ABSTRACT:
A throttle valve control apparatus for an internal combustion engine uses a target throttle valve opening which is selected between one of a first opening valve determined according to the operation position of the accelerator pedal and a second opening value smaller than the first opening value. When the target throttle valve opening is switched from the second opening value to the first opening value, the driving speed of the throttle valve by a drive mechanism of the apparatus is controlled so as to maintain smooth operation of the engine.
