ABSTRACT:
An apparatus responsive to a change in the position of an accelerator pedal for controlling movement of a throttle valve situated within an induction passage. The apparatus includes a control circuit which determines new and minimum values for the position of the accelerator pedal and determines a demand value corresponding to a setting of the position of the throttle valve as a function of the difference between the new and minimum values. The control circuit substitutes the new value for the minimum value when the accelerator pedal remains released and placed at the same position for a predetermined time.
