1. A throttle valve control device of an internal combustion engine for controlling the opening of a throttle valve by the operation of an accelerator pedal, comprising:

  • a throttle valve;

    a drive motor for said throttle valve;

    a throttle opening sensor for detecting the real opening of said throttle valve;

    feedback control means for outputting an amount of activation for activating said drive motor by using a predetermined control gain so that the real opening of the throttle valve detected by said throttle opening sensor may be identical to either a desired opening based on at least the depression of said accelerator pedal or a desired opening at an ISC time based on at least the speed of the internal combustion engine;

    throttle operation mode deciding means for deciding the operation mode of said throttle valve; and

    correction coefficient adjusting means for correcting said activation amount outputted from said feedback control means with a predetermined correction coefficient on the basis of the decision result of said throttle operation mode deciding means.
