In a turbocharger equipped with a motor/generator (6), 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 increase in the loading on an engine. A control system for a motor/generator (6) equipped turbocharger which is disposed across an exhaust conduit of an engine and includes a rotating shaft thereof on which a motor/generator (6) is mounted is provided having a controller (11) for, when the motor/generator (6) is actuated as a motor, feeding the motor/generator (6) with a supply of power from a battery (10), and when the motor/generator (6) is actuated as a generator, converting an alternating current, high voltage output of the motor/generator (6) to a direct current, low voltage form for charging the battery (10) and also to a three-phase alternating current form for driving as a motor an alternator (3) which is driven as a generator by the engine (1), an engine revolution detecting means, an accelerator opening detecting means, and an engine boost pressure detecting means. More specifically, the control system comprises a calculating means for calculating a target boost pressure from the engine revolution and the accelerator opening, a first judging means 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 means 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 means. <IMAGE> |
