ABSTRACT:
In a turbocharger equipped with a motor/generator, the motor/generator gradually decreases its generator output without shifting abruptly from generation mode to motor mode when a vehicle starts accelerating during cruising at a constant speed or runs along an upward slope, thus preventing abrupt increases in the loading on an engine. A control system for a motor/generator equipped turbocharger which is disposed across an exhaust conduit of an engine and includes a rotating shaft thereof on which a motor/generator is mounted is provided having a controller for, when the motor/generator is actuated as a motor, feeding the motor/generator with a supply of power from a battery, and when the motor/generator is actuated as a generator, converting an alternating current, high voltage form for charging the battery and also to a three-phase alternating current form for driving as a motor an alternator which is driven as a generator by the engine, an engine revolution sensor, an accelerator opening sensor, and an engine boost pressure sensor. More specifically, the control system comprises a calculating device for calculating a target boost pressure from the engine revolution sensor and the accelerator opening sensor, a first judging device for determining that the action of the engine is an acceleration mode when a difference between the target boost pressure and an actual boost pressure is smaller than a first predetermined value, and a device for decreasing the generator output of the motor/generator when the motor/generator is actuated as the generator during the acceleration mode judged by the first judging device.
