摘要:
A method of and apparatus for operating a supercharger for an automotive engine is disclosed. The supercharger has: an input shaft for coupling to an engine crankshaft, and coupled to the rotor of a first electrical machine and a first component of an epicyclic gear train; and an output shaft connected to a compressor and a second component of the epicyclic gear train; wherein the third component of the epicyclic gear train is connected to the rotor of a second electrical machine. The first electrical machine is selectively operable to supply electrical energy to the second electrical machine. The method includes the steps of: (a) calculating a required speed of the second electrical machine that would give rise to a required pressure at an outlet of the compressor; and (b) setting the speed of the second electrical machine to the calculated required speed.

A variable speed hybrid electric supercharger assembly is controlled to regulate an adaptive state of charge of an energy storage device and/or to boost an engine based on a performance mode selected by a driver. In one example, a reference state of charge is determined based upon driving characteristics of a vehicle and compared to an actual state of charge of the energy storage device. If the difference indicates a deficit, an operation mode is selected to regenerate the energy storage device. In another example, a planetary gearing arrangement between an engine and an electric motor is configured to increase or decrease power transferred to the supercharger by the engine based upon the performance mode selected by the driver.
