<p>A device for controlling a turbocharger (2) with a rotary electric machine (3) detects, at all times, the rotational speed (15) of the engine on a motor vehicle and the amount of depression of the accelerator pedal (13) to confirm present running conditions of the motor vehicle. A required boost pressure which is required under the confirmed running conditions is determined, and if the difference between the required boost pressure and the 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 (3) coupled to the rotatable shaft (23) of the turbocharger (2) as a motor to increase the speed of rotation of the turbocharger (2) for a quick buildup of the boost pressure.</p> |
