An apparatus is described for use with an internal combustion engine having an accelerator, a throttle value situated within an induction passage, and a brake pedal for controlling movement of the throttle valve in response to a change in the position of the accelerator. This apparatus comprises: a first signal source for generating a first electrical signal indicative of the position of the accelerator; a second signal source for generating a second electrical signal indicative of the accelerator being released; a control circuit including means responsive to the first signal for determining an existing value for accelerator position and a minimum value for accelerator position, means for determining a demand value corresponding to a setting of the position of the throttle valve as a function of a difference between the existing and minimum values, and means responsive to the first and second signals for substituting the existing value for the minimum value when the accelerator remains released and placed at the same position for a predetermined time; and a throttle actuator connected to the control circuit for moving the throttle valve to the determined setting.
