Abstract

A method for activating a boost pressure control for an internal combustion engine, which contains, in a through-flow direction, a compressor, a charge air line, a throttle valve, an intake manifold, at least one combustion chamber and a turbine speed-coupled to the compressor, an aperture of the throttle valve being controllable, a driving of the turbine being controllable by an exhaust gas flow, and the method including: predefining a setpoint intake manifold pressure; calculating a simplified inverse flow characteristic of the throttle valve; calculating a pseudo setpoint aperture of the throttle valve, based on the simplified inverse flow characteristic and the setpoint intake manifold pressure; and controlling the driving of the turbine, based on an exceeding of a maximum aperture of the throttle valve by the pseudo setpoint aperture of the throttle valve.
