Patent ID: 6922996

Claim:
A method for controlling an electrically driven compressor in an internal combustion engine with an exhaust gas turbocharger comprising: determining turbine power instantaneously available; determining compressor power instantaneously required, when a required compressor power is greater than the available turbine power of the exhaust gas turbocharger, a pressure to be generated by an electrically driven compressor is determined in an inverse compressor model; determining, using the pressure to be generated by the electrically driven compressor, the required powers of the turbine of the exhaust gas turbocharger and the electrically driven compressor; and controlling the electrically driven compressor in accordance with the power required, wherein, when the electrically driven compressor is connected, a charge pressure control activates the turbine with a maximum power and controls the charge pressure by adjusting the power of the electrically driven compressor.
