ABSTRACT:
A device for controlling a turbocharger having an electric rotary machine confirms present running conditions of a motor vehicle by detecting, at all times, the engine speed, the engine load, and the amount of depression of an accelerator pedal while the motor vehicle is running, and determines whether the electric rotary machine is to operate in a generator mode or a motor mode. If the electric rotary machine is to operate in the motor mode, appropriate electric power is supplied to the electric rotary machine based on the engine load, the accelerator pedal depression, and the speed of rotation of the turbine of the turbocharger, for increasing the speed of rotation of the turbocharger to quickly increase the boost pressure developed by the turbocharger.
