ABSTRACT:
A throttle valve control apparatus for internal combustion engine stabilizes the engine speed in idle operation by always correcting the full closing reference position in ISC using a single throttle valve. Signals of a neutral position signal, air conditioner signal, electrical load signal, accelerator position signal, engine speed, and water temperature are inputted to a CPU in an electronic control unit via an input circuit. The CPU calculates such a throttle opening as to make the actual speed of the internal combustion engine in idle operation equal to a target speed in idle operation stored beforehand, compares the throttle opening with preset upper limit value and lower limit value of the throttle opening in idle operation, and corrects the full closing reference position of the throttle opening on the basis of the result of comparison. As a result, the full closing reference position in the throttle opening of the throttle valve is always corrected.
