Patent ID: 8245802

Claim:
An automotive hybrid engine assist system comprising: a generator-motor that is coupled to an internal combustion engine so as to act as a starter motor to start said internal combustion engine during starting of said internal combustion engine, and so as to be driven by said internal combustion engine to generate three-phase alternating-current power after starting of said internal combustion engine; a battery that constitutes a power source for a direct-current load and for starting; a turbocharger comprising: a compressor that is disposed in an induction system of said internal combustion engine, and that compresses intake gas; a turbine that is mounted coaxially onto a rotating shaft of said compressor, and that is disposed in an exhaust system of said internal combustion engine; and an electrical rotary machine that is mounted coaxially onto said rotating shaft; an inverter that is connected by wiring to three-phase power terminals of said generator-motor and three-phase power terminals of said electrical rotary machine, and that converts said three-phase alternating-current power that is generated by said generator-motor into direct-current power and supplies said direct-current power to said battery when connected to said generator-motor, and that converts direct-current power from said battery into three-phase alternating-current power and supplies said three-phase alternating-current power to said electrical rotary machine when connected to said electrical rotary machine; and an electric power direction change-over switch that is disposed in a path of said wiring, and that switches connection of said inverter to said generator-motor or to said electrical rotary machine.
