  • Patent number: 10184390
    Abstract: A method of operating an automotive system having an internal combustion engine equipped with an electric compressor and a turbocharger having a turbocharger compressor is disclosed. A surge threshold line and a pre-surge threshold line in a turbocharger compressor map are defined as a function of a turbocharger compressor pressure ratio and mass flow rate. The pre-surge threshold line is defined in terms of greater mass flow values for each corresponding pressure ratio value of the surge threshold line. The position of a turbocharger compressor working point in the turbocharger compressor map is monitored as a function of the turbocharger compressor pressure ratio and mass flow rate. When an increased torque request is detected, the electric compressor is activated to assist the turbocharger compressor in delivering the requested torque when the turbocharger compressor working point crosses the pre-surge threshold line in a direction towards the surge threshold line.
