1. A turbocharged engine control device for controlling an engine equipped with a turbocharger having a compressor provided in an intake passage, based on a driving state of a vehicle mounting the engine, comprising:

  • a basic target torque-deciding part for deciding a basic target torque based on a driving state of the 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 the engine to cause the engine to output the final target torque,wherein the engine output control part is operable, when an operating state of the engine falls within a supercharging region where supercharging by the compressor is performed, to restrict control of the engine corresponding to a change in the torque reduction amount.
