Abstract
The turbocharged engine control device comprises a basic target torque-deciding part for deciding a basic target torque based on a driving state of a vehicle including an accelerator pedal operation state; a torque reduction amount-deciding part for deciding a torque reduction amount based on a driving state of the vehicle other than the accelerator pedal operation state; a final target torque-deciding part for deciding a final target torque based on the decided basic target torque and the decided torque reduction amount; and an engine output control part for controlling an intake air amount so as to realize a target air amount required for an engine to output the decided final target torque, wherein the engine output control part is operable, when an operating state of the engine falls within a supercharging region, to restrict a reduction in the intake air amount corresponding to a change in the torque reduction amount.
