1. An engine control device for controlling an engine based on a plurality of operating states of a vehicle, the engine control device comprising:

  • a processor configured to execute software programs stored in a non-volatile memory of the engine control device, said software programs including;

    a basic target engine torque determinator for setting a target acceleration of the vehicle based on a first operating state of the vehicle, said first operating state of the vehicle being defined by an accelerator pedal operation, and determining a basic target engine torque based on the target acceleration of the vehicle;

    an actual engine torque reduction demand determinator for determining an existence of a demand to reduce an actual engine torque based on a second operating state of the vehicle, said second operating state of the vehicle being defined by a steering wheel operation;

    an actual engine torque reduction amount determinator for determining an actual engine torque reduction amount when the demand to reduce the actual engine torque is determined to exist, the determined actual engine torque reduction amount being based at least in part on a calculated steering speed;

    a final target engine torque determinator for determining a final target engine torque, wherein the determined final target engine torque is obtained by subtracting the determined actual engine torque reduction amount from the determined basic target engine torque; and

    an engine controller for adjusting at least one of a throttle valve position, a fuel injection amount and a fuel injection timing of a fuel injector, an ignition timing of an ignition plug, and open-close timings of an intake valve and an exhaust valve such that the actual engine torque is reduced so as to output the determined final target engine torque.
