This patent describes a throttle valve control apparatus for controlling a degree of opening of throttle valve disposed in an intake system of an internal combustion engine, comprising: accelerator actuation detection means for developing an output in response to an actuation position of an accelerator pedal; opening degree setting means for setting a target degree of opening of the throttle valve based on the actuation position of the accelerator pedal thus detected, thereby generating an output which expresses the target degree of opening; throttle valve opening degree detection means for developing an output in response to an actual degree of opening of the throttle valve; drive speed setting means for setting a speed for driving the throttle valve in response to running conditions of the internal combustion engine; and drive means for driving the throttle valve at the speed which has been set, so as to reduce deviations between the target degree of opening which are obtained from the opening degree setting means.
