ABSTRACT:
A throttle control device having a quick response and a control stability in the ISC running mode of an internal combustion engine comprises: feedback control means for outputting an amount of activation for activating a drive motor by using a predetermined control gain such that the real opening of a throttle valve detected by a throttle opening sensor for detecting the real opening of the throttle valve may be equalized to either a desired opening based on at least the depression of the accelerator pedal or a desired opening at the ISC time based on at least the speed of the internal combustion engine; and correction coefficient adjusting means for correcting the activation amount outputted from the feedback control means, with a predetermined correction coefficient on the basis of the decision result of a throttle operation mode deciding means for deciding the operation mode of the throttle valve.
