A throttle valve control apparatus is described for controlling the throttle valve of the engine of an automotive vehicle comprising: first drive means for rotating the throttle valve; second drive means for rotating the throttle valve and the first drive means as a single unit; first sensing means for sensing the degree of opening of the throttle valve and producing a corresponding output signal; second sensing means for sensing the operational state of the engine and producing a corresponding output signal; third sensing means for sensing the running condition of the vehicle and producing a corresponding output signal; fourth sensing means for sensing the amount by which the driver has depressed the accelerator pedal of the vehicle; and control means responsive to the output signals of the first through fourth sensing means for determining the optimal degree of opening of the throttle valve based on the engine operational state, on the running condition of the vehicle, and on the amount of depression of the accelerator pedal and for controlling the first and second drive means so that the actual degree of opening of the throttle valve equals the optimal value.
