ABSTRACT:
A device for controlling a turbocharger with a rotary electric machine detects, at all times, the rotational speed of an engine of a motor vehicle and an amount of depression of the accelerator pedal to monitor present running conditions of the motor vehicle. A required boost pressure subject to the running conditions is determined, and if a difference between the required boost pressure and a present boost pressure is greater than a prescribed value, the device determines that the motor vehicle is running under conditions which require quick acceleration. The device then drives the rotary electric machine coupled to the rotatable shaft of the turbocharger as a motor to increase the speed of rotation of the turbocharger for a quick buildup of the boost pressure.
