Abstract
The power-assisted supercharger () includes: a turbocharger () in which a turbine () is rotationally driven by exhaust gas () from an engine (), a compressor () rotationally driven by the turbine compresses intake air () and supplies the intake air to the engine; an electric motor () connected to a rotary shaft () connecting the turbine and the compressor, the electric motor to add rotational force to the turbocharger; and a motor controller () to control a drive current (I) to the electric motor required for an assist operation for the turbocharger, by open loop, based on an accelerator opening degree (A) of the engine and a rotational speed (NE) of the engine. In this power-assisted supercharger, a turbo lag can be reduced by itself, power consumption can be small even in a range in which the rotational speed is high, malfunctions or unnecessary power consumption can be prevented, a control system can be simplified, and the installation space and the weight thereof can be small.
