variable for adjusting the charge pressure is determined according to said output or said torque of the turbine.
